[0001] This application claims priority of Chinese Patent Application No. 202310097721.8, filed on Feb. 6, 2023, the entire contents of which are hereby incorporated by reference.

[0002] The present disclosure relates to the field of gas transmission technology, and in particular, to methods and Internet of Things systems for installing a gas pipeline compensator of smart gas.

[0003] In the process of gas transmission through a gas pipeline, a change of gas and environmental temperature may cause a metal pipeline to stretch with heat and contract with cold, so that a length of the gas pipeline may change. At the same time, foundation settlement, etc. may also cause stretching and contracting and displacement of the gas pipeline. The stretching and contracting of the gas pipeline may create huge stress, which often leads to pipeline damage and leakage and affects normal production activities. During the planning and installation of the gas pipeline, to relieve the stress, the stretching and contracting of the gas pipeline may be compensated and deformation of the gas pipeline may be absorbed generally using a manner for installing a compensator. However, for the gas pipelines with different features and different environments in which the gas pipelines operate, the possible stretching, contracting, and deformation of the gas pipeline may also be different. It may be difficult to effectively compensate the gas pipeline using the manner for installing a fixed compensator.

[0004] Therefore, it is desirable to provide methods and Internet of Things systems for installing a gas pipeline compensator of smart gas to improve the effectiveness of gas pipeline compensation.

[0005] According to one or more embodiments of the present disclosure, a method for installing a gas pipeline compensator of smart gas is provided. The method may be implemented by a processor of a smart gas device management platform of an Internet of Things system for installing a gas pipeline compensator of smart gas and may include: obtaining a pipeline feature and an estimated operation feature of a target pipeline; generating an estimated stretching and contracting feature of the target pipeline based on the pipeline feature and the estimated operation feature; and generating an installation parameter of the compensator based on the estimated stretching and contracting feature, wherein the installation parameter at least includes a device parameter of the compensator.

[0006] According to one or more embodiments of the present disclosure, an Internet of Things system for installing a gas pipeline compensator of smart gas is provided. The Internet of Things system may include a smart gas user platform, a smart gas service platform, a smart gas management platform, a smart gas sensor network platform, and a smart gas object platform. The smart gas user platform may include a plurality of smart gas user sub-platforms. The smart gas service platform may include a plurality of smart gas service sub-platforms and the different smart gas service sub-platforms may correspond to the different smart gas user sub-platforms. The smart gas management platform may include a smart gas indoor management sub-platform, a smart gas pipeline network management sub-platform, and a smart gas data center. The smart gas sensor network platform may include a smart gas indoor sensor network sub-platform and a smart gas pipeline network sensor network sub-platform. The smart gas object platform may include a smart gas indoor object sub-platform and a smart gas pipeline network object sub-platform. The smart gas indoor object sub-platform may correspond to the smart gas indoor sensor network sub-platform. The smart gas pipeline network object sub-platform may correspond to the smart gas pipeline network sensor network sub-platform. The smart gas object platform may be configured to obtain a pipeline feature and an estimated operation feature of a target pipeline and upload the pipeline feature and the estimated operation feature to the smart gas data center of the smart gas management platform based on the smart gas sensor network sub-platform corresponding to the smart gas object platform. The smart gas management platform may be configured to generate an estimated stretching and contracting feature of the target pipeline based on the pipeline feature and the estimated operation feature; generate an installation parameter of the compensator based on the estimated stretching and contracting feature, wherein the installation parameter at least includes a device parameter of the compensator; and transmit the installation parameter of the compensator to the smart gas service platform based on the smart gas data center. The smart gas service platform may be configured to upload the installation parameter of the compensator to the smart gas user platform.

[0007] According to one or more embodiments of the present disclosure, a non-transitory computer-readable storage medium storing computer instruction is provided. When reading the computer instruction in the storage medium, the computer may execute the method for installing a gas pipeline compensator of smart gas.

[0017] To more clearly illustrate the technical solutions related to the embodiments of the present disclosure, a brief introduction of the drawings referred to the description of the embodiments is provided below. Obviously, the drawings described below are only some examples or embodiments of the present disclosure. Those having ordinary skills in the art, without further creative efforts, may apply the present disclosure to other similar scenarios according to these drawings. Unless obviously obtained from the context or the context illustrates otherwise, the same numeral in the drawings refers to the same structure or operation.

[0018] It should be understood that the “system,” “device,” “unit,” and/or “module” used herein are one method to distinguish different components, elements, parts, sections, or assemblies of different levels. However, if other words can achieve the same purpose, the words may be replaced by other expressions.

[0019] As used in the disclosure and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise; the plural forms may be intended to include singular forms as well. In general, the terms “comprise,” “comprises,” and/or “comprising,” “include,” “includes,” and/or “including,” merely prompt to include steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive listing. The methods or devices may further include other steps or elements.

[0020] The flowcharts used in the present disclosure illustrate the operation that the system implements according to the embodiment of the present disclosure. It should be understood that the foregoing or following operation may not necessarily be performed exactly in order. Instead, the operation may be processed in reverse order or simultaneously. Besides, one or more other operations may be added to these processes, or one or more operations may be removed from these processes.

[0021] A gas pipeline may generate different stretching and contracting amounts due to a change in an external environment in which the gas pipeline operates at different times and changes in temperature and pressure of transmitted gas. For example, a climate change in different seasons in a same region and a climate difference in different regions may lead to changes in the temperature and humidity of the environment in which the gas pipeline operates and the temperature and pressure of the internally transmitted gas may also change. As a result, the gas pipeline may generate different stretching and contracting amounts in different seasons and regions. Naturally, required compensation amount may vary with the different seasons and regions. At the same time, for different compensation needs, it may also be necessary to use different models and materials of compensators to compensate. If no distinction is made, it may be difficult to achieve effective compensation for the gas pipeline using a same compensation scheme and may not be effective in eliminating stress damage caused by stretching, contracting, and deformation of gas pipeline.

[0022] In view of this, according to some embodiments of the present disclosure, it is desirable to provide a method for installing a gas pipeline compensator of smart gas. The possible stretching and contracting amount generated by the gas pipeline may be estimated based on data related to an operating environment (e.g., temperature, humidity, soil conditions, etc.) and a feature of a transmitted medium after the gas pipeline is put into operation and an installation parameter of the compensator may be determined based on the stretching and contracting amount, which can improve the accuracy and rationality of the compensator installation and the effectiveness of the gas pipeline compensation.

Each smart gas management sub-platform may be set up independently and may interact with the smart gas data center for data. For example, the each smart gas management sub-platform may obtain data (e.g., the pipeline feature and the estimated operation feature) uploaded by the smart gas sensor network platform 140 from the smart gas data center and process the data, and then feedback a processing result (e.g., a compensator installation scheme) to the smart gas data center.

As another example, the smart gas data center may classify, summarize, and store the data processing result fed back by each smart gas device management sub-platform.

[0036] In some embodiments, the smart gas indoor device management sub-platform and the smart gas pipeline network device management sub-platform may include a device operation monitoring and warning module and a device remote management module.

[0042] It should be understood that the present embodiments in the present disclosure mainly relate to the method for installing a gas pipeline compensator of smart gas. Therefore, the system for implementing the method for installing the compensator is mainly implemented by relying on the government user sub-platform, the smart operation service sub-platform, the smart gas pipeline network device management sub-platform, the smart gas data center, the smart gas pipeline network device sensor network sub-platform, and the smart gas pipeline network device object sub-platform.

[0043] It should be noted that the above description of the Internet of Things system for installing a gas pipeline compensator of smart gas and modules thereof are merely provided for the purposes of illustration, and not intended to limit the scope of the present disclosure. Understandably, for those skilled in the art, after understanding the principle of the system, it is possible to randomly combine each module or form a subsystem to connect with other modules without departing from this principle. In some embodiments, the smart gas user platform 110, the smart gas service platform 120, the smart gas device management platform 130, the smart gas sensor network platform 140, and the smart gas object platform 150 disclosed in FIG. 1 may be different modules in one system, or one module implementing the functions of two or more of the above modules. For example, each module may share a storage module and each module may also have its own storage module. Such variations are within the scope of protection of the present disclosure.

[0044] FIG. 2 is a flowchart illustrating an exemplary process of a method for installing a gas pipeline compensator of smart gas according to some embodiments of the present disclosure. In some embodiments, the process 200 may be performed by the smart gas device management platform 130. As shown in FIG. 2, the process 200 includes the following operations.

[0045] In step 210, obtaining a pipeline feature and an estimated operation feature of a target pipeline.

[0046] The target pipeline may refer to a gas pipeline that requires compensator installation. For example, the target pipeline may refer to a newly laid gas pipeline, a gas pipeline that requires compensator replacement or adjustment, etc.

[0047] The pipeline feature may refer to information that reflects a feature of a gas pipeline. For example, the pipeline feature may include a length, a diameter, a pipeline material, etc. of the gas pipeline. In some embodiments, the pipeline feature may be obtained from gas pipeline laying planning data. For example, the length and the diameter of each section of pipeline, and the material of a pipeline device used in a planning region may be obtained from the gas pipeline laying planning data.

[0048] The estimated operation feature may refer to an estimated feature of a transmitted medium (gas) after the target pipeline is put into service. For example, the estimated operation feature may include a feature such as a temperature, a pressure, etc. of the transmitted gas after the target pipeline is placed into service. In some embodiments, the estimated operation feature may be obtained by analyzing historical gas data. For example, the feature such as the temperature, the pressure, etc. of the gas may be obtained from the gas pipeline network that has been laid in a same region and an average value may be calculated as the estimated operation feature of the target pipeline.

[0049] In step 220, generating an estimated stretching and contracting feature of the target pipeline based on the pipeline feature and the estimated operation feature.

[0050] The estimated stretching and contracting feature may refer to feature information of stretching and contracting that may be generated by the target pipeline. For example, the estimated stretching and contracting feature may include a possible stretching and contracting amount of the target pipeline, a stretching and contracting speed, etc.

[0051] In some embodiments, the stretching and contracting amount of the target pipeline may be determined based on a linear expansion coefficient, a pipeline length, and a temperature difference. For example, the target pipeline stretching and contracting amount=the linear expansion coefficient*the pipeline length*the temperature difference. The linear expansion coefficient denotes a linear expansion coefficient of the pipeline material, which may be obtained from a factory quality parameter of the pipeline, etc., the pipeline length denotes a length of the target pipeline, which may be obtained based on the pipeline installation scheme data, and the temperature difference denotes a difference between a temperature when the target pipeline operate and a temperature when the target pipeline is installed, which may be preset.

[0052] In some embodiments, the stretching and contracting speed of the target pipeline may be determined by monitoring the stretching and contracting amount of the target pipeline in an experimental environment for a certain period of time and dividing the stretching and contracting amount by the monitoring time. The experimental environment may simulate a plurality of installation and operation environments that the target pipeline may involve.

[0053] In some embodiments, the smart gas device management platform 130 may analyze based on the pipeline feature and the estimated operation feature and generate the estimated stretching and contracting feature of the target pipeline in combination with relevant historical data of an existing gas pipeline. For example, the smart gas device management platform 130 may obtain a stretching and contracting amount feature of another laid pipeline with a pipeline feature and an estimated operation feature same as or similar to those of the target pipeline as the estimated stretching and contracting feature of the target pipeline.

[0054] In some embodiments, the estimated stretching and contracting feature may include a first estimated stretching and contracting amount sequence. The smart gas equipment management platform 130 may determine a first temperature sequence of the target pipeline and determine the first estimated stretching and contracting amount sequence of the target pipeline based on the pipeline feature, the estimated operation feature, and the first temperature sequence. The first temperature sequence and the first estimated stretching and contracting amount sequence may correspond to a preset scenario. Further description regarding determining the first estimated stretching and contracting amount sequence may be found in FIG. 3 and the related description thereof.

[0055] In some embodiments, the smart gas device management platform 130 may generate the estimated stretching and contracting feature based on the first estimated stretching and contracting amount sequence. For example, the first estimated stretching and contracting amount sequence may be combined to form the estimated stretching and contracting feature.

[0056] In step 230, generating an installation parameter of the compensator based on the estimated stretching and contracting feature, wherein the installation parameter at least includes a device parameter of the compensator.

[0057] The installation parameter of the compensator may refer to installation information of the compensator in the target pipeline. For example, the installation parameter of the compensator may include a device parameter of the compensator, an installation quantity, an installation interval, an installation location, etc. The compensator may be a device used to compensate for stress generated by the stretching, contracting, and deformation of the gas pipeline. The compensator may include a corrugated compensator, a square compensator, a packing compensator, an expansion compensator, etc.

[0058] The device parameter of the compensator may refer to a parameter of the compensator itself. For example, the device parameter of the compensator may include a model, a material, a wall thickness, a count of corrugations, a wave interval of the compensator, etc.

[0059] In some embodiments, the smart gas device management platform 130 may generate the installation parameter of the compensator based on the estimated stretching and contracting feature of the target pipeline in combination with stretching and contracting features of other gas pipelines installed with compensators. For example, the smart gas device management platform 130 may determine an installation parameter of a compensator of a gas pipeline installed with a compensator that have a same or similar stretching and contracting feature as the installation parameter of the compensator of the target pipeline based on the estimated stretching and contracting feature of the target pipeline.

[0060] In some embodiments, the smart gas device management platform 130 may generate a plurality of sets of first candidate compensation schemes by selecting compensators with different installation parameters, predict an estimated compensation performance of the compensator under different first candidate compensation schemes, wherein the estimated compensation performance is determined based on a compensation feature of the compensator under the estimated stretching and contracting feature, and determine a first compensation scheme based on the estimated compensation performance and determine the installation parameter of the compensator based on the first compensation scheme. Further description regarding determining the installation parameter of the compensator based on the first candidate compensation scheme may be found in FIG. 6 and the related description thereof.

[0061] In some embodiments, the installation parameter may also include an installation distance. The smart gas device management platform 130 may generate a plurality of sets of second candidate compensation schemes by selecting compensators with different installation parameters and presetting different installation distances, for each set of second candidate compensation schemes, calculate the estimated compensation performance of each compensator at an interval of the installation distance corresponding to the second candidate compensation scheme, wherein the estimated compensation performance is determined based on a second estimated stretching and contracting amount sequence of the target pipeline subsection connected to both ends of the compensator, and determine a second compensation scheme based on the estimated compensation performance and determine the installation distance of the compensator based on the second compensation scheme. Further description regarding determining the installation distance of the compensator may be found in FIG. 7 and the related description thereof.

[0062] In some embodiments of the present disclosure, the possible stretching and contracting feature of the target pipeline may be estimated in advance by obtaining the pipeline feature, the estimated operation feature, etc. of the target pipeline and then a suitable compensator installation scheme may be determined based on the stretching and contracting feature, which can avoid inadequate compensation or excessive compensation of the gas pipeline (resulting in waste of resources) caused by blind installation of compensators, and at the same time consider the influence of the feature of the target pipeline and future operating environmental feature on the stretching and contracting amount of the gas pipeline, thereby determining the installation parameter of the compensator more accurately and reasonably, improving the effectiveness of installation of the gas pipeline compensator, and increasing the service life of the gas pipeline.

[0063] FIG. 3 is a flowchart illustrating an exemplary process for determining a first estimated stretching and contracting amount sequence according to some embodiments of the present disclosure. In some embodiments, the process 300 may be performed by the smart gas device management platform 130.

[0064] In some embodiments, the estimated stretching and contracting feature may include the first estimated stretching and contracting amount sequence. In some embodiments, the smart gas device management platform 130 may determine an estimated stretching and contracting feature of a target pipeline based on a pipeline feature and an estimated operation feature, which may include the following operations shown in FIG. 3.

[0065] In step 310, determining a first temperature sequence of the target pipeline.

[0066] In some embodiments, the first temperature sequence may correspond to a preset scenario. The preset scenario may refer to an assumed transportation scenario, an assumed operation scenario, and an assumed emergency scenario of the gas pipeline. For example, the transportation scenario may include a possible transportation environment of the gas pipeline and a temperature, a pressure, and a humidity of the transportation environment. The operation scenario may include a possible operation environment of the gas pipeline (e.g., temperature, soil feature), a temperature and a pressure of the transmitted medium, etc. The emergency scenario may include a scenario such as an earthquake, an urban construction, a heavy object compression, a fire, etc., that may cause stress in the gas pipeline.

[0067] In some embodiments, the preset scenario may include a plurality of scenarios. Selection of the plurality of preset scenarios may be related to a future environmental feature when the target pipeline is put into operation.

[0068] The future environmental feature may refer to a natural environmental feature of a region where the gas pipeline will operate in a future time. For example, the environmental feature may include a feature such climate, temperature, humidity, soil, etc. of the region where the gas pipeline operates. The future time may refer to a time after the gas pipeline is put into operation. For example, if the gas pipeline is put into operation on Jan. 1, 2025, the future time may be a time after Jan. 1, 2025.

[0069] In some embodiments, the smart gas equipment management platform 130 may select the preset scenario based on the future environmental feature of the target pipeline when the target pipeline is put into operation. For example, during the selection of the preset scenario, a preset scene that is same as or similar to the future environmental feature when the target pipeline is put into operation may be selected.

[0070] In some embodiments, during the selection of the preset scenario, some extreme scenarios that may occur when the target pipeline is put into operation may be selected. For example, the extreme scenario may include a high temperature scenario, a heavy drought scenario, a heavy rain scenario, a flood scenario, etc.

[0071] The stretching and contracting amounts of the target pipeline under the plurality of future preset scenarios may be determined by selecting the preset scenario that is same as or similar to the future environmental feature when the target pipeline is put into operation, which is more in line with the stretching and contracting amount that the target pipeline may generate in an actual operating environment in the future and can provide reliable data support for the subsequent determination of the installation parameter of the compensator. At the same time, some preset scenarios under extreme conditions may be selected, which can prevent the extreme conditions that may occur during the operation of the target pipeline in advance, prepare a response scheme in advance, and improve a risk resistance capacity of the target pipeline.

[0072] The first temperature sequence may refer to a sequence composed of temperatures of the target pipeline at a plurality of time points in the preset scenario. The plurality of time points may be future time points after the target pipeline of each preset scenario is put into operation. For example, if the gas pipeline is put into operation on Jan. 1, 2025 and the preset scenario is the high temperature scenario, the plurality of time points may be preset times in the high temperature scenario after Jan. 1, 2025 and the first temperature sequence may be a sequence composed of temperatures at the plurality of time points.

[0073] In some embodiments, the smart gas device management platform 130 may determine temperature data at the plurality of future time points in each preset scenario after the target pipeline is put into operation and form the first temperature sequence of the target pipeline corresponding to the preset scenario based on temperature data in the corresponding preset scenario.

[0074] In some embodiments, the smart gas device management platform 130 may obtain a first gas temperature sequence and a first environmental temperature sequence of the preset scenario, and determine the first temperature sequence of the target pipeline based on the first gas temperature sequence, the first environmental temperature sequence, and a medium feature of the target pipeline. Further description regarding determining the first temperature sequence may be found in FIG. 4 and the related description thereof.

[0075] In step 320, determining the first estimated stretching and contracting amount sequence of the target pipeline based on the pipeline feature, the estimated operation feature, and the first temperature sequence.

[0076] The first estimated stretching and contracting amount sequence may refer to a sequence composed of estimated stretching and contracting amounts of the target pipeline at a plurality of time points. The plurality of time points may be the same as time points corresponding to a plurality of temperatures in the first temperature sequence. In some embodiments, the first estimated stretching and contracting amount sequence may correspond to a preset scenario.

[0077] In some embodiments, the smart gas device management platform 130 may predict the estimated stretching and contracting amounts at the plurality of time points after the target pipeline is put into operation to form the first estimated stretching and contracting amount sequence based on the plurality of estimated stretching and contracting amounts.

[0100] It should be noted that the above description of the process 300 is merely provided for the purposes of illustration, and is not intended to limit the scope of the present disclosure. For those skilled in the art, various amendments and variations can be made to the process 300 under the guidance of the present disclosure. However, these amendments and variations remain within the scope of the present disclosure.

[0102] In step 410, obtaining a first gas temperature sequence and a first environmental temperature sequence of a preset scenario.

[0103] The first gas temperature sequence may refer to a sequence composed of temperatures of gas transmitted in a target pipeline at a plurality of time points under each preset scenario. In some embodiments, the smart gas device management platform 130 may obtain the gas temperatures of the target pipeline at the plurality of time points under each preset scenario after the target pipeline is put into operation and generate the first gas temperature sequence based on the gas temperatures of the target pipeline at the plurality of time points.

In some embodiments, the smart gas management platform may simulate the operation of the target pipeline under the plurality of preset scenarios through a simulation experiment and then monitor the environmental temperatures at the plurality of time points as the environmental temperatures of the target pipeline at the plurality of time points under each preset scenarios.

[0105] In step 420, determining the first temperature sequence of the target pipeline based on the first gas temperature sequence, the first environmental temperature sequence, and a medium feature of the target pipeline.

[0106] In some embodiments, the smart gas device management platform 130 may obtain temperatures at a plurality of historical time points of other operated pipelines that have a first gas temperature sequence, an environmental temperature sequence, and a medium feature same as those of the target pipeline and a pipeline operation scenario same as each preset scenario and determine the temperature sequence of the target pipeline under each preset scenario.

[0107] In some embodiments, the determining the first temperature sequence of the target pipeline based on the first gas temperature sequence, the first environmental temperature sequence, and the medium feature of the target pipeline may include: inputting the first gas temperature sequence, the first environmental temperature sequence, and the medium feature of the target pipeline into a temperature sequence model and outputting the first temperature sequence of the target pipeline. The temperature sequence model may be a machine learning model.

[0108] In some embodiments, the temperature sequence model may be a Deep Neural Networks (DNN) model, a Recurrent Neural Networks (RNN) model, other custom networks model, or any combination thereof.

[0109] FIG. 5 is an exemplary schematic diagram illustrating determining a first temperature sequence based on a temperature sequence model according to some embodiments of the present disclosure. As shown in FIG. 5, an input of the temperature sequence model 540 may include a first gas temperature sequence 510, a first environmental temperature sequence 520, and a medium feature 530 of a target pipeline. An output of the temperature sequence model 540 may be a first temperature sequence 550 of the target pipeline.

[0110] In some embodiments, the temperature sequence model 540 may be obtained by training. In some embodiments, a first training sample for training the temperature sequence model 540 may be data for performing a simulation experiment, including a sample first gas temperature sequence, a sample first environmental temperature sequence, and a sample medium feature of the target pipeline. The first training sample may be obtained by presetting or monitoring when the simulation experiment is performed. In some embodiments, a first training label for training the temperature sequence model 540 may be an actual first temperature sequence at a plurality of time points obtained by monitoring in the simulation experiment data.

[0111] In some embodiments, the smart gas device management platform 130 may input the first training sample into an initial temperature sequence model to obtain an initial first temperature sequence, construct a loss function based on the initial first temperature sequence and the first training label, and obtain a trained temperature sequence model by updating a parameter of the initial temperature sequence model parameter based on the loss function.

[0112] In some embodiments of the present disclosure, the self-learning capability of the machine learning model may be used to learn a relationship between the temperature of the target pipeline and the gas temperature, the environmental temperature, and the medium feature of the target pipeline by processing the first gas temperature sequence, the first environmental temperature sequence, and the medium feature of the target pipeline using the temperature sequence model, so that the accuracy of predicting the temperature of the target pipeline can be improved.

[0113] In some embodiments, the first temperature sequence of the target pipeline may include second temperature sequences of a plurality of target pipeline subsections. The second temperature sequence of each target pipeline subsection may be related to a gas transportation direction, a gas transportation distance, and a second environmental temperature sequence of the target pipeline subsection. The second environmental sequence may be determined based on an environmental temperature corresponding to the target pipeline subsection. For example, the environmental temperatures of the target pipeline subsection at a plurality of time points may be combined to form the second environmental temperature sequence.

[0114] The gas transportation direction may refer to a direction of gas flow in the target pipeline. The gas transportation distance may refer to a distance that the gas is transmitted from a gas source point to the target pipeline subsection. In some embodiments, the gas transportation distance may be determined based on a distance from the target pipeline subsection to the gas source point. For example, the distance from the target pipeline subsection to the gas source point may be directly determined as the gas transportation distance.

[0115] The distance from the gas source point may refer to a distance from a location of the target pipeline subsection relative to a gas transportation starting point. In some embodiments, the smart gas device management platform 130 may determine length information of the target pipeline subsection from the gas source point based on laying planning data of the gas pipeline. For example, the smart gas device management platform 130 may determine the location of the target pipeline subsection and the length information of the gas pipeline based on the laying planning data of the gas pipeline and determine the distance from the target pipeline subsection to the gas source point based on the location and length information.

[0116] In some embodiments, the smart gas device management platform 130 may determine a gas temperature of the target pipeline subsection based on the gas transportation direction and the gas transportation distance of the target pipeline subsection. For example, the gas temperature of the target pipeline subsection may be determined based on a gas temperature at the gas source point, the gas transportation direction, the gas transportation distance, and an attenuation coefficient by determining the attenuation coefficient of the gas temperature during transportation (e.g., how many meters is transported, how much the gas temperature decreases) through measurement or experimental simulation. The second gas temperature sequence of the target pipeline subsection may be composed by obtaining the gas temperatures of the target pipeline subsection at a plurality of time points.

[0117] The gas temperature in the gas pipeline may attenuate over the transportation distance as the gas is transmitted from the gas source point. A more accurate second gas temperature sequence can be determined by determining the gas transportation direction and the gas transportation distance of the target pipeline subsection.

[0118] In some embodiments, the smart gas device management platform 130 may determine the second temperature sequence of the target pipeline subsection by processing the second gas temperature sequence, the second environmental sequence, and a medium feature of the target pipeline subsection based on the temperature sequence model. Specific description of determining the second temperature sequence of the target pipeline subsection based on the temperature sequence model may be found in FIG. 3 and the related description thereof.

[0119] In some embodiments, the smart gas device management platform 130 may determine the first temperature sequence of the target pipeline based on the second temperature sequences of the plurality of target pipeline subsections. For example, the second temperature sequences of the plurality of target pipeline subsections may be combined in an order of the location of each target pipeline subsection to form the first temperature sequence of the target pipeline. As another example, an average of the temperature corresponding to each time point in the second temperature sequence of the plurality of target pipeline subsections may be calculated. The average may be combined to form the first temperature sequence of the target pipeline.

[0120] In some embodiments, the second temperature sequence of each target pipeline subsection may be also related to a second temperature sequence of a target pipeline subsection adjacent to each target pipeline subsection.

[0121] The target pipeline subsection adjacent to each target pipeline subsection (also referred to as adjacent target pipeline subsection of the target pipeline subsection) may refer to an adjacent subsection of the target pipeline subsection that currently needs to determine the second temperature sequence. For example, if the target pipeline is sequentially divided into three sections A, B, and C, the target pipeline subsection adjacent to the target pipeline subsection A may be B, the target pipeline subsections adjacent to the target pipeline subsection B may be A and C, and the target pipeline subsection adjacent to the target pipeline subsection C may be B.

[0122] In some embodiments, the smart gas device management platform 130 may determine the second temperature sequence of the target pipeline subsection by inputting the second temperature sequence of the target pipeline subsection adjacent to the target pipeline subsection into the temperature sequence model. That is, the input of the temperature sequence model 540 as shown in FIG. 5 may include the second gas temperature sequence of the target pipeline subsection, the second environmental temperature sequence, the medium feature, and the second temperature sequence of the target pipeline subsection adjacent to each target pipeline subsection. The output of the temperature sequence model 540 may be the second temperature sequence of the target pipeline subsection.

[0123] In some embodiments of the present disclosure, the second gas temperature sequence of the target pipeline subsection may be determined based on the gas transportation direction and the gas transportation distance of the target pipeline subsection and the second temperature sequence of the target pipeline subsection may be determined based on the second gas temperature sequence, the second environmental temperature sequence, the medium feature, and the second temperature of the target pipeline subsection adjacent to each target pipeline subsection, which fully considers various kinds of information that may affect the temperature of the target pipeline subsection, improves the accuracy of the determined second temperature sequence of the target pipeline subsection, and provides reliable data support for the subsequent determination of the first temperature sequence of the target pipeline based on the second temperature sequence of the target pipeline subsection.

[0124] In some embodiments of the present disclosure, the first temperature sequences of the target pipeline in the plurality of possible scenarios after the target pipeline is put into operation may be determined in advance by determining the first temperature sequences of the target pipeline in the plurality of preset scenarios, which can provide a data basis for determining the corresponding stretching and contracting amount feature and improve the data process efficiency.

[0125] It should be noted that the above description of the process 400 is merely provided for the purposes of illustration, and is not intended to limit the scope of the present disclosure. For those skilled in the art, various amendments and variations can be made to the process 400 under the guidance of the present disclosure. However, these amendments and variations remain within the scope of the present disclosure.

[0126] FIG. 6 is a flowchart illustrating an exemplary process for determining an installation parameter of a compensator according to some embodiments of the present disclosure. In some embodiments, the process 600 may be performed by the smart gas device management platform 130. As shown in FIG. 6, the process 600 may include the following operations.

[0127] In step 610, generating a plurality of sets of first candidate compensation schemes by selecting compensators with different installation parameters.

[0128] The first candidate compensation scheme may refer to a scheme that may serve as a final compensator compensation scheme.

[0129] In some embodiments, the smart gas device management platform 130 may generate the plurality of sets of first candidate compensation schemes by selecting a plurality of compensators with different installation parameters. The compensator with each set of installation parameters may correspond to a set of first candidate compensation schemes. For example, the smart gas device management platform 130 may generate the plurality of sets of first candidate compensation schemes by randomly combining compensators with different installation quantities, different installation locations, and different device parameters (e.g., a material, a count of corrugations, a wave interval, a wall thickness).

[0130] In step 620, predicting an estimated compensation performance of the compensator under different first candidate compensation schemes, wherein the estimated compensation performance is determined based on a compensation feature of the compensator under the estimated stretching and contracting feature.

[0131] The estimated compensation performance may refer to an estimated compensation performance and a compensation effect on a target pipeline after the compensator is installed based on the different first candidate compensation schemes. For example, the estimated compensation performance may include an amount of compensation to the target pipeline after the installation of the compensator.

[0132] The compensation feature may refer to feature information when the installed compensator compensates for the target pipeline. For example, the compensation feature may include whether compensator elasticity is capable of supporting the stretching and contracting of the target pipeline when a maximum or minimum estimated stretching and contracting amount of the target pipeline is reached after the compensator is installed. As another example, the compensation feature may include whether the compensator has sufficient sensitivity to adapt to a stretching and contracting frequency of the target pipeline when the target pipeline stretches and contracts frequently.

[0133] In some embodiments, the smart gas device management platform 130 may determine the compensation feature of the target pipeline of the compensator under the estimated stretching and contracting amount by obtaining historical deformation data and a pressure sensor degree of a laid gas pipeline. In some embodiments, the smart gas device management platform 130 may also simulate a plurality of sets of first candidate compensation schemes corresponding to the target pipeline under the estimated stretching and contracting amount through a simulation experiment to determine the compensation feature of the compensator in each first candidate compensation scheme.

[0134] In some embodiments, the smart gas device management platform 130 may determine whether the elasticity of the compensator can support the stretching and contracting of the gas pipeline by obtaining historical pressure data collected by the corresponding pressure sensor when the compensator is stretched to a maximum deformation amount in the laid pipeline.

[0135] For example, the smart gas device management platform 130 may obtain a change in the historical pressure data of the pressure sensor when the compensator is stretched to the maximum deformation amount and determine whether the elasticity of the compensator can support the stretching and contracting of the gas pipeline. If the historical pressure data of the pressure sensor is still increasing, it may indicate that the elasticity of the compensator cannot support the stretching and contracting of the gas pipeline. When the compensator is stretched to the maximum deformation amount, it is determined whether a historical reading of the pressure sensor meets a standard reading corresponding to the maximum deformation amount of the compensator. If the historical reading of the pressure sensor is greater than the standard reading, it may mean that the elasticity of the compensator cannot support the stretching and contracting amount of the gas pipeline. The standard reading of the pressure sensor corresponding to the maximum deformation amount of the compensator may be determined by an experiment.

[0136] In some embodiments, the smart gas device management platform 130 may determine whether the compensator has sufficient sensitivity to adapt to the stretching and contracting frequency of the gas pipeline by obtaining the historical pressure data collected by the pressure sensor of the compensator in the laid gas pipeline. For example, the smart gas device management platform 130 may collect the historical pressure data of the gas pipeline through the pressure sensor when the stretching and contracting frequency of the gas pipeline is maximum and compare the historical pressure data with a preset pressure value. If the historical pressure data of the gas pipeline is greater than the preset pressure value when the stretching and contracting frequency of the gas pipeline is maximum, it may mean that the compensator does not have sufficient sensitivity to adapt to the stretching and contracting frequency of the gas pipeline.

[0137] It should be understood that a plurality of compensators may be included in each first candidate compensation scheme. Therefore, the compensation feature of each compensator in each first candidate compensation scheme may need to be determined.

[0138] In some embodiments, the smart gas device management platform 130 may determine the estimated compensation performance of the compensators of each first candidate compensation scheme based on the compensation features of the compensators of each first candidate compensation scheme corresponding to the target pipeline. For example, the smart gas device management platform 130 may score the compensation feature of each compensator of each first candidate compensation scheme and average a plurality of scores as the estimated compensation performance of the compensators of the first candidate compensation scheme. The score may be determined based on the elasticity and sensitivity of the compensator in the compensator compensation feature. A scoring criteria may be preset.

[0139] In step 630, determining a first compensation scheme based on the estimated compensation performance and determining the installation parameter of the compensator based on the first compensation scheme.

[0140] The first compensation scheme may refer to an optimal compensator compensation scheme suitable for the target pipeline.

[0141] In some embodiments, the smart gas device management platform 130 may determine the optimal first compensation scheme based on the score corresponding to the compensation performance. For example, the first candidate compensation scheme with a highest score corresponding to the compensation performance may be determined as the first compensation scheme.

[0142] In some embodiments, the smart gas device management platform 130 may determine the installation parameter based on the compensation parameter of the compensator in the optimal first compensation scheme. For example, the smart gas device management platform 130 may determine the location, the quantity, and the device parameter of a compensator to be installed based on the device parameter, the installation location, and the installation quantity of the compensation parameter.

[0143] In some embodiments, the installation parameter may also include a pre-stretching degree of the compensator and the pre-stretching degree may be determined based on a stretching performance of the compensator and stretching and contracting balance of the target pipeline.

[0144] The pre-stretching degree may refer to an appropriate length of the compensator that is pre-stretched.

[0145] The stretching performance may refer to a maximum extent or a maximum length that the compensator can be stretched. In some embodiments, the stretching performance of the compensator may be obtained through an experiment. For example, the maximum length that the compensator can be stretched may be determined as the stretching performance by performing a stretching experiment on the compensator.

[0146] The stretching and contracting balance may refer to a stretching and contracting amount of the target pipeline as the target pipeline remains in balance during a stretching and contracting process, including a contracting amount during contracting balance and a stretching amount during stretching balance. In some embodiments, the smart gas device management platform 130 may determine the stretching and contracting balance based on a stretching and contracting amount feature of the target pipeline. For example, the stretching and contracting amount during the stretching and contracting balance may be extracted from the stretching and contracting amount feature.

[0147] In some embodiments, the smart gas device management platform 130 may determine the pre-stretching degree based on the stretching performance of the compensator and the stretching and contracting balance of the target pipeline. For example, a length of the compensator to be stretched (the compensator may relatively need to be stretched if the gas pipeline contracts) may be determined based on the contracting amount of the target pipeline during the contracting balance and a length of the compensator to be contracted may be determined based on the stretching amount of the target pipeline during the stretching balance. Further, the smart gas device management platform 130 may determine the pre-stretching degree based on the stretching performance of the compensator in combination with the length to be stretched and the length to be contracted.

[0148] Exemplarily, the smart gas device management platform 130 may first compare the length of the compensator to be stretched with the length of the compensator to be contracted. If the length of the compensator to be stretched is greater than the length of the compensator to be contracted, the pre-stretching degree may be determined based on the length of the compensator to be stretched. Conversely, the pre-stretching degree may be based on the length of the compensator to be contracted. Further, the smart gas device management platform 130 may compare the length of the compensator to be stretched with the stretching performance of the compensator (the maximum length that the compensator can be stretched). If the length of the compensator to be stretched is greater than the stretching performance of the compensator, the stretching performance of the compensator may be determined as the pre-stretching degree. Conversely, the length of the compensator to be stretched may be determined as the pre-stretching degree.

[0149] Before being installed, the compensator may need to be pre-stretched so that the compensator may be installed at both ends of the gas pipeline while remaining stretched, which can play a compensating role for the gas pipeline when the gas pipeline expands (squeezes the compensator at both ends). Obviously, the pre-stretching degree may not be stretched to a limit state of the compensator, so that when the compensator in the state is installed in the gas pipeline, the compensator in the limit state may not compensate for the gas pipeline when the gas pipeline contracts and damage may be caused to the compensator. Therefore, the determination of the appropriate pre-stretching degree can improve the compensation performance of the compensator and can also extend the service life of the compensator.

[0150] In some embodiments of the present disclosure, the optimal first compensation scheme may be determined by selecting a plurality of sets of first candidate compensation schemes and based on the compensation performance of the compensator in each first candidate compensation scheme and the installation parameter may be determined based on the optimal first compensation scheme. The reasonableness and effectiveness of the determined compensation scheme can be improved by selecting the optimal compensation scheme in the plurality of possible compensation schemes that are designed.

[0151] It should be noted that the above description of the process 600 is merely provided for the purposes of illustration, and is not intended to limit the scope of the present disclosure. For those skilled in the art, various amendments and variations can be made to the process 600 under the guidance of the present disclosure. However, these amendments and variations remain within the scope of the present disclosure.

[0152] FIG. 7 is a flowchart illustrating an exemplary process for determining an installation distance of a compensator according to some embodiments of the present disclosure. In some embodiments, the process 700 may be performed by the smart gas device management platform 130.

[0153] In some embodiments, an installation parameter may also include the installation distance. As shown in FIG. 7, the installation distance may be determined by the following operations.

[0154] In step 710, generating a plurality of sets of second candidate compensation schemes by selecting compensators with different installation parameters and presetting different installation distances.

[0155] The installation distance may refer to an installation interval distance between compensators. For example, the installation distance may be 100 meters, 50 meters, 10 meters, etc.

[0156] The second candidate compensation scheme may refer to a scheme that includes the installation distance and may be a final compensation scheme.

[0157] In some embodiments, the smart gas device management platform 130 may generate the plurality of sets of second candidate compensation schemes by selecting a plurality of compensators with different installation parameters and presetting a plurality of different installation distances for the compensators with different installation parameters. The compensator with each set of installation parameters and an installation distance may correspond to a set of second candidate compensation schemes. For example, the smart gas device management platform 130 may generate the plurality of sets of second candidate compensation schemes by randomly combining a plurality of compensators with different installation quantities, different installation locations, different device parameters (e.g., a material, a count of corrugations, a wave interval, a wall thickness), and different installation distances.

[0158] In some embodiments, the smart gas device management platform 130 may preset, based on a first candidate compensation scheme, the different installation distance for the compensator to generate the second candidate compensation scheme.

[0159] In step 720, for each set of second candidate compensation schemes, calculating the estimated compensation performance of each compensator at an interval of the installation distance corresponding to the second candidate compensation scheme, wherein the estimated compensation performance is determined based on a second estimated stretching and contracting amount sequence of the target pipeline subsection connected to both ends of the compensator.

[0160] The smart gas equipment management platform 130 may, for each set of second candidate compensation schemes, determine a compensation feature of each compensator at an interval of the corresponding installation distance based on the second estimated stretching and contracting amount sequence of the target pipeline subsection at both ends of each interval. The compensation feature of the compensator may be determined based on the second estimated stretching and contracting amount sequence of the target pipeline subsection in a same way that the compensation feature of the compensator is determined based on the estimated stretching and contracting amount of the target pipeline. Further description may be found in the operation 620 of FIG. 6 and the related description thereof, which will not be repeated herein.

[0161] In some embodiments, the smart gas device management platform 130 may determine the compensation performance of the compensator based on the compensation feature of the compensator. The specific determination may be found in the operation 620 of FIG. 6 and the related description thereof, which will not be repeated herein.

[0162] In some embodiments, the second estimated stretching and contracting amount sequence may be determined based on a stretching and contracting amount sequence model. In some embodiments, the smart gas device management platform 130 may input a pipeline feature, an estimated operation feature, and a second temperature sequence of the target pipeline subsection into the stretching and contracting amount sequence model and output the second estimated stretching and contracting amount sequence. The stretching and contracting amount sequence model may be a machine learning model.

[0163] In some embodiments, the second temperature sequence of the target pipeline subsection may be determined by a second gas temperature sequence, a second environmental temperature sequence, and a medium feature of the target pipeline subsection. In some embodiments, the second gas temperature sequence of the target pipeline subsection may be related to a gas transportation direction and a gas transportation distance of the target pipeline subsection. Therefore, an input of the stretching and contracting amount sequence model may also include the gas transportation direction and the gas transportation distance of the target pipeline subsection, the second environmental temperature sequence corresponding to the target pipeline subsection, the medium feature of the target pipeline subsection, and the second temperature sequence of the target pipelines subsection adjacent to each target pipeline subsection. Further description regarding the gas transportation direction and the gas transportation distance of the target pipeline subsection may be found in FIG. 5 and the related description thereof.

[0164] In some embodiments, the stretching and contracting amount sequence model may include a Deep Neural Networks (DNN) model, a Recurrent Neural Networks (RNN) model, other custom networks model, or any combination thereof.

[0165] FIG. 8 is an exemplary schematic diagram illustrating determining of a second estimated stretching and contracting amount sequence based on a stretching and contracting amount sequence model according to some embodiments of the present disclosure.

[0166] As shown in FIG. 8, an input of a stretching and contracting amount sequence model 840 may include a pipeline feature 810, an estimated operation feature 820, and a second temperature sequence 830 of a target pipeline subsection. An output of the stretching and contracting amount sequence model 840 may be the second estimated stretching and contracting amount sequence 850 of the target pipeline subsection. Further description regarding the pipeline feature and the estimated operation feature may be found in FIG. 2 and the related description thereof. Further description regarding the second temperature sequence of the target pipeline subsection corresponding to each preset scenario may be found in FIG. 4 and the related description thereof. Further description regarding the second estimated stretching and contracting amount sequence may be found in FIG. 2 and the related description thereof.

[0167] In some embodiments, the stretching and contracting amount sequence model 840 may be obtained by training.

[0168] In some embodiments, a second training sample for training the stretching and contracting amount sequence model 840 may be simulation experiment data, including a sample pipeline feature, a sample operation feature, and a sample second temperature sequence of the target pipeline subsection corresponding to each preset scenario. The second training sample may be obtained by performing a simulation experiment. For example, a preset pipeline feature may be served as the sample pipeline feature when the simulation experiment is performed. The operation feature and the second temperature sequence may be obtained as the sample operation feature and the sample second temperature sequence when the target pipeline subsection is simulated to operate in the plurality of preset scenarios.

[0169] In some embodiments, a second training label for training the stretching and contracting amount sequence model 840 may be the second estimated stretching and contracting amount sequence corresponding to each set of second training sample when the simulation experiment is performed. The second training label may be obtained by actual measurement when the simulation experiment is performed.

[0170] In some embodiments, the smart gas device management platform 130 may input the second training sample into an initial stretching and contracting amount sequence model to obtain an initial second estimated stretching and contracting amount sequence, construct a loss function based on the initial second estimated stretching and contracting amount sequence and the second training label, and obtain a trained stretching and contracting amount sequence model by updating a parameter of the initial stretching and contracting amount sequence model based on the loss function.

[0171] In some embodiments of the present disclosure, the self-learning capability of the machine learning model may be used to obtain a relationship between the pipeline feature, the estimated operation feature, and the temperature of target pipeline subsection corresponding to each preset scenario and the stretching and contracting amount of the target pipeline subsection by processing the pipeline feature, the estimated operation feature, and the second temperature sequence of the target pipeline subsection corresponding to each preset scenario using the stretching and contracting amount sequence model, so that the data processing efficiency and the accuracy of determining the second estimated stretching and contracting amount sequence can be improved.

[0172] In step 730, determining a second compensation scheme based on the estimated compensation performance and determining the installation distance of the compensator based on the second compensation scheme.

[0173] In some embodiments, the smart gas device management platform 130 may determine a second candidate compensation scheme based on the estimated compensation performance. The specific manner for determining the second candidate compensation scheme may be the same as a manner for determining an optimal first compensation scheme, which may be found in FIG. 6, the operation 630, and the related description thereof and will not be repeated herein.

[0174] In some embodiments of the present disclosure, the second compensation scheme may be determined based on the compensation performance by determining a plurality of candidate compensation schemes and determining the compensation performance of the compensator of each set of second candidate compensation schemes and then the corresponding installation distance may be determined based on the second compensation scheme. In this way, a more suitable installation distance for the compensator can be further determined based on the first compensation scheme, and the reasonableness of the installation parameter of the compensator can be improved.

[0177] The beneficial effects brought about by the embodiments of the present disclosure may include, but are not limited to: (1) By estimating the possible stretching and contracting feature of the target pipeline in advance and determining the appropriate compensator installation scheme based on the stretching and contracting feature, inadequate compensation or excessive compensation of the gas pipeline (resulting in waste of resources) caused by blind installation of compensators can be avoided, and at the same time the influence of the feature of the target pipeline and future operating environmental feature on the stretching and contracting amount of the gas pipeline can be considered, thereby determining the installation parameter of the compensator more accurately and reasonably, improving the effectiveness of installation of the gas pipeline compensator, and increasing the service life of the gas pipeline; (2) the final stretching and contracting amount feature of the target pipeline may be determined by dividing the target pipeline into the plurality of target pipeline subsections and respectively determining the second estimated stretching and contracting amount sequence of each target pipeline subsection, which considers the differences in environmental temperature and gas temperature of different target pipeline subsections and makes the determined stretching and contracting amount feature of the target pipeline more accurate; and (3) the optimal compensation scheme may be determined by selecting the candidate compensation schemes and based on the compensation performance of the compensator in each candidate compensation scheme and then the installation parameter may be determined according to the optimal first compensation scheme. The reasonableness and effectiveness of the determined compensation scheme can be improved by selecting the optimal compensation scheme in the plurality of possible compensation schemes that are designed.
