Description

Technical Field

[0001] The invention relates to the technical field of physical therapy instruments, in particular to a control method and system for physical therapy instruments.

Background Technique

[0002] Physiotherapy equipment generates electrical pulses to stimulate human muscle tissue and nerves to achieve the effects of relaxing muscles, relieving pain and even treating certain diseases. Most of the existing physiotherapy apparatuses combine the control host of the physiotherapy apparatus with electrodes for physiotherapy. By sticking the electrodes on the human body, pulse massage or treatment is performed. Generally, the electrode sheets and the control host of the physiotherapy instrument are connected through electrode wires, but for physiotherapy of different parts of the body, the length of the electrode wires required is different, which brings inconvenience to the user and affects the appearance.

[0003] The combination of wireless communication technology and physiotherapy apparatus makes the physiotherapy apparatus wireless. The control end of the physiotherapy apparatus is divided into two parts. One side is the remote control controlled by the user, which is used to control the intensity of the pulse and the transmission of the signal.

[0004] But the existing physical therapy instrument only allows one massage mode at a time, and does not consider the needs of different massage modes for different parts of the body. In addition, existing physiotherapy instruments usually use Bluetooth connection for wireless connection, but the transmission distance of Bluetooth is short, and the signal stability is poor, and multiple signal interferences are prone to occur during use, and there is also the problem of excessive energy consumption for data transmission. Therefore, a technique is needed to solve the above problems.

Detailed Ways

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] Please refer to FIG. 1, in a kind of preferred embodiment, a kind of physiotherapist control method is applied to physiotherapist, and described physiotherapist comprises remote controller 1, main frame 2 and electrode sheet 3, and described remote controller 1 is connected wirelessly with described host computer 2, and described remote controller 1 is used for transmitting signal remote control described host computer 2;

[0043] The control method of the physical therapy instrument comprises the following steps: When the user needs 3 hosts for massage, take out the host with the first 3 logos and turn it on, and input the number of hosts used after the remote control is turned on.

[0044] S1. The remote controller is connected to the host using 2.4G wireless communication, and the following three channels are used by default: 2416, 2432, and 2464; the remote controller randomly selects a channel as a fixed channel and sends a broadcast command.

[0045] S2. As shown in FIGS. 2 and 3, the host automatically polls all channels, and sequentially sends frequency binding commands to wait for feedback from the remote controller. If a broadcast command from the remote controller is received, the host switches to the corresponding channel and establishes a connection with the remote controller.

[0046] S3. The remote control acquires the parts to be stimulated corresponding to each host, and the user inputs the body parts to be stimulated by the host through the buttons of the remote control or voice input. The body parts available for the remote control include shoulders, waist, joints, thighs and calves.

[0047] Beneficially, the specific steps for the above-mentioned remote controller to obtain the parts to be stimulated corresponding to each host are as follows: after the host is connected to the remote controller, it vibrates sequentially according to the serial number of the host. During the vibration of the host, the user inputs the corresponding site to be stimulated by the button of the remote controller or voice input. After the user inputs the confirmation command, the host stops vibrating, and the next host starts to vibrate until the remote controller obtains the corresponding parts to be stimulated of all hosts;

[0048] Beneficially, the above-mentioned method for the user to input the part to be stimulated corresponding to the main unit by voice is for example: after the main unit is connected to the remote controller, it will vibrate sequentially according to the serial number of the main unit. For example, when the main unit located on the left shoulder is vibrating, the user will say “left shoulder” to the remote control, and after inputting a confirmation command, the main unit will stop vibrating, and the next main unit will start to vibrate until the corresponding relationship between all main units and the parts to be stimulated is obtained.

[0049] Beneficially, the host sends out vibration to remind the user of the body part where the host is located, which simplifies the user's operation and improves the user's experience. S4. According to the part to be stimulated, the remote control obtains the recommended mode, recommended intensity and recommended time corresponding to the current part to be stimulated; the recommended mode, recommended intensity and recommended time are pre-set in the remote control, as shown in Table 1 below.

[0051] In this embodiment, before transmitting data packets corresponding to the recommended mode, recommended strength and recommended time to each host, the size S of the data packet is obtained, and the transmission rate v is adjusted according to the following formula:

[0052]

v = {\begin{matrix} [0.1 α \cdot r_{\max}, r_{\max}] S \geq M \\ S < M \end{matrix} α = \exp (S - M)

[0053] Among them, rmax is the maximum transmission rate, which is the rate factor, M is the data packet threshold, and M depends on the peak value P and the average value A of the data packet generated by each use of the physiotherapy device within a period of time, P={P₁, P₂, P₃, . . . , P_n}, A={A₁, A₂, A₃, . . . , A_n}, the specific formula is:

[0054]

M = \frac{\sum_{i = 1}^{n} A_{i}}{n} + \frac{\sum_{i = 1}^{n} P_{i} - \sum_{i = 1}^{n} A_{i}}{3 n}

n is the number of times the physiotherapy device is used within a period of time. For example, the 4 physiotherapy devices used in the previous month produced 4 peaks and 4 average values. Based on this data, the data packet threshold M is calculated. When the physiotherapy device is used in the current month, each time the data is transmitted, if the data packet size is greater than M, it will be transmitted at the rate, otherwise, it will be transmitted at the rate.

- [0056] S21. The host that receives the broadcast command broadcasts and feeds back the broadcast command and the host machine code of the remote controller, where the broadcast command includes the remote controller identification code and the serial number of the host;
- [0057] S22. When the identification codes of the remote control are consistent, the serial number of the current host of the remote control has been connected;
- [0058] S23. The remote controller sends the serial number of the host computer to establish a connection command;
- [0059] S24. The remote controller issues a connection command;
- [0060] S25, when the identification code of the remote control, the serial number of the main unit and the machine code of the main unit are consistent, the connection between the remote control and the main unit is successful.

[0061] In step S21, the remote controller has received the broadcast feedback from the host. In step S22, the remote controller thinks that the host with this serial number has been connected to the remote controller. In steps S23 and S24, the host confirms the connection with the remote controller.

[0062] In this embodiment, the remote controller is equipped with a display screen for displaying the corresponding mode of the stimulation part and the stimulation part. Before step S5, the display screen displays the recommended mode, recommended strength and recommended time corresponding to the part to be stimulated. The updated mode, time or intensity corresponding to the stimulation site is set as the recommended mode, recommended time or recommended intensity, and then step S5 is executed.

[0063] In this embodiment, the data packet includes a host machine code, a port number, a mode parameter, a time parameter, and an intensity parameter, and the host receiving the data packet parses it to output a corresponding pulse signal.

[0064] In this embodiment, the mode parameters include pulse width, pulse interval, duration, and off time.

[0065] In this embodiment, the remote controller has a built-in voice recognition chip, which is used to recognize the instructions issued by the user, and send data packets to the corresponding hosts. If no execution host is specified, send data packets to all connected hosts.

[0066] In this embodiment, the remote control receives the user's voice wake-up command, and enters the wake-up state after the voice reply. After recognizing the command, the voice reply confirms, and sends a data packet to the host at the corresponding part.

[0067] In a preferred embodiment, the user issues an instruction: pinch the waist, and the remote controller voice replies: OK, the remote controller identifies the host corresponding to the waist, and the host establishes a data connection and then sends a data packet. The data packet includes the mode parameters of the pinch mode, and the waist mode is updated on the display screen.

[0068] In this embodiment, the voice command includes host mode switch, pause, time extension, increase and decrease intensity for corresponding parts and host mode switch, pause, extend time, increase and decrease intensity for all connections.
