The leaving-propriety indicating unit may be provided at a leaving area of a gas station to which the fueling system of the present invention is installed, in order to appropriately indicate if the car has been fueled with the payment for fueling accomplished or not. The leaving-propriety indicating unit eliminates the possible destruction of the fueling system caused by a car started while fueling.
Other features of this invention will become apparent in the course of the following description of exemplary embodiments, which are given for illustration of the invention and are not intended to be limiting thereof.
The fueling system of the present invention will now be explained by referring to FIG. 1, which is a schematic top view of a gas station with the fueling system, to clearly show the general flow of the operations together with explaining constituents of the system.
A plurality islands M, M are provided in the gas station for supplying several kinds of fuel to automobiles, and entry area 1, fueling area 2, and leaving area 3 are successively formed at the sides of island M. A fueling guide display unit 4 is provided on the top of the island M as to face the entry area 1; fueling units 5, on the middle thereof which faces the fueling area 2; and leaving-propriety indicating units 6, on the rear end which faces the leaving area 3.
Inside an office N, there are provided a liquidation machine 7 and an indoor fueling state indicator 8. Furthermore, an outdoor fueling state indicator 9 is provided at a part which can be seen from every fueling area 2, for instance on the wall of the office N.
FIG. 2 shows details about each of the island M, that is, a perspective view for explaining constituents of the fueling system and the relationship therebetween. The fueling unit 5 and liquidation machine 7 are connected to each other via a signal conductor 10; the liquidation machine 7 and the indoor fueling state indicator 8 are connected to each other by means of a signal conductor 11; and the indoor fueling state indicator 8, outdoor fueling state indicator 9 and leaving-propriety indicating units 6 are connected via a signal conductor 12.
The fueling guide display unit 4 provided on the island at a top part thereof facing the entry area 1 is composed of a pair of supporting posts 4a, a case 4b adjusted onto the posts 4a, and guide panels 4c adjusted to the front surface of the case 4c. The kinds of fuel available are shown as "H (high octane), R (regular), D (Diesel), or greetings such as "Welcome" are displayed on the guide panels 4c.
Three kinds of fuel, for instance, regular gasoline, high octane gasoline and diesel fuel are incorporated in the fueling unit 5 and two fueling units 5 are contained in a single casing 5J in FIG. 2. Here, the fueling unit 5 is also provided on the central part of the island M, facing the fueling area 2. Pumps 5b and flow meters 5c are connected to fueling tubes 5a in each fueling unit 5. Each of the fueling tubes is connected to a fueling hose 5e with a fueling nozzle 5d at the tip thereof. A nozzle switch 5g for detecting the putting on and off of the nozzle 5d is provided on each of the nozzle rests 5f for the fueling nozzle 5d.
When a nozzle putting off signal from the nozzle switch 5g showing the nozzle being put off the nozzle rest 5f and a flow-volume signal from the flow-meter 5c are input to a fueling-unit control part 5h, the control part 5h brings the indicate numbers of the previous fuel amount shown in a fuel amount indicator 5i to zero, outputs a drive signal to the pump 5b, and displays the supplied fuel amount to the fuel amount indicator 5i which has been obtained by the calculation based on the flow-volume signal. Thereafter, the control part 5h de-energizes the drive signal to the pump 5b, receiving the nozzle putting on signal from the nozzle switch 5g. As is described below, the control part 5h outputs a fueling start signal when received the nozzle putting off signal a fueling completion signal by receiving the nozzle putting off signal from the nozzle switch 5g, and the output signals are transmitted to the liquidation machine 7. In addition, the control part 5h receives the flow-volume signal from the flow-meter 5c, which is output to the liquidation machine 7.
The leaving-propriety indicating unit 6 provided on the island M at the rear top thereof facing the leaving area 3 is composed of a support post 6a fixed onto the island M, a main body casing 6b adjusted to the top of the support post 6a, and an indicating member 6c. The indicating member 6c is to be fixed in a leaving possible position A with the indicating member 6c hung down and in a leaving impossible position B with the indicating member 6c made horizontal by the rotation of 90.degree. C. by a reversible motor (not shown) provided in the main body casing 6b. Here, the reference symbols A and B are shown with an arrow in FIG. 2. More precisely, the reversible motor causes the indicating member 6c to move from the leaving possible position A to the leaving impossible position B when "ON" signal is input by a pressing switch 6d provided on the main body casing 6b pressed, and from the leaving impossible position B to the leaving possible position A in the case of receiving a liquidation completion signal from the indoor fueling state indicator 8 as is described below.
A so-called POS terminal can be employed as a liquidation machine 7 in the office N. A liquidation-machine control part 7a starts to control fueling data of the fueling units 5 by receiving the fueling start signal therefrom, and converts the flow-volume signal to numbers. Thereafter, a fueling slip, on which the converted fueling data is printed, is issued from a printer 7d when the issuing key 7c on a keyboard 7b of the liquidation machine 7 is pressed. Moreover, a fueling signal is output when the flow-volume signal is input from the fueling unit 5, a fueling suspension signal is output when the flow-volume signal is suspended, and the fueling completion signal is output when the fueling completion signal is input, each to the indoor fueling state indicator 8. When the issuing key 7c is pressed, the liquidation completion signal is output to the leaving-propriety indicating unit 6.
The indoor fueling state indicator 8 placed in the office N is composed of a main body casing 8a, fueling unit-numbers 8b indicated in the front surface of the main body casing 8a, indoor indication lamps 8c provided so as to correspond to fueling unit-numbers 8b, an indoor communicator 8d, and a control part 8e. The control part 8e which receives the fueling completion signal causes a corresponding indication lamp to be turned on and off, and the communicator 8d to ring. By the receipt of the liquidation completion signal, the control part 8e causes the indication lamps to be turned off. The control part 8e outputs the fueling signal, fueling suspension signal, and fueling completion signal to the outdoor fueling state indicator 9. The liquidation completion signal is also output from the control part 8e to the leaving-propriety indicating unit 6, when the control part 8e receives the liquidation completion signal.
The outdoor fueling state indicator 9, which is provided at a place visible from each fueling area 2, such as outer wall of the office N, is composed of a main body casing 9a, fueling unit-numbers 9b indicated on the front surface of the main body casing 9a, outdoor indication lamps 9c correspondingly provided to the fueling unit-numbers 9b, outdoor communicator 9d, and outdoor-fueling-state-indicator control part 9e. The control part 9e causes the indication lamp 9c to be turned on with the receipt of the fueling signal from the indoor fueling state indicator 8, causes the lamp 9c to be turned on and off with the communicator 9d being rung by the receipt of the fueling suspension signal, and caused the lamp 9c to be turned off when the fueling completion signal is received. It is preferable that each of the fueling units 5 have a fueling unit lamp 5K on the casing 5J, which acts in the same way as the outdoor indication lamp 9c, for showing the fueling state to people nearby the fueling unit 5.
The operation of the fueling system of the present invention will now be described.
First of all, when there is no car in the gas station, the indicator 6c of the leaving-propriety indicating unit 6 is hung down, which is in the leaving possible position A kept drawn seen from the leaving area 3 side. In this case, indication lamps 8c and 9c are off.
A customer arriving at the gas station for fueling first drives from the entry area 1 where a desired kind of fuel is indicated on the guide panel 4c to the fueling area 2 and stops the car therein. When a car stopped at the fueling area 2 is observed, an operator of the gas station presses the pressing switch 6d of the leaving-propriety indicating unit 6, the indicating member 6c in the hung down state, that is leaving possible position A, rotates to be horizontal in the leaving impossible position B. Thus, the indicating member 6c of the leaving-propriety indicating unit 6 protrudes to the leaving area 3 with the indication of leaving impossibility thereon, so that the customer never starts the car by mistake while fuel is being fed.
The operation of the control parts 5h, 7a and 8e of the fueling unit 5, liquidation machine 7, and indoor fueling state indicator 8 will now be explained with referring to the flow-charts shown as FIGS. 3 to 5.
As a fueling nozzle 5d of the desired kind of fuel is detached from the nozzle rest 5f, a nozzle putting off signal is output from the nozzle switch 5g to the control part 5h (FIG. 3, ST1). Then, the control part 5h brings the number indicated on the fuel amount indicator 5i, which is the amount of fuel fed by the previous feeding, to zero and outputs a drive signal to a pump 5b, and a fueling start signal to the liquidation machine 7 (FIG. 3, ST2) Accordingly, the pump 5bis started to drive. When the fueling nozzle 5d is inserted to a fueling port of the car and the fueling is started with the valve of the fueling nozzle 5d open, the flow-volume signal is input from the flow meter 5c to the control part 5h (FIG. 3, ST3), the fueled amount is indicated to the fuel amount indicator 5i with the flow-volume signal converted to the fueled amount as numbers, and the flow-volume signal is output to the liquidation machine 7 (FIG. 3, ST4).
When, when the fueling start signal is received by the liquidation-machine control part 7a (FIG. 4, ST1), the control part 7a begins to control fueling data of the fueling unit 5 (FIG. 4, ST2). Then, the flow-volume signal is input to the control part 7a (FIG. 4, ST3), the flow-volume signal is converted, the fueling signal is output to the indoor fueling state indicator 8, and the counter, which is explained below, is reset (FIG. 4, ST4).
As the fueling signal is input from the liquidation machine 7 to the indoor fueling state indicator 8 (FIG. 5, ST1), the indication lamp 8c is turned on and the fueling signal is output to the outdoor fueling state indicator 9 (FIG. 4, ST2). The control part 9e of the outdoor fueling state indicator 9 turns on the corresponding indication lamp 9c to the fueling unit 5 by receiving the fueling signal.
Thus, fueling progresses, and the fuel tank of the car is almost filled up. In this state, fueling is suspended by the liquid level being detected. Accordingly, the input of the flow-volume signal from the fueling unit 5 to the liquidation machine 7 is stopped (FIG. 4, ST3), and then a counter for counting the fueling suspension time is set (FIG. 4, ST5). If the fueling suspension time continues for a predetermined period, for instance 3 seconds or more, the counter counts up (FIG. 4, ST6), and the control part 7a of the liquidation machine 7 outputs the fueling suspension signal to the outdoor fueling state indicator 8 (FIG. 4 T7). The control part 8e which has received the fueling suspension signal (FIG. 5, ST3) outputs the fueling suspension signal to the outdoor fueling state indicator 9 (FIG. 5, ST4), whereby the control part 9e of the outdoor fueling state indicator 9 causes the indication lamp 9c to be turned on an off, and the communicator 9d to ring.
As is explained above, a fueling operator while doing other operations can notice the fueling suspension of the fueling because of the outdoor indication lamp 9e which turns on and off and the sound of the outdoor communicator 9d. Then, the fueling operator opens the valve of the fueling nozzle 5d again to add some fuel to the fueling tank of the car in order to fill make the tank completely with fuel.
When the fueling operator opens the valve of the fueling nozzle 5d as mentioned above, a flow-volume signal is input from the fueling unit 5 to the liquidation machine 7 (FIG. 4, ST3), a fueling signal is output to the indoor fueling state indicator 8, and the counter for counting the fueling suspension period is reset (FIG. 4, ST4). Thereafter, the indoor fueling state indicator 8 which has received the fueling signal (FIG. 5, ST5) outputs the fueling signal to the outdoor fueling state indicator 9 (FIG. 5, ST6), so that the indication lamp 9c of the outdoor fueling state indicator 9 is turned on again.
As the fuel tank of the car is filled with fuel in accordance with the above-mentioned procedure, the fueling nozzle 5d is hung on the nozzle rest 5f and the nozzle switch 5g outputs nozzle hung signal to the fueling unit 5 (FIG. 3, ST5). Responding this, the control part 5h of the fueling unit 5 de-energizes the drive signal for the pump 5b, whereby fueling completion signal is output to the liquidation machine 7 (FIG. 3, ST6). Following the receipt of the fueling completion signal by the control part 7a of the liquidation machine 7 (FIG. 4, ST8), the fueling completion signal is output to the indoor fueling state indicator 8 (FIG. 4, ST9). The indoor fueling state indicator 8 which has received the fueling completion signal (FIG. 5, ST7) rings the communicator 8d under turning the indication lamp 8c on and off, and then the fueling completion signal is output to the outdoor fueling state indicator 9 (FIG. 5, ST8). The outdoor fueling state indicator 9 having received the fueling completion signal turns off the indication lamp 9c.
By the sound of communicator 8d and the indication lamp 8c turning on and off, a settling clerk notices the end of fueling and can settles an account right away. Here, the customer comes into the office N to pay money for fueling by himself. Where a issuing key 7c of the liquidation machine 7 is pressed (FIG. 4, ST10), a fueling slip is issued from a printer 7d, with fueling data being printed thereon. The fueling completion signal is output to the indoor fueling state indicator 8 (FIG. 4, ST11).
The indoor fueling state indicator 8 which has received the liquidation completion signal (FIG. 5, ST9) turns off the indication lamp 8c, and outputs the liquidation completion signal to the leaving-propriety indicating unit 6 (FIG. 5, ST10). By being received the liquidation completion signal, the leaving-propriety indicating unit 6 rotates the indicating member 6c from the leaving impossible position B to leaving possible position A. The car after fueling can leave from the gas station by moving from the fueling area 2 to the leaving area 3 after the indicating member 6c is brought into the position A.
As previously mentioned, if the fueling is completed without additional fueling after the fueling suspension for a predetermined period and the fueling completion signal is input from the fueling unit 5 to the indoor fueling state indicator 8 via a liquidation machine 7 (FIG. 5, ST11), control part 8e of the indoor fueling state indicator 8 causes the indication lamp 8c to be turned on and off, and to output the fueling completion signal to the outdoor fueling state indicator 9 (FIG. 5, ST8), whereby the indication lamp 9c of the outdoor fueling state indicator 9 is turned off.
As is obvious from the above explanations, the fueling system of the invention can be established by employing the conventional liquidation machine such as a POS terminal, of which processing capacity can efficiently be used without the decrease of the processing speed by the fueling system of the present invention wherein the outdoor fueling state indicator 9 is under the control of the indoor fueling state indicator 8.
