Description

Description: TECHNICAL FIELD The present invention relates to a vehicle movement detection device installed in a gasoline filling station for supplying gasoline to an automobile or the like.

[Conventional technology and its problems]

At a gasoline filling station, a car that is being refueled starts and as a result, the refueling nozzle comes off the car's refueling port and gasoline is scattered around, causing a fire hazard or damaging the refueling nozzle or refueling hose. To prevent
By embedding multiple vehicle detectors in the refueling area, the control device compares the vehicle detection signals of all detectors at the start of refueling with the vehicle detection signals of all detectors during refueling, and notifies if there is a change There is something to do.

[Problems to be solved by the invention]

However, in the conventional device, since the signals of all the detectors are constantly checked, the function of the control device becomes large and it is expensive.
Further, when another vehicle approaches during refueling, a detection signal is generated from a detector that does not detect the vehicle during refueling, and the control device has a disadvantage that the refueled vehicle has moved.

The object of the present invention is to eliminate the inconvenience of the above-mentioned conventional example, to notify when the car being refueled starts, to ensure the safety of the gas station, and to detect the movement of the car at a low cost and without the risk of erroneous detection. To provide a device.

[Means for solving problems]

In order to achieve the above object, the present invention stores a plurality of vehicle detectors provided in a refueling area and a detector outputting a vehicle detection signal at the start of refueling, and when the detection signal disappears from the detectors during refueling. The gist of the invention is that it is composed of a control device that outputs a signal and an alarm device that is activated by a signal from the control device.

[Action]

According to the present invention, when the vehicle stops in the refueling area for refueling, a signal is output from one of the detectors installed in the refueling area, which is located below the vehicle. If a signal is output from the same place even during refueling, it is determined that the vehicle has not moved, and if there is a change in the signal, an alarm is activated to notify that the vehicle has moved.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an overall perspective view showing an embodiment of a vehicle movement detecting device of the present invention, in which the vehicle movement detecting device of the present invention is installed in a fueling station provided with a ground-fixing type fueling device.

First, the overall structure of the refueling device will be described. As is well known in the art, a refueling machine case 2 is erected on an eyeliner 1 installed on the ground, and an underground refueling tank (not shown) is provided in the refueling machine case 2. The oil supply pipe 3 that communicates with (1) is started up, and an oil supply pump 5 connected to a pump motor 4 and a flow meter 7 connected to a flow rate pulse transmitter 6 are sequentially arranged in the middle of the oil supply pipe 3. Then, the end of the refueling pipe 3 is led out of the refueling machine case 2, a refueling hose 9 having a refueling nozzle 8 at the tip is connected to the refueling case, and the refueling nozzle is connected to the nozzle hook 10 formed on the side of the refueling machine case 2. A nozzle switch 11 that turns on and off in synchronism with the hanging of 8 is provided. Reference numeral 12 in the figure indicates an indicator for the amount of oil supplied.

In the present invention, a plurality of vehicle detectors 13a, 13b, 13c, ... 13n for detecting the presence of an automobile are appropriately provided in a refueling area A formed on the ground in front of the refueling device thus configured, for example, in two rows. Buried at intervals. The vehicle detector 13 may be an ultrasonic detector, a metal detector, or the like.

Further, an alarm 14 is provided on the upper surface of the refueling machine case 2 to notify the movement of the automobile during refueling by light or sound, and a notification stop switch 21 is provided on the side surface of the refueling machine case 2 or the like.

In this way, the control device 15 using a microcomputer or the like is arranged in the refueling machine case 2, and the nozzle switch 11, vehicle detectors 13a, 13b, 13c, ... As shown in the block diagram of FIG.
Output signals from 13n, the flow pulse generator 6 and the alarm stop switch 21 were introduced into the control device 15, and the control signals from the control device 15 were introduced into the display device 12, the pump motor 4 and the alarm device 14. The controller 15 is a central processing unit as is well known in the art.
16, input / output device 17, storage device (RAM) 18, storage device (RO
M) 19 and clock circuit 20.

Next, the operation will be described with reference to the flowchart of FIG. 3. When the vehicle stops in the refueling area A for refueling and the refueling nozzle 8 is removed from the nozzle hook 10, the nozzle switch 11 is turned on (step a), and the nozzle is removed. Signal is control device
Enter 15. As a result, the previous refueling amount displayed on the display unit 12 is reset to zero (step B), and a plurality of vehicle detectors 13a, 13b, 13c, ... 13 installed in the refueling area A are installed.
Of c, those located below the stopped car, for example, four of 13a, 13b, 13c, 13d detect the existence of the car,
The detection signal is input to the control device 15, and which detector outputs the detection signal is stored. At the same time, the pump motor 4 starts rotating and the oil supply pump 5 is driven (step C).

In this way, the refueling nozzle 5 is inserted into the refueling port of the automobile to refuel, and the gasoline tank becomes full and the refueling nozzle 8
When the oil is removed from the oil supply port and returned to the nozzle hook 10, the nozzle switch 11 is turned off (step D), the nozzle hook signal is input to the control device 15, and the pump motor 4 is stopped by this and the oil supply is completed (step H). ).

By the way, during refueling, when the car moves by misidentifying that refueling has ended, etc., one of the car detectors 13a to 13n stored when the nozzle switch 11 is turned on, for example,
The signals from 13c and 13d will disappear. When there is such a signal change (to step), that is, when the vehicle moves during refueling, the pump motor 4 is stopped by the output from the control device 15 and the refueling pump 5 is stopped (step),
The refueling stops halfway, and the alarm 14 operates (steps) to notify by light or sound that the car has moved.

As a result, the operator of the gas station prompts the driver to stop the vehicle, or stops the movement of the vehicle when he / she knows that the fueling has not been completed yet. Then, if safety is confirmed and the notification stop switch 21 is pressed (step), the alarm 14 is stopped, and the control device 15 stores the detector outputting the detection signal again (step C).

Then, when refueling is restarted and the refueling is finished, the refueling nozzle 8 is pulled out from the refueling port of the automobile, and the refueling nozzle 8 is connected to the nozzle 10
Then, the nozzle switch 11 is turned off (step 2), the pump motor 4 is stopped, and refueling is completed (snap ho).

〔The invention's effect〕

As described above, the vehicle movement detection device of the present invention notifies this immediately when the vehicle moves during refueling, so there is no risk of overlooking this even if other work is being performed during refueling. You can secure safety.

Also, of the multiple detectors provided in the refueling area, only the one that detects the vehicle at the start of refueling is checked during refueling, so the function of the control device may be small, and another vehicle may be placed in the refueling area. Even if it enters, it does not malfunction.
