Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle movement detection device that is installed at a gasoline filling station or the like where gasoline is refueled for vehicles or the like.

[Conventional technology and its problems]

At a gasoline filling station, a car that is being refueled starts, causing the refueling nozzle to come off the car's refueling port, spreading gasoline around, creating a fire hazard, or damaging the refueling nozzle or refueling hose. In order to prevent
Multiple vehicle detectors are buried in the refueling area, and a control device compares the vehicle detection signals of all the detectors at the start of refueling with the vehicle detection signals of all the detectors during refueling, and notifies you if there is a change. There is something to do.

[Problem that the invention seeks to solve]

However, in the conventional method, the signals of all the detectors are constantly checked, so the function of the control device becomes large and expensive.

Another problem was that if another car approached while refueling, a detection signal would be generated from the detector that did not detect the car at the time of refueling, and the control device would conclude that the car being refueled had moved. .

The purpose of the present invention is to solve the disadvantages of the conventional example, and to provide an inexpensive vehicle movement detection system that is capable of notifying when a vehicle is refueling and starts moving to ensure the safety of a gas station, and that is inexpensive and free from the risk of false detection. The goal is to provide equipment.

[Means for solving problems]

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

[Effect]

According to the present invention, when a vehicle stops at a refueling area for refueling, a signal is output from one of the detectors installed in the refueling area located below the vehicle. If a signal is output from the same location while refueling, it is determined that the vehicle has not moved, and if the signal changes, the alarm is activated to notify that the vehicle has moved.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an overall perspective view showing an embodiment of the vehicle movement detection device of the present invention, in which the vehicle movement detection device of the present invention is installed at a fueling station equipped with a ground-fixed fueling device.

First, to explain the overall structure of the refueling system, as is well known in the past, a refueling machine case 2 is installed upright on an island 1 installed on the ground, and an underground refueling tank (not shown) is placed inside the refueling machine case 2. ), and a refueling pump 5 connected to a pump motor 4 in the middle of this refueling pipe 3,
Flowmeters 7 to which flow rate pulse transmitters 6 are connected are sequentially arranged.

Then, lead out the end of the fuel supply pipe 3 to the outside of the fuel supply machine case 2,
A refueling hose 9 having a refueling nozzle 8 at the tip is connected here, and a nozzle hook 10 formed on the side of the refueling machine case 2 is connected here.
A nozzle switch 11 that is turned on and off in conjunction with the hooking and unhooking of the refueling nozzle 8 is provided. Further, 12 in the figure indicates an indicator for the amount of oil to be supplied, etc.

The present invention includes vehicle detectors 13a, 13b, 13c, . . . 13 for detecting the presence of a vehicle in the fueling area A formed on the ground in front of the fueling device configured as described above.
A plurality of ``n'' were buried, for example, in two rows at appropriate intervals.

The automobile detector 13 may be an ultrasonic type detector, a metal detection type detector, or the like.

Further, an alarm 14 is provided on the top surface of the fuel dispenser case 2, etc., and a notification stop switch 21 is provided on the side surface of the fuel dispenser case 2.

In this way, a control device 15 using a microcomputer or the like is arranged inside the fuel dispenser case 2, and as shown in the block diagram of FIG. 2, the nozzle switch 11, the vehicle detector 13a,
13b, 13c, =43n, flow rate pulse transmitter 6,
The output signal from the notification stop switch 21 is introduced into the control device 15, and the control signal from the control device 15 is transmitted to the display 12,
It was introduced into the pump motor 4 and the alarm 14. As is conventionally known, this control device 15 includes a central processing unit 16, an input/output device 17, and a memory value! (RAM) 1B, storage device (ROM)

, 13b, 13c.

...Among 13n, those located below the stopped car, for example, 13a, 13b, 13c, 13d
The four detectors detect the presence of a car, and the detection signals are input to the control device 15, which stores which detector is outputting the detection signal. At the same time, the pump motor 4 starts rotating and the oil supply pump 5 is driven (steps).

In this way, the refueling nozzle 8 is inserted into the refueling port of the car to refuel, and when the gasoline tank is full, the refueling nozzle 8
When the pump is removed from the refueling port and returned to the nozzle hook 10, the nozzle switch 11 is turned off (step 1), and a signal is input to the control device 15, which stops the pump motor 4 and ends the refueling (step 10). ).

By the way, during refueling, if the car moves due to a misunderstanding that refueling has finished, a signal from one of the car detectors 13a to 13n, for example 1.3C and 13d, stored when the nozzle switch 11 was turned on is detected. starts to disappear. When there is such a signal change (to step), that is, when the car moves during refueling, the pump motor 4 is stopped by the output from the control device 15, the refueling pump 5 is stopped (step), and refueling is stopped midway. When the vehicle stops, the alarm 14 is activated (Snapatch) to notify with light and sound that the vehicle has moved.

As a result, the gas station worker urges the driver to stop the vehicle, or the driver or the like stops moving the vehicle, knowing that refueling has not yet been completed. After confirming safety, press the notification stop switch 21 (
Stellar Pr), the alarm 14 is stopped, and the control device 15 re-memorizes the detector from which the detection signal is output (Step C).

Then, when refueling is resumed and refueling is finished, the refueling nozzle 8 is pulled out from the fuel filler port of the car, and this is inserted into the nozzle hook 1.
If you return it to 0, the nozzle switch 11 will turn off.)
, the pump motor 4 stops and oil supply ends (snap-off).

〔Effect of the invention〕

As described above, the vehicle movement detection device of the present invention notifies you immediately when a vehicle moves during refueling, so there is no risk of overlooking the movement even if you are doing other work while refueling, Safety can be ensured.

In addition, among the multiple detectors installed in the refueling area, only the one that detects the car at the start of refueling is checked during refueling, so the control device's functionality can be small, and even if another car enters the refueling area. It is something that will not malfunction even if it is entered.
