Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring device for a plurality of refueling machines at a service station for refueling gasoline or other fuel to an automobile or the like.

[Conventional technology and its problems]

When a plurality of refueling machines are provided at such a gas station, especially if they are self-service type and operated by the customer, it is necessary to have a system capable of collectively monitoring all of the refueling machines.

Conventionally, an indicator lamp is provided in the office of the gas station, and each refueling machine is indicated by the lighting state of each lamp. It is only possible to know the amount of refueling and other information.

Also, as is often done in supermarkets and other places, it is conceivable to install a TV camera on the canopy of the gas station and display the entire gas station on the screen on the screen, but this will still display specific information such as the amount of fuel. It is not possible, and it is possible that the state of the refueling machine is inadequate in the long-distance determination by the camera.

An object of the present invention is to solve the above-mentioned inconveniences and provide a highly accurate gas station monitoring device with good workability.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention connects a flow rate pulse transmitter attached to a nozzle switch and a flow meter, which is operated by hooking and unplugging a fueling nozzle provided in each fuel dispenser, to a control device, and The output signal from this control device is introduced into the pump motor that drives the refueling pump, and the refueling state detection means is formed in the control section of the control device.
The control unit is a large CR so that the key for refueling permission and the information of each refueling machine can be displayed collectively in different areas.
The T display screen is connected, and when the refueling state detection means detects that the nozzle has been removed, the control unit of this control device displays a character indicating "refueling request" in the area of the refueling machine on the CRT display screen. When the refueling machine starts refueling based on the refueling permission from the refueling permission means, it displays the character "refueling" and the refueling amount in line with the character, and when the refueling state detection means detects that the nozzle has been applied, The gist of the present invention is to be a control unit for performing display screen control such that a character indicating "refueling completed" is displayed instead of the character indicating "refueling".

[Action]

According to the present invention, the refueling work stage, refueling amount, precautions, etc. for each refueling machine can be collectively displayed on the screen, whereby comprehensive and appropriate monitoring can be performed.

Example of Invention

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

FIG. 1 is a block diagram showing an embodiment of a monitoring device of the present invention,
FIG. 2 is a front view of a display screen which is a main part of the same as above, and FIG. 3 is an external perspective view of a gas station using the device of the present invention, in which 1- (1), 1- (2), 1- ( 3) and 1- (4) are fixed-type ground refueling machines, in which a case with a refueling pump and a flow meter is equipped with a refueling case having a refueling nozzle at the tip so that gasoline, etc. can be measured and sold from underground tanks. It was done like this.

In addition, this refueling machine 1- (1), 1- (2), 1-
Unlike (3) and 1- (4), a vehicle detector 2, an engine stop detector 3, and a speaker 4 are provided, unlike a general refueling machine.

In the figure, 5 is a computer, RAM, ROM, CPU, CLOCK
A control unit of the control device 15 including a printer 6, a floppy disk 7, a keyboard 8 and the like as peripheral devices, and each refueling machine 1- (1), 1- (2), 1-
(3) and 1- (4) are connected to send and receive signals. That is, the output signals from the nozzle switch 10 that operates by unplugging the fueling nozzle of each fuel dispenser from the nozzle hook, the flow rate pulse transmitter 12 attached to the flow meter, the vehicle detector 2, the engine stop detector 3, and the like. The output signal from the control unit 5 is introduced into the control unit 5 of the control unit 15, and the pump motor 11 for driving the oil supply pump and the speaker 4 are introduced.
To be introduced into.

Also, a CRT display screen 9 is connected to the control unit 5, and this screen 9 is for each refueling machine 1- (1), 1- (2), 1- (3),
The information of 1- (4) is made large so that it can be displayed collectively by dividing the area.

Next, the usage and operation will be described based on the flowchart of FIG. 4. When the vehicle enters the gas station, the vehicle detector 2 detects it and the engine stop detector 3 detects the vehicle. When it is confirmed that the vehicle has stopped in front of the refueling machine (step a), the control unit 5 causes the display screen 9 to display that, for example, with the characters "car stopped", and the speaker 4 of the refueling machine displays " Welcome, it's regular gasoline. "

For example, if the refueling nozzle is removed from the nozzle hook in the refueling machine 1- (1), the nozzle switch 10 is turned on (step C), and the output indicates that the "car stopped" is displayed on the display screen 9.
Is erased, and then the word "refueling request" is displayed (step d).

In response to this, if the refueling permission switch on the keyboard 8 of the control device 15 is turned on (step E), the pump motor 11 is turned on by the signal, and the refueling amount indicator 13 of the refueling machine 1- (1) returns to zero. Then, refueling becomes possible. At the same time, the word "refueling" is displayed on the display screen 9 (step S).

If the pump motor 11 is turned on and the refueling nozzle is not opened within a certain time (for example, 30 seconds) and refueling is not started, the display screen 9 prompts “please refuel promptly”.
Is displayed in a blinking state, and the same content is notified from the speaker 4 to the refueling area. This decision is 30
It is performed depending on whether or not a flow rate signal is output from the flow rate pulse transmitter 12 provided in the flow meter within a second (stepped, chi,
Re).

When refueling is started by opening the refueling nozzle within a fixed time, that is, when the flow rate signal is input to the control unit 5, the refueling amount is counted and the refueling amount is displayed on the refueling amount display meter 13 and the display screen 9. During such refueling, the control unit 5 monitors whether the refueling is in progress or the refueling is completed depending on whether or not the flow rate signal is sequentially input and whether or not the refueling nozzle is hung on the nozzle hook. If there is no refueling and there is no refueling, the caution character of "Please refill the nozzle when refueling is finished" is displayed in a blinking state on the display screen 9 and the same content is notified from the speaker 4 (the above steps o, w , Mosquitoes).

When the refueling nozzle is applied and the nozzle switch 10 is turned off, the display screen 9 displays "refueling completed" and the speaker 4
Will give you a guide saying, "The amount of refueling is ○○. Please settle at the office." (Stepyo). Then, when the car starts and the car detector 2 confirms that there is no car (step S), all the work procedures are completed.

As shown in FIG. 2, the display screen 9 displays the refueling information of each refueling machine as described above individually and collectively.

〔The invention's effect〕

As described above, the gas station monitoring device of the present invention, when provided with a plurality of refueling machines, can collectively display the refueling work stage, the refueling amount, or the precautions for each refueling machine on a single screen. It is possible to carry out comprehensive and appropriate monitoring work.
