[Prior art] ′ At the oil depot, the lorry driver looks at the refueling slip with refueling data printed on it, refuels each hatch of the lorry with various types of oil, such as regular gasoline, high-octane gasoline, kerosene, etc. The oil from each hatch is unloaded into an underground tank.

It is fine if the lorry driver refuels each hatch with the same oil as shown on the refueling slip without making any mistakes at the oil depot, but if he refuels with the wrong type of oil, the wrong oil may be unloaded into the underground tank at the refueling station. I will do it.

The oil mixed in this way was not only dangerous but also unusable, resulting in a large loss.

[Object of the Invention] Therefore, the object of the present invention is to provide a hatch identification device for use in, for example, an oil depot to prevent each hatch of a row row from being refueled with oil other than the type of oil that is the same as that on the refueling slip. It is in.

[Structure of the Invention] The hatch identification device according to the present invention includes a detection target provided for each row hatch and a detector provided for each liquid supply system.

[Operations and Effects of the Invention] Therefore, when supplying liquid, the device to be detected is connected to the detector,
A liquid supply permission signal is output only when the signal from the detector is the same as the liquid supply data, and if it is different, a liquid supply permission signal is not output, so each hatch must contain the same liquid type as the liquid supply slip. is supplied.

Therefore, there is no need to unload different liquids, and there is no possibility of mixing liquids.

[Preferred Embodiment] When the present invention is carried out, for example, in an oil depot, the detector is installed on the loading arm, the detection target is installed near the hatch opening, and one of them is attached via a flexible wire, which facilitates the connection operation. It is easy to operate and there is no error in operation. In particular, if the device to be detected is provided near the hatch opening via a flexible wire and the detector is fixed to the loading arm, damage to the circuit of the detector or the like can prevent disconnection of the cable connected to the detector.

[Example] The present invention will be described in detail below with reference to the drawings.

b supplies regular gasoline, and refueling system 2C supplies kerosene.

Each loading arm 6 has a start switch SW connected to the local computer RC.
and a detector 20 are provided.

In the figure, numeral 12 is a flow meter, and 13 is a control valve. As is well known, the tank 7 of the lorry 5 is divided into a plurality of hatches 8a to 8d, and a detection device 30 is attached via a string 33 to the vicinity of the hatch opening into which the loading arm 6 of each hatch 8 is inserted. , these detectors 20 and the detected tool 30 constitute a hatch identification device. (In the drawing, the detected tool 30b of the hatch 8b is the detector 20b of the oil supply system 2b.
It is shown connected to. ) A control bag @ (local computer) RC for preventing incorrect refueling with a card reader 11 for checking the vehicle number of the lorry 5 and operation buttons is provided at a proper place on the rack 1, and a ground connector 10 and a card reader. 11 is connected to a local computer RC.

On the other hand, an IIJ control device (host computer) HC that manages the entire oil depot is installed in an office O located away from the rack 1, and a local computer RC is connected to the host computer HC via a line L. . The host computer HC has a display 14, input buttons 15, a printer 16, an external storage device F, and the like.

Next, the operation will be explained.

The host computer HC installed in the office O aggregates and stores the refueling data entered through the keyboard 15, and issues the refueling slip 31 from the printer 16 on which the refueling data shown in FIG. 4 is printed. This slip 31 includes the car number of the roller, the type of oil for each hatch, and the load. The lorry 5 that came to the oil depot takes the refueling 1 slip 31 at the office O, stops at the refueling area of the rack 1, and connects the ground connector 1.
Connect 0 and insert the special card for Loli 5 into card reader 1.
1, the card data transmitting means 21 of the local computer RC provided on the rack 1 transmits the ground signal connected to the ground 10 (step 81) and the card reader 1.
The host computer HC receives the card reading signal from 1 (step 82) and outputs the card data signal such as the car number written on the card to the host computer HC via the transmitting/receiving means 34 (step S3). Upon receiving this signal, the refueling data for the vehicle number is output. The local computer RC receives the refueling data in step S.
4), stored in the storage means 22 (step 35).

Next, the operator inserts the loading arm 6 into the hatch 8 by looking at the refueling slip, and connects the detected tool 30 to the detector 20. The oil type signal of the arm is input to the local computer RC2 (step S6), and the oil supply data stored in the storage means 22 and the determination means 23 are input.
It is determined whether the loading arm of the correct oil type is pressed to the correct hatch (step 87).
. If it is incorrect, issue a notification signal (step S8),
The alarm 35 is activated. If correct, refueling permission means 2
4 issues a refueling permission signal to the refueling system control means 32 (step 89).

The corresponding refueling system receives this refueling permission signal and becomes ready for refueling. Next, when the start switch SW is pressed, the control valve 12 is opened by the action of the oil supply system control means 32, oil is supplied, and the flow rate signal from the flow meter 13 is displayed on the display section 3 and stored in the storage means 22. When the fuel is supplied to the specified amount, the control valve 12 is closed, and the fuel supply system ends (step 511). The refueling completion determining means 36 determines whether refueling for all refueling data has been completed (step 512), and if not, it waits for the next refueling to end. The operator refuels another hatch using the same operation as described above. When refueling for all refueling data has been completed (step 512), the refueling completion determination means 36 outputs a refueling completion signal to the host computer HC (step 313). Upon receiving this refueling completion signal, the host computer: The refueling data for the vehicle number is classified and stored in the external storage bag @F, and all refueling processing is completed.
