When any one of e is opened and the shutoff valve 17 that is normally closed is opened, the oil loaded in the selected hatch portion passes through the shutoff valve 17 and reaches the common pipe portion 18.
The oil that has reached the common pipe section 18 is stored in any of the underground tanks of the gas station, as will be described later. In addition,
A three-way solenoid valve 20 is arranged on the vehicle body portion 19 between the cabin portion 11 and the tank portion 12.
Is controlled by the controller 2 to pneumatically drive the shutoff valve 17 of the common piping section 18 described above.

On the other hand, the gas station has an underground tank as described above, and a gas station identification code section 32 in which the gas station identification code is recorded in the underground tank inlet storage box 31.
Is attached, and oil type code portions 34a to 34c in which codes of oil types stored in the respective underground tanks are recorded are attached to the lids of the underground tank inlets 33a to 33c. The hose 23 is connected to any of the inlets of the underground tank and the outlet 22 of the common pipe portion 18 of the tank truck 1.
And the discharge cock 21 is opened, the oil reaching the common piping 18 is stored in any of the underground tanks.

In this way, various kinds of oil loaded on the tank truck are distributed and stored in each underground tank of the gas station, but in this case, if only relying on artificial confirmation, different oils due to confirmation error or the like may occur. As a result, it takes a long time for the recovery work, and there is a risk of causing a secondary and tertiary accident if the mistake is not noticed.
Therefore, in the present invention, before refueling, the contents of each code part attached to the underground tank of the gas station and the tank part of the tank truck are read by the portable wireless device 5, and the controller 2 compares and matches the match. When the coincidence is confirmed, the opening operation or the opening control of each valve is performed.

Next, FIG. 2 is a block diagram showing a detailed configuration of the present system. In the figure, the portable wireless device 5 is provided with a reset button 5c, an all reset button 5d, a confirmation button 5e, and a display section 5f in addition to the handy terminal 5a and the code reader 5b described above. . Here, the code reader 5b is for reading the code of each relevant part and wirelessly communicating with the transceiver 3 to transmit the relevant code to the controller 2 before unloading the oil into the underground tank of the gas station. Further, the display unit 5f displays the result of the collation determination of each code by the controller 2.

Further, the controller 2 which receives information from the portable wireless device 5 via the transceiver 3 is controlled by the control unit 2a, a shipping information card 7 used when unloading an underground tank of a gas station. Shipping information storage unit 2b that stores information on a tank, a gas station identification code storage unit 2c that stores information on a gas station identification code unit 32, an underground tank oil type code storage unit 2d that stores an underground tank oil type code, and a hatch number code. Of the hatch number code storage unit 2e for storing the number and an output unit 2f for controlling the three-way solenoid valve 20.

Next, the operation of the system configured as described above will be described in detail with reference to the flowcharts shown in FIGS. When the driver of the tank truck 1 arrives at the gas station, the controller 2 of the cabin 11 is turned on and the shipping information card 7 that stores the shipping information about the gas station, that is, the amount and type of the oil to be unloaded. Is inserted into the card reader 4 (step ST1).
As a result, the information on the shipping information card 7 is read by the controller 2 via the card reader 4. in this case,
The control unit 2a of the controller 2 determines whether or not the shipping information is normally read (step ST2), and if the shipping information is normal, the shipping information is stored in the shipping information storage unit 2b (step ST3). If the data reading is abnormal, an alarm is output to a speaker (not shown) (step ST4), the read data is cleared (step ST5), and the process returns to step ST1.

When the shipping information is normally read, the driver of the tank truck 1 then carries the portable wireless device 5 and performs the following work. That is, the identification code of the gas station identification code part 32 attached to the lid of the underground tank inlet storage box 31 of the gas station is read by the code reader 5b. Then, this identification code information is sent to the transceiver 3 via the handy terminal 5a and the antenna AT2, and further transmitted to the controller 2. When this identification code information is input to the controller 2, it is stored in the gas station identification code storage unit 2c under the control of the control unit 2a.

Next, the driver connects one end of the unloading hose 23 to the discharge port 22 at the tip of the common pipe section 18 and connects the other end of the hose 23 to the unloading destination underground tank inlets 33a to 33c. Connect to either (step ST
6). The underground tank oil type code attached to the lid of the underground tank inlet to which the hose 23 is connected is read by the code reader 5b (ST7). Here, the handy terminal 5a determines whether or not the code is normally read (step ST8), and if normal, transmits this oil type code information to the controller 2 via the transceiver 3 and It is stored in the tank oil type code storage unit 2d (step ST9).

If the reading is abnormal, an alarm is output to a speaker (not shown) (step ST10).
At the same time, a message indicating an abnormality is output to the display section 5f to notify the driver (step ST11). Then, the read data is cleared (step ST12), the process returns to step ST7, and the process of reading the oil type code based on the operation of the driver code reader 5b again is performed again.

Here, if the underground tank oil type code is normally read, and the above-mentioned gas station identification code and this underground tank oil type code are stored in each storage unit in the controller 2, the tank tanker vehicle is then read. The driver is the tank section 12
Of the hatch numbers 14a to 14e affixed to the manhole of the hatch portion for unloading and causing the code reader 5b to read it (step ST
14). Here, the handy terminal 5a determines whether or not the code is normally read (step ST1).
5) If normal, this hatch number code information is transmitted to the controller 2 via the transceiver 3 and stored in the hatch number code storage unit 2e (step ST1).
6).

If the reading is abnormal, an alarm is output to the speaker (step ST17), and a message indicating the reading abnormality is output to the display unit 5f to notify the driver (step ST18). Then, the read data is cleared (step ST19) and then step ST
14, the hatch number code is read based on the driver's operation of the code reader 5b again.

When the reading of the hatch number code is normal, the controller 2 stores this hatch number code in the hatch number storage section 2e as described above, and then stores it in the shipping information storage section 2b from the shipping information card 7. The code of this gas station read and the gas station identification code storage unit 2
After confirming the agreement with the gas station identification code stored in c, the hatch number code described above, the shipping information indicating the oil amount and the oil type previously stored in the shipping information storage unit 2b, and the underground tank oil are stored. Collation such as coincidence comparison with the oil type code stored in the seed code storage unit 2d is performed to determine whether the unloading is possible (steps ST20 and ST21).

When the controller 2 judges that the kind of oil to be unloaded and the amount of oil are inappropriate, the transceiver 3
The fact that unloading is impossible is transmitted to the portable wireless device 5 via the. Then, the mobile wireless device 5 outputs an alarm to the speaker (step ST22) and outputs a message indicating that unloading is impossible to the display unit 5f to notify the driver (step ST23). Then, the stored hatch number code is cleared (step ST19) and then step ST
Return to 14. As a result, the portable wireless device 5 performs the reading process of the hatch number code based on the re-operation of the driver's code reader 5b.

On the other hand, when it is determined that the type of oil to be unloaded and the amount of oil are appropriate, the control controller 2 transmits a message to that effect to the portable wireless device 5 carried by the driver via the transceiver 3. To display it on the display unit 5f. At the same time, an open signal is output to the three-way solenoid valve 20 provided in the vehicle body section 19 to open the shutoff valve 17 provided in the common piping section 18 (step ST25). In this case, the driver recognizes from the message displayed on the portable wireless device 5 that the operation is proper and opens the corresponding hatch bottom valve handle to open the hatch bottom valve corresponding to the read hatch number code. The opening operation is performed (step ST26). After that,
The discharge cock 21 is opened.

Then, the oil loaded in the corresponding hatch portion is injected into the underground tank through the common pipe portion 18 and the hose 23, and as a result, an appropriate amount of oil of a desired type is injected and stored in the underground tank. In this way, when the unloading of one type of oil is completed and the result becomes “Y” in step ST27, the driver presses the reset button 5c of the portable wireless device 5 (step ST28). Then, this operation information is sent to the control controller 2, and the control controller 2 uses the oil type code stored in the underground tank oil type code storage unit 2d,
The hatch number code stored in the hatch number code storage unit 2e is cleared (step ST29).

And if there is an unloading of the following types of oil,
Returning to step ST6, the driver changes the connection of the hose to the next underground tank. After that, the oil type code and the hatch number code of the corresponding underground tank are similarly read and stored, and the next oil is injected into another underground tank. When the operation of unloading all the oil is completed and the result becomes "Y" in step ST30, the driver presses the all reset button 5d of the portable wireless device 5 (step ST31). Then, this operation information is sent to the control controller 2, and the control controller 2 causes each of the storage units 2b.about.
All codes stored in 2e are cleared and the process ends (step ST32).

As described above, the control controller 2 uses the information input from the portable wireless device 5 based on the shipping information of the shipping information card 7 to store the oil type in the underground tank of the gas station and the oil type and oil in the hatch portion for unloading. The quantity and the quantity are automatically collated and judged. As a result, if the driver of the tank truck 1 or the person in charge at the unloading destination makes a confirmation error, an audible alarm and a message are output to the portable wireless device 5 of the driver to notify the error, so the unloading is performed. It can be done reliably. In addition, even if the driver accidentally opens the hatch bottom valve and the discharge valve 21, the shutoff valve 17 arranged in the common pipe section 18 is controlled to be closed. It is possible to prevent mixing of different types of oil into the underground tank at a certain place.
