FIG. 2 shows an example of the code contents of the IC card 19 possessed by the lorry driver. The contents are car number, top loading or bottom loading type, hatch H1-H4 number, discharge pipe number,
The oil type and the oil amount are stored at the time of loading at the oil depot, and the unloaded code is stored in the space a at the time of unloading.

Next, a mode of control will be described with reference to FIGS. In FIG. 3, the top loading type tank truck R1 arrives at the gas station A, and reads the IC card 19 into the card reader / writer 18 (step S).
1) When the driver connects the ground wire 13a to the lorry R (step S2), the control device 10 determines whether or not the lorry R is a top-loading type lorry (hereinafter referred to as a top car) R1 based on the stored contents of the IC card 19. (Step S
3). In the case of NO, that is, in the case of the bottom loading type lorry (hereinafter, referred to as a bottom vehicle) R2, the flow proceeds to the flow shown in FIG. 4, and in the case of YES, that is, in the case of the top vehicle R1, the driver connects both ends of the lubrication hose 30 to the discharge pipe 24,
a and the lubrication valve 2a, and the first sensor 23 is connected to the first identification piece 26a (step S4).
Reads the oil type and the space amount of the tank T1 based on the signal from the liquid level measuring unit 4a corresponding to the tank T1 of the connected lubrication pipe 1a, and reads the discharge pipe 24a based on the signal from the first sensor 23. Is read (step S5). In this way, the control device 10 can determine which tank is connected. Next, the driver connects the second sensor 27 to the second identification piece 22a (Step S6),
When the bottom valve 21a is opened by turning the bottom valve handle 20a, the control device 10 determines the oil type and amount of the hatch H1 to be unloaded from the data of the discharge pipe 24a, the second sensor 27 and the data of the IC card 19. It is determined whether or not it is OK compared with the tank T1 (step S7).
Is opened (step S8). Therefore, the driver operates the discharge pipe valve 2
When 5a is opened, unloading can be performed. When the first sensor 23 is removed after the unloading is completed (step S9), the control device 10 determines that the unloading is completed, and the card reader
The writer 18 stores the unloaded code in the corresponding part a of the IC card 19 (step S10). If all unloading is completed and the driver removes the other sensor, that is, the second sensor 27, and removes the ground wire 13a (steps S11 and S1).
2, S23, S24), the control device 10
(Step S25), and the control ends.

When the oil in the hatch H2 is to be unloaded continuously, in step S9, the first sensor 23 is not removed (in the case of NO), and if the second sensor 27 is removed (step S13), the step The unloaded code is stored as in S10 (step S14). Then, when the second sensor 27 is connected to the second identification piece 22b (step S1).
5) Return to step S7 and perform the above operation. If the first sensor 23 is disconnected without connecting the second sensor 27 (Step S16), the above-described Step S23 and subsequent steps are executed.

When unloading from one discharge pipe 25b is completed after unloading one discharge pipe 25a, the first sensor 23 is attached to another hatch.
1 or step S23 is YES. Therefore, in this case, the process returns to step S5, and the same operation as described above is performed.

If step S7 is NO, that is, if the oil type / oil amount is not OK for the tank T1, the control device 10 activates the alarm 16 to issue a warning (step S1).
7). In this case, the driver connects the lubrication hose 30 to the discharge pipe 2
4a to remove the first sensor 23 and another discharge pipe 24b.
Or the second sensor 27 is detached and connected to the second identification pieces 22b, 22c,... Of other hatches (step S18). Then, the process proceeds to step S23, where the second sensor 27 is removed (step S19), and when the second sensor 27 is connected to the second identification piece of another hatch (step S20), the process returns to step S7. When the first sensor 23 is disconnected without connecting the second sensor 27 (step S21), the process proceeds to step S23.

FIG. 4 shows a control mode for the bottom wheel R2. In step S3 of FIG. 3, the driver is determined to be the bottom vehicle, and the driver connects the lubrication hose 30 to the discharge pipe 2 for example.
8a and the lubrication valve 2a, and the first sensor 23
9a (step S26), the oil type / oil amount and space amount of the tank T1 are read based on the signal from the liquid level measuring unit 4a of the tank T1 of the connected lubrication pipe 1a.
The number of the discharge pipe 28a is read based on the signal from the first sensor 23 (Step S27). Next, the oil type and oil amount of the hatch H1 to be unloaded are determined from the data of the IC card 19, and it is determined whether or not the hatch H1 is OK compared with the tank T1 (step S28). Open (step S29), and unloading is enabled. Therefore, when the driver opens the valve (not shown) to perform unloading and unloads and removes the first sensor 23 (step S30), the card reader / writer 18 unloads the corresponding part a of the IC card 19. The stored code is stored (step S31). When all unloading is completed and the driver removes the first sensor 23 and disconnects the ground wire 13a (steps S35 and S36), a slip is issued from the printer 17 (step S37), and the control is terminated.

When unloading the oil of another hatch, the first sensor 23 is connected to the identification piece 29b of the other discharge pipe 28b (step S35) before the ground wire 13a is removed (step S36). Move to step S27. Also,
If step S28 is NO, that is, if the oil type / oil amount is not OK for the tank T1, the control device 10 activates the alarm 16 to warn (step S32). Then, when the driver removes the first sensor 23 and connects it to another first identification piece 29b of, for example, the discharge pipe 28b (step S3).
3) Go to step S35.
