When refueling is continued and the amount of oil in the chamber 3 of the oil storage tank 2 reaches level 3 (ST29 in FIG. 7), the alarm 23 says “I will prohibit refueling” and sends a refueling prohibition signal for that oil type. Output (ST30 in FIG. 7).

  Upon receipt of the refueling prohibition signal (ST2 YES in FIG. 5), the sales management control device 24 turns on the alarm 17 for the oil type to notify the refueling prohibition due to the shortage of oil (ST7 in FIG. 5). Thereby, the flow after step ST3 in FIG. 5 is not executed, and the oil supply device 6 cannot supply the oil type.

When the oil amount becomes level 1 (ST41 in FIG. 9), a shipping reservation signal is output from the transmission / reception means 25 to the headquarters 31 of the gas station via the communication network 30 (ST42 in FIG. 9).
Upon receiving the shipping reservation signal, the gas station headquarters 31 (ST51 in FIG. 10) outputs the shipping reservation signal to the oil tank station 32 (ST52 in FIG. 10).
The oil tank station 32 that has received the shipment reservation signal (ST61 in FIG. 11) sets the shipment reservation (ST62 in FIG. 11). As a result, the vehicle number of the tank truck 1 that has come to the oil tank station 32 is collated, and replenishment can be performed smoothly and efficiently.
The tank lorry 1 having the above-described configuration patrols a depopulated area or a stricken area to supply oil.

As shown in FIG. 12, when there is no commercial power source such as a stricken area, the power line 36 goes to the fueling position together with the power car 36, the power car 36 is stopped at a position away from the tank truck 1, and the power transmission line 37 connected to the power car 36. Is connected to the power connector 34 of the tank truck 1. Then, the fuel supply device 6 is driven by the electric power generated by the power supply vehicle 36 to supply the vehicle with fuel.
In particular, when fueling gasoline, using the battery (power source) of the tank truck 1 is prohibited by the Fire Service Law, so another power source vehicle 36 is stopped at a position away from the refueling position, and the power source from the power source vehicle 36 is turned on. It is supposed to take.
Thus, since the power supply vehicle 36 is stopped away from the tank truck 1, the safety of refueling can be ensured even if the engine of the power supply vehicle 36 is continuously driven during refueling.

As shown in FIG. 13, when the place to refuel is decided, the stop position of the power supply car 36 and the tank lorry 1 is partitioned by a white line or the like, the transmission line reel 38 is provided at each position, and both the transmission line reels 38 are sent. The wires 37 are connected. Then, the power supply car 36 is stopped at one stop position, the tank truck 1 is stopped at the other stop position, the power supply car 36 and the tank truck 1 are connected by a power transmission line 37, and fuel is supplied by the electric power generated by the power supply car 36. do.
If such a refueling position is provided in various places, the safety of refueling is further ensured, and there is no need to carry the transmission line 37.

As shown in FIG. 14, if the tank lorry 1 has a stop 39 lower than the high place H at the refueling position and an oil breakwater 40 is provided, even if oil leaks during refueling, it does not flow out to the surroundings. It is safe.
In places where commercial power can be secured, such as in depopulated areas, the tanker 1 only needs to go to the refueling position and receive power from the commercial power supply for refueling.

  Since the oil supply system is based on a tank truck equipped with all the oil supply facilities, it is possible to efficiently supply oil even in depopulated areas or disaster areas where there are few customers.
