2. Description of the Related Art Oil depots handle various petroleum products such as regular gasoline, high-octane gasoline, kerosene, light oil, and heavy oil. Shipment of these petroleum products from an oil depot is performed by a tank lorry having a plurality (for example, seven) of hatches (compartments). In addition, when shipping from an oil depot, the oil type and the amount of oil must be definitely assigned to each hatch of the tank truck. If the combination of the last shipment oil type and the current shipment oil type is incorrect,
This is because the risk of ignition (risk) increases. By the way, for the method and method of such allocation, for example,
No. 6395, Japanese Patent Publication No. 1-50679, and the like. Further, various modifications of the above-described methods and methods have been proposed and put into practical use. Less than,
A typical example will be described.

As a result, a waiting order occurs, and the waiting area for tanker trucks on the premises becomes crowded. Second, the driver of the loading dock first reads the hatch assignment table issued by the office, temporarily stores it, selects and mounts the loading arm and hatch based on the temporary storage, and then mounts the hatch. A troublesome operation such as connecting a sensor and a connector (mechanical connector) to obtain a confirmation signal must be performed. Therefore, an erroneous operation is likely to occur. When an erroneous operation occurs and a mounting confirmation signal cannot be obtained, the troublesome procedure of mounting and connecting must be restarted from the beginning. Third, since the sensor connector on the tank truck is connected with a copper wire (chain), there is a danger that the driver may trip over the copper wire and fall from the top of the tank. Fourth, if you notice a hatch assignment failure at the loading dock, you cannot change that assignment there. Therefore, it is necessary to return to the shipping management office again and perform the hatch assignment work again. Fifth, all tank trolley hatch occupancy management is performed by the shipping management computer (host computer) at the shipping management office, and the driver only uses the hatch assignment table for each shipment issued by the office.
