SUMMARY OF THE INVENTION Therefore, an object of the present invention is to accurately input the oil type and the amount of oil to the on-vehicle control device even if the data of the control device at the oil tank cannot be input to the on-vehicle control device. It is to provide a tank truck that can.

[0005]

According to the present invention, each hatch is provided with a detector and a level gauge for detecting an oil type identification piece attached to a loading arm of an oil tank. In a tank truck having a controller for receiving a signal from the liquid level and outputting an operation signal to the alarm, the controller outputs an operation signal to the alarm when there is no signal from the detector when the signal is input from the liquid level gauge. It has a load determination means for outputting and a load data storage means for storing, for each hatch, the oil type from the detector and the oil amount from the level gauge based on the signals from both the level gauge and the detector.

[0006]

[Explanation of Action and Effect] At the oil tank, the type of oil supplied from the loading arm is determined. Therefore,
An oil type identification piece is provided on the loading arm in advance and connected to the detector of the tank truck when refueling. Then, the oil is supplied from the loading arm.If the oil type is different, the liquid level gauge detects the rise in the liquid level, but the detector that detects the oil type does not output a signal.In this case, the alarm is activated. Notify you of an incorrect fueling. When the oil type is correct, both the liquid level gauge and the detector output signals, so that the oil type and the oil amount are stored in the cargo data storage means for each hatch.

As described above, according to the present invention, only by providing the loading arm of the oil tank with the oil type identification piece for identifying the oil type, the processing can be performed by the control device on the tank truck side, and the invention can be applied to all oil tanks. Therefore, the work in the oil tank can be performed rationally.

The oil type and the oil amount data stored in the tank lorry controller according to the present invention are, for example, as described in Japanese Patent Application Laid-Open No. 2-72093, mixed oil at the time of unloading at a gas station. Can be used for prevention. Therefore, according to the present invention, it can be suitably used both when loading and unloading a tank truck.

Therefore, it is preferable that the storage of the cargo data storage means can be output to the outside through the connector.
