[0002]

2. Description of the Related Art At an oil depot for loading oil such as gasoline, light oil, or kerosene on a lorry vehicle for shipment, when an order is received from a customer such as a gas station, the customer's name and order are sent to the host computer in the management office. Input order data such as oil type (loading oil type), quantity (loading amount), delivery date, etc., and create a delivery plan for each lorry vehicle based on this order data. If the wrong combination of the previously shipped oil type and the currently shipped oil type is mistaken, there is a risk of explosion and ignition. When the lorry arrives at the oil depot, the driver causes the card reader of the management office to read the car number card for identifying the lorry. This card reader is connected to the above-mentioned host computer. By reading the vehicle number card, the host computer outputs a delivery plan prepared in advance for the lorry vehicle corresponding to the vehicle number card to the hatch allocator connected in the same manner as the card reader. As a result, the delivery plan of the truck is displayed on the display of the hatch allocator.

<First Prior Art> The driver operates the operation unit of the hatch allocator at the management office with reference to this delivery plan, and the hatch assignment data relating to the current delivery of the lorry vehicle (the current delivery Type and quantity of oil to be loaded in lorry vehicle)
And the delivery destination etc. are set and input. These operations are called hatch allocation. And when this hatch allocation is completed,
The contents are transmitted from the hatch allocator to the host computer. The host computer stores the hatch allocation data set by the hatch allocator, the delivery destination, etc. in the storage section in correspondence with the vehicle number card, that is, the lorry vehicle identification data, in preparation for the actual loading work. Further, the printer issues a delivery table in which the hatch loading data and its delivery destination are described to the driver.

<Second Prior Art> As an improvement, in Japanese Patent No. 3236036 (Japanese Patent Laid-Open No. 5-85596), this hatch allocation work is performed at a lorry loading station, and a printer provided with the hatch allocation data in the lorry vehicle. It is printed out.

[0005]

However, the shipping system as described above has the following problems. <First conventional technology> Since the hatch allocation work is performed at the management office of the oil depot, the lorry will be congested near the entrance. Further, if the host computer does not receive the necessary data for the lorry due to some trouble, the driver will input the necessary data, and the work will take longer.

<Second Prior Art> At the Raleigh loading station, the equipment used is basically explosion-proof. Therefore, the shipping slip printer is installed inside the truck. Also, since the card used is only for checking the car number, the control control computer (island control computer) installed at the lorry loading site must be connected to the host computer of the management office during communication. The load on the host computer increases.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention allows a driver to carry an IC card.
The C card stores the required data such as vehicle number, oil type, quantity, and history for identifying the truck, inputs and outputs those data to the island control computer at the loading dock, and performs the hatch assignment work on the explosion-proof shipping monitor. , Print out the shipping slip at the management office.

[0008]

According to the present invention, when the tank truck arrives at the oil tank, the driver almost goes straight to the shipping site and inserts the IC card into the card reader at the shipping site to check the vehicle number, oil type,
By reading the data such as the quantity and history, the hatch allocation work can be performed at the shipping site, so that the congestion at the entry point of the oil tank is eliminated. further,
Since the trouble load on the host computer does not increase, the number of loading control devices managed by the host computer can be increased.
