Abstract

PURPOSE:To eliminate such an inconvenience that one must always carry a card to store data in it by a method wherein when oil loaded in a tank is to be unloaded at a destination, an earth connector of the tank truck is connected to a consignee's earth connector to transmit the stored data to a consignee's controller through the earth connectors. CONSTITUTION:When an earth connector 5 mounted on a loading stage 4 side is connected to an earth connector 3 of a tank truck 1 having a microcomputer housing 9, a process is carried out according to a programed flow chart. By connecting the earth connector 5, a vehicle number decoder 24A demands to a CPU 15 in the microcomputer housing 9 through a transmission driver and earth connector 5 to transmit the vehicle number at regular time intervals. On receipt of the demand signals of the vehicle number through reception driver 16, the CPU 15 transmits the vehicle number stored in a memory 15A to the vehicle number decoder 24A through the transmission driver 17 and the earth connector 5. Thereby, it becomes unnecessary to always carry a control data card.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a shipping system, and in particular to a shipping system configured to accurately and easily transmit and receive management data for oil to be loaded onto tanker trucks when loading and unloading the oil. Regarding the system.

Conventional Technology In the conventional shipping system, when a tank truck loaded with oil at an oil depot arrives at the delivery destination, the oil loaded in each hatch of the tank is transported to a designated underground location for each type of oil. It is unloaded into a tank.

At gas stations, it is necessary to prevent oil liquids of different oil types from being erroneously loaded and unloaded into underground tanks, such as dropping light oil into underground tanks for gasoline. Therefore, for example, when oil is loaded into a tank truck at an oil depot, management data such as the hatch number, oil type, and loading port can be sent to the 1iIJIIl device at the gas station through a telephone line, or the above management data can be stored on a magnetic card. It has been considered to store data and have a card reader at a gas station read the magnetic card to transmit the management data to a control device at the gas station.

Problems to be Solved by the Invention However, in the conventional shipping system, in order to prevent different oil fluids from being loaded and unloaded at the gas station, the delivery destination, the hatch number of the tank truck, the oil type, etc. Management data such as quantity (loaded amount) is required. However, when using a telephone line as described above, management data must be sent to the filling station through the telephone line each time a tanker truck leaves the oil depot, which complicates the shipping system and further increases the complexity of the shipping system. There is a problem in that the amount of information managed by the shipping monitor increases. In addition, when using a magnetic card, the driver must carry the card at all times, making it easy to lose or damage the card.Furthermore, when loading oil at an oil depot, management data regarding oil shipment is stored on the magnetic card. There is a problem that the data must be written in, and its handling is troublesome. In addition, magnetic cards have a limited lifespan, and if they are used for more than the number of times they can be used, there is a problem that the management data will not be stored even though it was written at the oil depot, and the card reader at the gas station will not be able to read the management data. There is also.

Therefore, an object of the present invention is to provide a shipping system that solves the above problems.

Means for Solving the Problems The present invention provides storage means for storing data on the oil loaded in the tank of the tank lorry near the ground connection of the tank lorry.
