Description

The present invention relates to a filling system using a two-dimensional bar code.

A gas filling system is installed at the filling station where the gas cylinder is filled with propane gas (LPG).
This gas filling system consists of a gas filling machine, an explosion-proof gas filling handy terminal carried by a worker, and a personal computer system (server and personal computer, etc.) arranged in the office. This explosion-proof gas-filled handy terminal is connected to the office computer system by wire.

Generally, when a gas cylinder is filled with propane gas and sold to a customer, a one-dimensional barcode label is issued using a printer of an office computer system, and the one-dimensional barcode label is attached to the gas cylinder. Then, a worker carries this gas cylinder to a customer by vehicle.

The types of one-dimensional barcode labels mentioned above differ depending on the filling station. Figures 10 (a) and 10 (b) show one-dimensional barcode labels for medium-sized filling stations.
In the case of the one-dimensional bar code (bar code corresponding to the core filling station (CPDE39)) in FIG. 10 (b), the content contains the minimum information necessary for filling in about 23 digits.

From the left side, the stamp (ABC12345), container capacity (50.0), tare weight (36.5), filling deadline (filling deadline), and business office (1234) are shown.

11 (a) and 11 (b) show one-dimensional bar code labels for small filling stations.
The one-dimensional barcode label shown in FIG. 11B is for NW7, and generally has 6 to 8 digits. Further, the one-dimensional barcode in FIG. 11B is the case of CODE39, and is generally 8 to 10 digits.
Then, such a one-dimensional barcode is attached to a gas cylinder and filled with a filling machine in an amount corresponding to the container capacity. Then, the personal computer system in the office manages the one-dimensional barcode data in relation to the filling amount, filling deadline, container deadline, etc. (hereinafter referred to as container information). In other words, a one-dimensional bar code label generated for each filling station is attached to the gas cylinder for management.
Then, when the gas cylinder is brought into the filling station, the one-dimensional barcode of the one-dimensional barcode label attached to the gas cylinder is read by using a one-dimensional explosion-proof handy terminal, and the filling is done manually at any time. After confirming the filling deadline, etc., the filling amount is obtained from the weight measured by the filling machine and filled, and the filling amount, filling date, etc. at this time are added to the container information and managed by a computer.

Japanese Patent No. 3579019

However, the information managed at the filling station has a large amount of information, and about 23 digits is not sufficient.
On the other hand, the remaining amount of gas cylinders filled in other filling stations other than your own filling station may run out, and you may be brought in by diving.
However, since it is a gas cylinder filled by another filling station, it is necessary to generate filling work and management data after newly inputting predetermined information required at the filling station on a personal computer each time. If a large amount is brought in due to a disaster or the like, the work at the filling station will increase, and as a result, the filling work will be costly.

When it is determined that the two-dimensional bar code container information memory 125 does not exist, the two-dimensional bar code container information registration process is performed as shown in FIG. 6 (d55).

Therefore, even if the cylinder is managed at another filling station, the filling amount can be automatically obtained without performing a new input operation.

(Two-dimensional bar code container information registration process)
In the two-dimensional bar code container information registration process, the cylinder bar code information bBi, which is a bit string of "1" and "0", is divided into predetermined digits from the start bit based on the bar code item identification table Ki.

For example, as shown in FIG. 9, for example, 10 digits from the start bit are the label number, the next 3 digits are the container stamp number symbol, the next 5 digits are the container stamp number number, and the next 6 digits are the owner code. ... and so on.

Note that () in FIG. 9 indicates the number of digits, and “V” indicates a decimal point.
