Description

[Technical Field]

[0001] The present invention relates to a filling system using a two-dimensional barcode. [Background technology]

[0002] Gas filling systems are installed at filling stations where propane gas (LPG) is filled into gas cylinders. This gas filling system consists of a gas filling machine, an explosion-proof gas filling handheld terminal carried by the worker, and a computer system (server, PC, etc.) located in the office. This explosion-proof gas filling handheld terminal is connected to the office computer system by wire.

[0003] Generally, when filling gas cylinders with propane gas and selling them to customers, a one-dimensional barcode label is printed using a printer on an office computer system, and this one-dimensional barcode label is affixed to the gas cylinder. A worker then transports the gas cylinder to the customer in a vehicle.

[0004] The type of one-dimensional barcode label mentioned above differs depending on the filling station. Figures 10(a) and 10(b) show one-dimensional barcode labels at a medium-sized filling station. In the case of the one-dimensional barcode in Figure 10(b) (core filling station compatible barcode (CPDE39)), it is about 23 digits long and contains the minimum information required for filling.

[0005] From the left, the markings (ABC12345), container capacity (50.0), tare weight (36.5), fill-by date (fill-by date), and company name (1234) are shown.

[0006] Figure 11(a)(b) shows a one-dimensional barcode label at a small-scale filling station. The one-dimensional barcode label in Fig. 11(b) is for NW7, which generally has 6 to 8 digits. The one-dimensional barcode in Fig. 11(b) is for CODE39, which generally has 8 to 10 digits. This one-dimensional barcode is then affixed to the gas cylinder, and the gas cylinder is filled with the amount corresponding to the container's capacity using a filling machine.Then, the office's computer system associates the one-dimensional barcode data with the fill amount, fill deadline, container expiration date, etc. (hereinafter referred to as container information) and manages them.In other words, one-dimensional barcode labels created for each filling station are affixed to gas cylinders for management. When a gas cylinder is brought into a filling station, the one-dimensional barcode on the one-dimensional barcode label attached to the gas cylinder is read using a one-dimensional explosion-proof handheld terminal, and the time of filling, the filling expiration date, etc. are manually confirmed, and the amount to be filled is calculated based on the weight measured by the filling machine, and the cylinder is filled. The amount to be filled, the filling date, etc. are added to the container information and managed by computer. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 3579019 Summary of the Invention [Problem to be solved by the invention]

[0008] However, there is a lot more information to manage at filling stations, and 23 digits is not enough. Meanwhile, gas cylinders filled at other filling stations may run out and be brought in by customers. However, because these gas cylinders were filled at other filling stations, the necessary information must be newly entered into a computer each time, and then the filling process and management data must be generated. When a large number of cylinders are brought in due to a disaster or other reason, the work at the filling station increases, resulting in higher costs for the filling process.

[0009] The present invention has been made to solve the above problems, and aims to provide a filling system that uses two-dimensional barcodes that can immediately fill gas cylinders filled at other filling stations without any administrative work. [Means for solving the problem]

The information is stored in the filling completion registration information memory 124f and also stored in the two-dimensional barcode container information memory 12 5 and memorize it in association with (d53).

[0079] Therefore, the appropriate amount of filling can be obtained automatically and filled without the need for a clerk to perform any additional input work.

[0080] On the other hand, in d39 shown in Figure 5, if the two-dimensional barcode container information presence / absence determination unit 122 determines that registered two-dimensional barcode container information Rbi having the container engraving number CBi contained in the cylinder barcode information bBi from the explosion-proof handheld terminal does not exist in the two-dimensional barcode container information memory 125, it performs two-dimensional barcode container information registration processing as shown in Figure 6 (d55).

[0081] Therefore, even if the cylinder is managed at another filling station, the filling amount can be automatically obtained without performing any new input work.

[0082] (Two-dimensional barcode container information registration processing) In the two-dimensional barcode container information registration process, the cylinder barcode information bBi, which is a bit string of "1" and "0", is divided into a predetermined number of digits from the start bit based on the barcode item identification table Ki.

[0083] For example, as shown in Figure 9, the 10 digits from the start bit are the label number, the next 3 digits are the symbol for the container marking number, the next 5 digits are the number for the container marking number, the next 6 digits are the owner code, etc.

[0084] 9 indicates the number of digits and "V" indicates the decimal point. These combinations are then stored in the two-dimensional barcode container information memory 125 as new registered two-dimensional barcode container information Rbi.

[0085] Then, the filling amount calculation unit 126 is started, and the above sequence of d19 to d53 is performed to calculate the filling amount (d57), and this filling amount is associated with the cylinder barcode information bBi and stored in the filling amount calculation memory 124d as per-container filling amount calculation information Gi (cylinder barcode reading information bBi, filling machine number) (d59).

[0086] On the other hand, if the barcode type determination unit 128 determines in d37 that the cylinder barcode information bBi is a one-dimensional barcode, it activates the two-dimensional barcode label issuance instruction unit 129 and outputs this one-dimensional barcode information (d61).

[0087] The two-dimensional barcode label issuing instruction unit 129 decodes the cylinder barcode information bBi and Engraving The number is displayed on a computer screen in a predetermined format (e.g., Excel). d 63).

[0088] If only a one-dimensional barcode is attached to the container, worker Ai will issue Then, write down the type of container, type of gas, etc. and hand it over to the office clerk.

[0089] The office staff will answer the number written on the note. issue In addition to the type of container and gas type, the name of the worker, filling station code, name of the new user, address information, etc. are written, and these sets are used as a new Registered The clerk generates two-dimensional barcode container information and stores it in a memory (not shown).

[0090] The two-dimensional barcode label issuing instruction unit 129 Registered two-dimensional barcode The container information is converted into two-dimensional barcode data (bit string, error correction, mask, etc.), and output to the two-dimensional barcode label printer 140 to print and issue a two-dimensional barcode label 3 (d67). The worker then attaches this two-dimensional barcode label to a newly brought-in container (d69). [Explanation of symbols]
