Next, when the processing start instruction is received from the handy terminal 5 (step S79), the instruction is any one of "filling", "registration", "form", and "emergency" depending on the content of the processing start instruction. Judge whether it is processing (step S
80).

When the processing start instruction is "filling", it is checked whether or not the container number indicated by the bar code from the handy terminal 5 exists in the container master 81 (step S81), and it does not exist. In this case, the error flag is set in the error text (step S8).
2) The error flag is transmitted to the handy terminal 5 (step S85).

On the other hand, when the container number indicated by the bar code is present in the container master 81, the filling control system (corresponding to the filling machine control processing unit 92) is activated (step S8).
3) Control the filling machine 3. Therefore, the container 2 can be filled with gas. After that, the next processing permission flag is set (step S84), and the next processing permission flag is transmitted to the handy terminal 5 (step S85).

If the process start instruction is "registration", container master registration is performed (step S86), and step S8 is performed.
Go to 3. Therefore, it is possible to register or change the information of the container master on the center side on the site side.

If the processing start instruction is "form", the form output program is started (step S87), the form is printed (step S88), the print end flag is set (step S89), and the form is printed. The print information is transmitted to the handy terminal 5 (step S90). Therefore, the display area 55 of the handy terminal 5 displays the selection form of the printing range. That is, by instructing the center to print the form on the work site side, the worker can obtain detailed information such as a delivery statement, a filling diary, a shipping statement, and an inspection statement from the center 7a. Therefore, workability can be improved.

When the process start instruction is "urgent", container master registration is performed (step S91), the filling control system is operated (step S92), and the process proceeds to step S84. Therefore, it is possible to register or change the information of the container master on the center side on the site side.
