- A and the central processing unit via the intermediate control unit TCU
It is connected to the CPU and transmits the status of the terminal TM and occasional information, such as information regarding the issued ticket type and amount, to the central processing unit CPU. In the terminal TM,
Information about the types of tickets to be sold, the number of tickets sold, and the total amount of tickets sold is stored in both the terminal TM and the central processing unit CPU, and preparations are made to report the number of ticket types to the central processing unit CPU when dealing with new customers. . In the terminal TM, when polling is received from the central processing unit CPU, the central processing unit CPU
Report to. Such central processing unit
The CPU has a storage device, and updates the contents of its own storage device after checking each of the above-mentioned items and instructing the terminal to issue a ticket. Now, if a failure occurs in the transmission line between the line controller TCP-B and the terminal TM, the central controller CPU will
Indication information such as "Tickets can be issued" for the terminal TM is
This means that data cannot be transmitted during information processing. At this time, the central processing unit CPU processes the ticket as sold, since the "ticket issuance permitted" instruction has been completed, and on the other hand,
Since the terminal TM has not yet issued the command, the line control device TCP-A on the central processing unit CPU side of the transmission line prints the command information to the central processing unit CPU on an attached printer, and can give a warning to the operator.
Then, the operator manually operates the central processing unit.
Notify the CPU of information correction. however,
As mentioned above, if a line failure occurs, it will be a hassle and manual operation will require the above-mentioned ticket type, number, etc.
It is easy to make mistakes regarding monetary figures.

内容を補正（例えば減算）すること。(5) Embodiment of the invention Figure 2 shows the first embodiment of the invention in Figure 1.
A schematic configuration diagram of a line control device TCP-A is shown. Note that the second line control device TCP-B also has a substantially similar configuration. Further, FIG. 3 shows an operation time chart of FIG. 2. In Figure 2, T/
R is a signal transmitter, ADB is a buffer for attention data, RDB is a buffer for return information,
The line control device has two signal transmitting/receiving units T/R and one each of attention data buffers ADB and RDB.
They are assembled into one set and are provided in correspondence with the terminals. Furthermore, the MPU is a microprocessor that controls input/output operations to each of the above-mentioned parts. Prior to the start of operations performed by the intermediate processing device such as ticket issuing processing, the first line control device TCP-A polls the status of each terminal TM via the second line control device TCP-B. If the terminal TM is now operational, the attention data AD is stored in each attention data buffer ADB of the corresponding terminal TM in preparation for operation when polled by the central processing unit CPU. Then, the first line control device TCP-A is polled from the central processing unit CPU or the intermediate control device TCU controlled by it, and if it is a request signal ENQ1 to the first terminal, attention data AD1 of the corresponding first terminal is polled. send out. The intermediate processing unit TCU sends return information RD 1 to the first terminal, and the first line control unit
TCP-A stores it in the return information buffer RDB, and when it is successfully stored, issues a transmission request to the transmission line to the second line control device TCP-B. Next, the return information RD 1 is extracted from the buffer RDB and sent to the terminal, and when the process is completed normally, the buffers ADB and RDB for the first terminal are cleared.
The intermediate processing unit TCU sends a request signal to the second terminal.
When ENQ 2 is sent, the first line controller TCP
-A sends back AD 2 . This operation continues, but if during the transmission procedure to the second line controller TCP-B, the microprocessor MPU detects that the procedure is no longer progressing due to a fault LF occurring on the transmission line, etc. Then, the microprocessor MPU checks whether or not information is stored in the return information buffer RDB, and clears the stored information. The next order of the terminal in the buffer is determined by the attention data buffer corresponding to the terminal.
Add subtraction processing information ADD to the buffer storage contents in ADB. The information ADD for subtraction processing is the following information prepared in advance with a corresponding terminal number added. In other words, if the line to the first terminal is at fault, (a) the return information RD 1 could not be sent normally to the second line control information, and (b) the previously sent return information RD 1 was canceled and the information was sent before that information was sent. Correcting (for example, subtracting) the stored contents of the central processing unit to the state of .

報告されるのでそれも検知できる。It is. The next poll from the intermediate control unit TCU,
For example, when a request signal ENQ 2 for terminal 2 arrives, the first line control device TCP-A outputs the original attention data AD 2 as attention data AD 2.
In addition to this, the above-mentioned subtraction processing information ADD is sent. The intermediate control unit TCU learns from this attention data AD 2 that the state at the first terminal is different from the expected state on the intermediate processing unit TCU side, and performs processing such as subtracting the ticket sales amount and number of tickets, and then transmits the information to the second terminal. , information including predetermined return information RD 2 and information indicating that the subtraction process has been performed is sent. TCP-A receives the information (sends predetermined information RD 2 to the second line controller TC-B, and then clears AD 2. If there is a failure on the way to the second terminal, the third terminal It can also be detected because it is reported by attention data.
