In receiving the transfer request from the center, a CPU61 of the device 5 stores the information edited in the order of ID codes to the area 62 with the operating processing from the information of the areas 63-65 and the stored information is transmitted from the device 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a communication control system that transfers information from a terminal device to a center device, and particularly relates to a communication control system that transfers information from a terminal device to a center device. This invention relates to an information transfer control method when transferring information.

Conventionally, communication line status information (hereinafter simply referred to as "line information") is stored in a storage section of a terminal device, and this information is transferred to the center device at regular intervals, for example, based on a transfer request from the center device. However, at the time of this transfer request, there was a message that there was information that needed to be urgently sent to the center device, and in this case, the terminal device would unconditionally transfer the line information, resulting in a delay in the transfer of highly important information. There was an inconvenience.

In order to solve the above-mentioned inconvenience, the present invention, in response to a request to transfer line information, retrieves line information and other various information from a storage unit in order according to the information priority order, edits it, and transfers it to a center device. The purpose of this invention is to provide a new information transfer control method that can quickly transfer urgent and important information.

The present invention will be specifically described below based on embodiments shown in the drawings.

FIG. 1 shows a communication control system that transfers various information from a terminal device 2 to a center device 1. As shown in FIG.

The center device 1 and the terminal device 2 each consist of communication control devices 3, 5 and information processing devices 4, 6, each of which includes an arithmetic control section (indicated by CPU in the figure) and a storage section (indicated by RAM in the figure). ). The communication control devices 3 and 5 are for transmitting and receiving information, and the information processing devices 4 and 5 are for transmitting and receiving information.
6 processes various information related to transmission and reception.

Details of the communication control device 5 and information processing device 6 in the terminal device are shown in FIG.

′! The communication control device 5 in the illustrated example is RAM-Al in the figure.

A storage section 50 having storage areas 52 and 53 indicated by A2
and an arithmetic control unit 51 that controls operations such as reading received information and reading transmitted information from the storage unit 50. A storage area 52 of the storage unit 50 is used as a buffer for temporarily storing received information and transmitted information.
3 stores and holds line information having the configuration shown in FIG. 3(1).

This line information includes data (
1), CRC (Cyclic Redundancy)
Data (2) indicating the number of errors checked using the Check) method, and data (3) indicating the number of invalid frames received.
), data (4) indicating the number of times the receive buffer has exceeded;
Contains data (5) indicating the number of times the transmission time has exceeded,
These data groups contain ID codes (Identifi-c).
ation Code) and information indicating the data length are added. The ID code consists of 8 bits1,
2. . . , n, and this number code is assigned to each piece of information based on the importance of the information content.

Next, the information processing device 6 stores RAM -Bl, B2゜B in the figure.
3. A storage unit 6 having storage areas 62 to 65 indicated by B.
0, and an arithmetic control section 61 that controls operations such as reading reception information and line information into the storage section 60, and editing and reading transmission information. Storage area 63 of storage unit 60
stores the received information and line information from the center device 1,
The storage area 64 stores various types of transmission information to be transferred other than line information. The structure of this transmission information is shown in FIG. 3(2), in which 10 codes, information indicating the data length, and a stopper indicating the end of the transmission data are added to data indicating the specific content.

In addition, the storage area 65 stores ID codes as numbers 1, 2...
, n, and the table stock/f is stored at the end. Furthermore, the storage area 62 is the storage area 63, 64.
This section extracts and edits each piece of information in the order of ID code numbers.

FIG. 4 shows the operational flow of the information transfer control system according to the present invention.

In the drawing, step 71 determines the presence or absence of received information, and if the determination is YES, the received information is temporarily stored in the storage area 52 of the storage unit 50, and then, in step 72, the received information is stored in the storage area 52.
2 to the storage area 63 of the storage unit 6. Also N
If the determination is O, input/output operations are restricted and the process waits for information on transmission and reception (step 73). In the next step 74, it is determined whether or not the received information includes data requesting transfer of line information.If the judgment is YES, the line information accumulated in the storage area 53 of the storage unit 50 is storage area 6
Transferred to 3. Further, if the determination is NO, other reception processing (for example, information processing other than line information) is executed (step 7
6). Next, in step 77, the counter 1 in the arithmetic control unit 61 is set, and in step 78, the information of ID code 1 in the storage area 65 is stored in the storage area 63.
．． 64 is stored, and YES.
Upon this determination, the information related to ID code 1 is transferred to the storage unit 62 (step 79). On the other hand, the determination in step 78 is N.
In the case of O and when the transfer process in step 79 is executed, the contents of the counter i are incremented by 1 in step 80, and then the checks and processes in steps 78-79 are executed for the information of ID code 2. In this way, the same process is executed until the contents of the storage area 65 specified by the counter i reach the table stopper, and the contents of the storage area 62 are
Various information including line information is edited as a series of transmission information in numerical order of the D code. When the determination in step 81 is YES, the edited transmission information in the storage area 62 is temporarily moved to the storage area 52 of the storage unit 50, and then
It is transmitted to the center device 1 (steps 82 and 83).

As described above, the present invention employs a method in which line information and other transmission information are edited in accordance with priorities in response to a line information transfer request and transferred to the center device. If there is highly important information to be transmitted, it can be transferred as quickly as possible, and in addition, line information and other transmission information can be transferred in a series of transmission processes, improving transmission efficiency. be effective.
