This process system includes a group management host processing unit R10, a data relay processing unit R20, and a total process management machine processing unit R30.

First, when transmitting the molding results to the total process control machine, a key request operation is performed by the terminal. Next, actual data is set based on the requested key (ST11). Next, when the receivable signal from the data relay is transmitted to the group management host processing unit R10 within 1 minute, the actual data is transmitted to the data relay processing unit R20 (S
T13), on the other hand, if the receivable signal is not transmitted, output an error message and end (ST12A) (ST12).

Actual data is received from the group management host processing unit R10 (ST14). Next, this performance data is temporarily stored in an internal buffer in the data relay processing unit R20 (ST15). Next, it is checked whether or not the receiving line of the total process control machine R30 to which this result data is to be transmitted is ON (ST16), and if it is ON, this result data is transmitted to the total process control machine R30 (ST17). ). Note that the actual result data is transmitted to the total process control machine R30, and after the transmission is completed, the data relay processing unit R20
These performance data stored in are deleted.

In the total process control machine R30, if the receiving line is on, the actual result data is read (ST1
8). Next, these performance data are decoded into individual performance data (ST19). After that, various data processing and aggregation are performed, and the results and data are stored in a database (ST20).

[0006]

However, as described above, since the data communication is performed via the storage-type data relay device, the group management host transmits the result even when the total process management machine is stopped. can do. Even in this case, the group management host normally completes the communication process, so even if an error occurs during the communication between the data repeater and the total process management machine after that, the data check process is not performed and the total process management is not performed. There was a problem that even if a data record was missing on the machine, it would not be an error, but would be decrypted as it was, processed, aggregated the data, and stored them in the database, resulting in incorrect performance management.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a communication system capable of detecting omission of a data record when a total process control machine receives a result.

The production management system according to the embodiment of the present invention includes a group management host processing unit R1, a data relay processing unit R2, and a total process management machine processing unit R3.

When the production record data is transmitted to the total process control machine, it is input by key operation of the group control host (ST1). Next, a collation key code is added to the production record data. This collation key code is provided in the header portion of the actual result data, that is, in the comment area H1 of the actual result communication header, as shown in FIG. 3 (a), and 24 digits (24 bytes) are set. One digit of data is a byte unit, and JIS8 unit is used for transmission. As shown in FIG. 3 (b), in this layout, the text identification number D1 is assigned to the 1st and 2nd digits, and the transmission of the actual result data, during transmission,
The transmission identification code indicating whether the transmission is completed is set to "01",
Add as '00' and '10'. A number such as "001" is added to the third to fifth digits as the record number D2 in the file. Also, the data file number D is in the 6th to 8th digits.
A number such as'F 1'is added as 3. Furthermore, 2
The number of records in the file and the total number of records are added to the 1st to 24th digits. For example, if the number of original files of the actual data is 2 and the number of records of each is 20.22, '01001F 1 (12 spaces) 0020' is set as the verification key code in the first record that transmits the first file data. Is added. Also, '00001F 2 (12 spaces) 0022' is added to the first record for transmitting the second file data. Then, in the final transmission record, '10022F
2 (12 spaces) 0042 'is added. When the transmission identification code is "00", the 4-digit record number is set to "0000". In addition, each predetermined information is set based on the requested key (ST2)
..

Next, when the response confirmation signal indicating that the data relay to which the performance data should be transmitted can be received is confirmed within one minute, the performance data is transmitted to the data relay (ST4). On the other hand, if the response confirmation signal is not confirmed within 1 minute, an error message is output and the process ends (S
T3A) (ST3). Next, the result data transmitted from the group management host processing unit R1 is received by the data relay M3 (ST
5) The result data is stored in the internal buffer of the data relay M3 (ST6).

Next total process control machine line check
The steps of (ST7), transmission of actual data (ST8), and reception of actual data in the total process control machine processing unit R3 (ST9) are the same as (ST16), (ST17) and (ST18), respectively. Next, the total number of transmitted records of the collation key code of the received production record data and the total number of records actually received are collated (ST10). If it does not match the collation key code, the file number and record number of that data are output as error information from the collation key code of the record that was omitted along with the error message, and the process ends (ST13). If it matches the collation key code, the received data is decomposed for each data item and decryption work such as arranging is performed (ST11). Next, individual data is edited for each machine and each product number, so-called data processing such as aggregation of time information per day, storage, data aggregation,
Save to the database (ST12) and finish.
