Referring to fig. 3, a schematic diagram of a first preferred embodiment of the present invention is shown,

copying a file to be transmitted to an isolation area by the first transceiving area;

backing up the file to be sent to a backup area

The isolation area sends the received file to be sent to a second transceiving area through a communication protocol;

after receiving the file to be sent, the second transceiving area sends a receiving receipt to the isolation area;

the isolation area receives the receipt returned by the second transceiver area by the open communication interface within the appointed time, and after receiving the corresponding receipt within the appointed time, the first transceiver area confirms that the file transmission is finished after receiving the receipt sent by the isolation area, and sends a command of deleting the backup file to the backup area; and after receiving the command of deleting the backup file, the backup area deletes the backed-up file to be sent and ends the operation.

And when the receiving receipt is not received within the specified time, closing the communication interface and sending the timeout information to the first transceiver zone.

After the overtime information is sent to the first transceiving area, the overtime times are accumulated;

and judging whether the overtime times are larger than a threshold value, if so, returning to execute the first step, otherwise, deleting the file to be sent in the backup area, prompting that the file is abnormally transmitted, and ending the operation, wherein the threshold value can be defined by users.

The concept of having partitions in a distribution automation system is divided into one and four zones. Servers of different partitions cannot communicate directly and must rely on forward and reverse isolation. One region transmits data to four regions through forward isolation, and four regions transmits data to one region through reverse isolation.

Reverse segregation is a unidirectional file transfer mechanism. And transmitting the files in the specified directory of the four-zone server to the specified directory of the one-zone server, and otherwise, not executing the files.

Forward isolation is a unidirectional data transfer device. And the application program in the first area server establishes a TCP connection with the four area server through forward isolation and transmits data.

In the distribution automation system, data transmitted between four areas is critical and is not lost.

The method is characterized in that file receiving confirmation is added between a four-zone file sender and a one-zone file receiver, a waiting and overtime retransmission mechanism is added for the four-zone file sender, and the basic steps are as follows:

1) and the four-area file sender copies the file to be sent to the reverse isolation sending directory, backups the file at the same time, and waits for the file receiving confirmation of one area.

2) When the file receiver in one area processes the file transmitted in the reverse isolation, the file receiving confirmation (including the file name) is transmitted to the four areas through the forward isolation.

3) And the four-zone file sender receives the file transmission confirmation, relieves the waiting, deletes the file backup and normally ends the file transmission.

4) And the four-zone file sender waits for overtime of file receiving confirmation, returns to the step 1 if the file receiving confirmation is overtime for the first time), deletes the file backup if the file receiving confirmation is not overtime for the first time, and abnormally ends the file transmission.
