Problems solved by technology

[0004] 1) It is inconvenient to port to different platforms and compile because it is written in C language;
[0005] 2) Each business shares a folder to transfer files, which may cause data blockage of individual business;
[0006] 3) The old service does not support the e file (a special xml) format

Abstract

The invention discloses a data transmission method and system based on a reverse isolation technology, belongs to the field of power distribution system communication, and is used for realizing that transmitted data corresponds to associated services by establishing to-be-sent directories and receiving directories corresponding to the services and is transmitted to receiving areas of the corresponding services through isolation areas to finish data transmission. The invention has the beneficial effects that fair transmission of all service data is guaranteed, all the service data are compatible, and the novel reverse isolation requirement is met.

Description

technical field [0001] The invention relates to the field of power distribution system communication, in particular to a data transmission method and system based on reverse isolation technology. Background technique [0002] There is a concept of partition in the distribution automation system, which is divided into one zone and four zones. Servers in different zones cannot communicate directly and must rely on forward and reverse isolation. One zone transmits data to four zones through forward isolation, and four zones transmit data through reverse Isolation transmits data to the first area. Reverse isolation is a one-way file transfer device, which transfers the files in the designated directory of the server in the fourth area to the designated directory of the server in the first area. The reverse is not possible. The forward isolation is a one-way data transfer device. In the transmission device, the application program in the server in the first area establishes a con...
