Method for implementing network five defending locking system of transforming plant without person on duty

The invention relates to a method for realizing an unattended substation networking five-defense block system, which specifically comprises the following steps: 1. establishing a system network; 2. and establishing a system interface: (1) establishing a graphic display and processing COM module; (2) adopting FTP documents to upload or download to keep the graphic data synchronization mainly by the method of transferring local graphic data; (3) and establishing standard communication stipulations between the five-defense block system and the computer key. The invention has the beneficial effects that a networking five-defense block management platform is established to realize five-defense block function; the unity of once wiring diagram graphic data and the information sharing between an electric transmission and transformation geographical information system and the five-defense block system substation are realized; and the download and pass back of the computer key data between the five-defense block system and a plurality of manufacturers is realized based on the standard communication stipulations between the five-defense block system and the computer key.
