With the development of electric power industry

the importance of using electric power communication to ensure the security of electric power dispatching is becoming greater and greater

but it is impossible to achieve 5×7×24 hours of inspection and 100% fault detection rate at the first time because of "disperse maintenance"

all depend on manual work.For this reason

Sichuan Electric Power Corporation takes up with integrative network management system since 1990s to implement a new mechanism of centralized control

management and maintenance.But

the obturation of maintenance port and decentralization of interface protocol provided by equipment supplier make integrative network management system impossible to implement.So it keeps away from physical layer

and achieves integrative network management function mainly at protocol layer using "integrative network alarm collecting system".
