Method for implementing system maintenance in security network

The invention discloses a method for implementing system maintenance in a security network, which comprises a central server and front-end devices; the method is mainly used to automatically maintain each device in the security network and give early warning on faults, so that the devices can operate under more support. The main method is as follows: the central server automatically acquire the CPU occupation rates, memory occupation rates, internal temperatures, device alarm frequencies and the like of the front-end devices (including industrial control type hard disk video cassette recorders, embedded hard disk video cassette recorders, IP cameras, video servers, alarm devices and the like) and central devices (including all server devices accessing the network), and according to intelligent analysis conditions, the devices are divided into normal devices, dangerous devices, highly dangerous devices, faulty devices and the like. According to the alarms of different devices, a user carries out remote mainten
