Multi-level large-span large data oriented power equipment state monitoring and evaluating system

The invention discloses a multi-level large-span large data oriented power equipment state monitoring and evaluating system. The system is divided into four levels: an acquisition and convergence level, a station control layer, a provincial network level and a headquarter level. The acquisition and convergence level is further divided into a convergence sub-system and an acquisition sub-system. The station control level comprises a state monitoring server, a working station, a mobile terminal accessing device and a mobile terminal. The state monitoring server saves data of gateway transmission and is connected with the working station and the mobile terminal accessing device through an Ethernet. According to the invention, the advanced wireless sensor networking technology is organically combined with a power equipment state monitoring system, which realizes the full digitalization and integrated informationization from a primary power equipment terminal to a provincial headquarter level.
