Security operation management system for substation

The invention discloses a security operation management system for a substation. The system comprises at least one mobile terminal, at least four fixed nodes, a front-end processor and a monitoring host, wherein the mobile terminal is carried by a worker of the substation; the fixed nodes are arranged in the vicinity of electrical equipment of the substation and dangerous intervals or working intervals, and are connected with one another by a transmission protocol; the mobile terminal is connected with adjacent fixed nodes by the transmission protocol, and forms a wireless sensor network with the fixed nodes; the fixed nodes comprise a master node which is connected with the front-end processor by the transmission protocol; and the front-end processor is connected with the monitoring host by a communication interface. The system can monitor and rapidly accurately position the current location of the worker of the substation by the wireless sensor network, gives an alarm and a prompt when the worker mistakenly enters a dangerous area or a protective area or travels along a wrong path, and has the advantages of moisture resistance, rain resistance, sun protection, rust protection, high anti-jamming capability, low power consumption, energy saving and the like.
