Network environment security sensing system and method for power distribution terminal

The invention discloses a network environment security sensing system for a power distribution terminal. A terminal security management server formulates sensing component information acquisition configuration and monitoring strategies according to different terminal types and issues the sensing component information acquisition configuration and monitoring strategies to each regional relay node; after receiving the information, each relay node forwards the information to an environment sensing component embedded in each type of power distribution terminal in the jurisdiction area; after receiving the information, the environment sensing component starts to execute a task in the information and feeds back an execution result to the relay node; and the relay node aggregates and screens the execution results of all the power distribution terminals and feeds back the screened structure to the terminal security management server, and the terminal security management server processes the results and gives an alarm
