Anti-intrusion nuclear power station electronic fence capable of accurately positioning intrusion site

The invention provides an anti-intrusion nuclear power station electronic fence capable of accurately positioning an intrusion site, and the fence comprises a physical fence layer which comprises a plurality of basic fence units and is used for the physical blocking of a foundation; and the sensing detection layer comprises a plurality of sets of sensing detection units and a central control unit, and the sensing detection layer is arranged on the physical fence layer and is used for detecting whether an intrusion behavior exists or not and determining an intrusion site. The sensing detection unit comprises a basic sensing assembly, a sensing reaction assembly and a trigger circuit assembly, and the sensing detection layer is configured in a way that in a first state, the trigger circuit assembly is triggered, and the central control unit starts to detect whether an intrusion behavior exists or not; and in the second state, the central control unit finally determines the existence of an intrusion behavior and
