An intrusion sensing system for fence security based on the wire sensor method is provided to prevent the damage of security facilities by connecting an intrusion sensing wire to a spring. An intrusion sensing wire(103) is used to connect security posts(101) for the intrusion sensing through a fence. A spring(109) provides the tensile force for maintaining the tight state of the intrusion sensing wire. An intrusion sensing slave(105) consists of an intrusion sensing sensor and an intrusion sensing slave controller. The intrusion sensing sensor senses the motion of the intrusion sensing wire. The intrusion sensing slave controller outputs the state of the intrusion sensing sensor in the state that an address referred by an intrusion sensing master coincides with a preset intrinsic address.
