AN INTRUDER DETECTION SYSTEM FOR FENSE SECURITY USING A WIRE WHEEL MECHANISM

摘要

An intrusion sensing system for fence security based on the wire wheel method is provided to minimize the maintenance cost. An intrusion sensing wire(103) is installed between security posts(101) for the intrusion sensing of a fence. The intrusion sensing wire is connected to the security posts and an intrusion sensing slave(105). A wire wheel module is connected to the intrusion sensing wire and includes a windup spring for maintaining the tight state of the intrusion sensing wire. The wire wheel module detects the rolled state or unlaced state of the intrusion sensing wire. The intrusion sensing slave outputs the state data in the state that an address provided from an intrusion sensing master coincides with a preset intrinsic address.
