The invention discloses an intelligent fiber perimeter intrusion alarm system, and the system includes a vibrating cable, a wire mesh, a Y-shaped bracket, a rolling cage barbed wire, a fiber perimeterintrusion detector, a linkage module, a network hard disk recorder, an industrial switch, a fiber optic transceiver, a high-definition network dome, a sound and light alarm, a loudspeaker and an upper computer. Among them, the vibrating cable is hung on a fence or a wall in a ring-shaped manner, and is arranged underground in a sinusoidal manner to realize the detection of an intrusion behavior,and an optical signal with the vibration information is transmitted to the fiber perimeter intrusion detector through an artificial neural network for processing. After the intrusion behavior of a person or a vehicle, the local high-definition network dome camera is controlled by the linkage module, the network hard disk recorder, the industrial switch and the optical transceiver to perform videorecording and expelling through the loudspeaker. Meanwhile, the sound and light alarm is used to alert the user, thereby achieving the local user monitoring.
