Intelligent fiber perimeter intrusion alarm system

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of perimeter security monitoring, in particular to an intelligent optical fiber perimeter intrusion alarm system. Background technique [0002] Security and monitoring systems not only play an important role in people's daily life, but also have obvious advantages in the application of key area protection such as banks, prisons, and border defense lines. The traditional manual inspection not only wastes a lot of manpower and material resources, but also has a small per capita monitoring range, making it difficult to achieve real-time monitoring. Solutions such as infrared and laser beams are easily affected by natural climates such as high and low temperature, rain, snow and fog, and are easy to be crossed or avoided. The sensing part of the leakage cable or vibration cable is active, and the system consumes a lot of power. When the monitored area is large, the cost of the system itself and the operation an...

Problems solved by technology

This patent only describes the method of installing the optical cable on the fence for overcoming intrusion and cutting position identification, but does not describe the identification and filtering of environmental interference behavior, nor does it describe the perception and identification of ground intrusion behavior
