Intelligent vibration electronic fence and perimeter anti-intrusion alarm system

Abstract

The invention provides an intelligent vibration electronic fence, which comprises a fence, a vibration detection device and a communication device, wherein fence is provided with a metal wire and a metal wire fixing device; the vibration detection device is not connected with the metal wire and is used for detecting the vibration characteristics of the metal wire and sending a detected signal to the communication device; the communication device is used for receiving a detecting signal of the vibration detection device, providing a remote transmission bus interface and a defense zone address for a generated alarm signal, and sending to a management center through a bus transmission line. The intelligent vibration electronic fence is an aggregate of an entity protection facility and the alarm system. According to the vibration characteristics of the metal wire of the fence, the fence makes a response to attempted intrusion behaviors of climbing, pulling, pressing and shearing stainless steel wire ropes of the fence and generates an alarm signal. The performance is stable and reliable. The fence is suitable for various complicated terrain environments, and no prevention blind-angle is left. The fence is widely suitable for all places having perimeter prevention needs.

Description

technical field [0001] The invention relates to a security alarm system, in particular to an intelligent vibrating electronic fence alarm system suitable for perimeter security sites. Background technique [0002] In ordinary residential areas, villa residential areas, enterprises and institutions, factories, warehouses, substations, water plants, power plants, schools, and judicial system detention centers, prisons, airports, military bases, government agencies, key cultural relics protection units and other places Both require perimeter security and perimeter anti-intrusion alarm facilities. For civilian use, infrared detection technology or infrared microwave double-detection technology is generally used for detection, but both have the disadvantage of high false alarm rate. Some judiciary and military perimeter anti-exceeding facilities use high-voltage power grids. The disadvantage is that high-voltage power grids may pose a threat to the lives of illegal trespassers. ...

AI Technical Summary

Problems solved by technology

One of the disadvantages is that we do not know the magnitude of the force of the intruder pulling the fence cable and decide whether to alarm according to the magnitude of the force, and it is even more impossible to change the alarm threshold according to actual needs

The second disadvantage is that it is difficult to guarantee the stability and reliability of the alarm threshold without knowing the static force of the fence wire rope and whether the wire rope is pulled too tight or too loose.
