Tension type electronic fence periphery intrusion preventing alarm system

Abstract

The invention discloses a tension type electronic fence periphery intrusion preventing alarm system which comprises a tension type electronic fence consisting of a fence, a tension detection device and a communication device, wherein the fence comprises a stainless steel rope and a fixing device of the steel rope; the tension detection device is mechanically connected with the steel rope and is used for detecting the tension characteristic of the steel rope and transmitting detected signals to the communication device; and the communication device is used for receiving the output of the tension detection device, generating alarm signals, providing a remote transmission bus interface and a defensive area address, and transmitting the alarm signals to a management center through a transmission control device and a bus transmission wire. The invention integrates an entity protecting facility and an alarm device, responds intrusion attempts by climbing, pulling and pressing, shearing the steel rope of the fence according to the tension characteristic of the steel rope of the fence, generates the alarm signals, has stable and reliable performance, is suitable to various complex landforms and environments without precaution dead angle, and is widely applied to all occasions requiring the periphery precaution.

Description

technical field [0001] The invention relates to a security technology prevention and alarm system, in particular to a tension-type electronic fence perimeter anti-intrusion alarm system used in places where perimeter security is required. Background technique [0002] In ordinary residential areas, villa residential areas, enterprises and institutions, factories, warehouses, substations, water plants, power plants, schools, as well as detention centers and prisons in the judicial system, as well as airports, military bases, government agencies, key cultural relics protection units, etc. All sites require perimeter security and perimeter anti-intrusion alarm facilities. For civilian perimeter anti-intrusion alarm systems, 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 ...

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 not knowing the static force of the fence wire rope, whether the wire rope is pulled too tight or too loose, therefore, it is difficult to guarantee the stability and reliability of the alarm threshold
