Multiple-wire-system tension electronic fence intrusion detector and detecting method

Abstract

The invention discloses a multiple-wire-system tension electronic fence intrusion detector and a detecting method. The detecting method comprises: step one, performing adjustment from a one wire system to an eight-wire system of a tension electronic fence and presetting warning upper and lower threshold values of the wire systems; step two, detecting tension change of the tension electronic fence to obtain a tension value characteristic and generate a tension voltage signal; step three, circularly sampling the tension voltage signal in real time and amplifying a sampled tension voltage signal; and step four, converting the amplified tension voltage signal into a digital signal to perform analysis and judgment, comparing the digital signal and the preset warning upper and lower threshold values and judging whether warning is performed or not. The multiple-wire-system tension electronic fence intrusion detector and a detecting method can achieve adjustment from the one wire system to the eight-wire system of the tension electronic fence according to a field environment defense area and greatly facilitate user usage. Various different types of intrusion situations on the tension electronic fence can be detected, and warning is accurately positioned.

Description

technical field [0001] The invention belongs to the technical field of electronic communication and relates to a detector, in particular to a multi-wire tension electronic fence intrusion detector and a detection method. Background technique [0002] In recent years, with the continuous expansion of market application prospects, various safety and precautionary technical measures have emerged, such as in ordinary residential areas, villa residential areas, enterprises and institutions, factories, warehouses, substations, water plants, power plants, schools, and As for the detention centers and prisons of the judicial system, as well as airports, military bases, government agencies, key cultural relics protection units and other places, perimeter security and perimeter anti-intrusion alarm facilities are required. With the increasing demand for safety protection, the safety protection system of various new detection technologies has developed rapidly, and the perimeter protec...

AI Technical Summary

Problems solved by technology

[0003] For the perimeter anti-intrusion alarm system, infrared detection technology and infrared microwave double-detection technology are generally used for detection. The main products are infrared intrusion detectors and infrared gratings, but these infrared detection products have higher requirements on the environment. When the environment changes, such as tree branches, strong light, animals coming in and out, or heavy wind and rain, it is easy to generate false alarm information, and the false alarm rate is high

[0004] The commonly used perimeter protection product is the high-voltage pulse tension electronic fence, which uses high-voltage, low-energy pulses. Although it will not cause direct harm to the human body, if it is accidentally touched, it may cause a strong electric shock. Indirect injuries such as falling; sometimes electric sparks are generated, so it is not suitable to use in an environment with flammable gas, and it is necessary to keep a sufficient distance from the power line

[0005] The traditional tension electronic fence has both blocking and alarm functions. The exposed mechanical parts are not charged, and will not cause direct or indirect damage to the human body. It is safer and more reliable to use. It is a green electronic fence, but its defense area is not adjustable. Not suitable for harsh environments, inconvenient for installation and debugging
