Electronic fence alarm system

Abstract

The invention discloses an electronic fence alarm system. The system comprises a plurality of stainless steel wire ropes, a plurality of wire rope fixing devices, a plurality of high-strength insulating ceramic terminals, a plurality of tension detection devices, a main tension control board and a high-voltage generating device, wherein, the plurality of the stainless steel wire ropes are sequentially and alternately arranged from the top down and are connected in series through high-voltage leads; the plurality of the wire rope fixing devices are respectively connected on two ends of each stainless steel wire rope; two ends of each wire rope are respectively and sequentially connected with one wire rope fixing device and one high-strength insulating ceramic terminal, the high-strength insulating ceramic terminal on one end is arranged on a support bar, and the high-strength insulating ceramic terminal on the other end is connected with one tension detection device; the tension detection devices are fixedly arranged on the other support bar and are connected with the main tension control board; and the main tension control board is connected with the high-voltage generating device, is used for receiving and processing a tension signal, and controls the high-voltage generating device to generate high-voltage pulse in case of an alarm. The electronic fence alarm system has an active defense function without blind spots in perimeter precaution; and the system is adapted to various complex terrain environments without precaution dead space, thus being widely applicable to all places in need of perimeter precaution.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to an electronic fence alarm system for perimeter protection and alarm. Background technique [0002] It is required in ordinary residential areas, villa residential areas, enterprises and institutions, factories, warehouses, substations, water plants, power plants, schools, 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 intrusion alarm system. [0003] For civilian perimeter protection and alarm systems, infrared detection technology and infrared microwave double-detection technology are generally used, but these technologies have the disadvantage of high false alarm rate. [0004] Chinese Utility Model Patent Specification CN2703088Y (authorized announcement date: on June 1, 2005) discloses a kind of " intelligent electronic fence ", but, ...

[0003] For civilian perimeter protection and alarm systems, infrared detection technology and infrared microwave double-detection technology are generally used, but these technologies have the disadvantage of high false alarm rate

[0004] Chinese utility model patent specification CN2703088Y (authorized announcement date: June 1, 2005) discloses a kind of "intelligent electronic fence", but the intelligent electronic fence can only detect the alarm when it is cut

[0005] Chinese invention patent application publication specification CN101520933A (disclosure date: September 2, 2009) discloses a "heartbeat detection electronic fence sensor system and detection method", Chinese invention patent application publication specification CN101582189A (disclosure date: November 2009 On the 18th, a "tension-type electronic fence perimeter anti-intrusion alarm system" was disclosed. The above two inventions belong to the prevention and alarm system for passive detection of the perimeter, without the function of active defense.
