Passive detection defense fence

Abstract

A passive detection defense fence comprises a fence body, limiting blocks, passive sensors, trigger components and stress rods. The fence body comprises supporting rods and a plurality of handrails; the handrails are arranged between two sets of supporting rods side by side at equal intervals; two ends of the stress rod are slidably arranged at the top of the supporting rod in the vertical direction. The limiting block is arranged at the top of at least one handrail; the upper part of the passive sensor is arranged at the bottom of the stress rod; the passive sensor is connected with an anti-shearing line, and the anti-shearing line is arranged in the handrail and used for sending a shearing signal to the passive sensor; the trigger component is arranged at the top of at least one handrail. The equipment is convenient to install, a large number of construction wiring cables are saved, power supply is not needed, manpower and material resources are saved, and the detection defense effect is achieved; the equipment can inform security personnel of an intrusion situation at the first time, so that emergency situations can be dealt with conveniently; the equipment improves the quality function of the equipment on the basis of an inherent defense means, improves the safety and flexibility, and does not need to consider electromagnetic interference.

Description

technical field [0001] The invention relates to the field of detection defense fences, in particular to a passive detection defense fence. Background technique [0002] At present, the domestic detection and defense fence industry is all electronic detection type that needs power access, relying on electronic or optical sensors to drive the product to alarm, as long as the product is connected to the power supply, there are still potential safety hazards, and the detection and defense fence The built-in mechanical structure cannot be built with conventional springs through durability testing. Ordinary fences and existing electronic detection fences cannot achieve the alarm deterrent effect played by special occasions (such as electromagnetic environment sensitivity, radiation environment, gravity failure environment, etc.). All of the above issues need to be resolved. Contents of the invention [0003] (1) Purpose of the invention [0004] In order to solve the technica...

Problems solved by technology

[0002] At present, the domestic detection and defense fence industry is all electronic detection type that needs power access, relying on electronic or optical sensors to drive the product to alarm, as long as the product is connected to the power supply, there are still potential safety hazards, and the detection and defense fence The built-in mechanical structure passed the durability test and cannot be built with conventional springs

Ordinary fences and existing electronic detection fences cannot achieve the alarm deterrent effect played by special occasions (such as electromagnetic environment sensitivity, radiation environment, gravity failure environment, etc.)
