Safety protection wall and detectors

Abstract

The invention discloses a safety protection wall. The safety protection wall comprises a plurality of detector groups disposed in a safety protection area, and wireless signal transceiving is carried out among detectors of every detector group, and therefore wireless signal radiation areas are formed. A plurality of wireless signal radiation areas are superposed with each other, and a continuous and seamless microwave array is formed in the safety protection area. When an invader breaks in the safety protection area, the wireless signal disturbance of the microwave array is caused, and the invader in the safety protection area is monitored according to the signal disturbance. Detection results are acquired after recombining a plurality of relatively independent wireless signals of the same position by adopting multiple-transmitting and multiple-receiving of a plurality of detectors, and then the detection results of a plurality of detectors are verified by each other, and the verification process is not just simple superposition between and and or of processing results of an upper layer, but is the processing and the calculation of the detection results of the detectors on a bottom layer, and therefore influences of disturbance factors on the detection results are effectively filtered, and the accuracy of the detection results is improved.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a security protection wall and a detector. Background technique [0002] The security protection system refers to the defense system that guards against the border of a certain area or calls the police when the border is invaded by foreign things. The safety protection system has gradually developed from the initial purely physical protection measures (such as fences and walls) to the current comprehensive safety protection system that combines physical defense, technical defense, and human defense. [0003] At present, the common technical prevention schemes mainly include: infrared intrusion detection, leakage cable intrusion detection and vibrating optical cable intrusion detection. Infrared intrusion detection mainly uses invisible light beams (infrared rays) to form a warning line between the transmitter and receiver, and adopts the method of blocking the alarm to form a ...

AI Technical Summary

Problems solved by technology

[0004] There are blind spots in the protection zone of the existing security system, which are easy to be crossed, have a low degree of safety, and are easily affected by the external environment (such as rain and snow, animals and plants, etc.) and cause false alarms, which have higher requirements for the installation environment
