Perimeter Protection Alarm System and Line Displacement Detector Using Line Displacement to Detect Intrusion

Abstract

The invention relates to a perimeter protection alarm system utilizing linear displacement to detect invasion and a linear displacement detector. The alarm system comprises a linear displacement detection unit, a linear displacement coding unit, a linear displacement video linking unit, a linear displacement transmitting unit and a linear displacement control host machine. During use, the linear displacement detector of the linear displacement detection unit is mounted on a net fence of the perimeter; when the net fence is invaded, the linear displacement detector outputs an alarm signal to the linear displacement coding unit; the linear displacement coding unit processes the alarm signal, and outputs an alarm encoded signal; the linear displacement video linking unit receives the alarm encoded signal, and sends the alarm encoded signal to a tripod head and the linear displacement control host machine; the tripod head is rotated to an alarm point for monitoring and camera shooting according to preset position arrangement and the alarm encoded signal; a camera transmits a video signal of the alarm point to a hard disk video recorder through the linear displacement transmitting unit. Invade re-check is conducted through the monitoring video, so that an effective perimeter protection function is played.

Description

technical field [0001] The invention belongs to the technical field of perimeter protection and alarm, and in particular relates to a perimeter protection alarm system and a line displacement detector for detecting intrusions by using line displacement. Background technique [0002] With the continuous progress of society, rapid economic development and rapid technological advancement, people pay more and more attention to public order safety, production safety and property safety, and safety monitoring systems are widely used in various industries. [0003] At present, there are more and more types of monitoring systems on the market, especially video monitoring systems are the most widely used in monitoring applications. Not only does it need to connect multiple cameras to cover the entire area, which greatly increases the cost of the monitoring system; in addition, people or vehicles passing through the fence of the perimeter protection zone are not in the protection zone...

Problems solved by technology

[0003] At present, there are more and more types of monitoring systems on the market, especially video monitoring systems are the most widely used in monitoring applications. Not only does it need to connect multiple cameras to cover the entire area, which greatly increases the cost of the monitoring system; in addition, people or vehicles passing through the fence of the perimeter protection zone are not in the protection zone, but enter the warning area of ​​the monitoring system. It will cause the alarm of the video surveillance system and increase the false alarm rate
