Portable radar perimeter security and protection system

Abstract

The invention provides a portable radar perimeter security and protection system. The portable radar perimeter security and protection system comprises radars, first control boxes, a numerical control linkage dome camera, a second control box, a server, a displayer of the server, a switch, a monitoring video display device and an alarm device. The server, the numerical control linkage dome camera, the wireless equipment, the radars, the monitoring video display device and the alarm device are connected by the wireless network. The server is equipped with the portable perimeter security and protection system software; the core of the software is the control of 3D linkage of the radars and the numerical control linkage dome camera; the algorithm adopted by the linkage control is presetting the space coordinates of the left, center and right 3 points of the radars and the numerical control linkage dome camera, and the input data is the target location detected by the radars, and the calculating result which is calculated according to trigonometric function is the PTZ 3D coordinate of the numerical control linkage dome camera. The first control boxes are used for supplying power to the radars, and the second control box is used for supplying power to the numerical control linkage dome camera. The switch provides the connection ports for a plurality of cables, used for connecting the server, the monitoring video display device, and the numerical control linkage dome camera; and the switch adopts star topology and realizes the data exchange among the devices in the network.

Description

technical field [0001] The invention relates to a security system, in particular to a portable radar perimeter security system. Background technique [0002] The perimeter alarm system is an alarm system, which is an alarm trigger system composed of perimeter alarm detectors, alarm hosts, and transmission media. In recent years, as people pay more attention to their own personal and property safety, perimeter alarm, as an integral part of security alarm, has also been valued by the majority of security engineering companies and end users, and more and more people pay attention to perimeter alarms. The principle of the perimeter alarm is mostly: the front end of the detector senses the alarm information, if someone invades and triggers the alarm, the perimeter alarm detector will transmit the detected alarm signal to the alarm host, and the alarm host will send an alarm through the linkage device or sound The device prompts the front-end alarm. [0003] For industrial sites...

AI Technical Summary

Problems solved by technology

[0007] The main defects of the portable video surveillance system are: equipment installation is cumbersome, cable transmission is required, the intrusion point cannot be actively located, the detection range is small, and it is greatly affected by weather and light; the reliability of the alarm algorithm is low

[0011] 2. The protection range is small

Due to the straight-line propagation characteristics of infrared / laser, portable optical security systems can only establish a very limited detection area, which is easily crossed by intruders;

[0012] 3. No ranging capability

Restricted by factors such as lens, camera field of view, and camera pointing, video technology cannot provide real-time, full-area monitoring. Image recognition and automatic tracking and alarm technology has great limitations, and large outdoor monitoring cannot yet be realized.
