Research And Implementation Of New Perimeter Alarm Detection System Based On Leakage Coaxial Cable

This article takes the actual project "leakage coaxial cable of new perimeter alarm detection system" as background, designed a kind of new perimeter alarm detection system based on leakage coaxial cable.At present the commonly used perimeter alarm detection system has high cost, poor hidden shortcomings generally. It not only achieves a high accuracy and hidden installation, but also makes the cost a dramatic decline, when using leakage coaxial cable as induction devices.This paper does an in-depth research on the working principle of leakage coaxial cable, and systematically analyses the leakage coaxial cable operation frequency-band, coupling loss, radiation loss and transmission loss properties, and the relationship between coupling loss and radiation loss, and conducts a simulation analysis of the radiation field.This paper analyses and designs a new kind of perimeter alarm detection system using leakage coaxial cable as induction devices. This perimeter alarm detection system can automatically control its working station depending on the different climate and the installation terrain, and has an effective intelligent pattern judgment to the personnel, or different objects invasion. The detection system has confidentiality, the electromagnetic wave three-dimensional space guard, all-weather working, intelligent mode processing, environment auto-adapting, ultra long border linkage and system linkage, high reliability characteristics, etc.This paper tests the function of the perimeter alarm detection system, including the system inspection, the system commissioning, walk test, tamper alarm test, broken cable alarm test, resistance of small animals interference test, data acquisition test, clock accuracy test, data display test, status display test, data communication test, event log test, data retention test, password protection test and the recovery test, on which this paper does routine test function test, the electromagnetic compatibility tests, safety test, and mechanical properties test of the perimeter alarm detection system on. The test results show that the designed detection system meeting the design requirements. The detection system has been put into using.
