Accurate Positioning Alarm Device YX-ZD-B
查看大图

I. Overview

Based on the advanced M-Z interference theory, the accurate positioning smart optical fiber sensing alarm system adopts our independently developed bidirectional positioning technology and constitutes a two-way link structure composed of accurate positioning optical fiber sensing alarm host machine, optical processing module, optical fiber and optical loop module. With a monomode armored cable laid along the perimeter or pipeline, the system can differentiate third-party intrusion from normal interference through special algorithm, analysis and processing of the alarm controller. In response to intrusions within a radius of 110 Km, the system will trigger an alarm and accurately tell the location of intrusion (10-100 meter positioning) in latitude and longitude, bridging the gap of Chinese market in this regard. 



The system is particularly suitable for long-distance perimeter security protection of petroleum and natural gas fields, all kinds of pressure pipes, communication optical cables, power cables, military border defense areas.
