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.
