Abstract

The invention discloses an optical fiber intelligent monitoring system and a monitoring method based on a phase signal carrier technology. The optical fiber intelligent monitoring system comprises two-core closed-loop inducting optical cables distributed in an inducting area, an optical package, a signal processing unit and a personal computer (PC) host computer. Signals inducted by the two-core closed-loop inducting optical cables are transmitted to the PC host computer sequentially through the optical package and the signal processing unit. The optical package carries out light splitting and modulation to the optical signals, the two-core closed-loop inducting optical cables generate two lines of interference lights to external inductions, and the interference lights are processed through the signal processing unit and sent to the PC host computer, and alerting signals are generated after the signals are analyzed. And therefore the purposes of high sensitivity, large detecting range and short response time are achieved.

Description
