长输热网光纤监测系统工程应用

Engineering Application of Optical Fiber Monitoring System for Long-distance Heat-supply Network

结合某长输热网项目,介绍光纤监测系统的实际应用。光纤监测系统主要包括监测子系统、风光互补发电站、监控中心。监测子系统包括:分布式光纤感温测漏系统、光纤井盖防盗系统、分布式光纤测振系统,分别用于供热管道泄漏监测、热力井盖防盗、供热管道防挖掘。风光互补发电站主要为供热管道隧道内空气质量监测装置提供电源。监控中心用于实现数据显示与监测、故障预警与定位等功能。

Combined with a long-distance heatsupply network project,the practical application of optical fiber monitoring system is introduced.The optical fiber monitoring system includes monitoring subsystem,wind and solar hybrid power station and monitoring center.The monitoring subsystem includes distributed optical fiber temperature sensing and leakage measuring system,optical fiber manhole cover anti-theft system and distributed optical fiber vibration measuring system.They are used separately for monitoring leakage of heating pipeline,preventing theft of the heating manhole cover and preventing excavation of heating pipeline.The wind and solar hybrid power station mainly provides power for the air quality monitoring devices in heating pipeline tunnel.The monitoring center is used to realize the functions such as data display and monitoring,fault warning and positioning.
