RCC坝温度监测光纤传感网络设计与埋设工艺研究

Design of Optical Fiber Senor Network for Temperature Monitoring and Research on Its Embedded Technology in the RCC Dam

将基于分布式光纤温度监测系统的工作原理和测量方法,应用于百色水利枢纽工程中,对光纤监测网络的设计方法进行了探讨,并对光纤的埋设工艺进行研究。分布式光纤温度监测系统实现了每1.0m1个读数点的连续测温,较好地获得了RCC温度分布情况,与传统监测仪器的对比表明,分布式光纤温度监测系统是可靠和精确的。

Based on the theory of Distribute Temperature System and the method of measurement, the system is applied in the Baise Water Control Project. The techniques of optical fiber network are discussed, and then the embedded technology is studied. Distribute Temperature System can measure the dam＇ s temperature every 1 meter along the optical fiber. Through it, the temperature field of RCC dam is clearly known. The results of the temperature monitoring show that DTS is reliable and correct by comparing the resuhs of the traditional instrument.
