摘要
鉴于传统温度传感器受到周围环境因素的影响较大,系统采用抗干扰能力强和对温度极其敏感的光纤布拉格光栅(FBG)传感器。光信号通过该传感器进行传输和测量,实现现场的无电监测。系统以数字信号处理器TMS320F2812为核心,分析了光纤光栅传感器的结构原理和光纤光栅解调系统,介绍了系统硬件组成和软件实现。实验结果表明该系统温度测量精度较高,适用于中、小型电力变压器的监测和保护。
The traditional temperature sensors are impacted greatly by environmental factors.The system used fiber Bragg grating（FBG）sensor with anti-jamming capability and extremely sensitive to temperature.Optical signal transmits through the sensor to achieve monitoring.The system took digital signal processor TMS320F2812 as the core.The paper analyzed the structural principle of fiber Bragg grating sensor and its demodulation system,introduced the hardware components and software implementation.The experimental results show that the high accuracy temperature measurement system is fit for small and medium power transformer＇s monitoring and protection.
