传统温度传感器受到周围环境因素的影响很大,系统采用抗干扰能力强并且对温度极其灵敏的光纤光栅传感器.利用光信号的测量和传输,再解调成温度信号.分析了光纤光栅传感器的原理和系统构成,介绍了软件和硬件的实现.最后的实验结果证明了系统具有较高的测量精度,可满足变压器绕组高精度温度测量要求.%Surrounding environment factors have great impacts on traditional temperature sensors. The system uses fiber bragg grating (FBG) sensor with anti-jamming capability and temperature sensitivity. The system measures and transmits optical signals, which are demodulated to temperature signals. The paper analyzes the principles and structure of fiber bragg grating sen-sor and introduces the implementation of hardware components and software. The experimental results show that the system has high accurate measurement, which meets high precision requirements of transformer winding temperature.
