摘要
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 sensor 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.
