摘　　要：介绍了一种基于DFB激光器和光纤光栅传感器多路测温系统的详细设计方案。分析了多路光纤光栅传感器测温的结构及其工作原理,并以STM32F107VCT6和AD7606为主控板核心,给出了该系统软件控制过程和硬件电路设计。实践表明,该系统测温精度高、测温范围广、使用方便、抗电磁干扰能力强、成本低、体积小,可以广泛用于各种电力系统设备多点测温。The paper introduced the design method of multi-channel temperature demodulate system based on DFB （ Distribu- ted Feedback） laser and fiber grating sensor, analyzed the structure and work principle of multi-channel fiber grating sensor for tem- perature measurement, and realized the software control process and the hardware circuit design with STM32F107VCT6 and AD7606 as the main control board cores. Practice show that this system has so many strong advantages, such as the high measure- ment precision and wide t scope, the convenient usage, the strong anti-electromagnetic capability, the good stability when communicating data and low cost. It can be widely used for multi-point temperature measurement in various electric systems
