摘要
该文提出了一种基于STM32单片机的便携式光纤光栅解调仪设计方案,以STM32F103作为核心控制器,对光纤光栅中心反射波长的微小偏移进行精确测量,并将之转换为相应物理量。STM32单片机使用TTL/CMOS与迪文DGUS触摸屏进行交互,实现对反射波形的显示、波长计算及数据处理等,可方便地进行光纤光栅传感数据的测读。
A design scheme of portable fiber grating demodulator based on STM32 MCU is proposed.It uses STM32F103 as the core controller to accurately measure the small offset of the reflection wavelength of the fiber grating,and converts it into a corresponding physical quantity.STM32 MCU uses TFL/CMOS to interact with Devin DGUS touch screen to achieve the reflection of the waveform display,wavelength calculation and data processing. It can be easily carried out fiber Bragg sensing data.
