为了满足当前位移测量系统对于微小位移进行稳定可靠和精确测量的需求,文中提出了一种基于STM32的嵌入式光纤束微位移传感器的设计方案。该光纤束位移传感器主要利用了光强调制型的工作原理,以STM32F103ZET6为核心,采用设计的光纤束微位移传感探头对微位移进行准确测量,软件部分实现了两路检测信号相除、线性化处理和温度补偿等工作,同时将采集的位移数据通过串口实时发送至上位机,实现了对温度数据的动态显示,查询、储存等功能。该传感器具有成本低、测量精度高、操作简单等优点,可以在各种复杂的工业现场高效而准确地对各种微位移进行精确测量。

In this paper,aiming at the requirement of high-accuracy measuring of micro-displacement,an embedded optical-fiber bundle micro-displacement sensor was proposed based on the STM32 processor. The sensor using the working principle of lightintensity optical fiber bundle displacement sensor,took STM32F103ZET6 as the core. Optical fiber bundle sensor was used to measure micro-displacement. The micro-displacement data collected by the software were used to accomplish linearized processing and temperature compensating,and transmitted to host computer which implemented functions of data active display,query and storage.The micro-displacement sensor exhibits the features of low-cost,high detecting precision and convenient to operation,and also can be widely used to detect various micro-displacement in industrial environment.
