摘　　要：介绍了一种基于STM32微控制器并能够进行远程、实时监测的多通道裂缝位移监测系统。系统包括采集节点和监测中心两部分,采集节点以STM32微控制器为核心,采用线性位移传感器获取裂缝位移信息,经过多通道选择电路、信号调理电路后被STM32微控制器采集、存储进本地U盘,并通过无线传输模块将采集到的数据发送到监控中心;通过采集软件接收采集节点发送的数据,并存储进本地硬盘中。最后通过室内模拟实验和野外应用试验,验证了研制的多通道裂缝位移监测系统工作稳定、可以应用于野外裂缝的实际监测中。A multi-channel crack displacement monitoring system based on STM32 is proposed in this paper,and the system can achieve the aim of remote,real-time monitoring for crack displacement.The system includes two parts： the acquisition node is using STM32 micro-controller as its core,uses the linear position sensors to get the crack displacement,and then the displacement signal passes to the multi-channel choose circuit and the signal processing circuit,finally STM32 micro-controller collects the signal and stores it into local U disk,and also transmits the data to the monitoring center through the wireless transmission module at the same time.The monitoring center receives the data which come from the acquisition node through the acquisition software and then stores the data into local hard disk.At last,this paper presents a simulation experiment and field application experiment,and the result indicates that the instrument can stable work and can be applied to the actual monitoring of field cracks.
