摘　　要：针对现有锚杆受力监测方法存在的结构复杂、测点单一、安装不便等问题,设计了基于同步监测的锚杆受力监测系统。该系统选用扩散硅压力传感器采集巷道某一断面的锚杆轴向力,可同时获取8根锚杆的受力数据;将采集的数据进行分压滤波、AD转换后,存储并传输。实验结果表明,该系统实现了对巷道某一断面多根锚杆、锚索的高采样率同步监测,测量精度可以满足断面锚杆受力同步监测的要求。In view of problems of complex structure,single measuring point and inconvenient installation of existing bolt force monitoring method,a bolt force monitoring system based on synchronous monitoring was designed.The system selects the diffusion silicon pressure sensor to collect the axial force of the bolt in a certain section of the roadway,and the force data of 8 bolts can be obtained simultaneously;the collected data are stored and transmitted after partial voltage filtering and AD conversion.The experimental results show that the system realizes synchronous monitoring of multiple bolts and anchor cables in a certain section of the roadway with high sampling rate,and its measurement accuracy can meet requirements of synchronous section bolts monitoring.
