摘　　要：针对大坝安全监测的技术要求,设计并研制了一套基于铅垂线原理的大坝水平位移测量系统。该系统以光栅尺、激光发射和接收器、减速电机为主要运动部件,以性能强大的ARM内核芯片为主控制器,采用大屏幕LCD为人机交互界面,实现对大坝水平横向和纵向的精确测量。该系统还具有人工手动实时测量、定时自动测量的功能,可以通过485总线上传测试结果到总控制中心进行显示和分析。实验结果表明,该系统具有精度高、成本低、误差小的优点。In view of technical requirements for dam safety monitoring, a dam horizontal displacement monitoring system is developed based on a principle of plumb line. The system takes grating ruler, laser transmitter and receiver, gear motor as the main moving parts, adopts powerful ARM kernel chip is adopted as micro-controller, the large screen LCD is used for human-computer interaction interface. The device can achieve accurate measurement of transverse and longitudinal axis of the dam. The system also has functions of manual real-time measurement and automatic measure- ment, and can upload test results through the 485 bus to the control center for display and analysis. The experimental re- suits show that the equipment has the advantages of high precision, low cost and small error.
