摘　　要：针对现有垂线坐标仪存在只能测量一个方向的位移变化的问题,设计了一种基于CCD的三维垂线坐标仪,给出了仪器的组成及测量方法;详细介绍了仪器平行光源电路及基于CPLD的CCD时序驱动电路设计。试验结果表明,该仪器工作稳定,数据处理方便快捷,实现了对由井壁变形造成的水平和竖向位移的精确测量。In order to solve the problem that existing vertical plumb line coordinator can only measure displacement change in one direction,a 3D vertical plumb line coordinator based on CCD was designed.Composition and measurement method of the instrument were given,and circuits of parallel light source and CCD timing drive based on CPLD were introduced in details.The experiment result shows that the instrument is stable,fast and convenient for data processing,so as to realize accurate measurement of horizontal and vertical displacements caused by the deformation of mine shaft.
