摘要: 针对矿井井壁变形引起的径向位移测量问题,提出了一种基于CCD的垂线坐标仪的设计方案,给出了垂线坐标仪的结构及其在井壁变形监测系统中的布置,详细介绍了垂线坐标仪的软、硬件设计。该垂线坐标仪利用CCD采集光信号并将其转换为视频信号,采用LPC932对采集的视频信号进行二值化处理及计数,并将处理结果发送至地面计算机进行分析,从而得到矿井井壁变形引起的径向位移量。测试结果验证了该垂线坐标仪的稳定性和精确性。Abstract: In order to solve the problem of measuring horizontal displacement caused by deformation of shaft wall of mine, a design scheme of vertical plumb coordinatograph based on CCD was proposed, the structure of the vertical plumb coordinatograph and its distribution in monitoring system for deformation of shaft wall were given, and software and hardware design of the vertical plumb coordinatograph were introduced in details. The vertical plumb coordinatograph collects light signals and convert the light signals to video signals by use of CCD, does binary processing and counting of the collected video signals by use of LPC932, and transmits the processed results to computer on the ground for analysis, so that to get horizontal displacement caused by deformation of shaft wall of mine. The testing result showed the stability and accuracy of the vertical plumb coordinatograph.
