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.
