本文详细介绍一种用于大面积煤堆体积自动检测系统。由扫描车、激光器和线阵CCD摄像机组成的扫描探测系统,把煤堆分成若干小面积,并测出每个小面积的高度,再进行积分求出煤堆总体积。采用单片机系统实现扫描控制、数据采集和数据处理。该系统具有打印输出、数字显示和绘图功能,测量误差约为1％。 This article describes in detail a large area for coal pile volume automatic detection system. A scanning detection system composed of scan carts, lasers and linear CCD cameras divides the coal piles into small areas and measures the height of each small area. The total volume of the coal piles is then calculated by integration. Using SCM system to achieve scan control, data acquisition and data processing. The system has a print output, digital display and drawing capabilities, measurement error of about 1%.
