摘要
针对断面监视系统的一般工作原理,提出了一种断面监视系统性能试验方法。该方法通过建立机身和巷道基准来测量截割头表面特征点的空间位置,当截割头在断面监视系统引导下完成整个断面扫描后,将获得的一系列特征点空间轨迹按照机身和巷道基准投影到定义断面轮廓的平面上,从而形成实际断面轮廓;最后按照角度偏差、位置偏差和形状偏差三类指标对实际断面轮廓和设计断面轮廓进行比较,完成对断面监视系统的性能评价。试验结果验证了该方法的有效性和正确性。
The paper presented a performance testing method of section monitoring system according to general working principle of section monitoring system.The method measures spatial position of feature point on cutting header by setting references of roadheader and roadway,and projected spatial track of a series feature points obtained on the plane where section outline was defined according to the references of roadheader and roadway when cutting header completes section scanning under guiding to section monitoring system,so as to form a real section outline.Finally,the method compared the real section outline with the defined one according to indexes of angle error,position error and shape error to complete performance evaluation of section monitoring system.The experimental result showed that the method is effective and accurate.
