基于CP Ⅲ的轨道线路坐标解析策略研究及应用

Research and Application of Coordinate Analysis for Track Line Based on CP Ⅲ

在铁路运营维护过程中,目前普遍采用的维护方式为建立有碴铁路固定网系统,该方式除测量CPⅢ的坐标外,还需由大量人力资源来测量线路坐标。以CPⅢ为基准提出一种坐标解析策略来替代建网施工中线路坐标的测量,并经过理论和实测试验论证算法的可行性。结果表明,应用该策略进行测量不仅可以减少人力物力及时间成本,还可以大幅提高作业精度。

In the process of railway operation and maintenance, the establishment of ballast-rail fixed network system was commonly used. This method needed enormous human labors to measure CPⅢ coordinates and railway lines coordinates. Based CP Ⅲ coordinates, a new coordinate resolution strategy was proposed to calculate railway lines coordinate and was verified by tests. The results show that using this method can not only reduce time cost, manpower and material resources, but also substantially improve measurement accuracy.
