摘要
简要介绍了地铁轨检中轨检小车以及捷联惯导的作业原理以及数据处理方法,将轨检小车测量值与组合导航所算得的轨道不平顺性进行对比分析,表明了经惯导解算所得的轨道不平顺参数与轨检小车测量结果比较符合,论证了捷联惯导在地铁轨检中的可行性,并为后续实验提供参考。
This paper briefly introduces the operation principle of track inspection car and the strapdown inertial navigation and data processing method in track inspection.Through comparing and analyzing the measurement by track inspection car and the calaulated results by integrated navigation,it shows that the results obtained by integrated algorithm and that of the car measurement confrom with each other.It verifies the feasibility of the strapdown inertial navigation in subway detection.
