摘　　要：在现有的GJ⁃6型轨道检测系统平台基础上添加了曲线正矢的检测算法,提出了一种基于惯性正矢法进行曲线正矢检测的方法。为验证该方法的可靠性,基于某线路轨检车检测数据计算其曲线正矢,并与轨检仪检测结果进行对比。结果表明:本文方法算得的曲线正矢与轨检仪检测结果较为相似,可以反映曲线的圆顺性,检测结果可靠。本文方法仅改变了现有系统的软件部分,便于系统升级,可以丰富轨道检测系统的功能。Based on the existing GJ-6 track detection system platform,a curve versine detection method based on inertial versine method was proposed by adding curve versine detection algorithm.In order to verify the reliability of this method,the curve versine was calculated based on the detection data of a track inspection car,and compared with the detection results of the track inspection instrument.The results show that the curve versine calculated by this method is similar to the test results of the track inspection instrument,which can reflect the roundness of the curve,and the test results are reliable.The method in this paper only changes the software part of the existing system,facilitates the system upgrade,and can enrich the functions of the track detection system.
