摘　　要：铁路轨道是铁路运输的重要设备,其几何状态参数检测在铁路的日常维护和建设中非常重要。我国传统的工务维修通常采用轨检仪与全站仪等光学设备共同配合检测,该方法虽然能测量轨道的几何参数,但受温度、光照、风雨等环境的影响大,且操作复杂、成本高、作业速度慢。为此,本文提出一种利用GNSS技术、RTK技术、4G无线通信技术,采用“相对测量”与“绝对测量”相结合的检测方法,构建基于GNSS的轨道几何状态检测系统,实时检测轨道几何状态参数。Railway track is an important equipment in railway transportation,and the geometric state parameter detection of railway track is very important in the daily maintenance and construction of railways.Traditional track maintenance in China usually uses optical equipment such as a track inspection instrument and a total station to cooperate with detection.Although this method can measure the geometric parameters of the track,it is greatly affected by temperature,light,wind and rain,and other environments,resulting in complex operations,high costs,and slow operation speed.Therefore,this paper proposes a detection method that utilizes GNSS technology,RTK technology,4G wireless communication technology,and combines"relative measurement"and"absolute measurement"to construct a GNSS based track geometry state detection system,which can detect track geometry state parameters in real-time.
