摘　　要：列车不间断地运行会使铁路轨道发生变形或损坏,因此必须加强对铁路轨道几何参数的检查。本文首先分析了轨道几何参数的检测原理,然后针对静态轨道检查设备,利用全球导航卫星系统定位技术布设GNSS控制网,对轨道几何状态检查系统进行了硬件设计和软件设计,最后通过上位机数据处理可得到高精度的轨道内部几何参数和外部几何参数。The uninterrupted operation of trains can cause deformation or damage to railway tracks,so it is necessary to strengthen the inspection of railway track geometric parameters.This paper first analyzes the detection principle of orbital geometric parameters.Then,for static orbital inspection equipment,a GNSS control network is deployed using global navigation satellite system positioning technology to design the hardware and software of the orbital geometric state inspection system.Finally,high-precision internal and external orbital geometric parameters can be obtained through data processing on the upper computer.
