摘　　要：对地铁限界及轨道几何状态进行检测是地铁运营维护的重要工作,采用人工检测既费时又费力,运用大型轨检车的费用太高。为了便携快捷地检测地铁限界及轨道几何状态,基于多传感器集成开发一种便携检测装置,进行检测应用研究。通过将激光扫描仪、轨距传感器、里程计和倾角仪等传感器集成到轨检小车上,设计配套的软件系统,构造了限界检测、轨距计算、超高计算、坐标系转换和里程计标定等板块。应用该便携装置对长沙地铁三号线侯家塘站至四方坪站进行检测,分析和验证了检测结果,检测装置最终实现了超限报警、图形及超限数据自动录入、轨枕自动识别及轨道几何尺寸数据自动采集等多项功能。The detection of metro gauge and track geometry is an important work of metro operation and maintenance.Manual inspection is time-consuming and laborious,and the cost of using large-scale rail inspection vehicle is too high.Therefore,in order to detect the subway gauge and track geometry state conveniently and quickly,a portable detection device based on multi-sensor integration was developed,and the detection application research was carried out.The laser scanner,gauge sensor,odometer and inclinometer were integrated into the track inspection trolley,and the software system was designed.The function blocks of gauge detection,track gauge calculation,super elevation calculation,coordinate system conversion and odometer calibration were realized.The portable device was applied to detect Houjiatang station to Sifangping station of Changsha Metro Line 3,and the detection results were analyzed and verified.Finally,the detection device realizes the functions of gauge intrusion alarm,automatic input of graphics and gauge intrusion data,automatic identification of sleepers and automatic collection of track geometry data.
