The invention discloses an electric passenger car track detection method, which comprises the following steps of: starting initialization after a track detection host is electrified, entering a waiting state after completion, reading a tag ID, judging the tag ID, starting detection if the tag ID is started, and continuing to detect the tag ID if the tag ID is not started. The track detection host obtains the transverse/vertical acceleration of a vehicle through the triaxial accelerometer, obtains a line radio frequency tag signal through the radio frequency tag reader, and obtains and calculates track information through the inertial navigation device. And the synchronous controller outputs mileage information to the rail detection host after acquiring a signal of the speed sensor, and triggers the laser triangulation assembly to acquire steel rail profile data. The rail inspection host obtains the transverse/vertical acceleration, the track, the mileage and the steel rail profile information of the vehicle, and solves the geometric parameter data of the rail. The technical problems that an existing rail detection operation mode is low in operation efficiency, real-time online detection cannot be achieved, and detection line data cannot truly reflect line dynamic parameters in the running state of the electric passenger car can be solved.
本申请公开了一种电客车轨检方法,轨检主机上电后开始初始化,完成后进入等待状态,读取标签ID后,对标签ID进行判断,如果是开始标签ID,则开始检测,如果不是,则继续检测标签ID。轨检主机通过三轴加速度计获取车辆横向/垂向加速度,通过射频标签阅读器获取线路射频标签信号,通过惯导装置获取并推算航迹信息。同步控制器获取速度传感器信号后向轨检主机输出里程信息,并触发激光三角测量组件获取钢轨廓形数据。轨检主机获取车辆的横向/垂向加速度、航迹、里程及钢轨廓形信息,并解算出轨道几何参数数据。本申请能解决现有轨检作业方式作业效率低,无法实时在线检测,检测线路数据不能真实反映电客车运行状态线路动态参数的技术问题。
