论文摘要
本文档介绍了用于计算轨道几何不规则性的理论，该轨道几何测量系统（TGMS）将安装在铁路车辆中。 TGMS包括一台用于数据采集和过程的计算机，一组传感器，包括惯性测量单元（IMU，3D陀螺仪和3D加速度计），两个摄像机和一个编码器。提出的系统的主要特征是：1。它能够使用非接触技术测量轨道对齐，垂直轮廓，跨层，尺度，扭曲和轨道头轮廓。 2。它可以安装在线路车辆中。它是紧凑的，低成本。只要设备在车辆移动时会看到轨头头，则可以将其安装在车辆的任何物体中：在轮子级别，高于初级悬架（4号框架）或高于次级悬架（车身车身）。
This document describes the theory used for the calculation of track geometric irregularities on a Track Geometry Measuring System (TGMS) to be installed in railway vehicles. The TGMS includes a computer for data acquisition and process, a set of sensors including an inertial measuring unit (IMU, 3D gyroscope and 3D accelerometer), two video cameras and an encoder. The main features of the proposed system are: 1. It is capable to measure track alignment, vertical profile, cross-level, gauge, twist and rail-head profile using non-contact technology. 2. It can be installed in line railway vehicles. It is compact and low cost. Provided that the equipment sees the rail heads when the vehicle is moving, it can be installed in any body of the vehicle: at the wheelsets level, above primary suspension (bogie frame) or above the secondary suspension (car body).
