| 摘 要： | 设计了一种轮轴速度传感器和雷达速度传感器相结合的列车测速测距系统。该系统针对测速轮对空转/滑行造成的轮轴速度传感器测速测距误差问题,建立了空转/滑行检测判断模型和空转/滑行过程中的列车速度和走行距离误差校正模型。在实验室环境下搭建了该测速测距仿真系统,通过仿真试验验证了模型的有效性。该系统提高了列车测速测距的精度和可靠性。

| Abstract: | A train speed and distance measurement system based on tachometer and Doppler radar is designed.Since the wheel slip/slide will cause errors of tachometer in speed and distance measurement,a slip/slide detection and error correction model based on train speed and distance measurement system is established.The simulation system of this model is built in laboratory environment and the simulation results have verified the validity of the model,which could improve the independent positioning capability of train position system. |
