摘要
介绍基于脉冲速度传感器和加速度计的测速测距系统。分析了列车空转打滑过程,根据加速度和速度的变化,将空转打滑划分为加速度空转打滑和速度空转打滑;对2种空转打滑的检测算法以及相应的补偿算法进行了详细阐述;运用SCADE进行仿真。结果表明,该算法对空转打滑造成的测量误差有很好的补偿作用。
Velocity and distance measurement system based on pulse speed sensor and accelerometer was introduced. Process of train slide or slip was analyzed, and according to the change of acceleration and velocity, the slide or slip was divided into acceleration slide or slip and velocity slide or slip. The two detection algorithms and the corresponding compensation algorithms were described in detail; SCADE was used for simulation, and the results showed that the algorithm had a good compensation effect on the measurement error caused by slide or slip.
