摘要
中低速磁浮列车因其特性,无法使用轮轴式传感器测量车轮运动状态,也无法像高速磁浮测速那样通过检测轨面上分布规律的参照物来计算列车的速度与位置。提出了一种基于中低速磁浮钢轨枕的高精度测速定位方法,使用加速度计和涡流传感器检测列车运动状态,再与雷达的信息进行比较判断,共同计算出列车的速度和位置。通过在长沙中低速磁浮线路上的试验测试,证实这种测速方法的精确度和实时性能够满足需求。
Due to its characteristics,the medium and low speed maglev train can neither use the axle type sensor to measure the wheel/axle movement,nor use the regularly distributed reference substance on the rail to calculate the movement of train like the high-speed maglev train.In this paper,a high precision technology to detect the speed and position of the train is put forward,which is based on the steel sleepers used for the medium and low speed maglev line.By using accelerometer and eddy current sensor,the train movement is detected and then compared with radar information,the speed and position of train is thus calculated.Through tests on the middle and low speed maglev lines in Changsha City,the accuracy and real-time performance of the speed measurement is verified.
