高速磁悬浮列车定位测速系统

为实现高速磁浮列车位置和速度检测，提出一个检测方案．该方案通过检测长定子直线同步电机的齿一槽和轨道旁固定位置的绝对位置参考板获取相对位置与绝对位置信号，并利用这2个信号相互校验，消除检测过程中产生的误差．在与上海高速磁浮示范运营线完全相同的长定子上进行的实验结果证明所提方案是可行的．

Location and Speed Detection System for High-Speed Maglev Vehicle

To detect the location and speed of high-speed maglev (magnetically levitated) vehicles, a location and speed detecting scheme was proposed. In this scheme, the tooth-and-slots of the LSM (linear synchronous motor) and the location reference leaves beside the track are detected as the relative and absolute location signals, respectively. These signals are compared each other to eliminate the measuring errors. The experiments on the test bench that contains the same long stator as the LSM used in Shanghai high-speed maglev line show that the proposed scheme is feasible.
