The invention discloses a positioning device and method for a maglev train, and the device comprises a plurality of laser emission sources which are respectively disposed on a track, the position of each laser emission source is corresponding to the position of a long stator segment on a track beam, and each long stator segment is provided with coding information for determining an absolute position; a reflection source which is arranged on the maglev train; a processor which is in communication connection with the reflection source and each laser emission source, and the processor is configured to respond to the reflection source reflection light wave signal and determine the coding information of the long stator segment corresponding to the laser emission source emitting the light wave signal, and calculating the position of the maglev train according to the absolute position determined by the encoding information and the round-trip time of the light wave signal. According to the device, an optical measurement mode is adopted, the device is not affected by the surrounding electromagnetic environment, is less affected by the environment, is high in measurement speed, improves thepositioning precision and reliability, and does not need a wireless transmission medium, thereby effectively reducing the cost investment.

    本发明公开了一种磁悬浮列车的定位装置及方法,定位装置包括:若干个激光发射源,分别设置于轨道上,每一个激光发射源的位置分别与轨道梁上的一个长定子段的位置对应,每一个长定子段分别具有用于确定绝对位置的编码信息;反射源,设置于磁悬浮列车上;处理器,与反射源及每一个激光发射源通信连接,处理器被配置为响应于反射源反射光波信号,确定出发射该光波信号的激光发射源对应的长定子段的编码信息,并且根据编码信息确定出的绝对位置及光波信号的往返时间计算出磁悬浮列车的位置。本发明采用光学测量的方式,不受周围电磁环境,受环境影响较小,测量速度快,提升了定位精度及可靠性,而且无需无线传输介质,从而有效地降低了成本投入。
