The invention relates to the technical field of positioning of track type transportation equipment, and particularly discloses a positioning method and system for track type transportation equipment.The method comprises the steps that data of a first position of a vehicle body after moving are obtained through an encoder, and permanent magnets along the way of a track are induced through a magnetic inductor to obtain a magnetic mutation signal and know the current position; an RFID card reader reads RFID electronic tags when passing through positioning pieces so as to confirm how many permanent magnets are passed at the current position to obtain data of a second position where the vehicle body is located; and a controller corrects the value of the data of the first position according tothe data of the second position. The system comprises the track and the vehicle body running along the track, and a plurality of RFID electronic tags and permanent magnets are arranged along the track; and the controller, the encoder, the RFID card reader and the magnetic inductor are arranged on the vehicle body. The positioning precision, reliability and maintainability of the track type transportation equipment are improved.

    本发明涉及轨道型运输设备定位的技术领域,具体公开涉及一种轨道型运输设备的定位方法及其系统,其方法包括步骤:通过编码器获取车体经过移动的第一位置数据,磁感应器感应轨道沿途的永磁体得到磁突变信号,得知当前所在位置,RFID读卡器经过定位件时读取RFID电子标签、从而确认当前所在位置经过多少个永磁体,得到车体所在的第二位置数据;控制器根据第二位置数据来对第一位置数据的值进行校正;其系统包括轨道及沿轨道运行的车体,轨道沿途布设多个RFID电子标签和永磁体;车体上设置有:控制器、编码器、RFID读卡器、及磁感应器。改善了轨道型运输设备定位的精度、可靠性及易维护性。
