The invention discloses a speed measuring and positioning method of a maglev train and a related assembly, and relates to the field of maglev train control. When the train speed of the maglev train exceeds a preset speed upper limit value, a long stator synchronous linear motor is directly used as a power source for the running of the maglev train; the speed of the maglev train can be determined according to the motor speed of the long-stator synchronous linear motor, that is, when the maglev train runs at a high speed, a ground control center does not need to communicate with a positioning test system arranged on the maglev train through a wireless transmission device; the running state of the maglev train can be directly determined by detecting the long-stator synchronous linear motor, transmission delay is avoided, meanwhile, position information and train speed are obtained through first coding information sent by the wireless transmission device, the two sets of measurement processes are mutually independent, and the measurement accuracy is high. The reliability of the speed measurement positioning result and the control stability of controlling the traction state of the maglev train are improved.
本发明公开了一种磁浮列车的测速定位方法及相关组件,涉及磁浮列车控制领域,当磁浮列车的列车速度超过预设的速度上限值时,由于长定子同步直线电动机直接作为磁浮列车行驶的动力源,可以根据长定子同步直线电动机的电机速度确定磁浮列车的速度,即在磁浮列车高速运行时,地面控制中心无需通过无线传输装置与磁浮列车上设置的定位测试系统进行通信,可以通过对长定子同步直线电动机的检测直接确定磁浮列车的运行状态,无传输延时,同时也通过无线传输装置发送的第一编码信息进行位置信息和列车速度的获取,两套测量流程互相独立,提高了测速定位结果的可靠性和对磁浮列车的牵引状态进行控制的控制稳定性。
