The invention provides a positioning, speed-measuring and height-measuring method for maglev trains. The positioning, speed measuring and height measuring method for maglev trains comprises a positioning, speed measuring and height measuring device. The positioning, speed-measuring and height-measuring device comprises triangular rulers, a vehicle-mounted photoelectric sensor group, a motor control panel and a wireless signal transmitting and receiving device, wherein the triangular rulers are arranged along the running route of a train, are uniform in specification, and are arranged on the two sides of a track in parallel, and the wireless signal transmitting and receiving device is used for transmitting detection signals of the vehicle-mounted photoelectric sensor group to the motor control panel. The vehicle-mounted photoelectric sensors are arranged on the lower portion of the train and comprise light spot reflection point type probes and amplifiers, and the positioning, speed measuring and height measuring device achieves positioning, speed measuring and height measuring of the train on the basis of the principle that a vernier caliper improves precision. The method is suitable for positioning and speed measurement of the maglev trains and has the advantages of being high in positioning precision and low in cost, the positioning precision can reach the millimeter level oreven higher, and scheme design can be conducted according to the precision requirement of a system.
