The invention discloses a maglev train, a speed measuring and positioning method and a system thereof, a track and a metal tooth groove plate, and relates to the technical field of maglev trains. Different metal tooth groove plates are arranged on the track, the track can adapt to sleepers, installation is convenient, cost is low, at least one sensor is arranged on the vehicle body, redundant configuration is achieved, system reliability is improved, the distance between the fourth coil and the first coil in the track direction is 2.5 times of the third width, the output phase difference of the fourth coil and the first coil is 90 degrees. The direction judgment is carried out. According to the speed measuring and positioning method, periodic on-off signals are output to form square waves when the sensor passes through the metal tooth groove plate, and the absolute position of the train and the speed of the train can be obtained. The speed measuring and positioning method is free of contact and mechanical abrasion, is less affected by weather, and can meet the requirement for accurate benchmarking of automatic driving of the train.
