The invention discloses a maglev train speed measurement method and system based on sleeper detection. The method comprises the steps that six paths of sensors are arranged below a maglev train body at certain intervals; during normal work, time differences of rising edges of six sensor signals are sampled, the average value is calculated, and the actual running speed of the train is calculated according to the fact that the speed is equal to the distance divided by the time; respectively taking three adjacent sensors as a group, and calculating four groups of speed values; when the sensor breaks down or pulse signals are lost occasionally, the fault is recognized according to different fault working conditions of the sensor, and a reliable speed value is calculated; and according to the collected sensor pulse signals, sensor faults are identified, and alarm signals are sent. The system is used for implementing the method. The device has the advantages of simple principle, convenience in installation, wide application range, high test precision and the like.
