The invention discloses a magnetically-levitated-train speed detecting method based on sleeper detection. The magnetically-levitated-train speed detecting method includes the steps of 1, sequentially arranging two or more sleeper detection sensors on a train at assigned intervals, and after the train is started to run, proceeding to execute the step 2; 2, obtaining the current running acceleration of the train, and calculating the current speed of the train according to the obtained acceleration; 3, judging whether the current speed of the train is in a preset low speed zone or not, if the current speed of the train is in the preset low speed zone, returning to execute the step 2 to carry out speed compensation on the low speed zone, and if the current speed of the train is not in the preset low speed zone, proceeding to execute the step 4; and 4, receiving detection signals transmitted by the sleeper detection sensors in real time, calculating the current speed of the train according to the detection signals, and returning to execute the step 3 till the train stops running. According to the magnetically-levitated-train speed detecting method, the speed of the magnetically-levitated train is detected based on sleeper detection, and meanwhile compensation can be carried out on the speed of the low speed zone; and the magnetically-levitated-train speed detecting method has the beneficial effects that an achieving method is simple, and the detection accuracy in a non-low-speed zone and the accuracy in the low speed zone are both high.
