In order to improve the operation safety and efficiency of the maglev train, multi-sensor information fu?sion technology is adopted in low-speed maglev trains speed positioning. The relative positioning is realized by the radar and cross induction coil, and the absolute positioning is conducted by the balise. Particle filter algorithm is used to analyze the low-speed maglev train speed positioning accuracy and reliability, and MATLAB simulation is then adopted to verify the results. It maintains that the fusion structure and fusion algorithm effectively improve the positioning accuracy of the train by exploring the error effect caused by random noise.
