摘要：
In this paper, for the non-contact speed measurement technology of maglev train, the speed measurement accuracy needs to be improved, and the relative positioning error is large. So the MEMS-IMU inertial measurement unit is introduced to compensate the speed of the original speed measurement system, and the error based on the MEMS-IMU speed measurement is performed analysis. Based on this, an error correction method based on wavelet threshold optimization and an optimized speed measurement algorithm are proposed to improve the speed measurement performance.
