Study of Velocity Measurement Error Analysis and Improving Velocity Measurement Accuracy on High-Speed Train

Abstract:

For the problem of a big velocity measurement error,analyzed the velocity measurement error and studied the method of improving velocity measurement accuracy for the velocity measuring system of high-speed train.In this analysis and method, the speed error analysis was carried out based on understand the characteristics of the high-speed train speed sensor, and found that there is a bigger error. Then discussed the influence of large errors of the control system, and then put forward the improved M/T speed measurement method to solve the error problem. Finally, calculated velocity-measuring error for the improved M/T speed measurement method. The results show that the accuracy of speed has improved greatly. The research method can improve the accuracy to meet the requiring of train safety and smooth run.
