Embodiment Construction
[0020] specific implementation plan
[0021] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0022] The invention proposes to divide the long motion segment into smaller segments according to the motion pattern, and then use random selection and condition constraints to make the operating conditions constructed have typical characteristics and the length of the operating conditions can be controlled. The present invention constructs the flow process of train typical working condition as follows figure 1 As shown, first collect train data according to the construction requirements of the working conditions; secondly, eliminate unreasonable data; then preprocess the remaining valid data, including interpolation, resampling to supplement missing data and adjust sampling frequency, and filter to eliminate noise; Then, each motion segment is divided into short segments according to the motion pattern; finally...
