摘要
以某高铁线路特定区间的接触网为研究对象,对该接触网服役期间的动静态参数进行特征提取,通过采用连续隐马尔科夫模型(CHMM)实现了对接触网当前状态的识别及性能退化分析,经实例分析验证了结果的正确性以及该方法用于接触网性能退化分析的可行性。
With one certain section of a high speed railway line as the target of researches,carry out the feature extraction of dynamic parameters during servicing period of this overhead contact line,realize the identification of its current status and analysis of its degradation by means of CHMM model,verify the correctness of results through analyzing the actual examples,and verify the feasibility of method for analyzing the degradation of performance of overhead contact line.
