Abstract
The invention provides a matching method for dynamic and static inspection data of a track, which comprises the following steps of: intercepting high and low (or track direction) data of dynamic inspection according to a first preset mileage range, and calculating a midpoint vector distance according to chord length defined by the static inspection to obtain training data; selecting high and to-be-matched low (or rail direction) data of static inspection as test data; and calculating a minimum cumulative distance path of the training data and the test data by adopting dynamic time warping to obtain a matching relationship between dynamic and static inspection data. According to the invention, midpoint vector distances are used for unified height (or rail direction) definition; the similarity relation between dynamic and static inspection data is established, then translation, stretching, drifting and bending of waveforms of different inspection systems in amplitude and mileage are overcome through dynamic time warping, accurate matching of the dynamic and static inspection data is achieved, and the method can be used for improving track state evaluation, comprehensive analysis of detection data and the diagnosis effect of track diseases.
Description
technical field [0001] The invention relates to the field of track inspection, in particular to a method for matching track dynamic and static measurement data. Background technique [0002] The combination of the track structure and the randomness and repetition of the train loads it bears lead to uneven changes in the track geometry and position, forming various irregularities in the track, and affecting the safety, stability, comfort, and vehicle safety of the train. and track component life. Therefore, the track needs to be regularly maintained. [0003] The basic process of regular track maintenance mainly includes dynamic inspection data analysis, determination of disease locations, on-site static inspection and confirmation, comprehensive analysis of inspection data, formulation of operation plans, approval of operation plans, reporting of daily skylight operation plans, implementation of operation plans, re-inspection of operation quality and filling in Steps such ...
