Example Embodiment
[0046] The present invention will be further described below in conjunction with the embodiments shown in the drawings.
[0047] A turnout abnormal early warning and fault diagnosis method, which is based on a large number of turnout monitoring curves, through comprehensive analysis through segmentation, standard action current curve extraction, feature analysis and other means to realize abnormal early warning and fault diagnosis. The method includes the following steps:
[0048] (1) For a particular turnout (ie turnout to be tested), select its standard operating current curve based on its historical data and obtain historical data statistical characteristics. The historical data statistical characteristics include the normal value range of key features, mainly including the operating current Normal range
[0049] (2) Use the clustering algorithm to segment the current curve of the action to be measured. If it cannot be segmented correctly, it is a fault and go to step (3), otherw...
