Abstract

The invention relates to the field of automatic door lubrication, and discloses an online prediction method for lubrication failure of an automatic door system, which includes two parts: model training and online monitoring. The model training includes original data collection, data preprocessing, data segmentation, feature extraction, and feature regression. Synthesis, feature selection, establishment of lubrication decline trend model and definition of failure threshold; online monitoring includes data collection, data preprocessing, data segmentation, feature extraction, feature normalization, calculation of health and lubrication failure alarm. The present invention calculates the health index of lubrication decline in real time through real-time online monitoring process data and a complete modeling process, realizes online monitoring and early warning, and then changes the operation and maintenance strategy, from post-maintenance or over-maintenance to pre-prediction and depending on the situation maintain.

Description

technical field [0001] The invention relates to the field of automatic door lubrication, in particular to an online prediction method for lubrication failure of an automatic door system. Background technique [0002] Rail vehicle automatic door system, as an important component of rail transit equipment, due to its high frequency of use and diverse use scenarios, its performance stability and reliability are directly related to the safety of the vehicle, and the current operation and maintenance methods Mainly professional maintenance personnel provide spot checks and fixed repairs and equipment failure-driven after-the-fact maintenance (Fail-and-Fix). However, the traditional operation and maintenance method not only causes waste of operating costs, but also has invisible safety hazards . [0003] Rail vehicle doors generally use electric double-open plug doors. When the door is fully closed, the door leaf is flush with the outer surface of the vehicle. When opening the d...
