Problems solved by technology
[0004] However, the use of Bayesian network modeling requires the accumulation of rich prior knowledge, high requirements for industry experience and historical data, resulting in uncertainty in the accuracy of the modeling, and the above-mentioned elevator fault health diagnosis method is only based on the elevator The failure probability analysis of the data transmitted by the CAN bus cannot predict the performance degradation trend of the elevator door system, and the analysis data is not comprehensive and targeted, resulting in inaccurate prediction of the performance degradation trend of the elevator door system

The invention discloses an elevator door system running state prediction method and device. According to the collected running data of the elevator door system, a running data matrix of the elevator door system is constructed, and the running data comprise data of a controller local area network bus of the elevator door system and vibration data; feature extraction is carried out on the running data matrix to obtain a feature vector; health assessment is carried out on the feature vector by adopting a health assessment algorithm to obtain a health value of running of the elevator door system;and according to the running characteristic data and the health value, the health value at the future moment is predicted to obtain the running performance degradation information of the elevator doorsystem in the prediction time period. According to the method, the performance degradation trend of the elevator door system is accurately predicted, and the running reliability of the elevator doorsystem is improved.
Description
technical field [0001] The present application relates to the technical field of elevator performance maintenance, in particular to a method and device for predicting the operating state of an elevator door system. Background technique [0002] As China's urbanization continues to accelerate and high-rise buildings are increasing year by year, elevators are increasingly becoming a convenient vertical transportation tool for people to travel. However, as an important member of the characteristic equipment family, its safety hazards are increasingly concerned by everyone, especially the door system of the elevator. Once a failure occurs, it will affect the normal operation of the whole machine, and even cause casualties to passengers. According to statistics, more than 80% of elevator failures and more than 70% of elevator accidents are caused by problems with the door system. It can be seen that it is very important to monitor the condition of the elevator door system. [0...
