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 application discloses a method and a device for predicting the running state of an elevator door system. According to the collected operation data of the elevator door system, the operation data matrix of the elevator door system is constructed. The operation data includes the data of the controller LAN bus and the vibration data of the elevator door system; the feature extraction is performed on the operation data matrix to obtain the feature vector; The health assessment algorithm performs health assessment on the eigenvectors to obtain the health value of the elevator door system operation; according to the operating characteristic data and the health value, predicts the health value of the future moment, and obtains the operation of the elevator door system in the predicted time period Performance degradation information. The method realizes the accurate prediction of the performance degradation trend of the elevator door system, and improves the reliability of the elevator door system operation.
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...
