Elevator equipment fault prediction method based on depth learning

Abstract

The invention relates to an elevator equipment fault prediction method based on depth learning, belonging to the technical field of elevator fault prediction. The technical problem to be solved is toprovide a timely and accurate method to predict the type and time of elevator failure. In order to solve the technical problems, the concrete steps of the invention are summarized as follows: firstly,the elevator fault record information is collected and a real-time elevator fault information database is established; then the elevator fault information is processed into event sequence and time sequence; the event sequence and time sequence are used as the input data of double LSTM respectively, and the output embedding of the two sequences is obtained by iterative training of the loop neuralnetwork; then, the background knowledge and the nonlinear representation of the historical influence of the intensity function are obtained through joint player combined with two output embedding; finally, according to the characterization results of the strength function, the fault type and time of elevator are predicted. The invention can assist elevator maintenance personnel to take relevant preventive measures as early as possible to avoid occurrence of failure events.

Description

technical field [0001] The invention discloses a method for predicting faults of elevator equipment based on deep learning, and belongs to the technical field of fault prediction of elevators. Background technique [0002] With the continuous increase of high-rise buildings, the quality of elevators has attracted people's attention. Elevators that fail to stop, run poorly or even have accidents have affected people's daily life. To reduce the failure rate of elevators, the method of timely and accurate detection and troubleshooting needs further research. The current elevator fault diagnosis and detection methods mostly combine the elevator structure and principle, and propose detection methods for the elevator's mechanical system, electrical control system and safety protection system, but this requires a lot of analysis time. Contents of the invention [0003] The present invention overcomes the deficiencies existing in the prior art, and the technical problem to be so...
