Abstract

The invention relates to an elevator fault early-warning method based on the Internet of Things technology and a coupled graph neural network. The elevator fault early-warning method based on the Internet of Things technology and the coupled graph neural network comprises the following steps: a, acquiring data in an elevator car in real time, and transmitting the collected data to a cloud; b, preprocessing the data, and carrying out feature extraction; and c, utilizing a pre-trained coupled graph neural network model for analyzing the data acquired in real time at the cloud, and carrying out early-warning on elevator faults in advance. According to the invention, early-warning for the elevator faults is realized in advance through the coupled neural network model, and therefore the elevator fault early-warning method has higher accuracy and precision compared with a traditional mode under the conditions that data are unbalanced and fault data are few.

Description

technical field [0001] The invention relates to an elevator fault early warning method based on Internet of Things technology and a coupling graph neural network. Background technique [0002] With the increase of modern high-rise buildings, elevators have become an important means of transportation. As the service life of the elevator increases, more and more elevator failures occur. Due to many elevator brands and various types of failures, it is difficult to predict elevator failures in advance. [0003] In the prior art, the establishment of statistical analysis and regular maintenance is usually used to realize the early intervention of the elevator failure. With the development of big data, machine learning and artificial intelligence technology, some technologies have begun to combine big data and use deep neural networks to provide early warning of elevator failures. Common models mainly include: tree model (Xgboost, GBDT, etc.), support vector product, LSTM, etc....
