The invention relates to the elevator control field and the field of the Internet of Things, and provides an intelligent prediction, diagnosis and maintenance system for elevator faults on the basis of the Internet of Things. The intelligent prediction, diagnosis and maintenance system can effectively shorten the time of elevator halt caused by the elevator faults, improve the reliability of elevator running and the elevator maintenance efficiency and guarantee the personal safety and the property safety. According to the technical scheme of an intelligent prediction, diagnosis and maintenance method for the elevator faults on the basis of the Internet of Things, a data acquisition module collects elevator data in real time and transmits the collected data to a server through WIFI or the 4G wireless communication technology, the data are analyzed on the server side through the big data technology, and therefore the elevator faults which are possibly to occur can be predicted; if the elevator faults occur, a fault diagnosis system on the server side can be used for analyzing the faults, then the positions and the reasons of the faults can be provided, and then an intelligent maintenance system on the server side provides solutions to the faults. The intelligent prediction, diagnosis and maintenance method is mainly applied to the elevator control occasion.
