Intelligent elevator monitoring system and method based on NB-IOT wireless communication

An intelligent elevator monitoring system based on NB-IOT wireless communication comprises an elevator state monitoring device, an NBIOT wireless communication module, an unvarnished transmission cloud server and a server. The elevator state monitoring device is connected with the elevator control cabinet and used for collecting elevator running state information and transmitting the abnormal elevator running state information to the transparent transmission cloud server through the NB-IOT wireless communication module, and the transparent transmission cloud server summarizes received serial port data of all elevators into original data streams and then sends the original data streams to the server. The server carries out timing processing on the summarized abnormal elevator data, and if the abnormal data does not reach the occurrence frequency standard within the limited time range, the abnormal data is marked as early warning information; and if the number of times of continuous reporting of the abnormal da
