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

Abstract

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 data exceeds a threshold range set within a limited time range, the abnormal data is marked as fault data, and an alarm is reported. According to the invention, faults can be judged more accurately under the condition of ensuring timeliness, and the false alarm rate of the monitoring system is reduced.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a smart elevator monitoring system and method based on NB-IOT wireless communication. Background technique [0002] Traditional maintenance mode: The property owner / property reports the elevator failure by telephone → the operation and maintenance personnel notify the maintenance personnel of the project by telephone according to the company structure → the maintenance personnel go to the said location for maintenance after receiving the call. The efficiency of the traditional maintenance mode is low, and it is often impossible to rush to the scene for rescue in time. Although the existing elevator monitoring system can alarm in time, there is a high rate of system false alarms, that is, some faults return to normal at the moment of occurrence, and the normal operation of the elevator is not affected. , However, the maintenance personnel cannot attend work after knowing the rea...

Problems solved by technology

The efficiency of the traditional maintenance mode is low, and it is often impossible to arrive at the scene for rescue in time. Although the existing elevator monitoring system can alarm in time, there is a high rate of system false alarms, that is, some faults return to normal at the moment of occurrence, and the normal operation of the elevator is not affected. , but the maintenance personnel cannot attend work after knowing the real situation, resulting in a great waste of working time and unable to guarantee the quality of maintenance services

[0003] The current problem with the elevator remote monitoring system is the high rate of false alarms, and according to the actual situation, an elevator may have several false alarm data in one day, that is, after some elevator failures, the failure will return to normal at the moment of occurrence, without affecting the elevator The normal operation, but the background received an alarm, did not know that the elevator has returned to normal, and still dispatched to repair, time-consuming and laborious
