SYSTÈME ET PROCÉDÉ DE DÉTECTION COMPORTEMENTS DE MAINTENANCE D'ASCENSEUR DANS UNE CAGE D'ASCENSEUR

摘要

The present disclosure relates to system and method for detecting elevator maintenance behaviors in an elevator hoistway. The system of the invention comprises: an emitting component for emitting wireless signals including channel state information (CSI) into the elevator hoistway; a receiving component for receiving the CSI from the elevator hoistway; and a maintenance behavior detecting device, which comprises: a memory that stores CIS image recognition models constructed corresponding to the predefined elevator maintenance behaviors and a corresponding computer program executable on a processor, and the processor configured to be able to execute the computer program to implement the following operations: processing data of the received CSI to obtain a CSI image corresponding to the elevator maintenance behavior detected, and inputting the CSI image to the CSI image recognition model for analysis and processing so as to detect the elevator maintenance behavior. The system and method of the present invention can identify the elevator maintenance behaviors in the elevator hoistway with a high accuracy, so they are especially suitable for the elevator hoistway environment
