System and method for detecting elevator maintenance behavior in elevator hoistway

A system for detecting elevator maintenance behaviors of a maintainer in an elevator hoistway, which 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 coupled to the receiving component, which comprises:
• a memory that stores CSI image recognition models constructed corresponding to one or more predefined elevator maintenance behaviors and a corresponding computer program executable on a processor;
• and
• the processor, which is 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 of the maintainer in the elevator hoistway.
