Elevator safety supervision method

The invention discloses an elevator safety supervision method which is realized by adopting an elevator safety monitoring system and comprises the following steps: a hardware sensing layer of the elevator safety monitoring system acquires operation data of an elevator in real time through a sensor and a camera; the camera transmits frame data into a machine vision main board of the elevator safety monitoring system; the terminal APP collects face recognition information, positioning information and maintenance related information of maintenance personnel; data sensed by the hardware sensing layer and data collected by the terminal APP are transmitted into a data layer of the elevator safety monitoring system for data classification; the classified data are transmitted to a supporting layer of the elevator safety monitoring system for further processing; the supporting layer transmits the data subjected to preliminary arrangement to a service layer of the elevator safety monitoring system for service; the data
