Example Embodiment
[0012] Embodiment: The elevator monitoring method based on the photoelectric sensor of this embodiment includes the following steps:
[0013] 1) Install photoelectric sensors in the elevator.
[0014] 2) Connect the signal output terminal of the photoelectric sensor to the control device of the existing elevator monitoring system.
[0015] 3) The control device collects the signal output by the photoelectric sensor to record the time when the elevator has people entering and exiting. When the photoelectric sensor collects the person entering and exiting signal, the control device sends the control signal to the monitor to improve the brightness of the image displayed on the monitor.
[0016] 4) The memory in the video capture device only stores the video that is recorded in step 3) for the time of entry and exit of people, which is increased by 1 to 3 minutes, and the rest of the video is displayed on the monitor in real time and discarded.
