Problems solved by technology

[0002] A video monitoring system is usually installed in the elevator for abnormal monitoring purposes. It has a direct display monitor, which can be viewed in real time by security personnel, and the video recording method is used to keep a certain amount of monitoring video for future reference. During the real-time viewing process, due to the single screen, It is very easy to fatigue, and the video not only takes up a large storage space, but also requires a lot of work and time-consuming when reviewing manual screening. There is an urgent need for a kind of information that can intelligently remind security personnel to pay attention to, and intelligently compress the video. Monitoring method of useful information

Embodiment

[0012] Embodiment: the elevator monitoring method based on the photoelectric sensor of the present embodiment comprises the following steps:

[0013] 1) Install a photoelectric sensor in the elevator.

[0014] 2) Connect the signal output end 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 people enter and leave the elevator. When the photoelectric sensor collects the signal of people entering and leaving, the control device sends the control signal to the monitor to increase the brightness of the image displayed on the monitor.

[0016] 4) The memory in the video acquisition device only stores the video recorded in step 3) with 1 to 3 minutes added forward and backward based on the time when people entered and exited, and the rest of the video is displayed on the monitor in real time and then discarded.
