If the number of people searched by all the high-definition infrared cameras within 5 minutes is not If there are more than 100 people, the central processor will send the counted data to the LED switch processing module, and the LED switch processing module will start a countdown for 1 minute and shut down. During this 1 minute, the camera is still searching for people within the visible range. If there are 100 people, the power module will exit the shutdown state. Otherwise, the large screen will shut down after 1 minute. Such power management can maximize the utilization rate of the outdoor LED screen, especially in non-rest days and late nights when the flow of people is scarce. Moreover, the power consumption of outdoor LED screens is tens of thousands of watts to hundreds of thousands of watts. Such power control not only reduces the work intensity of LED screen managers, but also optimizes the use efficiency of outdoor LED screens, effectively controlling and reducing energy consumption.
