Intelligent control system of LED (light-emitting diode) outdoor screen and control method

Abstract

The invention discloses an intelligent control system of an LED (light-emitting diode) outdoor screen. The system comprises a photosensing device and a camera, wherein the LED outdoor screen is connected with an LED brightness processing module and an LED switch processing module; the photosensing device and the camera are connected with a single central processor; the central processor comprisesan information acquisition module and an information publishing module that are connected with an internal local area network; and the central processor is further directly connected with the LED brightness processing module and the LED switch processing module, can process data collected by the photosensing device and the camera and transmits the collected data to the brightness processing moduleand the switch control processing module for automatic adjustment and control of an analog value and power switch-on/off of the LED screen. After the system adopts the structure, an ornamental valueand stability of the LED outdoor screen are effectively improved; the energy consumption is greatly reduced; the service life of the LED screen is prolonged at the same time; more convenient management is provided for an LED screen manager; an audience obtains more aesthetic frame; and the management cost and operating cost are greatly lowered.

Description

technical field [0001] The invention relates to an intelligent control technology for an outdoor LED screen, in particular to an intelligent control system and a control method for an outdoor LED screen. Background technique [0002] With the development of social economy, LED outdoor display screens will be used in advertising, sports, transportation, performances, leasing, wall demonstrations and other occasions. The application of LED large outdoor display screens is becoming more and more extensive, especially as an advertising carrier. It can be seen everywhere on high-rise buildings in the city. The existing LED outdoor display screens require someone to turn on and off regularly every day. The analog values ​​of the display screen (brightness, color saturation, contrast, color temperature) can only be set in advance; when the ambient light has The difference between light and dark will inevitably affect the viewing, stability and service life of the LED screen.
