Intelligent control system and control method

Abstract

The invention discloses an outdoor LED screen intelligent control system and a control method. The system comprises an LED screen, a plurality of photosensitive components arranged at the periphery ofthe LED screen and used for acquiring the illuminance of natural light, and a control system used for controlling the LED screen, the control system comprises a central processor and an LED brightness processing module connected with the central processor, the photosensitive components are connected with the central processor and can transmit acquired information to the central processor, and thecentral processor is connected with the LED screen through the LED brightness processing module and can adjust the brightness of the LED screen through the LED brightness processing module accordingto the obtained illuminance of natural light. The control system and the control method are advantageous in that the outdoor LED screen can achieve the optimal picture quality in practical usage, theornamental value and the stability of the outdoor LED screen are improved, the energy consumption is greatly reduced, the service lifetime of the LED screen is prolonged, a more convenient managementmode is provided for managers, more beautiful frames are provided for audiences, and the management cost and the operation cost of the large LED screen are greatly reduced.

Description

technical field [0001] The invention relates to an intelligent control technology for an outdoor LED large 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. In order to save energy consumption, the existing outdoor LED display requires someone to turn on and off the machine regularly every day, and the brightness of the display can only be set in advance. The display is always on during the entire information display process. To maintain the same brightness, the existing LED outdoor display has the following defects: [0003...

AI Technical Summary

Problems solved by technology

[0003] 1. Timed switch on and off every day, although it can save power consumption when no one is watching at night, but it consumes high labor costs, resulting in a waste of labor costs;

[0004] 2. The entire display process maintains a unique brightness. On the one hand, when the flow of people is small, it is easy to cause waste of electric energy. On the other hand, when the weather is good during the day, the brightness display is not enough, but it is easy to display at night or in rainy days. It makes people feel abnormally dazzling, and the viewing effect is poor;
