LED DISPLAY SYSTEM AND CONTROL METHOD THEREFOR

摘要

An LED display system and a control method therefor. The system comprises multiple LED display unit boxes (1, 2, 3, 4). The LED display unit boxes (1, 2, 3, 4) each comprise a receiving card, a monitoring card, a sensing unit, and a cooling device. Apart from being connected to the receiving card, the monitoring card is also connected to the sensing unit and the cooling device. The method comprises the following steps: S1) sending a monitoring detection command; S2) returning a monitoring detection result; S3) processing the monitoring detection result and performing control. The LED display system processes monitoring detection data of each the unit box (1, 2, 3, 4), carries out comprehensive consideration, and adjusts the brightness of the LED display unit boxes (1, 2, 3, 4) and the rotational speed of the cooling device.
