With people's attention to and participation in sports, large-scale and comprehensive gymnasiums have sprung up nationwide. Unlike previous small gymnasiums, large modern gymnasiums have more robust functions, more intelligent control, and humanization. However, some shortcomings remain, such as too centralized control and inflexible control. Therefore, intelligent control and energy saving of lighting will become the development direction of lighting systems. To ensure the normal progress of sports events and the quality of TV broadcast, the requirements of gym lighting are increasingly stringent, so the lighting control system of gyms has higher requirements accordingly. To solve these problems, this paper designs a gym intelligent control lighting system based on LED bus, which can adapt to the corresponding lighting scenes of different venues. The experimental results show that the intelligent lighting control system designed in this paper can run normally and stably, and can complete the detection of crucial working parameters. This system can automatically control the light and dark and switch off according to the indoor lighting brightness, achieving a sound energy saving effect, improving the lighting environment, and achieving the desired goal.
