The Control Method Of LED Screen Based On ARTNET Protocol And Ethernet Protocol

Landscape lighting is an important direction of development of lighting technology.Landscape lighting is closely related to urban economic,cultural,social and natural factors,and plays an important role in shaping the overall image of the city.Landscape lighting has been developing rapidly in recent years.Among them,LED lighting screen technology is loved by many industries because of its excellent rendering power and practicability.LED lighting screens have great market value,but today's domestic LED lighting screen technology is slow to support large lighting projects,especially the back-end control.In order to meet the needs of the market,the development of LED lighting technology is very necessary.This thesis aims to provide a new LED lighting screen control method based on traditional lighting screen control technology and drawing on foreign technical experience.This scheme uses Ethernet technology to build local area network to realize fast data transmission,and based on the ARTNET protocol and DMX512 protocol to achieve the transfer and analysis of the light data between the host.Design of a control method will be a combination of FPGA and STM32.It achieves a doubling of the number of luminaire controls and control effects under limited resource conditions.This scheme mainly focuses on real-time dynamic playback function.At the same time,it designs a variety of practical function optimization system capabilities.In the scheme,it also develops PC-aided product debugging and function demonstration.In the scheme,the host computer auxiliary product debugging and function demonstration are also developed.Optimize the overall control framework with sophisticated software and hardware design.It also improves real-time communication capabilities,large data volume processing and fast information decoding capabilities in lighting screen control.The scheme enables the resources to be used reasonably and can better support large-scale LED lighting projects.With the development of smart city and smart lighting concept,LED lighting screen will surely shine brightly.
