Design Of A New Landscape Lighting Control System

Control system is the key part of landscape lighting system whose mainly role is lights brightness control intelligently. With the development of landscape lighting, the control system which mainly use DMX512 protocol can not meet the requirements in lights control capacity and intelligence. This paper mainly designed a landscape system with network function by combined network technology with DMX512 protocol where Art-Net protocol was used in network layer. The system made up of ARM9 and FPGA with its control core is ARM9. uCOS II Operation System works in ARM9 which to implement network communication, Art-Net protocol analysis, and GUI users interface. FPGA is used to output four DMX512's signal simultaneity.In this paper, the control system's hardware have been designed,and uCOS II, Lwip, uCGUI and FPGA modue have been debugged. With the advantage of high intelligence and large lights control capacity, this control system is very suiteable for landscape lighting system.
