Study Of The Landscape Lighting Control System Based On DSP

Due to the addition of LED in the landscape lighting industry has entered an unprecedented period of growth under the acceleration of China’s urbanization process. In this case, the wired control is applied in traditional landscape lighting, which requires a lot of cable connection and results in higher cost for large scale application.Zigbee wireless technology is introduced into the landscape lighting control system in this paper. A wireless landscape lighting control system based on Zigbee wireless transmission technology is designed. Visual Basic 6.0 is used in a PC.The operator can control LED color and brightness through the PC.The control information of the PC is transmitted through the Zigbee wireless module, and the control information is delivered to the controller through the Zigbee receiver. The DSP C2000 TMS320f28027 is used in controller, and the received control information is decoded into corresponding duty ratio to regulate the LED colors and brightness. The DSP can control 2 road of full-color LED lamp.In this paper, the working principle of landscape lighting system and the wireless networking control method are presented. The hardware and software design process of full-color LED landscape lighting system are proposed. The wireless control technology of wireless landscape lighting are designed and implemented by using PC interface technique.Finally, the system has been tested and the results show that the LED lamp switch, dimming and color control are realized, stable work, can meet the needs of practical application. In the end, summary and outlook to the whole research contents are made.
