【摘要】：随着我国城市化进程加快，景观照明行业进入了前所未有的发展高峰期。近几年LED技术取得了突破式发展，在色度方面已实现了可见光波段的所有颜色，并成为改变全球照明业格局的新兴光源。电力线载波（PLC）通信作为信息传输媒介的一种通信方式，其稳定的应用条件和良好的应用前景以及潜在的巨大市场已被人们所关注。论文基于PLC技术设计了采用LED的景观照明控制系统。论文简要介绍了PLC技术和PLC调制解调模块的硬件结构，讨论了将上位机命令通过PLC总线下达到PLC主动板设计问题，重点设计了综合PLC技术与PWM调光技术的RGB驱动板，实现了RGB LED灯的调光控制；着重编写了RGB驱动板软件，包括PLC侦听、PLC数据发送/接收、色彩调度、色彩方案下载、色彩同步、在线测试等模块，并编写了上位机的景观照明控制系统软件。论文工作实现了景观照明控制系统的四大功能：（1）按照色彩方案自动运行；（2）通过上位机下载色彩方案，，更换景观照明效果；（3）通过上位机在线测试RGB LED灯的效果；（4）实现多个RGB驱动板的同步运行，呈现一致的景观照明效果。论文设计的景观照明控制系统通过了实验室测试，并在多个用户手中进行应用测试，结果表明，景观照明控制系统设计思路新颖，即插即用，稳定可靠。
[Abstract]:With the acceleration of urbanization in China, landscape lighting industry has entered an unprecedented peak period of development.In recent years, LED technology has made a breakthrough development, and has realized all the colors of visible light band in chroma, and has become a new light source to change the pattern of global lighting industry.Power line carrier carrier (PLC) communication as a communication mode of information transmission media, its stable application conditions, good application prospects and potential huge market has been paid attention to.Based on PLC technology, a landscape lighting control system based on LED is designed in this paper.This paper briefly introduces the hardware structure of PLC technology and PLC modulation and demodulation module, discusses the design of PLC active board by PLC bus, and focuses on the design of RGB driver board which integrates PLC technology and PWM dimming technology.The dimming control of RGB LED lamp is realized, and the software of RGB driver board is written emphatically, including the module of transmitting / receiving RGB data, color scheduling, color scheme downloading, color synchronization, on-line testing and so on.The software of landscape lighting control system of upper computer is written.In this paper, the four main functions of the landscape lighting control system: 1: 1) automatically running according to the color scheme, (2) downloading the color scheme through the upper computer, are realized in this paper.Changing landscape lighting effect / 3) realizing synchronous operation of multiple RGB driver boards by on-line testing RGB LED lamp by upper computer, showing consistent landscape lighting effect.The design of the landscape lighting control system has passed the laboratory test, and has been applied to many users. The results show that the design idea of the landscape lighting control system is novel, plug and play, stable and reliable.
