摘　　要：针对现有城市景观灯控制系统控制范围小、管理效率低、灵活性差的问题,提出一种城市发光二极管(LED)景观灯智能控制系统,采用基于脉冲宽度调制调光技术的智能控制终端,使用RS485总线实现LED灯管的终端通信,并通过通信转换器接入以太网网络与远程控制中心相联,实现远程智能控制。阐述智能控制终端的硬件电路设计、软件设计流程、系统通信协议和远程控制实现方法。测试结果证明,该系统数据传输可靠、响应及时、成本低,易于实现分布式远程控制和管理。[Abstract] To solve the problems of limited control range, low management efficiency, low-flexible for urban landscape lighting control system and to realize intelligent remote control, this paper proposes an intelligent control system for Light Emitting Diode（LED） landscape light, which includes an intelligent control terminal based on Pulse Width Modulation（PWM） dimming technology, and a remote communication system integrating RS485 bus, communication converter and Internet network. This paper presents the hardware circuit design and software design process for intelligent control terminal, system communication protocol and remote control methods. Experimental results demonstrate that the control system has features of reliable data transmission, fast response, low cost, and it is easy to realize the distributional long-distance control and management.
