在分析现有照明网络结构的基础上,充分考虑了有线连接方案和无线连接方案各自的优缺点,提出一种结合了有线网络和无线网络的集成网络解决方案,以期达到有线网络和无线网络优势互补的目的,并最终实现了在Zig Bee协议栈中实现DALI协议的集成网络解决方案。该集成网络能兼容于当前主流的DALI协议和Zig Bee专用于照明领域的Zig Bee Light Link(ZLL)协议。相对于传统的ZLL网络,集成网络可以在不降低系统便捷性和用户体验的前提下,使节点控制单元的成本减少2/3以上,极大降低了智能照明系统的建设成本。另外还利用Lab VIEW为该集成网络设计了操作简单、界面友好、美观的用户交互软件,并最终完成了一个基于集成网络的完整照明控制系统。
In this article, based on the analysis of existing lighting network structure, and taking full consideration of the advantages and disadvantages of wired and wireless connection scheme, a method combining wired and wireless network as integrated network was put forward in order to achieve complementary advantages of the wired and wireless networks. An integrated network was implemented by applying DALI protocol in ZigBee stack. It is compatible with the DALI protocol and the ZigBee Light Link (ZLL) protocol which is dedicated for the field of illumination. Compared with the traditional ZLL network, the integrated network can reduce more than 2/3 of the control unit cost of the node without reducing the convenience and user experience, so it can greatly reduce the cost of intelligent lighting system construction. A user friendly software was also designed by using LabVIEW. At last a entire lighting control system based on the integrated network was completed.
