智能照明系统KNX与DALI协议网关的设计及实现

Design and implementation of intelligent lighting systems KNX and DALI protocol gateway

摘要:

基于DALI的智能照明系统以其专业、灵活和低成本得到了广泛的应用,但同时DALI照明系统由于组网规模小等缺点限制了它的推广和应用。KNX总线作为智能楼宇先进技术近年来得到广泛的关注,并在国内外大型公共设施成功应用。结合DALI和KNX系统各自的特点,设计一种基于DALI和KNX通信协议的网关,完成DALI协议和KNX协议的相互转换,实现KNX系统和DALI智能照明系统的融合。介绍了网关的总体架构,系统软硬件架构设计,并对网关功能和性能进行了测试。

Abstract:

Digital Addressable Lighting Interface (DALI) intelligent lighting system have been widely used for its specialty, flexibility and low cost, but at the same the small size of the DALI lighting system and other shortcomings limit its extension and application. As an advanced intelligent building technology, the KNX bus has been paid as much attention in recent years, and successfully applied in domestic and large public facilities. By combining with the characteristics of DALI and Konnex (KNX) system, designing a gateway based on DALI and KNX communication protocol can complete the DALI protocol and KNX transformation, and realize the integration of KNX system and DALI intelligent lighting system. This paper introduces the overall architecture of the gateway, the design of system software and hardware architecture, and the test of gateway’s functionality and performance.
