基于TCP/IP及DALI总线技术的智能照明控制系统

Intelligent Lighting Control System Based on TCP/IP and DALI Bus Technology

针对传统照明管理不便、布线繁杂以及智能化程度低的缺点设计了一套基于TCP/IP及DALI总线技术的智能照明控制系统。系统由智能控制面板、TCP/IP-DALI网关、DALI灯具节点以及传感器节点组成。智能控制面板实现照明系统的集中控制与管理;TCP/IP-DALI网关完成DALI协议和TCP/IP协议的相互转换,实现DALI系统接入以太网,弥补了DALI系统规模小的缺点;传感器节点根据周围环境照度变化与人流量分析节点数据,控制灯具亮度的自动调节,从而实现照明系统的自适应以及低功耗的控制。实验表明系统具有完善的控制方式,良好的照明效果,满足智能照明系统的要求。

In view of the disadvantage of traditional lighting management inconvenience,wiring complex and low intelligent level. A set of intelligent lighting cnntrol system is designed based on TCP/IP and DAL1 bus technology. The system consist of intelligent control panel ,TCP/IP-DALI gateway,DALI lighting nodes and sensor nodes. The centralized control and management of the light- ing system for the intelligent control panel. The conversion of the DAL1 protocol and the TCP/IP protocol is accnmplished by the TCP/IP-DALI gateway. DALI system achieve access to Ethernet. The small-scale shortcomings of the DALI system are compensa- ted. According to the data of ambient illumination change and human traffic are analyzed by Sensor nodes, The. brightness of lamps are adjusted antomatically,thus self_adjustment and low-energy costs control of lighting system is aceomplished. The experiment demnnstrates system has perfect control method,good lighting effects,and meet the requirements of intelligent lighting systems.
