摘要
为了确保数字可寻址调光接口(Digital Addressable Lighting Interface,DALI)系统的兼容性,进一步提升智能化照明控制效果,系统地研究了DALI 2.0标准的接口线路及协议。设计了内置总线电源及接口电路的DALI 2.0主控器,并设计了配套的PC上位机软件。提升了主控器的自主运行能力,使主控器成为照明系统的“大脑”。实施了包含主控器、照度传感器及LED驱动装置的照明系统实验。结果表明,主控器自动处理照度传感器的事件报告并自主控制环境照明亮度,达到了智能管理、降低照明能耗的效果。
To ensure the compatibility of Digital Addressable Lighting Interface(DALI)system and improve the smart lighting control effect of the system,this paper systematicly studies the interface circuit and protocol of the DALI 2.0 standard.A master-controller with a builtin bus power and interface circuit is designed,and a PC software match by the controller is designed as well.The ability of autonomous of the master-controller is enhanced to make it become the“brain”of the lighting system.An experiment with master-controller,light sensor and LED driver is proposed.The experimental results show that the master-controller automatically processes the event report of the light sensor and controls the illumination brightness,which achieves the effect of intelligent management and reduces lighting energy consumption.
