摘　　要：介绍了1种基于数字可寻址照明接口(DALI)协议的多功能从机的设计,在实现DALI通信及调光功能的基础上,提出了安全高效的供电方案,以及照明终端功率因数和LED驱动器工作参数的监测方法,从而在保障从机可靠运行及实现调光的前提下,进一步为照明系统的节能策略提供原始数据,并对照明设备是否故障及故障位置做出准确判断。A design method of multifunctional DALI slave unit was introduced. On the basis of DALI communication and dimming, safe and effi cient power solution was proposed. In addition, the monitoring methods about power factor of lighting equipments and working parameters of LED driver were described. Based on these design, the slave unit can operate reliably and can provide the raw data for the lighting system's energy saving strategies, what's more, the lighting equipments' operating state and fault location can be judged accurately.
