| 摘 要： | 从节能的角度出发,采用改变灯具的工作方式,以达到节能的目的.以DALI(数字可寻址照明接口)协议为基础,通过与传统DALI控制系统做比较,介绍了基于飞思卡尔MC9S12DG128单片机为控制芯片的DALI控制器和镇流器的硬件与软件设计和基于VC++的上位机控制软件的设计.通过使用RS-485总线对DALI控制器进行编址,实现一台PC机与多个DALI控制模块的通信.从而使得一台PC机能够远距离对相对无穷多个灯具进行单个或组群的开关和调光控制.

| Abstract: | From the viewpoint of energy saving,this paper pointed out that it could change the working mode of lighting to save energy.Based on the DALI（Digital Addressable Lighting Interface） protocol,by comparison with traditional DALI control system,introducing the software and hardware design of DALI controller and ballast based on MC9S12DG128 and PC control software design based on VC ＋＋.By using the RS-485 bus to address the DALI controller,PC communication with multiple DALI control modules were achieved.Making the PC can power switch and dimming control more lighting in long distance. |
