摘　　要：针对目前DALI系统中传感器安装分散、系统控制不灵活、参数配置不方便的问题,提出了一种以SN32F248微控制器为核心、以μC/OS-II操作系统为平台、带有多种传感器的控制设备设计方案。利用Wi Fi芯片ESP8266,实现了对控制设备的无线配置与查询。红外遥控器配合多传感器的使用,实现了系统的模式切换、场景切换与灯光控制等功能。通过μC/OS-II在SN32F248上的移植以及信号量机制的建立,解决了任务间的通信、任务的调度问题,实现了实时操作系统的功能。In view of the current DALI system sensor decentralizing installation, inflexible system controlling and inconvenient parameter configuration problem, this paper proposes a SN32F248 microcontroller as the core, the μC/OS-II operating system as the platform, control equipment design with multiple sensors. WiFi chip ESP8266 is used to realize the wireless configuration and query of control equipment. Infrared remote control with the use of multiple sensors achieves a system of mode switching, scene switches and lighting control. The establishment of μC/OS-II in the SN32F248 transplantation and semaphore mechanism solves the scheduling problem of communication between tasks, and realizes the real-time operating system.
