摘要(Abstract)：
设计一种室内环境信息采集系统。系统中单片机STM32F103ZET6和STM32F103RBT6分别作为中央节点控制器和局部节点控制器并通过湿度传感器、光照传感器、PM2.5传感器、烟雾传感器、步进电机、音乐模块、语音模块控制器来完成温湿度、光照度、PM2.5的采集与显示、背景音乐的播放控制、室内灯光的自动调节、室内百叶窗控制。由于需要采集和控制客厅、卧室、厨房等建筑单元的环境参数,故采用分布控制式控制系统,每个建筑单元的采集、控制节点以及中央控制器和局部控制器都挂在CAN总线上,所以其具有模块化、可扩展的特点并能实现各控制器之间的通信。经过实际调试和运行结果表明,该系统可达到设计和教学要求。
