基于嵌入式控制器和RS485的智能家居系统

现代生活中,人们对居家生活的智能化以及舒适度有了更高的要求.但是目前大部分智能家居系统功能并不是很完善,而且价格高昂.针对这种情况,设计了基于RS485总线,以嵌入式控制器为主设备,将接入的无线信号收发模块和执行控制检测反馈模块作为从设备的智能家居子网系统,并给出了整体框图.上位机采用LabVIEW软件实现,通过串口接收执行控制检测反馈模块所采集到的数据,实时显示控制效果.真正地实现了基于嵌入式控制器和RS485总线的功能易扩展、可靠性高、价格实惠的智能家居系统.

Intelligent home system based on embedded controller and RS485

In modern life, people have higher requirements on intelligent and comfortable degree of home life. But intelligent home systems are expensive and their most functions are incomplete. In order to fit this situation, an intelligent home sub-network system is designed,which is based on RS485 bus,with the embedded controller as master device, and with wireless signal transceiver module and executive control detection feedback module as slave devices. In addition,the general diagram is also given. The upper machine using LabVIEW software, through the serial port, receives the data which is collected by executive control detection feedback module, to display the real-time control effect. Thus,an intelligent home sub-network system based on embedded controller and RS485 bus is truly accomplished and its functions can be extended easily,which has high reliability and can be affordable.
