电力载波在智能家居内部网络中的应用

家庭内部网络把智能家居系统中所有的设备有机地结合起来,是实现系统中信息传递的有效途径。目前,多数家庭网络都使用以太网、电话线或无线方式进行组网,但是以太网、电话线布线不方便,无线网络成本相对较高。为了解决以上组网方式的不足,分析了家居系统的电力线具有电力载波通信能力,选择以电力线作为智能家居系统内部网络通信媒介,使用了MI200E载波芯片设计出一个电力载波通信模块,详细地介绍了其硬件设计和软件控制流程。采用电力载波技术作为组网技术,不仅简化了布线,而且有效地降低了系统成本。

Design and Research of Smart Home System

The home network which combines organically all devices of the smart home system is an effective way which carries out information transmission.At present,most of the home network has network constructing by Ethernet,telephone lines,and wireless,but the wiring of Ethernet or phone line is not convenient,and the cost of wireless network is relatively high.In order to slove these disadvantages of this above network constructing,analyzed that power lines in smart home system has communication capability by Power Line Carrier,selected power lines as the internal network communication medium in smart home system,designed the communication module of power line carrier with MI200E carrier chip,introduced the hardware design and software control process for this module in detail.The using of Power Line Carrier technology as network constructing technology,which is not only simplified the wiring but also reduced the costs of this system effectively.
