针对移动互联网多接口终端以及现代家庭物联网的广泛接入与控制问题,提出基于智能网关,具有多终端兼容多通信方式的智能数字家庭系统.在多通信方式下,研究UDP和TCP/IP等协议转换以及异构数据的处理,内网采用ZigBee和电力载波通信.采用基于电力载波的通信方式免去了通信布线问题,改进电力载波协议X10解决现代家庭控制与获取数据增大的问题; 集中控制模式可减少多设备控制所产生的数据量,有利数据传输.系统采用模块化设计,包括智能网关模块、电力载波模块、ZigBee模块和其他应用模块. 据此实现的展示模型,验证了该系统的有效性.

To overcome shortcomings of current smart home systems and insufficient power line carrier data transmission capacity, a smart home system based on intelligent gateway is studied in this paper.The system includes internal networking, intelligent gateway, and external networking. Multiple servers are designed in the gateway. The servers start at the same time and receive various forms of data, which are processed into an internal network format.There is also an external network that includes several communication modes such as TCP/IP, UDP and pipe. The internal network includes ZigBee and power line carrier(PLC)communication. Power line carrier protocol is improved to expand data transmission capacity to accommodate communication needs of a modern family.The smart home system is designed in modules, such as intelligent gateway module, power line carrier communication module, ZigBee wireless communication modules and appliacations within electrical equipment and appliances.Finally, this system is physically designed and verified.The smart home system introduced in this paper is easy to use and has strong compatibility.
