摘　　要：目前家庭通用的网络接入设备是基于RJ45接口的,这种链接方式在浪费资源的同时也缺乏便携性。为了解决以上连接方式的不足之处,设计了一种基于电力线通信技术与USB/以太网技术的便携式网卡。该装置采用符合HomePlug AV协议的INT6400芯片来实现电力载波部分的设计,实现家庭互联网数据在现有电力线上的传输,同时使用AX88772B芯片设计USB/以太网转换部分,实现了用USB接口接收网络数据。电力载波通信技术可以实现只要有电力线的地方就有网络数据,而USB接口的方式使得系统适用范围更广,二者相结合实现了网络连接设备的便携化与通用化。At present,the universal network access devices in home,which is based on the link of Ethernet of the RJ 45 inter- face, and this link way is not only wasting resources but also lacking of portability at the same time. In order to solve the problem of the connection mode, a kind of probable network card based on power line communication and USB Ethernet technology is designed. Int6400 chip conforming to home play AV protocol is used to realize the design of power line carried part, and achieve home internet data transmission in the existing power line. At the same time, the use of AX88772B chip design USB/Ethernet conversion part, USB interface is used to receive network data. The technology of power carried com- munication can realize the condition that where there is power line,there is internet data.USB interface makes the system more universal, and the USB interface makes system have wider application.And the combination of the two methods can re- alize the portability and generalization of the network connection.
