中文摘要：
为了实现将IPv6无线传感器网络接入以太网，在分析现有接入系统不足的基础上设计了一套接入系统．在该系统中，设计并实现了基于嵌入式处理器ATmega128、智能射频芯片CC2420以及网络控制芯片RTLS019的接入网关设备．该设备可以将基于IEEE802．15．4的IPv6无线传感器网络接入以太网．采用模块化设计，引入了硬件抽象层和设备适应层相结合的软件驱动模式．说明了系统中数据与协议转换的基本原理．实验表明通过该设备能够灵活地完成网络间通信，具有应用价值．
英文摘要：
By analyzing the deficiency of current access system, a method applicable to access IPv6 wireless sensor networks to Ethernet is proposed, the access system is also Specified. In this system ,a gateway which is used to connect the IPv6 sensor network with IEEE 802. 15.4 with the Ethernet is designed with embedded processor ATmega128, smart RF chip CC2420 and network controller RTL8019. Software modularization is sketched,including Hal-layer software and Device-adaptation-layer software. This paper also illustrates the principle of data forwarding and protocol conversion. Experiments indicate that this system is useful and effective.
