| 摘 要： | 网关负责无线传感器网络数据出口，是其重要组成部分。3G网络的到来将为无线数据传输带来新一轮的发展。设计了一款与WCDMA网络相结合的无线传感器网络网关，采用以LPC2148ARM7芯片为核心，与无线射频芯片及华为EM770W模块组成硬件系统；以μC／OS-Ⅱ作为实时操作系统，自主编写合适的通信协议及路由算法，尽可能的使网关处于休眠状态，并进行了相关实验。试验结果表明：本网关具有网络传输速率快、低功耗、丢包率低等特点。

| Abstract: | The gateway, responsible for data export, is an important component in a wireless sensor network （WSN）. The arrival of 3G networks will bring a new round of development for wireless data transmission. A WSN gateway was designed combining with the WCDMA network, which used LPC2148 ARM7 chip as the core, and adopted wireless RF chip and Huawei EM？？0W module to constitute the hardware system. It used μC/OS-Ⅱ as the real-time operating system, and autonomously developed appropriate communication protocol and routing algorithm to keep the gateway in sleep state as far as possible. The related experiment results show that the gateway possesses low consumption power and packet loss rate with a relatively high real-time data transmission rate. |
