以无线传感网重大专项为依托,介绍了一种基于ARM处理器和Linux操作系统的网关.网关在实现无线通信、串口通信、以太网通信、2G/3G通信以及实现自身与数据采集节点无线通信协议的前提下,在硬件和软件设计上都采用了模块化的理念,硬件上可根据实际需要搭配多种不同频率的无线通信模块、GSM/GPRS模块;软件上基于Linux操作系统,尽可能使系统进入休眠模式,以使功耗降低.测试表明,该网关具有实时传输能力强、丢包率低、功耗低、硬件模块可变、二次开发方便、通用性强等特点.

Based on major special projects of national science and technology,this paper describes a gateway used in wire?less sensor network which is implemented based on ARM processor and Linux OS. On the premise of wireless data collection, data processing and serial port,ethernet,2G/3G and WiFi data output,the gateway adopts concepts of modular design in both software and hardware. According to actual requirements,the hardware can adopt wireless communication data accessing module at different frequences,2G/3G module or WiFi data output module. And the software based on Linux OS is configured into sleep mode as long as possible. Tests show that the gateway is characterized by real?time transmission,low packet losing rate,low power consumption,pluggable hardware module,secondary development and good versatility.
