摘要
文章设计了一种无线传感网络网关。该网关具有多网接入能力,可提供以太网、CDMA、WiFi和ZigBee四种不同的网络接入方式,同时实现网络之间的互联互通。网关的硬件平台分两个部分——核心板和底板——分别进行设计。核心板是一个最小嵌入式系统,包括处理器和存储器,其中处理器采用三星公司的S3C6410,最高速度可达667MHz,底板集成多种设备接口,便于与不同的外设和通讯模块连接。网关应用软件采用C语言在Linux系统下实现。
A gateway of wireless sensor net is designed in this paper.The gateway has a capability to access mullti-network.It offers four kinds of different network access methods for Ethernet,CDMA,WiFi and ZigBee and can realize the interconnection between those networks.The gateway hardware is divided into two parts： the core board and the bottom board to designe.The core board is one of the smallest embedded system,including processor and memory,where the Samsung S3C6410,maximum speed up to 667MHz.And the bottom board integrated a variety of device interface to facilitate connection with the different peripherals.The application software of gateway is programmed in C language and is based on the platform of Linux operation system.
