嵌入式无线网关系统设计

摘要

Aiming at the problems existing in wireless sensor network, such as short data transmission distance and limited data processing capability, a design scheme of wireless embedded gateway system with S3C2440 processor as the control core, and μC/OS-II as the operating platform is proposed. The systematic architecture, hardware composition and software design are introduced in detail. The test shows that the system features reliable and stable operation, powerful data processing capability and long transmission distance; it satisfies the requirement of engineering application; and has wide application prospect.%针对无线传感器网络存在数据传输距离短和数据处理能力有限的问题,提出了一种以S3C2440处理器为控制核心、以μC/OS-Ⅱ为操作平台的无线嵌入式网关系统设计方案.详细介绍了系统的总体结构、硬件组成以及软件设计.试验结果表明,系统具有运行可靠稳定、数据处理能力强和传输距离远的特点,可满足工程应用的需求,具有广阔的应用前景.
