基于802.11协议无线网络的嵌入式远程测控系统研究

Research on embedded remote measurement and control system based on 802.11 protocol wireless network

针对远端设备状态的远程测试与图像监控,把嵌入式技术结合到远程测控系统中,提出了基于802.11协议嵌入式网络的远程测控系统的设计方案。系统硬件平台的核心处理器选择ARM9系列的S3C2440A芯片,并通过基于802.11协议的USB网卡接入网络完成信息传输。系统的软件平台选择嵌入式Linux操作系统,并搭建了嵌入式Web服务器,以实现基于B/S模式的图像远程监控功能。经实验验证,系统可以实时可靠地完成基于802.11协议网络的嵌入式远程测控功能。

For the remote testing and image monitoring of the far-end equipment status,the design scheme of the remote measurement and control system based on 802.11 protocol wireless network is proposed by combining the embedded technology in remote measurement and control system. The S3C2440 A chip of ARM9 series is chosen as the core processor of the system hardware platform,and the information transmission is accomplished by USB card access network based on 802.11 protocol. The embedded Linux operating system is chosen for the system software platform. The embedded Web server was established to realize the image remote monitoring function based on B/S accessing pattern. The experimental results prove that the system can reliably realize the embedded remote measurement and control function based on the 802.11 protocol network in real time.
