一种基于ARM的嵌入式Web服务器的研究与实现

摘要

为了实现将嵌入式设备接入Internet,并可通过Web浏览器对其进行远程访问、管理等操作的目的,文中以Samsung公司的S3C2440AL ARM9处理器作为硬件核心,以Linux操作系统下的Boa服务器作为软件平台,研究并实现了一个嵌入式Web服务器.给出了系统硬件平台结构的设计及组成,详细讨论了Linux操作系统和CGIC库的移植过程,对Boa服务器的建立以及运用CGI实现浏览器与嵌入式Web服务器之间的动态交互技术进行了研究.对该嵌入式Web服务器的实验测试结果表明其响应迅速,运行稳定,满足应用设计需求.%To realize the online remote access and management to the embedded devices using the Web browser over Intemet,an embedded Web server,which takes Samsung corporation's S3C2440AL ARM9 processor as hardware core and Boa server of Linux operating system as software platform,is designed and realized in the paper.The system hardware architecture is presented.The process of the Linux operating system and CGIC library being transplanted to ARM platform is discussed in detail.The realization of Boa and dynamic interaction between Web browser and the embedded Web server by using CGI are especially analyzed.The experimental result of the embedded Web server shows that it responds rapidly and runs steadily,achieves the application purpose.
