Research And Applications Of Web Server Based On Embedded Linux And Sqlite

Embedded devices with the advantages of high performance, small size, low power consumption appeared in the aspects of our lives. With the rapidly growth of internet, embedded devices with a combination of the internet become a trend in the development of embedded devices, and make it has the complex functions,such as remote monitoring and management and so on.The embedded web server technology has been developed rapidly just in this trend.. How embedded devices to access the network, and how effectively and conveniently to control and manage the embedded devices attached to the internet?Around the theme discussed above, this paper proposesed a solution which is to add an embedded WEB server to the embedded system. With the help of internet and browser, this kind embedded system can realize the remote monitoring function. The article discusses in detail the embedded WEB server design, implementation and application content. The detailed work this paper finished include:a brief introduction of the embedded systems, the situation of embedded Web server and structures of the related technologies in the embedded WEB server development; a detailed analysis of related technologies used in embedded WEB server,this aspect including:TCP/IP protocol, HTML forms, dynamic page, and SQLite database; This paper also realize a embedded WEB server. The implementation process include:compiler and transplantation of the Linux, analysis and compile and transplantation of the SQLite database,the source code analysis and compile and transplantation of the BOA sever, use of busybox to produced a JFFS2root file system; With the analysis of the embedded Web server above, the article also designed a practical application of the embedded WEB server, the application of embedded WEB server realize the function of the water quality monitoring.
