基于B/S模式的嵌入式系统测试方法与实现

The measurement method and implementation of embedded system based on B/S mode

针对分布式测试系统的研发需求,综合网络通信技术、数据库技术以及嵌入式技术等构建了一种基于B/S(Browser/Server)模式的嵌入式测试系统。通过移植Web服务器Boa、轻量级数据库SQLite、网络时钟同步协议NTP(Network Time Protocol),实现了一个完整的测试系统。系统前台采用实时图形化Web页面显示,使用Ajax异步数据传输与后台进行数据通信,实现了页面局部动态刷新,优化人机交互过程。测试系统通过局域网实验验证,取得了良好的效果,符合预期目标,为今后研发基于B/S模式的嵌入式分布式测试系统打下基础,具有一定的参考价值。

Based on the purpose of developing a distributed measurement system, construct an embedded measurement system based on B / S mode which combines network communication technology, database technology and embedded technology. By transplanting the lightweight Boa as embedded web server, transplanting lightweight SQLite as a testing database, transplanting NTP（ Network Time Protocol） to synchronization system time, realized a completely distributed test system based on B / S mode. The front of the system using real- time graphics web page display, using Ajax（ Asynchronous Java Script And XML） asynchronous data transmission with the back of the system, so as to realize local dynamic refresh of the web page and optimize the process of human- computer interac-tion. The measurement system is verified in LAN and it is helpful to develop embedded distributed measurement system based on B / S mode in the future.
