摘要
文章讨论了如何通过动态Web技术来实现远程数据实时监测。首先提出了系统的设计框架和硬件组成,在系统软件层的关键技术中,分析了uClinux操作系统,选取Boa作为嵌入式WebServer,重点研究了动态Web技术CGI和Flash的实现机理。最后通过编写CGI程序并结合Flash动画实现了动态Web交互功能,解决了数据在浏览器中的实时刷新和动态描绘问题,人机界面更加友好,数据显示更加直观,成功地实现了远程实时监测功能。
How to realize the long-distance real-time data monitoring by the dynamic web technology is discussed in this paper. Firstly, the design frame and the hardware composition of system are proposed. In crucial technology of software level of system, uClinux operating system is analyzed, then boa is selected as embedded web server and the realizing mechanism of dynamic web technology of CGI and Flash is researched with emphasis. Finally, through compiling the CGI program and the flash to realize the dynamic web interactive function, to solve the problem of real-time for refreshing and dynamic scan data in the browser, and to make the man- machine interface more friendlier, the data display is more direct-viewing, and the function of long-distance real-time monitor is successfully realized.
