【摘要】 随着网络和Web技术的发展,实时监控系统也在借助Web技术,提供分布式、轻客户端的监控服务,从而使得基于Web的远程实时监控技术成为当前计算机应用的新的热点技术之一。 论文结合一个电力监控软件系统(YSS)开发的实际需要,对基于Web的数字监控系统技术进行了较为详细、深入和全面的研究,给出了一个基于SVG+XMLHTTP+Javascript技术的实时数据动态Web发布模型,并将其成功地应用于YSS系统的基于Web的监控功能的开发。论文探讨了如何采用Web Service和CORBA分布对象技术建立系统架构,使系统具有较强的可扩展性和与其它系统的易集成性。此外,论文还详细讨论并给出了包括折线、电流表、控制按钮等在内的各种数字监控图形界面元素的支持SVG的对象模型,对类似系统的研发具有较大的参考意义。更多还原

【Abstract】 With the advances of technologies of network and WWW, real-time supervising systems are also beginning to have distributed and thin clients with the help of Web technologies. Web based remote real-time supervising technologies have emerged as hot researches.To meet the need of constructing a real power supervising system (YSS), some technologies of Web based digital supervising network are studied in this thesis deeply, completely, and in detail, and based on these studies, a dynamic real-time data publication model using SVG+XMLHTTP+Javascript is presented, and is also applied successfully in developing the Web based supervising functions of YSS system.. Topics of how to design the system’s architecture using Web Service and CORBA to improve its scalability and ability of integrating with other information systems are also discussed in the thesis. Moreover object models of various elements of GUI including polyline, virtual ampere meter, button, etc., supporting SVG for digital supervising are studied and presented, they are useful to other similar research project.更多还原
