摘要: 组态平台是自动控制系统监控层一级的软件平台和开发环境,能以灵活多样的组态方式(而不是编程方式)提供友好的用户开发界面和简捷的使用方法,其预置的各种软件模块可以非常容易地完成监控层的各类任务,用户甚至可以不写一行代码就能搭建自己的控制系统。 现代企业的生产已经趋向国际化、分布式,Internet将是实现分布式生产的基础。为了使组态平台能够更好地在Internet环境下工作,采用B/S架构来实现组态平台,特别是基于HTTP协议进行数据通信,是比较有意义的尝试。 本文根据分布式生产对监控系统的需求,讨论了实现基于B/S架构的组态平台所需要的关键技术,其中包括客户端和服务器端之间基于HTTP协议的数据通信模式,客户端基于SVG和JavaScript的数据呈现技术,发布订阅模式中订阅条件的匹配,实时条件下的服务质量控制。这些技术涵盖了组态平台从数据通信到数据呈现的各个方面。 在上述研究工作的基础上,本文设计并实现了基于B/S架构的组态平台Hawk,并通过Hawk在实际项目中的应用,验证上述研究工作的有效性和可行性。最后,结合实际应用情况,本文对Hawk的设计和发展方向提出了进一步的建议和展望。
英文摘要: Configuration platform is a software platform and development environment on monitoring layer for autocontrol system. It provides convenient user interface which is easy to use based on flexible configuration choices, and whose pre-installed modules can easily complete the monitoring tasks in the diverse environment. Users can even construct a monitoring system without writing any code. Modern production tends to be more and more international and distributed. Internet has become the foundation for the distributed production. Implementing a configuration platform which works in the Internet environment and uses B/S architecture,especially with data communications based on HTTP,is worthwhile to try. Based on the monitoring system’s requirement from today’s enterprise,the paper talks about the key technologies of a configuration platform based on B/S,including communication mode and technologies based on HTTP protocol between server and client,data displaying technologies based on SVG and JavaScript on the client,ECA rules for subscription matching in subscribe/publish model ,QoS guarantee in real-time monitor.These technologies cover various aspects from the web server to the client. Based on these studies,this paper designs and implements a configuration platform named Hawk,and tests the studies feasibility through the application of Hawk in actual projects. Finally, based on actual application, the paper made some suggestions and expectations on Hawk’s design and evolution in the future.
