摘要
为满足非生产控制区对人机交互的需求,解决客户端/服务器(client/server,C/S)架构下客户端占用资源过多,已有实时数据刷新速度较慢,程序批量部署升级困难等问题,文章提出前后端分离的浏览器/服务器模式(browser/server,B/S)人机展示架构;充分考虑前端展示需求,以分类、分组方式组织可缩放矢量图形(scalable vector graphics,SVG)标签,并补充基于电力系统图形描述规范(CIM-basedgraphic exchange format,CIM/G)自定义属性的图形转换方法,设计基于WebSocket的实时数据推送方法,能够有效提升展示效果;为在B/S人机中展示多种应用数据,规范服务发布/发现机制、消息主题订阅格式及消息通用结构体。文章架构及各种关键技术已应用于B/S人机展示系统中,系统在天津市调控云平台已稳定运行一年,满足非控制生产区高级应用对人机数据展示的需求。
Aiming at meeting the demand for human-machine interaction in the non-production control area and solving the problems that the client occupies too many resources,that the existing real-time data refresh rate is slow,and that the program is difficult to deploy and upgrade under the C/S architecture,a human-machine interface under the B/S(browser/server)architecture is proposed in this paper.Fully considering the front-end display requirements,a CIM/G graphics conversion method is designed for organizing SVG tags in categories and groups with custom attributes,and a real-time data push method is used based on WebSocket,which effectively improve the display performance.In order to display a variety of application data on B/S human-machines interface,the service release/discovery mechanism,the message topic subscription,and the common message structure are standardized.The proposed architecture and key technologies have been applied to the B/S human-machine interface system,and operating steadily for one year on the Tianjin dispatching and control cloud platform,which proves that the B/S human-machine interface can meet the demand for advanced applications in non-controlled production areas.
