摘要
为了实现DCS产品的跨广域网监控功能,并降低工程应用成本,提出一种由浏览器端程序直接解析显示DCS监控界面文件的方法。基于现代浏览器对HTML5标准的良好支持,结合Canvas绘图技术、WebSocket实时通信技术、SharedWorker跨页面数据共享技术等,设计出一套完整的DCS跨广域网监控解决方案,并对系统架构以及核心模块的主要功能和工作流程做了详细说明。基于此方案,为EDPF-NT+产品开发了Web扩展组件,该扩展组件可直接解析渲染EDPF-NT+监控界面文件,在使该DCS产品具备跨广域网监控能力的同时,降低了工程实施成本,实现了与原生界面一致的功能与用户体验。该扩展组件在多个工程项目中应用,取得预期效果。
In order to realize the monitoring across WAN for DCS products and reduce the engineering application cost,an idea of directly parsing and displaying the DCS monitoring interface files by the browser-side program is proposed.Based on the great support from modern browsers for the HTML5 standard,and combined with Canvas drawing technology,WebSocket real-time communication technology,SharedWorker cross-page data sharing technology and others,a complete DCS monitoring across WAN solution is designed,and the system architecture and the main functions and workflows of core modules are explained in detail.Based on this solution,a DCS extension component is developed for the EDPF-NT+product.The extension component can directly parse and render the EDPF-NT+monitoring interface files,which enables the DCS product to have the monitoring across WAN capability while reducing the engineering implementation cost and achieving the same function and user experience as the original interface.The extension component has been applied in multiple projects and achieved expected results.
