摘　　要：针对传统色谱软件功能不完善、兼容性不足、算法性能不高的问题,利用Web技术,设计并实现了一种在线工业色谱虚拟仪器。使用了浏览器+Web服务+仪器通信服务+算法SDK的架构,浏览器使用WebSocket技术实现虚拟仪器监控面板及色谱信号实时渲染;Web服务与仪器通信服务分离提高系统稳定性,设计了三级消息格式用于数据交换;利用并发模型实现了一个性能良好的算法SDK提供数据分析功能,支持多任务同时运行。测试结果表明,文中设计支持多平台运行、性能稳定,适用于工业色谱实验场景。Aiming at the problems of traditional chromatographic softwares with incomplete functions,poor compatibility and low algorithm performance,an online industrial chromatography virtual instrument based on web technology was designed and implemented.The architecture of browser+Web service+instrument communication service+algorithm SDK is used.Browser uses WebSocket technology to implement virtual instrument monitoring panel and real-time rendering of chromatographic signals.Instrument communication services are separated from Web services,and a three-level message format is designed for data exchange.A good-performance algorithm SDK is implemented to provide system data analysis functions,which support multi-task operation at the same time.Test results show that the design supports multi-platform operation and stable performance,and is suitable for industrial chromatography experiments.
