Abstract_Chinese:为满足流量计校准互联网化和信息化的发展需求, 研究了流量计校准网络的模型．基于流量标准装置运行所产生的数据, 该模型构建了校准网络特有的多反馈多交互结构, 为流量计校准网络监控管理提供了互联网运行机制的支持．基于观察者模式设计了监控系统的结构, 由依据用户身份划分监控内容转变成依据监控内容划分为不同的主题, 用户可以灵活订阅主题的模式．通过WebSocket协议的浏览器与服务器全双工通信功能, 实现了流量计校准网络的互联网实时监控．应用JavaEE架构设计开发了流量计校准网络监控管理系统．该系统成功地运行在流量标准装置上, 取得了较好应用效果．
Abstract_English:The model of flowmeter calibration network is investigated to meet the development demands of networked and informationalized flowmeter calibration. Based on the operation data of flow standard facility，a unique multiple feedback and interaction structure of the calibration network is established with this model，providing a support of the Internet operating mechanism for the monitoring and management system of flowmeter calibration network. Based on the observer pattern，the function structure of the monitoring system is designed，which is transformed from dividing monitoring content by user identity to a mode of dividing monitoring content into different themes to which the user can flexibly subscribe. The real-time Internet monitoring of the flowmeter calibration network is realized through the browser and server full-duplex communication capability of WebSocket protocol. The flowmeter calibration network monitoring and management system is developed with JavaEE. This system is successfully applied to a flow standard facility，and good application effects are obtained.
