TMSR-SF0 data monitoring and visualization scheme based on digital twin

目前核电运行管理系统存在数据接口不统一、设备状态数字化表达程度差等缺陷,为适应未来智慧核电的需要,将数字孪生理论与实时数据对接技术、图形可视化手段相结合,基于钍基熔盐固态仿真堆(Thorium Molten Salt Reactor-Solid Fuel,TMSR-SF0)实例,提出一套完整的数据监控与可视化技术方案。首先,建立熔盐堆反应装置数字映射模型,并完成在Unity引擎的模型对接及虚拟场景渲染;其次,基于Node-EPICS事件驱动与Socket.io套接字实现时空数据关联;最后,基于XCharts可视化框架提出集中显示实时数据的可视化方法,保证数据的可解释性,便于对数据的实时分析。经实践验证,该方案为TMSR-SF0的数据监控系统开发提供了有效技术支撑,数据更新周期为100 ms,且具备全流程数据采集、网络通信、图元动态展示等功能,有助于操作人员对核反应装置的在线监视与运行管理,为核电领域监控技术的数字化转型发展提供了参考。

[Background]There are some defects,such as inconsistent data interface and poor digital expression degree of equipment status in the current nuclear power operation and management system.[Purpose]In order to meet the future needs of smart nuclear power,a complete set of data monitoring and visualization technical scheme is proposed in this study by combining the digital twin theory with real-time data docking technology and graphical visualization means.[Methods]Firstly,the digital mapping model of simulated molten salt reactor was established,and the model docking and virtual scene rendering were completed in unity engine.Then,the data association between time and space was achieved on the basis of Node-EPICS event-driven and Socket.io.Finally,the visualization method of centralized display of real-time data based on XCharts visualization framework was implemented for the data monitoring system of simulated Thorium Molten Salt Reactor-Solid Fuel(TMSR-SF0)to ensure the interpretability of data and facilitate the real-time analysis of data.[Results]Practical verification results show that the effective technical support for the development of data monitoring system of TMSR-SF0 is provided by this scheme,and the data update interval accelerates to 100 ms.Functionalities,such as data collection,network communication,and dynamic display of pixels are achieved within the framework of this scheme.[Conclusions]It is helpful for operators to monitor and manage nuclear reactor online,and provides a reference for digital transformation and development of monitoring technology in nuclear power field.
