Research on the Digital Twin System of Supercritical Atomization Crystallization Process

为解决超临界雾化结晶纳米生产工艺中存在设备智能化程度低、安全风险高、生产过程需要人为干预、无法真正实现人机分离等问题,设计一套数字孪生解决方案。通过融合物联网、互联网、数字孪生和虚拟现实等技术,建立数字虚拟生产平台。采用以虚代实、以虚控实、虚实结合的方法,实现生产数据采集与处理的可视化、远程监测、远程遥控、智能预警和生产教学培训等功能。经验证,该方案具有可行性,能有效提升超临界雾化结晶工艺的安全生产水平、降低生产对工人经验的依赖,提升工艺的数字化水平。

To address challenges such as low equipment intelligence,high safety risks,the need for human intervention,and the inability to achieve true human-machine separation in the supercritical atomization crystallization nanomanufacturing process,a digital twin solution was developed.By integrating IoT,the Internet,digital twin,and virtual reality technologies,a digital virtual production platform was established.This platform leverages virtual simulations to control real-world processes,seamlessly combining virtual and physical elements to enable production data collection and processing,visualization,remote monitoring,remote control,intelligent early warning,and production training.Experimental validation confirms the feasibility of this solution,demonstrates its ability to enhance the safety and efficiency of the supercritical atomization crystallization process,reduce reliance on workers’experience,and improve the overall digitization of production.
