数字孪生北江模型平台建设研究

Research on construction of digital twin Beijiang model platform

为提高数字孪生北江的精细化模拟水平,建设数字孪生北江模型平台,应用云计算、微服务和多任务并行计算等技术,支撑模型算法和实例的统一调度计算并提供接口服务,可实现流域管理“四预”过程下的模型精准适配和高效调用。应用结果表明,数字孪生北江模型平台具备标准统一、分布部署、快速组装、敏捷复用的模型服务能力。目前,数字孪生北江模型平台建设已基本完备,经过北江近年特大洪水的实战应用与验证,模型平台相关成果可推广复用至其他业务化场景。

To enhance the precision simulation capabilities of the digital twin Beijiang,a model platform for the digital twin Beijiang has been constructed.This platform employs technologies such as cloud computing,microservices,and multi-task parallel computing to support unified scheduling and computational algorithms,providing interface services that enable precise adaptation and efficient invocation of models during the“Four Preventions”processes in watershed management.Application results demonstrate that the digital twin Beijiang model platform possesses standardized,distributed deployment,rapid assembly,and agile reuse capabilities for model services.Currently,the construction of the digital twin Beijiang model platform is nearly complete.Following practical applications and validations during recent extreme floods in Beijiang,the outcomes from the model platform can be promoted and reused in other operational scenarios.
