摘　　要：为实现数字孪生系统的快速构建,对自动化生产线积累的大量孪生模型进行高效的重用是最有效的途径之一。针对现有方案在建模效率和信息重用框架上的不足,对面向全流程的数字孪生系统快速建模方法进行了研究。基于待研究对象多样化的特点,先通过多级最长公共子序列的相似度度量方法获取对象特征,同时优化算法设计来发掘典型工艺流程,并进一步提出一种信息重用策略,集成典型工艺流程的有效信息,以支持信息的继承和重构,实现该类问题的多方位、全流程优化设计。最后以断路器数字孪生车间为例进行验证,结果表明,相比传统的搭建方法,这种孪生系统架构方法综合考虑重用方法的客观性和灵活性,实现了在数千模型数量下达到不小于40%的综合优化效率,实际项目开发周期可缩短50%,显著提升孪生模型的构建效率。In order to realize the rapid construction of digital twin system,it is one of the most effective ways to efficiently reuse a large number of twin models accumulated in automated production lines.Given the deficiencies in modeling efficiency and information reuse frameworks of existing solutions,research has been conducted on rapid modeling methods for digital twin systems oriented towards the entire process.Based on the characteristics of the diversity of the objects to be studied,the object features are obtained by the similarity measurement method of the multi-level longest common subsequence,and the algorithm design is optimized to explore the typical process flow,and an information reuse strategy is further proposed to integrate the effective information of the typical process flow to support the inheritance and reconstruction of information,so as to realize the multi-directional and whole-process optimization design of this kind of problem.Finally,the circuit breaker digital twin workshop is taken as an example for verification,and the results show that compared with the traditional construction method,the twin system architecture method comprehensively considers the objectivity and flexibility of the reuse method,and achieves a comprehensive optimization efficiency of no less than 40%under the number of thousands of models,and the actual project development cycle can be shortened by 50%,which significantly improves the construction efficiency of the twin model.
