摘要
文章针对当前航空航天等高安全、高可靠领域嵌入式软件的测试验证严重依赖专用硬件环境、测试充分性难以保证等问题,立足于处理器虚拟化仿真、分布式总线、基于FMI的联合仿真等技术方案,提出基于全数字仿真的复杂系统数字孪生环境构建方案,并对数字孪生技术的国内外发展现状进行了介绍,详细阐述了基于全数字仿真的复杂系統虛拟化仿真环境构建方案,通过对空间站某舱段多.个配置项的系统级虛拟化仿真实例验证了方案的可行性,相关研究成果和方法已在空间站、某型号控制系統得到应用,具有较强的工程实用性。
In view of the current aerospace and other high-safety and high-reliability embedded software testing and verification issues that rely heavily on dedicated hardware environments,and the test adequacy is difficult to ensure,based on processor virtualization simulation,distributed bus,FMI-based co-simulation and other technologies,the paper proposes a digital twin environment construction scheme for complex systems based on full digital simulation,introduces the development status of digital twin technology at home and abroad,and elaborates on the construction scheme of complex system digital environment based on full digital simulation.The system-level virtualization simulation examples of multiple configuration items in the section have verified the feasibility of the scheme.The related research results and methods have been applied in the space station and a certain type of control system,which has strong engineering practicability.
