摘要: 为了解决生产线的设计调试周期长、成本高等问题,研究了制造系统的调试方法及其应用。根据各方法的特点,集成软件在环、硬件在环和设备在环技术,提出一种基于数字孪生的生产线分布式近物理集成调试方法。该方法通过在设计阶段搭建物理实体的数字孪生模型,能够对生产线进行设计方案的虚拟调试、控制器的半实物调试和虚实同步的设备在环调试,支持多供应商设备异地分段式的空载集成调试,以改善智能车间生产线集成过程中对异地设备和整线管控逻辑的调试验证过程。最后基于数字孪生系统 (digital twins system, DTS) 并通过电机装配线案例验证了该方法的有效性。

Abstract: In order to solve the problem of long cycle and high cost of production line designing and commissioning, the commissioning method and its application in manufacturing systems are studied. According to the characteristics of each method, a digital twins-based distributed approximate physical integrated commissioning method for production lines is proposed by integrating hardware-in-loop, software-in-loop and equipment-in-loop technology. Through establishing digital twins model for physical entities during the design phase, this method can conduct commissioning of production lines with virtual commissioning for the design scheme, semi-physical commissioning for the controller and equipment-in-loop commissioning for the synchronization of virtuality and reality. Also, it supports sectional no-load integrated commissioning for multiple suppliers' equipment to improve the commissioning and validation processes of remote equipment and production line control logic during the integration process of intelligent workshop production lines. Finally, the effectiveness of the method is verified based on a digital twins system (DTS) through a case of a motor assembly line.

Key words: digital twins, distributed, approximate physical simulation, integrated commissioning
