| 为实现制造业自动化生产线的优化运营,设计了基于Unity的数字孪生平台。首先,利用SolidWorks软件进行三维建模,在Unity平台中按与物理生产线1：1的尺寸比例完成虚拟自动化生产线的搭建;其次,在Unity平台中建立工业机器人数学模型,利用D-H参数表,进行正、逆运动学求解,实现对工业机器人的运动控制;最后,基于Snap7协议实现西门子PLC与Unity平台的数据交互。结果表明,通过数字孪生平台,可以实现生产线全流程的可视化,从而能够更好地了解生产线的运行状态,及时发现问题和解决问题。 |

| In order to optimize the operation of the automated production line in manufacturing industry, a digital twin platform based on Unity is designed. First,the SolidWorks software is used to complete 3D modeling,where the virtual automated production line is constructed on the Unity platform, 1:1 ratio with the physical production line. Then,the mathematical model of an industrial robot is established on the Unity platform. With its D-H parameter table, the forward and inverse kinematics are derived to realize the motion control of the robot. Finally,the data exchange between Siemens PLC and Unity platform is realized based on Snap7 protocol. The results show that the digital twin platform can visualize the whole process of the production line, which can help us better know its operation status, so as to find and solve the problems timely. |
