摘　　要：针对PLC和ABB工业机器人联合控制的生产系统现场调试成本高、仿真平台难以驱动机器人仿真等问题,以电机基座码垛线为研究对象,提出一种基于仿真平台NX MCD的电机基座码垛线虚拟调试方法。首先,基于数字孪生技术在NX MCD中构建产线的仿真模型;其次,设计虚拟调试方案的通信框架,主要利用C#语言并基于PC SDK对机器人仿真器进行二次开发以实现对机器人的控制和数据读取;最后,利用OPC UA技术完成PLC控制、机器人控制和NX MCD模型之间信号和数据的实时传输和反馈,完成产线联合调试。仿真结果表明:基于NX MCD的电机基座码垛线虚拟调试方案可行,能及时规避产线缺陷,缩短调试周期,降低开发成本。A virtual debugging method for motor base palletizing line based on simulation platform NX MCD was proposed to address the high cost of on-site debugging of production systems jointly controlled by PLC and ABB industrial robots,as well as the difficulty of driving robot simulations on simulation platforms.A simulation model of the production line was constructed in NX MCD based on digital twin technology.A communication framework for virtual debugging solutions was designed,mainly including secondary development of robot simulators to achieve control and data reading of robots.Finally,the real-time transmission and feedback of signals and data between PLC control,robot control,and NX MCD model were completed using OPC UA technology to complete the joint debugging of the production line.The simulation results show that the virtual debugging scheme for the motor base stacking line based on NX MCD is feasible,can timely avoid production line defects,shorten debugging cycles,and reduce development costs.
