Design of Virtual Debugging System for Logistics Picking Based on Digital Twin

为降低调试周期和成本,提前预知系统级风险,基于数字孪生的虚实一致特性,提出一种基于数字孪生的固定轨物流拣选虚拟调试系统设计方法。根据固定轨物流拣选系统的特性和调试需求,建立虚拟物理模型、虚拟执行系统和虚拟控制系统,同时对控制器-虚拟模型接口进行设计,实现虚实之间的通信。通过物流拣选系统实例,验证了基于此数字孪生模型进行虚拟调试的有效性与实用性,基于数字孪生的固定轨物流拣选虚拟调试系统能够降低物流拣选系统的调试周期和成本,进而提高调试效率。

In order to reduce commissioning cycle and cost and predict system-level risk in advance,a design method of fixed rail logistics picking virtual commissioning system based on digital twin was proposed,which was based on the consistency of virtual and real characteristics of digital twin.According to the characteristics and commissioning requirements of fixed rail logistics picking system,the virtual physical model,virtual execution system and virtual control system were established.Then the controller-virtual model interface was designed to realize the communication between virtual and real.The effectiveness and practicability of the virtual debugging based on the digital twin model were verified by an example of logistics picking system.The virtual debugging system of fixed rail logistics picking based on digital twin can reduce the debugging cycle and cost of logistics picking system,and then improve the debugging efficiency.
