Case Study: Real-time Collision Avoidance with VC-based DT
The collision avoidance use case demonstrates the transformation of a VC model into a VC-based DT for real-time operational safety in automated production systems. By establishing direct connectivity between the DT and the Programmable Logic Controller (PLC) via a fieldbus driver, the system achieves seamless interaction and real-time state synchronization.
Leveraging the lookahead feature of the motion control system, the VC-based DT can anticipate future movements and predict potential collisions in advance. This predictive capability, coupled with high model accuracy, enables the system to autonomously stop robots before physical contact, thereby preventing operational disruptions and ensuring safety.
This implementation confirms the technical feasibility of integrating high-fidelity VC models into the operational phase, delivering tangible benefits by visualizing predicted movements and proactively avoiding hazards. It serves as a strong example of how existing engineering assets can be repurposed to create powerful, production-supportive Digital Twins.
