Abstract
Aiming at the safety requirements of multi-RGV and multi-lift planar mobile stereo garage access vehicles, a time window-based system RGV operation blocking and deadlock control strategy is proposed. Combining the improved banker algorithm with the time window principle, the banker algorithm is used to evaluate the security of the RGV running path. If an unsafe state is detected, the RGV operation blocking and deadlock control strategy based on the time window algorithm is given. The verification is detailed through specific cases. The results show that the RGV operation blocking and deadlock control strategy proposed in this paper can improve the RGV operation efficiency while increasing the system security.
