Design of Virtual Intelligent Parking Lot System Based on Signal Request Mechanism

The virtual AGV fully automatic parking system is theoretically researched based on the parking management problems of traditional parking lots such as shortage of parking spaces, poor service quality, and low satisfaction. In this paper, a virtual intelligent parking system based on the signal request mechanism is designed. In theoretical research, corresponding solutions are proposed for the selection of parking spaces, the path planning of the parking AGV and the deadlock processing of the AGV. The selection mechanism of free parking spaces is based on the principle of proximity, path planning is based on Dijkstra's algorithm, and the deadlock conflict resolution method is based on the signal request mechaLnism. The core part is the deadlock conflict processing of intersection nodes. Based on the original priority of transportation tasks, this paper takes into consideration factors such as remaining distance, transportation type, waiting time, time peaks. This paper introduces a new type of dynamic priority which effectively improves the efficiency of solving the backlog of parking AGV caused by deadlock conflicts.
