Research And Implementation Of Intelligent Parking System Based On AGV

With the increasing difficulty of parking in cities,various solutions have emerged,and the research and application of AGV(Automatic Guided Vehicle)intelligent parking garages have gradually developed.The parking AGV is applied to the smart parking system,which can be used for automatic access to vehicles,which can save parking space while improving parking efficiency,thereby alleviating the difficulty of parking in static traffic.In the AGV-based smart parking system,reasonable path planning and real-time task scheduling can ensure the system’s performance and efficiency.Therefore,this paper focuses on parking AGV operation guidance,parking system path planning,access vehicle task scheduling and system Design and preliminary implementation of four aspects for systematic research.Aiming at the problem of parking AGV operation guidance,this paper introduces a road marking line visual detection method.First preprocess the image,then use Canny operator to detect the edge,and finally use the Hough transform method to detect the center line.Experiments show that this method is very robust.Aiming at the path planning problem of parking AGV system,this paper firstly proposes an improved artificial fish school algorithm,improves the foraging behavior by introducing the target-oriented factor,and then designs the optimal solution selection method,and selects the shortest running time among the feasible solutions.Then,an improved conflict scheduling strategy is proposed,and the path information is dynamically operated according to the multi-states after the AGV joins the system.Experiments show that the improved method can effectively improve the efficiency of coordinated operation of multiple AGVs.Aiming at the problem of multi-task scheduling in parking system,this paper proposes an improved task scheduling method based on priority level.First,the task priority is calculated according to the priority level,the tasks are sorted,and then the AGV with the shortest waiting time is selected to execute the scheduled tasks.Experiments show that the improved method has good effects in terms of the degree of system task delay and completion time.Based on the above research work,this paper designs and implements an AGV-based smart parking system.The system initially implements multi-parking AGV path planning and task scheduling functions.
