Technical Field

[0001] The present invention belongs to the technical field of parking lot management, and in particular relates to a parking lot management method and system. Background Art

[0002] With the continuous advancement of urbanization, the number of motor vehicles in cities continues to increase. Parking lots are important facilities for solving parking problems, and their utilization rate directly affects the management efficiency and utilization benefits of parking resources.

[0003] However, there are still many problems in the operation and management of traditional parking lots, especially during peak hours. Although many parking lots have a large number of vacant parking spaces, due to factors such as unreasonable parking space allocation and long time for car owners to find parking spaces, the actual parking spaces used are far lower than the theoretical utilization rate, resulting in a waste of parking resources.

[0004] At present, although some parking lots have introduced intelligent management systems, such as parking space monitoring sensors, license plate recognition systems, and navigation guidance functions, there are still some problems, such as remote parking spaces and unpredictable owner behavior, which cannot effectively improve the actual utilization rate of parking spaces. Therefore, how to improve the overall utilization efficiency of parking lots through intelligent optimization without increasing the number of parking spaces has become a technical problem to be solved.
