Smart city parking lot parking space prediction method and system based on Internet of Things

The invention relates to the field of data processing, in particular to a smart city parking lot parking stall prediction method and system based on the Internet of Things, and aims to solve the problems that an existing smart parking management system based on the Internet of Things cannot predict parking stalls in pre-selected parking lots, cannot intelligently reselect congested parking lots, and cannot predict parking stalls in the pre-selected parking lots. The problems that the parking spaces of the pre-selected parking lot are fully parked and are jammed at the entrance of the parking lot, traffic jam is caused, and the parking efficiency of the user cannot be guaranteed are solved. According to the parking lot parking space prediction method, the parking spaces in the parking lot can be predicted, and the prediction condition of the parking lot can be checked anytime and anywhere, so that timely scheduling and management can be carried out, the congested parking lot can be intelligently reselected, th
