Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent transportation systems, and in particular relates to an intelligent parking space status monitoring system and method. Background Art

[0002] With the acceleration of urbanization and the rapid growth of the number of motor vehicles, the problem of parking difficulties has become increasingly prominent, bringing great inconvenience to people's travel. The traditional parking lot management method relies on manual inspections, which is inefficient and cannot timely and accurately grasp the parking space status information. This method is often inefficient and cannot update the usage of parking spaces in real time, making it difficult for car owners to quickly find vacant parking spaces, resulting in a waste of parking space resources and a poor user parking experience. In addition, some novice drivers are not proficient in parking skills, resulting in low parking efficiency, which will hinder other drivers passing through the channel, causing congestion. Therefore, we propose an intelligent parking space status monitoring system and method. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent parking space status monitoring system and method. Through real-time monitoring by geomagnetic sensors, pressure sensors and infrared sensors, the system can accurately determine whether the parking space is occupied, and automatically adjust the vehicle position through an electric platform, so that the driver can easily park and pick up the car, solving the problem that the traditional parking lot management method relies on manual inspections, is inefficient, and cannot timely and accurately grasp the parking space status information.
