technical field

The invention relates to the technical field of the Internet of Things, in particular to a management system and method for an intelligent parking lot.

Background technique

The parking lot intelligent management system is a general term for the modern parking lot vehicle charging and equipment automation management. It is a high-tech mechatronics product that completely puts the parking lot under the unified management of the computer. The whole system takes IC card or ID card as the carrier, through intelligent equipment, the induction card records the relevant information of vehicles and cardholders entering and leaving, and at the same time calculates and transmits the information, and converts it into manual through human-machine interface such as character display and voice broadcast. Signals that can be identified and judged, so as to achieve the purpose of time charging, vehicle management, and intelligent vehicle guidance. The system is an organic combination of mechanical, electronic computer and automatic control equipment and smart IC card technology, which can realize vehicle image comparison, automatic charging, automatic data storage and other functions under computer management.

The existing parking lot charging methods are mainly divided into the following two ways. The first method is to issue an IC card. When the vehicle enters the parking lot, a parking IC card is obtained, and the vehicle exits the parking lot. On the access control system Identify the card, then record the parking time of the vehicle in the parking lot, and charge for parking. However, there are many drawbacks in this method of realizing parking charges through parking cards. Every time you enter and exit the parking lot, you need to get the parking card and return the parking card. The charging procedure is more complicated, especially when entering the parking lot and driving out of the parking lot. During the prime time, the need to park to pick up and return the card will lead to queues of vehicles. Another way is to set up fences at the entrance and exit of the parking lot, a high-definition camera that can capture vehicle license plate number information, and an identification device that can extract the license plate number. When the car enters the parking lot, when the car leaves the parking lot, it also needs to collect the license plate number information of the vehicle and the time of driving out through the camera, and calculate the amount of parking fee that needs to be paid by comparing the driving time and driving time, and then drive Pay at the exit. After the payment is successful, the fence will rise and the car will leave the parking lot. Compared with the IC card form, the management efficiency will be higher, and the queue of vehicles will be reduced, but the payment of the parking fee is still It is unified at the exit of the parking lot. Cars driving out of the parking lot need to park at the exit and pay the parking fee. During the golden hours of entering and exiting the parking lot, there will still be queues.
