The entrance and exit management system has become an extremely important part of the security system. In some developed countries, it is developing at a higher rate than other security products, and is widely used in office buildings, campuses, government agencies, industrial parks, various venues, etc. Management aspects of various channels. The entrance and exit management system mainly includes two categories: access control and license plate recognition parking lot management. So far, the parking lot management system has been widely used in large, medium and small cities across the country. Technology has also been greatly developed, identification from simple paper tickets, ID cards, to long-distance smart cards and other methods.
In recent years, the license plate recognition technology, which has been mainly used in expressway vehicle management, has been applied to the entrance and exit control system, providing a new solution for the intelligent management of parking lots.
The following is a brief introduction to the implementation process of the system:
First, when the monthly card vehicle enters, the license plate camera captures the image, the system automatically recognizes the license plate number, license plate color, automatically determines the vehicle type, etc., and records the information such as the entry time of the vehicle in the database, and then determines whether the vehicle is a monthly card vehicle or a temporary vehicle. , if the monthly card vehicle system is automatically released, there is no need to manually control the switch of the barrier; when a temporary vehicle enters, the system will time the time, and automatically enter the admission information into the database, issue an alarm, and require manual intervention to release;
Second, in the exit part, when the vehicle arrives at the exit recognition area of the parking lot, the camera automatically identifies the vehicle license plate number, vehicle color and enters the exit information, and then makes a judgment on the vehicle type. If it is an internal car, the system will directly lift the gate to release or release it after confirmation according to user settings or property management requirements; if it is a temporary vehicle, the parking fee receivable will be determined according to the vehicle type and parking time charging standard.
