1. System overview
With the development of society and economy, the number of cars has increased sharply, and the requirements for parking lot, toll management, and safety management are also increasing. The use of electronic information technology to achieve safe and efficient intelligent management has become the main development direction of vehicle management. In the conventional vehicle entry and exit management system, people use non-contact sensing technology, and the sensing distance ranges from 5CM to 8M. The non-contact card is used as the most important identification mark of the car’s identity. Although it can be achieved without stopping, it is In order to ensure the unification of the card and the car, it is usually necessary to add an image comparison system, that is, when the car is leaving, the person on duty will manually compare the incoming and outgoing images of the car to ensure the accuracy and safety of the card and the car. Time-consuming and laborious, there may be congestion problems when vehicles enter and exit peaks, and it cannot solve the human factors existing in vehicle entry and exit management. The introduction and application of license plate recognition technology has effectively solved the problem of identification in the vehicle management system. Although the license plate has a variety of characters, colors, format content and production materials, the car license plate number is still the most accurate and specific in the world The only "ID card" identification of the vehicle, the automatic license plate recognition technology can realize the automatic registration and verification of the car's "identity" without any changes to the car.

1. Entry and exit management
The entrance and exit management system is mainly used to control the entry and exit of vehicles by adopting the combination of electric car blocker + license plate recognition module equipment, and integrating the equipment. Combined with controlling the number of vacant parking spaces, calculating or limiting parking time, strengthening the anti-theft/anti-cheating function, the system can more effectively identify and manage vehicles entering and exiting the field.
Entry and exit structure
Vehicle approach process
When the vehicle enters the field, it uses video detection, triggers the radar or trigger coil, triggers the capture machine, takes the license plate image, obtains the license plate number from the image through the license plate recognition system, and enters this number into the database for comparison. If it is a temporary user vehicle, store the acquired vehicle information and entry time into the system database and lift the rod to release. If it is a fixed user vehicle, verify that the information is correct, store the entry time in the system database and lift the bar to release. If the information verification fails or the fixed parking has expired, it will be transferred to manual operation renewal or temporary user vehicle management. In addition, if there is no more space in the venue, the message "Parking space is full" will be displayed on the information display screen at the entrance and exit to guide the vehicle to leave.
When the vehicle enters the field, the vehicle information, parking information, welcome message, etc. will be voice broadcast and displayed on the information display screen.
Vehicle approach flow chart
When the vehicle is out of the field, vehicle information, parking information, charging information, etc. will be broadcast and displayed on the information display screen.
