A single computer can simultaneously capture and identify channels 2, 4, 8, and 12 in real-time. We provide detailed customized development for different project requirements.

This system is developed using a license plate recognition system, which combines computer vision technology, neural network system technology, mechanical and electronic automation equipment, computers, and smart card technology to effectively manage various types of vehicles entering and exiting. Determine whether the vehicle is inside by the license plate number, and the barrier will automatically open. External vehicles entering require manual confirmation. Blacklist comparison, prompt alarm, and vehicle flow statistics function. Adopting stable and reliable large-scale database software Microsoft SQL Server 2000. Unified operation interface, full online help, and strong compatibility. Automatic license plate recognition, real-time monitoring, and reporting.

system description

Vehicle entry

The vehicle enters the license plate camera capture area and triggers the ground sensing coil.

The license plate recognition system automatically captures the image of the vehicle and identifies the license plate identification number, and then retrieves the vehicle category through a database search.

Determine whether there is an internal vehicle based on license plate number data, and achieve automatic opening of the barrier. Foreign vehicles require manual confirmation. Blacklist comparison is correct.

Release the gate and record the vehicle's entry time. The entire process is completed automatically without the need for staff intervention. The vehicle has been in motion and has been continuously paused.

Vehicle departure

The vehicle enters the license plate camera capture area and triggers the ground sensing coil.

The license plate recognition system automatically captures the image of the vehicle and identifies the license plate identification number, and then retrieves the vehicle category through a database search.

If the vehicle belongs to an internal vehicle situation, the gate will automatically start and release. The computer retrieves the captured image of the car entering the venue, the entry time, etc

If the vehicle is blacklisted, whether it is a temporary or fixed vehicle, the gate will not be opened, and the system will issue an alarm signal to notify the staff to pay attention.

The vehicle crosses the entrance and exit, enters and leaves the parking lot, and the system records the departure time of the vehicle.
