With the rapid development of the global economy and the consistently improving living standard, there has been a growing number of vehicles. for efficient vehicle management, there has been an increasing number of parking lots and vehicle management areas beginning to use License Plate Recognition (LPR) products and Ultra-high Frequency (UHF) products. The automatic license plate identification enables fast vehicle access to parking, which provides a convenient user experience.
Automatic Vehicle Recognition (With UHF Reader and UHF Tag)
Its operation starts when a user with the passive tag drive through the UHF reader located at the entrance of the parking lot. The UHF reader will recognize the tag. The carpark barrier will lift up for access upon valid recognition. If not, access will be denied.
Automatic Number Plates Verification (With LPR Camera)
LPR technology is an application of computer video image recognition technology in the license plate identification area. Its operation starts when the vehicle is located at the entrance of the parking lot, the LPR Camera will scan on the license plate character, and its recognition technology will identify the license plate number, color, and other information. If the number on the license plate is valid, the car park barrier will lift for access, otherwise, no access will be allowed.
Dual Number Plate Authentication
(UHF and LPR Based Two-Level Authentication System for Vehicles)
Dual number plate authentication is a Multi-factor authentication to use of several authentication techniques together. Once the vehicle is located at the entrance of the carpark lot, both of the UHF reader and LPR Camera will start to recognize the UHF Tag and the number plate on the vehicle. If the verification of the number plate and the UHF tag is valid, the car park barrier will lift for access, otherwise, no access will be allowed.
Blacklist and Whitelist Management
Car Park System management Software includes Role and Black and White Lists.
If the cars are pre-set on the white list, including _re trucks, police cars, and privileged cars, they can enter and exit the parking lot free of charge. Otherwise, cars on the blacklist are not allowed to enter or exit the parking lot.
There are two kinds of UHF tags in this long-distance fixed vehicle access management application.
The UHF RFID reader is an RFID long-range proximity card reader that can simultaneously read multiple passive UHF tags at ranges up to 12m. The reader is waterproof and is suitable for use in a wide range of RFID applications, such as transport management, vehicle management, car parking, production process control, and access control.
License Plate Recognition (LPR) Camera
LPR technology is an application of computer video image recognition technology in the license plate identification area. This technology through the license plate crawling, image pre-processing, feature extraction, license plate character recognition technology to identify the license plate number, color, and other information.
