Design principles 

Maintainability: Maintainability is an important factor in ensuring the normal use of a system. Maintainability has two layers of meaning: a. It is easy to troubleshoot faults; b. Easy daily management and operation. 

Reliability: It is necessary to consider the use of mature technology and products, with the principle of "stability over everything", to ensure overall stability in equipment selection and system matching. 

Economy: Considering the overall cost of the parking lot system and its long investment return period, the cost of the entire system should be controlled as much as possible while meeting performance requirements. 

Progressiveness: The system adopts advanced technology and equipment, which reflects the advanced level of the system on the one hand, and ensures that the system has a long life cycle on the other hand. 

Scalability: This system considers future development needs and must ensure compatibility with system expansion. 

Practicality: When designing this system, consideration should be given to meeting the functional requirements and practical application needs of the parking lot, while also considering the convenience and safety of drivers entering and exiting. 

Holistic: The holistic nature of a system, involving all aspects. For projects like the system, these factors must be comprehensively considered to form an organic comprehensive management system. 

Security: Effective high-tech measures must be taken to prevent theft of vehicles on site to the greatest extent possible; At the same time, the system must be standardized in terms of fee design.

Overview of License Plate Recognition 

License Plate Recognition (LPR) technology is based on computer technology, image processing technology, and fuzzy recognition to establish a vehicle's feature model and recognize vehicle features, such as license plate, model, color, etc. It is a specialized computer vision system that focuses on specific targets. It can automatically extract license plate images from an image, segment characters, and recognize characters. It uses advanced image processing, pattern recognition, and artificial intelligence technology to process the collected image information. It can automatically recognize the numbers, letters, and Chinese characters of license plates in real time and accurately, and directly provide recognition results, making computerized monitoring and management of vehicles a reality.

System composition structure diagram:

Entrance equipment 

One set of license plate recognition display screen all-in-one machine, one set of barrier gate, and two sets of vehicle detectors, to achieve active recognition and verification of license plates by the system when the vehicle arrives, and to reasonably block or release the vehicle in combination with the barrier gate; 

Management position 

A set of industrial control integrated license plate recognition/billing/management host, which can achieve equipment management, license plate recognition, parking billing, data processing and other functions;

Export equipment 

One set of license plate recognition display screen all-in-one machine, one set of barrier gate, and two sets of vehicle detectors, which enable the system to actively recognize license plates and charge when the vehicle arrives, and combine with the barrier gate to reasonably block or release the vehicle; 

Management Center 

One data storage server to achieve data management, storage, and sharing
