Traditional truck scale weighing system: there are two ways. One is to manually enter the license plate, which requires a long time to wait and increases the cost of labor, The electronic weighbridge features and is prone to errors, even cheating and other related problems; The other is to use IC card swiping. Although it is also called unattended weighing system, it increases the cost of the card. The parameters of the electronic weighbridge are also easy to be damaged and lost, and cheating may also occur. It is not a fixed vehicle scenario, and it also needs to go to the site to get the card, which is inefficient and increases the time.
Application of License Plate Recognition in Unattended Truck Scale Weighing System
The unattended truck scale weighing system is a system related to vehicle weighing, such as entrance and exit management, over limit and violation management, truck scale weighing management, etc, Electronic weighbridge manufacturer It is required to record the license plate number and identify the license plate while measuring the vehicle load, and establish the corresponding relationship. License plate recognition camera combined with weighing system can also be widely used in highway overload detection station, electronic weighbridge size high-speed dynamic weighing, mine gate, source enterprise overrun control, weighing payment and other fields.
The unattended truck scale weighing system is generally composed of intelligent license plate recognition camera, weighing detection equipment, data collector, LAN equipment, management host and other related equipment.
The intelligent license plate recognition applied in the unattended truck scale weighing system has obvious advantages, as follows:
1. The product structure design is beautiful and adopts domestic professional manufacturing technology;
2. The product quality is hard enough, and all the components used meet the national standards;
3. It is highly integrated with 2.8-12mm automatic zoom lens (with fixed focus option), IP66 metal protective cover, imported LED flash fill light, nano lens protective glass, etc;
4. Unique advantages of OCR core algorithm;
5. The comprehensive recognition rate is 99.7%, and the night recognition rate is 98%;
6. Fast recognition speed, 2000 characters/second;
7. Provide richer interfaces and functions, and support Windows/Linux operating system;
8. The large angle recognition rate can still be maintained at more than 90%, and can freely deal with various installation scenarios;
9. The recognition and processing capability of abnormal license plates is extremely strong, and the recognition rate of exposed, stained, shaded and other license plates can still be maintained at more than 90%;
10. The most complete license plate types are: ordinary blue plate, yellow plate (single and double deck), military plate, police plate, armed police plate, civil aviation plate, agricultural plate, embassy plate, consulate plate, Hong Kong and Macao exit and entry plate, etc.
