“Mobile phone + card-free convenient access” Passage detection terminal
This terminal adopts an integrated design and is primarily composed of the following five core units, aiming to achieve high reliability, high precision, and high efficiency in comprehensive vehicle information perception and processing:
(1) Capture triggering unit: The high-performance domestic millimeter-wave radar utilizes a self-developed high-performance millimeter-wave radar as the main triggering and core motion perception unit. This radar exhibits excellent anti-interference and environmental adaptability,
Unaffected by rain, snow, fog, strong light, and nighttime illumination, it achieves stable operation around the clock, providing accurate and reliable vehicle arrival trigger signals for the system;
(2) License plate and feature capture unit: The dual-camera stereo synchronous capture system adopts a dual-camera stereo layout, achieving synchronous capture with dual cameras through precise triggering by millimeter-wave radar. This design enables capture from multiple angles
Capture high-definition images of vehicles, significantly enhance the license plate recognition rate in complex scenes, and simultaneously capture detailed features such as vehicle type, color, and brand;
(3) Speed monitoring unit: radar-based synchronous and precise speed measurement. The built-in millimeter-wave radar directly measures the real-time speed of vehicles based on the Doppler effect while completing triggering. It features high speed measurement accuracy, fast response, and objective and reliable data
Damn. This function not only supports traffic flow monitoring and analysis, but also provides effective technical means for electronic police applications such as speeding violation monitoring;
(4) Vehicle feature processing unit: Edge intelligence fusion processing is equipped with a high-performance edge computing unit (MEC) for local fusion processing of millimeter-wave radar data and dual-camera image data. Through AI algorithms,
Real-time completion of comprehensive analysis such as license plate recognition, vehicle feature extraction, and speed matching, achieving “perception as analysis”;
(5) The integrated structure and standardized interface adopt an industrial-grade integrated design, highly integrating the aforementioned units within a protective enclosure, resulting in a compact structure with strong environmental adaptability. This design simplifies the on-site installation process and reduces costs
Construction and maintenance costs. The terminal provides unified power supply, network, and data communication interfaces externally, supporting standardized access, greatly reducing on-site configuration and debugging workload, and facilitating rapid system deployment and scalability

License plate number recognition:
The system strictly adheres to relevant standards such as the national GA/T 833-2016 "Technical Specification for Automatic Recognition of Motor Vehicle License Plate Images", and supports the recognition of all types of license plates, including blue plates, yellow plates, green plates (new energy vehicles), white plates (police and military), black plates (for entry and exit from Hong Kong and Macao), and trailer plates. It accurately distinguishes the color of license plates, achieving a comprehensive recognition rate of over 99% in typical scenarios;
License plate number recognition:
Based on the stereo vision of dual cameras and AI vision algorithms, the system can simultaneously extract multi-dimensional feature information of passing vehicles, including but not limited to:
Vehicle attributes: brand, model, year, vehicle type (such as sedan, SUV, truck, etc.);
Appearance characteristics: body color, cabin structure (flatbed, stake body, van body, etc.), vehicle length classification;
Special identification: whether the vehicle is carrying hazardous chemicals, whether it is covered with a tarpaulin, whether there is abnormal loading, etc;
Vehicle speed detection:
Relying on millimeter-wave radar direct speed measurement technology, the system can achieve real-time and accurate vehicle speed monitoring, with a speed measurement error of ≤±2%, and comprehensive performance within the standard speed measurement range
The detection accuracy is not lower than 99%, and it supports the output of evidence chain for traffic law enforcement;
Vehicle traffic statistics:
The system possesses a precise vehicle classification and statistics function, capable of automatically distinguishing between various categories such as small passenger cars, small trucks, medium and large trucks, buses, container trucks, and hazardous chemical vehicles. It achieves lane-level and time-period-level traffic flow statistics and report generation, supporting traffic situation analysis and control decision-making;
Internet Disconnection Resume Function:
The system incorporates a built-in local storage and communication link detection mechanism, which automatically triggers data caching and resuming strategies in case of network interruptions. It supports resume from a broken point and data counting
Based on integrity verification, we ensure "zero loss" of critical access data, which will be automatically synchronized to the central platform upon network recovery.
