Integrated Main Scanning Unit

Combines a high-resolution line-scan camera, auxiliary LED illumination, a protective lens cover, and a rugged, weather-resistant enclosure for long-term outdoor operation.

Automatic Number Plate Recognition (ANPR) Camera

Performs real-time license plate capture and database logging for entry/exit traffic, automatically transmitting records and vehicle metadata to the central software interface.

All-in-One Integrated Control Cabinet

Consolidates system power distribution, intelligent logic controllers, and automated thermal control systems into a single centralized cabinet for operational stability.

Industrial-Grade Embedded Control Software

Pre-configured with a hardened, multi-platform Linux/Windows enterprise architecture. Delivers plug-and-play under-vehicle scanning, real-time license plate recognition (ANPR), and seamless integration with localized security management networks

The YD-GUVSS-G Fixed Under Vehicle Scanning System (UVSS) is a commercial-grade security screening solution designed for permanent installation at high-security access control points. Utilizing advanced 4096-pixel linear array CMOS technology and 400W sealed LED auxiliary lighting, this system delivers instant, full-width undercarriage images at resolutions over 90 Megapixels as vehicles pass through at speeds up to 120 km/h.

Engineered with a 50-ton load-bearing capacity and IP68 dual-waterproof sealing, the YD-GUVSS-G performs reliably under heavy truck traffic and extreme outdoor environments. The system features integrated 2-channel Automatic License Plate Recognition (ANPR), optional AI-powered suspicious object identification, and dynamic historical image comparison. With built-in environment monitoring, anti-fog air circulation, and a capacity to store over 1,000,000 inspection records, the YD-GUVSS-G provides security screening for government sites, prisons, border checkpoints, and critical infrastructure.

Core Features & Technical Advantages

4096-Pixel Line Array Scanning Technology

Produces seamless, high-definition underbody scans at 90+ Megapixels with zero perspective distortion, capturing minute details such as attached explosive devices or concealed compartments.

AI Contraband Detection & Dual-Screen Comparison (Optional)

AI algorithms automatically flag suspicious objects (tools, weapons, altered wiring) while instantly displaying current undercarriage images alongside historical scans tied to the same license plate.

50-Ton Load Capacity with Vibration Relief

Constructed with high-strength structural alloys and vibration-absorbing bottom-troughs, allowing continuous transit of fully loaded cargo trucks and armored vehicles.

2-Channel ANPR & Blacklist/Whitelist Management

Includes dual license plate recognition channels (95%+ whole-plate accuracy, <20ms processing time) with automated gate release for whitelisted vehicles and instant alerts for blacklisted plates.

IP68 Sealing & Anti-Fog Air Drying System

Built with military-grade dual-layer seals and internal heating/air drying mechanisms to prevent lens condensation, ensuring clear imaging in rain, snow, and extreme humidity (-20°C to +60°C).

Frequently Asked Questions

Q1: How does the AI comparison function work on the YD-GUVSS-G?

A: When a vehicle passes over the scanner, the ANPR camera reads its license plate and retrieves previous scans from the 1,000,000-record database. The system displays the historical image alongside the live scan on a split screen, while AI algorithms automatically highlight suspicious structural differences or added objects. (AI module optional)

Q2: Can the YD-GUVSS-G handle heavy commercial trucks?

A: Yes. The scanner module is enclosed in a high-strength, pressure-resistant steel trough designed for axle loads exceeding 50 tons, making it suitable for fully loaded cargo trucks, container transports, and buses.

Q3: How does the system prevent optical fogging in winter or rain?

A: The scanner housing features an integrated air-drying circulation system and temperature/humidity sensors that automatically clear internal condensation and lens fogging, maintaining clear image capture year-round.
