Under-vehicle Safety Inspection System Software

1.Testing criteria: The equipment must undergo at least 62 tests conducted by the Ministry of Public Security Testing Center in accordance with the GA/T 1336-2016 standard, and provide a Ministry of Public Security inspection report as proof;

2.The undercarriage image is captured using a color linear array CCD scanning method.

3.Scanning method: Linear scanning, with three modes including coil triggering, video detection, and manual triggering;

4.Field of view angle: ≥178 degrees;

5.Chassis image storage format: standard BMP or JPEG image format;

6.Startup time: The total startup time for all system components should be less than 1.5 minutes.

7.The undercarriage resolution must be ≥12000×7500.

8.Environmental parameter functions: Enables display and storage of environmental parameters such as temperature, humidity, and atmospheric pressure on the software interface, with automatic upload to the server.

9.The image repository must contain at least 1.2 million vehicle under-vehicle images.

10.Speed measurement function: Measures vehicle speed as it passes through the scanner;

11.When the vehicle passes through the under-vehicle scanner at non-uniform speed or at rest, the under-vehicle image is displayed completely, and the states of vehicle motion and stoppage can be detected.

12.When the vehicle passes through the scanner at speeds of 1-80 km/h, the system's image display time shall be ≤1 second;

13.The system automatically triggers an alarm when red, green, or blue foreign objects exceeding 5cm in size appear under the vehicle.

14.The system automatically counts the number of inspected vehicles and generates a table.

15.Under-vehicle image display: Full horizontal color display with support for horizontal and vertical mirroring operations;

16.Under-vehicle image zooming feature: Minimum magnification of 16x, allowing localized image enlargement.

under-vehicle scanner

1.Induction lighting control module: four sealed single-cell LED surface light sources;

2.Field of view angle: ≥178 degrees;

3.Installation ground level height: The vertical height difference between the scanning device and the designed installation ground level shall be less than or equal to 2.5 cm.

4.The overall protection rating of the scanner complies with IP68 waterproofing requirements. The camera unit and supplementary light unit within the scanning device housing also meet the IP68 specifications outlined in GB4208-2008 (submerged at 1m depth for 1 hour).

5.Maintainability: The system scanning device should adopt a modular design, with LED fill lights and scanning cameras capable of independent disassembly, as well as easy assembly and maintenance.

6.The middle section of the vehicle under-vehicle scanning device housing can withstand stress levels of no less than 201MPa with relative deformation below 0.01.

7.The system is equipped with an induction lighting control module that automatically detects and switches the light source upon vehicle passage.

8.Operating temperature range for under-vehicle scanner: -40°C to +85°C;

9.Anti-fogging function for scanners: The under-vehicle scanner maintains operation at 40°C for 12 hours, followed by immediate cooling to 0°C for 2 hours, preventing water mist condensation inside the chamber.
