The Public Transportation Network needs to establish a security system that emphasizes both efficient traffic and precise prevention and control, combined with intelligent recognition and rapid response technology. The core security equipment and security products are configured as follows:

I. Intelligent security inspection equipment

Channel type X-ray security inspection machine

Dual energy imaging technology, penetrating steel plates with a strength of ≥ 34mm, supporting automatic labeling of foreign objects in luggage (tools/lithium batteries/liquid bombs, etc.), with a passage efficiency of ≥ 1000 pieces/hour;

Intelligent security checkpoint

Six zone metal detection, sensitivity graded adjustment (can shield keys and other household metals), with a travel speed of 40 people/minute;

Handheld auxiliary equipment group

Portable metal detector (positioning accuracy ± 5cm)+liquid security detector (microwave technology can identify flammable liquids in 3 seconds);

II. Special testing for prohibited items

Technical characteristics of equipment type detection capability

Trace explosive detector Raman spectroscopy technology, with a detection limit of Pic level, completes explosive/drug particle analysis in 30 seconds

Radioactive material monitoring door gamma/neutron dual-mode detection, uranium-235 detection limit of 1 μ Ci, sound and light alarm+GPS positioning linkage

Vehicle bottom scanning robot multispectral imaging, identifying illegal modifications and attachments on the chassis with a scanning accuracy of ± 2mm

III. Stereoscopic protection system

Perimeter intelligent monitoring

Thermal imaging ball machine (detection distance ≥ 1.2km)+distributed fiber optic vibration sensor (intrusion positioning error<50 meters);

Anti drone system

Directional radio frequency interference (1.5GHz-5.8GHz)+GNSS deception, suppression radius of 3 kilometers;

Emergency interception facilities

Hydraulic lifting and blocking pile (resistant to 15 tons of impact)+explosion-proof tank (resistant to 8kg TNT equivalent);

IV. Data and Operations Center

Centralized image recognition platform

AI assisted labeling of hazardous material structures reduces misjudgment rate by 40% and supports remote expert review;

Multi system linkage control

Integrated X-ray machine, gate, monitoring data, event response ≤ 3 seconds;

Emergency evacuation system

Sound and light guided broadcasting (sound pressure level ≥ 90dB)+screen dynamic escape route push;
