The transportation system needs to establish a three in one security system of "intelligent security check, three-dimensional prevention and control, and rapid response", and configure the following equipment and technical solutions for core needs such as large passenger flow, prohibited item interception, and counter-terrorism and riot control:

I. Intelligent security check core equipment

Dual channel X-ray security inspection machine

Using 3D imaging technology to automatically identify cutting tools, flammable liquids, and pressure vessels, with a detection rate of over 99%, processing 800 pieces of luggage per hour;

Support dual view scanning to improve the efficiency of large luggage detection, suitable for high traffic scenarios such as airports and high-speed railway stations;

Terahertz human body security scanner

Zero contact scanning detects metal/non-metal prohibited items (such as ceramic knives and explosives) hidden inside clothing, with no ionizing radiation safety risks;

Trace explosive detector

Precision up to 0.1ng, quickly screen for residual particles of explosives on the surface of luggage;

II. Three dimensional prevention and control system

AI video surveillance platform

The 2-megapixel ball camera automatically captures abnormal behaviors such as trampling, climbing, and staying, and supports 30x optical zoom to track targets;

Deep learning methods are used to identify risks such as abnormal opening and closing of platform screen doors and falls on escalators, with a response delay of ≤ 2 seconds;

Intelligent Ticket Management System

RFID chip binding identity information, gate verification of passage permissions in seconds, triggering diversion warning for excessive passenger flow;

Vehicle security check unit

The automatic vehicle bottom scanning system is used to detect hidden dangerous objects on the vehicle chassis, and explosive detection dogs are added to strengthen inspections in key areas;

III. Emergency Response Configuration

Physical blocking facilities

Hydraulic lifting column+anti-collision guardrail intercepts vehicle attacks, with an impact resistance capacity of ≥ 7.5 tons;

Unmanned disposal equipment

A quadruped robotic dog carrying an explosion-proof canister enters a dangerous area to dispose of suspicious objects;

One click alarm device

Deploy emergency buttons on the platform/carriage, coordinate with the broadcasting system to evacuate the crowd and locate the incident site;

IV. Hierarchical scenario strategy

Technical indicators of scene core equipment combination

The detection rate of airport/high-speed rail security check dual view X-ray machine+terahertz security check instrument is greater than 99%

Subway gate channel facial recognition gate+liquid detector passage time ≤ 3 seconds/person

Large scale dual view X-ray machine (ABNM-150150DV) for logistics transfer station with penetration power greater than 34mm steel plate

Portable security checkpoint at bus hub+handheld metal detector with magnetic induction intensity ≤ 30 μ T

Operation and maintenance standards:

Monitoring data encrypted storage for ≥ 180 days supports behavior backtracking;

Explosion proof equipment undergoes daily self inspection, with a failure rate of less than 0.1%.

Management of prohibited and restricted items

Prohibited items: seven categories including firearms, ammunition, explosives, and highly toxic chemicals;

Restricted items: Power banks (≤ 100Wh) and liquids (single bottle ≤ 100ml) need to be opened for inspection.
