Metro stations need to build an intelligent security system that integrates "inspection of objects, inspection of personnel, and informatization". The core configuration is as follows:
I. Intelligent security inspection equipment combination
Dual channel multi view X-ray machine
The upper and lower dual channel design improves packaging efficiency by 50%, with dual source imaging penetration of ≥ 50mm steel plate. AI automatically labels explosive structures, lithium batteries, and liquid hazardous materials, with a false alarm rate of ≤ 0.3%;
Differentiated personnel security check system
The 18 location intelligent security checkpoint realizes millimeter level positioning of knives/firearms (error ≤ 5cm), integrates facial recognition and temperature monitoring modules, and activates fast lanes or key inspections according to passenger risk levels;
Auxiliary detection equipment group
Handheld metal detector (sensitivity 0.1g) assists in re inspection, vehicle bottom scanning mirror checks for foreign objects on the vehicle chassis, and shoe metal detector blocks concealed carrying.
II. Global intelligent security platform
（1） Video surveillance center
Infrared high-speed ball camera: automatic supplementary lighting in low light environments, 85x zoom coverage of station halls/platforms, smoke and fire recognition response ≤ 2 seconds;
Behavior analysis system: AI automatically identifies 23 types of abnormal behaviors such as jumping gates and reverse escalators.
（2） Multi system linkage control
Security integration platform: seamless integration of video, access control, perimeter alarm and other subsystems, event linkage response ≤ 3 seconds;
Security check information management: Real time monitoring of the number of packages passed by X-ray machines, interception rate of prohibited items, and automatic warning of equipment failures.
III. Key Area Protection Plan
Key points of regional equipment configuration technology
Entrance and exit gate facial recognition gate+anti tailgating alarm real name verification+abnormal passage interception
Intelligent distribution cabinet in equipment room+explosion-proof wall (0.25mmpb lead plate) radiation shielding+temperature and humidity linkage
Perimeter protection vibration fiber+pulse electronic fence linkage video pop-up positioning
IV. Efficiency optimization technology
Graded security inspection strategy
Frequent travelers activate the fast lane through facial recognition, reducing the sampling rate to 10% and increasing the travel speed by three times during peak hours;
Centralized image judgment center
Remote expert review of suspicious luggage images has improved the accuracy of image recognition to 99.2%;
Emergency explosion-proof unit
Explosion proof tanks (capable of withstanding 3kg TNT equivalent) are deployed in the ticketing center, and explosive disposal robotic arms remotely handle suspicious objects.
Industry trend: Leading manufacturers such as NUCTECH and Shengxun Electronics are promoting the popularization of CT security inspection machines and achieving three-dimensional structure reconstruction of explosives; Honeywell and other platform providers deepen the integration of AIoT and build a "seamless" ecosystem.
