The urban public transportation system adopts a multi-tiered intelligent security solution, encompassing areas such as personnel security checks, item inspections, environmental monitoring, and emergency response. The specific application equipment is as follows:
1. Personnel security inspection and identity verification equipment
Self-service verification channel for identity and certificate matching
Integrating facial recognition and ID scanning technology to achieve contactless and rapid passage, thereby enhancing throughput efficiency during peak hours.
Millimeter-wave human body imaging security scanner
Non-contact detection of concealed metal/non-metal items (such as knives or liquids), suitable for crowded places such as subway hubs.
Handheld metal detector
Assist in the re-inspection of suspicious individuals, covering the blind spots of security checkpoints.
II. Security inspection equipment for items and vehicles
X-ray luggage scanner
Scan the internal structure of the package, and the AI algorithm automatically identifies risk items such as explosives and contraband.
Vehicle bottom scanning system
Quickly detect concealed objects on the vehicle chassis, and combine with license plate recognition technology to achieve vehicle binding and tracking.
Liquid detector and portable explosive detector
Ultra-wideband microwave technology is used to screen flammable liquids, while ion mobility spectrometry technology is employed to detect trace amounts of drugs/explosives.
III. Intelligent monitoring and early warning system
Integrated IoT Sensing Platform
Environmental sensor: It monitors temperature and humidity, air quality, and fire hazards in real time, and integrates with the ventilation system to regulate the environment.
Equipment health monitoring: Vibration sensors + temperature sensors predict track/train failures, supporting preventive maintenance.
Intelligent video analysis system
The passenger flow statistics camera automatically warns of crowd gathering risks, and the behavior analysis module identifies anomalies such as ticket evasion and trespassing.
Curve warning devices alert vehicles to the risk of intersection through LED screens and voice prompts, thereby reducing accidents.
Unmanned aerial vehicle inspection
Conduct high-altitude patrols along the track, cover fixed monitoring blind spots, and transmit real-time images of emergency scenes.
IV. Emergency protection and data security
Explosion-proof ball/explosion-proof blanket
Isolate the suspected explosive and absorb the shockwave fragments.
Electromagnetic shielding cabinet
Prevent signal interference and ensure data security of the command system.
Blockchain identity verification
Ensure the integrity and tamper-resistance of biometric data (fingerprint/iris).
Characteristics of technology integration:
Three-level response mechanism: closed-loop management is achieved through the perception layer (sensors), analysis layer (AI platform), and execution layer (emergency linkage).
"Touchless Passage Design: The walk-through security scanner allows for scanning by simply walking naturally through, optimizing the passenger flow experience.".
Data-driven decision-making: The security integration platform comprehensively schedules video, sensor, and ticketing data to generate emergency command plans.
