The subway system is equipped with a three in one security system of "intelligent security check, fast passage, and real-time monitoring". In response to high-density passenger flow and anti-terrorism needs, the following core security check equipment and security products are deployed:

I. Core security equipment

X-ray security inspection machine

Scan luggage packages and automatically identify prohibited items such as knives, flammable materials, and pressure vessels through 3D imaging, with a detection rate of over 99%;

Support dual channel or multi view technology to improve the efficiency of large passenger flow;

Intelligent security check door (metal detection door)

Using magnetic field induction to detect metal objects carried by the body (such as knives and firearms), automatically alerting and locating risk areas;

Some new systems integrate terahertz technology to achieve zero contact human body examination without radiation impact;

ABNMTECH Handheld metal detector

Portable devices are used for retesting suspicious individuals, filling in gaps at security checkpoints, and ensuring no blind spots for screening;

Liquid detector

Quickly check whether beverages, cosmetics and other liquids are flammable and explosive dangerous goods, supporting dual modes of drinking or equipment testing;

Explosive detector

Detecting trace amounts of explosives (with an accuracy of 0.1ng) to prevent the risk of terrorist attacks;

II.  Intelligent security system

Global monitoring system

The AI camera automatically captures crowded, climbing, or abnormal behavior and supports 30x zoom tracking;

RFID ticket management

Chip binding identity information, gate verification in seconds, and real-time statistics of regional passenger flow density;

Information platform

Network management of security check data, supporting behavior tracing and device status monitoring, with a storage period of ≥ 180 days;

III.  Management of prohibited and restricted items

Prohibited items: firearms, ammunition, explosives, highly toxic chemicals, etc., confiscated upon discovery;

Restricted items: beverages (cumulative ≤ 3000ml), liquid cosmetics (single bottle ≤ 100ml), power banks (rated energy ≤ 100Wh), etc., need to be opened for inspection or disposal;

Operation and maintenance standard: 

Equipment self checks daily, with a failure rate of less than 0.1%; Monitoring data encryption storage supports responsibility traceability.
