Urban Security needs to establish a three in one prevention and control system of "intelligent security check, three-dimensional monitoring, and rapid response", and configure the following equipment and technical solutions for core requirements such as densely populated areas, prohibited item interception, and counter-terrorism and riot control:

I. Intelligent security check core equipment

Multi spectral security inspection system

Millimeter wave human body scanner enables non-contact detection of concealed items (such as ceramic knives and liquid explosives), with a resolution of millimeter level and no radiation risk;

The CT type security check machine generates three-dimensional sectional images of luggage, and AI automatically recognizes the internal structure of pressure vessels, processing ≥ 1000 items per hour;

Trace substance detection

The explosive/drug detector has an accuracy of 0.1ng and can complete particle screening in 5 seconds;

Fast pass gate

Facial recognition+RFID ticket verification, with a passage efficiency of ≤ 2 seconds per person;

II. Three dimensional prevention and control system

AI video analysis platform

4 million pixel ball machine linked with infrared fill light, automatically tracks abnormal gathering and climbing behavior, and recognizes distances of ≥ 200 meters in low light environments;

Intelligent patrol equipment

The quadruped explosion-proof robot is equipped with multispectral sensors, capable of handling suspicious objects with a load of 150kg, and has a VR remote control accuracy of 0.1mm;

Vehicle mounted mobile security check

Automatic lifting vehicle bottom scanner, capable of detecting hidden objects on the vehicle chassis in 10 seconds;

III. Emergency response configuration

Physical protective facilities

Hydraulic lifting column (anti-collision ≥ 7.5 tons)+explosion-proof tank form a two-stage interception network;

Unmanned disposal unit

The explosion-proof system of the robotic arm can remotely transfer suspicious items to the isolation area;

Global alarm network

Emergency button linkage sound and light navigation+security terminal, response delay ≤ 3 seconds;

IV. Hierarchical scenario strategy

Technical indicators of core equipment in the scene

The detection rate of CT security screening machine and millimeter wave scanner in transportation hubs is greater than 99.5%

Four legged robots and thermal imaging cameras in urban squares with environmental adaptability ranging from -30 ℃ to 60 ℃

Portable liquid meter and unmanned aerial vehicle countermeasure equipment with electromagnetic interference radius ≥ 500m in large activity areas

Key building explosion-proof wall+iris recognition gate anti explosion equivalent ≥ 1kg TNT

Operation and maintenance standards:

Monitoring data blockchain certificate storage ≥ 180 days;

Daily pressure testing of riot control equipment, with a failure rate of less than 0.05%.

Management of prohibited and restricted items

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

Restricted items: Power banks (≤ 200Wh) and tools (length ≤ 20cm) need to be opened for re inspection.

Note: The new device supports modular deployment and can dynamically adjust the security check level according to the flow density.
