The Public Security Bureaus need to build a full chain security system of "intelligent recognition+precise prevention and control+emergency response", with the following core configurations:
I. Intelligent security inspection equipment system
Multi band security checkpoint
8-zone electromagnetic induction technology, supporting millimeter level positioning of cutting tools/firearms (error ≤ 5cm), adjustable sensitivity to shield against daily metal interference such as keys, with a passage efficiency of ≥ 35 people/minute;
X-ray security inspection machine
Dual view imaging penetration of steel plate ≥ 32mm, intelligent recognition of explosive structure, drugs and liquid dangerous goods, classification display of organic matter (orange) and inorganic matter (blue), detection of ≥ 720 pieces per hour;
Trace substance detection group
Portable Raman spectrometer completes explosive/drug particle detection in 30 seconds (detection limit Pic level), handheld liquid detector identifies flammable and explosive liquids in 3 seconds;
II. Global security monitoring platform
（1） Intelligent Video Hub
Infrared high-speed ball camera: 85x zoom coverage for reception/case handling areas, automatic fill light in low light environments, supporting face capture and 23 types of abnormal behavior recognition;
Distributed storage system: NVR devices store video recordings for at least 90 days and support precise positioning of alarm points on electronic maps;
（2） Multi system linkage control
Emergency command platform: integrating video surveillance, access control, perimeter alarm and other subsystems, with event response delay ≤ 3 seconds;
Drone countermeasure system: directional radio frequency interference (1.5GHz-5.8GHz)+GNSS deception, suppression radius of 3 kilometers;
III. Special scenario protection plan
Key technical points of regional key equipment
Anti collision soft package wall in the case handling area+concealed audio and video recording on the intelligent interrogation table+emergency alarm button
Evidence room double door interlock access control+anti magnetic cabinet biometric access+electromagnetic shielding
Perimeter protection vibration fiber+pulse electronic fence (8000V) intrusion positioning error<50 meters
IV. Counter terrorism and Emergency Response Equipment
Explosive Disposal Unit
Explosion proof tank can withstand 3kg TNT equivalent impact, and the explosion-proof mechanical arm can remotely dispose of suspicious objects;
Non lethal weapons
Sound wave drive away device (sound pressure level ≥ 130dB), electric shock capture device to block violent collisions;
Biochemical protection system
Aerosol monitoring instrument+negative pressure decontamination chamber, with a capture rate of 0.3 μ m particles>99.97%.
Technology trend:
CT type security inspection machine realizes three-dimensional reconstruction of explosives, and AI combat platform integrates multi-source data to generate threat topology maps.
