Dangerous Liquid Detection with Ultra-Wideband Pulse Microwave Reflection & Thermal Conductivity Technology

Technical principles and core characteristics

Ultra wideband pulse microwave reflection method (UWB-PMR)

Using 0.1-10GHz ultra wideband pulses to penetrate packaging materials (glass/plastic/ceramics, etc.), identifying liquid molecular structures through analysis of reflection spectrum differences, and achieving non-contact detection.

Original bottle bottom scanning technology: detection can be completed with only a small amount of liquid, with an accuracy rate of over 99%.

Thermal conductivity assisted verification

Synchronize measurement of liquid thermal conductivity characteristics, establish a dual-mode fingerprint database (such as flammable liquid thermal conductivity<0.1W/m · K), and cross validate with microwave data to reduce false alarm rates.

Technological innovation breakthrough

Technological dimension enables the realization of industrial value

Non radiation safety design: Photon energy is only one millionth of X-rays, suitable for crowded places (airports/subways)

Multi material compatibility penetrates common containers other than metal outer packaging and supports screening of aluminum cans/glass bottles/plastic bottles

Millisecond level response, single detection time<1 second, fast passage guarantee for peak traffic channels

Compared to traditional liquid detection techniques:

Indicator UWB Thermal conductivity dual-mode technology X-ray transmission method

Radiation risk zero ionizing radiation requires radiation shielding

Effective identification of trace liquid at the bottom of the bottle requires full bottle liquid for deep detection

Metal interference can penetrate non-metallic coated metal containers and be completely shielded

Core application scenarios

Public transportation security

Airport/subway liquid rapid security check: intercepting flammable and explosive materials such as gasoline and nitric acid (experimental interception rate of 99.8%);

Industrial production safety

Chemical plant raw material leakage monitoring: real-time identification of corrosive liquid leakage in pipelines;

Lithium battery electrolyte quality inspection: Non contact analysis of solvent purity (thermal conductivity deviation<± 2%).

Special place control

Screening of banned liquids in sports venues/music festivals, processing over 100000 containers per day.

Technological Evolution Direction

Artificial Intelligence Enhancement

The CNN network integrates microwave reflection spectra and thermal conductivity curves, increasing the recognition rate of the new camouflage liquid to 99.5%;

Miniaturization integration

Handheld detectors weigh less than 1.5kg and are suitable for mobile inspections;

Quantum sensing empowerment

Superconducting nanowire sensors improve microwave signal-to-noise ratio (sensitivity+30dB).

This technology has formed a security industry chain worth billions, with Chinese manufacturers accounting for over 40% of the global market share.
