Intelligent security check system and method based on passive terahertz security check instrument

Abstract

The invention provides an intelligent security check system and method based on a passive terahertz security check instrument. The system comprises the passive terahertz security check instrument andan identity recognition gate, wherein the passive terahertz security check instrument and the identity recognition gate are in communication connection with a central control system, the passive terahertz security check instrument synchronously uploads terahertz imaging data generated by detection and first video image data acquired by a first visible light camera to the central control system; the identity recognition gate synchronously uploads second video image data and certificate data acquired by a second visible light camera to the central control system; and the central control system collects the terahertz imaging data and the certificate data into each personnel file according to face information in the first video image data and the second video image data. According to the invention, the terahertz imaging data is matched with the personnel certificate data to form an integrated intelligent safety monitoring system, so that personnel information can be tracked and managed conveniently.

Description

technical field [0001] The invention relates to the technical field of public security, in particular to an intelligent security inspection system and method based on a passive terahertz security inspection instrument. Background technique [0002] Our country is currently in a period of high incidence of sudden public security incidents, and the economic losses caused by such incidents reach hundreds of billions of yuan every year, and it shows a trend of increasing year by year. The high incidence of public safety incidents has attracted great attention from the state and governments at all levels. Long-term experience shows that inspections of crowded places can effectively prevent the occurrence of public safety incidents in such places. [0003] For a long time, the equipment for security inspection in crowded places such as airports and railways mainly consists of X-ray luggage inspection equipment and metal security gates or hand-held metal detectors. X-ray luggage s...

Problems solved by technology

However, in the actual application of places such as stations, subways, airports, etc., due to the large number of people, it often happens that people change their order to enter terahertz detection and luggage detection after passing through the witness comparison equipment. At this time, the system provided by this patent cannot Matching the test results with the corresponding personnel makes it impossible to track and view the test results, and it is also impossible to realize the effect of simultaneous inspection of people, evidence and objects

When there is a large flow of people in the security check, the judges can't even determine the specific person carrying the suspicious contraband, and the hand inspector needs to accurately locate the contraband for each manual touch that passes the security check in turn, and the security check efficiency is low.
