1. A multilevel and multidimensional security inspection method is characterized in that 3 processes are set, and the processes are as follows:

the first process is as follows:

(11) image fence: the method comprises the steps that a light field technology is utilized to realize multi-target rapid snapshot in a visual angle scene, the multi-target rapid snapshot is transmitted to a background database in time, and portrait comparison and identification are completed in a second level; giving an alarm to key attention personnel in real time, and implementing manual key security inspection or gate machine no-pass;

(12) electronic fence: reading and storing an IMEI code, an IMSI code and an MAC address of a mobile phone of a person entering an airport, and analyzing and early warning with key attention personnel in a database;

(13) terahertz polarization: whether passengers in the remote detection area carry explosives such as guns, explosives, control tools and the like or not is detected; detecting contraband and explosives in the passenger bag by using X-rays and ion mobility spectrometry; liquid is checked by utilizing Raman spectrum; checking whether a person carries prohibited articles or not by utilizing the terahertz human body security check instrument in a non-contact and non-stop manner;

the second process: collecting face fingerprint information, carrying out person-card integrated comparison with identity card information, and associating with a gate;

the third process:

(31) the terahertz human body security check instrument carries out non-contact human body security check;

(32) case security inspection: the X-ray security check instrument observes the bags, is associated with the first security check and the second security check, and is necessary to carry out fine check on the bags of key attention personnel; the Raman spectrometer is used for analyzing the components of the suspicious articles in the case, so that the types and the contents of the mixed substances can be preliminarily judged.

Technical Field

The invention relates to the technical field of security, in particular to a security inspection method for public transport entrances and exits of subways, airports, stations and the like.

Background

The first-line urban public transport is developed and has a large number of people, and brings huge pressure to security inspection of public transport entrances and exits such as subways, airports and stations in the peak time of traveling. Some key security inspection parts have to adopt ways such as queuing security inspection, manual visual inspection judgment and the like to improve passenger flow entrance efficiency due to large flow of people and small entrance and exit, but can increase the hidden danger of dangerous goods carriers passing.

How to effectively improve the passenger flow and realize fine safety inspection provides a challenge for the current public security department.

Disclosure of Invention

The invention aims to provide a multi-level and multi-dimensional security inspection method, which integrates and applies various security inspection technologies, realizes quick passing and fine inspection of a security inspection channel and saves labor cost.

The technical scheme of the invention is as follows:

(33) the Raman spectrometer is used for analyzing the components of the suspicious articles in the case, so that the types and the contents of the mixed substances can be preliminarily judged.

The invention comprehensively applies the technologies of image fences, electronic fences, terahertz, millimeter waves and the like, and builds a multi-level multi-dimensional intelligent security inspection system according to the idea of full coverage, non-contact and no stay, and the system is deployed and used in crowded places such as airports, railway stations, subways and the like, can realize quick passing and fine inspection of security inspection channels, and saves the labor cost.

Detailed Description

The invention adopts the following technical ideas:

1. the technology of intelligent probe, light field, portrait comparison and the like is utilized to snapshot the face, compare with a key attention personnel database, mark out the personnel needing attention, and give an alarm and push in real time.

2. By utilizing the electronic fence technology, IMEI codes, IMSI codes and MAC addresses of mobile phones within a certain range are read, and compared with mobile phone information of key attention personnel in a database for early warning.

3. By utilizing passive terahertz and AI technologies, the system can image the person in real time, intelligently alarm when finding suspicious objects and shoot the person.

4. The detection of explosives and contraband articles is carried out on the carried luggage by utilizing the technologies of X-ray, Raman, ion mobility spectrometry and the like.

5. The security inspection is carried out on the personnel who enter the customs by utilizing the active millimeter waves, and the existing manual security inspection is replaced.

And (4) performing control alarm on escapers, terrorists, case-involved persons, virus-involved persons, stability-involved persons and mental patients. And integrating various detection equipment alarm information, and performing unified display on the management platform. And distributed to PDAs and on-site command centers.
