Automatic trace explosive detection system

Abstract

The invention discloses an automatic trace explosive detection system comprising a conveyor belt subsystem, a vision subsystem, a sampling subsystem, a detection subsystem and a control subsystem. Theconveyor belt subsystem, the vision subsystem, the sampling subsystem, and the detection subsystem are connected with the control subsystem. The conveyor belt subsystem is configured to transmit a to-be-detected object to a preset detection position under the control of the control subsystem. The vision subsystem is configured to acquire an image of the detected object under the control of the control subsystem and provide the image to the control subsystem. The sampling subsystem is configured to pick up sample paper to sample the detected object under the control of the control subsystem and convey the sampled sample paper to the detection subsystem. The detection subsystem is used for detecting the sample paper under the control of the control subsystem to obtain a detection result. Therefore, the amount of manual work in the detection of explosives can be reduced effectively and the detection efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of explosive detection, in particular to an automatic trace explosive detection system and method. Background technique [0002] In the past 20 years, the number of terrorist incidents has experienced a huge increase, which has made countries around the world pay more and more attention to counter-terrorism. According to data from the Global Terrorism Database, terrorist bombings accounted for more than 50% of all terrorist incidents in 2017. In addition, most terrorist bombings occurred in densely populated places, such as stations, squares, etc. Terrorist bombings posed a huge threat to civilians. This also makes explosive detection an integral part of security work. The current explosives detection is all done manually, and the operator carries a trace explosives detector to sample and detect the people coming and going at the bayonet. The existing methods have the following problems: 1. Manual detecti...

AI Technical Summary

Problems solved by technology

The existing methods have the following problems: 1. Manual detection is prone to fatigue and various unexpected situations; 2. The speed of manual detection is slow, which increases the waiting time of travelers; 3. The human resources of checkpoint detection personnel are limited, increasing The burden of detection personnel increases labor costs; 4. The existence of excessive manual intervention and the lack of interfaces make it difficult to incorporate trace explosives detection, a key security method, into the intelligent security system
