1、 Programme background
In recent years, terrorist attacks and extreme violence have occurred frequently, resulting in huge loss of personal and property safety and significant social and economic impact. With the continuous expansion of the city scale and the increasingly complex social situation, the contradiction between the limited security resources and the growing demand of the society is becoming increasingly prominent, which leads to the great challenge of urban safety.
The problems of traditional security inspection are as follows
Visual fatigue: the security check-in personnel need to be replaced every 15-20 minutes.
Vulnerable to interference: noisy environment, chatting, playing mobile phone, being consulted, emotion, illness, etc.
Data out of Sync: security data out of sync, once a security incident occurs, it is impossible to report and arrange the police force at the first time.
Difficult data traceability: the data of the security inspection machine is not connected to the Internet, which makes it difficult to trace the data, and the follow-up investigation and tracking are difficult to carry out.
Data value is not mined: a large number of security inspection data are stored locally, without unified archiving and analysis, and resources cannot be used effectively.
2、 Overall solution advantages
Comprehensive application of X-ray imaging technology (security machine), intelligent recognition technology (Hunter intelligent security server), ultra wideband pulse microwave reflection technology (desktop drug and explosive detector), photoionization high resolution ion mobility spectrometry technology (desktop liquid detector), electromagnetic compatibility design and anti vibration design technology (security door), metal detection (handheld metal detector), etc Advanced technology, effective prevention and control of knives, guns and ammunition, flammable and corrosive articles, explosives and other dangerous contraband, a powerful deterrent to terrorists and extremists.
Real time collection and intelligent identification of X-ray images, portraits, video surveillance and other information of passengers’ carry on luggage, and storage, timely reporting in case of security threats, which can be used for investigation and analysis afterwards. The security inspection data of each information island are collected to the central management platform for big data analysis, which provides data support for the reasonable arrangement of security inspection and police officers.

Introduction to the platform
Center management platform, real-time receiving contraband alarm and linkage scene video recording, real-time control security scene. At the same time, it can capture and compare the faces of the people who have passed the contract, realize the integration of the person and the contract, and alarm the suspected person, which effectively combines the traditional physical inspection with the human inspection. The platform also has the function of data statistics and analysis. Through the statistics of daily package data, the quantity of packages and dangerous goods can be analyzed, which can provide auxiliary information for the deployment of security personnel and police officers, and realize the intelligent management of security inspection.
Brief introduction of algorithm
Core technology | deep learning + structured data display
By collecting the X-ray image information of the actual package of the security inspection machine, the learning samples of cutting tools, bottled liquid and other items are formed. Through the learning convergence of the deep learning model, the features of the items are automatically identified, and finally the structured data of the items are formed for display.
