Intelligent Security Image Judgment for Tangshan Railway Station of Beijing Railway Bureau Group Co., Ltd.

The jurisdiction of Tangshan Railway Station covers multiple stations, with security checkpoints widely distributed and security forces at each station relatively dispersed, and the training cycle for image judgment personnel is relatively long. The project deploys an intelligent security image judgment system for some stations of Tangshan Railway Station. Through the collection and analysis of security inspection image data, it achieves real-time detection and warning of firearms and ammunition, flammable liquids, explosives, knives, sharp instruments, blunt instruments, military and police equipment, tools, and flammable and explosive items hidden in passenger luggage.

Through a proprietary image data segmentation method, the system conducts all-round scanning of passenger packages in layers and categories, assisting check-in personnel in quickly locking onto prohibited items. The system is compatible with security inspection machines of different brands and can be directly connected on the basis of existing security check channels, reducing equipment replacement costs. Using a powerful prohibited item recognition algorithm, the system can accurately identify flammable and explosive liquid components carried in passenger packages, such as alcohol, kerosene, gasoline, diesel, pesticides, paint, perfume, floral water, and various alcohol-containing spray products, and accurately annotate the liquid components, greatly improving the detection rate of liquid items.

Under the multi-station deployment mode, each station adopts unified technical standards and operating procedures. Security personnel take up their posts after unified training, reducing the cost of personnel deployment among different stations. The system records and summarizes recognition results, providing data reference for the railway station to uniformly grasp the security operation status of each station and reasonably arrange personnel strength.

After the project was put into use, the efficiency of security image judgment and the ability to intercept prohibited items at some stations of Tangshan Railway Station were improved, and the security work at each station became more standardized and unified, providing strong support for the daily operation of stations along the line and the safe travel of passengers.
