The Cargo Security Screening Information System is a one-stop security management platform for airport cargo terminals, integrating cargo verification, X-ray image capture, screening video surveillance, centralized image interpretation, physical inspection records, personnel management, and comprehensive inquiry — making the entire cargo screening process digitalized, traceable, and information-based. Through a unified platform, the system automatically captures and stores X-ray images, video, and business data for the long term — well beyond device-local storage limits — and can quickly retrieve screening images and video by AWB, forming a complete electronic archive and evidence chain. This effectively solves the problems of scattered information, difficult traceability, and complex accountability in the traditional model. The system also supports post operation records and workload statistics for quantitative personnel performance assessment and standardized management; built-in multi-dimensional analytics provide data support for security decisions and risk early warning. With the goal of “fully visible processes, fully traceable chains, fully managed posts, and fully searchable data,” the system comprehensively improves airport cargo screening efficiency and security capability — building a solid intelligent defense line for air cargo security.
