In airport cargo terminal operations, traditional cargo tracking relies on manual records, making it difficult to know the actual location and movement of loose and palletized cargo in time — resulting in no early warning for late-arriving or short-shipped cargo, inefficient cargo search and handling, high labor intensity, and constraints on the precision and convenience of customs supervision. Built on Bluetooth AoA positioning and RFID, the system automatically locates and tracks loose and palletized cargo in real time, accurately reporting cargo position and movement within the warehouse. Terminal operators can monitor CBA cargo status in real time with instant alerts on irregularities; cargo search and handling efficiency is greatly improved and labor costs reduced. The system also provides complete cargo trajectory data for customs supervision, supporting more flexible and efficient import / export logistics services — comprehensively raising terminal operations and regulatory compliance capability.
