Berlin Thousands of cargo are transported daily by plane – some 70 percent in passenger aircraft. Strict controls are intended to prevent hazardous substances such as explosives smuggled on board. Existing test methods are, however, costly and time-consuming, because it lacks simply verifiable characteristics, to demonstrate the safe status of a freight item at any point of its travel.
want to change in Magdeburg, researchers at the Fraunhofer Institute for Factory Operation and Automation (IFF). Together with partners such as Lufthansa Cargo they are working on a digital fingerprint for cargo, is to reduce the burden for possible follow-ups dramatically. “Such a fingerprint can during the entire transport chain at all times accurate statements about the security status of the cargo to,” explains Olaf Poenicke, project manager at the Fraunhofer IFF.
A block of new security system is a special marker, which allows users to check whether a piece of cargo has already been x-rayed. With the prior art is the incomprehensible, the security control by X-ray machine so must every time repeated, when the piece of cargo is traveling classified somewhere as suspicious.
The researchers are also developing an RFID label to subsequent manipulation of a program to recognize. For this purpose, they position a transponder with a very thin fuse wire to the breaking edge of a packet. Will it open, tearing the wire. The program is then although still identifiable, in addition, the inspector receives but the information that the wire is damaged.
” This technology can also check all pallets . A piece of cargo with a broken wire is less, the affected program about the ID can accurately identify, “said Poenicke. In addition, can be detected by means of 3D scan the contour of the range. If later a package placed on the pallet, the contour changes.
