Lufthansa Technik is the world’s leading professional company in the maintenance of commercial aircraft, aero engines and parts. Recently, it was decided to choose Motorola’s RFID solution for tracking the parts needed for aircraft maintenance.
Motorola has become the world’s leading supplier of RFID solutions since it merged with Symbol Technology.
RFID technology has been used in other business sectors for some time, such as the retail industry and the clothing industry. Because the aviation industry also needs to adopt high technology, but the application of RFID technology in the aviation industry must be improved, and corresponding professional engineering knowledge must be possessed. For example, RFID devices must withstand severe short-term temperature fluctuations here, must be able to withstand rapid air pressure changes, and be able to work normally in such a harsh environment.
It is well known that UHF RFID chips can receive and reflect UHF, and can complete two-way communication within a range of 30-50 cm, without visual inspection, and can penetrate the dashboard of the cockpit. Such RFID chips need to be further improved so that they can still work normally even if they are pasted on the metal shell.
The use of RFID technology for the maintenance of aircraft parts can greatly simplify many operating procedures. The RFID chip can quickly locate and identify a certain component, and confirm its maintenance status at any time. Information that was previously available from a central database can now be obtained through simple radio waves. Such a system usually requires at least two components, namely an RFID chip or tag and a reader. The tag is installed on the surface or inside of the object to be communicated, and the reader is used to identify it. The reader can identify any parts in its vicinity that have RFID tags installed. Passive UHF tags transmit information by backscattering the carrier wave emitted by the reader, and its energy comes from the radio signal of the reader. This means that the tag itself does not require energy, and its function is completely passive.
After a successful trial operation in the Hamburg repair center, Lufthansa Technik decided to use Motorola’s RFID solution, including the main repair center in Frankfurt and the repair stations at major airports in Germany, as well as another 50 repair stations distributed around the world.
At present, the time-consuming manual recording method is adopted for parts maintenance and ordering, and human error is inevitable. If parts are misordered or sent out, the maintenance plan will be interrupted. After adopting RFID technology, RFID UHF tags will be affixed to the aircraft parts to record detailed information of the parts.
Lufthansa Technik is preparing to use Motorola’s MC9090-G RFID palm-size reader and XR480 fixed RFID reader to read RFID tag information. The flow and usage information of parts can be tracked at any time, the information collection of used parts, and the authenticity of parts are fully automated. This can reduce the probability of manual recording errors and the probability of incorrect parts being issued. The trial operation of Lufthansa Technik has shown that the total time required for maintenance of aircraft parts can be significantly reduced. (Text/Zhuang Biaowei)
