Abstract

An engine frame comprises an engine support structure and a communication device with a serial number and a wireless transceiver. The engine support structure is configured to support an engine for maintenance or transport. The communication device is configured to determine a location of the engine frame, and broadcast a report message including the location of the engine frame and the serial number to a remote server via the wireless transceiver.

Claims

1. An engine frame comprising:

an engine support structure configured to support an engine for maintenance or transport;

a communication device with a wireless transceiver and a engine frame serial number, and configured to;

determine a location of the engine frame; and

broadcast a report message including the location of the engine frame and the serial number to a remote server via the wireless transceiver.

2. The engine frame of claim 1, wherein the wireless transceiver is a cellular transceiver.

3. The engine frame of claim 2, wherein determining a location of the engine frame comprises identifying a location by means of cellular triangulation using the cellular transceiver.

4. The engine frame of claim 1, wherein the engine frame further comprises a GPS receiver, and wherein determining a location of the engine frame comprises retrieving a location from the GPS receiver.

5. The engine frame of claim 1, further comprising an RFID reader configured to energize and query an RFID device on an engine supported on the engine support structure.

6. The engine frame of claim 5, wherein the RFID reader is configured to retrieve an engine serial number from the RFID device.

7. The engine frame of claim 6, wherein the report message further comprises the engine serial number.

8. The engine frame of claim 1, wherein the engine support structure further comprises a switch actuated by presence of an engine supported on the engine support structure.

9. The engine frame of claim 8, wherein the report message further comprises a switch bit indicating a state of the switch.

10. The engine frame of claim 8, wherein the switch is an electromagnetic switch actuated by proximity to a large ferromagnetic mass.

11. The engine frame of claim 8, wherein the switch is a mechanical switch actuated by physical contact with the engine.

12. The engine frame of claim 8, further comprising an RFID reader configured to energize and query an RFID device on the engine when the switch indicates that the engine is present.

13. The engine frame of claim 12, wherein the RFID reader is configured to retrieve engine serial number, engine model number, or engine manufacturer from the RFID device, and wherein the engine serial number, engine model number, or engine manufacturer are included in the report message.

14. The engine frame of claim 1, wherein the remote server is a database server accessible to local and remote users, and which indexes engine frame location by engine frame serial number.

15. The engine frame of claim 14, wherein the remote server further indexes an engine switch bit indicating whether the engine frame is in use.

16. The engine frame of claim 14, wherein the remote server further indexes engine information corresponding to engines mounted on the engine frame.

17. The engine frame of claim 14, wherein the engine information includes an engine serial number, an engine model number, or an engine manufacturer.

18. The engine frame of claim 1, wherein the engine support structure is configured to receive an aircraft engine.

19. The engine frame of claim 1, wherein the engine support structure includes at least one attachment point configured to anchor the engine.

20. The engine frame of claim 1, wherein the wireless transceiver is a powered RFID transponder.
