Abstract

The present invention relates to a method for transmitting data from an object (6) on board an aircraft (1) to a server (3) of a network of connected objects (4), the method comprising: if the aircraft (1) is detected as being in flight, the sending (108) of the data item by the object (6) to an aircraft radio communication device (10) of the aircraft (1) for communication with the ground, and the transmission of the data item by the aircraft communication system (10) to a ground station (2), for subsequent retransmission of the data item by the ground station (2) to the server (3); and, if the aircraft (1) is detected as not being in flight, the sending (116) of the data item by the object (6) to the server (3) without passing through the aircraft radio communication system (10) of the aircraft (1).

First claim

1 .- 11 . (canceled)

12 . A method comprising:
acquiring, by a motion sensor contained in an object on board an aircraft, a motion measurement of the aircraft with respect to the ground, wherein the aircraft is detected as being in flight when the motion measurement crosses a predetermined threshold; when the aircraft is detected as being in flight, sending, by the object, the data to an aeronautical radio communication device of the aircraft, and transmitting the data by the aeronautical communication system to a ground station, wherein the ground station is configured to retransmit the data to a server; when the aircraft is detected as not being in flight, sending the object of the data to the server without passing through the aeronautical radio communication system of the aircraft.

13 . The method of claim 12 , wherein the threshold has a value suitable for being crossed during a taxiing phase of the aircraft.

14 . The method of claim 12 , wherein the motion sensor comprises at least one of an accelerometer, a gyroscope and a linear speed sensor.

15 . The method of claim 12 , wherein the object sends the data in a first radio signal to a receiver on board the aircraft when the aircraft is detected as being in flight, and the receiver transmits the data to the aeronautical radio communication device via a local network of the aircraft.

16 . The method of claim 15 , wherein the local network is a wired network.

17 . The method of claim 12 , wherein the data is sent in a first radio signal having a first frequency when the aircraft is detected as being in flight, and in a second radio signal having a second frequency different from the first frequency when the aircraft is detected as not being in flight.

18 . The method of claim 12 , wherein, when the aircraft is detected as being in flight:
when the data has a value having crossed a predetermined threshold, the data is sent to the aeronautical radio communication device, otherwise, the data is stored by the object in its memory then is sent to the server of the network of connected objects without passing through the aeronautical radio communication system of the aircraft once it is detected that the aircraft is no longer in flight.

19 . The method of claim 12 , wherein the data is a temperature or a pressure in a part of the aircraft.

20 . The method of claim 19 , wherein the part of the aircraft is a tire of a landing gear, a hold or a nacelle.

21 . The method of claim 12 , wherein the data indicates whether an equipment of the aircraft is open or closed.

22 . The method of claim 21 , wherein the equipment is a cowling giving access to an engine of the aircraft.

23 . The method of claim 12 , wherein the data is a physical measurement making it possible to monitor the use, status or state of wear of an equipment.

24 . The method of claim 23 , wherein the physical measurement is a hydraulic pressure, a voltage, an amperage, a position of an equipment of the aircraft, an orientation of an equipment of the aircraft, or a deflection of a metallic element of the aircraft.

25 . The method of claim 12 , wherein the network of connected objects is of LPWAN type.

26 . The method of claim 12 , wherein the network of connected objects is LoRaWAN.

27 . The method of claim 12 , wherein the network of connected objects is Sigfox.

28 . A system comprising:
an object comprising a motion sensor configured to acquire a measurement of motion of an aircraft with respect to the ground when the system is on board the aircraft, the aircraft being detected as being in flight when the motion measurement crosses a predetermined threshold; an aeronautical radio communication device; wherein the object is configured to send data to the aeronautical radio communication device when the aircraft is detected as being in flight; wherein the aeronautical radio communication device is configured to transmit the data sent by the object from the aircraft to a ground station, wherein the ground station is configured to retransmit of the data to a server; and wherein the object is further configured to send the data to the server without passing through the aeronautical radio communication device of the aircraft when the aircraft is detected as not being in flight.
