System and method for remotely updating data for computer devices included in an aircraft
A system for updating data for computer devices included in an aircraft, the computer devices being, when the data is updated, liable to affect or not the safety of an operator performing maintenance, the system is included in the aircraft and includes a data loading device, a communication device, a data router and a module for detecting at least one maintenance operation on the aircraft. The system includes: means, included in the communication device, for receiving a command for updating a computer device; means, included in the communication device, for controlling the data loading device and the data router in order to transfer the updating data to the computer device; and means, controlled by the module for detecting at least one maintenance operation on the aircraft, for blocking the updating if at least one signal indicating that a maintenance operation is being performed on the aircraft is received.
1. A data updating system for computer devices included in an aircraft, the computer devices being, when the data of the computer device are updated, liable or not to affect the safety of an operator carrying out maintenance, wherein the system is included in the aircraft and comprises:
a data loading device,
a communication device,
a data router,
a module for detecting at least one maintenance operation on the aircraft, the data router being connected to the data loading device, the communication device being configured for receiving commands from a device located outside the aircraft, and
circuitry causing the system to perform:
receiving, by the communication device, a command for updating a computer device,
controlling, by the communication device, the data loading device for transferring data for updating the computer device to the data router in response to the command for updating the computer device being received,
controlling, by the communication device, the data router for transferring the updating data to the computer device in response to the command for updating the computer device being received,
detecting that at least one signal indicating that a maintenance operation is being performed on the aircraft is received by the module for detecting at least one maintenance operation, and
blocking, by the module for detecting at least one maintenance operation on the aircraft, the data for updating the computer device or at least one command for transferring the updating data in response to detecting that at least one signal indicating that the maintenance operation is being performed on the aircraft is received by the module for detecting at least one maintenance operation.
2. The system according to claim 1 , wherein the module for detecting at least one maintenance operation on the aircraft is included in the communication device and the blocking blocks the commands of the data loading device and the commands of the data router.
3. The system according to claim 1 , wherein the module for detecting at least one maintenance operation on the aircraft is included in the data loading device and the blocking blocks the transfer of the data for updating the computer device to the data router.
4. The system according to claim 1 , wherein the module for detecting at least one maintenance operation on the aircraft is included in the data router and the blocking blocks the transfer of the updating data to the computer device.
5. The system according to claim 1 , wherein the module for detecting at least one maintenance operation on the aircraft is included between the communication device and the data router and the blocking blocks the commands of the data router.
6. The system according to claim 1 , further comprising a device for detecting weight on at least one wheel of the aircraft and the device for detecting weight device blocks the data for updating the computer device or blocks at least one command for transferring the updating data.
7. The system according to claim 1 , wherein the module for detecting at least one maintenance operation on the aircraft comprises circuitry causing the module for detecting at least one maintenance operation on the aircraft to detect a command generated by a maintenance operator.
8. The system according to claim 1 , wherein the module for detecting at least one maintenance operation on the aircraft comprises circuitry causing the module for detecting at least one maintenance operation on the aircraft to detect a condition that the aircraft is not in a maintenance phase, and the updating operation is not enabled.
9. The system according to claim 1 , wherein the updating data are received by means of a link with a data device for transferring updating data located outside the aircraft.
10. A method for updating data for computer devices included in an aircraft, the computer devices being, during the updating of the data of the computer device, liable or not to affect the safety of an operator performing maintenance, wherein the aircraft comprises a data loading device, a communication device, a data router and a module for detecting at least one maintenance operation on the aircraft, the data router being connected to the data loading device, the communication device being configured for receiving commands from a device located outside the aircraft, and wherein the method comprises:
receiving, by the communication device, a command for updating a computer device,
controlling, by the communication device, the data loading device for transferring data for updating the computer device to the data router in response to the command for updating the computer device being received,
controlling, by the communication device, the data router for transferring the updating data to the computer device in response to the command for updating the computer device being received,
detecting that at least one signal indicating that a maintenance operation is being performed on the aircraft is received by the module for detecting at least one maintenance operation, and
blocking, by the module for detecting at least one maintenance operation on the aircraft, the data for updating the computer device, or blocking at least one command for transferring the updating data in response to detecting that the at least one signal indicating that the maintenance operation is being performed on the aircraft is received by the module for detecting at least one maintenance operation.
11. A non-transitory storage medium that stores a computer program comprising instructions for implementing the method according to claim 10 when said program is executed by a processor.
