Abstract

This invention relates to a control installation (1) of a turbo-machine, comprising:

• • a regulation device (2),
  • a unit (4) located remotely from the device (2) by which it is controlled,
  • a verification system (6) of the unit, comprising:
  • an emitting/receiving antenna (8) connected to the device (2),
  • a passive radiofrequency identification chip (12) mounted on the unit and incorporating information concerning this unit, wherein the chip (12) is designed to emit to the antenna (8) a radiofrequency signal comprising the information, in response to a radiofrequency signal sent by the antenna (8) to verify the unit,

The installation is such that the antenna (8) is mounted on the unit (4).

Claims

1. Control installation of a turbo-machine, characterised in that it comprises:

a turbo-machine regulation device,

at least one turbo-machine unit located remotely from said regulation device by which it is controlled, and to which it is electrically connected, and

a verification system of said unit, said system featuring;

an emitting/receiving antenna electrically connected to said regulation device,

a passive radiofrequency identification chip comprising an antenna and an electronic chip, wherein said passive radiofrequency identification chip is mounted on said unit and incorporates information concerning this same unit, wherein said passive radiofrequency identification chip is designed to emit to said emitting/receiving antenna a radiofrequency signal comprising said information, in response to a radiofrequency signal sent by said emitting/receiving antenna to verify said unit,

said installation is also characterised in that said emitting/receiving antenna is mounted on said unit, and in that said information concerning the unit comprises at least one of the following items of data;

data concerning the characterisation of the unit,

data concerning the part number and serial number of the main components of the unit,

data concerning the manufacturing and repair dates of the unit,

data concerning the manufacturer of the unit, in the form of a specific encrypted code.

2. Control installation according to claim 1, characterised in that said emitting/receiving antenna is positioned opposite said passive radiofrequency identification chip.

3. Control installation according to claim 1 or claim 2, characterised in that said emitting/receiving antenna is positioned at a distance (d) from said passive radiofrequency identification chip less than or equal to 1 cm.

4. Control installation according to claim 1, characterised in that said passive radiofrequency identification chip is attached to a removable element of said unit.

5. Control installation according to claim 4, characterised in that said removable element of said unit is a screwed element on a body of the unit.

6. Control installation according to claim 5, characterised in that said screwed element is in the form of a bolt or a plug.

7. Control installation according to claim 4, characterised in that said removable element of said unit is an identification and characterisation plate of said unit.

8. Control installation according to claim 4, characterised in that said passive radiofrequency identification chip is embedded or forced into said removable element.

9. Control installation according to claim 4, characterised in that said emitting/receiving antenna is also attached to said removable element.

10. Control installation according to claim 1, characterised in that said unit is a hydro-mechanical unit, a fuel monitoring unit or a sensor.

11. Control installation according to claim 1, characterised in that it comprises:

several turbo-machine units positioned remotely from said regulation device by which they are controlled, and to which they are electrically connected, and

a verification system specific to each unit, wherein each system features;

an emitting/receiving antenna electrically connected to said regulation device,

a passive radiofrequency identification chip comprising an antenna and an electronic chip, wherein said passive radiofrequency identification chip is mounted in said associated unit and incorporates information concerning this same associated unit, wherein said passive radiofrequency identification chip is designed to emit to said emitting/receiving antenna a radiofrequency signal comprising said information, in response to a radiofrequency signal sent by said emitting/receiving antenna to verify said associated unit,

wherein said installation is also characterised in that each emitting/receiving antenna is mounted on its associated unit.

12. Control installation according to claim 11, characterised in that it features a switch comprising several outputs each associated to one of the emitting/receiving antennae of the verification systems.

13. Turbo-machine comprising a control installation according to claim 1.
