Abstract

Claims (31)

1. A method for monitoring a portion of a structure implementing a control station configured to control at least one ultrasonic non-destructive testing device through a remote network, each ultrasonic non-destructive testing device comprising a multi-element ultrasonic sensor disposed on a surface of the portion of the structure, the structure being an adsorber and the portion being a wall of the adsorber, the method comprising, for each ultrasonic non-destructive testing device, the following steps of:

A) sending by the control station a first measurement request to the non-destructive testing device, at a beginning of a filling phase of the adsorber;

B) receiving by the control station a first plurality of measurement data from the non-destructive testing device, the first plurality of measurement data being measured by the multi-element ultrasonic sensor of the ultrasonic non-destructive testing device;

C) constructing by the control station a first mapping of the portion of the structure from the first plurality of measurement data;

D) subsequently to sending the first measurement request, sending by the control station a second measurement request to the non-destructive testing device, at an end of the filling phase of the adsorber;

E) receiving by the control station a second plurality of measurement data from the non-destructive testing device, the second plurality of measurement data being measured by the multi-element ultrasonic sensor of the ultrasonic non-destructive testing device;

F) constructing by the control station a second mapping of the portion of the structure, from the second plurality of measurement data; and

G) comparing by the control station the first mapping and the second mapping.

2. The method according to claim 1 , wherein the remote network is wireless.

3. The method according to claim 1 , wherein the first measurement request includes at least one first information selecting a measurement mode.

4. The method according to claim 3 , wherein the first measurement request includes at least one first operating parameter of the measurement mode.

5. The method according to claim 1 , wherein the second measurement request includes at least one second information selecting the measurement mode.

6. The method according to claim 5 , wherein the second measurement request includes at least one second operating parameter of the measurement mode.

7. The method according to claim 1 , wherein when at least one parameter representative of the comparison between the first mapping and the second mapping deviates from a threshold value, the method includes a step of triggering an indicator.

8. A control station configured to perform the steps of the method according to claim 1 .

9. A testing system comprising a control station according to claim 8 and at least one ultrasonic non-destructive testing device.

10. A method comprising providing a testing system according to claim 9 , wherein the multi-element ultrasonic sensor is disposed on a surface of a portion of a pressurised boiler equipment, the pressurised boiler equipment being an adsorber.

11. A method of measurement in a portion of a structure implementing an ultrasonic non-destructive testing device configured to be controlled by a control station through a remote network, the ultrasonic non-destructive testing device comprising a multi-element ultrasonic sensor disposed on a surface of the portion of the structure, the structure being an adsorber and the portion being a wall of the adsorber, the method comprising the following steps of:

I) receiving by the ultrasonic non-destructive testing device a first measurement request from the control station, at a beginning of a filling phase of the adsorber;

J) measuring by the multi-element ultrasonic sensor a first plurality of measurement data;

K) sending by the ultrasonic non-destructive testing device the first plurality of measurement data to the control station;

L) subsequently to receiving the first measurement request, receiving by the ultrasonic non-destructive testing device a second measurement request from the control station, at an end of the filling phase of the adsorber;

M) measuring by the multi-element ultrasonic sensor a second plurality of measurement data;

N) sending by the ultrasonic non-destructive testing device the second plurality of measurement data to the control station.

12. The measuring method according to claim 11 , wherein the measuring steps J and M comprise the following sub-steps of:

for each ultrasonic element of the multi-element ultrasonic sensor:

U) generating by the ultrasonic element of the multi-element ultrasonic sensor an incident ultrasonic wave propagating in the portion of the structure;

V) measuring by all the ultrasonic elements of the multi-element ultrasonic sensor a plurality of measurement data, the plurality of measurement data corresponding to the reception of a reflected ultrasonic wave on each ultrasonic element of the multi-element ultrasonic sensor.

13. An ultrasonic non-destructive testing device comprising a multi-element ultrasonic sensor and configured to perform the steps of the method according to claim 11 .

14. A testing system comprising a control station and at least one ultrasonic non-destructive testing device according to claim 13 .

15. A method comprising providing a testing system according to claim 14 , wherein the multi-element ultrasonic sensor is disposed on a surface of a portion of a pressurised boiler equipment, the pressurised boiler equipment being an adsorber.
