Abstract

A method for inspecting a plurality of elements of an industrial plant includes developing an application having a user interface with a command for each element to be inspected; repeatedly acquiring image data of the elements of the industrial plant using a mobile device, and storing the image data in an acquisition memory, each image datum comprising at least one image and a timestamp indicating a time at which the image datum was acquired; activating commands at respective activation times; and associating the image data with the elements. The image data is associated with a given element being chosen exclusively from the image data having a timestamp between the time of activation of the command corresponding to said element and the time of activation of either the preceding or the following command.

Claims (48)

1 . A method of inspecting a plurality of elements of an industrial plant, the method comprising the steps of:

creating an application having a user interface having a command for each element to be inspected;

repeatedly acquiring image data of the elements of the industrial plant using a mobile device, and storage of the image data in an acquisition memory, each image data comprising at least one image and a timestamp indicating a time at which the image data was acquired;

activating the commands at respective activation times; and

associating the image data with the elements, the image data associated with a given element being chosen exclusively from the image data having a timestamp between the time of activation of the command corresponding to said element and the time of activation of a preceding or following command,

wherein the associating step comprises, for each element, the following sub-steps:

transferring all image data having a timestamp between the time of activation of the command associated with said element and the time of activation of either the preceding or the following command, from the acquisition memory into a receiving memory; and

transferring at least one of said image data from the receiving memory to a data storage specific for said element,

wherein the associating step comprises a sub-step of erasing the acquisition memory after the sub-step of transferring the image data to the receiving memory has ended.

2 . The method according to claim 1 , wherein the sub-step of transfer from the acquisition memory to the receiving memory is initiated by the activation of the command corresponding to said element or by activation of the following command.

3 . The method according to claim 1 , wherein the associating step comprises a plurality of successive sub-steps, each sub-step corresponding to the acquisition of image data relating to one of the elements, the command corresponding to said element being activated at an end of said sub-step.

4 . The method according to claim 1 , wherein the associating step comprises a sub-step of writing, in each of the image data associated with one of the elements, an identification reference of said element.

5 . The method according to claim 1 , wherein the associating step comprises a sub-step of assigning to each of the image data associated with one of the elements, a file name containing a reference for identifying said element.

6 . The method according to claim 1 , wherein the industrial plant is a nuclear reactor, the elements being selected from the following list:

elements belonging to control rod cluster command mechanisms;

elements carried by a closing head of a reactor pressure vessel;

elements located in a reactor zone with a dose equivalent flow-rate greater than 1 mSv/h.

7 . The method according to claim 1 , wherein the mobile device is selected from the following list: a camera, a video camera, a thermal camera, an endoscope, a fiberscope.

8 . The method according to claim 1 , wherein the user interface comprises a schematic representation of the plant, each command being a touch-sensitive zone of the schematic representation.

9 . The method according to claim 8 , wherein the touch-sensitive zone has a first appearance when the command has not yet been activated, and a second appearance different from the first appearance when the command has already been activated.

10 . A method of inspecting a plurality of elements of an industrial plant, the method comprising the steps of:

creating an application having a user interface having a command for each element to be inspected;

repeatedly acquiring image data of the elements of the industrial plant using a mobile device, and storage of the image data in an acquisition memory, each image data comprising at least one image and a timestamp indicating a time at which the image data was acquired;

activating the commands at respective activation times; and

associating the image data with the elements, the image data associated with a given element being chosen exclusively from the image data having a timestamp between the time of activation of the command corresponding to said element and the time of activation of a preceding or following command,

wherein the user interface comprises a schematic representation of the plant, each command being a touch-sensitive zone of the schematic representation.

11 . The method as recited in claim 10 wherein the framework of investigations is the Primary Hydrostatic Test.

12 . A method of inspecting a plurality of elements of an industrial plant, the method comprising the steps of:

creating an application having a user interface having a command for each element to be inspected;

repeatedly acquiring image data of the elements of the industrial plant using a mobile device, and storage of the image data in an acquisition memory, each image data comprising at least one image and a timestamp indicating a time at which the image data was acquired;

activating the commands at respective activation times; and

associating the image data with the elements, the image data associated with a given element being chosen exclusively from the image data having a timestamp between the time of activation of the command corresponding to said element and the time of activation of a preceding or following command,

wherein the industrial plant is a nuclear reactor, the elements being selected from the following list:

elements belonging to control rod cluster command mechanisms;

elements carried by a closing head of a reactor pressure vessel;

elements located in a reactor zone with a dose equivalent flow-rate greater than 1 mSv/h;

elements located in rooms close to the pressure vessel;

elements located at the bottom of the spent fuel pool; or

elements located behind pipes;

the method being used within a framework of investigations requiring a plurality of shots of different equipment items located in a plurality of rooms.

13 . An inspection set for inspecting a plurality of elements of an industrial plant, the inspection set comprising:

an application having a user interface with a command for each element to be inspected; and

a mobile acquisition device for image data of the industrial plant and an acquisition memory configured for storing such image data, each image datum comprising at least one image and a timestamp indicating a time at which the image datum was acquired;

the application being configured so that an activation of the commands, at respective activation times, initiates a transfer from the acquisition memory into a receiving memory of all image data having a timestamp between the time of activation of said command and the time of activation of a preceding command,

wherein the inspection set comprises a data storage specific for each element.

14 . The inspection set according to claim 13 , wherein the mobile device is selected from the following list: a camera, a video camera, a thermal camera, an endoscope, a fiberscope.

15 . The inspection set according to claim 13 , wherein the user interface comprises a schematic representation of the industrial plant, each command being a touch-sensitive zone of the schematic representation.

16 . The inspection set according to claim 15 , wherein the touch-sensitive zone has a first appearance when the command has not yet been activated, and a second appearance different from the first appearance when the command has already been activated.
