Abstract

A method and a device for managing resources for monitoring elongate structures that can serve as elastic waveguides are provided. The structure is instrumented with a plurality of transducers capable of acquiring signals measuring characteristic quantities of elastic waves being propagated in the structure, each transducer being coupled to an electronic device installed along the structure. An electronic device comprises at least means for processing the measurement signals received from at least one transducer and a processor having code instructions for implementing steps of the resource management method consisting in: initializing an electronic device in nominal mode, the nominal mode making it possible to initiate an inspection of the elongate structure by a local analysis of elastic waves generated upon the passage of a mobile device in proximity to a transducer or initializing the device in detection mode, the detection mode making it possible to initiate, by a transducer, an emission of elastic waves in the elongate structure and make an inspection of the elongate structure by a local analysis of signals derived from the elastic waves emitted; maintaining the electronic device in nominal mode or switching the electronic device over to detection mode when an anomaly is detected in an inspection in nominal mode; maintaining the electronic device in detection mode or switching the electronic device over to assessment mode when a fault is detected in an inspection in detection mode, the assessment mode making it possible to transmit data on signals derived from elastic waves emitted in the structure to a remote server to generate a more in-depth analysis.

A method for managing resources for monitoring elongate structures that can serve as elastic waveguides, the structure being instrumented with a plurality of transducers capable of acquiring signals measuring characteristic quantities of elastic waves being propagated in the structure, each transducer being coupled to an electronic device installed along the structure, each electronic device configured to process the measurement signals received from at least one transducer, wherein the electronic device comprises a processor having code instructions for implementing steps consisting in:

initializing the electronic device in nominal mode, said nominal mode being configured to initiate an inspection of the elongated structure by a local analysis of elastic waves generated upon the passage of a mobile device in proximity to a transducer with which the electronic device is coupled, or initializing the electronic device in detection mode, said detection mode being configured to initiate, by a transducer with which the electronic device is coupled, an emission of elastic waves in the elongate structure and to make an inspection of the elongated structure and inspecting the elongated structure by a local analysis of signals derived from the elastic waves emitted;
determining if an anomaly is detected when inspecting in nominal mode, and in case, either maintaining the nominal mode or switching the electronic device to a detection mode to initiate with a transducer with which the electronic device is coupled an emission of elastic waves in the elongated structure and inspecting the elongated structure by local analysis of signals from the emitted elastic waves;
determining if an anomaly is detected when inspecting in detection mode, and in case, either maintaining the detection mode or switching the electronic device to an assessment mode, said assessment mode being configured to allow the electronic device to transmit data on signals derived from elastic waves emitted in said elongated structure when inspecting in detection mode, to a remote server to generate a more in-depth analysis.
