Title: Method of using acoustic-emission data collection for monitoring and forecasting of the state of construction and technological structures
Inventor: Lifshits Mikhail Valerevich
IPC: G01N29/14
Filed: 2020-03-10
Granted: 2021-06-29
Abstract: FIELD: construction or technological structures. 
     SUBSTANCE: invention is used for monitoring and forecasting of the state of construction and technological structures by means of acoustic-emission data collection. The essence of the invention is that at least two sensors are attached to the surface of the structure that capture acoustic signals received from dynamically developing defects in the structure. The received acoustic signals from the sensors received at the first stage are stored. The location of the defect is determined by the difference in the time of reception of similar acoustic signals from the sensors, and the type of defect is determined by the nature of the acoustic signal. Stored acoustic signals are divided into at least four groups. A passive source is characterized by a monotonous decrease in the activity, amplitude and/or energy of the signal over time and saturation of the acoustic emission parameters. An active source is characterized by quasi-constant values of activity, amplitude and/or energy over time and a linear dependence of the acoustic emission parameters on the time. A critically active source is characterized by a constant increase in the values of activity, amplitude and/or energy in time and a deviation from the linear time dependence in the direction of increasing the values of the acoustic emission parameters. A super-critically active source is characterized by a further significant increase in the values of activity, amplitude, and/or energy in time and a substantial deviation from the linear time dependence in the direction of increasing the values of the acoustic emission parameters. The obtained data is used for monitoring structures. For the first two groups of sources, the monitoring mode is set, and for the next two groups, the mode of notification of the appearance and location of critical and/or super-critically active sources is set. The transition of the first two groups of sources to the next two groups is controlled. The data of the first three groups are used to predict the state of construction and technological structures in the future. 
     EFFECT: invention is aimed at providing the ability to predict the occurrence of critical events associated with internal malfunctions of construction or technological structures.
