Abstract: According to one embodiment, a sensor attachment/detachment device of the embodiment includes a sensor, a bonding member, a support portion, and a release execution portion. The bonding member is bonded to a first surface of the sensor and has a function of decreasing an adhesive force. The support portion can support the sensor by directly contacting a second surface of the sensor or via another functional portion. The release execution portion performs a process of releasing the bonding member from the object by decreasing the adhesive force of the bonding member after the sensor is attached to the object by the bonding member.

Abstract: According to one embodiment, a structure evaluation system includes at least three or more sensors, a position locator, and an evaluator. The three or more sensors are arranged on surfaces different from a surface to which an impact is applied with respect to a structure at different intervals in a first direction of the structure and a second direction orthogonal to the first direction and detects elastic waves generated from the structure. The position locator locates a position of a source in which the elastic waves are generated on the basis of the elastic waves detected by each of the three or more sensors. The evaluator evaluates a deterioration state of the structure on the basis of information based on a position location process of the position locator and information indicating a position where the impact is applied.

Abstract: According to one embodiment, a structure evaluation system includes a wave guide, a first sensor, a second sensor, and a calculation part. The wave guide is formed in a rod shape, is inserted into a hole that is formed at a predetermined depth from a surface of a measurement target, and has one end fixed to a deepest portion of the hole. The first sensor is provided at the other end of the wave guide at a position that is substantially the same as the surface. The second sensor is provided on the surface of the measurement target. The calculation part estimates a depth of damage occurring in the measurement target from the surface on the basis of a first detection value of an elastic wave transmitted to the measurement target which is detected by the first sensor through the wave guide and a second detection value obtained by an elastic wave which is detected by the second sensor.

Abstract: According to one embodiment, a structure evaluation system of an embodiment includes a plurality of sensors, a position locator, a distribution generator, and an evaluator. The plurality of sensors detect elastic waves generated inside a structure. The position locator locates positions of one or more elastic wave generation sources on the basis of a plurality of elastic waves detected by each of the plurality of sensors. The distribution generator generates an elastic wave source density distribution representing a density distribution of the one or more elastic wave generation sources on the basis of a position location result of the one or more elastic wave generation sources obtained by the position locator. The evaluator evaluates damage to the structure on the basis of one or more reference distributions generated on the basis of a simulation including a random number and the elastic wave source density distribution generated by the distribution generator.

Abstract: According to an embodiment, a structure evaluation system includes a plurality of AE sensors, a signal processor, a position locator, a velocity calculator, and an evaluator. The AE sensors detect an elastic wave generated from a structure. The signal processor extracts an AE signal including information on the elastic wave by performing signal processing on the elastic wave detected by the AE sensor. The position locator derives a wave source distribution indicating a distribution of sources of the elastic waves generated in the structure on the basis of the AE signals. The velocity calculator derives a propagation velocity of the elastic wave generated in the structure on the basis of the AE signal. The evaluator evaluates the soundness of the structure on the basis of the wave source distributions and the propagation velocity of the elastic waves.
