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 an embodiment, a signal processing apparatus includes a receiver, a time information generator, a processor, and a communicator. The receiver receives a voltage signal from a sensor that detects an elastic wave generated from a structure. The time information generator generates time information having a bit length based on a measurement continuing time period of the structure, a propagation velocity of the elastic wave, and a position identification accuracy of a generation source of the elastic wave. The processor generates detection information in which feature amount information that indicates a feature of the voltage signal and the time information that indicates a reception time of the voltage signal are in association with each other. The communicator transmits the detection information to a server.
