摘要： According to one embodiment, a structure evaluation system includes an impact imparting unit, a plurality of sensors, a position locator, and an evaluator. The impact imparting unit applies impacts to a second region different from a first region of a structure to which traveling sections of a vehicle, which travels on the structure, apply impacts. The plurality of sensors detect elastic waves generated in the structure. The position locator locates a position of a source of the elastic waves on the basis of the elastic waves detected by each of the plurality of sensors. The evaluator evaluates a deterioration state of the structure on the basis of a position location result of the position locator.

摘要： According to one embodiment, a transmission terminal, a time information processing device, and a synchronization method capable of improving synchronization accuracy in a wireless network are provided. According to an embodiment, a sensor system includes a sensor, a transmission terminal, and a time information processing device. The transmission terminal includes an event signal generator, an event time determiner, a communication time determiner, and a communicator. The event signal generator detects the occurrence of an event on the basis of a physical quantity detected by the sensor. The event time determiner determines a detection time of the event. The communication time determiner determines a transmission time at the time of transmission to the time information processing device. The communicator transmits time information to the time information processing device. The time information processing device includes a reception time determiner and a time information processor. The reception time determiner determines a reception time of the time information transmitted from the transmission terminal. The time information processor performs a process based on a plurality of transmission times and a plurality of reception times.

摘要： 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.

摘要： 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.
