Abstract: A resampling circuit converts first data updated synchronously with a first clock signal into second data updated synchronously with a second clock signal asynchronous with the first clock signal and outputs the second data. The resampling circuit measures a first time interval between a plurality of successive edges of the first clock signal, and a second time interval between one of the plurality of edges of the first clock signal and an edge of the second clock signal, with a third clock signal having a higher frequency than the first clock signal and the second clock signal. The resampling circuit calculates and outputs the second data updated at the edge of the second clock signal, based on the first time interval and the second time interval, and a plurality of the first data updated at the plurality of edges of the first clock signal.

Abstract: An acquisition unit acquires the width-direction acceleration and the vertical-direction acceleration of a surface of a structure on which a moving object moves from an acceleration sensor provided in the structure on which the moving object moves. A displacement computation unit computes the vertical-direction displacement of the structure on the basis of the vertical-direction acceleration. A correlation determination unit determines the correlation between the width-direction acceleration and the vertical-direction displacement. A movement detection unit detects the movement of the moving object on the structure on the basis of the correlation.

Abstract: A dynamic response at a designated position is derived based on a deflection amount normalized by a vibration component of the dynamic response, an amplitude ratio, which is a ratio of a first deflection amount that is the normalized deflection amount indicating a distribution of a vibration amplitude of the observation point to a second deflection amount that is the normalized deflection amount indicating a distribution of a vibration amplitude of a designated position, the vibration component of the designated position derived based on the vibration component and the amplitude ratio, and the static response of the designated position derived based on the time-series data and the estimated value.

Abstract: A conversion section converts a change in signal information outputted from a vibration detector provided on a structural body from the change in the function of time into the change in the function of the distance between a moving object that moves on the structural body and the vibration detector. An attenuation characteristic calculation section calculates an attenuation characteristic of the structural body based on the signal information so converted as to represent the change in the function of the distance.
