SIGNAL PROCESSING APPARATUS, SERVER, DETECTION SYSTEM, AND SIGNAL PROCESSING METHOD

摘要

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.
