STATE DETECTION UNIT, METHOD FOR DETECTING STATE OF STRUCTURE, AND PROGRAM FOR DETECTING STATE OF STRUCTURE

摘要

A measurement signal of a trigger detection sensor (100) by which the state of a structure is sensed is inputted into a trigger detection sensor connection circuit (11). An evaluation function unit (23) compares the measurement value acquired from the measurement signal of the trigger detection sensor (100) inputted to the trigger detection sensor connection circuit (11) and an evaluation value for that time point, and evaluates whether an extremely large external force is acting on the structure. An evaluation-value-determination function unit (22) determines the evaluation value on the basis of a reference value. A reference-value-updating function unit (21) updates the reference value in accordance with the measurement value acquired from the measurement signal of the trigger detection sensor (100) inputted to the trigger detection sensor connection circuit (11).
