APPARARTUS AND METHOD FOR MEASURING VIBRATION

摘要

PURPOSE: A vibration measuring device and method are provided to measure accurate vibration of a structure by correcting the measurement value according to the position of the measuring sensors to reference coordinates. CONSTITUTION: A vibration measuring device comprises a geomagnetic sensor(100) which detects an error with respect to the earth magnetic field direction, a vibration sensor(120) which measures the vibration of a structure and detects an error to with respect to the earth gravity direction, and a measurement value correcting part(140) which corrects the measurement value of the structure by the vibration sensor using the detected errors.
