Patent KR-20220106305-A (KR)
Inventor: PARK YOUNG KWON
IPC: G01H1/14
Filed: 2021-01-22
Abstract: Conventionally, there has been a method of converting a signal measured in a 3-axis acceleration sensor installed in a building or structure into a frequency domain through a fast Fourier transform (FFT) and analyzing the frequency domain to distinguish noise from a danger signal. However, for the fast Fourier transform, a computing system equipped with an MPU or CPU with a high operating speed was essential, and there was a problem in that safety of the building could not be determined from the measurement result. The present invention provides a building vibration measurement system using a piezoelectric sensor that can remove noise signals from signals measured in a building or structure without requiring high-speed computations and distinguish significant danger signals and thus can check the safety of the building. According to the configuration, the present invention may provide a means capable of determining a state of a building or structure that responds to external vibrations by using piezoelectric characteristics of the piezoelectric sensor.
