Problems solved by technology

[0014] However, in the above-mentioned background technology, when a micro earthquake (Micro Earthquake) is generated, the background noise cannot be distinguished from the amplitude (Amplitude) of the seismic wave, and the detection performance of the seismic wave is remarkably degraded. Therefore, it is impossible to accurately determine the seismic factor.

Abstract

The present invention relates to a verification system and method for measuring a sensor by using a seismograph, which perform time zone bandpass filter and hilbert transform to seismological observation measurement data of a novel seismological observation instrument and an aging seismometer or shaking table testing data so as to raise a response spectrum amplitude and phase determination efficiency of the seismograph. According to the invention, the response spectrum of a seismic sensor is obtained through time zone bandpass filter and hilbert transform to the seismological observation measurement data of a novel seismological observation instrument and an aging seismometer or the shaking table testing data, thereby providing the effects of raising the amplitude and phase determination accuracy. Moreover, characteristics of the sensor can be provided irrelevant to the kind of the sensor to be measured, thereby improving the inconvenience of requirement of introducing sensors of the same kind.

Description

technical field [0001] The present invention relates to a measurement sensor verification system and method using a seismograph, and in more detail, relates to a time zone band-pass filter for seismic observation measurement data or shaking table test data of novel seismic observation instruments and aging seismometers A measurement sensor verification system and method using a seismograph to improve the accuracy of the response spectrum amplitude and phase measurement of the seismograph using a Bandpass filter and a Hilbert transform. Background technique [0002] The earthquake monitoring system is a device that measures the voltage of a seismometer sensor (velocity, acceleration) that mainly uses a seismograph to measure ground movement. When purchasing a new seismograph, it is necessary to confirm the performance of the seismometer and sensor that the manufacturer suggested. There may be a need to verify the performance of older, aging seismic monitoring systems located ...
