Zusammenfassung:	The present invention is an earthquake analysis apparatus used in an earthquake monitoring system used in nuclear power plants to predict a current error of the earthquake sensor, and performs the earthquake data analysis, sensor calibration notification, and the like by reflecting a predicted error. According to the present invention, the error estimation method obtains a sensor feature value through a database of sensor calibration records, estimates a current sensor error to reflect the error in the earthquake analysis, and sends a calibration request when the analysis result of the sensor measurement data and the error reflection data has a difference more than a standard value, thereby improving the reliability of the earthquake monitoring system. 본 발명은 원자력발전소에서 사용되는 지진감시시스템에서 사용되는 지진 분석 장치로 지진 센서의 현재 오차를 예측하고, 예측된 오차를 반영하여 지진 데이터분석, 센서 교정알림 등을 수행한다. 본 발명에 따른 오차예측 방법은 센서 교정 기록의 데이터베이스화를 통해 센서 특성값을 구하고 현재의 센서 오차를 예측하여 지진 분석에 반영하며, 센서 측정 데이터와 오차 반영 데이터의 분석결과가 기준치 이상의 차이가 있을 경우 교정 요청을 보냄으로써 지진감시시스템의 신뢰성을 향상시킨다.
