It analyzes the seismic waves obtained from the accelerometer sensor when an earthquake occurs and provides an alarm to the main control room when the acceleration exceeds the alarm set point (0.01g). Additionally, it evaluates the stability of the structure through analysis of seismic data and makes an over-determination of the operating base earthquake (OBE), thereby allowing users to analyze information about earthquakes even after earthquakes occur.
