PURPOSE:To perform automatic processing to prevent faults such as data loss by mounting a seismometer to a computer system to identify initial vibration of an earthquake and have an interrupt to a CPU occur to start an fault prevention processing. CONSTITUTION:The initial vibration which is detected by a vibration meter 1 is sent to a decision division 2 of vibration waveform. If the detected vibration is recognized by the discrimination division 2 of vibration waveform that it exceeds certain level, an discriminates an interruption, an interruption processing is done in an interrupt processing section 4, and a fault prevention processing section 5 is activated to execute predefined fault prevention countermoves such as data saving, etc. |
