Abstract
An electronic device is installed in a machine where there is a possibility in occurrence of vibration or impact. The electronic device includes an acceleration detecting unit detecting acceleration in a predetermined time interval, and an impact determining unit. In a case where it is determined that an acceleration value exceeds a predetermined first threshold value, a second threshold value is calculated based on a maximum value among acceleration values of plural accelerations for a predetermined time interval after the determination. In a case where the number of accelerations where acceleration values exceeds the second threshold value among the plural accelerations is a predetermined number or less, the impact as a single-type impact is determined. In a case where the number exceeds the predetermined number, the impact as a multiple-type impact is determined. Also included is an output unit outputting a signal in a case where the impact is determined as the multiple-type impact.
