A general abnormal heating detection method in an electronic device is limited to an object to be monitored, and cannot cope with heating of an object of which overheating is unexpected. To correct this problem, temperature data are acquired from a plurality of temperature sensors distributed in the device to be protected, the parameter indicating temperature distribution pattern in the device is calculated on the basis of the acquired temperature data, and an alarm signal is output when the calculated parameter indicating temperature distribution pattern deviates from a predetermined reference. |
