PURPOSE:To minimize damage by taking the best countermeasure, by giving a warning against a break of a power source by detecting precursor temperature lower than alarm temperature by a detection system which turns off the power source by detecting the alarm temperature. CONSTITUTION:When equipment temperature rises up to precursor temperature T1 during the operation of a system, a signal S1 from a temperature detector 5 is inputted to an internal interruption register R in a central processor 1 to turn on a prescribed bit. Its output signal SA is inputted to an operation system OS, and consequently external interruption processing is performed to forcibly switch a system process from a main routine to a subroutine SR. The system process returns to the main routine a certain time later. When the equipment temperature further rises up to alarm temperature T2, a power source device 2 is turned off by an alarm signal S2. |
