PURPOSE:To prevent data from erasing and to remove uncertain data processing by detecting an abnormal temperature in a computer room and inputting an alarm signal to a computer to store processing data and stop the operation at the generation of the abnormal temperature. CONSTITUTION:A temperature detecting part 1 inputs a detected temperature to a comparing part 2 as digital data through a bus 11. The comparing part 2 compares the input data with an allowable temperature range of a computer which is inputted from a temperature range setting part 3 through a bus 12. When the input data exceed the allowable temperature range, the comparing part 2 applies an alarm signal to an alarm part 4 through an abnormal temperature signal line 21 and inputs a signal to the computer 7 with the highest priority, so that the computer 5 executes processing such as storing of the processing data and stop of the operation. |
