초록 ▼

A cooling abnormality detection system for external electronic equipment includes a protection unit. The protection unit includes two temperature sensors arranged in each piece of external electrical equipment to be monitored, in order to measure the temperature of each. A temperature difference measuring means receives the measured temperature from each piece of equipment and outputs a sensor failure signal when the absolute value of difference between the temperatures measured by the two temperature sensors exceeds a first predetermined value. An abnormal temperature signal is output from the temperature difference measuring means when the two measured temperatures both exceed a second value. The sensor failure signal is transmitted to the electronic equipment, while generation of the abnormal temperature alarm interrupts the power supply to the electronic equipment.
