Abstract
A temperature abnormality detection system of the present invention includes a first temperature sensor that measures a first temperature indicated by a target device and a second temperature sensor that measures a second temperature indicated by ambient air around the target device. A temperature difference between the first temperature and the second temperature is calculated, and when this temperature difference becomes a predetermined threshold value or more, it is determined that a temperature abnormality of the target device has occurred.
Claims11
A temperature abnormality detection system that detects a temperature abnormality of a target device installed in a board casing of a board;
- the temperature abnormality detection system comprising:
- a first temperature sensor that includes a radiation temperature sensor installed in the board casing and measures a first temperature indicated by the target device by the radiation temperature sensor;
- a second temperature sensor that measures a second temperature indicated by ambient air around the target device;
- and
- an abnormality determination unit that calculates a temperature difference between the first temperature and the second temperature, and determines that a temperature abnormality of the target device has occurred when the temperature difference becomes a predetermined threshold value or more.
