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.
Claims10
A temperature abnormality detection system that detects a temperature abnormality of a target device installed in a board;
- the temperature abnormality detection system comprising:
- a first temperature sensor that measures a first temperature indicated by the target device;
- 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.
A temperature abnormality detection method that detects a temperature abnormality of a target device installed in a board, the temperature abnormality detection method comprising:
- measuring a first temperature indicated by the target device by a first temperature sensor, and measuring a second temperature indicated by ambient air around the target device by a second temperature sensor;
- and
- calculating a difference between the first temperature and the second temperature, and determining that a temperature abnormality of the target device has occurred when the difference becomes a predetermined threshold value or more.
A computer-readable recording medium non-transitorily storing a program for causing a computer to execute a temperature abnormality detection method that detects a temperature abnormality of a target device installed in a board, the temperature abnormality detection method comprising:
- measuring a first temperature indicated by the target device by a first temperature sensor, and measuring a second temperature indicated by ambient air around the target device by a second temperature sensor;
- and
- calculating a difference between the first temperature and the second temperature, and determining that a temperature abnormality of the target device has occurred when the difference becomes a predetermined threshold value or more.
