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.

Abstract: A temperature abnormality detection device includes a plurality of infrared temperature sensors respectively capable of detecting temperature in a different detection area of an equipment, and a device body including a temperature abnormality determination unit that determines that the temperature in the detection area detected by each of the plurality of infrared temperature sensors is abnormal when the temperature in the detection area is higher than a reference temperature. The plurality of infrared temperature sensors is connected to each other by crossover wiring.

Abstract: Provided is an abnormality diagnosis device capable of diagnosing an abnormality of a motor without setting many parameters. An abnormality diagnosis device includes a current measuring unit that measures a load current of the motor; a frequency analyzing unit that performs frequency analysis of the load current; and a deterioration degree calculating unit that calculates a degree of deterioration by adding up a preset number of intensity values from top in a preset frequency range.

Abstract: The temperature threshold determining device includes a temperature data storage unit, a representative temperature value determining unit, and a temperature threshold determining unit. The temperature data storage unit stores temperature data that indicates the temperature of a target apparatus during past operation. The representative temperature value determining unit determines a representative temperature value of the target apparatus during the past operation, which is derived using the temperature data stored in the temperature data storage unit. The temperature threshold determining unit determines at least one temperature threshold by using the representative temperature value during the past operation and a reference temperature value that is preset and configured to prevent the temperature abnormality.
