TEMPERATURE THRESHOLD DETERMINATION DEVICE, TEMPERATURE ABNORMALITY DETERMINATION SYSTEM, TEMPERATURE THRESHOLD DETERMINATION METHOD, AND PROGRAM

摘要

To provide a temperature threshold determination device capable of determining an appropriate temperature threshold even when an object device malfunctions during test operation of the object device intended to determine a temperature threshold.SOLUTION: A temperature threshold determination device included in a temperature abnormality determination device 30 includes a temperature data storage unit 35, a representative temperature value determination unit 37a, and a temperature threshold determination unit 37b. The temperature data storage unit 35 stores temperature data representing the temperature observed when an object device 10 was operated in the past. The representative temperature value determination unit 37a determines a representative temperature value Trep in the past operation of the object device 10 which is derived using the temperature data stored in the temperature data storage unit 35. The temperature threshold determination unit 37b determines at least one temperature threshold Tth using the representative temperature value Trep in the past operation and a predesignated reference temperature value Tref for use in preventing a temperature abnormality.SELECTED DRAWING: Figure 3
