INTERNAL TEMPERATURE MEASUREMENT METHOD AND INTERNAL TEMPERATURE MEASUREMENT DEVICE

摘要

A method includes measuring a first temperature difference between first heat entry and discharge parts on a first heat transfer path extending from a portion of a surface of the object to the first heat discharge part using a first thermopile, and measuring a second temperature difference between a second heat entry and discharge parts on a second heat transfer path extending from another portion of the surface of the object to the second heat discharge part using a second thermopile, and measuring a reference temperature at a predetermined position on the first or second heat transfer path using a temperature sensor, and calculating the internal temperature of the object using the measured first and second temperature differences, and the reference temperature, and at least one predetermined value excluding a physical property value of a non-heating part of the object located at a surface side of the object.

1. An internal temperature measurement method for measuring an internal temperature of an object, the method comprising:
measuring a first temperature difference between a first heat entry part and a first heat discharge part on a first heat transfer path using a first thermopile, the first heat transfer path extending from a portion of a surface of the object to the first heat discharge part, and measuring a second temperature difference between a second heat entry part and a second heat discharge part on a second heat transfer path using a second thermopile, the second heat transfer path extending from another portion of the surface of the object to the second heat discharge part and having a thermal resistance different from a thermal resistance of the first heat transfer path, and measuring a reference temperature using a temperature sensor, the reference temperature being a temperature at a predetermined position on the first heat transfer path or the second heat transfer path; and calculating the internal temperature of the object using the first temperature difference, the second temperature difference, and the reference temperature measured in the measuring step and at least one predetermined value excluding a physical property value of a non-heat generating part of the object located at a surface side of the object.
