Heat flux derivation method, the wound detection method including the derivation, and wound portion detection apparatus using the detection method

摘要

PROBLEM TO BE SOLVED: To provide a method for leading out the heating condition of an object to be measured, capable of suppressing variations of the detection results of the damaged part caused by the man power of an inspector or the like in a method for detecting the damaged part based on the surface temperature of the object to be measured, to provide a damaged part detection method including this leading method, and to provide a damaged part detector using the detection method.;SOLUTION: In a heat flux leading-out method suitable for detecting the damaged part, a plurality of representative values are respectively set in a temperature difference Δt between the damaged part and a healthy part, the size d of the damaged part and heat flux q, the relation Q between the temperature difference Δt, the size d of the damaged part and the heat flux q is determined by heat conductivity analysis in respective combinations wherein the representative values of respective parameters are altered, temperature difference Δt1 desired to be detected and the size d1 of the damaged part of the detection target are set and the heat flux q when heating the object to be measured T is determined on the basis of the predetermined relation Q in order to detect the damaged part a from the set temperature difference Δt1 and the size d1 of the damaged part.;COPYRIGHT: (C)2011,JPO&INPIT
