After pilot system using the present invention, internal heat resource and hygrosensor Simulated GlS internal high pressure can be utilized to lead
Hot localised points of the bar caused by poor contact, and can get its actual temp value.Applying different heat to internal heat resource
When amount, infrared imaging measurement is carried out using infrared thermography simultaneously external, obtains the infrared image under different temperatures, it will be red
Outer image is compared with heat source temperature occurrence, obtains the pass between external detection result and internal hot(test)-spot temperature occurrence
System.After obtaining both sides relation using this method, in can detecting its application at the scene, using in the supposition of site infrare testing result
The actual temp value of portion's hot localised points, to provide accurate analysis for the state of equipment.
