(4), it is part critically important in method of testing that the temperature data recorded is shown, but existing temperature
The display packing of data, majority is all to transfer data to near-end display device show, can only meet
The change situation of the temperature data that Field Force's research records, but but can not realize transferring data to remotely
Monitoring center carry out the function that shows.(5) existing measuring technology based on Infrared Thermography Technology, records
Temperature, simply with the display of temperature cloud picture, is not carried out post processing and becomes the temperature with contour by data
Cloud atlas, it has not been convenient to the surface temperature rise situation being devices under is differentiated and studied to testing crew clearly.
