Abstract


Emissivity is to describe the parameters of the object emitting ability , also known as emissivity , the parameter of the reaction heat radiation exchange between the objects and the object surface temperature characteristics has important application value . The emissivity of the material surface is not intrinsic characteristics of the material , the temperature of the material , the composition , and measuring the state of the surface material , a number of factors such as the measurement direction , and thus to realize the surface state of change accurate measurement of emissivity to design a high-precision line measurement system has a very important significance. Based on the actual needs of the system studied by comparing a variety of existing induction emissivity measurement methods to determine the method based on blackbody radiation conversion rate measurement principle and the measurement principle for a more in-depth analysis and discussion. Paper describes the thermal radiation line measurement system software design electronic parts of the system functional requirements and performance indicators , and so a detailed description of the software design process , and developed a computer to communicate with the communication protocol. Articles of the information processing section is used by the compensation algorithm for a more comprehensive analysis algorithm model focuses on the establishment of the method and process data through the preprocessing, compensation algorithm processing , the correction processing procedure to obtain a final measurement result , where compensated access is the key algorithm model is difficult , using a combination of theoretical derivation method for testing the model parameters and, finally, a complete set of mathematical models . Confirmatory tests confirmed through an electronic system designed software is stable and reliable data processing model obtained feasible and effective , long-lasting resistance to meet the measurement requirements , can enter the practical stage .
