In view of the difficulty of accurate measurement and real-time analysis of the electrical transport properties of materials under continuous temperature change conditions, a real-time measurement and analysis system based on LabVIEW 8.6 for electrical properties of materials is designed. The system first selected high-precision current and voltage meter as the main measurement components, high-precision temperature controller and compressor as the control of the material to change the ambient temperature components, and then use the Labview 8.6 programming flexibility, intuitive interface features designed to real-time acquisition And processing data of high-precision material transport performance measurement software system, visual display of materials in different environments, the characteristics of the transport of electricity and save the measured data in real time. Through testing the characteristics of the two materials, it shows that the system has the ability of rapid data acquisition and processing, high precision measurement ability, and avoid the shortcomings of artificial measurement method can not process and analyze data in real time. It provides the measurement of electrical transport properties A new program, while providing a reference for the design of high-performance electronic devices.
