Design and Realization of Intelligent Electrical Resistivity Measurement System

Abstract:

Based on graphic program language LabVIEW and Micro Control Unit MSP430F169, an intelligent electrical resistivity measurement system with four-point probe and four-line was studied in this paper. Structured Query Language of LabVIEW was applied for calibration and management in database. Hardware feedback and software compensation technologies were designed in high-precision current source, whose range was automatic selected in auto-mode. Between the computer program and hardware control unit controlled by MCU, a RS-232 data communication protocol was applied in order to improve the ability of human-machine interaction and automation degree. Experiment results in semiconductor and metal material science indicated that the measurement system measured accurately and automotive, the information database of the tested material was the foundation of data analyzing and data mining.
