【Abstract】 This paper introduces the principle of Barkhausen noise. Based on the in-depth study of Barkhausen noise method and analysis, a detection system on the basis of Barkhausen noise stress was proposed. In this system,the overall construction of the exciting signal generation,data sampling, data processing and host controller interface parts was based on the industrial PC. It combines Barkhausen noise stress testing technology with data signal processing technology, and provides convenient man-machine interactive interface. This paper emphatically expounds the design scheme of stress testing equipment, which includes the design of the hardware module function and that of human-computer interaction interface. The experimental results show that the equipment performance is stable,and it has high measurement accuracy. The application prospect is very broad.更多还原
