Design of magnetoacoustic emission stress detection system based on FPGA and Lab VIEW
Magnetoacoustic emission(MAE)is an effective method for stress detection.Aiming at the problems of fixed design parameters and poor flexibility of traditional detection instruments,a magnetoacoustic emission stress detection system with adjustable parameters was designed by using FPGA and Lab VIEW.Among them,the FPGA was responsible for generating waveform of the excitation signal,and sent the received AD conversion data to the host computer for processing.LabVIEW host computer program was responsible for signal reception,data processing and storage.The experimental results showed that the designed detection system was simple,reliable,highly integrated,and can flexibly adjust the excitation signal to meet the demand of stress detection.
