【Abstract】 An SRM(switched reluctance motor)real-time online monitoring system based on virtual instrument is designed based on LabVIEW and analog acquisition card. In this system,the motor phase current,bus voltage,torque,rotate speed and other variants are captured and filtered,and the signal is collected at a high sampling rate and transmitted to the upper computer quickly by means of the analog acquisition card,so as to display signal waveform in real time and save data on the LabVIEW interface of the upper computer. The experimental results show that the monitoring system has the characteristics of high acquisition frequency,fast communication between upper and lower computers,flexible system structure and good stability.It can be used to monitor the SRM speed regulation control system with high dynamic response,and record and monitor the transient process of the motor in real time.更多还原
