Magnetic suspension real-time signal monitoring system and method based on Ethernet and virtual instrument

The invention belongs to the technical field of magnetic suspension control systems, and discloses a magnetic suspension real-time signal monitoring system and method based on the Ethernet and a virtual instrument. The system comprises a displacement sensor, an AD module, an Ethernet communication module, and a client program. According to the invention, a sampling system of the magnetic suspension control system is utilized, a W5300 module and LabView virtual instrument software are matched, five-degree-of-freedom vibration signals and control current signals of the magnetic suspension rotor are monitored in real time without the help of any external test instrument, expensive equipment such as an oscilloscope and a data acquisition card is omitted, the development cost is reduced, and meanwhile, interference caused by long-distance transmission of analog signals is avoided. The real-time performance of signal monitoring of the magnetic suspension system is enhanced, and meanwhile, multiple data processing f
