traditional instruments;  virtual instruments;  LabVIEW development platform;  Experiment networking

In view of the shortcomings of the closed nature of traditional instruments and the difficulty of function expansion, a set of networked signal analysis and data processing experimental benches based on virtual instruments are designed with LabVIEW as the development platform. The experiment is completed on the simulated rotor test bench, and the corresponding sensors and measuring instruments are configured according to the needs to realize the acquisition of engineering signals, and then the processing, display and printing of the collected data are realized in the developed signal analysis software, and HUB and multiple terminal displays can be configured, and a small LAN can be established, and finally the experimental test network can be realized.
