DFT6000Natural frequency acquisition and analysis system software

DFT6000The signal analysis system supports two working states simultaneously: signal acquisition and post-processing analysis,This system has the following characteristics:

1. The entire system adoptsC++Language development, object-oriented programming, fully plugin architecture, system stability, reliability, and strong scalability.

2. The system supports both online mode and post-processing mode, with the option to switch between the two modes. It also supports workspace and project document management functions, making data management very convenient.

3. Support virtualTEDSSensors are managed uniformly using a database, making them more convenient to use.

4. Simultaneously supporting multiple languages, the system defaults to supporting both Chinese and English. The language files are in text format, and users can translate them according to their actual needs to ensure good support for other languages. Different languages can be switched in real-time.

5. It can be equipped with various signal analysis instruments produced by our company, and the type of analyzer can be specified according to the actual product used by the user.

6. It has rich multiple parameter setting functions:

l The sampling start and end channels can be set arbitrarily;

l Randomly specify whether each sampling channel is saved or not;

l Can adjust the refresh rate of graphics when displaying waveforms;

7. Supports multiple file storage formats. The file format for saving can be the binary format exclusively used by Lianneng Company, or it can be saved asUFF58TheUFF58b，MatLab5.0format,Convenient for users to analyze data using other software.

8. Multiple sampling methods:

l Oscilloscope mode;

l Manually triggered;

l Signal triggering;

l Continuous recording.

9. It has rich time-domain and frequency-domain analysis and processing functions, and the system supports displaying:

l Strain flower calculation

l Single trace oscilloscope view;

l Multi track time-domain waveform;

l Li Shayutu (i.eX-YFigure,XAxis,YThe axis can specify any channel);

l Fourier analysis;

l Self spectral, power spectral, and power spectral density analysis;

l Transfer Function Analysis;

l Analysis of rotational speed of rotating machinery;

l statistical information(It can display the maximum and minimum values, peak to peak value, effective value, variance, standard deviation, peak factor, waveform factor, pulse factor, and margin factor of any number of channels).

10. Make full use of the computer's massive storage hard drive to record multi-channel signals for a long time, in real-time, and without interruption.
