 Sampling mode

Acquisition and calculation

Signal preprocessing

Synchronous whole period sampling

Synchronous fixed frequency sampling

Over-sampling

Sampling triggered by overrun of specific parameters

Eigenvalue calculation and extraction

FFT calculation

Real time data saving

Upload the original waveform and static characteristic value to the server database at preset time intervals

Save historical data

Save historical data value server database according to preset rules

Save abnormal data

Save the real-time data in a period of time before and after the abnormal state occurs to the server abnormal database

Data local cache

When the network is interrupted, the data is stored in the local buffer memory of the collector;

After the network resumes communication, the data is continuously transmitted to the server database

Key technical indexes

4 monitoring modules, each of which contains 5 vibration channels and 1 key phase

Two-way speed monitoring

Sampling frequency: 100ksp / channel
