8 DSO - Device
diagnostic Synchronous Oversampling system
8.1
Implementing 50us data acquisition through PLC
DSO - Device diagnostic Synchronous Oversampling system is based on PDA system. PDA system supports data acquisition of 50 kHz and 0.02 ms sampling period, the full historical data are stored, the real-time FFT calculation and curve analysis are supported, flexible and continuous time slice may be selected, the special AD converter board and special storage system may be used, the standard PLC system is also used to complete signal access and quickly realize system deployment. The over sampling AI module of PLC system can realize the sampling rate of 16KHz, 20kHz, etc., which can meet the access of acceleration sensor, speed sensor, displacement sensor, etc. in the equipment diagnosis system. At the same time, the process data such as speed, current, pressure, flow, temperature and other conventional acquisition cycle signals can also be accurately and synchronously collected, avoiding the complicated offline alignment work in the later stage. The system is simple and transparent, online and offline data can be directly connected to the diagnostic analysis system, and the calculation results can be obtained immediately, supporting 2 million spectral lines.

Implementing 50us data acquisition through PCIe card
It can synchronously collect 16 channel signals with a resolution of 16 bits. The data acquisition card is inserted into the PCIe slot of the computer, and the PDAServer collects real-time data from 16 channels every 50us. The real-time data is used for real-time analysis and efficiently compressed into. dat data files for offline analysis.

Realize 50us data acquisition through USB or Ethernet interface
board
It can synchronously collect signals from 18 channels with a resolution of 16 bits. The CPU in the interface board performs high-speed synchronous acquisition of data from the 18 channels and stores it in the memory buffer. Every millisecond, the data in the buffer is sent to the PDA computer via a USB cable or Ethernet. The PDA Server parses the data from each channel according to the data storage convention in the buffer for real-time analysis and compresses it throughout the process into an offline .dat data file. The number of channels can be reduced or expanded, and the sampling period can also be adjusted.
