Data Acquisition

The OpenPMU data acquisition module is built on the BeagleBone Black platform and provides time synchronised sampled values for use in phasor estimation algorithms.  The key benefits are that the sampled values are accurately timed, evenly spaced, and presented in an easy to use XML datagram.  

Detailed information is available through the open access publication below.

The Data Acquisition module features:
  • Small number of external components
  • Open source hardware design
  • Uses low cost BeagleBone Black (BBB) development board
  • Low Power
  • Real-time Servo Clock
  • Real-time Data Acquisition
  • Sampled Values via Ethernet
  • OpenPMU XML schema
