Mini-Data Acquisition System for Small-Scale Wave Energy Testing

Data acquisition (DAQ) systems are a necessary component for products whose outcomes depend on collected information throughout its operation. Current systems are directed towards large companies utilizing custom hardware, software, and requiring its user to have high-level skills in coding and system setup; but with the increasing interest in renewable energy, small corporations, university research departments, and independent companies are undergoing their own testing, requiring DAQ systems on a smaller scale. The purpose of this project was to produce an easy-to-use EtherCAT server DAQ system alternative, aimed towards new developers conducting small scale testing in the wave energy field. This report serves to outline the product made in the Mini-Data Acquisition (miniDAQ) project funded by Sandia National Laboratories. Along with various sensors such as encoders, analog-to-digital converters, and an inertial measurement unit, the miniDAQ contained an A! rduino Mega 2560 Rev3 as the development board, equipped with AB\&T's EasyCAT shield as a means to operate in real-time through the protocol EtherCAT when combined with real-time systems SpeedGoat and Mathworks Simulink. This setup met the main requirements of real-time operation, 100 Hz sampling frequency, differential inputs/outputs, and two communication interfaces.
