A vision inspection system with correlated high speed underwater cRIO based magnetic field data with motion control for a SubSea mooring line inspection system.
An NI Vision solution for visual inspection with cRIO for high speed data capture for SubSea mooring line inspection. A fiber link transmits all of the high speed video and sensor data to the surface for control, monitoring and logging. An embedded FPGA / cRIO application is used to capture high speed magnetic sensors at 250KHz using multiplexed high speed analog and digital switching. We also developed motion controlled stepper motors and feedback sensors for tracking the motion, with additional parameters for pressure and geometry data. Everything is presented visually in real time to the operator at the surface, using a LabVIEW application for viewing and inspecting the data both in real time and for post job playback and analysis.
