  • ACEP at Work: VDOS Project Logbook – Weekly Update

Project Description:  ACEP’s Video Debris Observation System (VDOS) project consists of designing, constructing, and testing of a rugged remote video observation system to detect river debris with the goal of protecting hydrokinetic turbines. It will be used to monitor surface debris, typically floating logs, at the AHERC Tanana River Test Site to determine the frequency of debris and monitor its interaction with the AHERC Research Debris Diversion Platform.

Progress Update:  Final setup of the video system was completed. Images are now storing correctly on the NAS device and both cameras are configured to take time interval photos. A short test of the system was completed and everything performed as desired. A longer test will be conducted once the other system on the test stand (the BlackBox) is ready for testing since they are both running off the same power supply. Additionally an as-built circuit diagram was created showing components and sizing along with installed wire numbers.
