DESCRIPTION

2014 PV Reliability, Operations & Maintenance Workshop: HelioSpec by DreamQii: High resolution UAV system monitoring HelioSpec, Rob Andrews

TRANSCRIPT

  • 1. HelioSpec by DreamQii: High resolution UAV system monitoring Rob Andrews May 7,2014 Rob.Andrews@heliospec.com www.heliospec.ca

2. Helio Spec Built on the DreamQii UAV platform Multiple drone (Swarm) operation Pre-programmed flight paths with flight simulation Integrated obstacle avoidance Low cost, modular construction Operator can control multiple drones at once Manual override, Return to land, emergency abort Redundant fail safes Mission: Create a practical tool for the PV specialist who learns to fly a drone, not the drone specialist who learns to inspect PV 3. The HelioSpec swarm Utilize multiple low cost units to efficiently cover large areas at high resolution Communicate with other drones and robotic systems 4. Workflow Site visit Pre-Flight and Swarm Launch Data Capture and Navigation Real Time Processing Corrective Actions Long Term analysis and trend reporting Data transfer to cloud Receive processed data on-site 5. Enterprise Workflow Designed for low enterprise overhead HelioSpec manages: Pilot training Flight path creation and optimization System maintenance, parts replacement Image processing and distribution Regulatory compliance (Eg: SOFC permits in Canada) Billed on pay-per-use basis: low capital overhead 6. Why UAV Inspection? Cover large sites quickly ~15 minutes per scan Create a system fingerprint Thermal normalization of large sites Optimal imaging angles Observe and diagnose: Solder Bond Failure Diode Failure Loose connections Potential Induced Degradation (PID) Cracks and micro-cracks Soiling distribution (Multi- sensor) Accelerated degradation Poor inspection angle from ground perspective shows sky reflection artifacts Two Short-circuited Modules 7. What is a module failure? Source: Mani Tamizhmani , TUV 8. Regulations- Canada Low altitude,
