Title:
OPERATION ASSISTANCE SYSTEM AND OPERATION ASSISTANCE METHOD FOR UNMANNED AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2023/238350
Kind Code:
A1
Abstract:
The present invention efficiently acquires local wind conditions to safely operate an unmanned aircraft. This operation assistance system for unmanned aircraft is configured using an optical analysis unit, an information processing device, and a communication device that wirelessly communicates with an unmanned aircraft. This operation assistance system acquires the current wind conditions in the span of a power transmission line or distribution line on the basis of the vibration state acquired by distributed acoustic sensing (DAS) at measurement points set along an optical fiber installed along the power transmission line or distribution line, generates a flight plan on the basis of the acquired wind conditions, and transmits the generated flight plan or flight control instructions based on the flight plan to the unmanned aircraft. This operation assistance system also acquires forecast values of weather information in the area where the unmanned aircraft is scheduled to fly, which are provided by a weather information provider, and predicts future wind conditions in the span by correcting future forecast values on the basis of the correlation between the time-series data of the forecast values and the time-series data of the wind conditions in the span.
