Flying Vehicle Communication Switching Safety Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flying vehicles face safety risks when switching between terrestrial and satellite communication due to potential proximity to objects without accurate positional recognition during communication switching periods.
Innovation Solution
An information processing apparatus with an assessment unit and switching control unit that determines a detection range and controls communication switching between terrestrial and satellite communication based on the presence of objects within that range, using position, scheduled flight, and radio signal strength information to ensure safe communication switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flying vehicle switches between terrestrial and satellite communication, then communication reliability is improved, but safety deteriorates due to potential proximity to objects during switching
Solution Approach 1:
The assessment unit performs preliminary assessment before communication switching by determining whether an object exists within a detection range calculated from the current position and switching time. This preliminary action prevents unsafe switching by evaluating environmental conditions in advance, ensuring that switching only occurs when no objects are present in the potential conflict zone.
2Object-affected harmful factors
If the detection range is enlarged to ensure safety, then safety is improved, but communication switching frequency is reduced
Solution Approach 1:
The detection range is dynamically calculated based on real-time position information and the estimated switching time. The range is defined as the distance the flying vehicle can travel during the communication switching period, creating a time-dependent safety zone. This dynamic approach ensures adequate safety margin while allowing frequent switching when the environment is clear.
3Measurement precision
If position information accuracy is improved, then communication switching safety is improved, but system complexity increases
Solution Approach 1:
The patent uses an intermediary assessment unit that mediates between position information acquisition and communication switching control. This intermediary component processes position data, calculates detection ranges, and evaluates object presence before triggering switching. The assessment unit simplifies the overall system by centralizing the safety evaluation logic rather than requiring complex integrated control.

AI summary
A flight management server having an assessment unit that assesses whether or not there is an object different from a flying vehicle within a detection range defined with respect to a position of the flying vehicle during flight; and a switching control unit that controls switching of communication performed by the flying vehicle during flight between terrestrial communication using terrestrial communication equipment and satellite communication using a communication satellite on the condition that the assessment unit has assessed that the object is not within the detection range.
