Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to detect approaching flying vehicles when they switch between terrestrial and satellite communication, leading to potential collisions due to communication gaps.
Innovation Solution
An information processing apparatus and method that assesses the need to switch communication modes based on radio signal strength, adjusting detection ranges accordingly to ensure continuous detection of nearby vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection range is kept small for normal operation, then the system operates efficiently with reduced processing load, but the system cannot detect approaching flying vehicles during communication mode switching
Solution Approach 1:
The detection range is made dynamic rather than static. The determination unit adjusts the detection range based on the assessment of communication mode switching requirements. When switching is anticipated, the detection range is enlarged; when switching is not required, the detection range returns to normal size. This dynamic adjustment resolves the contradiction by adapting the detection range to operational conditions.
Solution Approach 2:
The system performs preliminary assessment of whether communication mode switching will be required before the actual switching occurs. By assessing in advance whether the flying vehicle is in a region where radio signal strength may drop below thresholds, the system can proactively enlarge the detection range before communication interruption happens, ensuring continuous detection capability.
2Reliability
If the detection range is enlarged to ensure detection during communication switching, then detection reliability improves, but the processing load and system complexity increase
Solution Approach 1:
The assessment unit performs preliminary evaluation of communication conditions using pre-stored threshold values and radio signal strength data. This advance assessment allows the system to prepare for detection range adjustment without waiting for actual communication failure, reducing reactive processing time and improving overall response efficiency.
Solution Approach 2:
The system uses its own existing data (radio signal strength measurements and threshold values) to perform self-assessment of communication conditions. This self-service approach eliminates the need for external assessment systems, reducing overall system complexity and processing overhead while maintaining reliable detection.
3Reliability
If communication mode switching is performed based on radio signal strength thresholds, then communication reliability improves, but detection capability may be lost during the switching transition
Solution Approach 1:
The system assesses whether communication mode switching will be required before the switching occurs, based on current radio signal strength and threshold comparisons. This preliminary action allows the determination unit to proactively enlarge the detection range in advance, ensuring that detection capability is maintained throughout the communication transition period without information loss.
Solution Approach 2:
By enlarging the detection range before communication mode switching occurs, the system creates a buffer or cushion that ensures continuous detection capability during the vulnerable transition period. This beforehand cushioning compensates for the potential detection gap that would otherwise occur during communication switching.

AI summary
A flight management server having an assessment unit that assesses whether or not there will be a requirement to switch communication performed by a first flying vehicle during flight between terrestrial communication and satellite communication; and a determination unit that determines a detection range for providing a report in response to detection of a second flying vehicle different from the first flying vehicle, the detection range being defined with respect to a position of the first flying vehicle; wherein the determination unit makes the detection range for a case in which the assessment unit has assessed that there will be a requirement to switch between the terrestrial communication and the satellite communication larger than the detection range for a case in which the assessment unit has assessed that there will be no requirement to switch between the terrestrial communication and the satellite communication.
