Drone Position Guidance for Reliable Image Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
General mobile communication systems have poor communication quality for drones flying at heights of 50 to 120 meters, leading to issues with transmitting image data due to the weak radio wave signals emitted by base stations, and existing systems do not provide position information for optimal data transmission spots.
Innovation Solution
A system that stores position information and corresponding communication rates, allowing for the extraction and output of positions with suitable communication rates for data transmission, enabling drones to fly to areas with better signal quality and transmit image data effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations emit main lobe toward the ground for mobile communication, then communication quality for ground terminals is improved, but communication quality for drones at 50-120m height deteriorates
Solution Approach 1:
The operation control station performs preliminary actions by storing position information and communication rates in advance, and notifying the drone of positions with adequate communication rates before the drone reaches them, enabling the drone to proactively navigate to optimal communication zones
Solution Approach 2:
The operation control station acts as an intermediary between the base station and the drone, receiving communication rate information from base stations and relaying position information to the drone, thereby bridging the information gap that causes poor communication quality
2Device complexity
If the operation control station only transmits control messages without position information, then system complexity is reduced, but the drone's ability to transmit image data deteriorates
Solution Approach 1:
The operation control station performs preliminary action by notifying the drone of positions with adequate communication rates before the drone needs to transmit image data, allowing the drone to proactively navigate to optimal transmission locations
Solution Approach 2:
The system implements feedback by the drone reporting its current position to the operation control station, which then compares the reported position with stored position information to determine and communicate optimal transmission positions back to the drone

AI summary
In order to solve the problem in which a flight vehicle flies only in locations having poor communication quality and retained data cannot necessarily reach the ground, this device communicates with a flight vehicle, wherein the device is provided with: a storage means that associates and stores first position information and a first communication rate at which it is possible to communicate at the position of the first position information; an extraction means that, upon receiving information that corresponds to a prescribed second communication rate at which the flight vehicle transmits data, extracts the first position information corresponding to the first communication rate equal to or greater than the second communication rate from the storage means; and an output means that outputs the first position information extracted by the extraction means to the flight vehicle, or outputs the inputted first position information to an instrument that notifies the flight vehicle.
