Moving Body Data Transmission Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for moving bodies, such as drones and autonomous vehicles, do not prioritize data transmission effectively, leading to inefficiencies in determining successful movement and the need for re-imaging, especially when communication bandwidth is limited.
Innovation Solution
A moving body with a control unit that sets processing priorities for acquired data and a communication unit that transmits data based on these priorities, ensuring that critical images are transmitted preferentially, especially when near target signals, to facilitate timely topographical surveys and inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted uniformly without priority setting, then all data can be transmitted, but transmission efficiency is reduced and critical data cannot be delivered timely
Solution Approach 1:
The patent segments data into different priority levels (first priority for critical data like images indicating movement failure, second priority for other data). The control unit classifies acquired data into these priority categories, enabling differentiated transmission handling where high-priority data is transmitted immediately while lower-priority data can be delayed or buffered.
Solution Approach 2:
The patent applies local quality by assigning different transmission qualities to different data packets based on their priority classification. Critical data receiving first priority gets preferential treatment in terms of transmission timing and resource allocation, while non-critical data receives standard or delayed transmission, optimizing overall system performance for the most important information.
2Loss of information
If all acquired data is transmitted, then complete information is provided, but communication bandwidth is consumed inefficiently
Solution Approach 1:
The patent implements partial action by selectively transmitting only the most critical data (first priority) when communication resources are limited or bandwidth is narrow. The control unit determines that transmitting a subset of high-priority data is more valuable than transmitting all data uniformly, especially in scenarios where quick determination of movement success is needed and re-transmission would be costly.
Solution Approach 2:
The control unit performs preliminary classification and prioritization of data before transmission. By pre-identifying which data packets are critical (such as images showing movement failure) and assigning them first priority, the system prepares transmission queues in advance, ensuring that bandwidth is allocated efficiently to the most important information first.
