Vehicle Data Transmission Prioritization via Dual-Server Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle data transmission systems fail to quickly and accurately transmit emergency data during critical situations due to inefficient prioritization and data management, leading to delayed emergency responses.
Innovation Solution
A system and method that utilize two servers and a vehicle to dynamically prioritize data transmission based on emergency levels, waiting time, frequency, and current traffic conditions, ensuring timely and efficient transmission of accident, failure, diagnosis, and driving data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted without priority-based differentiation, then all data including emergency data is transmitted, but emergency data transmission is delayed due to sequential processing and network traffic
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different types of data. Emergency data is assigned high priority while other data types receive lower priorities. This differentiation ensures that emergency data receives preferential treatment in terms of transmission resources and timing, resolving the contradiction between reliable emergency transmission and timely response.
Solution Approach 2:
The system implements feedback mechanisms where the server receives data from vehicles, determines priorities based on data type and emergency level, and adjusts transmission scheduling accordingly. This feedback loop enables dynamic priority assignment that responds to real-time conditions, ensuring emergency data is transmitted promptly while maintaining overall system efficiency.
2Productivity
If massive data such as image contents and camera data is transmitted first, then data transmission block is filled quickly, but emergency data transmission is delayed or postponed
Solution Approach 1:
The patent differentiates data transmission quality by priority level. Instead of treating all data equally, the system assigns high priority to emergency data and lower priority to non-critical data such as image contents and camera data. This ensures that even when the transmission block is full, emergency data can displace or be transmitted ahead of lower-priority data, preventing delays in critical situations.
Solution Approach 2:
The server acts as an intermediary that mediates between data generation at vehicles and data transmission to the control center. It implements priority-based scheduling and can hold or queue non-emergency data while prioritizing emergency data transmission. This intermediary function resolves the conflict between maintaining high throughput and ensuring timely emergency data delivery.
3Ease of operation
If data transmission priority is determined only by storage order, then first stored data is transmitted first, but emergency data stored later cannot be transmitted quickly
Solution Approach 1:
The patent changes the priority parameter from simple storage order to a composite parameter that includes data type, emergency level, and timing. The server evaluates multiple parameters to determine transmission priority, allowing later-stored emergency data to be assigned high priority and transmitted immediately. This parameter transformation maintains operational simplicity while dramatically improving emergency data transmission reliability.
Solution Approach 2:
The system implements dynamic priority assignment where transmission priorities are not fixed but adjusted based on data characteristics and system conditions. Emergency data automatically receives elevated priority regardless of when it was stored. This dynamic approach ensures that simplicity of operation does not compromise emergency response reliability.

AI summary
A system and a method are provided for transmitting data of a vehicle for efficiently managing a server or a communications network by at least a communications network infrastructure by determining a first list of priorities of vehicle information by a second server, transmitting the first list of priorities to a first server, comparing the transmitted first list of priorities of the vehicle information with traffic data to generate a second list of priority information, and informing the second server and a computing device of the vehicle of the generated second list of priority information.
