Fleet Vehicle Data Upload Control by Random Transmission Probability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to efficiently transmit data from only a subset of a transportation vehicle fleet to a back-end system, as they do not provide a solution for selectively sending data from part of the fleet.
Innovation Solution
A method where transportation vehicles receive a message with information about data to be transmitted and a predetermined probability of transmission, using a random generator to determine whether to send the data to a data processing system, allowing for adjustment of the number or proportion of vehicles sending data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all transportation vehicles in the fleet transmit data to the data processing system, then the data processing system receives comprehensive data from the entire fleet, but the data transmission volume and network load increase significantly
Solution Approach 1:
The patent applies partial action by having only a subset of transportation vehicles transmit data to the backend system. Instead of requiring all vehicles to send data, the system selectively transmits data from a portion of the fleet, reducing overall transmission volume while maintaining sufficient data availability for backend processing and analysis.
2Productivity
If a fixed number of vehicles are required to send data, then the backend receives consistent data volume, but the system lacks flexibility in adapting to different operational conditions
Solution Approach 1:
The system implements dynamic adaptability by allowing the proportion of vehicles transmitting data to vary based on operational conditions, backend requirements, and fleet status. The selection mechanism can adjust the number and proportion of transmitting vehicles dynamically, enabling the system to optimize data collection efficiency while adapting to changing operational contexts and backend processing capabilities.
3Device complexity
If random selection is used to determine which vehicles transmit data, then the system achieves simplicity and reduces complexity, but may result in inconsistent data coverage over time
Solution Approach 1:
The system incorporates feedback mechanisms where the backend data processing system can communicate requirements back to the fleet, and vehicles can report their status and transmission history. This feedback loop allows the system to monitor data coverage quality and adjust the random selection parameters accordingly, ensuring consistent data coverage while maintaining the simplicity of random selection for determining which vehicles transmit.
