Mesh Region Data Distribution for Mobile Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information management systems face challenges in efficiently managing uploaded information from mobile objects, such as vehicles, by accurately associating position information with mesh regions on maps, especially when the regions change between sampling times, leading to difficulties in distributing and storing data effectively.
Innovation Solution
An information management device and method that acquires uploaded information from mobile objects, generates mesh information based on position data, and stores it in association with defined mesh regions, distributing data proportionally across adjacent regions when necessary, and classifying regions based on connection patterns to optimize data management and provide user-relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uploaded information is associated with position information and stored in mesh regions, then information management accuracy is improved, but computational load increases when distributing data across multiple regions
Solution Approach 1:
The ground region is divided into multiple mesh regions with unique identifiers, allowing position information to be segmented and stored in appropriate regions. This segmentation enables precise location tracking while distributing the data storage burden across multiple manageable units rather than requiring complex centralized processing.
Solution Approach 2:
Mesh information is generated and stored locally in each mesh region based on uploaded information from mobile objects. Each region maintains its own data independently, allowing local processing and reducing the need for complex inter-region computational coordination, thereby lowering overall computational load.
2Productivity
If mesh regions are defined to delimit ground region, then data organization efficiency is improved, but difficulty in distributing information across adjacent regions increases
Solution Approach 1:
The ground region is segmented into discrete mesh regions with unique identifiers, creating a structured grid system. This segmentation provides clear boundaries for data organization while enabling systematic distribution rules based on region adjacency and proportional relationships, simplifying the distribution process.
Solution Approach 2:
When distributing uploaded information across mesh regions, the system uses proportional distribution based on parameters such as the degree of overlap between regions and the position of the mobile object. By changing from binary inclusion to proportional parameter-based distribution, the system handles adjacent regions more efficiently.
3Loss of time
If uploaded information represents events between sampling times, then temporal information coverage is improved, but accuracy of associating information with specific mesh regions decreases
Solution Approach 1:
The system performs preliminary identification of the mesh region containing the mobile object at the first sampling time before distributing information. By establishing the initial region association in advance, the system can then proportionally distribute event information to adjacent regions based on predetermined spatial relationships, maintaining both temporal coverage and spatial accuracy.
Solution Approach 2:
The system uses proportional distribution parameters to allocate uploaded information between the first mesh region and adjacent regions based on the temporal duration and spatial extent of the event. By applying parameter-based proportional allocation, the system accurately attributes temporal events to specific regions even when the mobile object crosses boundaries between sampling intervals.
