Geomagnetic Information Update via Terminal Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for updating geomagnetic information are inefficient as they require manual re-collection of data each time the information changes, leading to low update efficiency.
Innovation Solution
A method where a terminal transmits real-time geomagnetic and location assistance information to a server, which determines if the corresponding geographical location's information is invalid and updates it automatically in a prestored correspondence, eliminating the need for manual re-collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual re-collection of geomagnetic information is performed each time the information changes, then the accuracy of geomagnetic information can be maintained, but the update efficiency becomes low
Solution Approach 1:
The terminal automatically performs geomagnetic information collection and transmission during normal positioning operations, eliminating the need for manual technician intervention. The system self-updates by utilizing the terminal's own sensing capabilities and communication functions, thereby maintaining accuracy while significantly improving update efficiency
Solution Approach 2:
The server receives geomagnetic information from the terminal and automatically updates the correspondence when changes are detected. This feedback mechanism ensures that accurate geomagnetic information is maintained through continuous monitoring and automatic updates based on real-time data from the terminal
2Reliability
If manual re-collection of geomagnetic information is performed, then updated information can be obtained, but time consumption increases
Solution Approach 1:
The terminal continuously collects and transmits geomagnetic information during normal positioning operations before manual updates are needed. This preliminary action ensures that updated information is already available in the server's correspondence, eliminating the time delay associated with manual re-collection when information validity needs to be maintained
3Productivity
If automatic update method is implemented, then update efficiency is improved, but system complexity increases
Solution Approach 1:
The terminal utilizes its existing positioning and sensing functions to simultaneously perform geomagnetic information collection, validation, and transmission. By making the terminal multi-functional, the system achieves automatic updates without adding significant complexity, as the terminal already possesses the necessary hardware and software capabilities for these additional functions
