Dynamic Positioning Trigger Conditions for Terminal Track Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current movement track recording methods in terminal devices consume excessive power due to fixed and small positioning intervals, affecting battery life without ensuring precision.
Innovation Solution
A method that dynamically adjusts positioning trigger conditions based on positioning precision, movement status, and location environment, using GPS, WiFi, or cell identity positioning, and sets adjustable positioning time intervals and geo-fence boundaries to reduce power consumption while maintaining track recording precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a relatively small fixed period is used for positioning to ensure track recording precision, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The patent applies dynamics by transforming the fixed positioning interval into a dynamic, adjustable interval. The system automatically adjusts the positioning time interval based on movement status (moving vs. stationary) and location environment (indoor vs. outdoor), allowing shorter intervals when precision is critical and longer intervals when power saving is prioritized, thus resolving the contradiction between measurement precision and energy consumption
Solution Approach 2:
The patent changes the parameter of positioning time interval from a fixed value to a variable parameter that adapts to different conditions. By modifying this parameter based on movement status and environment type, the system achieves optimal balance between track recording precision and power consumption across various scenarios
2Ease of operation
If a fixed positioning interval is used, then ease of operation is improved, but adaptability decreases
Solution Approach 1:
The system implements self-service by automatically detecting movement status and location environment, then autonomously adjusting the positioning time interval without user intervention. This maintains ease of operation while achieving high adaptability to different scenarios through automatic parameter optimization
3Measurement precision
If positioning is performed frequently to ensure accurate track recording, then measurement precision is improved, but duration of action decreases
Solution Approach 1:
The patent extends battery life by making the positioning frequency dynamic rather than fixed. The system adjusts positioning frequency based on actual needs (movement status and environment), performing positioning frequently only when necessary for precision while reducing frequency during stationary periods or in environments where lower precision is acceptable, thus extending operational duration
