Solution Overview
Problem
Real-Time Kinematic (RTK) positioning systems require frequent data updates for high accuracy, leading to significant power drain in devices, posing logistical challenges for applications like drone delivery and autonomous vehicles that need precision while managing battery life.
Innovation Solution
A computerized power management framework that analyzes device characteristics such as movement, battery level, and signal strength to optimize RTK update rates, reducing unnecessary power consumption by adjusting update frequencies and enabling power-saving modes, such as grouping devices and throttling RTK updates based on movement and battery levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RTK data updates are performed frequently to maintain high positioning accuracy, then positioning precision is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the RTK data update frequency based on real-time device movement characteristics. When the device is stationary or moving slowly, update frequency is reduced to conserve power. When movement exceeds thresholds, update frequency increases to maintain positioning accuracy, thus resolving the contradiction between continuous high-accuracy positioning and power consumption
Solution Approach 2:
The system changes the parameter of data update frequency based on device state. By monitoring movement parameters and battery level, the system adjusts the RTK update interval parameter dynamically - using lower update frequencies when precision requirements are temporarily reduced and higher frequencies when precision is critical, thereby optimizing the balance between accuracy and power usage
2Reliability
If RTK update frequency is increased to maintain positioning accuracy during movement, then positioning reliability is improved, but battery life deteriorates
Solution Approach 1:
The system implements periodic monitoring of device movement and battery status, adjusting RTK update frequency in periodic intervals rather than continuously. This allows the system to maintain positioning reliability during critical periods while conserving battery life during stable periods, resolving the contradiction between continuous high-reliability positioning and extended battery operation
Solution Approach 2:
The system applies partial RTK updates rather than continuous full-frequency updates. By determining that full update frequency is only necessary during specific movement conditions or when positioning reliability is critical, the system uses reduced update frequency during stable conditions, thus extending battery life while maintaining adequate positioning reliability when needed
