Receiver Antenna Switching for Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-polling radio frequency receivers lack the capability to efficiently switch and power multiple antennas, leading to increased processor load and power consumption in vehicle applications where multiple signals need to be received.
Innovation Solution
A system and method for a receiver with antenna switching capability, utilizing a micro-processor to coordinate power distribution to multiple antennas, allowing for selective activation and deactivation of antennas based on signal polling requirements, implemented with a processor circuit, receiver circuit, and power switching circuit, enabling efficient power management and reduced processor load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are continuously powered to receive different RF signals, then signal reception capability is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches antenna power states based on polling requirements. The receiver controller activates power to specific antennas only when they need to be polled for RF signals, and deactivates power when not needed. This dynamic power management allows the system to maintain multi-antenna signal reception capability while significantly reducing average power consumption compared to continuous powering.
2Ease of operation
If a micro-processor switches antennas manually, then antenna control is achieved, but processor load increases
Solution Approach 1:
The receiver controller autonomously manages antenna switching and power distribution without requiring manual micro-processor intervention. The controller self-determines which antennas need to be polled and automatically activates/deactivates power to appropriate antennas, freeing the micro-processor from this task and reducing its load while maintaining ease of antenna control.
3Use of energy by moving object
If antennas are powered on demand, then power consumption is reduced, but coordination complexity increases
Solution Approach 1:
The patent combines the receiver controller functions with antenna power management in a single integrated component. By merging the RF signal reception control and antenna power switching functions into one controller, the system reduces coordination complexity despite the added power management tasks. This integration allows seamless coordination of antenna powering with polling operations without requiring separate control mechanisms.
