Electronic Equipment Controller for Satellite Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic equipment experiences increased power consumption when constantly receiving satellite signals for disaster-related information, which is necessary for continuous operation but inefficient in terms of energy usage.
Innovation Solution
The electronic equipment includes a controller that determines whether to process satellite signals based on its current position, stopping processing when cellular communication is available and starting it when cellular communication is not available, thereby reducing power consumption by only receiving and processing satellite signals when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic equipment constantly receives satellite signals for disaster-related information, then the reliability of information acquisition is improved, but the power consumption increases
Solution Approach 1:
The controller periodically checks cellular communication availability and alternates between satellite signal reception mode and cellular communication mode. This periodic switching ensures disaster information is acquired reliably when needed while minimizing power consumption by using the lower-power cellular mode when available.
Solution Approach 2:
The controller acts as an intermediary that manages two communication pathways (satellite and cellular). It selectively routes disaster information acquisition through the appropriate channel based on cellular availability, combining the reliability of satellite communication with the energy efficiency of cellular communication.
2Loss of information
If the electronic equipment processes satellite signals continuously, then the information reception completeness is improved, but the energy efficiency deteriorates
Solution Approach 1:
The system implements periodic monitoring of cellular communication status and switches between satellite and cellular modes accordingly. This ensures complete information reception through satellite when cellular is unavailable, while achieving energy efficiency by using cellular mode when available.
Solution Approach 2:
The controller dynamically changes the operational parameters of the receiver based on cellular communication availability. When cellular is available, it reduces satellite signal processing activity; when cellular is unavailable, it increases satellite signal processing to ensure complete information reception.
3Adaptability or versatility
If the electronic equipment uses satellite communication outside cellular coverage, then the adaptability to different environments is improved, but the power consumption increases
Solution Approach 1:
The controller periodically assesses cellular communication availability and adapts the communication mode accordingly. This enables the system to adapt to different environments (cellular coverage and non-coverage areas) while minimizing power consumption by using cellular mode when available.
Solution Approach 2:
The system dynamically adjusts its communication strategy based on environmental conditions (cellular coverage availability). It transitions between satellite-only mode in remote areas and cellular-preferred mode in covered areas, optimizing both adaptability and power consumption.
