Dynamic Sensor Priority Arbitration for Multi-Bus Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information processing systems with multiple sensors connected, existing technologies face challenges in dynamically adjusting priority based on changing situations, leading to difficulties in effectively transferring sensor information in real-time, especially when some sensors fail or are affected by weather conditions.
Innovation Solution
The system employs a priority arbitration mechanism using multiple buses to dynamically determine and adjust communication priorities based on sensor conditions, allowing for flexible prioritization of sensor information processing and ensuring robustness by switching access to the most suitable bus according to the current sensor state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed priority order is used for bus arbitration, then device compatibility and system stability are improved, but real-time responsiveness to changing sensor conditions deteriorates
Solution Approach 1:
The patent implements dynamic priority assignment where the arbitration priority of each sensor is not fixed but changes based on real-time detection results. The priority determination unit dynamically adjusts priorities according to the current operational context, allowing the system to respond to changing conditions while maintaining stable bus arbitration through structured priority management.
2Adaptability or versatility
If multiple sensors are connected to share bus resources, then system versatility and sensor integration are improved, but information transfer reliability under varying conditions deteriorates
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different sensors based on their specific operational requirements and current state. Each sensor receives a priority level tailored to its current importance, allowing critical sensors to maintain reliable communication while less critical sensors use shared bus resources efficiently.
3Ease of operation
If priority is predetermined based on device information, then arbitration simplicity and system ease of operation are improved, but adaptability to changing sensor states and conditions deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the priority determination unit continuously monitors sensor detection results and operational conditions, then adjusts arbitration priorities accordingly. This feedback loop maintains arbitration simplicity through automated priority management while adapting to changing sensor states without requiring complex manual reconfiguration.
