Wireless Direct Transfer Trip Edge Routing for Low-Latency Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless networks lack the broadcasting capabilities and suffer from high transmission latency, making them ineffective for implementing Direct Transfer Trip (DTT) methodologies that require rapid response to electrical faults.
Innovation Solution
A wireless network-based DTT system utilizing low-latency communications and edge computing devices to facilitate multi-device notifications, enabling rapid tripping of remote circuit breakers by determining alert groups based on device attributes and locations, and using edge computing devices to forward alerts with minimal latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wireless networks are used for DTT, then device connectivity and flexibility are improved, but transmission latency increases and reliability deteriorates
Solution Approach 1:
The system segments the alert distribution function by introducing edge computing devices that operate independently from the core network. These edge devices receive alerts from the DTT hub and independently distribute them to target devices, creating a hierarchical structure that reduces core network latency while maintaining wireless connectivity flexibility.
Solution Approach 2:
Edge computing devices serve as intermediaries between the DTT hub and target devices. They buffer and forward alerts, enabling the system to achieve wired-network-comparable latency over wireless connections by preprocessing and routing alerts closer to the destination before they reach the target devices.
2Adaptability or versatility
If traditional wireless networks are used for DTT, then deployment flexibility is improved, but transmission reliability deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-establishing alert groups and assigning target devices to specific edge computing devices before faults occur. This pre-configuration ensures that when a fault happens, the alert distribution path is already validated and ready, improving reliability while maintaining the flexibility of wireless deployment.
Solution Approach 2:
The system implements feedback mechanisms where edge computing devices confirm successful alert delivery to the DTT hub. This acknowledgment protocol ensures reliable transmission by verifying that alerts reached their destination, compensating for the inherently less reliable wireless medium while preserving deployment flexibility.
3Adaptability or versatility
If alert groups are dynamically managed based on device attributes, then system adaptability is improved, but device complexity increases
Solution Approach 1:
Target devices automatically provide their attributes (location, device type, operational parameters) to the DTT hub without requiring manual configuration. The hub autonomously creates and manages alert groups based on received attributes, enabling dynamic adaptability while keeping individual devices simple and avoiding complex manual setup procedures.
