Peer-to-Peer Machine Communication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication between machines at a work site is often unreliable and delayed due to the need for remote nodes, which can increase operational time and efficiency issues in tasks like material handling and coordination.
Innovation Solution
A short-range peer-to-peer communication system that allows machines to transmit and receive signals directly, using protocols like Bluetooth LE, eliminating the need for remote network nodes and improving signal latency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If remote nodes are used for machine communication, then communication coverage is extended, but communication reliability decreases and latency increases
Solution Approach 1:
The communication system is segmented into direct peer-to-peer communication channels between machines, eliminating the need for remote nodes. Each machine communicates directly with others in its immediate vicinity, creating multiple independent communication paths that improve reliability without requiring extended infrastructure.
2Length of stationary object
If remote nodes are used for machine communication, then communication coverage is extended, but signal latency increases
Solution Approach 1:
The remote nodes are extracted from the communication path, allowing machines to communicate directly with each other. This eliminates the intermediate transmission steps through remote nodes, significantly reducing signal latency while maintaining communication effectiveness within direct range.
3Reliability
If direct peer-to-peer communication is implemented, then communication reliability improves, but communication range is limited
Solution Approach 1:
The communication system dynamically adapts to machine positions and movements on the worksite. As machines move, their communication ranges adjust accordingly, allowing the system to maintain reliable direct connections by continuously optimizing which machines communicate peer-to-peer based on their current spatial relationships.
