Locomotive Access Point Synchronization for Data Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a locomotive consist, network components within multiple locomotives experience interference and low data transfer rates due to unsynchronized communications, which existing systems fail to adequately address.
Innovation Solution
A method and system where a selected access point outputs a synchronization signal to synchronize data communication among access points within the locomotive consist, using techniques like frequency division multiple access (FDMA) and multiple-input multiple-output (MIMO) to manage bandwidth and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple access points transmit data simultaneously without synchronization, then communication capacity is increased, but interference increases and data transfer rates decrease
Solution Approach 1:
The patent implements periodic time slots for data transmission, where each access point transmits data in designated time intervals rather than continuously. This periodic structure allows the system to maintain high communication capacity while reducing interference through controlled transmission timing.
Solution Approach 2:
The system performs preliminary synchronization before data transmission begins. Access points exchange synchronization signals and establish timing relationships in advance, ensuring that subsequent data transmissions occur without interference while maintaining high throughput.
2Productivity
If multiple access points transmit data simultaneously, then network capacity is improved, but network congestion increases
Solution Approach 1:
The patent segments the communication medium into distinct time slots and frequency channels. This segmentation allows multiple access points to transmit data simultaneously in different time intervals or frequency bands, increasing overall network capacity while preventing congestion through organized resource allocation.
Solution Approach 2:
The system uses periodic time-division multiplexing where data transmissions occur in structured intervals. This periodic organization enables the network to handle multiple data streams efficiently, increasing capacity while maintaining low congestion through predictable transmission patterns.
3Reliability
If synchronization signals are implemented among access points, then data transfer reliability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a centralized controller or master access point that generates and distributes synchronization signals to all other access points. This intermediary approach ensures reliable synchronization across the network while keeping individual access point complexity low, as each device only needs to receive and follow synchronization commands rather than independently manage synchronization.
Data Source
AI summary
A method for controlling data communication among two or more of access points within a locomotive consist is disclosed. The method may include selecting, from among the two or more access points, a first access point to output a synchronization signal. The method may also include outputting the synchronization signal from the first access point to the remaining one or more access points, wherein the synchronization signal may be used to synchronize data communication among the two or more access points.
