Machine Health Data Transmission Control for Weak Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with weak or unreliable wireless connections, such as mines, machine health data downloads from machinery to off-board systems are often interrupted, leading to lost or corrupted data, which increases network traffic and reduces bandwidth, as existing systems fail to ensure uninterrupted data transmission and account for weak network conditions.
Innovation Solution
A method and system that collect machine health data, determine communication and data characteristics, and decide whether to transmit data based on these characteristics, using a module to assess network conditions and optimize data transmission to prevent interruptions, thereby reducing re-initiated transmissions and network burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If machine health data is transmitted continuously over wireless networks, then data completeness is improved, but network reliability deteriorates in weak signal environments
Solution Approach 1:
The system performs preliminary assessment of network conditions and data characteristics before transmission begins. It pre-determines whether to transmit data based on predicted transmission reliability, avoiding initiation of transmissions that are likely to fail in weak signal environments.
Solution Approach 2:
The system continuously monitors network conditions and uses this feedback to dynamically adjust transmission decisions. By assessing current network state and comparing it against thresholds, the system learns from network behavior patterns to make more accurate transmission predictions and adjustments.
2Loss of information
If data transmission is attempted in weak network conditions, then data collection completeness is improved, but network bandwidth availability deteriorates due to re-initiated transmissions
Solution Approach 1:
The system performs preliminary assessment of network conditions and data characteristics before transmission begins. It pre-determines whether to transmit data based on predicted transmission reliability, avoiding initiation of transmissions that are likely to fail in weak signal environments.
Solution Approach 2:
The system changes the parameter of transmission decision by introducing a predictive assessment step that evaluates network conditions and data characteristics. This parameter change allows the system to adapt transmission behavior based on predicted reliability, avoiding bandwidth-consuming re-transmissions.
