Multi-bandwidth Communication for Fluid Distribution Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid distribution networks face challenges in efficiently transmitting high volumes of data from electronic pumps due to bandwidth limitations, especially in remote locations, where long-range wireless connections are often bandwidth-limited, making it difficult to transfer large amounts of data in real-time.
Innovation Solution
Implementing a multi-bandwidth approach that uses both sub-gigahertz and higher frequency wireless signals to transmit data, allowing for short-range high-bandwidth data transfer when mobile data collection devices are within range, and storing measurements for later transfer, enabling efficient data collection and predictive maintenance.

1Length of stationary object
If long-range wireless connections are used to transmit data from electronic pumps in remote locations, then data can be transmitted over large geographic regions, but bandwidth is limited and large volumes of data cannot be transferred in real-time
Solution Approach 1:
The patent segments data transmission into two distinct pathways: high-volume data is stored locally and transmitted via high-bandwidth short-range connections when mobile devices are nearby, while low-volume critical data is transmitted continuously via low-bandwidth long-range connections. This segmentation resolves the contradiction by matching data transmission methods to data priority and volume requirements.
Solution Approach 2:
The system dynamically selects transmission pathways based on real-time conditions. When a mobile data collection device is within range of an electronic pump, the system switches to high-bandwidth short-range transmission for high-volume data. When no mobile device is present, the system uses low-bandwidth long-range transmission for essential data. This dynamic adaptation resolves the contradiction between coverage range and data transfer rate.
2Reliability
If high-volume data is transmitted continuously via long-range wireless connections, then real-time monitoring is achieved, but bandwidth consumption increases and operational efficiency decreases
Solution Approach 1:
The system applies partial action by transmitting only the necessary subset of data via the long-range low-bandwidth connection (critical operational data), while high-volume data is transmitted in batches when high-bandwidth connections are available. This partial transmission approach maintains real-time monitoring capability for critical parameters while significantly reducing bandwidth consumption and improving operational efficiency.
3Loss of information
If all measurements are stored and transmitted via high-bandwidth connections, then complete data sets are available for analysis, but bandwidth consumption increases and is unsustainable in remote locations
Solution Approach 1:
The patent applies local quality by differentiating data transmission strategies based on data characteristics and destination. High-volume measurement data is transmitted via high-bandwidth short-range connections when available, while critical operational data is transmitted via low-bandwidth long-range connections. This localized optimization of transmission quality based on data priority and available resources resolves the contradiction between data completeness and bandwidth consumption.
