Agricultural Field-Working Device Data Filtering for Low-Bandwidth Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural devices face high data transmission costs and limited bandwidth due to sparse cellular coverage, leading to inefficient data analysis and potential overflow when using mobile broadband connections, and predefined data selection methods fail to capture relevant measurements effectively.
Innovation Solution
An agricultural device equipped with a data processing unit that filters data based on predefined criteria, storing measurements temporarily and sending only those meeting duration, difference, and key value thresholds, reducing redundant data transmission.

Engineering Contradiction Analysis
1Loss of information
If all aggregated data is sent using mobile broadband connection, then complete data analysis is enabled, but transmission costs increase and bandwidth limitations cause data overflow
Solution Approach 1:
The patent extracts only the essential and changed measurements from the complete aggregated data set before transmission. The data processing unit identifies and transmits only measurements that meet specific criteria (changes exceeding thresholds, duration-based selections, key value range matches), leaving redundant data at the source device. This extraction approach maintains data completeness for analysis while dramatically reducing transmission volume and associated costs.
2Measurement precision
If data transmission frequency is increased to capture all changes, then measurement resolution is improved, but bandwidth requirements exceed available capacity
Solution Approach 1:
The patent changes the transmission parameter from continuous/high-frequency to event-driven/variable-frequency based on measurement significance. Instead of transmitting all measurements at a fixed high rate, the system dynamically adjusts transmission timing based on whether measurements meet predefined criteria (threshold exceedances, duration conditions, key value ranges). This parameter change maintains measurement precision for significant events while reducing overall transmission volume to match available bandwidth.
3Quantity of substance
If data filtering criteria are made more selective to reduce transmission, then bandwidth usage decreases, but relevant measurements may be missed
Solution Approach 1:
The patent segments the data filtering process into multiple independent criterion checks that work together to ensure comprehensive yet selective transmission. Different measurement types are evaluated against different criteria (threshold-based for significant changes, duration-based for sustained conditions, key value range for critical parameters). This segmentation allows the system to reduce transmission volume through selective filtering while maintaining relevance by ensuring each measurement type is evaluated against appropriate criteria that capture its significance.
