Wireless Grain Sensor Nodes for Bulk Storage Condition Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grain storage monitoring systems face challenges due to harsh environmental conditions, leading to short lifespans and high maintenance costs, and are limited to tracking within a single grain bin, restricting their effectiveness in managing particulate bulk goods.
Innovation Solution
A system of wireless sensor nodes that can be freely distributed within bulk goods, coordinating with an analysis engine and task manager to collect and analyze data on storage conditions, integrated with a management platform for real-time monitoring and control, allowing for tracking during storage, transportation, and processing, and enabling quality control and supply chain management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent sensor probes are installed in grain bins, then monitoring capability is achieved, but device complexity and maintenance cost increase
Solution Approach 1:
The system divides the monitoring function into multiple independent wireless sensor nodes distributed throughout the grain bulk. Each node operates autonomously and communicates wirelessly, eliminating the need for complex permanent installations. This segmentation transforms a single complex permanent system into multiple simple, independent units that can be freely positioned and replaced.
Solution Approach 2:
The patent employs inexpensive wireless sensor nodes that can be disposed of or replaced easily when their battery life expires or they malfunction. These nodes are designed to be temporary rather than permanent, contrasting with traditional expensive permanent probes. The low cost allows operators to replace nodes without significant investment, solving the maintenance cost problem.
2Reliability
If permanent sensor probes are used, then monitoring is possible, but lifespan decreases due to harsh environmental conditions
Solution Approach 1:
The wireless sensor nodes are designed as temporary, disposable units with sealed enclosures that protect against harsh grain storage environments. When a node's battery expires or it fails, it is simply replaced rather than repaired, extending the effective monitoring availability without requiring long-lived components. The low cost enables continuous monitoring through replacement rather than maintenance of permanent fixtures.
Solution Approach 2:
The sensor nodes utilize sealed enclosure designs that protect internal electronics from moisture, temperature extremes, and grain contact. This protective sealing allows the nodes to survive harsh environmental conditions throughout their operational life, maintaining reliability despite the inherently limited lifespan of battery-powered temporary devices.
3Measurement precision
If sensor probes are permanently fixed in grain bins, then local monitoring is achieved, but tracking during transportation and processing is restricted
Solution Approach 1:
The wireless sensor nodes are designed to be universal and adaptable to multiple stages of grain handling including storage, transportation, and processing. Unlike permanent probes fixed to specific bins, these nodes can be attached to grain bags, containers, or equipment and moved freely between locations. This universality enables continuous tracking throughout the entire supply chain while maintaining precise local condition monitoring capabilities.
Solution Approach 2:
The system transitions from static permanent installations to dynamic, mobile wireless nodes that can be repositioned as grain moves through different storage and processing facilities. The nodes adapt to changing environments and locations, providing continuous monitoring capability whether grain is stationary in a bin or moving through transportation and processing operations.
