Agricultural Control System for Overlap Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In agricultural operations, overlapping coverage areas during collaborative machine tasks lead to inefficient and wasteful application of agricultural products, and miscommunication can result in missed sections of crops, causing harm to the crop due to improper processing.
Innovation Solution
A system where machines share coverage data through a common server to guide each other in their operations, preventing duplicate work by determining areas already processed by other machines, thereby optimizing product application and reducing bandwidth requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple machines operate collaboratively in a field without coordination, then operational speed increases, but duplicate processing and product waste occur
Solution Approach 1:
Machines transmit coverage data to a server and receive feedback about areas already processed by other machines. The system uses this feedback information to adjust machine paths and operations in real-time, preventing duplicate processing and product waste while maintaining high operational speed
Solution Approach 2:
A central server acts as an intermediary between multiple collaborative machines. The server collects coverage data from all machines, processes this information, and distributes guidance data back to the machines, enabling coordinated operation without direct machine-to-machine communication
2Device complexity
If machines operate independently without sharing coverage data, then system complexity is reduced, but field coverage accuracy deteriorates
Solution Approach 1:
The central server serves as an intermediary that handles the complex tasks of data collection, processing, and path optimization. Individual machines maintain relatively simple onboard systems while relying on the server for coverage data and guidance information, achieving high coverage accuracy without excessive complexity at the machine level
Solution Approach 2:
The system uses digital copies of coverage data (maps and spatial information) to represent field processing status. These digital representations allow the system to plan and coordinate machine paths accurately without requiring complex physical sensing or communication infrastructure
3Reliability
If comprehensive coverage data is shared between machines, then duplicate processing is prevented, but bandwidth requirements increase
Solution Approach 1:
The system extracts and transmits only the essential elements needed for coordination - coverage data representing processed areas and guidance data representing recommended paths. By taking out only the critical information rather than sharing all possible data, the system prevents duplicate processing while minimizing bandwidth consumption

AI summary
A machine to perform operations in a field includes a memory including instructions and processing circuitry that is configured by the instructions to receive coverage data from a server, where the coverage data is indicative of operations executed by another machine in the field. The processing circuitry that is further configured by the instructions to determine, using the coverage data, a strategy for performing operations in the field, where the strategy reduces the likelihood of the machine from processing an area of the field that was previously processed by the other machine. The processing circuitry that is further configured by the instructions to actuate the machine according to the strategy.
