Field Machine Work Assistance Using Engine Load Event Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work assistance systems for machines traveling in fields do not adequately address events like machine sinking, which can hinder work, by failing to consider measures such as increasing engine RPM.
Innovation Solution
A work assistance system that includes an estimation unit to predict the occurrence of events like machine sinking based on engine load changes, and an output unit to provide data for taking preventive measures, such as increasing engine RPM.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing work assistance systems only provide basic operational advice, then system complexity is reduced, but the ability to prevent work-hindering events like machine sinking is insufficient
Solution Approach 1:
The estimation unit performs preliminary assessment of sinking risk based on current engine load and historical data before the machine actually sinks. This allows preventive measures to be taken in advance, improving reliability without requiring complex real-time intervention systems.
Solution Approach 2:
The system continuously monitors engine load and compares it with historical data to provide feedback on sinking risk. This feedback mechanism enables the system to adaptively adjust operational advice, enhancing reliability through data-driven decision making while maintaining manageable system complexity.
2Loss of information
If the system provides detailed real-time monitoring and estimation functions, then work assistance effectiveness is improved, but information processing requirements increase
Solution Approach 1:
The system extracts only the most critical parameters (engine load, position, historical sinking data) from the available data stream, processing only what is necessary for accurate sinking risk estimation. This reduces information processing requirements while maintaining complete information for effective work assistance.
Solution Approach 2:
The estimated sinking risk information serves multiple purposes: it guides operational adjustments, informs maintenance scheduling, and provides predictive analytics. This multi-functionality maximizes the value of processed information, reducing the need for separate data processing systems.
Data Source
AI summary
A work assistance system is a system used together with a work machine, wherein an estimation unit and an output unit are provided. The work machine has an engine as the power source thereof, and travels in a field. On the basis of at least the magnitude of the load of the engine, the estimation unit estimates whether there is an occurrence of a target event that accompanies fluctuations in the load. The output unit outputs output data corresponding to the estimation results from the estimation unit.
