Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling material transport and blending at mine sites are inefficient, as they lack real-time data monitoring and optimization, leading to suboptimal material blends and increased costs, particularly in coal transportation where improper blending can result in inefficient power plant operations and higher fuel consumption.
Innovation Solution
A site management system that includes an environment monitoring system with a controller to track material movement, monitor cumulative material blends, and modify operating instructions for machines in real-time to maintain optimal blends at processors, utilizing real-time and anticipated environmental information to adjust machine operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time monitoring and control systems are implemented to optimize material blends, then manufacturing precision and productivity are improved, but device complexity increases
Solution Approach 1:
The system implements real-time feedback loops where material blend data is continuously monitored at processors, compared against target specifications, and used to dynamically adjust machine dispatch decisions. This closed-loop control ensures manufacturing precision is maintained through continuous correction rather than complex pre-planning.
Solution Approach 2:
The system enables self-service by allowing the monitoring system to automatically adjust dispatch instructions based on real-time blend data without requiring complex external intervention. The system serves itself by using its own collected data to make optimization decisions, reducing the need for additional complex control mechanisms.
2Loss of information
If comprehensive real-time data collection from all machines is implemented, then information completeness is improved, but loss of time for data processing increases
Solution Approach 1:
The system extracts only the essential real-time data elements needed for blend optimization (material type, quantity, location, and processor destination) from the full machine operational dataset. This selective extraction maintains information completeness for blend control while minimizing data processing time by excluding unnecessary information.
3Adaptability or versatility
If dynamic adjustment of machine dispatch based on real-time conditions is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system implements dynamics by continuously adapting machine dispatch instructions based on real-time material blend data and changing processor needs. Dispatch priorities, destinations, and assignments are dynamically adjusted rather than following static schedules, allowing the system to adapt to varying conditions without requiring overly complex control architecture.
4Productivity
If multi-stage dispatching systems with environmental adaptation are implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating optimal dispatch assignments based on current environmental conditions and material blend requirements before machines actually arrive at processors. This advance preparation enables efficient multi-stage dispatching without requiring complex real-time decision-making during machine operations, thus improving productivity while managing system complexity.
Data Source
AI summary
A site management system for tracking material movement in an environment includes a plurality of material sources, one or more processors, and a plurality of machines. Each of the machines operates according to operating instructions to capture material from one material source and deliver the material at or near at least one processor. The site management system also includes an environment monitoring system having a controller configured to monitor movement of the machines, track a cumulative material blend at each of the processors based on the movement of the machines, and modify the operating instructions to maintain the cumulative material blend within a target blend range.
