Mining Machine Management System Using GPS Landmark Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The productivity of mining operations is reduced when mining machines come into contact with installed structures, leading to operational stoppages and decreased efficiency.
Innovation Solution
A management system for mining machines that uses landmarks and non-contact sensors to detect relative positions, registers these positions using GPS, and sets prohibited areas to prevent contact, while generating travel routes that avoid these areas, ensuring the mining machines operate safely and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a structure such as a landmark is installed at a mine, then the mining machine can detect position and operate safely, but the mining machine may come into contact with the structure and productivity is reduced
Solution Approach 1:
The system pre-registers the positions of landmarks using GPS before mining operations begin. The central control apparatus stores landmark position information and uses it to generate travel routes that proactively avoid these locations, preventing contact before it can occur
Solution Approach 2:
The patent introduces a non-contact sensor as an intermediary between the mining machine and landmarks. The sensor detects landmarks remotely without requiring physical contact, allowing the machine to identify and avoid landmark positions while maintaining operational efficiency
2Productivity
If the mining machine operates without position monitoring, then productivity is maintained, but contact with structures may occur causing operational stoppages
Solution Approach 1:
The system continuously monitors the mining machine's position using non-contact sensors that detect landmarks in real-time. This feedback loop allows the control apparatus to adjust travel routes dynamically, ensuring the machine avoids landmarks while maintaining continuous operation and high productivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively suppresses reductions in productivity by preventing contact between mining machines and landmarks, allowing for continuous and safe operation, thereby enhancing operational efficiency and safety.
Implementation Method 1
a storage device that registers a position of the landmark detected using the Global Positioning System
Implementation Method 2
a landmark that is placed at a mine and allows a non-contact sensor placed on the mining machine able to run at the mine to detect a relative position of the landmark and the mining machine

AI summary
A management system of a mining machine includes: a landmark that is placed at a mine and allows a non-contact sensor placed on the mining machine able to run at the mine to detect a relative position of the landmark and the mining machine; a storage device that registers a position of the landmark detected using the Global Positioning System; and a processing device that sets, upon the registration, a prohibited area where an entry of the mining machine is prohibited such that the position of the landmark is included in the prohibited area.
