Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mining machine operation simulation systems struggle to accurately distinguish and specify the route traveled by mining machines, which is crucial for improving productivity and efficiency in mining operations.
Innovation Solution
A mining machine management system that includes a position information detection unit, a determination unit, and a storage unit to analyze and determine if a second route matches a first route by comparing position information, route nodes, and link connections, with criteria such as node correspondence, slope differences, and travel distance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operation simulation systems are used to track mining machines, then productivity analysis can be performed, but the accuracy in distinguishing and specifying the route travelled is insufficient
Solution Approach 1:
The route is segmented into multiple nodes at predetermined distances along the path. By dividing the continuous route into discrete segments with specific nodes, the system can accurately track and identify the mining machine's position at each segment point, thereby improving route identification accuracy and specification reliability
Solution Approach 2:
The patent creates a virtual copy of the actual route by mapping real-world positions to predetermined nodes in a digital model. This copying mechanism allows the system to accurately represent and analyze the mining machine's travel path by comparing actual position data against the predefined node structure
2Loss of information
If multiple position information points are collected to define a route, then route analysis becomes possible, but the complexity of determining route identity increases
Solution Approach 1:
The system performs preliminary action by pre-defining nodes and route structures before the mining machine actually travels. This advance preparation of the route model with predetermined nodes simplifies the determination process, as the system only needs to check if collected position information matches the pre-established node criteria rather than creating and analyzing routes in real-time
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously compares collected position information against the predefined node criteria. This feedback loop allows the system to verify route identity by checking whether position information groups correspond to the expected node patterns, thereby managing complexity through systematic verification

AI summary
A mining machine management system includes: a position information detection unit detecting position information related to a position of a mining machine; and a determination unit determining whether a second route corresponding to a position information group obtained from a plurality of pieces of the position information detected when the mining machine is in operation is identical to a first route that is a route taken by the mining machine departing a predetermined first position, passing a second position at which a load is loaded, and moving to a third position at which the load is removed, based on at least route information of the first route and the position information group, the route information including a plurality of nodes present at every predetermined distance of the first route and a link connecting the nodes adjacent to each other.
