Engineering Contradiction Analysis
1Measurement precision
If operation simulation systems are used to track mining machines, then productivity analysis and driver instruction can be performed, but the accuracy in distinguishing and specifying the route traveled by the mining machine is insufficient
Solution Approach 1:
The route is segmented into multiple nodes representing key positions (departure position, loading position, discharging position, and intermediate positions). By dividing the continuous route into discrete segments connected by nodes, the system can accurately track and specify the mining machine's path through the mine, resolving the issue of insufficient route distinction accuracy.
Solution Approach 2:
The system uses feedback from position information detection units to continuously update and correct the mining machine's location relative to the predefined nodes. This feedback mechanism enables real-time route specification and allows the system to distinguish whether the machine is traveling on the outbound route (to loading position) or inbound route (from discharging position), thereby improving both measurement precision and reliability.
2Loss of information
If position information is collected continuously to track the mining machine, then route analysis can be performed, but position errors accumulate without correction
Solution Approach 1:
The system pre-defines nodes at every predetermined distance along the expected route before the mining machine begins operation. These nodes serve as reference points that are established in advance, allowing the system to compare actual position information against known correct locations and correct accumulated position errors.
Solution Approach 2:
The determination unit continuously compares detected position information with the predefined node positions and corrects node positions when discrepancies are detected. This feedback loop prevents position information accuracy degradation by regularly recalibrating the node positions based on actual measurements, thereby maintaining measurement precision over time.

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 a second route corresponding to a plurality of pieces of the position information is identical to a first route based on at least whether a position of each node corresponds with the position information, the node being a piece of information related to a position of the 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.
