Automatic Return Route Generation for Mining Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Teaching routes to mobile mining machines is time-consuming, as each route must be driven from start to finish, which is inefficient, especially for routes that are essentially the reverse of each other.
Innovation Solution
A method to determine a return route for mobile mining machines by reversing the route points and deleting additional control data of the drive route, allowing for automatic control using a data processing device to generate and store the return route data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If each route is taught by driving the mining vehicle from start to finish, then the route data is accurate and complete, but the time required for teaching is excessive
Solution Approach 1:
The patent applies inversion by teaching only one direction of a route (e.g., forward direction from loading to unloading site) and then automatically generating the return route by reversing the route points and adjusting control data. This eliminates the need to manually teach both directions, reducing teaching time while maintaining route accuracy through systematic data transformation.
Solution Approach 2:
The patent performs preliminary action by storing complete route data for one direction, then using this pre-stored data to automatically generate the return route through computational reversal. This preliminary storage and processing eliminates the need for redundant teaching operations, significantly reducing the time required while ensuring data accuracy through systematic transformation.
2Reliability
If complete route data including control data is stored for manual teaching, then the vehicle can follow the route accurately, but the data processing complexity increases
Solution Approach 1:
The patent uses copying by creating a return route from the forward route data through systematic reversal of route points and adjustment of control data. Instead of manually teaching the return route (which would increase complexity), the system copies and transforms the existing forward route data, maintaining reliability while reducing data processing complexity through automated generation.
3Manufacturing precision
If routes are taught manually for automatic control, then the control precision is high, but the productivity decreases
Solution Approach 1:
The patent applies inversion to improve productivity by teaching only one direction of the route and automatically generating the return route through reversal. This reduces route setup time significantly while maintaining control precision through systematic transformation of route points and control data, thereby increasing overall productivity without sacrificing accuracy.
Solution Approach 2:
The patent performs preliminary action by storing complete forward route data and using it to automatically generate return route data through computational reversal. This preliminary processing improves productivity by eliminating redundant teaching operations while maintaining control precision through automated data transformation that preserves the essential route characteristics.

AI summary
The present invention relates to a method of determining routes for arranging automatic control of a mobile mining machine. A return route is determined computer-aidedly for the mining machine on the basis of data concerning a route taught by driving by executing, by a data processing device configured for generating return routes, at least the following steps: determining a route identifier for the return route, determining as route points of the return route at least some of the route points of the drive route in a reverse order, wherein when determining route point data of the return route on the basis of the route point data of the drive route, deleting additional control data associated with one or more route points of the drive route, and storing the data determining the return route to be used for automatically controlling the mining machine.
