Dump Truck Map Data Update Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operation management systems for dump trucks require all vehicles to be stopped for map data updates, which can degrade operational efficiency in mining sites with multiple fields, as updating map data in a centralized control center necessitates halting all dump trucks.
Innovation Solution
Implementing an operation management system that allows partial map data updates without stopping all dump trucks by defining closed regions on the map and checking if any dump trucks are present within these regions before updating, enabling continuous operation of dump trucks not in the affected areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If map data are updated in a centralized control center, then map data consistency is improved, but all dump trucks must be stopped causing productivity to deteriorate
Solution Approach 1:
The patent divides the mine site into multiple closed regions and enables independent map data updates for each region. When map data needs updating, only dump trucks within the specific closed region being updated are affected, while trucks in other regions continue operating normally. This segmentation eliminates the need to stop all trucks for any map update, resolving the contradiction between data consistency and operational productivity.
2Adaptability or versatility
If map data are updated frequently to reflect road changes, then adaptability to mining site changes is improved, but operational efficiency deteriorates due to repeated stoppages
Solution Approach 1:
By segmenting the mine site into closed regions with independent map data management, the system allows frequent updates of map data for specific regions without affecting operations in other regions. This enables the mining site to adapt quickly to road changes while maintaining continuous productivity across the entire operation.
Solution Approach 2:
The system dynamically determines whether to update map data based on the real-time locations of dump trucks. Map data updates are performed only when no trucks are present in the affected closed region, allowing the system to adapt to changing operational conditions and minimize disruptions to productivity.
3Measurement precision
If all dump trucks are stopped for map data updates, then measurement precision of map data is improved, but loss of time increases
Solution Approach 1:
The patent implements region-based map data management where updates are confined to specific closed regions. This segmentation allows map data accuracy to be improved for individual regions without requiring stoppage of the entire fleet, thereby reducing operational downtime while maintaining data precision where needed.
