Haul Route Terrain Mapping for Adaptive Machine Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing worksite management systems fail to efficiently adapt machine operations to varying conditions of haul routes, leading to operator discomfort and increased maintenance costs due to the inability to dynamically adjust powertrain parameters based on real-time terrain data.
Innovation Solution
A worksite management system equipped with sensor modules and on-board controllers that generate alerts for operators to adjust operating parameters, such as powertrain output, by referencing a pre-generated or learned terrain map of haul routes, allowing for real-time adaptation to conditions like rough areas and potholes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machines operate on deteriorated haul routes without real-time condition data, then maintenance costs and operator discomfort increase, but the system complexity and cost of implementing real-time monitoring and control systems also increase
Solution Approach 1:
The system implements feedback by having machines transmit their location data to the central facility, which then provides route condition information back to the machines. This closed-loop feedback enables machines to adapt their operation to actual route conditions, improving reliability without requiring overly complex decentralized systems.
Solution Approach 2:
A central facility acts as an intermediary between the machines and the route condition data. Instead of each machine having complex direct access to all route sensors and data, the central facility consolidates and processes this information, simplifying the overall system architecture while maintaining comprehensive monitoring capabilities.
2Adaptability or versatility
If machines are conservatively configured for theoretical conditions, then they can operate under various conditions, but they cannot be easily reconfigured to match actual worksite conditions
Solution Approach 1:
The system enables dynamic adaptation by allowing machines to receive real-time route condition data and adjust their operational parameters accordingly. Instead of requiring physical reconfiguration, the machines dynamically adapt through software-based control adjustments transmitted from the central facility.
Solution Approach 2:
The system changes operational parameters (such as speed, power output, and route selection) based on received route condition data. This allows machines to adapt to varying worksite conditions by modifying their operational parameters rather than requiring physical reconfiguration, maintaining ease of manufacture while improving adaptability.
3Object-affected harmful factors
If small rough areas on haul routes are not monitored, then the system remains simple, but most maintenance costs and operator discomfort are caused by these localized conditions
Solution Approach 1:
The system segments the haul route into multiple monitoring zones and tracks machine location within these segments. By dividing the route into manageable sections, the system can efficiently monitor specific rough areas without requiring continuous analysis of the entire route, making localized condition detection feasible while maintaining system simplicity.
Solution Approach 2:
The system replaces physical inspection methods with electronic sensing and data transmission. Sensors and communication systems substitute for manual route inspections, enabling automated detection of localized rough areas without significant increases in system complexity.

AI summary
A worksite management system for a worksite includes a sensor module associated with each of one or more machines working on the worksite. The sensor module generates a signal indicative of a location of a corresponding one of a machine from the one or more machines. An on-board controller associated with each of the one or more machines receives the signal corresponding to the location of the corresponding one of the machine on the worksite, and looks up the location of the corresponding one of the machine in at least one of a pre-generated or learned terrain map of a network of haul routes. The on-board controller identifies at least one condition of the haul route at the looked-up location, and then generates an alert for an operator to perform one or more recommended actions with respect to an operating parameter of the corresponding one of the machine.
