Autonomous Machine Controller with Heartbeat Signal Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for operating machines in mining and excavating operations are inefficient in allowing machines to operate in remote or autonomous modes while performing multiple operations with minimal supervision, as they are not capable of handling diverse tasks effectively.
Innovation Solution
A system and method that enables machines to operate in manual, remote, or autonomous modes, utilizing a controller, wireless communication devices, GPS antennas, and computer mapping systems to manage operations, with a heartbeat signal for monitoring and control, allowing machines to perform multiple tasks independently or under remote supervision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a machine operates in autonomous mode using basic position data transmission, then the number of operators can be reduced, but the machine cannot perform multiple different operations with little supervision
Solution Approach 1:
The system enables a single machine to perform multiple different operations (harvesting, transporting, spreading, etc.) through autonomous mode by integrating various implements and using a unified control architecture that can adapt to different task requirements without manual intervention
Solution Approach 2:
A remote operator serves as an intermediary between automated systems and multiple machines, providing supervisory control that allows machines to operate autonomously while still coordinating complex multi-machine operations through a human mediator who handles high-level decision-making
2Productivity
If multiple machines are operated remotely or autonomously, then operational efficiency increases, but the system complexity increases
Solution Approach 1:
Multiple machines are merged into a single coordinated fleet managed by one remote operator, combining their operations under unified supervision to improve overall productivity while managing complexity through centralized control rather than requiring separate operators for each machine
Solution Approach 2:
The control system is segmented into autonomous machine-level controllers that handle local operations and a higher-level remote operator interface that handles coordination, allowing complexity to be distributed and managed at different levels rather than concentrated in one complex system
