Work Machine Control for Interrupting Task Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for work machines struggle with handling sudden interrupting tasks, requiring a reset of the on-site environment and work machine settings, making it difficult to manage such tasks effectively.
Innovation Solution
A control system for work machines that prioritizes and performs interrupting tasks after completing the current task, utilizing a work instruction acquisition section and action control section to handle interrupting tasks efficiently by transferring them to the current task buffer after non-interrupting tasks are completed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control system performs a reset of the on-site environment and work machine setting to handle an interrupting task, then the interrupting task can be handled, but the operation becomes complicated and time-consuming
Solution Approach 1:
The control system stores the on-site environment information and work machine settings in a buffer before the interrupting task occurs. When the interrupting task is completed, the system automatically restores the previously stored environment and settings, eliminating the need for manual reset operations and reducing operational complexity.
2Adaptability or versatility
If the control system performs a reset of the on-site environment and work machine setting to handle an interrupting task, then the interrupting task can be handled, but time is lost due to resetting
Solution Approach 1:
The system performs preliminary storage of environment and setting data in a buffer before the interrupting task occurs. This pre-preparation allows for immediate restoration after the interrupting task, eliminating time-consuming reset operations and enabling quick transition back to the original workflow.
3Productivity
If the control system automatically positions and excavates without manual intervention, then productivity increases, but the system cannot easily adapt to sudden work instructions
Solution Approach 1:
The control system dynamically switches between automatic execution mode and interrupt handling mode. When an interrupting task is detected, the system pauses the automatic workflow, processes the interrupting task using the buffered environment information, and then resumes the automatic workflow, thereby maintaining both high productivity and adaptability to sudden changes.
Solution Approach 2:
The buffer serves as an intermediary that stores environment and setting information. This intermediary allows the system to quickly restore previous states when interrupting tasks occur, enabling the automatic system to adapt to sudden work instructions without losing its automated efficiency.
Data Source
AI summary
A control system 200 for a work machine includes a communication interface 18 that acquires a series of work instructions to a work machine 1 and an action control section 110 that controls an action of the work machine 1 so as to perform tasks included in the work instructions acquired by the communication interface 18. When the tasks included in the work instructions include an interrupting task to be preferentially performed and non-interrupting tasks other than the interrupting task, the action control section 110 performs the interrupting task after performing an action of the work machine 1 instructed by a task in execution.
