Remote Work Machine Control via Intermediary Command Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for reducing the cost of remote operation systems for work machines.
Innovation Solution
A remote operation system for work machines that includes a first operation device for transmitting operation commands via a first communication system, a second operation device for generating operation signals, and a remote controller that generates a second operation command based on the operation signal and outputs it to the first operation device via a second communication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote operation system is implemented for work machines, then operational flexibility and safety are improved, but system cost increases
Solution Approach 1:
The system is divided into separate functional modules: a first operation device for local control, a second operation device for remote control, and a remote controller that coordinates between them. This segmentation allows each component to be independently optimized and reduces overall system complexity while maintaining remote operation capability
Solution Approach 2:
The remote controller acts as an intermediary between the first operation device and the second operation device. It receives operation commands from either device, processes them appropriately, and executes them on the work machine. This intermediary approach enables seamless switching between local and remote operation modes without requiring a complete system redesign
2Reliability
If remote operation capability is added to work machines, then operational safety is improved, but device complexity increases
Solution Approach 1:
The remote controller is designed with multi-functionality, serving as both a receiver for operation commands and a coordinator between different operation devices. It can process commands from either the first or second operation device, eliminating the need for separate dedicated controllers for each operation mode and thereby reducing overall system complexity
