Construction Machine Auto-Start Confirmation via Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic operation construction machines risk unintended vehicle movement during mode transitions due to remote control misinterpretation, posing a safety hazard for operators who may not recognize the start of automatic operations.
Innovation Solution
An automatic operation construction machine with a controller that requires multiple operations of a remote control device to initiate automatic mode, ensuring the machine body remains stationary until confirmed by the operator, and includes sensors and communication devices to manage control states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the machine body control state is switched from manual control state to automatic control state by the switching device, then the automatic operation can be initiated, but the machine body may move immediately without the operator's awareness, causing safety hazards
Solution Approach 1:
The controller sets the automatic control inactive state when switching from manual to automatic control mode, requiring multiple remote control operations before the machine body can move. This preliminary action ensures the operator has time to recognize and prepare for automatic operation startup, preventing unintended movement while maintaining automation capability
Solution Approach 2:
The system provides feedback through the requirement of multiple remote control operations (at least two operations) to transition from inactive to active automatic control state. This feedback mechanism confirms the operator's intent and ensures awareness of the mode transition, enhancing safety while enabling automatic operation
2Productivity
If the machine body allows immediate operation in automatic mode after mode switching, then operational efficiency is improved, but the operator cannot recognize the start of automatic operation in time, leading to potential interference with the vehicle body
Solution Approach 1:
By requiring multiple remote control operations before activating automatic control, the system creates a time buffer that allows the operator to exit the vehicle safely. This preliminary action sequence maintains productivity by enabling automatic operation while preventing the harmful effect of immediate unintended movement

AI summary
Provided is an automatic operation construction machine that allows an operator to recognize in advance a start of the operation in an automatic mode when the operator switches a mode and leaves a machine body. A controller (40) does not start the operation of the machine body in an automatic control state until a remote control device (800) is operated a plurality of times in the automatic control state and the state where the operation of the machine body has not started, and the operator near the machine body is able to recognize that a non-final procedural operation, which is a non-final operation among the plurality of operations of the remote control device (800), is performed.
