Autonomous Work Machine Direction Indicator for Mine Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no established technique for using a direction indicator in autonomous work machines to improve mine safety, despite its contribution to safety when used in manned vehicles.
Innovation Solution
A work machine management device that acquires position and operation data from manned vehicles with direction indicators to set and control blinker data for autonomous work machines, ensuring they follow a target travel route and indicate their direction effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous work machines operate in the same mine as manned vehicles, then productivity is improved through automation, but mine safety deteriorates due to lack of directional indication capability
Solution Approach 1:
The patent applies the copying principle by replicating the direction indicator system from manned vehicles to autonomous work machines. The autonomous machine is equipped with a direction indicator that copies the functionality of the manned vehicle's indicator, allowing other participants to understand the autonomous machine's traveling direction just as they would understand a manned vehicle's direction, thereby maintaining safety while enabling automation.
2Reliability
If direction indicators are added to autonomous work machines, then mine safety is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a direction indicator system that serves multiple functions: it indicates traveling direction to improve safety, and simultaneously operates as part of the autonomous navigation system. The indicator is integrated into the existing autonomous vehicle控制系统, allowing one system to fulfill both safety indication and navigation control roles, thereby reducing overall system complexity.

AI summary
A work machine management device includes a manned-vehicle-data acquisition unit configured to acquire position data of a manned vehicle including a first direction indicator and operation data of the first direction indicator, a target-travel-route generation unit configured to generate a target travel route for a work machine, a blinker-data setting unit configured to set blinker data for controlling a second direction indicator of the work machine on the basis of link data obtained by associating the position data of the manned vehicle and the operation data of the first direction indicator, and an output unit configured to output the blinker data to the work machine traveling along the target travel route.
