Work Site Vehicle Coordination for Discharge Path Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In work sites where manned and unmanned vehicles operate together, the smooth operation of unmanned vehicles is hindered when the discharging position of a manned vehicle overlaps with the travel path of the unmanned vehicle, leading to potential collisions or operational disruptions.
Innovation Solution
A system that includes an identification unit to determine the discharging position of manned vehicles and an operation control unit to adjust the travel course of unmanned vehicles, ensuring they avoid the discharging position to prevent collisions and maintain smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver discharges cargo to any position freely, then the ease of operation is improved, but the reliability deteriorates due to potential overlap with unmanned vehicle paths
Solution Approach 1:
The management device receives position information from both the manned vehicle and unmanned vehicles, continuously monitors their relative positions, and provides feedback control by notifying the manned vehicle when the discharging position overlaps with unmanned vehicle paths, enabling real-time adjustment to prevent collisions
Solution Approach 2:
The management device acts as an intermediary between the manned vehicle and unmanned vehicles, coordinating their operations by processing position data from both sources and communicating necessary avoidance information to the manned vehicle driver
2Device complexity
If the discharging position is not monitored, then the device complexity is reduced, but the productivity deteriorates due to operational disruptions
Solution Approach 1:
The management device performs multiple functions including position information reception from both manned and unmanned vehicles, overlap determination between discharging positions and travel paths, and notification to the manned vehicle, thereby improving productivity without requiring separate dedicated systems for each function

AI summary
A system for managing a work site includes: an identification unit that identifies a discharging position of a manned vehicle in the work site where an unmanned vehicle and the manned vehicle operate in a mixed manner; and an operation control unit that controls operation of the unmanned vehicle based on the discharging position.
