Work Vehicle Switchback Routing for Abnormal Loading Places
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a wide-area work site like a mine, if an abnormality occurs at a loading place, it is difficult for a work vehicle to quickly switch to a normal loading place, leading to decreased productivity.
Innovation Solution
A management system for a work vehicle that includes a traveling condition data generation unit, a specific area data acquisition unit, and a switchback command unit, allowing the vehicle to switch between forward and backward routes in a conveying path, enabling it to efficiently reroute around abnormal loading places.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the work vehicle travels to a loading place with abnormality, then the vehicle follows the normal operation procedure, but the productivity of the work site decreases
Solution Approach 1:
The system dynamically adjusts the traveling route based on real-time loading place status. When an abnormality is detected at a loading place, the management apparatus automatically generates and updates the traveling route to bypass the abnormal location, allowing the work vehicle to adapt its path dynamically rather than following a fixed route
Solution Approach 2:
The management apparatus continuously monitors the status of loading places and uses this feedback information to determine route adjustments. When abnormality information is received from a loading place, the system processes this feedback and generates updated traveling route information to redirect vehicles away from problematic areas
2Productivity
If the work vehicle quickly switches to a normal loading place, then the productivity is maintained, but the route switching complexity increases
Solution Approach 1:
The management apparatus performs multiple functions: it monitors loading place status, manages traveling routes, generates route adjustment commands, and communicates with work vehicles. This multi-functional system consolidates route switching complexity into a single centralized apparatus rather than requiring complex systems in each vehicle
Solution Approach 2:
The management apparatus acts as an intermediary between the loading places and work vehicles. It receives abnormality information from loading places, processes route adjustments, and transmits guidance to vehicles, thereby simplifying the overall system architecture by centralizing the decision-making logic
3Reliability
If the work vehicle travels a longer distance to avoid abnormal loading places, then the vehicle bypasses the problem area, but the travel time increases
Solution Approach 1:
The management apparatus pre-generates alternative traveling routes that bypass known abnormal loading places. By preparing these alternative routes in advance based on abnormality information, the system enables vehicles to switch to optimized paths without requiring real-time route calculation, thereby minimizing additional travel time

AI summary
A management system for a work vehicle, includes: a traveling condition data generation unit configured to set traveling condition data including a first traveling route for making a work vehicle travel with forward movement and a second traveling route for making the work vehicle travel with backward movement, in a conveying path leading to a workplace where an operation of the work vehicle is performed; a specific area data acquisition unit configured to acquire specific area data indicating a specific area where the work vehicle is able to switch back in the conveying path; and a switchback command unit configured to output a command signal for switching back the work vehicle traveling on one of the first traveling route and the second traveling route at the specific area, and making the work vehicle travel on the other of the first traveling route and the second traveling route.
