Remote-Control Vehicle Routing for Unstable Factory Track Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote control systems lack the ability to dynamically adjust the running route based on real-time track conditions, such as weather, construction, and communication state, leading to potential instability and accidents during unmanned driving.
Innovation Solution
A system comprising a remote controller, a vehicle communication unit, a track information acquisition unit, and a running method determination unit that uses acquired track information, including weather, construction, and communication state, to determine an appropriate running method and route for the vehicle, utilizing cameras and external data sources to assess light conditions and aerosol impact on image recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle runs by remote control along a fixed track, then the manufacturing process can proceed, but the system cannot adapt to changing track conditions such as weather, construction, or communication issues
Solution Approach 1:
The system performs preliminary assessment of track conditions (weather, construction, communication state) before the vehicle starts running. The determination unit evaluates multiple track conditions in advance and selects an appropriate running method or route, preventing the vehicle from entering hazardous areas and ensuring safe operation without requiring complex real-time adjustments during movement
Solution Approach 2:
The system dynamically selects running methods and routes based on real-time track conditions. The determination unit can choose from multiple running methods (autonomous driving, remote control, stopping) and multiple candidate routes, adapting the vehicle's operation to match current environmental conditions, communication quality, and track safety status
2Reliability
If the vehicle operates in areas with poor image recognition conditions, then the vehicle can maintain movement, but image analysis troubles occur reducing control reliability
Solution Approach 1:
The determination unit evaluates image recognition conditions (lighting, aerosol, camera angle) before the vehicle enters problematic areas. By assessing these conditions in advance, the system can pre-select alternative routes with better recognition conditions or adjust running methods, ensuring reliable remote control operation while maintaining vehicle productivity through proactive route planning
Solution Approach 2:
The determination unit acts as an intermediary between the vehicle control system and environmental conditions. It processes multiple track condition parameters (including image recognition conditions) and translates them into appropriate running method selections, mediating between the conflicting requirements of operational continuity and control reliability
3Reliability
If the vehicle runs without assessing communication state, then the vehicle can maintain its schedule, but remote control stability deteriorates leading to potential accidents
Solution Approach 1:
The system performs preliminary assessment of communication state (radio field strength, channel utilization) before the vehicle begins its journey. The determination unit evaluates communication quality in advance and selects running methods or routes that ensure stable remote control operation, preventing accidents caused by poor communication while minimizing schedule delays through proactive planning
