Remote Control System Abnormality Detection via Functional Unit Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for vehicles in manufacturing processes lack effective abnormality detection, leading to unstable vehicle control when functional units malfunction, potentially causing movement issues.
Innovation Solution
A remote control system where functional units, including a route planning unit and a moving object identifying unit, detect abnormalities by exchanging information and can reduce the moving speed or limit the steering angle of the vehicle when an abnormality is detected, ensuring more stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functional units operate independently without abnormality detection, then system complexity is reduced, but reliability deteriorates due to inability to detect and respond to malfunctions
Solution Approach 1:
Each functional unit receives feedback information from other functional units to detect abnormalities. The route planning unit receives position information from the moving object identifying unit, and the moving object identifying unit receives route information from the route planning unit, enabling mutual abnormality detection through feedback loops.
Solution Approach 2:
The system performs preliminary abnormality detection before malfunctions affect vehicle movement. By continuously monitoring information exchange between functional units, the system can detect potential failures early and take preventive actions to maintain reliable operation.
2Reliability
If abnormality detection is implemented through information exchange between functional units, then reliability improves, but information processing complexity increases
Solution Approach 1:
The functional units serve multiple functions: they not only perform their primary tasks (route planning and position identification) but also simultaneously detect abnormalities in other units by processing exchanged information. This multi-functionality reduces the need for separate dedicated detection components.
Solution Approach 2:
The abnormality detection function is merged with the existing information exchange mechanism between functional units. The same information channels used for normal operation (route planning to movement control) are also utilized for abnormality detection, combining multiple functions into a single integrated system.
3Object-affected harmful factors
If the system reduces moving speed or limits steering angle upon abnormality detection, then safety improves, but productivity decreases due to movement restrictions
Solution Approach 1:
The system dynamically adjusts vehicle movement parameters based on the severity and location of detected abnormalities. The control unit can selectively apply speed reductions or steering angle limitations only when and where abnormalities are detected, rather than imposing uniform restrictions on all movements, thereby maintaining productivity when system operation is normal.
