Cable Transport Vehicle Spacing Control via Individual Identification Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable transport installations face challenges in managing vehicle spacing, leading to uneven distribution and frequent shutdowns due to the inability to configure vehicles at varying distances, causing wear and discomfort for users.
Innovation Solution
Assigning individual identification codes to vehicles with associated setpoint values representing desired distances, allowing the control unit to dynamically control vehicle spacing at the timer section, enabling flexible positioning along the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the control unit operates in the first mode (filler mode) to continuously reposition vehicles towards their theoretical position, then vehicle positioning precision is improved, but timer means wear increases and user comfort deteriorates
Solution Approach 1:
The control unit operates in periodic cycles, alternating between filler mode (repositioning vehicles) and running mode (maintaining positions). This periodic operation reduces continuous actuation of timer means, decreasing wear while maintaining positioning precision over time.
Solution Approach 2:
The system maintains continuous vehicle distribution control by seamlessly transitioning between filler mode and running mode, ensuring that vehicle positioning is continuously optimized without requiring constant active repositioning, thereby reducing timer means wear.
2Reliability
If the control unit operates in the second mode (running mode) to reposition vehicles to the next theoretical position, then timer means wear is reduced, but installation shutdown frequency increases
Solution Approach 1:
The control unit dynamically switches between filler mode and running mode based on real-time vehicle distribution conditions. This dynamic operation allows the system to minimize shutdowns by using running mode only when necessary, while maintaining high timer means durability through reduced continuous actuation.
Solution Approach 2:
The control unit monitors vehicle positions and distribution continuously, using this feedback to determine when to switch between filler mode and running mode. This feedback mechanism ensures optimal balance between minimizing shutdowns and reducing timer means wear.
3Stability of the object's composition
If equal time intervals are imposed between all vehicles, then timing regularity is improved, but positioning flexibility deteriorates
Solution Approach 1:
The system applies different time intervals to different vehicles based on their specific conditions and positions. Instead of imposing a uniform time interval on all vehicles, the control unit assigns individualized intervals, allowing each vehicle to be positioned optimally while maintaining overall timing regularity.
Solution Approach 2:
The control unit dynamically changes the time interval parameter for each vehicle based on real-time conditions, vehicle type, and position requirements. This parameter variation enables flexible positioning while maintaining the regularity needed for safe and efficient operation.

AI summary
The method involves assigning an individual identification code to each vehicle e.g. gondola car, and associating a setpoint value representative of a required distance for the vehicle with the identification code. The individual identification code assigned to the vehicle is stored in a radio frequency tag installed onboard the vehicle. The individual identification code of the vehicle is integrated. The identification code disposed at an entry of a bottom terminal (11) and connected to a control unit is read. An independent claim is also included for a continuous running aerial ropeway transport installation.
