Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods between locomotives and tender cars in train consists are insufficient for complex operations, particularly in multi-unit blended fuel scenarios, as they lack the capability to transmit detailed operational data and identification information, leading to inadequate control and response to fault conditions.
Innovation Solution
A communication method that transmits operational data and identification information between locomotives and tender cars, allowing for adjustments in operation based on capacity discrepancies and fault determinations, using a combination of MU cables, dedicated data links, and wireless communication to facilitate coordinated control and efficient fuel supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional MU cable communication is used between locomotives and tender car, then the communication system is simple and reliable, but the amount of information that can be transmitted is insufficient for complex multi-unit blended fuel operations
Solution Approach 1:
The patent combines multiple communication channels (MU cable for control signals, dedicated data link for operational data, and wireless communication for identification information) into a unified communication system. This merging approach allows the system to transmit comprehensive information including operational data, identification information, and control signals simultaneously, resolving the contradiction between information capacity and system complexity.
Solution Approach 2:
The communication system is designed with multi-functionality to handle various types of data transmission. The MU cable handles both traditional control signals and operational data, while the dedicated data link and wireless communication handle identification and operational information. This universal approach enables the system to transmit diverse information types without requiring separate dedicated channels for each, thereby increasing information capacity while managing complexity.
2Adaptability or versatility
If detailed operational data and identification information are transmitted between locomotives and tender car, then coordination for complex operations is improved, but the communication system becomes more complex
Solution Approach 1:
The patent segments the communication system into multiple functional channels: MU cable for control signals, dedicated data link for operational data, and wireless communication for identification information. This segmentation allows each channel to be optimized for its specific purpose, improving the system's ability to handle complex coordination tasks while keeping each individual channel relatively simple and manageable.
Solution Approach 2:
The patent introduces intermediary communication components (dedicated data link, wireless communication modules) that facilitate the transmission of operational data and identification information between locomotives and the tender car. These intermediaries enable detailed data exchange without requiring direct modification of the traditional MU cable system, thereby improving coordination capability while managing system complexity through modular additions.
3Productivity
If real-time communication is implemented for fuel supply control, then operational efficiency is improved, but the system requires more sophisticated communication infrastructure
Solution Approach 1:
The patent implements continuous communication between locomotives and the tender car through multiple channels that operate simultaneously. The MU cable continuously transmits control signals, the dedicated data link continuously exchanges operational data, and wireless communication continuously updates identification information. This continuous action enables real-time fuel supply control and operational adjustments, improving productivity while the distributed nature of multiple channels prevents any single point of complexity bottleneck.
