Innovation Solution
A brake control system for rail trains comprising vehicle brake control units, train brake control units, traction control units, and communication control units, which communicate through gateways and multifunction vehicle buses, allowing for centralized management of air and electric braking forces based on real-time weight and speed data, enabling flexible train formation and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed formation brake control system is used, then the braking structure and control method are simple and stable, but the system cannot adapt to flexible train formation changes and diversified passenger flows
Solution Approach 1:
The brake control system is segmented into multiple independent vehicle brake control units (VBCU), each capable of autonomous control. This segmentation allows the system to adapt to different train formations by dynamically configuring which units are active, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The system implements dynamic brake force distribution based on real-time train formation configuration. The brake control units can dynamically adjust braking forces according to the actual number and arrangement of vehicles, enabling flexible formation adaptation without requiring a complete system redesign.
2Ease of operation
If traditional air braking through train pipe is used, then the braking system is simple and reliable, but the system cannot perform advanced control on braking force distribution
Solution Approach 1:
The patent replaces the traditional mechanical air pipe-based brake control with an electronic control system. Vehicle brake control units (VBCU) use electronic signals and communication networks to precisely control braking forces, substituting the simple but imprecise mechanical system with a more complex yet controllable electronic system.
Solution Approach 2:
The brake control system incorporates feedback mechanisms where VBCU units continuously monitor braking status and adjust brake forces accordingly. This feedback loop enables precise control of braking force distribution across different vehicles, improving ease of operation through automated adjustment.
3Productivity
If centralized brake control is used in fixed formation, then the control process is simple, but the system cannot calculate and distribute braking force according to changing train configurations
Solution Approach 1:
The centralized control function is segmented and distributed to individual vehicle brake control units. Each VBCU can independently calculate and execute braking force distribution for its associated vehicles, improving both productivity through parallel processing and adaptability through decentralized decision-making.
Solution Approach 2:
The system performs preliminary configuration of brake control parameters based on expected train formations. When formation changes occur, the VBCU units can quickly adapt using pre-configured parameters, improving response time and maintaining high productivity during configuration transitions.
