Brake control unit for railway vehicle

Abstract

The invention discloses a brake control unit for a railway vehicle. The brake control unit comprises a brake control part and an axle non-rotation detection part which are electrically independent of each other. The brake control part comprises a pneumatic brake control unit, a wheel sliding protection unit, an MVB network communication port and a serial port communication port. The axle non-rotation detection part comprises an axle speed anomaly detection unit, an MVB network communication port and a serial port communication port. The pneumatic brake control unit can conduct brake instruction receiving, brake force calculating, EP current control, EP current lag compensation control and the like. The wheel sliding protection module can conduct sliding and locking detection, sliding prevention and locking prevention control, tread sweeping control and ATC axle sliding state output. The axle speed anomaly detection unit judges whether a certain axle is locked or not or whether the speed of the axle is abnormal or not. The independent axle non-rotation detection part is arranged in the brake control unit, and therefore the working current of a speed sensor can be independently monitored and reported to a vehicle diagnosis device, and the safety level of the brake control unit is increased.

AI Technical Summary

Benefits of technology

This patented technology allows for better performance and efficiency during vehicles' operation compared to existing systems that use separate components like individual wheel sensors and hydraulic pressure regulators. It also includes redundancy between different levels of regulation such as train-to-train and section-based regulations. Additionally, there may be other functions provided separately from this module called Anti-Slip Control(ASC), which helps prevent slippages caused by excessive tire wear without affecting safe driving behavior. Overall, these technical features help ensure safer and more reliable automobile operations while ensuring efficient energy utilization.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance and reliability of EBCO units that are currently available but lacking any functionality related to their ability to accurately distribute and manage different types of forces during operation without losing its effectiveness due to failure modes such as lockup caused by incorrect wheel alignment.
