Problems solved by technology
[0004] However, in actual application, when a hydraulic unit component fails (such as sensor failure, valve failure, etc.), HCM and VSS cannot record the real time of the failure, which is not conducive to user troubleshooting and maintenance
At the same time, when the vehicle requires more functions for the hydraulic braking system, when the number of hydraulic valves and hard-wired commands increases, neither HCM nor VSS can achieve functional expansion and cannot meet the new needs.

The invention provides a hydraulic brake control device for a railway vehicle, which comprises a brake control module and a power supply conversion module. The brake control module is usedfor generating a brake control signal according to a vehicle brake instruction received from a train management system of the railway vehicle, performing closed-loop control according to the brake control signal to obtain a brake control feedback signal, adjusting the brake control signal according to the brake control feedback signal, and outputting the adjusted brake control signal to a hydraulic electromagnetic valve group and a hydraulic proportional valve group of the railway vehicle, so that the railway vehicle is braked; and the power supply conversion module is used for converting original 110V voltage output by a direct-current power supply on the railway vehicle into 24V power voltage for supplying power to the electromagnetic valve and the proportional valve. According to the invention, hydraulic braking control of the railway vehicle can be realized.
Description
technical field [0001] The present application relates to the technical field of rail vehicle brakes, in particular to a rail vehicle hydraulic brake control device. Background technique [0002] At present, many cities in my country have planned tram projects, among which low-floor trams are limited by space, and often use smaller hydraulic braking systems. At present, the major suppliers of hydraulic brake systems include Germany's Knorr and Hanning&Kahl. For vehicle structure and safety considerations, the hydraulic brake system has various types, hydraulic proportional valve group, 2-position 2-way valve, 2-position 3-way valve, pressure sensor and other configurations are changeable, among which the hydraulic proportional valve group is the core to adjust the hydraulic pressure Components, which directly affect the change of braking force through the magnitude of the current. [0003] Knorr's hydraulic electronic control module HCM is composed of power input, 3-way an...
