Problems solved by technology

[0004] Aiming at the technical problem in the prior art that the train pipe pressure cannot be controlled due to a fault in the balance air cylinder pressure control, the present invention provides a locomotive brake control system, which can prevent the failure of the balance air cylinder pressure control leading to the train pipe pressure. When the pressure cannot be controlled, redundant control is performed on the train tube, thereby ensuring the braking performance of the locomotive and subsequent vehicles, and improving the safety and reliability of the railway vehicle

Abstract

The invention provides a locomotive brake control system, which comprises a train pipe brake control module and a brake cylinder brake control module. The train pipe brake control module comprises a first pressure control valve, an equalizing air cylinder, a first relay valve, and a train pipe which are successively connected; the brake cylinder module comprises a second pressure control valve, apre-control air cylinder, a second relay valve, and a brake cylinder which are connected successively; and the locomotive brake control system further comprises a train pipe redundant brake control module, wherein the train pipe redundant brake control module is connected between the equalizing air cylinder and the second pressure control valve. The invention further provides a locomotive brake control method. According to the locomotive brake control system and method, when pressure to the train pipe is out of control due to fault of pressure control of the equalizing air cylinder, the trainpipe is controlled redundantly, thus braking performance of locomotives and subsequent vehicles is ensured, and safety and reliability of railway vehicles are improved.

Description

technical field [0001] The invention belongs to the field of railway train braking control systems, and in particular relates to a locomotive braking control system and method. Background technique [0002] In the locomotive brake control system, by controlling the pressure value of the balance air cylinder, the pressure control of the train pipe is realized, and then the braking control of the subsequent vehicles is realized. Therefore, the reliability of the equalizing air cylinder pressure control directly affects the pressure control of the locomotive brake system on the train tube, and further affects the braking performance of the locomotive and subsequent vehicles. [0003] If the pressure control of the equalizing air cylinder fails, for example, the solenoid valve for filling and exhausting the equalizing air cylinder fails or the control module of the train pipe loses power, etc., the pressure input to the equalizing air cylinder cannot be controlled, which further...
