Problems solved by technology

[0004] The current backup mode mostly uses a purely mechanical method to control the locomotive brake, that is, it is completely manual operation, and cannot achieve hot backup redundancy of the double-section locomotive brake, which affects the reliability and availability of the locomotive.

Embodiment Construction

[0043] The core of the present invention is to provide a locomotive brake control method and system, which adopts a double-section locomotive brake hot standby redundant control mode to realize locomotive brake control.

[0044] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] Please refer to figure 1 , figure 1 It is a flow diagram of the locomotive brake control method provided by the embodiment of the present invention. This method is applied to the locomotive brake control system installed on the double-section locomotive. For the system structure diagram, please refer to figure 2 , the locomotive brake control system includes: a first braking system and a second braking system connected through MVB (Multifunction Vehicle Bus, locomotive network), the first braking system is...

Abstract

The invention discloses a locomotive brake controlling method and system. The locomotive brake controlling method includes that when a first carriage serves as an operating carriage, a first CCU (central control unit) detects that the fault occurs to the first carriage and then controls a first redundant device to start; a first braking controller generates a braking command and a state confirming message which are corresponding and sends the braking command and the state confirming message to the first redundant device; the first redundant device receives the braking command and the state confirming message and sends the same to a second BCU (basic communication unit) of a second carriage which is a non-operating carriage through an MVB (multifunction vehicle bus); the second BCU receives the braking command and the state confirming message through the MVB and responds to the braking command. In this way, the non-operating carriage functions in braking in the case that the fault occurs to the brake of the operating carriage, the hot spare redundant function of the brake of the double-carriage locomotive is achieved, and the locomotive is more reliable and available.

Description

technical field [0001] The invention relates to the technical field of railway traffic, in particular to a method and system for controlling a locomotive brake. Background technique [0002] At present, railway technology is developing rapidly, and the demand for double-section locomotives is increasing day by day, such as the DC drive freight electric locomotive model SS4G / SS4B, the Shenhua eight-axis high-power AC rotating freight electric locomotive and the high-power AC rotating electric locomotive model HXD1 Freight electric locomotives, etc. Among them, the HXD1 electric locomotive is an eight-axle heavy-duty freight electric locomotive composed of two identical four-axle electric locomotives connected through an inner reconnection link. Each car has a driver's cab, which is a complete system. [0003] Now during the braking operation of the double-section locomotive, when the operating locomotive manufacturing machine fails, the double-section locomotive will not be ...
