Abstract

The invention belongs to the field of locomotive brake control and relates to a locomotive brake control system and control method. The locomotive brake control system comprises an average pipe control system and a brake cylinder control system, wherein the average pipe control system can compare the brake cylinder pre-control pressure with the average pipe pre-control pressure, and outputs a large pressure as the average pipe pressure, the brake cylinder control system can compare the brake cylinder pre-control pressure with the average pipe pressure and output large pressure to serve as thebrake cylinder pressure to achieve braking. The locomotive brake control system is advantaged in that redundancy of two control systems can be realized.

Description

technical field [0001] The application relates to a locomotive brake control system and a control method, belonging to the field of locomotive brake control. Background technique [0002] One of the important functions of the locomotive brake control system is to control the pressure of the average pipe and the brake cylinder. The conventional method is to control the pre-control pressure through the high-frequency solenoid valve, and then output the average pipe consistent with the pre-control pressure through the relay valve or Brake cylinder pressure, in order to avoid the impact of the average pipe and brake cylinder control failure on the operation of the locomotive, the pre-control pressure control part that is prone to failure is usually backed up. [0003] The existing locomotive brake control systems are mainly CCBII and Eurotrol. Both of these two brake control systems use mechanical air distribution valves to make redundant the pressure pre-control part of the bra...
