The invention discloses a multi-locomotive reconnection locomotive and an electric-pneumatic cooperation control method and system.The method comprises the steps that the current brake cylinder pressure value and the current deceleration are determined according to a brake level signal of an electric control handle, and then an air braking force demand value and target speeds generated when the speeds of all slave control locomotives are reduced to electric-pneumatic conversion are determined; the air braking force demand value and the target speed of each slave control vehicle are sent to the corresponding slave control vehicle CCU; and when the speed of the master control vehicle or the slave control vehicle is reduced to the corresponding target speed, the master control vehicle CCU sends an electric braking force fading signal to the master control vehicle BCU or the slave control vehicle CCU sends an electric braking force fading signal to the corresponding slave control vehicle BCU. According to the method, the main control vehicle BCU does not need to send an electric braking force fading signal to each slave control vehicle BCU, and transmission delay caused by the fact that the electric braking force fading signal is sent to each slave control vehicle BCU from the main control vehicle BCU is avoided.
本发明公开了一种多机重联机车及其电空配合控制方法与系统,所述方法包括根据电控手柄的制动级位信号确定当前制动缸压力值和当前减速度,进而确定空气制动力需求值和各从控车速度下降至电空转换时的目标速度,将空气制动力需求值、各从控车的目标速度发送给对应的从控车CCU;当主控车或从控车的速度下降至对应的目标速度时,由主控车CCU向主控车BCU或从控车CCU向对应从控车BCU发送电制动力消退信号。本发明无需主控车BCU向各从控车BCU发送电制动力消退信号,避免了电制动力消退信号由主控车BCU发送给各从控车BCU导致的传输延迟。
