The invention discloses a device and a method for automatically switching brake of a rail transit vehicle and a locomotive, which are characterized in that a mechanical double heading valve of the existing locomotive is replaced by a high-flow double-pulse change-over valve, so that automatic setting and switching of a locomotive double heading mode brake are realized through a brake microcomputer control unit; according to the whole system design, signal transmission and control are carried out through a microcomputer system, and the problem that the pressure of the brake cylinder of the locomotive cannot be established in time or is insufficient due to disconnection of an average pipe is solved; meanwhile, as the pressure of an action pipe of the multi-heading locomotive is discharged to the atmosphere through an average pipe, the pressure of a brake cylinder of the multi-heading locomotive cannot be established in time, and the major potential safety hazard that the disconnected leading locomotive and the multi-heading locomotive cannot be stopped safely in time is caused. In addition, corresponding protection measures used after the hook is broken during double heading operation of the locomotive are also arranged in a corresponding control pipeline system so as to ensure that braking is safely and reliably applied to stop after the hook of the locomotive is broken.
本发明公开了一种轨道交通车辆、机车制动机自动本补切换装置及方法,通过设置的大流量双脉冲转换阀替换既有机车的机械重联阀,实现通过制动机微机控制单元进行机车重联模式本补机的自动设置及转换,整个系统设计通过微机系统进行信号传递及控制,解决本务机车制动缸的压力因断开的平均管而不能及时建立或压力不足;同时,因重联机车的作用管压力经平均管排向大气,重联机车的制动缸压力也将不能及时建立导致断开后的本务机车和重联机车不能及时安全停车的重大安全隐患,另外也在相应的控制管路系统中设置有用于机车重联运行时发生断钩后的相应保护措施,以确保机车断钩后安全可靠的施加制动停车。
