The invention provides a railway vehicle cab oxygen supply system and an oxygen supply method thereof. The railway vehicle cab oxygen supply method comprises the steps that when an oxygen generator monitors that the pressure of compressed air conveyed by an air compressor is greater than a set value, and after a normal working signal of an air conditioning unit is obtained, the oxygen generator outputs oxygen with the concentration A in a diffuse type oxygen supply mode; meanwhile, the oxygen generator outputs oxygen with the concentration B in a distributed oxygen supply mode; and when the oxygen generator monitors that the pressure of compressed air conveyed by the air compressor is lower than a set value and after the signal that the air conditioning unit does not work is obtained, the diffuse type oxygen supply mode of the oxygen generator is closed, a standby compressor in the oxygen generator is started to provide a compressed air source, and the oxygen generator outputs oxygen with the concentration B in a distributed oxygen supply mode. Compared with the prior art, oxygen generation in the cab can be switched between a dispersion and distributed oxygen supply combination mode and a distributed oxygen supply mode according to the compressed air pressure value of the trailer.
本发明提供一种轨道车辆司机室供氧系统及其供氧方法。所述轨道车辆司机室供氧方法包括:制氧机监测到空压机输送的压缩空气的压力大于设定值时,且得到空调机组正常工作信号后,制氧机以弥散式供氧模式输出A浓度的氧气;同时,制氧机还以分布式供氧模式输出B浓度的氧气;制氧机监测到空压机输送的压缩空气的压力小于设定值时,且得到空调机组未工作信号后,关闭制氧机的弥散式供氧模式,启动制氧机内部的备用压缩机提供压缩气源,制氧机以分布式供氧模式输出B浓度的氧气。与相关技术相比,本发明能使司机室制氧能根据拖车压缩空气压力值在弥散+分布式供氧组合与分布式供氧两种方式中切换。
