Technical Field
The invention relates to the technical field of rail trains, in particular to a method and a device for adjusting oxygen content of a cab of a power vehicle.
Background
In consideration of the fact that lines such as Qinghai-Tibet railways and Chuanghai-Tibet railways have higher altitude, in order to improve working environments of drivers and passengers, most locomotives, power cars and the like on the Qinghai-Tibet railways and Chuanghai-Tibet railways are provided with oxygen generators in drivers' cabs. The oxygen generator supplies certain oxygen to the cab to improve the oxygen content of the cab, so that the oxygen environment in the cab is improved for drivers and passengers. However, the existing scheme of additionally installing the oxygen generator cannot adjust the oxygen content in the cab, and cannot provide the optimum oxygen content environment for drivers and passengers. Because the drivers and passengers in the cab are usually located at different altitudes, when the oxygen concentration in the cab is lower, the drivers and passengers resident in a low altitude area are easy to generate an anoxic reaction; when the oxygen concentration in the cab is higher, drivers and passengers resident in the high altitude area can generate an oxygen intoxication reaction. Therefore, the oxygen content in the cab can be adjusted individually according to drivers and passengers, and the method has great significance.
