Work and life under the environment have great influence on the functions of the human body, oxygen deficiency reduces the oxygen content in blood, the workload of a cardiovascular system is increased, and long-term oxygen deficiency can cause organs to be diseased. And meanwhile, the brain tissue cells are damaged by hypoxia, so that the energy metabolism of the whole tissue cells is obstructed, and then cell degeneration and necrosis occur. The hard and bad natural conditions have great damage to the human body functions, influence the normal exertion of the human body functions, and influence the working efficiency when being in a sub-health state for a long time. Because oxygen is an indispensable element for the life activities of human bodies, people who are in an anoxic state for a long time are firstly reduced in immunity, susceptible to cold and reduced in exercise endurance. For people working in high altitude areas for a long time, various serious influences can be caused, especially the damage of the functions of organs such as heart, lung, brain and the like, and the normal life and working state of the people are seriously influenced by the problems.

At present, in order to solve the problem of oxygen deficiency in plateau, many researchers and manufacturers have proposed a plurality of practical oxygen supply technologies and oxygen supply equipment, which mainly aim at solving the problem of oxygen deficiency in plateau, but do not comprehensively consider the huge influence caused by the oxygen deficiency in the plateau and the low-temperature environment, and such oxygen supply equipment obviously has the outstanding defects of high cost, inconvenience in carrying and the like, so that the utilization and development of the oxygen supply equipment in the life of people in the plateau area are also limited.

When the hot demand of the personnel of sitting in the seat and the oxygen demand change, the hot oxygen joint control air supply seat of high altitude area railway station room can carry out corresponding regulation according to personnel actual conditions:
if the oxygen demand and the heat demand of the sitting personnel are increased, the opening range of the oxygen concentration regulating valve 35 of the controllable hot oxygen mixing heating box 1 is increased, meanwhile, the opening range of the fan flow regulating valve 33 of the controllable hot oxygen mixing heating box 1 is decreased, at the moment, the oxygen concentration of the mixed gas in the controllable hot oxygen mixing heating box 1 can be increased, the real-time oxygen concentration value of the gas can be read through the display 31 on the control cabinet 30, and the adjustment can be carried out according to different oxygen demands of the personnel; meanwhile, the opening amplitude of the temperature regulating valve 34 is increased, the oxygen and the air are uniformly mixed and then continuously heated by the heating coil 33, the temperature of the mixed gas is gradually increased, and at the moment, the gas temperature value can be read by the display 31 on the control cabinet 30, so that corresponding regulation can be carried out according to different heat requirements of personnel; the air after the mixed heating is sent out from the air supply outlets after passing through the air outlet main pipe 22 and the air outlet branch pipes, the air outlet air velocity can be controlled in a reasonable range through adjusting the air supply adjusting valves of the air supply outlets, and the comfort of the sitting personnel of the seat is ensured.
If the oxygen demand and the heat demand of the sitting personnel become low, the opening range of the oxygen concentration regulating valve 35 of the controllable hot oxygen mixing heating box 1 is reduced or closed, meanwhile, the opening range of the fan flow regulating valve 33 of the controllable hot oxygen mixing heating box 1 is increased, the oxygen concentration of the mixed gas is gradually reduced, the oxygen concentration value is read through the display 31 on the control cabinet 30, and the oxygen concentration value can be regulated according to the requirement of the personnel; simultaneously temperature regulating valve 34 opens the range and diminishes, and heating coil 3 heating time shortens, and the mist temperature reduces gradually this moment, and the temperature value shows on switch board 30's display 31, adjusts according to personnel's hot demand. The air outlet air speed is controlled in a reasonable range through the air supply regulating valve, and the requirements of different personnel are met.
When no person sits on the seat, the switch of the heating coil 3 in the controllable hot oxygen mixing heating box 1 is closed, other flow regulating valves are closed, the controllable hot oxygen mixing heating box 1 is in a non-running state, and the purpose of saving energy of the system can be achieved.
