The gaseous oxygen supply system comprises an oxygen source module, an outlet of the oxygen source module is connected with an air inlet busbar through a valve, one path of the air inlet busbar is connected with a decision control module, one end of the decision control module is provided with an oxygen partial pressure sensor, and the other end of the decision control module is provided with an oxygen supply module. The other path of the air inlet busbar is connected with a protection valve, an outlet of the protection valve is connected with an oxygen source switching valve through a pipeline, an outlet of the oxygen source switching valve is divided into an upper pipe and a lower pipe which are connected in parallel, and the upper pipe is sequentially connected with an air inlet valve, a pressure reducing valve, a low pressure gauge, a normally-open electromagnetic valve, a flow adjusting valve and a check valve in series. An air inlet valve, a pressure reducing valve, a low pressure gauge, a flow regulating valve and a stop check valve are sequentially connected to the lower pipe in series, outlets of the check valve and the stop check valve are simultaneously connected with an air outlet busbar, and the air outlet busbar is connected with the oxygen outlet through an oxygen outlet stop valve. The closed breathing function under the severe environment is achieved, and the oxygen supply safety and reliability are high.
