[0034] In step S1, a first oxygen concentration of an outlet of the oxygen mixer is obtained.

[0035] In step S2, if the first oxygen concentration is not in a preset concentration range, the opening degree of the first flow regulating valve is adjusted so that the oxygen concentration of the outlet of the oxygen mixer is in the preset concentration range. The preset concentration range can be 21.5% to 23.5%.

[0036] In some embodiments, after the first oxygen concentration of the outlet of the oxygen mixer is obtained, the method further comprises: if the first oxygen concentration is in the preset concentration range, the opening degree of the first flow regulating valve is not adjusted.

[0037] In some embodiments, the oxygen mixer further comprises a second inlet, the second inlet being connected to a nitrogen pipeline, the nitrogen pipeline being provided with a nitrogen on-off valve and a second flow regulating valve, and the nitrogen pipeline being connected to the oxygen pipeline. After the first oxygen concentration is not in the preset concentration range, the method further comprises: if the first oxygen concentration is greater than an upper limit value of the preset concentration range, a difference between the first oxygen concentration and the upper limit value of the preset concentration range is taken as a first concentration difference; if the first concentration difference is less than a first preset difference, the step of adjusting the opening degree of the first flow regulating valve is executed; if the first concentration difference is greater than or equal to the first preset difference and less than a second preset difference, a first valve opening degree is obtained based on a pre-established concentration opening degree mapping relationship according to the first concentration difference, the step of adjusting the opening degree of the first flow regulating valve is executed, the nitrogen on-off valve is opened, and the second flow regulating valve is opened at the first valve opening degree, the second preset difference being greater than the first preset difference, and the concentration opening degree mapping relationship comprising a plurality of concentration differences and a valve opening degree corresponding to each concentration difference.

[0038] Thus, if the first concentration difference is small, the opening of the first flow regulating valve is adjusted, if the first concentration difference is moderate, the opening of the first flow regulating valve is adjusted, and the nitrogen pipeline is also opened to dilute the oxygen in the oxygen pipeline.
