Abstract

The invention discloses a control method and device for a gas circuit switching mechanism of an oxygen generator. Wherein, the control method of the gas circuit switching mechanism of the oxygen generator includes: determining the reference pressure of the gas circuit switching mechanism of the oxygen generator; determining the reference time for switching the gas circuit switching mechanism of the oxygen generator; according to the reference pressure and The reference time adjusts the control parameter to determine the optimal value of the control parameter. Through the present invention, the gas path switching mechanism of the oxygen generator can be easily controlled.

Description

technical field [0001] The invention relates to the field of control, in particular to a method and device for controlling a gas circuit switching mechanism of an oxygen generator. Background technique [0002] In traditional molecular sieve oxygen generators, the control of the gas circuit switching actuator directly affects the oxygen production rate of the oxygen generator. [0003] At present, the methods used by such products to realize process control are generally divided into two methods: voltage control and time control. In these two kinds of controls, once the control parameters are determined, the control process is also determined, and the control parameters are finally determined through calculation and experiment during the prototype design and development process. During production, no further changes are made. [0004] During the production and processing of molecular sieve oxygen generator equipment, not only the gas circuit control process has an impact o...
