Water oxygen permeability measuring method, device, equipment and medium

The invention discloses a water-oxygen permeability measuring method, device and equipment and a medium, which are used for measuring the water-oxygen permeability value of a film to be measured based on numerical simulation and a particle swarm algorithm. The method comprises the following steps: acquiring real-time monitoring data detected by a mass spectrometer; determining a corresponding physical model according to the type of the to-be-tested film; on the basis of the physical model, adopting a numerical simulation algorithm to preprocess the real-time detection data so as to obtain pre-estimated values of related parameters and training samples; acquiring a range of a parameter sample space according to the related parameters, acquiring a test sample according to the training sample and the physical model, and performing parameter fitting by adopting a particle swarm algorithm according to the range of the parameter sample space, the training sample and the test sample, the water and oxygen permeabilit
