In the whole process, the inlet end water supply pressure and the outlet end water supply pressure can be correlated, and the two target control amounts are regulated in real time through the controller, so that the aim of pump-pump decoupling is fulfilled, and the coupled water supply is realized.
In some embodiments, the method may further comprise: collecting inlet end water supply pressure through an inlet pressure sensor; the outlet end water supply pressure is collected by an outlet pressure sensor.
