Title:
FLOW VALVE CONTROL METHOD AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/129058
Kind Code:
A1
Abstract:
A flow valve control method and apparatus, and a storage medium. The flow valve control method comprises: conducting self-learning of a median current value of a flow valve starting from an initial median current value of the flow valve (S100); and correcting a flow-current curve of the flow valve based on a deviation value obtained by the self-learning (S200). Each process of self-learning comprises: controlling a current output to a flow valve, so that the flow valve goes through the following processes successively: when there is a flow passing through, an output flow enables a shifting mechanism to return to position, and when there is a flow passing through again, an output flow again enables the shifting mechanism to return to position (S110); recording a current value the twice when there is a flow passing through the flow valve as a maximum median current value (S120); and acquiring a deviation value of the maximum median current value from the initial median current value (S130). By means of a self-learning control strategy, the median current value of the flow valve is constantly corrected to obtain a precise current-flow curve, so that the aim of precisely controlling the flow valve can be reached.
