| description | The invention discloses a variable-domain sprinkling irrigation method based on a measurement and control integrated valve, and belongs to the technical field of agricultural irrigation. The variable-domain sprinkling irrigation method comprises the steps that the adjustment error of the measurement and control integrated valve is set, and meanwhile the target range of a nozzle is set; the upstream pressure and the valve body opening degree of the measurement and control integrated valve are obtained, and the current range is calculated based on the upstream pressure and the valve body opening degree; judging the size relationship between the target range of the nozzle and the current range; a target opening value corresponding to the target range is calculated based on the size relation, and a corresponding electric pulse value is calculated based on the target opening value; and the measurement and control integrated valve is adjusted based on the corresponding electric pulse value, and the adjusted range i |
