Title:
FLOW CONTROL METHOD, APPARATUS AND SYSTEM FOR LIQUID EXTRACTION APPARATUS OF PLANT PROTECTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/119190
Kind Code:
A1
Abstract:
A flow control method for a liquid extraction apparatus (22, 33) of a plant protection machine (21, 31). The control method comprises: acquiring a target flow of an extraction liquid; determining, based on a pre-set association relationship, the rotation speed, corresponding to the target flow, of a liquid extraction apparatus, wherein the pre-set association relationship is a relationship between the flow and the rotation speed of the liquid extraction apparatus; and controlling the liquid extraction apparatus so that same rotates at the rotation speed so as to extract the liquid. In a flow control system to which the control method is applied, the liquid extraction apparatus is mounted on a ground station (32), and the liquid extraction apparatus comprises one or more processors (13, 223, 333) for acquiring the target flow of an extraction liquid, determining the rotation speed, corresponding to the target flow, of the liquid extraction apparatus, and controlling the liquid extraction apparatus so that same rotates at the rotation speed. The control method and system can accurately control a flow.
