Title:
END FLOW REGULATION, MEASUREMENT AND REMOTE CONTROL APPARATUS FOR WATER-EFFICIENT IRRIGATION
Document Type and Number:
WIPO Patent Application WO/2023/173904
Kind Code:
A1
Abstract:
Disclosed in the present invention is an end flow regulation, measurement and remote control apparatus for water-efficient irrigation. The apparatus is composed of an irrigation head, a pipe network, flow regulation and measurement integrated apparatuses, photovoltaic energy supply apparatuses and remote intelligent control systems. One end of the pipe network is connected to the irrigation head, and the several flow regulation and measurement integrated apparatuses are mounted in the middle of the pipe network. Each flow regulation and measurement integrated apparatus is equipped with a corresponding photovoltaic energy supply apparatus and a corresponding remote intelligent control system. Each flow regulation and measurement integrated apparatus is composed of a valve body and a driving module, wherein the valve body regulates the flow by means of an opening degree thereof, the driving module is composed of a stepping electric motor and a speed reducer, and the driving module is used for driving a plunger to move so as to regulate the opening degree of the valve body. The remote intelligent control systems are a remote regulating valve opening degree decision-making module developed on the basis of Python, and the module measures and controls the opening degree of a regulating valve by using electric pulses. The apparatus can monitor and regulate and control the flow in an irrigation end pipe, has one-way and two-way water output forms, is highly flexible, is simple in terms of arrangement, runs independently and stably, can be operated remotely, and has a high degree of automation.
