Water-saving irrigation tail end flow regulation, measurement and remote control device

Abstract

The invention discloses a water-saving irrigation tail end flow regulation, measurement and remote control device which is composed of an irrigation head, a pipe network, a flow regulation and measurement integrated device, a photovoltaic energy supply device and a remote intelligent control system. One end of the pipe network is connected with the irrigation head, a plurality of flow adjusting and measuring integrated devices are installed in the middle of the pipe network, each flow adjusting and measuring integrated device is provided with a corresponding photovoltaic energy supply device and a corresponding remote intelligent control system, each flow adjusting and measuring integrated device is composed of a valve body and a driving module, and the valve body adjusts flow through the opening degree. The driving module is composed of a stepping motor and a speed reducer, the driving module is used for driving the plunger to move and adjust the size, the remote intelligent control system is a remote adjusting valve opening degree decision-making module developed based on python, and the adjusting valve opening degree is metered and controlled through electric pulses. The device can monitor, regulate and control the flow of the irrigation tail end pipeline, has a unidirectional and bidirectional water outlet form, and is high in flexibility, simple in arrangement mode, independent and stable in operation, capable of being remotely operated and high in automation degree.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation devices, and relates to a water-saving irrigation terminal flow adjustment, measurement and remote control device. Background technique [0002] The irrigation end pipe network is the last system unit for the irrigation water to go to the farmland. In this part of the pipe network, the flow of the pipeline is regulated, and it is a key means to improve the refinement of the irrigation system. At the same time, precision agriculture and smart agriculture have been popularized on a large scale because of their advantages of water saving, labor saving, yield increase, greenness and high degree of automation. In line with this trend, it is necessary to design and develop the remote control and management device for the flow of the irrigation end pipe network. [0003] The flow adjustment methods of most irrigation systems currently in operation mainly include the following methods: ad...

Problems solved by technology

[0003] The flow adjustment methods of most irrigation systems currently in operation mainly include the following methods: adjusting the speed of the water pump in the pump room or arranging multiple water pumps to regulate the water pressure of the system, which has a certain flow adjustment effect, but the system has low flexibility and costs. Higher; setting manual valves in the end pipe network to change the flow of irrigation branch pipes, this method has a low degree of automation, and the flow adjustment is not stable and timely

There are two states of remote solenoid valve fully closed and fully closed in the market, which cannot adjust the flow rate or measure the flow rate, and cannot meet the needs of farmers for precise irrigation of the end pipe network.

[0004] Therefore, there is a need for a flow regulating device installed in the irrigation end pipe network to solve the problem of insufficient flexibility of the irrigation system; develop a flow measurement and flow regulation strategy to achieve fine management of pipeline flow; optimize the remote control scheme to form Independent remote control module with photovoltaic power supply, simple layout and stable operation
