An Intelligent Irrigation Method for Condition Control

Abstract

According to the pipe condition control intelligent irrigation method of the present invention, the electric valve opening control device receives the fluid information in the pipe from the pipe condition detection sensor, and drives the spool of the electric valve to rotate to a suitable valve opening according to the preset fluid information. Accurately control the water volume, pressure and flow rate in the hose, realize precise water and fertilizer irrigation, and avoid problems such as pipe detachment or pipe burst, water hammer phenomenon, water and fertilizer waste, and water and fertilizer corrosion of the pipe wall caused by pressure differences. It is convenient to establish a blockchain agricultural management system, making nationwide intelligent agricultural management possible. And the sensing element of the pipe condition detection sensor extends into the hose through the probe protection structure; the structure is simple and reliable, and the installation is convenient, and the sensing element is protected from impact damage on the basis of effectively obtaining fluid information in the pipe , which greatly reduces the detection cost of the intelligent irrigation system and facilitates the promotion and application of large areas.

Description

technical field [0001] The invention relates to the technical field of intelligent irrigation valves, in particular to an intelligent irrigation method for condition control. Background technique [0002] The shortage of water resources has become a global problem. Saving water and achieving efficient water use is the need for human survival and development, as well as the needs of the global economy and society. Water resources are likely to be another scarce resource faced by human beings after petroleum resources. This is a reality that we cannot avoid. As one of the water-poor countries, our country has a large population and is in the period of economic construction and development, so the demand for water resources is increasing day by day. Since agricultural water accounts for 70% of my country's total water consumption, and the problems of low agricultural irrigation efficiency and water waste are common, the contradiction between water shortage and the increase of ...

Problems solved by technology

[0003] The existing automatic agricultural irrigation machinery, especially the automatic control of the irrigation valve, adopts the solenoid valve control, but the solenoid valve needs a certain pressure to start, and it is controlled by the switch, which can only realize the opening and closing of the valve body. , especially in drip irrigation operations, the control of pipeline pressure depends on human experience, which is very random, and there is no scientific data support in the entire irrigation process. The phenomenon of pipe rupture or pipe burst will lead to random irrigation water and fertilization, low utilization rate of water and fertilizer, serious waste of resources (the utilization rate of water and fertilizer is only about 40%), and long-term random control will cause soil structure damage and environmental pollution. agricultural planting issues
