Intelligent green land spraying irrigation system and method capable of automatically regulating irrigation intensity in real time

Abstract

The invention discloses an intelligent green land spraying irrigation system and method capable of automatically regulating the irrigation intensity in real time. The system comprise a sprayer module,an electric regulating valve module and the like, wherein the sprayer module consists of uniformly distributed sprayers used for spraying water onto green land; a sensor module comprises a humidity sensor, a flow rate sensor and a pressure sensor which are respectively used for sensing the soil humidity and the flow rate and pressure in an irrigation pipeline and transmitting signals to a controller; a control module firstly judges whether the spraying irrigation is needed or not according to the soil humidity, and then calculates the soil infiltration speed; the spraying irrigation intensityis determined according to 0.9 time of the soil infiltration speed; the water outlet quantity of a single sprayer is calculated according to the spraying irrigation intensity and the service area; then the opening degree of an electric regulating valve is determined, the electric regulating valve is opened, and the water outlet quantity of the sprayers is controlled to cause the change of the flow rate and the pressure in a pipe network of the spraying irrigation system; the flow rate and pressure data is fed back to the control module in real time; and the precise intelligent variable-frequency spraying irrigation is realized. The system and the method provided by the invention have the advantages that the structure is simple; scientificity and safety are realized; and water consumption,labor consumption and energy source consumption can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of municipal engineering landscaping and sponge city, and in particular relates to an intelligent green space sprinkler irrigation system and method capable of automatically adjusting the intensity of sprinkler irrigation in real time. Background technique [0002] With the increase of my country's population and the rapid development of economy, the problem of water shortage has become more and more serious, which has affected people's normal life in many areas of our country; and in recent years, with the concept of "sponge city", the effective use of water resources More and more attention has been paid. In addition, with the development of contemporary society, labor costs are becoming more and more expensive, and all fields are bound to embark on the road of automation, energy saving, and intelligence. [0003] After analyzing a large number of experimental reports, it is concluded that most urban green space soi...

Problems solved by technology

When using automatic sprinkler irrigation, most of them do not fully consider the relationship between the above-mentioned soil moisture and soil permeability, but simply and extensively perform irrigation through the logic control of opening and closing, resulting in a large waste of manpower, water resources, and electricity; although a few automatic sprinkler irrigation consider The law between soil moisture and soil permeability, but they only mechanically classify the humidity and the water output of the nozzle, and do not really accurately use and grasp the quantitative function relationship between the soil infiltration rate and soil moisture, and thus are not really accurate. According to the real-time and automatic adjustment of the required sprinkling intensity according to the soil moisture in various places, it is still impossible to truly realize intelligent sprinkling and water saving
