Wireless water-saving drip irrigation automatic control system

Abstract

The invention discloses a wireless water-saving drip irrigation automatic control system comprising a head center, a pipeline module, a drip irrigation module, a control module and a wireless transmission module. The head center is used in water pumping, fertilization and filtration. With the head center, water is delivered into the pipeline module with a preset pressure. The drip irrigation module comprises a plurality of uniformly distributed drip irrigation units. The pipeline module is used for delivering pressurized water to all the drip irrigation units. The wireless transmission module is composed of a plurality of distributed node units and an aggregate node unit. The aggregate node unit is connected with the control module. The distributed node units are connected with the drip irrigation units one to one. The drip irrigation units are used for sensing humidity information and transmitting the humidity information to the control module, and work under the commands of the control module. The control module is used for transmitting corresponding commands to the corresponding drip irrigation units according to the received humidity information. The system provided by the invention has the advantages of simple structure, convenient application and convenient maintenance. With the system, water can be effectively saved.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a wireless water-saving drip irrigation automatic control system. Background technique [0002] With the growth of population, the development of agriculture, and the increasingly severe drought caused by global warming, the demand for water resources in the world is increasing. The shortage of water resources has become a common concern of people all over the world. [0003] Drip irrigation is by far one of the most water-saving irrigation techniques for farmland irrigation. But because of its high price, it was once called "expensive technology" and was only used in high value-added cash crops. In recent years, with the widespread application of drip irrigation belts, "expensive technology" is no longer expensive and can be applied to common field crops. Here is a brief introduction to the layout and construction of greenhouse drip irrigation, fruit tree drip irrigation...

Problems solved by technology

[0012] Existing drip irrigation systems generally can only spray at a fixed time point for a fixed time, and cannot deeply match the humidity of the soil. There are often phenomena of excessive spraying or insufficient irrigation, such as the following patents:
