Precision irrigation system using Beidou short message communication function, and precision irrigation method

Abstract

A precision irrigation system using a Beidou short message communication function comprises a central processing module, a mobile monitoring module, and water application modules distributed at nodesin a planting area. The central processing module, the mobile monitoring module and the water application modules are communicated with one another through a Beidou RDSS service with a short message communication function and a positioning function. Each water application module comprises a fixed-type communication terminal, a water application unit and a node sensor group. The node sensor groupscollect node data of the planting area and transmit the node data to the fixed-type communication terminals. The fixed-type communication terminals transmit data to the central processing module through the Beidou RDSS service, receive control signals sent from the central processing module and transmit the control signals to the water application units. By the technical solution, in a vast and remote arid and sandy environment, precision irrigation can be achieved, and the stability of the irrigation system can be maintained. In addition, the invention further provides a corresponding precision irrigation method.

Description

technical field [0001] The invention relates to the technical field of crop irrigation, in particular to a precision irrigation system and an irrigation method using the Beidou short message communication function. Background technique [0002] Agriculture is the foundation of the national economy. my country is a big agricultural country, but also a big water-poor country, especially in the windy, sandy and arid environment, where water resources are even more scarce. Water saving and efficient water use are the extensive demands of crop cultivation. The traditional extensive flood irrigation will cause a huge waste of water resources. [0003] The principle of irrigation is: the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics, growth stage, climate and soil conditions of the planted plants, and timely, appropriate and reasonable irrigation operations should be carried out according to the n...

Problems solved by technology

[0004] In recent years, some irrigation techniques such as sprinkler irrigation, micro-irrigation, and infiltration irrigation have been applied, and have achieved good economic and social benefits, but there are still widespread problems of low irrigation efficiency and water waste. The main reason is that these water-saving irrigation methods Most of the control methods are manual control or timer control, the degree of automation is low, the amount of irrigation depends on experience, lack of scientific management, and water saving is not thorough, which hinders the further promotion of water-saving irrigation

[0005] Some irrigation technologies use wireless communication modules, build the Internet of Things for data transmission, and use the central processor to contro
