Intelligent water-saving fertigation system and method

Abstract

The invention provides an intelligent water-saving fertigation system and method. The intelligent water-saving fertigation system comprises a management control unit, a core processing unit, a soil environment detecting unit, a water detecting unit, a fertilization control unit and an irrigation control unit, wherein the management control unit is used for receiving a remote / local instruction of a manager and forwarding the instruction to the core processing unit; the core processing unit is used for sending a state parameter collecting instruction to the environment detecting unit and the water detecting unit; the soil environment detecting unit is used for obtaining the soil environment information of an irrigation field; the water detecting unit is used for obtaining the water quality information and water pressure information of water used for fertigation; the fertilization control unit is used for controlling the type and the using amount of fertilizer dissolved in water used for irrigation; and the irrigation control unit is used for filtering the water used for fertigation and adjusting the irrigation amount and the water pressure of an irrigation pipeline. The intelligent water-saving fertigation system can achieve the functions of energy and water conservation, remote control, unattended operation, automatic alarming, fertigation instruction, geographical information query and browsing, and the like.

Description

technical field [0001] The invention relates to the field of control technology, in particular to an intelligent water-saving irrigation and fertilization system and method. Background technique [0002] Traditional irrigation schemes do not yet have intelligent self-service functions. Pre-set operations are often implemented through pre-stored irrigation and fertilization strategies. During the irrigation process, only the switch and timing of irrigation equipment can be controlled, that is, only the irrigation time and / or Or the irrigation sequence, it is impossible to independently select the appropriate irrigation and fertilization method according to the environmental characteristics or soil characteristics of different irrigation sites, and it is also impossible to correct the irrigation method in time according to the irrigation site environment, soil changes and various emergencies. In addition, the existing irrigation system still requires real-time monitoring by ma...

Problems solved by technology

[0002] Traditional irrigation schemes do not yet have intelligent self-service functions. Pre-set operations are often implemented through pre-stored irrigation and fertilization strategies. During the irrigation process, only the switch and timing of irrigation equipment can be controlled, that is, only the irrigation time and / or It is impossible to independently select the appropriate irrigation and fertilization method according to the environmental characteristics or soil characteristics of different irrigation sites, and it is also impossible to correct the irrigation method in time according to the environment of the irrigation site, changes in the soil, and various emergencies.

In addition, the existing irrigation system still needs real-time monitoring by managers with professional knowledge, and timely response to equipment failures or abnormal phenomena in the process of irrigation and fertilization, which wastes human resources and affects irrigation efficiency
