Embodiment 1

[0068] Embodiment 1 of the present invention: a kind of Internet of things intelligent irrigation and fertilization control method based on fuzzy control comprises the following steps:

[0069] 1. Data collection

[0070] like figure 1 As shown, after the system is initialized, open the COMO serial port. If the communication test data can be sent and received normally, it will start to load the water demand law and fertilization formula of the crops, and collect soil temperature and humidity, soil nutrients, air temperature and humidity, wind speed, rainfall, flow, pool Data such as water level and pipe network pressure are stored in the database together with the above data.

[0071] 1. Law of water demand

[0072] Research on the law of water demand of major crops such as corn, wheat, flue-cured tobacco, rape, and rice.

[0073] 1.1 Corn irrigation control indicators

[0074] In this experiment, seeds were sown on April 12, seedlings emerged on May 15, and harvested on S...

Embodiment 2

[0258] Embodiment 2 of the present invention: a fuzzy control-based Internet of Things intelligent irrigation and fertilization control system that implements the method described in Embodiment 1, such as figure 2 shown, including:

[0259] Information perception layer 1 is used to complete the perception and collection of information data, and store the information data in the database. The information data includes soil humidity, soil nutrients, air temperature and humidity, wind speed, rainfall, pool water level, flow, The pressure of the pipe network and the working status of the relay control equipment,

[0260] The information application layer 2 is used to read the corresponding data in the database, complete the statistics, analysis and processing of the collected information data, and use the fuzzy control algorithm and the coupling model of water and fertilizer to intelligently control the irrigation valve and fertilization valve; The limit value of the pool water ...

Abstract

The invention discloses a fuzzy-control-based internet of things intelligent irrigation and fertilization control method and system. The method comprises the first step of data collection and processing, wherein limiting values of the soil humidity, nutrients and pond water level and the irrigation and fertilization planning time are set and stored in a database according to the water demand regulation and a fertilization formula of crops, and collected soil temperature and humidity, soil nutrients, air temperature and humidity, air speed, rainfall, flow, pond water level and pipe network pressure data; the second step of intelligent control, wherein corresponding data are read from the database and an irrigation valve and a fertilization valve are intelligently controlled by the adoption of the fuzzy control algorithm and a water and fertilizer coupling mode, by comparing the current pond water level with the set limiting value of the pond water level, starting and stopping of a water pump are intelligently controlled, and the speed of the water pump is adjusted and controlled by a PID algorithm. The fuzzy-control-based internet of things intelligent irrigation and fertilization control method and system have the advantages of being good in performance, complete in function, high in expansibility, easy to operate and manage and the like, and intelligent management and control are achieved by the adoption of fuzzy control.

Description

technical field [0001] The invention relates to a fuzzy control-based Internet of Things intelligent irrigation and fertilization control method and system, belonging to the technical field of agricultural irrigation and fertilization. Background technique [0002] The application prospect of "Internet of Things" in agriculture is broad, but my country is still in its infancy, especially in the aspect of intelligent irrigation and fertilization, which mainly stays in the stage of monitoring and report statistics, without linkage with related control equipment, and has not realized irrigation and water saving. and fertilization saving. [0003] At present, agricultural irrigation has shortcomings such as separation of water and fertilizer, serious waste of water and fertilizer, and aggravation of agricultural non-point source pollution. Patent CN102165876 "intelligent water-saving irrigation and fertilization system and method" has high technical requirements for use, is not ...
