Abstract

The invention is applicable to the technical field of farmland irrigation, and provides an irrigation control method and device. The method includes the following steps that weather information, collected by a meteorological station module, of a to-be-irrigated region and initial soil moisture information, collected by a soil moisture acquisition module, of the to-be-irrigated region are obtained;the growth state of planting crops in the to-be-irrigated region and the running state of an irrigation device in the to-be-irrigated region are obtained; according to the weather information, the initial soil moisture information and the growth state of the planting crops, an irrigation plan of the to-be-irrigated region is determined; according to the irrigation plan and the running state of the irrigation device, an irrigation command is sent to a control unit, and the irrigation command is used for instructing a control unit to control the irrigation device to carry out the irrigation plan. After adopting the above scheme, the irrigation condition of a farmland can be determined, and the soil moisture is maintained in the optimal range of crop growth.

Description

technical field [0001] The invention belongs to the technical field of farmland irrigation, and in particular relates to an irrigation control method and device. Background technique [0002] Soil is composed of minerals, animals and plants formed by weathering of rocks, organic matter produced by the decomposition of microbial residues, soil organisms, water, air, and oxidized humus, which can provide a growth basis for planting crops. [0003] However, since the soil is an inertial and nonlinear system, and the soil environment is changeable, it is difficult to establish an accurate, stable and invariable mathematical model, and the various environmental factors in the farmland are coupled with each other. The key characteristic values ​​of the soil are extracted using the neural network, and the experimental The data establishes the prediction model of the irrigation system to complete the calculation, identification, decision-making and irrigation control tasks. It has a...
