Combined planting system control method and device

Abstract

The embodiment of the invention provides a combined planting system control method and device. The method comprises the following steps: receiving real-time measured values of a plurality of parameters which are respectively acquired and transmitted by a plurality of real-time acquisition units; receiving control information transmitted by control equipment, wherein the control information carries regions to be controlled and an irrigation strategy corresponding to the regions to be controlled, and the irrigation strategy comprises a plurality of time periods and set values of a plurality of irrigation condition parameters corresponding to the various time periods; and carrying out control treatment on the irrigation rig of the planting system according to the real-time measured values, the regions to be controlled and the irrigation strategy, and carrying out feedback control treatment on the irrigation rig of the planting system according to the real-time measured value. The device is used for performing the method. The method and device provided by the invention can quickly implement the change adjustment and accurate control on the EC value and pH value of the irrigation liquid, and enhance the automatic control flexibility of the planting system.

Description

technical field [0001] The embodiments of the present invention relate to the field of agricultural technology, in particular to a control method and device for a combined planting system. Background technique [0002] With the rapid development of science and technology, it has brought earth-shaking changes to my country's agricultural field and promoted the birth of modern agriculture. People's requirements for the degree of automation of crop planting system control are also getting higher and higher. Based on the automation of crop planting systems The study of control has also been paid more and more attention by people. [0003] In the prior art, the degree of automation and visualization of the crop planting system is very low, only some individual components (such as valves, switches, etc.) can be controlled through the existing control circuit, the automation control flexibility is poor, and the dependence on workers It is extremely large and causes a certain waste ...

Problems solved by technology

[0003] In the prior art, the degree of automation and visualization of the crop planting system is very low, only some individual components (such as valves, switches, etc.) can be controlled through the existing control circuit, the automation control flexibility is poor, and the dependence on workers It is extremely large and causes a certain waste of resources. For example, the utilization rate of water in agricultural irrigation systems is very low, which not only fails to achieve the effect of precision irrigation but also wastes a lot of water resources, and cannot realize automatic irrigation, which increases the labor force. The amount of labor also affects the harvest of crops; the existing irrigation and fertilization control is inefficient and lagging. After the adjustment of irrigation requirements and strategies, the working fluid in the pipeline cannot quickly reach the target value, and precise fertilization cannot be realized. ; In particular, the current irrigation system advocates energy conservation, intensive environmental protection, and the irrigation system needs to recycle the backwater, and the EC value (used to measure the concentration of soluble salt in the solution and also used to measure the concentration of the liquid) when the backwater is used Soluble ion concentration in fertilizer or planting medium) and PH value content also affect the accuracy of control
