Tomato irrigation intelligent control system

Abstract

The invention discloses a tomato irrigation intelligent control system. The system is formed by a tomato growing environment soil moisture collection and control platform and a tomato growing environment soil moisture intelligent control system. Aimed at the characteristics of tomato growing environment soil moisture parameter variation of nonlinearity, large time lag, great inertia, and time dependence, and problems that the tomato growing environment soil moisture parameter variation is hard to accurately detect and control, the tomato growing environment soil moisture intelligent control system based on a wireless sensor network is designed. The system is an intelligent monitoring system which detects, intelligently controls and manages soil moisture of a controlled tomato growing environment through the tomato growing environment soil moisture collection and control platform and the tomato growing environment soil moisture intelligent control system, so as to realize high-quality efficient regulation of tomato growing environment soil moisture, and improve tomato quality and requirements of economic benefits of growers. The system has wide application prospect and great popularization value.

Description

technical field [0001] The invention belongs to the field of intelligent control of soil moisture regulation in tomato growth environment, and in particular relates to an intelligent control system for tomato irrigation, which realizes detection, control and management of soil moisture in tomato growth environment. Background technique [0002] Vegetable production in my country is basically still in the initial stage of pursuit of yield. Farmers rely on a large amount of fertilizer and water to pursue high yield and high efficiency of crops; but this can easily reduce the quality and flavor of vegetables. The root system is the main organ for plants to absorb fertilizer and water, and it is also the organ for the assimilation, transformation and synthesis of various substances. Therefore, the growth of the root and its activity directly affect the growth, nutritional status and yield level of the plant. The growth and development of the root system and its activity are dir...

AI Technical Summary

Problems solved by technology

However, these methods have poor real-time performance and low control precision, and do not take effective control measures according to the needs of soil moisture in each growth stage of tomato and the characteristics of nonlinearity, large lag and large inertia of soil moisture changes. Therefore, improving the tomato growth environment soil The reliability, robustness and accuracy of water regulation are very necessary. Since there is still no high-quality and efficient control of soil moisture in the tomato growing environment in China, this patent is based on this reason to invent a tomato irrigation intelligent control system.
