Abstract

Abstract: Green plants can effectively purify the air, release negative ions, and form a green field of vision to promote human physical and mental health. Nowadays, with the acceleration of the pace of life and the increase in the pressure of life, people do not have enough time and energy to take care of plants grown indoors in homes. Plants in large office places need to hire professionals to plant them. Raw intelligent control of flower pots can reduce energy consumption, save resources, and realize a smart life of health, environmental protection and low-carbon energy saving. At present, the effective combination of smart flowerpots and the Internet of Things makes smart flowerpots more distinctive and more obvious than traditional flowerpots. The purpose of this article is to study the efficient and intelligent regulation of nutrients in protected soil-less cultivation. In terms of methods, this paper first proposes fuzzy control and fuzzy self-tuning PID control. When the PID parameters of temperature and humidity are controlled by this control system, fuzzy rules, fuzzy reasoning and non-fuzzy processes are also used. In the soil-less cultivation control system, when the humidity in the greenhouse is too low for plant growth, you can choose to adjust the humidity in the greenhouse by starting the spray device or natural ventilation. As for the nutrient liquid level sensor, a light-weight, convenient, simple-to-use, and highly cost-effective water level recognition sensor is manufactured using the characteristics of liquid conductivity. In terms of experiments, between traditional soil-grown lettuce and container-less cabin-grown lettuce under the intelligent control system of soil-less cultivation yields comparative data and results. It is found that intelligent soilless cultivation is superior to traditional soil cultivation in terms planting effects, which reflects the effectiveness of the intelligent soil-less cultivation proposed in this paper.
