Illumination intensity monitoring and automatic regulating system for agricultural greenhouse

Abstract

The invention relates to an illumination intensity monitoring and automatic regulating system for an agricultural greenhouse. The system comprises an illumination intensity sensor, an illumination intensity signal processing unit, a wireless sending unit, a wireless reception unit, a microprocessor, a relay, an illumination intensity adjusting device and a PC, wherein the illumination intensity sensor, the illumination intensity signal processing unit and the wireless sending unit are electrically connected successively; the wireless sending unit, the microprocessor and the PC are electrically connected successively; and illumination intensity monitoring software is installed in the PC. The illumination intensity sensor acquires the illumination intensity in an agricultural greenhouse and outputs the illumination intensity to the illumination intensity signal processing unit; the illumination intensity signal processing unit processes the illumination intensity signal, and then the illumination intensity signal is sent wirelessly through the wireless sending unit; the wireless reception unit receives the illumination intensity signal, and then the illumination intensity signal is processed through the microprocessor and is output to the PC; and the PC realizes real-time monitoring of the illumination intensity of the agricultural greenhouse. The illumination intensity monitoring and automatic regulating system for an agricultural greenhouse is high in real-time and efficiency, and has no requirement for performing complicated wiring.

Description

technical field [0001] The invention relates to the field of light intensity monitoring of agricultural greenhouses, and more specifically, to a light intensity monitoring and automatic adjustment system of agricultural greenhouses. Background technique [0002] Light intensity is an important parameter that determines plant photosynthesis. Although there is no fixed proportional relationship between light intensity and plant photosynthesis, within a certain range of light intensity and other conditions are met, with the increase of light intensity, the rate of photosynthesis will increase. The intensity also increases accordingly. But when the light intensity exceeds the saturation point of light, the light intensity increases again, and the photosynthesis intensity does not increase. When the light intensity is too strong, it will destroy the protoplasm, cause the decomposition of chlorophyll, or cause the cells to lose too much water and close the stomata, resulting in w...

AI Technical Summary

Problems solved by technology

This method has poor real-time monitoring of light intensity, requires a lot of energy from agricultural production personnel, and has extremely low production efficiency. Once agricultural production personnel are negligent, it is easy to affect the normal growth of plants in agricultural greenhouses due to excessive or low light intensity.
