Abstract
The article is devoted to the development of an automated control system for irradiation facilities. The system will optimize the electricity cost for supplementary lighting plants in greenhouses without economic losses. A number of scientific researches studying chlorophyll, photosynthesis and processes in the green plant leaf were analyzed as the theoretical base for the present article. On their basis, a schematic structure of the photosynthetic apparatus of plants was developed and kinetic differential equations describing the structure and functioning of the photosynthetic chlorophyll apparatus of green plants were derived. The obtained mathematical expressions describe the changes in the concentrations of the base materials that participate in the formation of the photosynthetic apparatus structure and the accumulation of photosynthesis products and allow effective controlling of the irradiation process of plants. It has been achieved by adjusting the parameters of the illumination interval and the illumination area with the aid changing the number of switched on and off sources of optical radiation and changing the spectral component in a narrow limit.
Highlights
The development of an automated control system of irradiation facilities will optimize the irradiation modes for growing plants in protected soil
This is used to obtain the maximum integral photosynthesis and the creation of an automated control system by irradiation facility based on the results
It is planned to obtain data in real time and control the radiation spectrum with the help of the present installation thereby affect the process of photosynthesis and the development of the plant as a whole
Summary
The development of an automated control system of irradiation facilities will optimize the irradiation modes for growing plants in protected soil. This will help to save energy and increase crop yields. The major task is to find the optimal distribution of radiation energy in time This is used to obtain the maximum integral photosynthesis and the creation of an automated control system by irradiation facility based on the results. Each element of the leaf can interact with radiation energy in one way or another In optical terms it can be characterized like other physical bodies by transmittance and absorption factors in accordance with the laws of optics and photometry. The rate of biochemical reactions taking place in the plant is determined by the occurrence of growing medium, the initial substances concentration, temperature
