Abstract

The greenhouse is a closed-type agroecological system in which energy processes are strictly determined by the technological process of growing plants, taking into account the influence of the environment. As you know, greenhouse models are divided into two types: white box models and black box models. The well-known model of the “Soil-Plant-Atmosphere” system belongs to the first type, built on the physical principles of thermo-, hydro- and gas dynamics. They consist of several complex differential equations that use numerous coefficients and parameters that are known in advance. Such models are cumbersome and require large computational resources and time-consuming. The proposed model of the system “Plant-Environment-Situation-Management” is a practical analogue of the well-known model “Soil-Plant-Atmosphere”. The main difference of this model is that it refers to a black box model, which is an approximation of the observed processes and allows you to describe processes based on experimental data. On the basis of the “Plant-Environment-Situation-Management” model, the software and hardware system “Smart Greenhouse” was developed, which is a human-machine system with a rational separation of the functions of preparation (computer) and decision-making (Man). It allows you to control and control the growth and development of the plant during the growing season, taking into account the influence of environmental conditions. The system is implemented and used in the greenhouse of the al-Farabi Kazakh National University.
