Automated Control Systems in Greenhouses

Abstract

Objective. The purpose of the research is to develop an innovative automated program associated with a completely new irrigation regime based on a closed water supply system.Method. Methods of modeling, formalized description, optimal design and control of technological processes and production were used.Result. An automated control system in greenhouse farming based on Arduino controllers and ONI PLR Studio software for its operation are presented. The scientific novelty of the work lies in the creation of appropriate modes of the climate control system in greenhouses. The ONI PLR Studio program is written in FBD language. It solves important problems of controlling the cultivation of agricultural products, breeding new plant varieties, and controlling the technological process using certain signals. User input is limited to software adjustments and direct setting of controller parameters. The adjustment can be carried out remotely through a computer connected to the controller. The automatic operating mode is provided by sensors and a controller with electronic control circuits, which ensure that the actuators operate in the required mode.Conclusion. An automated control system (ACS) allows you to control air and soil temperature, soil and air humidity, soil nutrition, disinfection, air pressure, lighting, the presence of carbon dioxide in the greenhouse, and climate control.
