DEVELOPMENT OF A CONCEPT FOR THE IMPLEMENTATION OF A MICROPROCESSOR SYSTEM FOR MEASURING THE TEMPERATURE OF GREENHOUSE COMPLEXES

Technological progress is characterized by the continuous expansion of automation across all areas of human activity, transitioning from partial automation to comprehensive automation, and then from comprehensive automation to full automation, which ensures the highest technical and economic efficiency. This work develops a generalized concept for implementing a microprocessor-based temperature monitoring and control system for greenhouse complexes. It is characterized by high adaptability to the size and needs of greenhouse enterprises, as well as high flexibility in applying primary temperature measurement transducers from different types and manufacturers. The mentioned microprocessor system is designed for use as both a subsystem for automated climate control of a greenhouse complex and as a standalone system for monitoring the temperature distribution gradient within the greenhouse. The architecture and a generalized prototype of the software for the temperature monitoring system in greenhouse complexes have been developed. This system can be used in the construction of climate control systems for greenhouse complexes. In each section of the greenhouse, the air temperature is controlled at 6 measurement points, and the soil temperature is monitored at 6 measurement points. The data from the sensors are processed according to several algorithms – for each sensor, for a group of sensors, autonomously by the microprocessor controller (with only alarm messages transmitted to the operator station), or by the operator station, with continuous transmission of real-time data from the microprocessor controller. The system's modular design allows for easy scaling and integration with other greenhouse management technologies, making it suitable for various agricultural applications.
