SUBSYSTEM FOR SITUATION RECOGNITION AND DECISION SUPPORT REGARDING LIGHTING, MICROCLIMATE AND MULTIMEDIA IN THE CYBER-PHYSICAL SYSTEM "SMART HOME"

Abstract

Considering the selected components (TSL2561, BME280, Max9814 sensors and ESP32 controller), as well as the I2C, Wi-Fi and MQTT data queuing standards, the architecture of the subsystem for recognizing situations and supporting decision-making regarding lighting, microclimate and multimedia in the cyber-physical system "Smart Home" has been designed. The developed subsystem for recognizing situations and supporting decision-making is an integrated technological core of the cyber-physical system "Smart Home" and provides three key comfort functions - controlling lighting, microclimate (temperature and humidity) and multimedia volume, and does so in a comprehensive and coordinated manner. It guarantees the automatic creation and maintenance of an optimal living environment through continuous monitoring, analysis and interconnected adjustment of all parameters based on a single rule base. This subsystem can be used for automatic energy saving (e.g., turning off the lights, lowering the heating, turning on the humidifier, etc.), for creating adaptive comfort scenarios (e.g., automatically adding light, increasing the temperature in the evening, or turning on the humidifier when the air is dry), for operational control of safety and quality of life (e.g., notifying about a sharp temperature jump or exceeding a critical noise level), as well as for optimizing the operation of multimedia systems (e.g., automatically reducing the multimedia volume at night). The scientific novelty of the research lies in the development of an integrated architecture of the situation recognition and decision support subsystem of the cyber-physical system "Smart Home", which, unlike known solutions that focus on only one group of functions (for example, only microclimate), provides comprehensive and coordinated control of three key groups of housing functions (lighting, microclimate, and multimedia), which guarantees the automatic creation of a comfortable environment through simultaneous analysis and interconnected adjustment of all parameters based on a single rule base.
