MICROCONTROLLER MANAGEMENT OF ENERGY CONSUMPTION IN COMPUTER CLASS

Abstract

The paper presents the results of designing a microcontroller system for controlling the energy consumption of electronic equipment in a computer classroom. It is indicated that due to objective circumstances (rising electricity prices, military operations), energy saving issues are among the most important for educational institutions in Ukraine. However, the level of energy savings in educational institutions is low due to the fact that a significant number of them are not equipped with automated energy management systems and energy monitoring systems. To effectively manage the energy consumption of both a single classroom and an educational institution as a whole, it is advisable to develop a microcontroller control system that can conduct energy monitoring, control the microclimate, and operate as part of a sensor network. The information from the sensor network will be used for the energy management system of the educational institution. It is recommended to create a computer classroom consumption management system on an inexpensive high-speed microcontroller EK-TM4C123G from Texas Instruments. The large number of inputs/outputs of the microcontroller, its high bit depth and speed will ensure the operation of a significant number of sensors and allow it to work effectively in the system of monitoring the energy consumption of an educational institution. The sensors of the control system are cheap sensors with standard signals developed for the ARDUINO platform. Algorithms have been developed for efficient energy management that take into account the operating mode of the computer classroom. Experimental studies of the developed control system were carried out for two weeks, which resulted in a 30.2% saving in electrical power and positive feedback on the quality of the microclimate in the computer room. The optimal configuration of the system and the high computing power of the microcontroller allow us to create a neural network for intelligent control of energy consumption in the educational institution and raise its energy management system to a new level in the future.
