Abstract(s)
Este projeto tem como objetivo fazer o estudo, desenvolvimento e demonstraĆ§Ć£o de
um sistema de monitorizaĆ§Ć£o e controlo de carga centralizado utilizando o conceito
Internet of Things (IoT).
Para servir de exemplo a este projeto foram estudados vƔrios produtos onde
implementam o conceito IoT e/ou a tecnologia de monitorizaĆ§Ć£o de consumo de
energia, como por exemplo a FIBARO, Eyedro, Lumin, Leviton e Trotec. Este
estudo permitiu idealizar e conceber um sistema preparado para monitorizar os
dados de energia elƩtrica e controlo de cargas e exibir esses dados numa interface
grƔfica.
O sistema de monitorizaĆ§Ć£o tem como objetivo realizar a mediĆ§Ć£o da tensĆ£o eficaz, corrente eficaz, potĆŖncia instantĆ¢nea, fator de potĆŖncia, energia instantĆ¢nea e
acumulada, sendo tambĆ©m possĆvel verificar o custo monetĆ”rio associado Ć energia
utilizada. O sistema de monitorizaĆ§Ć£o envolve o estudo e implementaĆ§Ć£o sobre a alimentaĆ§Ć£o do sistema, condicionamento de sinal, analog-to-digital converter (ADC)
externo, placa de desenvolvimento ESP32 DevKitC V4 e o display Organic LightEmitting Diode (OLED). O sistema de controlo por sua vez tem como objetivo acionar um light-emitting diode (LED) e Ʃ realizado atravƩs da placa de desenvolvimento
Mini WEMO D1 ESP32.
Para aceder Ć informaĆ§Ć£o dos dados de energia elĆ©trica e realizar o controlo do
LED foi desenvolvida uma pƔgina de Internet baseada na plataforma Node-RED.
Para desenvolver a plataforma utilizou-se um servidor que irĆ” correr a plataforma
Node-RED e disponibilizar o endereƧo Internet Protocol (IP) da pĆ”gina de monitorizaĆ§Ć£o e controlo. Os dados transmitidos entre os microcontroladores e servidor utilizam o protocolo de comunicaĆ§Ć£o Message Queuing Telemetry Transport (MQTT).
Por fim, foram realizados testes ao sistema tendo como base de comparaĆ§Ć£o os
dados de energia resultantes do dispositivo de mediĆ§Ć£o de energia Aubess. Os resultados obtidos do dispositivo Aubess e do nosso sistema sĆ£o idĆŖnticos, concluindo
assim que o sistema de monitorizaĆ§Ć£o desenvolvido funciona de acordo com o es perado. A implementaĆ§Ć£o da placa de desenvolvimento Mini WEMO D1 ESP32
tambĆ©m demonstrou estar corretamente implementada na rede local sendo possĆvel alterar o estado do LED entre ligado e desligado.
This project aims to study, develop and demonstrate a centralized load monitoring and control system using the IoT concept. To use as an example several products were studied where they implement the IoT concept and/or energy consumption monitoring technology such as FIBARO, Eyedro, Lumin, Leviton and Trotec. This study allowed to idealize and design a system prepared to monitor the data of electric energy and load control and display these data in a graphical interface. The monitoring system aims to measure the power factor, intantaneous and accumulated energy, instantaneous power, Root Mean Square (RMS) voltage and RMS current, also being possible to check the cost associated to the energy used. The monitoring system embraces the study and implementation of the system power, signal conditioning, external ADC, ESP32 DevKitC V4 development board and the OLED display. The control system, in turn, aims to activate a LED and it is carried out through the Mini WEMO D1 ESP32 development board. To access the electrical energy data information and carry out the LED control an Internet page based on the Node-RED plataform was developed. To develope the platform a server was used that will run the Node-RED plataform and provide the IP address of the monitoring and control page. The data transmited between microcontrollers and server uses the MQTT communication protocol. Finally, system tests were carried out based on the energy data resulting from the Aubess energy measurement device. The results obtained from the Aubess device and from our developed device are identical, thereby concluding that the system works as expected. The implementation of the Mini WEMOD1 ESP32 development kit also proved to be correctly implemented in the local network, being possivel to change the state of the LED between on and off.
