Diseño de un sistema de monitoreo de parámetros de la energía eléctrica, mediante dispositivos inteligentes aplicado a las IoT en uso residencial.

Abstract

The research was focused on designing and implementing a system that allows the energy consumption measurements and monitoring of the existing circuits located on the main distribution board in residence located in Riobamba city in Chimborazo province. The system implementation began from the signals conditioning and was configured through two stages: circuitry and another by programming. The data processing was carried out on the Arduino board, and the processed reading was sent to the Raspberry pi3 board, where the web interface was designed. Good readings of loads less than 5 Amps were acquired from the system with a relative error of 0.06%. An error of 4.06% for loads over 30 Amps was also acquired from the system. also, a forecast of 90.77% was determined in the amperage variation between the six existing loads in residence, as well as the domestic environment network with IoT methodology. This methodology allowed the energy parameters supervision and verification; simultaneously, the data acquired by the measurement modules were stored. In turn, a web interface was transmitted in real-time, and it was notified by SMS (Short Message Service) each time that an unusual consumption occurred. It is concluded that the system works efficiently because the correctly measured data reaches the database and represents 94.69% of the information. Simultaneously, the conventional meter does not provide accurate information on daily consumption or energy quality; besides, the user cannot have a proper record to claim in case of overcharging. It is recommended to amplify the supervision options that allow a power outage in overcurrents that may cause the overheating on equipment.
