Desenvolvimento de um sistema de monitoramento industrial baseado em IoT para reguladores de tensão

In this article, a monitoring and control solution through the Internet of Things (IoT) will be presented, based on LPWA networks for medium voltage regulators, integrating this equipment to the concept of intelligent networks (SG). In this sense, a complete development of the project will be presented, encompassing the study of the DNP3 communication protocol, responsible for exchanging information with the regulatory relay, the hardware systems using microcontrolled devices, responsible for making the interface between controller relay and communication networks with the cloud (SigFox and GPRS network), in addition to dedicated supervision software developed for the needs of cooperative partners in the project. To achieve the objective of monitoring the data, bench tests were developed to validate the hardware and software during expressive periods, and finally the installation was carried out in the field, validating the experiment in the collection of information by reading and recording the read parameters, such as voltages and currents, numbers of operations and alarm situations that may occur.
