Monitoramento remoto e diagnósticos aplicados a processos industriais, dentro do conceito da indústria 4.0

Abstract

In light of the industry 4.0, remote monitoring and diagnosis applied to industrial processes is critical. In industrial plants where technologies are lagging, this process can be performed using protocols and tools such as MQTT, Modbus and Node-RED. This essay addresses concepts of industry 4.0 applied on remote monitoring and diagnosis, with the aim of create an interface that allows the communication with all field devices which operate with Modbus RTU protocols and the user, remotely. The proposed work aims to create an interface that allows the remote access to field devices in industrial plants already installed and without the available technology. In the context of Industry 4.0, remote monitoring and diagnostics applied to these processes are critical to continuous improvement, decision making, cost reduction, optimization of maintenance, quality improvement and other factors related to efficiency and safety of the production process. To solve the problems related to the lack of technology focused on Industry 4.0, studies were carried out to develop an interface capable of making the connection between outdated field devices, which operate on protocols such as Modbus RTU, and remote access. It was made a study of the main protocol used on the shop floor, which do not have direct access to technologies for remote communication. From these data were researched technologies and devices capable of communicating with this protocol, perform the exchange of data and enable their access remotely. Thus was studied a tool capable of communicating with this interface, based on the TCP/IP standard, to make access and remote control from a computer, from anywhere, connected to the internet network. Thus, a solution was developed that performs the exchange of data between a field device and an online platform through the MQTT protocol, which operates on the TCP/IP architecture. The results show the possibility of adequacy of existing processes for the concept of Industry 4.0. This system allows monitoring the efficiency and performance of operations, which allows it to reduce the response time to unexpected events and failures in the process. This study contributes to the advancement of knowledge in applications related to the adequacy of industrial plants within the concept of Industry 4.0, providing a practical and validated solution for the execution of the mentioned activities, which allows its use in future research in implementations related to updating industrial processes.
