Automação de um sistema industrial com métrica OEE e protocolo MQTT

Abstract

The engineering has a creative ability to propose innovative solutions in terms of processes, products, and services, aiming to achieve better efficiency rates, as well as to propose quality of life and social transformation. In this context, industrial automation has been an agent of transformation in the most recent history of human life. The programmable logic controller (PLC) is the central element in the architecture of automation, mediating information from process sensors and actuators, but also establishing an interface with data management and supervision systems allocated in the cloud. The adoption of automation in an industrial process guarantees some advantages for the company, such as reduction of human error in manufacturing, product uniformity, minimization of cases of repetitive strain injuries, and monitoring of variables of interest by graphics, among others. This work presents a proposal for the industrial automation of a virtual factory, whose process is composed of production, separation, packaging, and product storage stations. The production station is made up of four cells equipped with machining centers with industrial robotic arms. Through the MQTT protocol, it is intended to make production data and production quality index (OEE, Overall Equipment Effectiveness) available on a server. The results from the simulation will show the operation of the virtual factory processes using an OPC connection with the PLC.
