Sistema para aquisição de dados de máquinas termoformadoras utilizando o protocolo SNMP

Abstract

The technology has always been one of the pillars of productivity advances in the industrial sphere. Nowadays the advent of Industry 4.0 and IoT provides solutions to increase analysis and productivity at the factory level. Data collection in machines and the integration among systems meet these new developments that are vastlygrowing. In this context, this research presents the development of a system for data acquisition from thermoforming machines using the SNMP protocol. It provides a study on protocols that can be used in the IoT scope and demonstrates the communication through the protocol that was applied in the project. The research also provides an overview of the thermoforming process, in order to demonstrate how the signs impact its production performance. Based on the bibliographic research, a microcontrolled data acquisition system was developed and implemented, in order to carry out the acquisition of parameters such as voltage, current and temperature. To measure the project, validation tests were performed on the signals and the R² curve was removed from them, in order to provide the best possible reading. The information collected in the module is treated and sent via Wi-Fi communication to a server which acts as a manager. The system performs the final treatments on the received signals and later it stores them in a database for temporal queries. An information viewer software is also integrated, which allows to graphically analyze real time or past information through the stored data. The access to information is possible through the access available on the company's network, providing visualization and monitoring of the asset. Finally, the installation of the system in the thermoforming machine in a factory environment is demonstrated and adjustments in the network are made to target the readings through the module. Through the collected data, consumption analyzes on the different molds and consumption analyzes with the stand-by system are demonstrated. [resumo fornecido pelo autor]
