Item Automatização de uma máquina industrial para solda de baterias de chumbo-ácido(2022-10-04) Freire, Robson Luiz da Silva; Cervantes, Ania Lussón; http://lattes.cnpq.br/5793691069517813; http://lattes.cnpq.br/6593216871039422Nowadays several applications, as server's centrals for data analysis, requires an electrical power source capable of supplying large amounts of charge uninterruptedly. For these applications, lead acid batteries are the most viable option and, therefore, the most used in this kind of scenario. In order to fulfill this demand, the lead acid battery manufacture continues to be in increasing requisition, which in turns requires the construction and development of machines that allow the fabrication of this type of battery. This monograph addresses the automation and control project of a machine with the goal of assisting in one of the lead acid battery productive process phases. The machine in question is unique and was developed specifically for addressing the necessities of the client company which is a lead acid battery fabricant. Because of this, understanding the machine requires a presentation of all their constituents’ parts, the elements used in their electrical project and the tools used to structure the used control logic. In this way, this monograph presents the didactic way in which the project of a battery cell welding machine is developed, presenting its control logic and a humanmachine interface for its operation. In the end, it is concluded that the performance achieved by the designed machine was satisfactory for the requirements of the client company.Item Sistema de supervisão e controle da planta piloto do LIAC(2020-11-04) Silva, Natasha Milena do Santos da; Cervantes, Ania Lussón; Gomes, Flávio da Silva Vitorino; http://lattes.cnpq.br/3701230748191590; http://lattes.cnpq.br/5793691069517813Industrial automation is an area that stands out more and more for the benefits it brings to the production process, they are: improving quality and productivity and reducing costs. Therefore, it is extremely important that engineering graduates put their knowledge on the subject into practice, and didactic plants are great tools for this purpose. This article presents a supervision and automatic control system of the pilot plant present in the Laboratory of Instrumentation, Automation and Control (LIAC) at UACSA-UFRPE, aiming to cover the first three levels of the automation pyramid: field devices, control and supervision. The system architecture consists of two reservoirs, a programmable logic controller S7-1200, sensors, actuators, and the Elipse SCADA and Matlab software. The methodology for modeling using experimental identification for the level system is presented applying an input step to the plant, with the data being accessed from the supervisory system by the network through the OPC protocol. With the model obtained, simulation and experimentation results are presented using the Proportional-Integral (PI) control strategy for changes in the reference. Finally, a plant supervision and control system and a human-user interface are developed, allowing supervision of the four process variables: level, temperature, pressure and flow, and the level control in the upper reservoir. In addition, it is possible to manage alarms, historical records and reports, for decision making in failure prevision, maintenance and troubleshooting.
