Desenvolvimento de um supervisório em sistemas HVAC responsáveis pelo tratamento de ar em estabelecimentos assistenciais de saúde (EAS)

Abstract

HVAC Systems (Heating, Ventilating and Air Conditioning) have numerous instruments to measure and control system variables. The operation of these systems is done from supervisory control and data acquisition systems that are called SCADA or Supervisory systems as they are commonly called. There are numerous softwares on the market that implement this type of supervision. However, they have a high added cost which makes them unfeasible for small systems. With this, this work aims to develop a supervisory in an open-source SCADA platform in order to enable the implementation in small projects. For this, we used a real HVAC system implemented in a hospital, a PLC (Programmable Logic Controller), data communication protocols aimed at industrial automation called BacnetIP and RS-485. This work explores the tools available on the ScadaBR platform, such as real-time monitoring of system variables, alarm generation and graphic screen development.
