Abstract

The Intelligent Networks Institute (INRI) of the Federal University of Santa Maria has a complex laboratory structure dedicated for electronic equipment testing focused on solar systems. This demands large electrical connections and high power instruments. The equipment and instruments are used for academic research purposes as well as for professional activities, such as commercial equipment certification (INMETRO accreditation). As commercial equipments tested are subject to strict regulations and secrecy, their physical access was limited by means of laboratory aceess control. With the objective of enabling

usage of all available equipment for both purposes an electrical micro-network was conceived and installed. This network is made of cable harnesses and switches capable of selecting which device is connected to which laboratory. It also has hardware interlocking features on its power and communication circuits. This work describes the design of this network, as well as the automation concepts for its electromechanical components.
