Sistema de seleção automática para laboratórios de acesso remoto da área de mecatrônica

Abstract

The use of the Remote Access Laboratories will be applied in the work, specifically in the use of the plants of the discipline MPS (Modular Production System) for the execution of the practical activities of the students of the area of Mechatronics. From this conception an automatic selection system was implemented that registers institutions that wish to share their laboratories with the students who will test their experiments. For institutions to have a RAL (Remote Access Remote) registered in this system is necessary a laboratory with a computer and monitoring camera with broadband internet access, in addition to a programmable logic controller to perform commands in the plant process of the MPS line. With the registration made the student must install the software of his platform that was built to give access to the RALs making a connection through the RDP (Remote Desktop Protocol) protocol to the environment chosen by the system. This selection happens through an algorithm that verifies the characteristics of each laboratory to choose the best environment for the execution of the student activity, when the RAL was chosen it is possible to program the controller of the experiment, simulate or execute its application in the didactic plan, besides visualizing the video of the process in operation. The selection of laboratories of this system happens by verifying the conditions of each environment, if it is active or inactive, occupied or free and if the didactic plan is in agreement with the student experiment, after analyzing these conditions of the laboratory, the quantity of students and the state of internet connection to be able to choose the best space of experiments for the student. This selection process resulted in the creation of an equation of choice to efficiently search the laboratory, optimize the use of laboratories, and generate a parameter called operational cost that weighs more heavily on the decision of the chosen laboratory. Therefore this work can contribute to a better choice considering the main parameters for the efficiency and effectiveness of remote access to RALs, the use of RALs from other institutions, the reduction of the student's waiting time in performing their experiments and forming a network sharing of laboratories in the MPS line.
