Evaluación de los Esquemas de Automatización Industrial de Lógica Cableada y Lógica Programada.

Abstract

The industrial automation circuits of wired and automatic logic were evaluated in the Electrical Machines Laboratory of Electronics Engineering in Control and Industrial Network School, Faculty of Electronics y Computer Science at Escuela Superior Politécnica de Chimborazo. The purpose of this research is to evaluate the available technology in order to carry out maneuvers in the industry, as well as to study the conditions under which the devices work considering the wired automatisms technology and programmed technology. The research started collecting data by surveys to technical staff from different companies and industries at the national level, after that, we processed data for testing our hypothesis and choice of circuits. Didactic training modules for industrial automation were developed by wired logic based on electromechanical devices as well as programmed logic with programmable logic controllers (PLC). The modules consist of a steel structure with aluminum which serve as a support for electrical devices, elemecanique programmable logic controller (PLC) with software Zelio was equipped to automate some industrial applications. In addition, they have four expansion chambers contactors, 4 auxiliary contacts which serve to implement the wired technique; we used for signaling processes 4 LED lamps red, yellow, green and blue, we use mushroom, Stop pushbuttons, 3 rotary push buttons, two start buttons and 2 stop buttons, two-phase circuit breakers as control elements to circuits. When we tested on the modules, we compare differences between the techniques described above and the proper handling of the devices. Using Chi-Square method, we found the value of the alternative hypothesis corresponding to 120.79as well as he value of the null hypothesis 90.53. There before the null hypothesis was rejected and the alternative hypothesis was accepted. We conclude similar importance of evaluated techniques in the research according to the environment in which they will play. It is recommended that Teachers of Engineering in Control and Industrial Network School use this research as well as the reflected practical application in the modules to their students in order to create a better development in the industrial sector.
