Diseño e implementación de un sistema de control automático para seis hornos del Laboratorio de Tratamientos Térmicos de la Escuela Politécnica Nacional

Abstract

This project was carried out with the purpose of design an automatic control system for several furnaces of the heat treatment laboratory of the National Polytechnic School. The system is composed of six high temperature furnaces which have individual temperature probes. Four of the furnaces are electric and the others are diesel and lpg (Liquefied petroleum gas) burner furnaces. The system configuration consists of a PLC Siemens and two thermocouples modules programmed with Tia Portal V12. The interface was developed with WinCC. The user window is composed of several tans where are controls and specifications related to the resources and the control system of every furnace. In order to validate the results obtained, several tests were carried out to check the functionality of the system. According to the results, the system is working properly under the parameters of design considered.
