Diseño e Implemntación de un Sistema SCADA para Controlar el Deshidratador de Bandejas a Gas de la Facultad de Ciencias.

Abstract

It has been made the design and implementation of the system SCADA to control the gas deshidrator trays of the Faculty of Sciences of the Polytechnic School of Chimborazo. With the helpof Programmable Logic Controller (PLC) control system is made, which Works on the basis of the information received by the temperature sensors PT100, activating or deactivating the electron valve of GLP, or turns the fan to circulate the air inside the deshydration room in order to achieve a stable temperatura for deshydrate. The humidity sensor helps us to have a display of humidity inside the deshydration room. Through the Touch screen TH765 is carrie out monitoring income and variable temperatura, humidity time which are involved in the process. The comparison of the machine is done before and after implementation of the system SCADA, determining an error in the temperatura stabilization of ±3.5, after automation an error was verified ±1.5, resulting efficiecy temperatura stabilization of 97.28%. the system implementation SCADA successfully stabilized the temperatura also it minimized the time of deshydration, lowering overall time spent by the user, ensuring the product quality deshydrated to make correct temperature stabilization. It is recommenden to dehe students of Industrial processes Lab review procedure manual prior to usin the machine.
