Automatización del banco de pruebas para medición de flujo y control mediante un sistema SCADA en el laboratorio de control industrial de la Facultad de Mecánica

Abstract

The present work detail the automation of the control and flow test bench through a SCADA system with a PID control algorithm for the Industrial Control laboratory of Mechanics Faculty to control variables flow, pressure and temperature, which has the ability to present readings through the computer. Through a SCADA system can obtain and control data of variables from the measurement of flow of a process, this is archived through the different instruments installed in the system that transmit signals to a data acquisition card to be able to interface with the computer through LabVIEW. The signals were conditioned according to the characteristics of the data acquisition card, were normalized to current in a value of 4 to 20mA and in voltage of 0-5 V DC. The disturbances in the system are made by a frequency converter and the flow control by means of a proportional pneumatic valve. In the user interface it can be seen that the process variable measurement units coincide with the registers of the indicators installed in the module. The test of the module allow the user to supervise and control the evolution of the process, which is a recommended to follow the guidelines for the student.
