Desarrollo de un Sistema Scada para la Medición de Temperatura con Sistemas Embebidos para el Laboratorio de Mecatrónica de la Facultad de Mecánica.

Abstract

The present research is about the data acquisition and monitoring controlling system development (SCADA) with the application of CompactRIO of NI which has modules to measure the temperature, voltages, currents, digital signals, analogical signals based on the new technology of inputs and outputs (I/O), by using scanning that permits to execute the systems in real time. This research is focused on the application of module NI 9213, a system for temperature measurement which permits to use sensors such as thermocouples type J,K,T,S,B,N,E,R. Module NI 9213 programmed at the LabVIEW processes the temperature for controlling and monitoring. Three practices of temperature measurement were carried out. In the first one, the temperature is controlled and monitored in a furnace in which a thermocouple type K was installed; a fan was also used to freeze the furnace niccolite when these get the desired temperature. The furnace temperature can be varied through a set point. All this process is executed by a Discrete Control (ON/OFF). In the second one, the temperature is monitored in a refrigeration system of the Thermic Lab at Mechanics Faculty in which five thermocouples Type K were installed. In the third one, boiler steam temperature measurement was carried out. These practices include data acquisition and excel report generation.
