Implementación de un sistema de control y supervisión multiplataforma industrial para la caldera de proceso de pasteurización didáctica del laboratorio de control y automatización de la Universidad Distrital Francisco José de Caldas, Facultad Tecnológica

Abstract

Industrial automation is based on the control and supervision of variables that occur in a repetitive process, which achieves superior performance and manual operation, administration and control of this refers to the different platforms of industrial programming as RsLogix5000, CODESYS V3.5, TIA Portal, among others; As a result of this, the students of engineering and control of the Francisco José de Caldas District University, Technological Faculty, have built as part of their academic and professional training in a scale of industrial processes, this is the case of the modular didactic pasteurization plant , the RsLogix5000 for the control and monitoring of variables such as temperature, level, pressure, pH among others; one of the modules that integrates the boiler, is responsible for generating steam at 40 PSI-140 ° C, in this project is made the conditioning of sensors and actuator equipment: pump, resistance and manual valve type needle that allows the output of steam, for which conversion mechanisms were implemented for the proportional opening conversion, also included in the control panel a restructuring to integrate the SoftPLC V1.0 and the HMI (Human Machine Interface) screen, finally see The reservoir of water to one of greater capacity and robustness. A new SoftPLC V1.0 controller was integrated with the CODESYS V3.5 programming platform, taking into account that the boiler already has an Allen Bradley controller from Rockwell Automation and its programming platform is RsLogix5000, these two controllers are converted into a system multiplatform that control the operation of the boiler independently. The SOFTPLC V1.0 emulates the functions of a PLC with I / O and analog and digital with the help of the program CODESYS V3.5 SP14. This platform obtains the data of the analog and digital signals through a PSoC 5LP microcontroller for the SPI protocol medium (serial peripheral interface). With regard to the design of the controller, Toolbox of the MATLAB software is used for the system identification process, complemented by experimental methods (process identification). The controls became a "pseudocode" to be implemented in the SoftPLC V1.0. A 7 "HMI screen complements the process of monitoring and supervising the operation of the boiler. It is expected that this project will benefit the students of the District University through the development of laboratory practices and the implementation of the control and supervision of the boiler with the programming platforms and the activities of the start-up in the process.
