Electrobomba DC modificada como actuador inteligente

Abstract

Introduction: The article is the product of the research "DEVELOPMENT OF AN ACTUATOR FOR HYDRAULIC SYSTEMS", developed during 2014 in the technological faculty of the Francisco José de Caldas District University. Objective: After recognizing and modeling different types of DC pumps, it is necessary to identify the circuits that allow controlling an electric pump with a simple signal through an intelligent system. Methodology: The resulting intelligent actuator device guarantees a standard operation to be developed in compliance with the IEEE 1451 family-standard, this defines a set of communication interfaces that characterize intelligent transducers connected to systems based on microprocessors, instruments and networks; the architecture defines: a Network Capable Application Processor (NCAP) and a Transducer Interface Module (TIM), in addition an interface between both through the IEEE 1451.X communication module. The integration is done in a low-cost pre-configuration platform -like the acquisition cards- that displays, records and manipulates information from an actuator through a personal computer. Results: a low cost system was obtained based on the Raspberry Pi processor -as an intelligent core of the system- where it is integrated: a PSOC 4 microcontroller to interact with the signals of the actuator, a circuit to manage the energy between the pump and the microcontroller, and an integrated signal that goes to the central processor. To the above, an NI-USB data acquisition card is added to interact analogously with the computer. Conclusions: The intelligent actuator system makes it possible to control the flow of an electric pump actuator for a multi-tank teaching plant, this intelligent actuator complies with the family of IEEE 1451 standards, where the user can control the variables indicated in a digital or analogous way. Originality: In Colombia these low cost intelligent systems are not available for teaching plants like the one developed. Limitations: in non-didactic plants it is necessary to extend the research to the industrial sector and increase the budget of the elements.
