Desarrollo de un sistema de control en tiempo real para medir las variables de presión y velocidad con sistemas embebidos.

Abstract

The design and implementation of a system training module for the control of pressure and velocity variables with embedded systems was carried out. For the development of this work the investigated of communication was applied, as well as topology, and configuration of programming language to achieve the sending and receiving data obtained from the sensors in this case of the pressure transducer and the quadrature encoder. The control system consists of three sensor aspects, embedded hardware and embedded software. For the latter two, a Ny myRIO card was used for data acquisition and LabVIEW software. Once the communication has been created, the PC and each one of the electronic devices make up the module come into play. One device is programmed at the same time in FPGA language; this language is exclusive for embedded systems. The system is designed for the control, monitoring and acquisition real time data. This was implemented in the Control and Automatic Manipulation Laboratory of the School of Maintenance Engineering. Performance tests were carried out to verify the acquisition of data for each of the variables, the pressure translator was subjected to different pressure ranges until the activation of the configured safety alarm was confirmed, the frequency of the pulse train was varied to obtain different speeds to know the state of position and the direction of rotation of the engine. Prior to the manipulation of the module, a correct familiarization of the use of all the elements that have been used in the development of this work is recommended.
