Instrumento virtual para adquisición de datos, análisis y evaluación de sistemas dinámicos

Abstract

In this work, a program for signal acquisition and monitoring was carried out, with the purpose of evaluating the behavior of rotating systems. The monitoring program was carried out in the LabVIEW software, in which the behavior of the system is visualized and the different post-processes of the acquired signals are carried out. LabVIEW was chosen because it allows manipulating the obtained data to be used in various post-processes in different programs, which is one of the main advantages that they have over other systems, such as ADRE of Bently Nevada DAIU 208-P, which also , does not allow access to data. The operation of the designed program, its advantages and the secondary programs used for the different post-processes are explained in detail. The experimental platform where the tests were carried out is shown, showing the validations and the correct operation of the program designed in LabVIEW, compared to the monitoring system mentioned above ADRE. Finally, various possibilities are offered to expand the capabilities of this program, these options range from increasing the types of filters used for signals, as well as extracting non-linear characteristics, such as the Largest Lyapunov Exponent (LLE).
