Repotenciación del sistema de adquisición de datos de la máquina de torsión del laboratorio de resistencia de materiales de la Facultad de Mecánica.

Abstract

The repowering of the data acquisition system of the Torsion Machine of the Materials Resistance Laboratory of the Faculty of Mechanics, in order to improve its performance, implementing an automatic control system through a programming made in the TIA PORTAL software which involves a set of electrical elements such as electronic: a Simatic S7-1200 PLC, with an SB 1232 expansion module (Signal Board) with an analog output, a compact touch screen HMI KTP 400B BASIC PANEL COLOR 4 " (four inches), an incremental optical encoder, a load cell controller, a power source Logo Siemens, voltage amplifier board, voltage transformer, relays, stop button, signal lights. Obtaining favorable results because, through the screen, it can monitor, control and acquire the torsion test data. The data obtained by the interface was calibrated by measuring with a weight system, which allowed us to perform a torque error analysis, which was corrected with the linearization equation of the expected value with the calculated value. Finally, the database that has been generated from the properties of the material in real time can be downloaded from the PLC.
