Implementación de un sistema de adquisición de datos de sonido, corriente y temperatura mediante IOT para máquinas rotativas

Abstract

The purpose of this Curricular Integration Work was the construction of a data acquisition module composed of six sensors of sound, current, and temperature; these will take actual values from the BPR-6206 module, and these values were uploaded and interconnected with the Cayenne myDevices platform to download, graph and organize them in Excel format finally. The sensors that make up the data acquisition module are sound sensors capable of measuring the sound emitted by bearing number one; the sound of this bearing was isolated, thanks to the construction of a wooden box as the base of said sensor. The sound of a new bearing was also compared to have a reference value for this module to emit alert signals if it exceeds the said value. This wooden base was used to place a new sensor to take temperature data from the same bearing. This task was achieved by configuring the sensor according to body temperature. Considering it is a three-phase motor, three current sensors were located, one for each phase. Finally, the data acquisition module consists of an ambient temperature sensor. The results were analyzed by developing programming in MATLAB. This program is intended to filter and order the values obtained according to the date and time, facilitating the understanding and reading of data. These values were graphed to improve the visualization of the results. In conclusion, it can be said that the ESP-8266 Wifi device was vital since it allowed the values to be uploaded to the Internet and interconnected with other types of sensors. Keeping the Cayenne myDevices platform active is always recommended since it will stop taking values if put to sleep , and all sensors must be restarted.
