Diseño e implementación de un sistema de adquisición de datos, mediante IoT utilizando un microcontrolador para el monitoreo de máquinas rotativas

Abstract

The objective of this technical project was to design and implement a data acquisition system through IoT, using a microcontroller for monitoring rotating machines. In which the BPR-6206 bearing test module was achieved. Constant monitoring was carried out using three types of sensors, such as: temperature, the MLX90614 infrared sensor, speed, the E6B2-CWZ3E incremental encoder and vibration, the MPU 9250 accelerometer, was programmed in Arduino IDE, and configured in the ESP-32 microcontroller. Joining these electronic elements, we obtained the MAE devices, when pressing their send button. They captured physical signals, conditioned and send the information (data) to the cloud with the help of IoT Cayenne myDevices platform. The data was displayed in real time within the platform. They were downloaded, but due to their rough way of download, they were processed by the MATLAB program. They were normalized, and are downloadable, allowing a data record to be kept in excel format. For data acquisition, the operator had to be present with the laboratory instruments, but with the MAE devices, the result is that the operator. After turning on the devices and pressing the sent button, does not have to be present in the time to acquire and send data. It is concluded that, for its implementation and fixed coupling, they will have neodymium magnets in their bases. The batteries have a duration of 4 to 5 hours, and in order to prolong their useful life, the operation manual and maintenance were prepared for the data acquisition system. It is recommended to calibrate the sensors, according to the environment in which they will be used.
