Diseño e implementación de un prototipo de control y monitoreo de procesos con sistemas embebidos Arduino y Raspberry Pi para PYMES.

Abstract

This research focuses on the design and implementation of a control and monitoring system based on the embedded systems of the "open source", Arduino and Raspberry for a prototype process of dosage for solid, capping and sealing in metal jars of 125 cc. This prototype has been taken as pilot model to present a technification option for the processes of small and medium enterprises (SMEs). Solid Works was used for the structural design of the process, determination of maximum efforts and areas prone to rupture. Dosing and Capping & sealing, complemented with a transport action based on a conveyor belt make up the entire process line. The dosage stage consists of a hopper for storing the raw material in whose base it has a gate governed by a pneumatic actuator, which in its open or closed state, will determine the dosage of the solid. Capping and sealing has two pneumatic actuators that in combination, one of them enables or blocks the displacement of the lid to the jar in turn, and the another one is charged by means of pressure and blow seal. In the control system, the Arduino MEGA embedded system was set as the engine of the resources management of the process (sensors and actuators), the embedded system Arduino MEGA. For the monitoring system, an application on the QT Creator platform with support for Python mounted on a Raspberry Pi3 was developed. The integration of the Arduino and Raspberry Pi3 embedded systems by means of a serial communication made possible to obtain a robust control system with a real-time, and low-cost monitoring interface representing a valid option for the technification of the processes of SMEs.
