Desenvolvimento e teste de um sistema embarcado para o controle de uma guia de solda

Abstract

The embedded systems are computers which are part of all the industries and are used for multiple purpouses, from data aquisition from a parking sensor to the gas administration of a rocket. This work presents the project, development and testing of an embedded system responsable of controlling a linear soldering machine. Its objective is to construct a low cost system which acts as a Man-Machine Interface, executing precise soldering routines in addition to addressing the challanges and solutions of developing it with restrict hardware access. The system is composed by a microcontroller conected to a display, buttons, sensors and stepper motor drivers. The development has been listed in seven main stages: the requirements gathering; the partitioning between hardware and software; the studying of the devices; the drivers’ development; the operational system’s tasks organization and the embedded systems testing. At the end of this project, it was possible to control a three axle machine in real time, as well as using it to solder steel profiles with a coupled MIG welding machine.
