Diseño e implementación de un módulo de instrumentación electrónica, enlazado con Labview mediante interfaz USB

Abstract

It exposes the design and implementation of an electronic instrumentation module with USB communication for data transmission between the module and user interface developed in Labview. This module will be used in Instrumentation Laboratory of National Polytechnic School. It has a system for temperature control inside the module from environment temperature to a maximum temperature of 60ºC, the module allows speed control of a DC motor, the control of a servomotor and the control of movements of an assembly of Solidworks, through the link between Labview and Solidworks. In addition, the module provides the following resources: 8 digital inputs and 8 digital outputs, analogical inputs and outputs of voltage (0-5 VDC) and current (4-20 mA), 2 relay outputs, 2 PWM outputs. The user interface has tabs in which there are distributed controls and indicators related with module’s resources and systems. The module was developed using PIC and AVR microcontrollers. The interface developed in Labview allows control the module and enables its usability. Tests showed that all available resources are operational and functionally correct.
