Electronic Instrumentation Virtual Laboratory

  1. 1. Design of an Electronic Instrumentation Virtual Laboratory based on Free-Open Resources Gustavo Meneses Ing. Eléctrico UNALMED Esp. Automatización Industrial UdeA Msc. en Ingeniería UdeA Universidad de San Buenaventura
  2. 2. Motivations Over the last decade a complete plethora of free-open hardware and software resources have been developed for use in engineering and other fields [4], more recently significant advances have been achieved in the field of microcontrollers [5] and data acquisition and analysis [6]
  3. 3. Motivations Virtual laboratories have become an extended tool used for teachers and students around the world in all stages of education, ranging from elementary school to higher education[1]. The virtualization of laboratory practicals has shown to be an effective mean to extend learning scenarios beyond the classroom or laboratory at campus site.
  4. 4. THREE WIDELY KNOWN FREE-OPEN RESOURCES THAT CAN GET INTEGRATED INTO A VIRTUAL LABORATORY
  5. 5. Requirements and functional arrangement for electronic instrumentation virtual laboratory
  6. 6. Project's Goal  The main goal is to design and implement a set of practicals belonging to the Electronic Instrumentation course for the Electronic Engineering undergraduate program.  Laboratory practicals on temperature sensing, error estimation, data acquisition, remote monitoring and sound analysis have been designed to be integrated to course virtual activities
  7. 7. MAIN HARDWARE-SOFTWARE COMPONENTS FOR THE OPEN SOURCE WEB-BASED PROPOSED VIRTUAL LAB FRAMEWORK
  8. 8. Self-made USB Pinguino board to support the virtual laboratory circuit and hardware setup for the practicals
  9. 9. Hardware and circuit setup for the implementation of a practical on temperature sensing and data acquisition
  10. 10. Integration scheme for the hardware and software components of the electronic instrumentation virtual laboratory
  11. 11. General overview of the Virtual Laboratory operating scenario
  12. 12. Conclusions  Current free-open tools exhibits acceptable performance and offer to users and administrators enough options to design and put into operation, implementations covering the essential needs for virtual practicals.
  13. 13. Conclusions  Virtual laboratories and similar e-learning tools improve and complement traditional “atclassroom” education instead of abolishing it.
  14. 14. Conclusions  The solution based in open-free resources has flexible features that enhance time sustainability. The less dependent design on hardware-software elements, allows a wider spectrum of operating variants, including the adoption of teaching approaches or models dynamically, as time passes according to academic results.
