Implementation of virtual laboratory for online e-learning of control and Instrumentation courses

Implementing a virtual laboratory for online education in control and instrumentation courses, promoting collaborative learning and sharing of resources among universities to enhance practical learning for students. The project aims to address fundamental engineering concepts using simulations, virtual labs, and remote access to real equipment. The architecture includes a hybrid mode of lecture and online experiments, customized controls, and reports generation. Students can remotely operate instruments, design experiments, and benefit from shared high-cost equipment. The project timeline spans two years with 10 weeks per laboratory setup.

Presentation Transcript

  1. Implementation of virtual laboratory for online e-learning of control and Instrumentation courses • R.Anandanatarajan M.E.,Ph.D. • Professor & Head, • Department of Electronics and Instrumentation Engineering, • Pondicherry Engineering College. • Puducherry 605 014. www.pec.edu

  2. Motivation • Creating virtual laboratory and a community of young learners, teachers and researchers to explore collaboratively the practical aspects of Engineering curriculum . • Significance and importance of laboratory work in E-Learning • Internet provides connectivity everywhere and broadband access enables high capacity connections. • Non – Availability of high-cost equipments in all universities. • Why not we Collaborate different universities in India and share the Laboratory resources for quality education.

  3. Project Objectives • To implement online virtual & Remote laboratory for Engineering curriculum of Electronics, Control & Instrumentation Engineering. • To determine what set of fundamental concepts can be addressed in a laboratory environment for Engineering Curriculum • To parse each experiment undertaken into pieces that can be addressed • by simulation, • by Virtual lab using stored experimental data • by actual manipulation of equipment remotely. • To collaborate and share the laboratories of different universities.

  4. The Innovation Statement • Collaborating and cooperating universities by sharing lab resources will offer cooperative programs of studies. • Laboratory ware will be usable for many different groups of learners • Open universities studies can be integrated

  5. Architecture of Remote Lab

  6. Course and Lab Integration Remote Lab • Hybrid Mode: Lecture in Class and experiment conducted on-line. • Each experiment can be conducted in three phases: • Simulation • Virtual lab using stored experimental data • Remote access & operation of real equipment Physical Lab

  7. Online Laboratory Teaching Model • Custom built simulation package designed for virtual laboratory. • Remote experiment uses SCPI, Run time Active-X for each experiment with web services. Pre-Lab Orientation video Model and laboratory update Simulation Feedback and Remote Continuous Experiment Improvement Report and Knowledge Evaluation

  8. Simulations Used as Laboratory Primer – Functional verification

  9. Experiment Implementation Instrument Bus Instrument-1 Web Services Experiment Module Instrument-2 • Example operation of remote Laboratory • Instrument screen and controls available on client interface • Students access through Active-X plug-in on web browser

  10. Virtual Laboratory Features • Remote lab interface • Customized controls – more like actual instrument • Online charting facility. • Report Generation facility

  11. Remote Laboratory – Web Implementation

  12. Survey on our students

  13. Implementation • Design of Programmable Electronic Test Bench Hardware for the implementation of Virtual Laboratory. • Implementation of Communication interface between the hardware and server end. • Web services Design with ETB server and client – Deploying Active-X runtime libraries. • Integrating the Electronic Test Bench (ETB) for various Virtual Laboratories. • System Validation ,Testing and Launching.

  14. Our Expertise - Existing online remote Lab - Intranet Based.

  15. Budget Estimates Recurring Non-Recurring

  16. Non recurring Expenditure

  17. Time Frame per Laboratory Procurement of equipments 2 weeks ETB Design 2 weeks ETB Development 4 weeks Web Services Deployment 1 week Testing and Validation 1 week Total 10 weeks per Laboratory For completing all the 10 labs the time frame requirement is 100 weeks in total. The project duration would be for 2 years. Total Time Frame

  18. Scope and Use • Students can remotely operate laboratories • Laboratory instruments can have multiple student users • Students can "design" their own experiments • High-cost instruments can be shared • Students can use resources efficiently • Virtual laboratories can become part of distance-learning curricula • Standardization of course/laboratory format • Enlarge the availability of teaching/ training material • Collaborating and sharing lab resources from different universities.

  19. Thank you.
