Day 1 and 2: Introduction to Labview

The first and the second day of the workshop delved into the basics of LabVIEW, providing participants with a solid foundation. Mr. Gurumoorthy Associate Professor, Saveetha College of Engineering, an expert in LabVIEW, took the reins, guiding attendees through a comprehensive session. The day commenced with an overview of LabVIEW s interface and key features. The graphical programming paradigm, where code is represented by interconnected icons and wires, was introduced, fostering an understanding of LabVIEW s unique approach to programming. Participants were then introduced to the concept of virtual instrumentation, wherein LabVIEW serves as a platform to create custom virtual instruments for data acquisition, analysis, and control.

Hands-on exercises formed an integral part of the session, allowing participants to engage directly with LabVIEW. They were tasked with creating basic virtual instruments and programming logic to control LED lights. This interactive approach ensured that theoretical knowledge was immediately put into practice, promoting a deeper understanding of the concepts.

Day 3: Signal Processing

The workshop s third and fourth days transitioned to more advanced topics, focusing on signal acquisition, processing, and image manipulation. The sessions were expertly led by Ms. K. Yavana Rani, a distinguished personality from the Ministry of Defence Research & Development Organisation (DRDO), Avadi. Ms. Rani s extensive experience in the field added a layer of practicality and real-world insights to the workshop.

The sessions on signal acquisition delved into the various techniques and considerations involved in capturing data and were guided through the process with LabVIEW.The practical implications of signal processing were underscored through interactive demonstrations, where participants witnessed the transformation of raw data into meaningful information using LabVIEW.

Day 4: Image Acquisition and Processing

The second segment of these days was dedicated to image acquisition and manipulation. Ms. Yavana Rani provided insights into image acquisition techniques, discussing topics like camera interfaces and image formats. The participants were then introduced to image processing tools within LabVIEW, allowing them to explore operations like edge detection, image enhancement, Image inversion and color manipulation.

The combination of theoretical discussions, practical demonstrations, and hands-on exercises enabled participants to grasp the intricacies of signal acquisition, processing, and image manipulation, setting the stage for more complex applications.

Day 5: SRD,USRP

The fifth and final day of the workshop witnessed a continuation of the advanced themes, with Ms. Kalpana Devi taking the reins. Ms. Kalpana Devi, an Associate Professor in the Electronics and Communication Engineering (ECE) Department at VelTechRangarajanDr.Sagunthala R & D Institute of Science and Technology, brought a wealth of knowledge to the table.

The day commenced with an exploration of LabVIEW s capabilities in state-based programming. The State Mission design pattern was elucidated, enabling participants to design systems that transition between different operational states seamlessly. This concept found relevance in numerous real-world scenarios, such as industrial automation and control systems. The importance of clear and precise documentation in engineering projects was highlighted through an overview of System Requirement Documents (SRD).

The workshop then ventured into the realm of Software-Defined Radio (SDR) using Universal Software Radio Peripheral (USRP). Ms. Kalpana Devi explained the principles of SDR, emphasizing its role in enabling flexible and reconfigurable communication systems. Participants were introduced to USRP hardware and were guided through the process of setting up a basic SDR system using LabVIEW.

The day s final segment centered on the Case Structure, a fundamental programming construct in LabVIEW. Dr.Kalpana Devi elaborated on the significance of the Case Structure in managing complex decision-making processes within a program. Practical examples demonstrated how the Case Structure enhances code modularity, readability, and maintenance.

In Conclusion, the five-day workshop on LabVIEW and its applications proved to be a transformative journey for participants. The integration of theoretical insights, practical demonstrations, and hands-on exercises ensured a well-rounded learning experience. The guidance provided by distinguished experts,Mr. Gurumoorthy.G. , Ms. K. Yavana Rani, and Ms. P. Kalpana Devi, enriched the workshop with real-world perspectives and industry best practices.

Participants emerged from the workshop equipped with a deep understanding of LabVIEW s interface, functionality, and applications. They gained knowledge in signal acquisition, processing, and image manipulation, and were introduced to advanced concepts such as state-based programming, System Requirement Documents, and Software-Defined Radio.The workshop undoubtedly ignited a passion for leveraging LabVIEW s potential in their academic and professional pursuits, contributing to the ongoing advancement of engineering and technology.
