TECHNICAL SEMINAR VIRTUAL INSTRUMENTATION by Bibhu Santosh Rout Roll no # EI200118005 Under the Guidance of Ms. Suchilipi Nepak BIBHU SANTOSH ROUT
INTRODUCTION A virtual instrumentation system is computer software that a user would employ to develop a computerized test and measurement system for controlling from a computer desktop an external measurement hardware device and for displaying test or measurement data collected by the external device on instrument-like panels on a computer screen.
ADVANTAGES OF VIRTUAL INSTRUMENTS Lower costs of instrumentation Portability between various computer platforms Easy-to-use graphical user interface Graphical representation of program structures Code can be compiled to standalone .EXE or .DLL file TCP/IP connectivity (Web server integrated into virtual instrument)

Lab VIEW is a graphical programming language that uses icons instead of lines of text. Lab VIEW is an integral part of virtual instrumentation. A virtual instrument consists of an industry standard computer or workstation equipped with powerful application software, effective hardware, and driver software. LAB VIEW
Front pane: Serves as the user interface. Block diagram: Contains the graphical source code that defines the functionality of the VI. Icon and connector pane: Identifies the VI so that you can use the VI in another VI. A VI within another VI is called a sub VI. A sub VI corresponds to a subroutine in text-based programming languages Interfaces of a VI
Virtual instrumentation is fueled by ever-advancing computer technology and offers you the power to create and define your own system based on an open framework. LabVIEW was designed with scientists and engineers in mind, providing powerful tools and a familiar development environment created specifically for the design of virtual instruments. Conclusion
