  1. 1. <ul><li>Presented by :- </li></ul><ul><li>Arpit .S. Sharma </li></ul><ul><li>(Electronics & Communication) </li></ul><ul><li>5 TH SEM (B) </li></ul><ul><li>Roll no:- 090460111085 </li></ul><ul><li>UCET </li></ul>
  2. 2. 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.
  3. 4. <ul><li>Lower costs of instrumentation </li></ul><ul><li>Portability between various computer platforms </li></ul><ul><li>Easy-to-use graphical user interface </li></ul><ul><li>Graphical representation of program structures </li></ul><ul><li>Code can be compiled to standalone .EXE or .DLL file </li></ul><ul><li>TCP/IP connectivity (Web server integrated into </li></ul><ul><li> virtual instrument) </li></ul>
  4. 7. VIRTUAL LABORATORY
  5. 8. <ul><li>Computer and Display </li></ul><ul><li>Software </li></ul><ul><li>-Driver level software </li></ul><ul><li>- Register Level Software </li></ul><ul><li>-High-level tool software </li></ul><ul><li>Interconnect Buses </li></ul><ul><li>Instrument Hardware </li></ul>
  6. 9. INTERCONNECT BUSES <ul><li>SERIAL PORT </li></ul><ul><li>GPIB </li></ul><ul><li>PC-BUS </li></ul><ul><li>VXI BUS </li></ul>A VXI bus system controlled by GPIB
  7. 11. <ul><li>Lab VIEW is a graphical programming language that uses icons instead of lines of text. </li></ul><ul><li>Lab VIEW is an integral part of virtual instrumentation. </li></ul><ul><li>A virtual instrument consists of an industry standard computer or workstation equipped with powerful application software, effective hardware, and driver software. </li></ul>
  8. 12. <ul><li>Front pane : Serves as the user interface. </li></ul><ul><li>Block diagram: Contains the graphical source code that defines the functionality of the VI. </li></ul><ul><li>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. </li></ul><ul><li>A sub VI corresponds to a subroutine in text-based programming languages </li></ul>
  9. 13. User Interface of Tank Simulation
  10. 14. Graphical Code of Tank Simulation
  11. 15. <ul><li>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. </li></ul><ul><li>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. </li></ul>
  12. 16. <ul><li>THANK YOU … </li></ul>
