Visualization of virtual environment through labVIEW platform

Abstract

Abstract Virtual instrumentation is the use of customizable software and modular measurement hardware to create user-defined measurement systems, called virtual instruments. The primary difference between hardware instrumentation and virtual instrumentation is that LabVIEW software is used to replace a large amount of hardware. The software enables complex and expensive hardware to be replaced by already purchased computer hardware. Virtual Instrumentation is established using LabVIEW. Laboratory Virtual Instrument Engineering Workbench (LabVIEW) is a system-design platform and development environment for a visual programming language from National Instruments. The graphical language is named “G”; not to be confused with G-code. Originally released for the Apple Macintosh in 1986, LabVIEW is commonly used for data acquisition, instrument control, and industrial automation on a variety of Operating Systems (OSs), including Microsoft Windows, various versions of Unix, Linux, and MacOS. Simple timer Circuit, Traffic Light Control System, Automotive Safety assurance, Speed, Direction control of DC motor and Library Database File Management are realized by implementing VI programs. Select switch, Looping concepts, Case and Flat Sequence structures, String Manipulation, Clusters, File IO systems and Arduino interfacing through DAQ are used to implement all Simulation Models. Software Developed timer circuit and Automotive Safety assurance overcome the accuracy problem of conventional circuits. Designed Library Management system enhances ease of tracking. Conventional control of DC motor relies on hardware accessories such as Field and Armature rheostats and it requires manual implementation, whereas Virtual instrumentation makes software based control and it improves the system reliability. Fetching of Real time data and manipulation addresses the flexibility issue of hardware based Traffic Light Control system.
