The applications of electrical circuits, electromechanical energy conversion devices, power electronics converters, power systems and electrical machines and in engineering education can be tested with pure-simulation or by the real-measurement using hardware equipments. Virtual Projects using LabVIEW Electrical and Electronics Engineering These controls include knobs, dials, push buttons, sliders, strings, etc., which supply the data block diagram. This front panel allows the user to pass the inputs and to receive the outputs. Various controls and indicators are selected from the control palette which is available only on the front panel. The front panel is a user interface which is used to display controls and indicators. Each VI consists of three elements such as the front panel, block diagram and sub VIs. LabVIEW programs are called VI’s (Virtual Instruments) as their appearance resembles operations of physical instruments such as oscilloscopes, multimeters, etc. And wires are used to connect these nodes therefore, a node can be executed when all the input are connected through these wires. Each element in the LabVIEW is considered as a node which may be input or output. It is a graphical based programming language used to develop measurement, test, and control systems, data analysis applications using inbuilt graphical functions and wires that resemble a flow chart.Īs compared with C++, visual basic, Java and other text-based languages that their program execution is determined by the sequential order of the program elements, LabVIEW follows the data flow for executing the applications. LabVIEW stands for Laboratory Virtual Instrument Engineering Workbench, developed which is developed by National Instruments. Introduction to LabVIEW Programming Software Therefore, before discussing some of these virtual laboratory experiments by LabVIEW programming, lets us learn the basics of LabVIEW. These virtual laboratory exercises provide a new approach of collecting and analyzing the scientific data and also gave the opportunity for students to develop their skills in programming by virtual instrumentation. The LabVIEW based laboratory experiments and projects enable students to integrate various applications so that they can acquire, analyze and present the loads behavior virtually. Even though we can create and control various projects using LabVIEW with dedicated data acquisition (DAQ) hardware, more economically and to reduce the feasible time constraints, virtual laboratories and projects are introduced. In spite of this, we can create the virtual prototype models of real-time systems by incorporating LabVIEW programming language to engineering projects and experiments. Latest projects and experiments in engineering applications are used to simulate the actual job conditions which are bound to a specific hardware and circuit components. Its kind of like how the byte counting of the golfing languages can encode things in there.As a rapid prototyping tool in various measurement and control engineering applications, LabVIEW allows to implement a wide variety of real-world relevant laboratory experiments. Call them "LabVIEW Primitives" or "weighted fundamental graphical programming primitives" - but not bytes.Īnother (better?) way of getting an idea of how much information is in a given LabVIEW file is to take the save file for it, and compress it with a standard compression program at maximum space efficiency - and that is how big the 'program' is. Golfing LabVIEW according to some scoring system is fine, but calling them bytes and comparing them with languages that actually use characters is like comparing apples and oranges. Otherwise, this feels very much like "I'm going to write in C, but I'm going to count if as one byte and switch(x) as four bytes". The necessary thing is to be able to represent the program in text, and be able to convert it back to the same program in LabVIEW via a mechanical transformation. While this may be a significant undertaking, consider trying to figure out how to represent the LabVIEW structure in JSON or another structured data language. However, the thing that should be examined is the way to represent the labview in such a way that one could take the text representation and covert it back into a working graph. I'm not going to claim that this the most efficient storage (that particular one goes on for 2465 lines). When you actually dig into the file that is saved, it turns out to be an xml file. The main thing I'm bringing up here is the interface. Some time ago, there was a program for the Mac called " Quartz Composer" use for doing some graphic things.
