ENG 192: Hands-on LabLab 1: Data Acquisition with LabVIEW™Engineering Disciplines Explored: AllIntroductionThis lab will cover the very basic elements of data acquisition and analysis using the graphical programming language, LabVIEW. LabVIEW is a programming language that uses visual icons instead of text to formulate a program. By placing LabVIEW functions onto a LabVIEW program and “wiring” them together a program is built. While it is mostly used for data acquisition programs due to its ease of use, LabVIEW is built on topof C and can be made to do virtually anything in the hands of a powerful user. The main idea of using a programming language like LabVIEW is to be able to put together a data acquisition system very quickly. LabVIEW was designed for engineers and scientists to be able to acquire and analyze their data while spending a minimal amount of time setting up their experiment. Also, since LabVIEW is a visual language there may be less of a learning curve than some of the text based languages. Also, LabVIEW isn’t meant to just collect data but to present it to the user in the form of graphs and indicators so that the user can use one program to meet their need of acquiring, analyzing and presenting data using a computerThe lab will be split into two parts performed in teams of two students. One part will require students to analyze a set of prerecorded traffic speed data in a similar manner as was done during the spot speed study. For the other part students will measure the duration of a one-use camera shutter using a light probe. Both parts will require the students to first create a program in LabVIEW to perform these tasks.Lab ExperienceThe lab experience is divided into two parts which should be done in a two person group. It does not matter in which order they are completed.Part1 – Analyzing Traffic Speed Data with LabVIEWSome data is available which mimics traffic speed data that may have been taken during the Spot Speed Study from ENG 191. The purpose of this exercise is to build a LabVIEW Virtual Instrument to read in that data and to analyze it. The instrument will determine the mean, median, mode, and standard deviation of the data as well as produce the frequency response and cumulative frequency response plots. Please follow the instructions provided at your lab bench for this exercise.Part2 – Measuring the Shutter Speed and Flash Duration of a Disposable CameraFor this exercise, the students will build a virtual oscilloscope in LabVIEW to measure the shutter speed of a one-use camera using a light probe. The result will be a pulse of a certain duration which will be shown graphically and will also be automatically measured and indicated numerically. Please follow the instructions provided at your lab bench for this exercise.Lab ReportThere is no formal report required for this lab. In order to receive credit, each group of two students must turn in the printed screen capture of the Block Diagram for both lab exercises. In addition, the Front Panel screen capture should be given for each result obtained for both lab exercises; this would be three result screens for Part1 and one result screen for Part2. The recommended way to print the screen captures is to first capture theactive window with the keyboard command “ALT - PrtScrn”; this will copy the active window to the clipboard. Then create a new Word document and paste the clipboard image to the document. Please also label each image with a descriptive identification and include your names and seat numbers with the
