Analysis and report features of LabVIEW 2010


LabVIEW 2010 includes hundreds of signal processing and analysis functions, which can better analyze your measurement data. Using the report generation function of LabVIEW 2010, you can summarize and sort out the analysis results, so as to better present them

analysis and report

analysis and report is a term that refers to the integration of data processing or report generation functions in data collection applications. When you collect data from a function, such as DAQ assistant, you can simply connect the data to the analysis function block, and the collected data will be analyzed

Figure 1 Using LabVIEW's data flow programming, analysis and reporting are integrated with data acquisition

LabVIEW 2010 contains hundreds of analysis and mathematical functions dedicated to the engineering field. These functions are built in by LabV, which is one of the 15 important scientific research and innovation bases of central enterprises planned by the central Organization Department and the state owned assets supervision and Administration Commission of the State Council in Changping District, Beijing. Table 1 summarizes many built-in analysis functions. Analysis functions used in special fields can be found through LabVIEW toolkit and modules. Table 1 LabVIEW contains thousands of built-in engineering domain specific analysis functions

LabVIEW 2010 improves some analysis functions and adds new analysis functions. These functions are mainly used for advanced signal filtering, waveform generation and processing, thus further expanding the analysis ability of LabVIEW. Table 2 shows some new or improved analysis functions in LabVIEW 2010. Table 2 By improving and adding new analysis functions, LabVIEW 2010 further extends the analysis capabilities of LabVIEW

MathScript node

through the MathScript node, you can import existing M file to LabVIEW graphical programming environment for hybrid programming. In the data flow programming mode, the advantages of text-based mathematical functions can also be used, so that the existing text-based mathematical functions can be reused. This node is compatible with real-time systems, that is, you can embed it The LabVIEW code of m file script is seamlessly deployed to the real-time hardware of Ni to realize the analysis function in the real-time operating system

about integrating customization in LabVIEW For more information about the m file, please visit: using LabVIEW MathScript real-time module to deploy mathematical programs with text architecture to real-time hardware

DLL library and Net assembly

using the call library function node of LabVIEW, you can call shared libraries in your LabVIEW code, such as DLL (Windows focuses on providing customers with more accurate test data), or framework (MAC OS X)

you can also use LabVIEW Net constructor node call Net assembly, and then call Net object, and finally import or export Net object

generate reports and save data

the report generation palette in LabVIEW 2010 includes the underlying VI and several express VI, which can help you configure and create reports containing VI files or data collection and analysis results. Using these VI, text or HTML type reports can be generated at the same time of data collection and analysis. You can either save the report to a file or send it to a local or network printer by programming

if you want to create more advanced reports, you can use the LabVIEW report generation toolkit for Microsoft office, which extends the function of programming and creating reports in Microsoft word or Excel for all industries

Figure 2 The LabVIEW report generation toolkit for Microsoft office allows you to create more advanced reports in Microsoft word or excel

in LabVIEW 2010, you can export tables, arrays, oscillograms, and data in oscillograms to software, such as Ni diadem or Microsoft Excel. After exporting the data in LabVIEW (by saving to file or exporting from waveform chart), you can use professional post-processing software, such as diadem, to interactively display and analyze the measurement data, or create, import and export WYSIWYG report template

Figure 3 In LabVIEW 2010, you can use the WYSIWYG reporter of diadem to export data in graphs or charts manually or programmatically. The functions of LabVIEW can save data in various formats, including text (txt), comma separated value files (CSV), and more flexible high-performance file formats, For example, technical data management flow (TDMS)

uses LabVIEW 2010 and diadem 2010 for offline analysis and reporting

for the complex application of data acquisition and processing, you can also divide it into two simple parts, namely, data acquisition part and data processing part. Under this architecture, changing or adding one part will not affect the other part

Figure 4 Offline processing separates data collection and analysis report. This method is more modular and easier to expand

using offline analysis report method, you can easily divide the work in the team. One developer is responsible for data collection, and the other is responsible for analyzing the collected data and generating reports. In some cases, especially when evaluating the test process, you may want to compare the measured data with the original data. At this time, offline analysis is a good method. Moreover, in order to prevent oil leakage under high pressure, after separating the data acquisition and analysis report, you can use other software tools for interactive offline analysis, such as diadem

in data acquisition applications, diadem, as a professional post-processing software, is a natural extension of LabVIEW 2010 tool chain. Using diadem software can process a large amount of raw measurement data, which greatly reduces the time from the data collection stage to the final analysis decision

use Ni DataFinder to find and load data in diadem or LabVIEW

diadem includes a technology called Ni DataFinder, which can automatically search the local computer and index the description information stored in the measurement file. This technology can be used in LabVIEW through the LabVIEW DataFinder tool package. You can also use dataplugins to configure Ni DataFinder to parse the description information in any custom data file format, so as to load the information in the file in LabVIEW or diadem

Figure 5 Ni DataFinder can be seamlessly combined with diadem and LabVIEW to help you build queries,

so as to quickly locate your data

use diadem in data analysis

like LabVIEW, diadem contains hundreds of analysis tools, which can be used in common engineering applications, including statistical analysis, histogram operation, common mathematical applications, curve fitting, signal processing and filtering, three-dimensional operation and matrix operation. Each analysis function is based on configuration, that is, you can use the configuration dialog box to select the corresponding operation parameters, and even preview the results before the actual operation. Using diadem for complex analysis does not require programming

Figure 6 Diadem contains hundreds of analysis functions, which can be configured and executed without programming

create professional reports and templates in diadem

after analyzing the measurement data, you often need to create professional reports in order to share the results with colleagues, suppliers or customers. In diadem, you can use WYSIWYG to create reusable report templates, and then output the reports to HTML, PDF, PowerPoint, printers, and pictures in all common formats

Figure 7 Diadem can create professional reports and output them to PDF, HTML, PowerPoint, pictures, etc.
