Filter for table data, the range of data obtained and defined 2D

I produce data of an ultrasonic sensor at 1 K Hz, and there is a lot of data (data points range of 0 to 10). However, in some cases when I know that the data should be about 7 (for example) I get outliers (about 9 and 10). Is it possible to define a filter for data in the defined range.

I averaged the data to get an average value, and outliers are distorting. In the worst case, my outliers are 30 to 40% of the data generated. I created a filter to sort the data and, taken from the lowest value. I stop the loop when data reaches a value greater then 9. But this seems to take a long time (because the loop checks for each data point and there are 1000s of them).

Is there a better way to filter data and define a predefined table range to collect?

I enclose my filter.vi... and a set of samples of my previous data. The ranges of data of 10-8 and would like to have the range 7.5 to 8.5 to consider. The sensor records tension here and the problem can be solved by installing a different type of sensor, but if a filter in LabView can due it, the sensor that we use now is absolute.

I am in kind of emergency, my design in unfinished because of this problem, if someone can find some time to share some suggestions, I will be grateful.

Thanks in advance.

See attachment.  I have incorporated the data you've posted in the vi.  It doesn't seem like any data were less than 8.7 or so, so I modified the scope so it would be a few points on average.  Some games were completely out of reach while the average came back like NaN (not a number) due to a division by zero.

  • How to export data to excel that has 2 tables with the same number of columns and the column names?

    Hi everyone, yet once landed upward with a problem.

    After trying many things to myself, finally decided to post here...

    I created a form in form builder 6i in which clicking on a button, the data gets exported to the excel sheet.

    It works very well with a single table. The problem now is that I cannot do the same with 2 tables.

    Because the tables have the same number of columns and the columns names.

    Here are the 2 tables with column names:

    Table-1 (MONTHLY_PART_1) Table-2 (MONTHLY_PART_2)
    SL_NOSL_NO
    MODELMODEL
    END_DATEEND_DATE
    U-1U-1
    U-2U-2
    U-4U-4
    ..................
    ..................
    U-20U-20
    U-25U-25

    Given that the tables have the same column names, I get the following error :

    402 error at line 103, column 4

    required aliases in the SELECT list of the slider to avoid duplicate column names.

    So how to export data to excel that has 2 tables with the same number of columns and the column names?

    Should I paste the code? Should I publish this query in 'SQL and PL/SQL ' Forum?

    Help me with this please.

    Thank you.

    Wait a second... is this a kind of House of partitioning? Shouldn't it is a union of two tables instead a join?

  • Take the minimum value for table data

    I'm storing test data in a table, with the hope that I can output the minimum value of the data. So far, I have used the table of max/min but can't make it work how I want. The test runs continuously in a loop of the holder. I get the minimum values in the table, but I would like to change the number of samples that the table contains, before it generates a minimum. The other option is that I run the test for a period of time (e.g. 3 seconds) and the table stores the data for this time then output 1 minimum value for the entire period.

    My current configuration VI is attached.

    Very appreciated

    Chris

    The size of the array in your VI is determined by the number of samples that you collect in your DAQ assistant, who is now 100 samples.  Never more, never less.

    How many samples do you want before you determine the minimum?

    Maybe what you really want to do is to build the table in the while loop and store it in a shift register, and when the loop has repeated enough times, then you take the minimum of built table.

  • Filter for waveform data

    Hello world

    I'm trying to filter the noisy analog inputs of 10 channels (DC). I'm sampling of 100 samples/channel at 1000 Hz. My idea is to filter the data with a low pass filter (cut to 10 Hz 3rd order butterworth low freq) and then to calculate the average of each package of 100 samples. Finally, I would like to receive values at a rate of 10 Hz, which can be displayed on the front panel and be written in a file of measures.

    My problem is the following:

    The Express filter VI does not filter continuously after that the VI began. It seems to reset each time the loop runs. The table of 100 samples (white) before and after (red), the filter appear in the image "filterResponse". If I take the average of this table, it is of course less without the filter due to the transitory values between 0 and 0.025 s. I built a simplified version of my VI with only one channel using the VI "Simulate signal" and my concept seems to work well which is permanently (see "filterMeanExample.vi"). I get the idea that it might have to with the kind of dynamic data that is supported by many express VI. But since I'm on the VI KEITHLEY, I do not use the type of dynamic data. In fact, I had to convert a waveform data type to get a vehicle appropriate for the file of the measurement of its release.

    I wonder how to keep the filter VI of reset each time that the loop runs.

    My VI is rather large and contains the KEITHLEY 'Acquire signals' VI which most people do not have in their libraries, so I decided to show only the images.

    Thanks for your help!

    Phil

    System: WinXP, LabVIEW 8.2.1 Professional

    Thanks for the tips, I am set!

    I used the VI of butterworth filter in the tool box to filter on the Panel of the Signal processing that accepts the type of table data. I put the variable ' init/cont' true to prevent the filter to reset its initial States to 0. I guess, it was my real problem before. The Express filter VI doesn't have this option, so I wasn't aware of this feature.

    However, an image of the current value is attached.

    Thanks again,

  • Looking for table of the physical limits on ESXi 4.1

    Hello

    I searched for some kind of table showing the difference between the editions ESXi 4.1.  But I always got the data from version 5 instead of 4!

    I am particularly interested to know the limit of memory for each virtual on ESXi 4.1 computer free and paid editions.  Well, my vSphere client tells me that my free license gives me 256 GB limit on the host hardware.  That's more than enough.  But what about memory for each virtual machine?  What limit?

    If someone is able to find this table, I appreciate it.

    TIA

  • Table data collection and using other calculations

    Hi all!

    I have a table with the information (values), I want to read and collect the 4 values in the table. These must serve more than calculations.

    Take a scenario:
    Let's say the row index is 2.5 and the column index is 5.6 (these values are other calculations), so I'd like to collect the values of the matrix, return (2.5) (2.6) (3.5) and (3.6). Thus, in the closest base to the index value of two integers.

    The next step is to use these four values make a bilinear interpolation (that's my problem), but in order to use them, I need to get them into a knot of formula.

    To sum up; How to collect and store the 4 values for further calculations.

    I hope I explained good enough!

    PS! I'm rather new on LabVIEW, love until now

    Sounds like what you are really looking for is 2D.vi interpolate. Check it out on the range of mathematics under the Interpolation.

    Or you use another type of interpolation function?

    No need to reinvent the wheel if your 2D table represents just the nodes on a surface.

  • Prepare disks for ASM (data files and FRA)

    I intend to place data files on a disc 1 (sd1) and disk2 (PSD) when the backup of files (FRA) on disk3 (SDC). Here's how I'd do:

    For data files
    Disk1 is divided into a single primary partition (with native Linux what ID 83 not formatted system)
    Disk2 is also divided into a single primary partition (with native Linux ID 83 system not formatted)

    oracleasm createdisk vol1/dev/sda1
    oracleasm createdisk vol2/dev/sdb1

    CREATE DISKGROUP DATA EXTERNAL vol1, vol2 REDUNDANCY;


    For backup FRA

    Disk3 is partitioned into four primary partitions: / Boot (ext3), / (ext3), swap (swap) and /u01 (ext3)

    The FRA will be put under the/U01 and then attend the ASM:

    oracleasm vol3/dev/sdc4 createdisk
    CREATE DISKGROUP DATA EXTERNAL vol3 REDUNDANCY;

    Now, the problem. (1) the/U01 has already be formatted in ext3; (2) Oracle (DBMS) software will also be place under/U01

    It will be a problem?


    Otherwise, I can put FRA on the same drive as the data files, i.e. on disk1 and disk2. In this case, I need to partition the disk 1 in two primary parititions sda1 and sda2 (native Linux system ID 83 not formatted), one for data files and another for FRA (do the same for disk2). The downside is that the data file and the file recovery will be on the same hard drive.


    Please offer some suggestions.


    Thank you

    PS: in the environment of production, all the disc 1, 2 and 3 will be on hardware RAID 1.

    RAID 1 will protect you only a device failure. It won't protect you partition, the file damage system or user errors; It will be in the image of the errors and problems like any other data.

    So what happens if you delete by mistake / U01 or some other accident happens and you loose that partition? With your current setup, you will lose everything and will not be able to restore or recover the database. Put tablespaces FRA and DB on the same physical device is certainly a very bad idea, whether or not it is a RAID.

    ASM is not a software RAID 1 mirror. It ensures redundancy of data based on file extensions and knows about files of Oracle database, which is a very good thing. You probably do not want to specify 'external redundancy.

    In a production system, you'll certainly want to mux the critical data and to store the DB controlfiles, redo logs and finally archivelogs on media separate physically in order to avoid the single point of failures wherever possible. You can use partitions and volumes in ASM, but they should be separate physical drives, otherwise you will bypass the ASM data redundancy. You must also have a solid strategy for RMAN backup. The FRA is supposed to store backupsets RMAN, copies of the image, the important archivelogs and multiplexes of the copies of the database files and should therefore always on a separate physical disk.

    Unless you simply play, I strongly suggest that review you your current configuration.

  • [ADF, JDev12.1.3] I would like to stress that af: table takes the entire width of page and column auto-augmenter/reduce their width in proportion to the amount of available space. How...?

    Hallo,

    I see that default ADF makes all the 100px wide columns and there is the possibility to stretch a column to take full available width.

    I would like to know if there is a function / approach in ADF which - occupies all the available space - auto-calcule the width of each column to 1) the width of DB fields and 2) space in the browser window.

    I could also set the with columns of table in columns (characters) or (better?) in pixels and the framework should only for reproportion widths according to the available width.

    Or track to follow is defining the width of the columns in the table (percentage) property?

    Thank you

    Federico

    There is the possibility to stretch a column to take full available width.

    AFAIK, you can stretch several columns (read the docs for this property)

    I would like to know if there is a function / approach in ADF which - occupies all the available space - auto-calcule the width of each column to 1) the width of DB fields and 2) space in the browser window.

    (1) as far as I know, no

    (2) you can add class AFStretchWidth to the styleClass property to af:table (or surround your table with af:panelCollection and add this style class here)

    Or track to follow is defining the width of the columns in the table (percentage) property?

    Is probably not.

    % has different interpretation in different browsers, so you should use the style class AFStretchWidth.
