10 data kech. / S for 28 channels

Hi all

On the ground, I have 28 channels of sensor data, the data rate is 10KS/S for each channel.

I store the data field up to 3 months to create historical reports or analysis of the conditions on the ground.

The data is very large, so I want to hear from you all to store as much data techinique or preferred way to store as much data.

: mansurprised:

Thanks for your suggestions.

The requirements of the project are already set by the customer. The client wants to complete 10K to 28 channels. He cannot afford the minimum sample rate or data loss.

I tried with the TDMS files to store 10 kech. / S (size SGL) given to 28 channels (sine wave); the size of the file is approximately 3.5 GB for 1 hour. The full-day data come around 84 GB, I'm not sure of the size of the TDMS file that can support up to as much of the file size, if it does not then support once again, I have to save the data to the full day in the whole of the bunch of TDMS files. Now if the customer wants to see the full data report 1 time in graphical format or in a table the task to perform the action takes around 2 to 3 minutes or some time it came up with an error like "not enough memory". If at the end of the day if the user wants to see the report full day how I can provide the report who have such huge data.

I use the LocalSystem PXI RT with a hard drive. PXI have always given 7 days as a backup, or in case of failure of the connection with the server, the backup data is in PXI.

So my question now even than the database or a file format I have to chosse store comprehensive data.

If there is no techinque to compress data, please suggest me.

  • No data in WMC EPG for some channels after Microsoft abandoned zap2it to Rovi Corp. as a supplier EPG

    I received no data after July 21 in my EPG WMC of zap2it.  I have reset the TV signal using a slightly different zip code.  Now, I get ABC and Fox, Rovi data instead of zap2it, but not NBC, CBS and CW, which is a secondary string of the NBC Channel.  NBC and CW are 5 RF channel and CBS is channel RF 11.  These strings are not in the original configuration, I guess because they are not in the database of Rovi EPG for my region, Tri-Cities, TN-GO TNT antenna.  They are a search for additional channels and the signal strength is 100%.  But there is no data to guide them.  When I try to change the source of the list for the channel, it is said ' Don't Show no ads for this channel.

  • 2% USB 6361 C sampling for 8 channels

    What is the maximum rate for playback at the same time 8-channel USB 6361 map?

    I read the specification, and there is a line that says:

    Example Maximum rate... 2.00 MS/s single channel,
    1.00 MS/s multichannel (aggregate)

    When I tried to read 3 channels with sample rate 1 MECH. / s I have error: "Conversion ADC tried before the prior conversion was complete.
    I did some tests and it seems 500KS/s is maximum for 4 channels and 250 kech. / s max for 8.

    Am I missing something or is this how it works?

    aggregate refers to the total number of samples.

    This card uses a multiplexer to switch AD converter between the channels. SO not really simultaneous reading!

    One channel, no switching, fast 2 ms/s

    several channels: 500ns time to pass & set between channels, up to 1 ms/s left altogether, but you can read CH0, CH0, CH1 and CH2 that would give you 500kS/s CH0 and 250 kech. / s for CH1 & 2

  • Windows Media Center lost information Guide for some channels, but it is still on zap2it

    Why Windows Media Center (WMC) is no longer a information Guide for some channels, when she used to have?  WMC uses the information from zap2it.com and zap2it.com still has the elements of programming for these channels.  The Guide has "No data available" for all the hours for these channels.  For Los Angeles area broadcast, channels of first importance are 40.2 by 40.5 (40.1 is very good, as evidenced by the correct include titles and descriptions).

  • PXI 2720: Conection for Multi channels

    Hello

    I put implement the multiple channels with resistance adjustment at the same time.

    It is good to use '2720 Soft Panel', but I couldn't find the way to set up on my own Labview program using 272 X reference live

    For example, I want to implement chan0 (80 ohm), (120ohm) chan1, chan3 (100ohm) etc.

    I tried on one channel at a time. This is to give the new unstable resistance...

    Is it possible to using X 272 screw reference?

    Should I use "palett Ni272x-> advanced-> ni272x relay control multipe" fuction for their implementation?

    Thank you

    Insuk

    Hello Insuk,

    The NOR-272 x Resistance.vi for example is a good example of how define a single channel - to set multiple channels, call the 1Chan resistance ni272x 1Samp.vi to write for each channel you want to adjust.

    Make sure you that you connect also each channel to the connector had TO plug into the front panel when you need to use it.

    Here is an excerpt that should define a multiple channel resistance and connect these strings to the façade had TO connector:

    Note: you can set the resistance without connecting to the connector HAD / DMM and then only connect to the connector HAD / DMM when necessary.  I noticed that the '272 x Soft Front Panel' does not display the resistance of the channel if its not connected to a connector - the code snippet above to display the correct resistance in 272 x Soft Front Panel, but will also each channel link to the front panel.  Make sure what you want to do this before starting the extract.

    Make sure that you aren't opening and closing of the session each time you call the resistance VI write, this could cause you reset the unit each time, which would be left to zero all the other channels.

    I don't understand what you mean by «Who does give the new unstable resistance...» "If the code snippet above does not work, can you clarify on what is happening.

  • Definition of various mitigating factors for each channel on the virtual bench MSO

    I'm trying to measure two very different signals, using both channels of the 8012 virtual bench programmed in LabView. The signals are very different amplitudes, which means that the definition of the vertical range for the largest signal is not truncated causes the smallest signal to become very agitated that the resolution today is very low. The only way I know to use two channels simultaneously is to index the waveforms with channel number when the measurement is complete. This means that both channels of parameters are defined at the same time by the same command sequence. Is it possible to set separate settings for each channel during intialize?

    I enclose my referral program that there is much more than just this part. If someone need clarifications just ask!

  • lost sound for a channel of tv media Center in vista

    Hello world
    Have had my cable is split into a TV and my computer.  My computer using Vista and is updated.  This Setup has worked well over the years.  A few weeks ago a tv in media center channel lost his.  All other channels are fine.  My TV has sound for all channels.  I replaced the splitter and still the same problem.  I think media center units must be reloaded in my computer.  This problem can be corrected by removing and reloaded in my computer?  Or is there another place I have difficulty?
    Thank you

    Hi 01starsky,

    Cause of this problem

    This problem occurs because the Media Center always tries to play an (Arc consistency #3 algorithm) AC3 (Dolby Digital 5.1) audio stream that is present in a show. The AC3 audio stream offers the best quality audio experience. Some stations broadcast the required primary stereo stream and the AC3 audio stream option. If Media Center detects that an AC3 stream is available in the broadcast, Media Center selects that available stream. Some broadcasters may broadcast empty or muted AC3 stream. So, if a broadcast contains an AC3 stream, but no audio is present, Media Center has no sound for that specific channel.

    Currently, Windows Vista doesn't have an option to force Media Center to use the main audio stream when a muted AC3 stream is present. However, you can contact the broadcaster and report the muted AC3 stream.

    Reference:

    When you use Media Center to watch live TV on a Windows Vista-based computer, you can't always hear the sound

  • Library meets live TV with the error: "there are currently no TV signal detected for this channel. The channel may be temporarily off the air. »

    I recently changed my TV card to an analogue of Hauppauge PVR150 at a Hauppauge DVB - S Nova S more. Media Center has worked well before.

    Media Library will recognize the new card, search and branch on 239 satellite channels, but may not display the channels giving the error message "there is currently no TV signal detected for this channel. The channel may be temporarily off the air. »

    I have installed WinTV 7 and that you can view all the channels very well in this program so obviously the map and the intensity of the signal are not the problem.

    In my quest through other forums, I heard problems re codec: mpeg2 and we tried several packs of codecs (including shark007) but with no improvement.

    My last move was to uninstall Media Center, uninstall all codec packs, uninstall the TV card and drivers, then reinstall the media library and the TV card and am still unable to view TV channels.

    Suggestions have greatly accepted.

    I've searched the Internet high and low for a solution to this problem and can lead to nothing more than what is proposed here by Divya.

    The problem seems to be fairly common and seems to be associated with codec. Most of the solutions I've come across related to the installation of media center alternatives and after several tries I finally opted for new version of Media Portal 1.1.0 beta

    Installed without a hitch and so far the interface is similar to the media library but has better customization and the ability to incorporate plug-ins.

    I did try the latest version (1.0.2) of the media portal, but said she had a few problems of stability (probably related to the W7 compatibility).

    Very happy now with Media Portal 1.1.0 Beta so will not need any other solution to this problem.
