Represent the real time localization and RFID

Dear java friends
Im student and I’m developing a RFID project using an active tags. My objective in this work is to represent the real time localization of the tags inside a specific plan by calculate the TDoA. Was easy the right the formula however I had hard time to create the plan and I don’t know what way I have to take. I m asking how can I represent my coordinate inside a real plan related to some area like house or factory for example. Can I use some cartography API as GEOTOOLS because they have the same principals? Can I convert the same principals used with the GPS mapping in the RFID plan representation?

Is there in fact anything to localise at all in the data the reader receives from the RFID chip?RFID is passive. The information is static. So location information would need to be produced from the reader.true. But I question the assumption that the information the reader receives from the RFID is in fact of a nature that requires localisation.
It'll almost certainly be data that can do no more than facilitate a database lookup in order to retrieve the actual data (which may be of a nature that allows localisation of course).
But that's not the reader's job. The RFID reader just reads the RFID and passes the data it retrieves to a processing application.
It's just an interface, and should be kept as stupid as possible.
That application can have a need to localise whatever results from processing the data it gets from the reader (or more likely pass it on to some other system for displaying it to an end user, and only at that stage is localisation called for).
For example, a reader might read a pallet number in a warehouse, and send it to the central processing system to look up the pallet content.
This cargo manifest is then displayed on a palmtop computer belonging to the person using the reader.
The reader itself does not need to know whether the palmtop needs to show English, Russian, or Japanese, neither does the backend database.
Instead the manifest is a series of product codes (and number of items/volume indications) which the user interface application uses to request localised product names from the product database.

  • VI Server in the real time target and Vi client under the local computer

    Hi,
       In my project i want to make a data communication between a vi server which is runnig in the real time target and a vi client runs under the local computer (My Computer target).
    My problem is when i Click the property terminal of the property node function (located on the Functions>>All Functions>>
    Application Control palette) , i don't find the front panel open option from the shortcut menu.
    Thanks.

    The Front Panel options are methods.  Try dropping an Invoke Node down instead of a Property Node.

  • How to programmatically set the real-time CVI startup DLL?

    Dear NI Support Engineer:
    I'm part of a team of software engineers working on a real-time aerospace app at Honeywell (Coon Rapids, MN campus).  We're using LabWindows/CVI 9.0 and three LabView 8.6 real-time modules.
    Up until now, we've been using the CVI debugger to launch our real-time apps or just copying the app DLL to C:\ni-rt\cvi on the real-time box and setting it as the default startup DLL.
    What we need to do now is create our own directory structure at the root of C: on the real-time box (which, by the way, is using the Reliant file system).
    In fact, we have created directory ug7500 at the root of C: on the realtime box, and two subdirectories (one for data and one for results) directly under directory ug7500.  We'd like to place all of our app DLLs in the ug7500 directory and have the ability to change the default startup DLL programmatically.
    We've been using your LabWindows/CVI Real-time File Copy Utility to set the startup DLL whenever we're not using the debugger.  That was just fine for the first stage of our development.
    At this stage, however, we need be able to set the startup DLL programmatically.  We have not been able to find out how to do this from reading the real-time module documentation.
    Can you either point us at some documentation on programmatically setting the default startup DLL, or e-mail us the instructions, or give us a phone call and explain what steps we must take.
    Thank you very much.

    Hello All,
    For the reference of anyone else trying to do this, you can modify the INI file to change the startup DLL. Using the INI instrument that ships with CVI (C:\Program Files\National Instruments\CVI90\toolslib\toolbox), you can find the StartupDLLs tag and replace the last value with your startup DLL, such as:
    #include "inifile.h"
    #include <cvirte.h>
    static int status;
    static IniText myINIFile;
    int main (int argc, char *argv[])
     if (InitCVIRTE (0, argv, 0) == 0)
      return -1;    /* out of memory */
     myINIFile = Ini_New (0);
     status = Ini_ReadFromFile (myINIFile, "c:\\ni-rt.ini");
     status = Ini_PutRawString (myINIFile, "LVRT", "StartupDLLs", "c:\\NI-RT\\system\\cvi_lvrt.dll;c:\\ni-rt\\system\\nidevldp.dll;nisysapirpc.dll;niorbp.dll;c:\\ni-rt\\system\\mxsemb.dll;c:\\ni-rt\\system\\nipxism.dll;c:\\NI-RT\\cvi\\myStartup.dll;");
     status = Ini_WriteToFile (myINIFile, "c:\\ni-rt.ini");
     return 0;
    Right now, there are some caveates with using CVI 9.0 to manipulate an INI file to be used on an RT target. The INI functions currently add line breaks automatically for large tag values and adds quotes around the values. For many INI files this is ok (such as TestStand INI files), but it will not work on an RT target. To remove these features, modify the following lines of the inifile.c file located in the same directory as the INI instrument:
    1. On line 38, change the default value of INI_NUM_CHARS_PER_LINE from 80 to a large number such as 8000.
    2. Comment out line 953 (newEntry->addMarkerQuotes = addMarkerQuotes;
    Now you should be able to programmatically change the INI file of your target machine and, therefore, change the startup DLLs.

  • Is there a way to create dependency on the real-time jobs

    Hi,
    We have around 80 real-time services running and loading the changed data into the target.
    The process being used is
    IBM Informix > IBM CDC > JMS (xml messages) > DS real-time services > Oracle EDW.
    While using the above process,  when ever there is change in the fact table and the dimension table, both the real-time services are loading the data at the same time into the target. This is causing issues in looking up data with the timing issue.
    Is there a way where we can create a dependency and resolve the timing issue and make sure the lookup table is loaded and then the master table is loaded?
    Please let me know.
    Thanks,
    C

    Hello
    With the design you curently have, you will have potential sequencing issues.  There is no magic in Data Services to solve this.
    You might want to consider building more complex real-time jobs that accept more complex data structures and have logic to process the data in dependency order.

  • Receiving the error message while executing the Real Time DTP

    Hi,
    I am receiving the error message while executing the Real time DTP for Billing data.
    Error Message - Record filtered in advance as error records with the same key exist     RSM2     722
    When I check the logs below is the message I am able to see. Can someone suggest as how to proceed further.
    Diagnosis
    The existing DTP requires a serialized update because fields are updated
    non-commutatively during the processing run (for example, MOVE).
    Therefore all new data records that have the same semantic key as
    incorrect records that have not yet been corrected in earlier requests
    or earlier data packages of the same request, are filtered out after the
    extraction in a special step. In this way the system ensures that
    incorrect data records are not repeated for your changes, which may not
    contain errors themselves.
    System Response
    The data record is not updated but is written to an error stack.
    Procedure
    Procedure
    Correct all incorrect data records and update them using an error DTP.
    Procedure for System Administration
    I checked the error stack and corrected the entries and let me know as how to proceed further. I am unable to execute the Error DTP as its not allowing me to edit and has only display options.

    The software versions of the NI products (MAX/My System/Software) between my LTH and the iPC are
    almost the same. The only differences are:
    1. LabView Run-Time 2009 SP1 (64-bit); is installed on LTH but missing on iPC. The iPC has a 32-bit system.
    2. LabView Run-Time 2012 f3; is installed on LTH but missing on iPC.
    3. NI-DAQmx ADE Support 9.3.5; something strage on the LTH, because normally I am using NI-DAQmx 9.5.5 and all other DAQmx products on my LTH are 9.5.5. That means NI-DAQmx Device Driver 9.5.5 and NI-DAQmx Configuration 9.5.5.. On the iPC side all three products are 9.5.5.. That means NI-DAQmx ADE Support 9.5.5, NI-DAQmx Device Driver 9.5.5 and NI-DAQmx Configuration 9.5.5..

    Hi Lukas,
    I think the problem is caused by differenet drivers for the CAN communication.
    NI provides two driver for CAN: NI-CAN and NI-XNET.
    NI-CAN is the outdated driver which is not longer used by new hardware. NI replaced the NI-CAN driver with NI-XNET some years ago, which supports CAN, LIN and the FLEXRAY communication protocol.
    You wrote:

    NI CAN is the outdated driver. I think that you should try to install NI-XNET instead of NI-CAN on your PXI-System, to get rid of the error message.

  • BT NetProtect plus – Real time scanning and update...

    I have posted this message as both a pointer in case others have the same issue as well as whether anyone has found a proper resolution.
    I have recently experianced problems with my BT NetProtect plus indicating the Real time scanning has stopped and any attempt to restart it does not work. This is accompanied with it keep promptig that there is a new update and to restart the computer. This happened every time I logged on.
    I had spent some considerable time with the BT support people who have now reinstalled the software about 6 time's after the 2 time I had already tried.
    I run Windows 7 64 bit and recently installed an SSD drive. The key thing I have subsequently discovered in my upgrade is that I changed some registry settings to make my default installation location to be my D: drive. I followed this post :
    The 64bit version has two versions of regedit. Make this change as well:
    1.) Enter into Start>Run: %systemroot%\syswow64\regedit 2.) Go to: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion 3.) Change the Path in DWORDs ProgramFilesDir, ProgramFilesDir (x86) to the new path, probably just changing the drive letter
    Everything works fine apart from BT NetProtect plus which when installed new has the above issue.  If I change the default install location back to C: drive then it installs OK and works OK when I subsequently change the default install location back to the D: drive. When I say works OK, that is until BT NetProtect plus issues a major update when the same problem appears again.
    I am waiting further contact from the 3rd line helpdesk but the 2nd line team did not seam to know of this problem.
    Has anyone else experenced it or know of a proper solution ?

    A full McAfee scan on my desktop PC can take about 2 hours or so and a full scan sometimes slows down my over 3 year old desktop PC. Thats why I only do a full McAfee scan every once in a while but I do a quick McAfee scan every 6 or 7 days.
    I do like the McAfee shredder though and use that now and again. I also got McAfee quick clean set to run at lest twice a week.  
    I have used Norton in the past and that slowed down my last PC more than McAfee from BT. The free version of AVG is good but its only an anti-virus. Some say the windows firewall is ok but not the best.
    I also have windows defender set to do a quick scan every evening around 9pm. As most nights I have my Desktop PC on at that time.
    I also do a disk clean up at leat once a day.

  • Can we use the AdventureWorks2008R2 data for the real time project.

    Hi,
    In our project we are trying to do the data scrambling on First name, last name and middle name...
    In the regular practice we use to update the names as
    First Name = FN+<PERSON_SNO>
    Last Name = LN+<PERSON_SNO>
    Middle Name = MN+<PERSON_SNO>
    The Problem is the names are not looking realistic, so I thought of applying some logic and updating our PERSON table names based on Person.Person table in adventure works.
    My question is can we use the AdventureWorks2008R2 data for the real time project. Is there any cop right issue.
    Someone please help me solve this issue.

  • BAdI........How are they used in the real time scenario.

    Im a rookie in ABAP development and i was wondering that how we use the BAdI enhancement technique in the real time scenarios. Like do we get create them or we have few already built BAdI's which we work on? Can any body please explain how this works.

    Hi Ramana,
    Business add-ins are enhancements to the standard version of the system.
    Business Add-In is a new SAP enhancement technique based on ABAP Objects.
    They can be inserted into the SAP system based on specific user requirements.
    Each Business Add-In has:
    • at least one Business Add-In definition
    • a Business Add-In interface
    • a Business Add-In class that implements the interface
    In order to enhance a program, a Business Add-In must first be defined
    Subsequently two classes are automatically generated:
    • An interface with ‘IF_EX_’ inserted between the first and second characters of the BADI name.
    • An adapter class with ‘CL_EX_’ inserted between the first and second characters of the BADI name.
    The Application developer creates an interface for this Add-In.
    There are multiple ways of searching for BADI.
    • Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
    • Finding BADI Using SQL Trace (TCODE-ST05).
    • Finding BADI Using Repository Information System (TCODE- SE84).
    1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for ‘CL_EXITHANDLER=>GET_INSTANCE’.
    Make sure the radio button “In main program” is checked. A list of all the programs with call to the BADI’s will be listed.
    The export parameter ‘EXIT_NAME’ for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter ‘INSTANCE’ will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
    2. Start transaction ST05 (Performance Analysis).
    Set flag field "Buffer trace"
    Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)
    Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.
    Push the button "Deactivate Trace".
    Push the button "Display Trace".
    The popup screen "Set Restrictions for Displaying Trace" appears.
    Now, filter the trace on Objects:
    • V_EXT_IMP
    • V_EXT_ACT
    Push button "Multiple selections" button behind field Objects
    Fill: V_EXT_IMP and V_EXT_ACT
    All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.
    So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA
    3. Go to “Maintain Transaction” (TCODE- SE93).
    Enter the Transaction VD02 for which you want to find BADI.
    Click on the Display push buttons.
    Get the Package Name. (Package VS in this case)
    Go to TCode: SE84->Enhancements->Business Add-inns->Definition
    Enter the Package Name and Execute.
    Here you get a list of all the Enhancement BADI’s for the given package MB.

  • How can I save/write data on the hard disc of the Real-Time System?

    I would like to acquire huge size of data via LabView Real-Time System.
    Since data is so huge, I am now thinking that it might be good idea to
    write/save data on the hard disc of the Real-Time System first and then
    transfer the data file to a data processing PC using FTP etc.
    If you know how to save/write data on the hard disc of the Real-Time System
    (Ver. 7.1), please let me know.
    Thanks,

    Just to add to Aitortxo's good answer,
    Since you have only one Drive ( C:\) on your RT, just keep monitering the availible disc space.
    After every few set of file writes keep transferring Backups delete these files, so that you  keep C:\ drive space for running your applications.

  • How to plot cross-corr​elation in terms of the real time?

    Usually the cross-correlation or the auto-correlation results are plotted vs. the lag(tao). But how can I plot it vs. the real time of the input signal? I have two same length input signals having same input time.

    I am using LabView 7Express. What I use is the "convolution and correlation" VI, without the 'Express' however ... I mean, if both my input signals are L-length, the result of the correlation will be 2L-length, i.e. the length is doubled. But I want to keep the original signal size, making the result L-length as well, and have the same time origin as the input signals. I mean, if my input signals are from 0-1 second, I also expect to see the cross-correlaton is within 0-1 second, having the same data points. Thanks a lot!
