Conversion accélération vitesse et déplacement

Boujours à tous,
je viens vers vous, car comme le titre l'indique je dispose d'un accéléromètre qui renvoie un signal en v ( 120mv /g) . Je souhaite à l'aide de mon entrée analogique qui receptionne la valeur de mon accélération obtenir le déplacement et la vitesse. Je sais que je dois réaliser une double intégration. Je veux également réaliser une acquisition continue de l'acc déplacement et vitesse... Cependant jusqu'à présent et malgrés de nombreux exemples que j'ai pu observer je ne trouve pas chaussure à mon pied. Il semblerait que je mesure un bruit assez important, je songeais surement à réaliser une autocorrélation...
ci-joint mon Vi . Quelqu'un peut-il me dépanner ou me transmettre un exemple de Vi correspondant à mon application . car je ne trouve que des exemples "théoriques".
Cordialement

Bonjour emmamto,
Voici un diagramme qui réalise le calcul que tu souhaite (si je ne me suis pas trompé ;-)
Concernant ta seconde question je ne suis pas certain de bien la comprendre... si le tension vient d'un capteur tu devrai trouver dans la doc la relation entre les deux qui est en général un relation du type ax+b. Pour implémenter cela en LabVIEW tu peux utiliser les fonctions de la palette Numérique
PS: Je crois que ce forum est trés similaire

  • Erreur de calcul amplitude FFT à f = 0Hz

    Avec l'objet sousMesuresSpectrales [subSpectralMeasurements.vi] de la librairie LabView, sous LabVIEW7.1\vi.llb\express\express analysis\SpectralBlock.llb, je constate un problème de calcul sur la FFT pour fréquence = 0 Hz en amplitude.
    Dans mon application, j'ai exporté ce VI express pour n'utiliser que certaines de ses fonctionnalités, en autres propriétés : "Paramètres du signal" pour afficher sa FFT.
    Normalement, à la fréquence = 0Hz, l'amplitude max et efficace doivent être identiques et correspondre à la composante continue i.e DC value. Ce résultat n'est pas observé. J'observe le rapport racine de 2 habituel pour une valeur pic ou RMS à f = 0Hz.

  • Mon ipod s'arrete au bout de quelques secondes de lecture, avec la mise en veille de l'ecran. que faire pour que la musique continue?

    Bonjour,
    J'ai changé d'ipod à Noel, et j'ai reçu comme cadeau le nouvel ipod nano 6è generation.
    Il fonctionnait trés bien jusque hier quand il s'est mis à s'arrêter au bout de quelques secondes avec la mise en veille de l'écran!
    Que faut-il faire pour que mon ipod fasse ce que j'en attends : lire de la musique en continu?
    Merci de m'aider car je ne sais pas quoi faire!
    J'ai déjà essayé les commandes de réglage de la veille, sans véritable succès!
    J'ai réinstallé le logiciel sur itune, restauré puis synchronisé, aucune évolution...
    Rien n'y fait, je suis bloqué avec cette panne!
    D'avance, merci!

  • Problème accélèromètre et toolkit sound and vibrations

    Bonjour,
    Je viens vers vous car je cherche à mesurer une accélération. Et, à l'aide celle-ci obtenir la valeur de mon déplacement et de ma vitesse . Je précise que l'application est utile pour un pot vibrant. Cependant "l'ensemble" des Vi que j'ai pu observé jusqu'à présent utilise l'option supplémentaire de labview : Sound and vibration toolkit.
    on accéléromètre est un piézoélectrique ( voir doc ci joint) et je voulais savoir quelle la solution la plus évidente et la plus précise à utiliser sans pour autant acheter le toolkit sound and vibration. Je précise que le boitier que j'utilise est un boitier NI USB 6353.
    Merci d'avance.

    Bonjour Geoff54,
    Effectivement, une fois l'accélération acquise, il faut que vous fassiez des calculs mathématiques pour récupérer la vitesse et le déplacement. Vous trouverez les formules ici: http://fr.wikipedia.org/wiki/Acc%C3%A9l%C3%A9ration#Math.C3.A9matiquement

  • Attachment of original message in file sender adapter content conversion

    Hi,
    does anybody know how I can configure a file sender communication channel (with content conversion) so that the original file is added to the XI SOAP message as attachment? Maybe this is just a parameter in "Advanced" tab. (The content conversion itself is not an issue.)
    The result should be the "Main Document" (XML-message) and the "original document" as two attachments in the SOAP payload.
    The reason for this is that the original file should be archived with the XML message as it was before the XML content conversion of the file sender adapter took place.
    Thanks,
    Philipp

    original file is added to the XI SOAP message as attachment?
    The "Advanced" tab -> additional files added in file adapter should act as the attachment to soap receiver adapter if u select the "Keep Attachments" option in soap receiver communication channel.
    What do u want to do in FCC is a bit unclear?

  • What is use of  Conversion Routine in  Abap dictionary

    Hi,
    Can any body please tell me the proper use of <b>Conversion Routine in  Abap dictionary.</b>
    Please give me a practical example where it has been used.
    Thanks
    prabhudutta

    hi,
    here is help for conversion routine
    Conversion takes place when converting the contents of a screen field from display format to SAP-internal format and vice versa and when outputting with the ABAP statement WRITE, depending on the data type of the field.
    If standard conversion is not suitable, it can be overridden by specifying a conversion routine in the underlying domain.
    A conversion routine is identified by its five-place name and is stored as a group of two function modules. The function modules have a fixed naming convention. The following function modules are assigned to conversion routine xxxxx:
    CONVERSION_EXIT_xxxxx_INPUT
    CONVERSION_EXIT_xxxxx_OUTPUT
    The INPUT module performs the conversion from display format to internal format. The OUTPUT module performs the conversion from internal format to display format.
    If a screen field refers to a domain with a conversion routine, this conversion routine is executed automatically each time an entry is made in this screen field or when values are displayed with this screen field.

  • Transport Issue - no conversion of source system name

    Hi Everyone,
    I've experienced the same problem on a BW 7.01 system on Support Pack 6.  I was able to solve it through implementing the following notes:
    - 1412414 (SP24) Content is not generated/transport errors; and
    - 1489612 Objects of the type DTRF deleted after method is executed (supplemental note to 1412414)
    See my reply on the below message for further details:
    Re: Source RSDS DS_CA_CLIFID DBW_150 does not exist
    I hope you found this useful as 'solved with workaround' wasn't particularly helpful to me.

  • What is conversion routine which is found in data element

    Hi all,
    I was just trying to creating a data element assigned to a particular domain in se11. While i am creating i can see a conversion routine
    Can anyone tell me what is the use of that conversion routine with an example.
    thanxs in advance
    hari

    Hi,
    Depending on the data type of the field, there is a conversion when the contents of a screen field are converted from display format to SAP-internal format and vice versa. If this standard conversion is not suitable, it can be overridden by defining a conversion routine in the underlying domain.
    Conversion routines are identified by a five-place name and are stored as a group of two function modules. The function modules have a fixed naming convention. The following function modules are assigned to conversion routine xxxxx:
    CONVERSION_EXIT_xxxxx_INPUT
    CONVERSION_EXIT_xxxxx_OUTPUT
    The INPUT module converts from display format to internal format, and the OUTPUT module converts from internal format to display format.
    When is a Conversion Routine Executed?
    If a screen field refers to a domain with a conversion routine, this conversion routine is executed automatically when entries are saved in this screen field or when values are displayed in this screen field. The conversion routine of the domain is also triggered when the field contents are output with the WRITE statement.
    Table SPFLI in the  flight model contains information about the flights offered by the carriers. The time for each flight is recorded in field FLTIME. Enter and display the time of the flight in input templates in the form HHH:MM (hours:minutes). Store the flight time entered in the database as an integer number (number of minutes of the flight). An entry 3:27 is therefore stored in the database as 207 (3 hours, 27 minutes = 207 minutes).
    Field FLTIME refers to domain S_DURA, to which conversion routine SDURA is assigned. The value is thus converted by the two function modules <b>CONVERSION_EXIT_SDURA_INPUT</b> and <b>CONVERSION_EXIT_SDURA_OUTPUT</b>.
    A conversion routine can also be triggered by specifying its five-place name in the attributes of a field in the Screen Painter or with the addition <b>USING EDIT MASK <Name of conversion routine></b> in the WRITE command in the program. With the USING NO EDIT MASK addition in the WRITE statement, you can skip a conversion routine defined for a domain when outputting.
    Parameters
    The two function modules of a conversion routine must have precisely two parameters with the names INPUT and OUTPUT for the value to be converted and the converted value.
    The INPUT parameter in the INPUT conversion and the OUTPUT parameter in the OUTPUT conversion should not have any reference fields because the value passed in the call could have a different length than that expected.
    Programming Conversion Routines
    ABAP statements that result in an interruption of processing (such as CALL SCREEN, CALL DIALOG, CALL TRANSACTION, SUBMIT, COMMIT WORK, ROLLBACK WORK, MESSAGE I, MESSAGE W) are not allowed in conversion routines.
    Only A messages are meaningful in output conversion, but A, E and S messages can be triggered in input conversion (although S messages are not very meaningful here). E messages result in an error dialog. Exceptions are not intercepted in the call.
    The output conversion is also triggered with WRITE and WRITE TO. The conversion routine may therefore occur very frequently with lists. The output conversion should therefore be programmed as efficiently as possible.
    No external performs should be used in conversion routines. Programs that are called externally use the table work areas of the first calling main program. In conversion routines this can result in errors that cannot be easily analyzed since they are sometimes called at unpredictable times in the program flow.
    <b>Pls refer link which contains code as an example to conversion routine used in abap</b>.
    <a href="http://www.bwexpertonline.com/downloads/source_code.doc">http://www.bwexpertonline.com/downloads/source_code.doc</a>

  • Convert float to rational

    Hello,
    The TIFF tag header protocol requires a data type I am not really conversant with, the Rational Data type: http://en.wikipedia.org/wiki/Rational_data_type
    I need to convert double precision numbers to this data type, e.g. 24.5 needs to be a ratio of two integers: {49,2}. Is there an existing LabVIEW algorithm to perform this operation? All my NI searches keep resulting in Rational ClearCase or Rational Array interpolation. I seem to have found a lot of the theory behind this: http://stackoverflow.com/questions/95727/how-to-convert-floats-to-human-readable-fractions
    But, is this implemented in labVIEW already, or should I implement the above-referenced c-code?
    Thanks,

  • Conversion exit ALPHA, external- internal

    What does the below Alpha Conversion do :
    <b>Conversion exit ALPHA, external->internal</b>
    An example wud help me understand better!!

    Hi,
    A conversion routine is identified by its five-place name and is stored as a group of two function modules. The function modules have a fixed naming convention. The following function modules are assigned to conversion routine xxxxx:
    CONVERSION_EXIT_xxxxx_INPUT
    CONVERSION_EXIT_xxxxx_OUTPUT
    The INPUT module performs the conversion from display format to internal format. The OUTPUT module performs the conversion from internal format to display format.
    E.g. If you specify ALPHA conversion for Material number then when user enters the value for MATNR as 123; internally it is converted to 0000123 and is stored in that format in the database. In this case, conversion is done from external format to internal format and the other way if you are reading value from database; it is converted from internal to external format and value is shown as 123, instead of 0000123.
    Hope this helps.
