Description
Mobiler Datenträger bzw. Schreib-Lese-Gerät mit einer Antennenanordnung mit einstellbarer Charakteristik, und dazugehörige Transportvorrichtungmobile disk or read-write device with an antenna arrangement with adjustable characteristics, and associated transport device
Die Erfindung bezieht sich auf einen mobilen Datenträger mit einer Antennenanordnung zum berührungslosen Austausch von Daten. Die Erfindung bezieht sich ebenfalls auf ein Schreib-Lese-Gerät mit einer Antennenanordnung zum berührungslosen Austausch von Daten, insbesondere mit einem mobilen Datenträger. Die Erfindung bezieht sich schließlich auf eine Transportvorrichtung für Güter mit zumindest einem mobilen Datenträger bzw. zumindest einem Schreib-Lese-Gerät.The The invention relates to a mobile data carrier with an antenna arrangement for contactless Exchange of data. The invention also relates to a Read-write device with a Antenna arrangement for contactless exchange of data, in particular with a mobile data carrier. The The invention finally relates on a transport device for Goods with at least one mobile data carrier or at least a read-write device.
Mobile Datenträger und Schreib-Lese-Geräte werden insbesondere bei Identsystemen eingesetzt. Diese können vorteilhaft z.B. zur Verfolgung von Waren- und Güterströmen verwendet werden. So können beispielsweise in einer Fertigungsanlage für Kraftfahrzeuge die durchlaufenden Rohkarosserien mit mobilen Datenträgern versehen werden. Dabei wird z.B. vor dem Einlauf einer Rohkarosse in eine einzelne Fertigungsstation der aktuelle Inhalt des zugeordneten mobilen Datenträgers von einem dort platzierten Schreib-Lese-Gerät auf berührungslose Weise gelesen. Hierdurch ist es z.B. möglich, individuelle und ausschließlich die jeweils anstehende Rohkarosse betreffende Bearbeitungsvorgänge durchzuführen. Nach Abschluss dieser Bearbeitungsvorgänge wird der Dateninhalt des zugeordneten mobilen Datenträgers durch das lokale Schreib-Lese-Gerät aktualisiert und die Rohkarosse wird zu einer weiteren Fertigungsstation transportiert. Nun ist es möglich, den Dateninhalt des zugeordneten mobilen Datenträgers vor der anderen Fertigungsstation durch das dort platzierte Schreib-Lese-Gerät erneut zu Lesen. Es können der aktuelle Bearbeitungszustand und die nun anstehenden, gegebenenfalls vom Typ der jeweiligen Karosse abhängigen Bearbeitungsschritte erkannt und ausgeführt werden.mobile disk and read-write devices are used in particular for identification systems. These can be beneficial e.g. used to track goods and goods flows. So, for example in a manufacturing plant for Motor vehicles provided the running bodies with mobile data carriers become. In doing so, e.g. before the entry of a body shell into a single manufacturing station the current content of the assigned mobile data carrier read by a read-write device placed there in a non-contact manner. hereby it is e.g. possible, individual and exclusive to carry out the respective pending bodywork operations. To Completion of these editing operations will be the data content of the associated mobile data carrier updated by the local read-write device and the body shell is transported to another manufacturing station. Now it is possible the Data content of the assigned mobile data carrier in front of the other production station read again by the read / write device placed there. It can the current processing status and now pending, if necessary Depending on the type of the respective body dependent processing steps be recognized and executed.
Bei einem anderen, beispielhaften Einsatz eines Identsystems sind Stückgüter, z.B. Pakete, Gepäckstücke, Transporteinheiten für Rohkarosserien und vieles mehr, jeweils mit einem mobilen Datenträger versehen. Darin können Daten gespeichert sein, welche z.B. die Art und das Transportziel des jeweiligen Stückgutes beschreiben. Durchlaufen derartige Stückgüter z.B. eine Verteilungsanlage, so können diese Daten an bestimmten Stellen der Anlage von dort platzierten Schreib-Lese-Geräten erfasst werden. Nun ist es möglich einzelne Transportvorrichtungen in der Verteilungsanlage, z.B. Förderbänder, geeignet zu steuern. Das jeweilige Stückgut kann nun so vereinzelt werden, dass es das gewünschte Transportziel innerhalb der Verteilanlage erreicht oder unter Zuhilfenahme von zwischengeschalteten, weiteren Transportmitteln, wie z.B. Fahrzeugen, erreichen kann.at In another exemplary use of an identifier system, piece goods, e.g. Packages, luggage, transport units for body shells and much more, each with a mobile disk provided. It can contain data stored, which e.g. the type and destination of the respective piece goods describe. Passing through such cargo, e.g. a distribution system, so can these Data collected at certain points of the system from there placed read-write devices become. Now it is possible individual transport devices in the distribution system, e.g. Conveyor belts, suitable to control. The respective piece goods can now be singulated so that it is the desired transport destination within the distribution system reached or with the help of intermediate, further Means of transport, such as Vehicles, can reach.
In der Regel durchlaufen Waren und Güter, die mit berührungslos lesbaren mobilen Datenträgern ausgerüstet sind, eine der obigen Anlagen mit möglichst hoher Geschwindigkeit. Um einen in jedem Falle fehlerfreien Datenaustausch mit den an ausgewählten Stellen der Anlage platzierten Schreib-Lese-Geräten zu gewährleisten, dürfen zumindest die maximal zulässigen Abstände zwischen den eingesetzten mobilen Datenspeichern und den dazugehörigen Schreib-Lese-Geräten nicht überschritten werden. Diese Abstände sind insbesondere abhängig von dem zwischen den mobilen Datenspeichern und Schreib-Lese-Geräten eines Systems verwendeten Übertragungsprinzip und den jeweils eingesetzten Sendeleistungen. Beruht die Übertragungsstrecke z.B. auf einer Funkübertragung, so wird der maximal zulässige Abstand auch durch das für die Datenübertragung eingesetzte Frequenzband bestimmt. Besondere Anforderungen liegen bei passiven mobilen Datenspeichern vor. Diese verfügen über keine eigene Energieversorgung, sondern werden ausschließlich über die Sendeenergie eines Schreib-Lese-Gerätes gespeist.In usually go through goods and goods with contactless readable mobile data carriers are equipped, one of the above systems with as possible high speed. In any case, error-free data exchange with those at selected At least places to ensure the placement of read-write devices are allowed the maximum allowable distances between the mobile data memories used and the associated read-write devices become. These distances are particularly dependent on between the mobile data memories and read-write devices of a Systems used transmission principle and the transmission power used in each case. If the transmission path is based, e.g. on a radio transmission, so will the maximum allowable Distance also by that for the data transmission used frequency band determined. Special requirements are in passive mobile data storage. These do not have any own energy supply, but are exclusively on the Transmitted energy of a read-write device.
Bei der Projektierung eines Identsystems ist somit zumindest darauf zu achten, dass die maximal zulässigen Abstände zwi schen den mobilen Datenspeichern und den Schreib-Lese-Geräten des Systems nicht überschritten werden. Vielfach sind aber weitere Maßnahmen erforderlich, um die Übertragungsverhältnisse zwischen den entlang einer Transportvorrichtung verteilt angebrachten Schreib-Lese-Geräten und den auf der Transportvorrichtung gemeinsam mit Transportgütern daran vorbei geförderten mobilen Datenspeichern zu optimieren. So können die Übertragungsverhältnisse für jedes einzelne Schreib-Lese-Gerät z.B. durch eine mittels manueller Justage optimierte Platzierung am Rande der Transportvorrichtung verbessert werden. Dies ist aber sehr aufwendig und nicht immer möglich, insbesondere bei Vorliegen von schwierigen Anbaubedingungen in Inneren eines komplexen Verteilungssystems oder einer Fertigungsanlage.at the configuration of an Identsystems is thus at least on it to pay attention to the maximum allowable distances between the mobile data memories and the read-write devices of the System not exceeded become. In many cases, however, further measures are required to control the transmission conditions between the distributed distributed along a transport device Read-write devices and on the transport device along with transport goods on it sponsored by optimize mobile data storage. So can the transmission conditions for each single read / write device e.g. by an optimized by manual adjustment placement on the edge of Transport device can be improved. This is very expensive and not always possible especially in the presence of difficult growing conditions in the interior a complex distribution system or a manufacturing plant.
Es ist deshalb die Aufgabe der vorliegenden Erfindung, einen mobilen Datenträger und/oder ein Schreib-Lese-Gerät anzugeben, womit eine anwendungsabhängige Optimierung von Übertragungsverhältnissen auf eine einfachere Weise möglich ist.It is therefore the object of the present invention, a mobile disk and / or a read-write device specify what an application-dependent optimization of transmission ratios in a simpler way possible is.
Die Aufgabe wird gelöst durch den im Anspruch 1 angegebenen mobilen Datenträger. Dieser weist eine Antennenanordnung zum berührungslosen Austausch von Daten insbesondere mit einem Schreib-Lese-Gerät auf. Erfindungsgemäß sind Mittel zur Einstellung einer ausgewählten Charakteristik der Antennenanordnung des mobilen Datenträgers vorhanden.The object is achieved by the mobile data carrier specified in claim 1. This has an antenna arrangement for the contactless exchange of data, in particular with a read-write device. According to the invention Mit tel for setting a selected characteristic of the antenna arrangement of the mobile data carrier present.
Die Aufgabe wird weiterhin gelöst durch das in Anspruch 6 angegebene Schreib-Lese-Gerät. Dieses weist ebenfalls eine Antennenanordnung zum berührungslosen Austausch von Daten insbesondere mit einem mobilen Datenträger auf. Erfindungsgemäß sind auch hier Mittel zur Einstellung einer ausgewählten Charakteristik der Antennenanordnung des Schreib-Lese-Geräts vorhanden.The Task is still solved by the write-read device specified in claim 6. This also has an antenna arrangement for the contactless exchange of data especially with a mobile disk. Also according to the invention here means for setting a selected characteristic of the antenna arrangement of Read-write device available.
Der Vorteil der Erfindung liegt darin, dass für alle z.B. in einem Identsystem eingesetzten mobilen Datenträger die Cha rakteristik der Antennenanordnung optimal voreingestellt werden kann. Bevorzugt kann diese Einstellung bei allen verfügbaren mobilen Datenträgern einheitlich z.B. in einem Konfektionierungs- oder Maschineneinrichtungsbereich vorgenommen werden. Es sind also keine Eingriffe im laufenden Betrieb einer Anlage mehr notwendig. Dies trifft besonders auch auf die Schreib-Lese-Geräte eines Identsystems zu. Auch die Charakteristik von deren Antennenanordnung kann abhängig von den in der jeweiligen Anlage vorliegenden Bedingungen mit Hilfe der Erfindung optimal eingestellt werden, bevor die Schreib-Lese-Geräte einer Anlage im Feld platziert und dort in Betrieb genommen werden.Of the Advantage of the invention is that for all e.g. in an Identsystem used mobile data carrier the cha characteristics of the antenna array optimally pre-set can be. Preferably, this setting can be uniform for all available mobile data carriers e.g. in a packaging or machine equipment area be made. So there are no interferences during operation a plant more necessary. This applies especially to the Read-write device an Identsystems too. Also the characteristic of their antenna arrangement can be dependent from the conditions given in the respective annex with the help of the invention be optimally adjusted before the read-write devices of a Plant placed in the field and put into operation there.
Gemäß der Erfindung ist es bei einem mobilen Datenträger bzw. bei einem Schreib-Lese-Gerät besonders vorteilhaft, wenn die Mittel die Charakteristik so einstellen, dass die jeweilige Antennenanordnung ein Richtdiagramm mit zumindest einem Intensitätsmaximum der Empfangsfeldstärke aufweist. Diese Intensitätsmaxima können insbesondere bei den mobilen Datenträgern dann so eingestellt werden, dass die Richtdiagramme auf die am Rande z.B. einer Transportvorrichtung platzierten Schreib-Lese-Geräte fokussiert sind.According to the invention it is with a mobile data carrier or in a read-write device especially advantageous if the means set the characteristic so that the respective antenna arrangement is a directional diagram with at least an intensity maximum the reception field strength having. These intensity maxima can especially when the mobile disks are set so that the directional diagrams on the marginal e.g. a transport device placed read-write devices are focused.
Besonders vorteilhaft können dann die Intensitätsmaxima der Richtdiagramme bei den mobilen Datenträgern bzw. bei den Schreib-Lese-Geräten in Richtung zu einer Hauptachse der Antennenanordnung verlaufen. Falls bei dieser Einstellung die mobilen Datenträger z.B. auf metallischen Gestellen montiert sind, welche als Transporteinheiten für Güter von einer Transporteinheit fortbewegt werden, so weist in diesem Fall das Richtdiagramm der Antenne eine nach vorne gerichtete keulenförmige Charakteristik auf. Es tritt also bei jedem mobilen Datenträger ein vorteilhaft in Bewegungsrichtung oder auf eine Seite der Transporteinheit orientiertes Intensitätsmaximum der Empfangsfeldstärke auf. Hiermit ist es besonders dann, wenn die Schreib-Lese-Geräte eines Identsystems alle einheitlich auf einer bestimmten Seite der Transporteinheit platziert sind, möglich, diese mit den Empfangsfeldstärkekeulen der mobilen Datenträger eindeutig zu überdecken. Es sind dann optimale Bedingungen für eine möglichst störungsfreie Datenübertragung zwischen den mobilen Datenträgern und den Schreib-Lese-Geräten selbst bei einem schnell laufenden System eingestellt.Especially can be advantageous then the intensity maxima the directional diagrams in the mobile data carriers or in the read / write devices in the direction extend to a main axis of the antenna arrangement. If at this Setting the mobile disks e.g. mounted on metal racks which act as transport units for goods of one Transport unit to be moved, so in this case, the Directional diagram of the antenna on a forward-facing club-shaped characteristic. It thus occurs in each mobile disk advantageous in the direction of movement or on one side of the transport unit oriented intensity maximum of Reception field strength on. This is especially true when the read-write devices of a Identsystems all placed uniformly on a particular side of the transport unit are possible, these with the reception field strength lobes the mobile disk unique to cover. It is then optimal conditions for the most trouble-free data transmission between the mobile disks and the read-write devices even set in a fast running system.
Bei einer anderen Ausführung können die Intensitätsmaxima der Richtdiagramme bei den mobilen Datenträgern bzw. bei den Schreib-Lese-Geräten auch so eingestellt werden, dass diese orthogonal zu einer Hauptachse der Antennenanordnung verlaufen. Falls auch bei dieser Einstellung die mobilen Datenträger z.B. auf metallischen Gestellen montiert sind, welche als Transporteinheiten die Güter in einer Transportvorrichtung fortbewegen, so tritt in diesem Fall bei jedem mobilen Datenträger in Bewegungsrichtung eine auf beide Seiten der Transporteinheit orientierte doppelkeulenförmige Charakteristik auf. Die Richtdiagramme weisen somit zwei, nach rechts und links abgewinkelte Intensitätsmaxima der Empfangsfeldstärke auf. Diese Anordnung ist besonders vorteilhaft, wenn die Schreib-Lese-Geräte eines Identsystems wechselseitig auf der einen und der anderen Seite der Transportvorrichtung platziert sind. Hiermit ist es möglich sicherzustellen, dass die darauf geförderten Transporteinheiten mit der rechtsseitigen oder linksseitigen „Teilkeule" der Empfangsfeldstärke eindeutig zu überdeckt werden. Es sind somit auch in diesem Falle optimale Bedingungen für eine möglichst störungsfreie Datenübertragung zwischen den mobilen Datenträgern und den Schreib-Lese- Geräten selbst bei einem schnell laufenden System eingestellt.at another version can the intensity maxima the directional diagrams in the mobile data carriers or in the read-write devices also be set to be orthogonal to a major axis the antenna arrangement run. If also with this attitude the mobile data carriers e.g. mounted on metal racks which act as transport units the goods move in a transport device, so occurs in this case with every mobile data carrier in the direction of movement oriented on both sides of the transport unit double lobar Characteristic. The directional diagrams thus have two, to the right and left angled intensity maxima the reception field strength on. This arrangement is particularly advantageous when the read-write devices of a Identsystems alternately on one and the other side of the transport device are placed. Hereby it is possible ensure that the transport units promoted thereon clearly overlapped with the right-sided or left-side "partial lobe" of the reception field strength become. There are thus also in this case optimal conditions for as possible trouble-free data transfer between the mobile disks and the read-write devices even set in a fast running system.
Vorteilhaft sind die Mittel zur Einstellung einer ausgewählten Charakteristik der Antennenanordnung in Form einer Phasenschieberschaltung ausgeführt.Advantageous are the means for adjusting a selected characteristic of the antenna arrangement executed in the form of a phase shifter circuit.
