Description

Die Erfindung betrifft einen Fahrtschreiber mit mindestens einem Kartenleser und einer Druckeinrichtung gemäß dem Oberbegriff des ersten Patentanspruchs.The invention relates to a tachograph with at least one card reader and a printing device according to the preamble of the first claim.

Fahrtschreiber mit mindestens einem Kartenleser und einer Druckeinrichtung sind seit längerem beispielsweise aus dem Dokument DE 35 05 068 C1 bekannt. Es wurden auch bereits Fahrtschreiber vorgeschlagen, die ihre Daten an ein im Fahrzeug befindliches Bordnetz, das als Datenbus betrieben wird, abgeben können. An den bekannt gewordenen Fahrtschreibern ist nachteilig, daß ihre Kommunikationseinrichtungen, wie beispielsweise ein Kartenleser oder eine Druckeinrichtung, nur fahrtschreiberspezifisch eingesetzt werden. So wird herkömmlich der Kartenleser nur zum Lesen und Schreiben von Daten genutzt, die zur Erfüllung der gesetzlichen Aufgaben des Fahrtschreibers gehören. Ebenso wird die Druckeinrichtung seit ihrer Implementierung in einen Fahrtschreiber nur zum Ausdruck von Daten genutzt, die mit den Überwachungsaufgaben eines Fahrtschreibers zu tun haben. Damit dient der Fahrtschreiber ausschließlich Aufgaben im Rahmen eines gesetzlich vorgeschriebenen Kontrollgerätes.Tachograph with at least one card reader and a printing device has long been known, for example, from document DE 35 05 068 C1. It Tachographs have already been proposed, which send their data to an im Vehicle electrical system, which is operated as a data bus, can deliver. A disadvantage of the tachographs that have become known is that their Communication devices, such as a card reader or Pressure device, only be used for the tachograph. So will Conventionally, the card reader is used only for reading and writing data to fulfill the legal tasks of the tachograph. Likewise, the printing device since its implementation in a tachograph only for Printout of data used with the monitoring tasks of a Tachograph have to do So the tachograph serves exclusively Tasks within the scope of a legally prescribed control device.

Es ist nun die Aufgabe der vorliegenden Erfindung, die Funktionalität eines Fahrtschreibers mit einer Schnittstelle für seinen Anschluß an einen Datenbus dahingehend zu erweitern, daß seine Einrichtungen, wie ein Kartenleser und/oder eine Druckeinrichtung, zur Wahrnehmung weiterer Aufgaben zur Verfügung stehen. It is now the object of the present invention, the functionality of a Tachograph with an interface for its connection to a data bus to expand in that its facilities, such as a card reader and / or a printing device for performing other tasks.

Die Aufgabe wird durch die Merkmale des ersten Patentanspruchs gelöst. Die abhängigen Ansprüche zeigen vorteilhafte Ausgestaltungen der vorgeschlagenen Lösung.The object is achieved by the features of the first claim. The dependent claims show advantageous embodiments of the proposed Solution.

Die Lösung ist dadurch gekennzeichnet,

  • daß der Fahrtschreiber mit mindestens einem Kartenleser und einer Druckeinrichtung ausgestattet ist,
  • daß der Fahrtschreiber über eine Schnittstelle für seinen Anschluß an einen Datenbus verfügt,
  • daß von dem mindestens einen Kartenleser gelesene Daten mindestens an eine weitere am Datenbus angeschlossene Vorrichtung übertragbar sind,
  • daß Daten von mindestens einer weiteren am Datenbus angeschlossenen Vorrichtung an den mindestens einen Kartenleser und/oder die Druckeinrichtung sendbar sind,
  • daß die an den oder die Kartenleser gesandten Daten auf eine in den oder die Kartenleser eingeführte Karte schreibbar sind und
  • daß die an die Druckeinrichtung gesandten Daten von der Druckeinrichtung druckbar sind.
The solution is characterized by
  • that the tachograph is equipped with at least one card reader and a printing device,
  • that the tachograph has an interface for its connection to a data bus,
  • that data read by the at least one card reader can be transmitted to at least one further device connected to the data bus,
  • that data can be sent from at least one further device connected to the data bus to the at least one card reader and / or the printing device,
  • that the data sent to the card reader (s) can be written onto a card inserted into the card reader (s) and
  • that the data sent to the printing device can be printed by the printing device.

Beim eingesetzten Datenbus handelt es sich vorzugsweise um einen CAN-Bus, weil dieser in der Fahrzeugtechnik die weiteste Verbreitung gefunden hat. Grundsätzlich ist die vorgeschlagene Lösung aber auch für andere Datenbussysteme verwendbar. Als Kartenleser kommt in erster Linie ein Chipkartenleser zum Einsatz.The data bus used is preferably a CAN bus because This has found the most widespread use in vehicle technology. Basically the proposed solution can also be used for other data bus systems. A chip card reader is primarily used as the card reader.

Der besondere Vorteil dieser Lösung besteht darin, daß auf diese Weise der Kartenleser und/oder die Druckeinrichtung im Fahrzeug als multifunktionales Eingabe- bzw. Ausgabegerät für mehrere im Fahrzeug befindliche und über einen gemeinsamen Datenbus miteinander vernetzte Geräte zur Verfügung stehen. So können zum Beispiel Meßdaten anderer Fahrzeugeinrichtungen, zum Beispiel von Diagnoseeinrichtungen, unter Verwendung der Druckeinrichtung des Fahrtschreibers in einem Schriftstück ausgegeben und damit protokolliert werden. In umgekehrter Datenübertragungsrichtung können Daten beispielsweise zur Programmierung diverser Fahrzeugeinrichtungen, zum Beispiel eines Bordcomputers oder des Motormanagements, mittels eines mobilen Datenträgers, d.h. einer entsprechend programmierten Datenkarte, über den Kartenleser des Fahrtschreibers eingegeben werden. Durch die erweiterte Funktionalität von Einrichtungen des Fahrtschreibers kann eine Vielzahl von Spezialgeräten entfallen, die heute im Datenaustausch mit einzelnen Fahrzeugeinrichtungen benötigt werden. Diese funktionelle Erweiterung wird dadurch erreicht, daß der Fahrtschreiber bezüglich seiner Ein- und Ausgänge mit einer geeigneten Schnittstelle ausgestattet wird und die Steuereinheit des Fahrtschreibers ein entsprechendes Steuerprogramm erhält.The particular advantage of this solution is that in this way the Card reader and / or the printing device in the vehicle as a multifunctional Input or output device for several in the vehicle and via one devices that are networked with each other are available. So For example, measurement data from other vehicle devices, for example from Diagnostic devices using the tachograph's printing device issued in a document and thus logged. In reverse Data transmission direction can be data for programming, for example various vehicle equipment, for example an on-board computer or the Engine management, by means of a mobile data carrier, i.e. one accordingly programmed data card, entered via the card reader of the tachograph become. Through the expanded functionality of tachograph equipment a large number of special devices can be omitted, which are used today in data exchange with individual vehicle facilities are required. This functional extension is achieved in that the tachograph with regard to its inputs and outputs is equipped with a suitable interface and the control unit of the Tachograph receives a corresponding control program.

Die Kommunikation zwischen den Fahrtschreibereinrichtungen wie dem mindestens einen Kartenleser bzw. der Druckeinrichtung und der mindestens einen weiteren an den Datenbus angeschlossenen Vorrichtung wird durch Kennungen gesteuert. Wenn beispielsweise der Kartenleser beim Einlesen von Daten von einer in ihn eingelegten Karte auf eine Kennung stößt, die nicht den Fahrtschreiber identifiziert, schaltet die im Fahrtschreiber vorgesehene Steuereinheit dessen Schnittstelle zum Datenbus selbsttätig in einen Betriebszustand, in welchem die eingelesenen Daten unmittelbar auf den Datenbus gegeben und so der durch die Kennung adressierten Vorrichtung, die ebenfalls an den Datenbus angeschlossen ist, übermittelt werden. Die Steuereinheit des Fahrtschreibers wird somit um die Funktion einer durch Kennungen gesteuerten Weiche für Datenströme erweitert. Die übrigen Fahrtschreiberfunktionen bleiben jedoch von dem genannten Datentransfer unberührt.The communication between the tachograph facilities like that at least a card reader or the printing device and the at least one other the device connected to the data bus is controlled by identifiers. If for example, the card reader when reading data from one inserted into it If the card encounters an identifier that does not identify the tachograph, it switches Control unit provided in the tachograph, its interface to the data bus automatically in an operating state in which the read data immediately placed on the data bus and thus the device addressed by the identifier, which are also connected to the data bus. The Control unit of the tachograph is thus a function of Identifier controlled switch for data streams extended. The remaining Tachograph functions, however, remain from the aforementioned data transfer untouched.

Ebenso können auch Daten von anderen an dem Datenbus angeschlossenen Vorrichtungen an den mindestens einen Kartenleser und/oder die Druckeinrichtung gesendet werden, wobei eine mit den Daten übertragene Kennung zunächst die Schnittstelle des Fahrtschreibers adressiert und dann vorgibt, welcher Datenausgabeeinrichtung des Fahrtschreibers die empfangenen Daten zur weiteren Verarbeitung zuzuführen sind.Data from others can also be connected to the data bus Devices on the at least one card reader and / or the printing device are sent, an identifier transmitted with the data first being the Interface of the tachograph is addressed and then specifies which Data output device of the tachograph for further data received Processing must be supplied.

Falls der oder die Kartenleser bzw. die Druckeinrichtung nicht sogleich für die Datenausgabe zur Verfügung stehen, weil sie gerade vom Fahrtschreiber für die Ausgabe fahrtschreiberspezifischer Daten genutzt werden, veranlaßt die Steuereinheit des Fahrtschreibers eine Zwischenspeicherung der empfangenen Daten in Speichermitteln des Fahrtschreibers oder signalisiert der über den Datenbus sendenden Vorrichtung, daß die angewählte Ausgabeeinrichtung gegenwärtig besetzt und damit für die Verarbeitung des empfangenen Auftrages nicht bereit ist.If the one or more card readers or the printing device is not immediately for the Data output is available because it is used by the tachograph for the Output of tachograph-specific data is used, causes the Control unit of the tachograph caching the received Data in the tachograph's storage means or signaled by the Data bus sending device that the selected output device currently busy and thus for the processing of the received order is not ready.

Anhand einer Figur soll die vorgeschlagene Lösung nochmals kurz erläutert werden. Wie das vereinfachte Blockschaltbild zeigt, sind mehrere verschiedene Fahrzeugeinrichtungen, wie beispielsweise das Motormanagement 5, ein Bordcomputer 6 und eine Diagnoseeinrichtung 7 durch einen Datenbus 4 miteinander verbunden. Auch der Fahrtschreiber 1 ist an diesen Datenbus 4 angeschlossen. Alle miteinander vernetzten Fahrzeugeinrichtungen sind so ausgebildet, daß sie miteinander kommunizieren können. Dafür sind in den einzelnen Einrichtungen geeignete Schnittstellen vorgesehen, die hier aber nicht näher dargestellt sind. Der Fahrtschreiber 1 verfügt sowohl über mindestens eine Dateneingabeeinrichtung 2 als auch über eine Datenausgabeeinrichtung 3. Die Dateneingabeeinrichtung 2 ist als Kartenleser ausgestaltet. Als Datenausgabeeinrichtung 3 kann eine Druckeinrichtung und/oder ein Kartenleser vorgesehen sein. Der Fahrtschreiber 1 verfügt nun über eine Steuereinheit, die vom Datenbus eingehende Datenströme an die Datenausgabeeinrichtung 3 weiterleitet oder die von der Dateneingabeeinrichtung 2 aufgenommene Daten an Einrichtungen abgibt, die an den Datenbus 4 angeschlossen sind. Mit den Daten übertragene Kennungen enthalten die jeweilige Zieladresse, damit die Steuereinheit des Fahrtschreibers die gewünschte Zuordnung vornehmen kann.The proposed solution will be briefly explained again using a figure . As the simplified block diagram shows, several different vehicle devices, such as the engine management 5, an on-board computer 6 and a diagnostic device 7 are connected to one another by a data bus 4. The tachograph 1 is also connected to this data bus 4. All networked vehicle devices are designed so that they can communicate with each other. Suitable interfaces are provided for this in the individual facilities, but these are not shown in detail here. The tachograph 1 has both at least one data input device 2 and one data output device 3. The data input device 2 is designed as a card reader. A printing device and / or a card reader can be provided as the data output device 3. The tachograph 1 now has a control unit which forwards data streams arriving from the data bus to the data output device 3 or which outputs data recorded by the data input device 2 to devices which are connected to the data bus 4. Identifiers transmitted with the data contain the respective destination address, so that the tachograph control unit can make the desired assignment.
