Abstract
Description
Die Neuerung bezieht sich auf eine Schaltungsanordnung zur Codeumwandlung. Daten und insbesondere Meß- und Steuerdaten liegen häufig in unterschiedlichen Formaten und verpackt in sog. "Protokollen" vor und müssen zur Weiterverarbeitung in andere Formate und/oder Protokolle umgesetzt werden. Beispielsweise sind moderne Kraftfahrzeuge mit einem sog. CAN-Bus ausgerüstet, über den diverse Meß- und Steuerdaten innerhalb des Kraftfahrzeuges übertragen werden. Zu Diagnosezwecken kann ein Meßgerät an den CAN-Bus angeschlossen werden, das seinerseits zur Auswertung der Daten an einen Computer angeschlossen ist, der bei Bedarf die im CAN-Protokoll empfangenen Daten in ein anderes Protokoll umsetzt. Übliche Protokolle sind dabei das Ethernet-Protokoll oder auch LAN (für Local Area Network), das WLAN (Wireless LAN), USB (Universal Serial Bus), "Firewire" usw. Die Codeumwandlung wird bisher in Computern durchgeführt, die dann spezielle Eingangsschnittstellen für den jeweiligen Bustyp haben müssen, was in der Praxis nicht immer der Fall ist.The innovation relates to one Circuitry for code conversion. Data and in particular measurement and control data are often in different formats and packed in so-called "protocols" and must be sent to Further processing in other formats and / or protocols can be implemented. For example, modern motor vehicles with a so-called CAN bus equipped over the various measurement and control data transmitted within the motor vehicle become. A measuring device can be connected to the CAN bus for diagnostic purposes. which in turn is connected to a computer for evaluating the data is, if necessary, the data received in the CAN protocol implements another protocol. usual The protocols are the Ethernet protocol or LAN (for local area Network), the WLAN (Wireless LAN), USB (Universal Serial Bus), "Firewire" etc. The code conversion is previously carried out in computers, which then have special input interfaces for the must have the respective bus type, which is not always the case in practice.
Aufgabe der Neuerung ist es daher, eine Schaltungsanordnung zur Codeumwandlung zu schaffen, die universell einsetzbar ist und keinen vollständigen Computer benötigt.The task of the innovation is therefore to create circuitry for code conversion that is universal is usable and not a complete one Computer needed.
Diese Aufgabe wird durch die im Schutzanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Neuerung sind den Unteransprüchen zu entnehmen.This task is covered by the protection claim 1 specified features solved. Advantageous refinements and developments of the innovation are the subclaims refer to.
Das Grundprinzip der Neuerung liegt darin, nur die für eine Codeumwandlung benötigten Bauteile, nämlich mindestens eine Eingangsschnittstelle, mindestens eine Ausgangsschnittstelle und einen Mikrocontroller mit Speicher in einem kleinen Gehäuse anzuordnen. Eine solche kleine "Box" führt dann die gewünschte Codeumwandlung, beispielsweise von CAN-Bus auf LAN durch und kann jeweils an Ort und Stelle, beispielsweise unmittelbar an bzw. in einem Kraftfahrzeug, z.B. auch direkt im Motorraum, eingesetzt werden.The basic principle of the innovation lies in it, only for needed a code conversion Components, namely at least one input interface, at least one output interface and to place a microcontroller with memory in a small package. Such a small "box" then leads the desired Code conversion, for example from CAN bus to LAN through and can each on the spot, for example directly on or in an automobile, e.g. can also be used directly in the engine compartment.
Vorzugsweise sind in dem Gehäuse mehrere Eingangsschnittstellen für unterschiedliche Formate, wie z.B. CAN-Bus, Profibus oder sonstige bekannte Bus-Protokolle vorgesehen. Weiterhin sind in vorteilhafter Weise auch mehrere unterschiedliche Ausgangsschnittstellen vorgesehen, beispielsweise für WLAN, LAN, USB, Firewire oder Bluetooth.There are preferably a plurality of input interfaces in the housing for different Formats such as CAN bus, Profibus or other known bus protocols intended. Furthermore, several different ones are also advantageous Output interfaces provided, for example for WLAN, LAN, USB, Firewire or Bluetooth.
Die Energieversorgung der Schaltungsanordnung kann entweder über eine intern im Gehäuse vorhandene Batterie erfolgen oder extern entweder über eine externe Energiequelle oder über den jeweiligen Bus an der Eingangsschnittstelle, sofern diese einen Stromversorgungsanschluß hat.The power supply of the circuit arrangement can either over one existing internally in the housing Battery or external either via an external energy source or about the respective bus at the input interface, if this one Has power supply connection.
Vorzugsweise hat der Mikroprozessor zwei Speicher und zwar einen Nur-Lese-Speicher (ROM), in dem ein Programm fest gespeichert ist, das den Mikroprozessor (CPU) anweist, eingehend Meldungen über eine der physikalischen Schnittstellen zu empfangen, die Meldungen entsprechend dem jeweiligen Empfangs-Protokoll auszuwerten, in ein anderes Protokoll umzusetzen und über eine der physikalischen Ausgangsschnittstellen zu senden. Weiter enthält die CPU einen Speicher mit wahlfreiem Zugriff (RAM), der als Arbeitsspeicher für die Rechenoperationen dient.Preferably the microprocessor two memories, namely a read-only memory (ROM), in which one Program that instructs the microprocessor (CPU) reports about one of the physical interfaces to receive the messages in accordance with the respective reception protocol implement another protocol and one of the physical To send output interfaces. The CPU also contains a memory random access (RAM), which acts as memory for computing operations serves.
Vorzugsweise sind die einzelnen Eingangs- und Ausgangsschnittstellen als steckbare Module ausgebildet, die bei Bedarf ausgetauscht werden können.The individual input and Output interfaces designed as plug-in modules, which at Need can be exchanged.
Im folgenden wird die Neuerung anhand eines Ausführungsbeispieles im Zusammenhang mit der Zeichnung ausführlicher erläutert. Es zeigt:In the following the innovation is based of an embodiment explained in more detail in connection with the drawing. It shows:
