Description
Die vorliegende Erfindung betrifft eine Anordnung, bestehend aus einer Positionsmesseinrichtung, mindestens einer Peripherieeinheit, einer Steuereinheit und einer elektronische Zwischenbaugruppe.The present invention relates to an arrangement comprising a position-measuring device, at least one peripheral unit, a control unit and an electronic intermediate module.
Aus der
Weitere Probleme ergeben sich, wenn außer den Daten des Temperatursensors noch weitere Daten anderer Peripherieeinheiten zur Positionsmesseinrichtung und anschließend über die serielle Kommunikationsverbindung an eine nachgeordnete Steuereinheit übertragen werden sollen, beispielsweise die Daten von Beschleunigungssensoren etc.. So resultiert im Fall mehrerer derartiger Peripherieeinheiten das Problem, dass die jeweilige Positionsmesseinrichtung dann eine entsprechende Vielzahl von Schnittstellen, Steckverbindungen etc. für die weiteren Peripherieeinheiten aufweisen muss.Further problems arise if, in addition to the data of the temperature sensor, further data of other peripheral units are to be transmitted to the position measuring device and then via the serial communication link to a downstream control unit, for example the data of acceleration sensors, etc. Thus, in the case of several such peripheral units, the problem arises that the respective position-measuring device then has to have a corresponding multiplicity of interfaces, plug connections etc. for the further peripheral units.

Über eine einzige ausgangsseitige Schnittstelle ist die Sensor-Abfrageeinheit mit einer einer zentralen Steuereinheit für die jeweilige Anwendung verbunden. Über eine weitere Schnittstelle werden der zentralen Steuereinheit Daten eines Drehgebers zugeführt. Die hier vorgeschlagene Architektur ist nicht geeignet, eine Mehrzahl von Sensoren an eine Positionsmesseinrichtung anzubinden.Via a single output-side interface, the sensor interrogation unit is connected to a central control unit for the respective application. Via a further interface, the data of a rotary encoder are fed to the central control unit. The architecture proposed here is not suitable for connecting a plurality of sensors to a position-measuring device.
Die
Aufgabe der vorliegenden Erfindung ist es daher, eine Lösung anzugeben, über die die Übertragung von Daten verschiedener Peripherieeinheiten über eine serielle Kommunikationsverbindung zwischen einer Positionsmesseinrichtung und einer Steuereinheit möglichst ungestört und mit wenig Aufwand zu bewerkstelligen ist.Object of the present invention is therefore to provide a solution over which the transfer of data from different peripheral units via a serial communication link between a position measuring device and a control unit as undisturbed and with little effort to accomplish.
Diese Aufgabe wird gelöst durch eine Anordnung mit den Merkmalen des Anspruches 1.This object is achieved by an arrangement having the features of claim 1.
Vorteilhafte Ausführungsformen der erfindungsgemäßen Anordnung ergeben sich aus den Maßnahmen, die in den von Anspruch 1 abhängigen Patentansprüchen aufgeführt sind.Advantageous embodiments of the arrangement according to the invention will become apparent from the measures listed in the dependent claims of claim 1.
Erfindungsgemäß ist nunmehr vorgesehen, zwischen der Positionsmesseinrichtung und der mindestens einen Peripherieeinheit eine elektronische Zwischenbaugruppe anzuordnen, die in bestimmter Art und Weise ausgebildet ist. So umfasst die Zwischenbaugruppe ein oder mehrere Datenerfassungs-Schnittstellen, über die die Übertragung von Daten von ein oder mehreren Peripherieeinheiten in Richtung der Zwischenbaugruppe erfolgt. Des weiteren ist eine Kommunikations-Schnittstelle für eine Kommunikationsverbindung in der Zwischenbaugruppe vorgesehen, die zur vorzugsweise seriellen Übertragung der Daten von der Zwischenbaugruppe zur Positionsmesseinrichtung ausgebildet ist.According to the invention, it is now provided to arrange an electronic intermediate module between the position-measuring device and the at least one peripheral unit, which is designed in a specific manner. Thus, the intermediate assembly comprises one or more data acquisition interfaces, via which the transmission of data from one or more peripheral units takes place in the direction of the intermediate module. Furthermore, a communication interface is provided for a communication connection in the intermediate module, which is designed for preferably serial transmission of the data from the intermediate module to the position measuring device.
Die Datenerfassungs-Schnittstellen in der Zwischenbaugruppe können hierbei sowohl zur Übertragung von Analogdaten als auch zur seriellen Übertragung von Daten zwischen der Zwischenbaugruppe und den Peripherieeinheiten ausgebildet sein, je nachdem welche Art von Peripherieeinheiten vorgesehen sind.In this case, the data acquisition interfaces in the intermediate module can be designed both for the transmission of analog data and for the serial transmission of data between the intermediate module and the peripheral units, depending on which type of peripheral units are provided.
Das Vorsehen einer derart ausgebildeten Zwischenbaugruppe bietet eine Reihe von Vorteilen. So ist zum einen eine Entkopplung zwischen der mindestens einen Peripherieeinheit und der Elektronik der Positionsmesseinrichtung gewährleistet, so dass insbesondere seitens der Elektronik keine Störeinflüsse mehr resultieren. Zum anderen muss auf Seiten der Positionsmesseinrichtung unabhängig von der Zahl und Art eventueller Peripherie-Einheiten nur noch eine Schnittstelle zur Kommunikation mit der Zwischenbaugruppe bereit gestellt werden; entsprechend geringer ist dementsprechend der Verkabelungsaufwand auch im Fall mehrerer eingesetzter Peripherieeinheiten, deren Daten in Richtung einer nachgeordneten Steuereinheit zu übertragen sind. Über die Zwischenbaugruppe können des weiteren unterschiedlichste Peripherieeinheiten an die Positionsmesseinrichtung angebunden werden, die jeweils zeitunkritische Daten liefern, welche über die Zwischenbaugruppe und die Positionsmesseinrichtung letztlich an die nachgeordnete Steuereinheit übertragen werden. Neben verschiedensten Sensoren - beispielsweise geeignet zur Temperaturmessung - kann es sich bei derartigen Peripherieeinheiten des weiteren auch um Speicherbausteine etc. handeln, die z.B. anordnungsspezifische Daten beinhalten.The provision of a thus formed intermediate assembly offers a number of advantages. Thus, on the one hand, a decoupling between the at least one peripheral unit and the electronics of the position-measuring device is ensured so that, in particular on the part of the electronics, no disturbing influences result. On the other hand, regardless of the number and type of any peripheral units, only one interface for communication with the intermediate module must be provided on the side of the position-measuring device; Correspondingly smaller accordingly is the cabling effort even in the case of several inserted peripheral units whose data are to be transmitted in the direction of a downstream control unit. Furthermore, a wide variety of peripheral units can be connected to the position-measuring device via the intermediate module, which in each case deliver non-time-critical data which is ultimately transmitted via the intermediate module and the position-measuring device to the downstream control unit. In addition to a wide variety of sensors - for example, suitable for temperature measurement - such peripheral units may also be memory modules, etc., which contain, for example, arrangement-specific data.
Weitere Vorteile sowie Einzelheiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der beiliegenden Figur.Further advantages and details of the present invention will become apparent from the following description of an embodiment with reference to the accompanying figure.
Diese zeigt ein schematisiertes Blockschaltbild einer erfindungsgemäßen Anordnung, bestehend aus einer Positionsmesseinrichtung 10, einer Zwischenbaugruppe 20, mehreren Peripherieeinheiten 31, 32, 33 und einer Steuereinheit 40. Eine derartige Anordnung kann etwa in einer Werkzeugmaschine vorgesehen sein, wobei mittels der Positionsmesseinrichtung 10 die Position eines beweglichen Teiles bestimmt werden, das über einen - nicht dargestellten - elektrischen Antrieb positioniert wird. Die derart ermittelten Positionsdaten werden zu Regelungszwecken an eine nachgeordnete Steuereinheit 40 in Form einer numerischen Werkzeugmaschinensteuerung übergeben.This shows a schematic block diagram of an inventive arrangement consisting of a
Als Peripherieeinheiten 31, 32, 33 fungieren in einer derartigen Ausführungsvariante beispielsweise ein erster Temperatursensor 31, ein zweiter Temperatursensor 32 und ein Speicherbaustein 33. Über die Temperatursensoren 31, 32 werden unterschiedliche Temperaturen erfasst, etwa die Wicklungstemperatur des elektrischen Antriebs etc.; die über diese Peripherieeinheiten 31, 32 ermittelten Daten bzw. Messwerte werden nach der - noch zu erläuternden Übertragung - auf Seiten der Steuereinheit 40 zu Steuer- und Regelungszwecken in bekannter Art und Weise weiterverarbeitet.As
Die in diesem Beispiel ferner vorgesehene dritte Peripherieeinheit 33 ist als Speicherbaustein ausgebildet, der z.B. entfernt von der Positionsmesseinrichtung 10 auf Seiten des Antriebes angeordnet ist und anordnungsspezifische Daten enthält, die ebenfalls von der Steuereinheit 40 weiterverarbeitet werden. Bei derartigen anordnungsspezifischen Daten kann es sich beispielsweise um Motorkenndaten etc. handeln, die zur automatisierten Inbetriebnahme des Gesamtsystems dienen.The third
Grundsätzlich kann es sich bei den verschiedenen Peripherieeinheiten demzufolge um Sensoren handeln, die i.w. zur Erfassung von zeitunkritischen Messgrößen ausgebildet sind, die dann in der Steuereinheit weiterverarbeitet werden. Alternativ ist an dieser Stelle wie erläutert auch der Einsatz von ein- und auslesbaren Speicherbausteinen als Peripherieeinheit möglich. Selbstverständlich können darüber hinaus noch weitere Varianten von Peripherieeinheiten an dieser Stelle zum Einsatz kommen.Basically, the various peripheral units can therefore be sensors which i.w. are designed to detect non-time-critical quantities, which are then further processed in the control unit. Alternatively, as explained, the use of readable and readable memory modules as a peripheral unit is possible at this point. Of course, further variants of peripheral units can also be used at this point.
Anstelle wie bislang die Daten derartiger Peripherieeinheiten 31, 32, 33 unmittelbar der Positionsmesseinrichtung 10 zuzuführen und die Daten über die serielle Kommunikationsverbindung 50 an die Steuereinheit 40 zu übertragen, ist nunmehr der Einsatz der elektronischen Zwischenbaugruppe 20 vorgesehen. Dieser werden wie aus der Figur ersichtlich zunächst die Daten der mindestens einen Peripherieeinheit 31, 32, 33 zugeführt, bevor diese Daten an die Positionsmesseinrichtung 10 übertragen werden.Instead of supplying the data of such
Wie aus der Darstellung in der Figur ferner erkennbar, umfasst die Zwischenbaugruppe 20 im vorliegenden Beispiel hierzu drei schematisiert angedeutete Datenerfassungs-Schnittstellen 21.1, 21.2, 21.3 bzw. Datenerfassungseingänge für drei Datenübertragungsverbindungen 60.1, 60.2, 60.3 zu den Peripherieeinheiten 31, 32, 33. Die Datenübertragungsverbindungen 60.1, 60.2, 60.3. sind hierbei jeweils zur Übertragung von Daten zwischen der jeweiligen Peripherieeinheit 31, 32, 33 und der Zwischenbaugruppe 20 ausgebildet. Je nach Art der Peripherieeinheit 31, 32, 33 kann die Datenübertragung zwischen der Peripherieeinheit 31, 32, 33 und Zwischenbaugruppe 20 variieren; dementsprechend unterschiedlich ist dann selbstverständlich auch die Datenerfassungs-Schnittstelle 21.1, 21.2, 21.3 der Zwischenbaugruppe 20 auszubilden. So werden etwa im Fall der als Temperatur- und Beschleunigungssensoren ausgebildeten Peripherieeinheiten 31, 32 die erzeugten Messwerte als Analogdaten an die Zwischenbaugruppe 20 übertragen; dementsprechend sind die zugehörigen Datenerfassungs-Schnittstellen 21.1, 21.2 so auszubilden, dass die Übertragung von Analogdaten zwischen den Peripherieeinheiten 31, 32 und der Zwischenbaugruppe 33 möglich ist. Im Fall der als Speicherbaustein ausgebildeten dritten Peripherieeinheit 33 dieses Beispiels ist hingegen eine serielle Übertragung von Daten zwischen dem Speicherbaustein 33 und der Zwischenbaugruppe 20 vorgesehen; entsprechend muss dann die Datenerfassungs-Schnittstelle 21.3 so ausgebildet sein, dass eine serielle Datenübertragung zwischen dem Speicherbaustein 33 und der Zwischenbaugruppe 20 möglich ist.As can also be seen from the illustration in the figure, the
Die derart in die Zwischenbaugruppe 20 übertragenen Daten werden in der Zwischenbaugruppe 20 anschließend - in noch zu erläuternder Art und Weise - weiterverarbeitet und ausgangsseitig zur Übertragung über die erste serielle Kommunikationsverbindung 70 an die Positionsmesseinrichtung 10 bereit gestellt. Hierzu weist die Zwischenbaugruppe 20 eine Kommunikations-Schnittstelle 22 für die erste Kommunikationsverbindung 70 auf, über die eine serielle Übertragung von Daten zwischen der Zwischenbaugruppe 20 und der Positionsmesseinrichtung 10 erfolgt.The data thus transferred to the
Auf Seiten der Positionsmesseinrichtung 10 ist zu diesem Zweck eine erste Kommunikationsschnittstelle 12 für die erste, vorzugsweise serielle Kommunikationsverbindung 70 zur Zwischenbaugruppe 20 vorgesehen. Ferner weist die Positionsmesseinrichtung 10 eine zweite Kommunikationsschnittstelle 13 für eine zweite, ebenfalls vorzugsweise serielle Kommunikationsverbindung 50 auf, über der die Datenübertragung zwischen der Positionsmesseinrichtung 10 und der nachgeordneten Steuereinheit 40 abgewickelt wird.On the part of the
Auf Seiten der Positionsmesseinrichtung 10 werden demzufolge die von der Zwischenbaugruppe übertragenen zeitunkritischen Daten der verschiedenen Peripherieeinheiten 31, 32, 33 zusammen mit den über eine Positionssignalerzeugungseinheit 11 generierten Positionsdaten in einer Signalaufbereitungseinheit 14 derart aufbereitet, dass diese in einem geeigneten seriellen Protokoll über die zweite Kommunikationsverbindung 50 zur Steuereinheit 40 übertragbar sind.On the part of the
In der Zwischenbaugruppe 20 sind zwischen den Datenerfassungs-Schnittstellen 21.1, 21.2, 21.3 und der Kommunikations-Schnittstelle 22 in schematisierter Form eine Reihe weiterer Komponenten angedeutet, deren prinzipielle Funktion nachfolgend erläutert sei. Es sei an dieser Stelle darauf hingewiesen, dass die Art, Anzahl und Ausgestaltung dieser Komponenten je nach anzuschließenden Peripherieeinheiten durchaus variieren kann.In the
So umfasst im vorliegenden Beispiel die Zwischenbaugruppe 20 ferner eine A/D-Wandlereinheit 23, die zur Digitalisierung der von den beiden Peripherieeinheiten 31, 32 gelieferten Analogdaten dient.Thus, in the present example, the
Zur Weiterverarbeitung der in diesem Beispiel jeweils digitalisiert vorliegenden Daten der Peripherieeinheiten 31, 32, 33 ist ferner eine Signalverarbeitungseinheit 24 in der Zwischenbaugruppe 20 vorgesehen. Darüber kann beispielsweise eine geeignete Verarbeitung der Messgrößen der beiden Peripherieeinheiten 31, 32 erfolgen; hierbei kann es sich etwa um eine geeignete Filterung der gelieferten Temperaturdaten handeln, eine Signalüberwachung incl. Alarmgenerierung etc..For further processing of the data of the
Ebenfalls schematisiert ist in der Figur auf Seiten der Zwischenbaugruppe ferner noch eine Signalaufbereitungseinheit 25 angedeutet, die im wesentlichen für die Aufbereitung der von den Peripherieeinheiten 31, 32, 33 gelieferten bzw. übertragenen Daten zur seriellen Übertragung über die Kommunikations-Schnittstelle 22 sorgt.Also schematically indicated in the figure on the part of the intermediate module also a
Im Fall der ersten seriellen Kommunikationsverbindung 70 zwischen der Zwischenbaugruppe 20 und der Positionsmesseinrichtung kann es sich beispielsweise um eine sog. I2C-Schnittstelle handeln. Die gleiche Schnittstellenarchitektur kann im übrigen auch vorteilhafterweise im Fall der seriellen Datenübertragungsverbindung 60.3 zwischen der Zwischenbaugruppe 20 und der als Speicherbaustein ausgebildeten Peripherieeinheit 33 vorgesehen werden. Grundsätzlich können an dieser Stelle jedoch auch weitere bekannte serielle Schnittstellenarchitekturen zum Einsatz kommen.In the case of the first
Bei der zweiten seriellen Kommunikationsverbindung 50 zwischen der Positionsmesseinrichtung 10 und der nachgeordneten Steuereinheit 40 kann es sich beispielsweise um eine Schnittstellenarchitektur auf Ethernet-Basis handeln, über die der Datentransfer abgewickelt wird. Grundsätzlich kommen an dieser Stelle jedoch auch andere bekannte serielle SchnittstellenArchitekturen in Betracht.The second
Alternativ zur in der Figur dargestellten Anordnung aus Positionsmesseinrichtung, Zwischenbaugruppe und Steuereinheit gibt es grundsätzlich auch andere Anordnungsvarianten. Beispielsweise wäre es auch möglich, die Zwischenbaugruppe zwischen Steuereinheit und Positionsmesseinrichtung anzuordnen. Die von den Peripherieeinheiten gelieferten Daten werden über die Datenerfassungs-Schnittstellen der Zwischenbaugruppe zunächst in die Zwischenbaugruppe übertragen und dann über die Kommunikations-Schnittstelle in die Positionsmesseinrichtung. Dort werden diese Daten zusammen mit den Positionsdaten zur seriellen Übertragung an die Steuereinheit aufbereitet und über die Zwischenbaugruppe schließlich an die Steuerereinheit übertragen. In diesem Fall wäre es zudem denkbar, in der Zwischenbaugruppe eine Spannungsversorgung für die Positionsmesseinrichtung unterzubringen.As an alternative to the arrangement of position-measuring device, intermediate module and control unit shown in the figure, there are basically also other arrangement variants. For example, it would also be possible to arrange the intermediate module between the control unit and the position-measuring device. The data supplied by the peripheral units are first transferred via the data acquisition interfaces of the intermediate module in the intermediate module and then via the communication interface in the position measuring device. There, these data are processed together with the position data for serial transmission to the control unit and finally transmitted via the intermediate module to the control unit. In this case, it would also be conceivable to accommodate a voltage supply for the position-measuring device in the intermediate module.
Im Rahmen der vorliegenden Erfindung existieren somit neben dem erläuterten Ausführungsbeispiel vielfältige weitere Ausgestaltungsmöglichkeiten.In the context of the present invention, therefore, there are numerous further design possibilities in addition to the exemplary embodiment explained.
