Description

Die Erfindung betrifft ein Verfahren zum Erfassen einer Konfiguration von mehreren Hubvorrichtungen in einem Hubsystem.The invention relates to a method for detecting a configuration of a plurality of lifting devices in a lifting system.

Ein derartiges Verfahren ist aus der EP-A-1 015 376 bekannt.Such a method is known from EP-A-1 015 376 known.

Aus der EP 1 285 878 A1 ist ein Hubsystem bekannt geworden, das zumindest zwei Hubvorrichtungen umfasst, die aus einem Grundgestell und einer Hubeinheit bestehen. Die Hubeinheit weist einen Hubzylinder auf, um ein Lastaufnahmemittel zum Heben und Senken der Last auf und ab zu bewegen. Die Hubvorrichtungen sind mit Versorgungsleitungen verbunden, so dass eine gemeinsame Ansteuerung ermöglicht ist.From the EP 1 285 878 A1 a lifting system has become known which comprises at least two lifting devices, which consist of a base frame and a lifting unit. The lifting unit has a lifting cylinder to move a load receiving means for lifting and lowering the load up and down. The lifting devices are connected to supply lines, so that a common control is enabled.

Bislang ist bekannt, dass die Hubvorrichtungen codiert werden. Beim Aufstellen dieser Hubvorrichtungen ist es jedoch erforderlich, dass eine durch die Codierung vorgegebene Reihenfolge der Hubvorrichtungen einzuhalten ist. Dies erfordert eine besondere Aufmerksamkeit beim Aufstellen mehrerer Hubvorrichtungen. Darüber hinaus ist eine wahlweise Anordnung der Hubvorrichtungen zur Bildung eines Hubsystems nicht ermöglicht.So far it is known that the lifting devices are coded. When setting up these lifting devices, however, it is necessary that a is to be followed by the coding predetermined order of the lifting devices. This requires special attention when setting up several lifting devices. In addition, an optional arrangement of the lifting devices for forming a lifting system is not possible.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren zur Erfassung einer Konfiguration von mehreren Hubvorrichtungen in einem Hubsystem zu schaffen, durch welches die Hubvorrichtungen vor dem Heben und Senken einer Last innerhalb des Hubsystems eine eindeutige Zuordnung zueinander erhalten und die Anzahl der im Hubsystem eingebundenen Hubvorrichtungen erfasst wird.The invention is therefore based on the object to provide a method for detecting a configuration of several lifting devices in a lifting system by which the lifting devices before lifting and lowering a load within the lifting system get a clear relationship to each other and the number of embedded in the lifting system lifting devices is detected.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gemäß den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind in den weiteren abhängigen Ansprüchen angegeben.This object is achieved by a method according to the features of claim 1. Further advantageous embodiments are specified in the further dependent claims.

Durch das erfindungsgemäße Verfahren ist ermöglicht, dass eine beliebige Anzahl von Hubvorrichtungen zur Bildung eines Hubsystem konfiguriert werden. Dies bedeutet, dass eine erste Hubvorrichtung als Masterhubvorrichtung initialisiert wird und die nachfolgenden Hubvorrichtungen über diese Masterhubvorrichtung gesteuert werden und eine auf die Masterhubvorrichtung aufbauende Knotenadresse erhalten. Diese nacheinander erfolgende Initialisierung der in Reihe zur Masterhubvorrichtung angeordneten weiteren Hubvorrichtungen und deren Zuordnung einer Knotenadresse wird so lange fortgeführt, bis die letzte Hubvorrichtung erreicht wurde. Aufgrund einer dort vorgesehenen Initialisierung, die ein offenes Ende der in Reihe zueinander angeordneten Hubvorrichtungen signalisiert, erhält die Masterhubvorrichtung ein Signal, dass alle dazwischen liegenden Hubvorrichtungen sukzessive initialisiert wurden, so dass das Verfahren der Konfiguration abgeschlossen wird.The inventive method allows any number of lifting devices to be configured to form a lifting system. This means that a first lifting device is initialized as a master lifting device and the subsequent lifting devices are controlled via this master lifting device and receive a node address based on the master lifting device. This successive initialization of arranged in series to the master lifting device further lifting devices and their assignment of a node address is continued until the last lifting device has been reached. Due to an initialization provided there, which signals an open end of the lifting devices arranged in series, the master lifting device receives a signal that all intermediate lifting devices have been successively initialized so that the method of the configuration is completed.

Dieses Verfahren weist den Vorteil auf, dass nicht codierte Hubvorrichtungen verwendet werden können und in Abhängigkeit des Anwendungsfalles die erforderliche Anzahl der Hubvorrichtungen dem Arbeitsraum zum Heben und Senken der Last beliebig zugeordnet werden, ohne dass eine bestimmte Reihenfolge einzuhalten ist. Gleichzeitig wird durch die Initialisierung der Knotenadressen die Anzahl der im Hubsystem eingebundenen Hubvorrichtungen erfasst. Durch dieses Verfahren können die weiteren Hubvorrichtungen im Hubsystem durch die eine Masterhubvorrichtung aufgrund deren Zuordnung einer Knotenadresse spezifisch angesteuert werden. Gleichzeitig ist ermöglicht, dass beim Auftreten eines Fehlers an der Masterhubvorrichtung oder an jeder anderen Hubvorrichtung eine Fehlermeldung ausgegeben und dem Benutzer angezeigt wird, um welche Hubvorrichtung es sich handelt.This method has the advantage that non-coded lifting devices can be used and, depending on the application, the required number of lifting devices are assigned to the working space for lifting and lowering the load as desired, without a certain order is to be kept. At the same time, the number of lifting devices integrated in the lifting system is detected by the initialization of the node addresses. By this method, the other lifting devices in the lifting system can be specifically controlled by a master lifting device due to their assignment of a node address. At the same time, when an error occurs on the master lifting device or on any other lifting device, it is possible to output an error message and to indicate to the user which lifting device is involved.

Nach einer vorteilhaften Ausgestaltung des Verfahrens ist vorgesehen, dass die mit Versorgungsleitungen verbundenen Hubvorrichtungen in einer offenen U-Form aufgestellt werden und die erste und die letzte Hubvorrichtung am offenen Ende, die zweite und die zweitletzte Hubvorrichtung usw. ein Hebepaar bilden. Dadurch wird die Ansteuerung beim Heben und Senken von mehrachsigen Fahrzeugen erleichtert. Beispielsweise ist bei einem Sattelschlepperzug von Vorteil, lediglich ein Hebepaar, beispielsweise den Auflieger anzuheben, wobei die weiteren Achsen der Zugmaschine durch die jeweils zugeordneten Hebepaare nicht oder in einem geringen Maß angehoben werden.According to an advantageous embodiment of the method it is provided that the lifting devices connected to supply lines are placed in an open U-shape and the first and last lifting device at the open end, the second and the second last lifting device, etc. form a lifting pair. This facilitates the control when lifting and lowering multi-axle vehicles. For example, in a semitrailer tractor is advantageous to lift only one pair of hitches, for example, the trailer, the other axes of the tractor are not raised by the respective associated lifting pairs or to a small extent.

Durch die Zuordnung der Knotenadresse zu jeder Hubvorrichtung ist bevorzugt eine paarweise Zuordnung der einander gegenüberstehenden Hubvorrichtungen ermöglicht. Vorzugsweise ist vorgesehen, dass wenigstens ein Hebepaar für die Hubbewegung angesteuert wird. Dadurch wird die Flexibilität im Einsatz der Hubvorrichtungen erhöht.By assigning the node address to each lifting a pairwise assignment of the opposing lifting devices is preferably possible. It is preferably provided that at least one lifting pair is controlled for the lifting movement. This increases the flexibility in use of the lifting devices.

Alternativ ist nach einer bevorzugten Ausgestaltung des Verfahrens vorgesehen, dass eine Einzelfahrt einer Hubvorrichtung von einer Masterhubvorrichtung angesteuert wird. Dadurch kann eine benutzerdefinierte Einzelauswahl zur Ansteuerung von Hubvorrichtungen erfolgen. Durch eine solche Ansteuerung wird die Flexibilität des Systems erhöht.Alternatively, it is provided according to a preferred embodiment of the method that a single drive a lifting device is controlled by a Masterhubvorrichtung. This allows a user-defined single selection to control lifting devices. Such a control increases the flexibility of the system.

Die als Masterhubvorrichtung vorgesehene Hubvorrichtung wird bevorzugt mit einer Energieversorgung an einem Netz oder an einer autarken Energiequelle angeschlossen, und am Eingang der Steuerung der Masterhubvorrichtung wird ein Eingangspegel gesetzt oder simuliert. Dadurch wird nach dem Verbinden der Hubvorrichtungen über die Versorgungsleitung und deren Initialisierung die Konfiguration gestartet, indem durch den simulierten Eingangspegel die Masterhubvorrichtung sich als solche adressiert, um anschließend die weiteren Konfigurationsschritte einzuleiten.The provided as a master lifting device lifting device is preferably connected to a power supply to a network or to a self-sufficient energy source, and at the input of the control of the Masterhubvorrichtung An input level is set or simulated. As a result, after the lifting devices have been connected via the supply line and their initialization, the configuration is started by the master lifting device being addressed as such by the simulated input level in order subsequently to initiate the further configuration steps.

Des Weiteren ist bevorzugt vorgesehen, dass zumindest eine Hubvorrichtung ohne Energieversorgungsanschluss zwischen zwei Hubvorrichtungen mit Energieversorgungsanschluss in Reihe geschalten werden. Dadurch können die Einspeisungspunkte verringert werden. Gleichzeitig kann sichergestellt werden, dass eine hinreichende Energieversorgung für den Hebe- und Senkvorgang vorgesehen ist.Furthermore, it is preferably provided that at least one lifting device without energy supply connection between two lifting devices with power supply connection are connected in series. This can reduce the feed points. At the same time it can be ensured that a sufficient energy supply for the lifting and lowering process is provided.

Nach einer weiteren vorteilhaften Ausgestaltung des Verfahrens ist vorgesehen, dass ein Hubsystem aus Hubvorrichtungen gebildet wird, die jeweils eine eigene Energieversorgung aufweisen. Dadurch können beliebige Einspeisungspunkte gewählt werden. Des Weiteren ist eine Gleichheit der Hubvorrichtungen gegeben, so dass deren Anordnung beliebig zur Bildung eines Hubsystems vorgesehen ist.According to a further advantageous embodiment of the method is provided that a lifting system is formed from lifting devices, each having its own power supply. As a result, any feed points can be selected. Furthermore, an equality of the lifting devices is given, so that their arrangement is provided as desired to form a lifting system.

Nach einer weiteren vorteilhaften Ausgestaltung des Verfahrens ist vorgesehen, dass die aktuelle Konfiguration der Hubvorrichtungen auf einem Display von zumindest einer Steuerung angezeigt wird. Somit werden die in dem Hubsystem vorhandenen Hubvorrichtungen visualisiert dargestellt. Dadurch ist eine Kontrolle ermöglicht, ob die Anzahl der auf dem Display dargestellten Hubvorrichtungen der Anzahl der sich im System befindlichen Hubvorrichtungen entspricht.According to a further advantageous embodiment of the method is provided that the current configuration of the lifting devices is displayed on a display of at least one controller. Thus, the lifting devices present in the lifting system are visualized. This makes it possible to check whether the number of lifting devices shown on the display corresponds to the number of lifting devices in the system.

Des Weiteren ist bevorzugt vorgesehen, dass im Display die aktivierten und nicht aktivierten Hubvorrichtungen angezeigt werden. Dies kann beispielsweise dergestalt sein, dass ein erstes Paar von Hubvorrichtungen, die aktiviert sind, mit einem Großbuchstaben versehen werden, wohingegen ein weiteres Paar von Hubvorrichtungen, das nicht aktiviert ist, mit einem Buchstaben in Kleinschreibweise dargestellt sind. Alternativ kann auch eine farbliche Unterlegung oder Hervorhebung gegeben sein. Das Display ist bevorzugt an der Masterhubvorrichtung vorgesehen. Alternativ kann auch an jeder Hubvorrichtung ein Display vorgesehen sein, wobei nach der Konfiguration der Hubvorrichtungen und Adressierung in jedem Display der Hubvorrichtung die aktuelle Konfiguration angezeigt wird.Furthermore, it is preferably provided that the activated and not activated lifting devices are displayed. This may, for example, be such that a first pair of lifting devices that are activated are capitalized, whereas another pair of lifting devices that are not activated are represented with a lower case letter. Alternatively, a colored background or highlighting given be. The display is preferably provided on the master lifting device. Alternatively, a display can also be provided on each lifting device, the configuration being displayed after the configuration of the lifting devices and addressing in each display of the lifting device.

In Figur 1 ist ein Hubsystem 11 dargestellt, das beispielsweise aus vier Hubvorrichtungen 12a, 12b, 13a, 13b besteht, die eine Last 14 anheben. Diese Last 14 ist beispielsweise ein Fahrzeug, insbesondere Personenkraftfahrzeug, Lastkraftfahrzeug, Nutzfahrzeug, Panzer oder Schienenfahrzeug. Die Hubvorrichtung 12 besteht aus einem Grundgestell 16 und einer Hubeinheit 17, die ein Lastaufnahmemittel 18 zum Heben und Senken auf und ab bewegen. Im Ausführungsbeispiel ist das Lastaufnahmemittel 18 als Radgreifer ausgebildet, um an einem Reifen des Fahrzeuges anzugreifen beziehungsweise dieses zu untergreifen. Die Hubvorrichtungen 12, 13 sind durch Versorgungsleitungen 21 miteinander verbunden, die sowohl eine Energieversorgung als auch Steuer- und/oder Informationsleitungen umfassen. Diese Versorgungsleitungen 21 sind an Steuerungen 19 der Hubvorrichtungen 12 angeschlossen.In FIG. 1 a lifting system 11 is shown, which consists for example of four lifting devices 12a, 12b, 13a, 13b, which lift a load 14. This load 14 is for example a vehicle, in particular passenger car, truck, commercial vehicle, tank or rail vehicle. The lifting device 12 consists of a base frame 16 and a lifting unit 17, which move a load-receiving means 18 for lifting and lowering up and down. In the exemplary embodiment, the load-receiving means 18 is designed as a wheel gripper to attack on a tire of the vehicle or to engage under this. The lifting devices 12, 13 are interconnected by supply lines 21, which include both a power supply and control and / or information lines. These supply lines 21 are connected to controls 19 of the lifting devices 12.

Die Hubvorrichtungen 12 sind in einer Reihe hintereinander durch die Versorgungsleitungen 21 miteinander verbunden, das heißt, dass die Reihenfolge der Hubvorrichtungen 12a, 12b, 13b, 13a durch die Versorgungsleitungen 21 festgelegt ist. Zwischen den Hubvorrichtungen 12a und 13a ist ein offenes Ende ausgebildet, so dass die Last 14 über dieses offene Ende in einen Arbeitsraum eingebracht werden kann, der zwischen den Hubvorrichtungen 12a, 12b, 13a, 13b liegt beziehungsweise durch diesen umspannt wird.The lifting devices 12 are connected to each other in a row by the supply lines 21, that is, the order of the lifting devices 12a, 12b, 13b, 13a is determined by the supply lines 21. Between the lifting devices 12a and 13a, an open end is formed, so that the load 14 can be introduced via this open end into a working space which lies between the lifting devices 12a, 12b, 13a, 13b or is encompassed by this.

In Figur 2 ist eine schematische Ansicht von mehreren paarweise einander zugeordneten Hubvorrichtungen 12a bis e und 13a bis e vorgesehen, die durch Verbindungsleitungen 21 in Reihe zueinander verbunden sind. Eine solche Anordnung wird beispielsweise für ein fünfachsiges Fahrzeug vorgesehen. Der Aufbau ist analog zu einem zweiachsigen Fahrzeug gemäß Figur 1.In FIG. 2 is a schematic view of a pair of mutually associated lifting devices 12a to e and 13a to e provided, which are connected by connecting lines 21 in series with each other. Such an arrangement is provided for example for a five-axle vehicle. The structure is analogous to a two-axle vehicle according to FIG. 1 ,

Die Anzahl der miteinander zu verbindenden Hubvorrichtungen 12, 13 zur Bildung eines Hubsystems 11 ist abhängig von der zu hebenden Last, so dass für die Überwachung des Hubsystems 11 erforderlich ist, dass die einzelnen Hubvorrichtungen 12, 13 durch die Steuerung 19 oder eine getrennt dazu angeordnete Gesamtsteuerung erfasst wird und deren Position innerhalb des Hubsystems 11 bekannt ist.The number of lifting devices 12, 13 to be connected together to form a lifting system 11 is dependent on the load to be lifted, so that it is necessary for the monitoring of the lifting system 11, that the individual lifting devices 12, 13 by the controller 19 or a separately arranged Overall control is detected and their position within the lifting system 11 is known.

Damit die Anordnung und Positionierung der einzelnen Hubvorrichtungen 12, 13 vereinfacht und eine spezielle Reihenfolge für die nacheinander angeordneten Hubvorrichtungen 12, 13 nicht erforderlich wird, ermöglicht das erfindungsgemäße Verfahren zum Erfassen einer Konfiguration von mehreren Hubvorrichtungen 12, 13 in einem Hubsystem 11 eine einfache und bedienerfreundliche Handhabung, welches nachfolgend dargestellt wird:
Die Hubvorrichtungen 12, 13 werden entsprechend der anzuhebenden Last 14 positioniert. Im Anschluss werden die Versorgungsleitungen 21 zwischen den Hubvorrichtungen 12, 13 angebracht, um die Hubvorrichtungen 12, 13 in einer Reihe miteinander zu verbinden oder zu verketten. Anschließend wird die an einem offenen Ende vorgesehene Hubvorrichtung 12a mit einer Spannung versorgt. Die jeweiligen Steuerungen 19 der Hubvorrichtungen 12, 13 laufen hoch, und durch eine Steuerbeziehungsweise Busleitung in den Verbindungsleitungen 21 erfolgt eine Initialisierung der Steuerung 19. Anschließend wird an einer ersten Hubvorrichtung 12a ein Eingangspegel erkannt, der beispielsweise durch eine Brücke in der Verdrahtung realisiert ist. Dadurch definiert sich diese Hubvorrichtung 12a mit einer Knotenadresse 1 als Masterhubvorrichtung, so dass die weiteren in Reihe angeordneten Hubvorrichtungen 12, 13 abhängig von dieser ersten Hubvorrichtung 12a sind. Durch die Eigenbestimmung der ersten Hubvorrichtung 12a als Masterhubvorrichtung übernimmt diese die Steuerung für die weiteren Hubvorrichtungen 12, 13 sowie die Zuordnung zur Masterhubvorrichtung. Nachdem die Masterhubvorrichtung sich selbst definiert hat, wird ein Ausgang der Masterhubvorrichtung geschaltet, so dass ein Pegel am Eingang der nachfolgenden Hubvorrichtung 12b anliegt und eine Knotenadresse n + 1 generiert, da die Knotenadresse 1 bereits durch die Masterhubvorrichtung belegt ist. Nach der Generierung der Knotenadresse 2 für die Hubvorrichtung 12b schaltet die Steuerung 19 einen Ausgang der Steuerung 19 an der Hubvorrichtung 12b durch, so dass ein Eingangspegel wiederum an der nachfolgenden Hubvorrichtung 13b gemäß Figur 1 oder der Hubvorrichtung 12c gemäß Figur 2 anliegt. Es wird eine neue Knotenadresse generiert und anschließend der Ausgang der Steuerung 19 der Hubvorrichtung 13b oder 12c wieder durchgeschalten, so dass nach und nach die mit dem Verbindungsleitungen 21 verbundenen Hubvorrichtungen 12, 13 eine eindeutige Zuordnung von Knotenadressen erhalten. Durch eine Bus-Steuerung, welche die einzelnen Hubvorrichtungen 12, 13 miteinander verbindet, erkennt jede Steuerung 19 der Hubvorrichtung 12, 13, welche Knotenadresse die Hubvorrichtung 12, 13 selbst und welche Anzahl von Hubvorrichtungen 12, 13 das Hubsystem 11 bildet.Thus, the arrangement and positioning of the individual lifting devices 12, 13 simplified and a special order for successively arranged lifting devices 12, 13 is not required, the inventive method for detecting a configuration of several lifting devices 12, 13 in a lifting system 11 allows a simple and user-friendly Handling, which is shown below:
The lifting devices 12, 13 are positioned according to the load 14 to be lifted. Thereafter, the supply lines 21 are mounted between the elevators 12, 13 to connect or concatenate the elevators 12, 13 in a row. Subsequently, the provided at an open end lifting device 12a supplied with a voltage. The respective controls 19 of the lifting devices 12, 13 run high, and by a Steuerbeziehungsweise bus line in the connecting lines 21 is an initialization of the controller 19. Subsequently, an input level is detected at a first lifting device 12a, which is realized for example by a bridge in the wiring. As a result, this lifting device 12a defines itself with a node address 1 as the master lifting device, so that the further lifting devices 12, 13 arranged in series are dependent on this first lifting device 12a. By the self-determination of the first lifting device 12a as a master lifting device, this takes over the control for the further lifting devices 12, 13 and the assignment to the master lifting device. After the master lifting device has defined itself, an output of the master lifting device is switched so that a level is present at the input of the following lifting device 12b and generates a node address n + 1, since the node address 1 is already occupied by the master lifting device. After the generation of the node address 2 for the lifting device 12b, the controller 19 switches an output of the controller 19 on the lifting device 12b, so that an input level in turn on the following lifting device 13b according to FIG. 1 or the lifting device 12c according to FIG. 2 is applied. A new node address is generated and then the output of the controller 19 of the lifting device 13b or 12c switched through again, so that gradually connected to the connecting lines 21 lifting devices 12, 13 receive a unique assignment of node addresses. By a bus control, which connects the individual lifting devices 12, 13 together, each controller 19 recognizes the lifting device 12, 13, which node address the lifting device 12, 13 itself and which number of lifting devices 12, 13 forms the lifting system 11.

Das Ende der Zuordnung von Knotenadressen wird durch die letzte, am offenen Ende angeordnete Hubvorrichtung 13a erkannt. Über einen weiteren Eingangspegel erkennt die letzte Hubvorrichtung 13a, dass keine nachfolgende Hubvorrichtung 12, 13 im System mehr vorgesehen ist und gibt ein Signal an die Masterhubvorrichtung ab, und das Verfahren zum Erfassen der Konfiguration von Hubvorrichtungen 12, 13 im Hubsystem 11 wird beendet.The end of the assignment of node addresses is detected by the last, arranged at the open end lifting device 13a. Via a further input level, the last lifting device 13a recognizes that no subsequent lifting device 12, 13 is provided in the system any longer and outputs a signal to the master lifting device, and the method for detecting the configuration of lifting devices 12, 13 in the lifting system 11 is terminated.

Bei dem vorgenannten Verfahren sind alle Hubvorrichtungen 12, 13 gleich ausgebildet. Alternativ können zwei Arten von Hubvorrichtungen 12, 13 vorgesehen sein. Eine Art von Hubvorrichtungen 12, 13 umfasst bereits eine Energieversorgungsleitung, und die andere Art der Hubvorrichtungen ist ohne Energieversorgungsleitung ausgebildet. Die mit der Energieversorgungsleitung ausgebildeten Hubvorrichtungen 12, 13 werden zu Beginn einer Reihe der Hubvorrichtungen 12, 13 positioniert und als Masterhubvorrichtung initialisiert. Die weiteren Hubvorrichtungen 12, 13 sind sogenannte Slave-Hubvorrichtungen. Die mit Energieversorgungsleitungen versehenen Hubvorrichtungen, welche nicht als Masterhubvorrichtung initialisiert werden, können als Slave-Hubvorrichtungen eingesetzt werden, mit dem Vorteil, dass darüber eine Energieeinspeisung nach einer vorbestimmten Anzahl von Slave-Hubvorrichtungen ermöglicht ist.In the aforementioned method, all lifting devices 12, 13 are the same. Alternatively, two types of lifting devices 12, 13 may be provided. One type of lifting devices 12, 13 already comprises a power supply line, and the other type of lifting devices is designed without a power supply line. The lifting devices 12, 13 formed with the power supply line are positioned at the beginning of a row of the lifting devices 12, 13 and initialized as a master lifting device. The further lifting devices 12, 13 are so-called slave lifting devices. The power supply line provided lifting devices, which are not initialized as a master lifting device, can be used as slave lifting devices, with the advantage of enabling energy input after a predetermined number of slave lifting devices.

Nach der vollständigen Generierung von Knotenadressen für die jeweiligen Hubvorrichtungen 12, 13 werden die Hubvorrichtungen 12, 13, die einander gegenüberstehen, paarweise einander zugeordnet, so dass beim Heben und Senken eine paarweise Ansteuerung der Hubvorrichtungen 12a und 13a, 12b und 13b ermöglicht ist. Gleichzeitig ist durch die Steuerung ermöglicht, dass ein oder mehrere Paare ausgewählt werden, die gleichzeitig den Hebe- und Senkvorgang durchführen.After the complete generation of node addresses for the respective lifting devices 12, 13, the lifting devices 12, 13, which face each other, in pairs associated with each other, so that when lifting and lowering a pair of actuation of the lifting devices 12a and 13a, 12b and 13b is possible. At the same time, the control allows one or more pairs to be selected which simultaneously perform the lifting and lowering operations.

Durch dieses Verfahren zum Erfassen einer Konfiguration eines Hubsystems 11 ist des Weiteren ermöglicht, dass von jeder Steuerung 19 der Hubvorrichtung 12, 13 das Gesamtsystem oder einzelne Hubvorrichtungen 12, 13 steuerbar sind, sowie die paar- oder gruppenweise Ansteuerung der Hubvorrichtungen 12, 13 ermöglicht wird.By means of this method for detecting a configuration of a lifting system 11, it is further possible for each control 19 of the lifting device 12, 13 to control the entire system or individual lifting devices 12, 13, and to enable the lifting devices 12, 13 to be actuated in pairs or groups ,

Zusätzlich kann jede Steuerung 19 bei einem auftretenden Fehler eine Fehlermeldung ausgeben und anzeigen, welche der Hubvorrichtungen 12, 13 die Fehlermeldung ausgegeben hat. Dadurch ist ein flexibles Hubsystem 11 geschaffen, das im Aufstellen bedienfreundlich ist und gleichzeitig einen hohen Überwachungsgrad und somit Sicherheit beim Betrieb des Hubsystems 11 ermöglicht.In addition, each controller 19 can output an error message when an error occurs and indicate which of the lifting devices 12, 13 has output the error message. As a result, a flexible lifting system 11 is created, which is easy to set up and at the same time a high degree of monitoring and thus security in the operation of the lifting system 11 allows.

In Figur 3 ist schematisch ein Display 23 einer Steuerung 19 dargestellt. Nach der Konfiguration des Hubsystems 11 erscheinen auf dem Display 23 Symbole, die sowohl auf die Anzahl der im Hubsystem 11 sich befindenden Hubvorrichtungen 12, 13 hinweist, als auch die paarweise Zuordnung signalisiert. Beispielsweise wird einem ersten Hebepaar der Buchstabe A, einem zweiten Hebepaar der Buchstabe B usw. zugeordnet. Durch die Darstellung eines Großbuchstabens wird signalisiert, dass diese Hebevorrichtung 12, 13 bzw. das Hebepaar A aktiviert ist. Eine Darstellung in Form eines Kleinbuchstabens zeigt, dass diese Hubvorrichtungen 12, 13, wie beispielsweise das Hebepaar c und d nicht aktiviert ist. Alternativ können verschiedentliche Symbole zu dieser Kennzeichnung vorgesehen sein. Es kann auch eine Kombination von zwei Symbolen oder eine farbliche Darstellung ermöglicht sein, um sowohl die paarweise Zuordnung als auch die Aktivierung bzw. Nichtaktivierung der Hubvorrichtungen 12, 13 darzustellen. Zusätzlich kann bei einer Fehlermeldung unmittelbar ein Text zur Fehlermeldung erscheinen oder aber die einzelne Hubvorrichtung 12, 13, welche beispielsweise mit einem Buchstaben gekennzeichnet ist, mit einer bestimmten Farbe hinterlegt und/oder der Buchstabe farblich verändert sein.In FIG. 3 schematically a display 23 of a controller 19 is shown. After the configuration of the lifting system 11 23 symbols appear on the display, which points both to the number of lifting devices 12, 13 located in the lifting system 11, as well as signals the pairwise assignment. For example, a first pair of hips the letter A, a second pair of hips the letter B, etc. assigned. By the representation of a capital letter is signaled that this lifting device 12, 13 and the lifting pair A is activated. A representation in the form of a lowercase letter shows that these lifting devices 12, 13, such as the lifting pair c and d is not activated. Alternatively, various symbols may be provided for this identification. Also, a combination of two symbols or a color representation may be enabled to illustrate both the pairwise association and the activation or non-activation of the elevators 12, 13. In addition, in the case of an error message, a text may immediately appear for the error message or else the individual lifting device 12, 13, which is marked with a letter for example, may be deposited with a specific color and / or the letter may be changed in color.
