Abstract

The invention relates to an arrangement for transmitting control signals from a transmitter (4, 4'; 5, 5') via control lines (1) to actuators of a crane system (6, 6'; 7, 7') as receivers. In this arrangement, the control signals are addressed in a coder on the transmitter side (for example suspended key control (2)). At the receiver end (for example trolley (7, 7'), crane (6, 6'), tandem crane and so forth), there is a decoder which allocates the incoming control signals to the respective actuators. In this manner, only a small number of lines is now needed for the entire transmission path between transmitter (4, 4'; 5, 5') and receiver (6, 6'; 7, 7'). <IMAGE>

Description

Technisches Gebiet:Technical field:

Die Erfindung betrifft eine Anordnung zur Übertragung von Steuersignalen von einem Sender über Steuerleitungen nach Stellgliedern einer Krananlage als Empfänger.The invention relates to an arrangement for transmitting control signals from a transmitter via control lines to actuators of a crane system as a receiver.

Stand der Technik:State of the art:

Damit Steuersignale von einem Sender, z.B. von einem Hängetaster, über Leitungen nach Stellgliedern einer Krananlage, z.B. Katze, Kran, Tandemkran, als Empfänger übertragen werden können, werden Schleifleitungen oder Kabelschlepps eingesetzt. Abhängig von der Zahl der Stellglieder innerhalb des Kransystems werden dabei häufig vierzehn und mehr voneinander getrennte Steuerleitungen benötigt.So that control signals can be transmitted from a transmitter, for example from a pendant control, via lines to actuators of a crane system, for example a cat, crane, tandem crane, as a receiver, conductor lines or cable tows are used. Depending on the number of actuators within the crane system, fourteen or more separate control lines are often required.

Darstellung der Erfindung:Presentation of the invention:

Hier will die Erfindung Abhilfe schaffen. Die in den Patentansprüchen beschriebene Erfindung löst die Aufgabe, bei einer Anordnung der eingangs genannten Art die Zahl der Steuerleitungen wesentlich zu vermindern.The invention seeks to remedy this. The invention described in the claims solves the problem of substantially reducing the number of control lines in an arrangement of the type mentioned at the outset.

Bei der Erfindung erfolgt auf der Senderseite - Hängetaster - in einem Coder die Adressierung der Steuersignale. Auf der Empfängerseite - Katze, Kran, Tandemkran - ist ein Decoder vorhanden, der das ankommende Steuersignal dem jeweiligen Stellglied zuordnet. Es wird für den gesamten Übertragungsweg zwischen Sender umd Empfänger nur noch eine geringe Anzahl von Leitungen benötigt.In the invention, the control signals are addressed in a coder on the transmitter side - pendant control. On the receiver side - cat, crane, tandem crane - there is a decoder that assigns the incoming control signal to the respective actuator. Only a small number of lines are required for the entire transmission path between the transmitter and the receiver.

In Ausgestaltung der Erfindung ist ein bidirektionaler Übertragungsbus so definiert, daß an ihn an beliebiger Stelle ein Sender bzw. Empfänger angebracht werden kann. Die Zuordnung des Senders zu dem Empfänger geschieht über einstellbare Adressen. Soll ein Tandemkran mit einer derartigen Anordnung ausgerüstet werden, so lassen sich auch zwei und mehr Empfänger einem Sender zuordnen.In one embodiment of the invention, a bidirectional transmission bus is defined such that a transmitter or receiver can be attached to it at any point. The sender is assigned to the receiver via adjustable addresses. If a tandem crane is to be equipped with such an arrangement, two or more receivers can also be assigned to one transmitter.

In Weiterbildung der Erfindung ist bei der Anordnung eine Automobile Bitserielle Universal-Schnittstelle - ABUS - verwendet. Ein solcher ABUS ist an sich bekannt (Beil/Pelz "Eine Bitserielle Universal-Schnittstelle..." in DE-Zeitschrift "Elektronik" vom 17.02.1989 S. 102 bis 105).In a further development of the invention, an automobile bit serial universal interface - ABUS - is used in the arrangement. Such an ABUS is known per se (Beil / Pelz "A bit serial universal interface ..." in DE magazine "Electronics" from February 17th, 1989, pp. 102 to 105).

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden nachfolgend im einzelnen beschrieben. Es zeigen

Fig. 1
die schematische Darstellung einer Einfachkransteuerung;
Fig. 2
die schematische Darstellung einer Tandemkransteuerung.
Two embodiments of the invention are shown in the drawing and are described in detail below. Show it
Fig. 1
the schematic representation of a single crane control;
Fig. 2
the schematic representation of a tandem crane control.

Bester Weg zur Ausführung der Erfindung:Best way to carry out the invention:

An eine als Steuerleitung dienende Stromschiene oder Schleppleitung 1 ist senderseitig ein Hängetaster 2 angeschlossen. Die Verbindung zwischen dem Hängetaster 2 nach der Stromschiene 1 erfolgt über Anschlußleitungen 3. In dem Hängetaster 2 sind zwei Sender 4, 5 parallel geschaltet; d.h. jeder der Sender 4, 5 ist parallel zu dem anderen mit den Anschlußleitungen 3 verbunden. In jedem der Sender 4, 5 erfolgt durch Betätigung einer der Tasten T die Ausgabe eines Befehls. Empfängerseitig sind an die Stromschiene 1 ein Kran 6 sowie eine Laufkatze 7 angeschlossen. Der Empfänger 12 in der Laufkatze 7 ist über Anschlußleitungen 8 mit der Stromschiene 1 verbunden. In dem Kran 6 ist ein Empfänger 11 vorgesehen, der über Anschlußleitungen 13 mit der Stromschiene 1 verbunden ist.A pendant control 2 is connected on the transmitter side to a busbar or trailing line 1 serving as a control line. The connection between the pendant button 2 after the busbar 1 is made via connecting lines 3. In the pendant button 2, two transmitters 4, 5 are connected in parallel; i.e. each of the transmitters 4, 5 is connected to the connecting lines 3 in parallel with the other. In each of the transmitters 4, 5, by pressing one of the buttons T, a command is issued. A crane 6 and a trolley 7 are connected to the conductor rail 1 on the receiver side. The receiver 12 in the trolley 7 is connected to the busbar 1 via connecting lines 8. In the crane 6, a receiver 11 is provided, which is connected to the busbar 1 via connecting lines 13.

Bei der in Fig. 1 dargestellten Einfachkransteuerung sind die vorgenannten Bauelemente jeweils einmal vorgesehen. Bei der in Fig. 2 dargestellten Tandemkransteuerung sind alle Emlemente doppelt vorgesehen; sie sind sämtlich an die Stromschiene 1 angeschlossen. Die jeweils zweiten Elemente sind durch einen Apostroph (') gekennzeichnet.In the single crane control system shown in FIG. 1, the aforementioned components are each provided once. In the tandem crane control system shown in FIG. 2, all elements are provided twice; they are all connected to the busbar 1. The second elements are identified by an apostrophe (').

Die Steuersignale werden in den Hängetaster 1, 1' codiert. Es wird nur noch eine aus zwei Leitungen bestehende Stromschiene oder Schleppleitung 1 für den gesamten Übertragungsweg benötigt, da auf der Empfängerseite, nämlich in dem Kran 6, 6' und der Laufkatze 7, 7', Decoder vergesehen sind. Es ist ein bidirektionaler Übertragungsbus so definiert, daß an diesen Bus an beliebiger Stelle Sender - Hängetaster 2, 2' - oder Empfänger - Krane 6, 6'; Laufkatzen 7, 7' - angebracht werden können. Die Zuordnung der Hängetater 2, 2' zu den Kranen 6, 6' bzw. den Laufkatzen 7, 7' geschieht über einstellbare Adressen.The control signals are encoded in the pendant button 1, 1 '. Only a busbar or trailing line 1 consisting of two lines is required for the entire transmission path, since decoders are provided on the receiver side, namely in the crane 6, 6 'and the trolley 7, 7'. A bidirectional transmission bus is defined in such a way that transmitter - pendant buttons 2, 2 'or receiver cranes 6, 6'; Trolleys 7, 7 '- can be attached. The assignment of the hangers 2, 2 'to the cranes 6, 6' or the trolleys 7, 7 'is done via adjustable addresses.

Anstelle der Sender können auch Empfänger vorgesehen sein, anstelle der Empfänger Sender, und zwar jeweils eine beliebige - n - Anzahl.Instead of the transmitters, receivers can also be provided, instead of the receivers transmitters, in each case an arbitrary number of n.

Bevorzugt wird als Anordnung für die Übertragung der Steuersignale ein ABUS-Netzwerk. Ein ABUS-Netzwerk besteht aus einer Busleitung und mehreren an die Busleitung angeschlossenen Teilnehmern. Die Anzahl der angeschlossenen Teilnehmer und die Länge der Busleitung sind nur durch die zur Verfügung stehende Leistung der Bustreiber und die Busauslastung begrenzt. Als Interface zwischen Teilnehmer und Busleitung dient ein IC. Jeder dieser ICs ist mit einem Sende- und Empfangsteil über getrennte Leitungen an den Bus angeschlossen. Die Vorgänge auf der ABUS-Leitung werden vom Empfangsteil jeder ICs ständig überwacht, um einerseits Nachrichten einzulesen und andererseits die vom eigenen Sendeteil stammenden Nachrichten auf Fehlerfreiheit zu überprüfen.An ABUS network is preferred as an arrangement for the transmission of the control signals. An ABUS network consists of a bus line and several participants connected to the bus line. The number of connected participants and the length of the bus line are only limited by the available power of the bus driver and the bus load. An IC serves as the interface between the subscriber and the bus line. Each of these ICs is connected to the bus with a transmitting and receiving part via separate lines. The processes on the ABUS line are constantly monitored by the receiving section of each IC, in order to read messages on the one hand and to check that the messages from the own sending section are error-free.

Die Nachrichtenübertragung erfolgt nach einem festen Protokoll. Es können sowohl Befehle als auch Daten übertragen werden. Jedes Telegramm enthält als erste Information eine Kennung. Die Kennung dient der Unterscheidung zwischen Befehlen und Daten, der Datenkennzeichnung und der Prioritätssteuerung.The messages are transmitted according to a fixed protocol. Both commands and data can be transmitted. Each telegram contains an identifier as the first piece of information. The identifier is used to distinguish between commands and data, data identification and priority control.

Das IC ist in drei Funktionsblöcke eingeteilt: Eine Mikroprossessor-Schnittstelle, einen Speicher und eine ABUS-Steuerlogik.The IC is divided into three function blocks: a microprocessor interface, a memory and an ABUS control logic.

Weitere Einzelheiten über die Bitserielle Universal-Schnittstelle - ABUS - sind dem eingangs genannten Aufsatz von Beil/Pelz zu entnehmen.Further details on the bit serial universal interface - ABUS - can be found in the article by Beil / Pelz mentioned at the beginning.

Gewerbliche Verwertbarkeit:Commercial usability:

Die Erfindung ist bei allen Krananlagen verwendbar, bei denen die Steuersignale von einem Sender nach einem Empfänger über Steuerleitungen übertragen werden.The invention can be used in all crane systems in which the control signals are transmitted from a transmitter to a receiver via control lines.
