Description

Die Erfindung betrifft ein Verfahren zum Bedienen eines Fernsteuerungssystems sowie ein derartiges Fernsteuerungssystem.The invention relates to a method for operating a remote control system and such a remote control system.

Die DE 10 2007 003 161 A1 offenbart eine Fernbedienung, eine Fernbedienung-Konfigurationsdatei-Erzeugungseinheit, ein fernbedienbares Gerät, einen Fernbedienung-Konfigurationsdatei-Erzeuger, ein Verfahren zum Ermitteln einer Konfiguration einer Fernbedienung, ein Verfahren zum Erzeugen einer Fernbedienung-Konfigurationsdatei und ein Verfahren zum Fernbedienen eines fernbedienbaren Geräts.The DE 10 2007 003 161 A1 discloses a remote control, a remote control configuration file generating unit, a remote-controlled device, a remote control configuration file generator, a method for determining a configuration of a remote control, a method for generating a remote control configuration file, and a method for remotely controlling a remote-controlled device.

Arbeitsmaschinen, die mittels eines Fernsteuerungssystems bedient werden können, sind seit längerem bekannt. Eine Arbeitsmaschine umfasst eine Vielzahl an Komponenten und Stelleinheiten, die mittels des Fernsteuerungssystems betätigt werden können. Aufgrund der Komplexität der Arbeitsmaschine ist das Bedienen des Fernsteuerungssystems mittels einer Bedieneinheit kompliziert. Die Bedieneinheit erfordert insbesondere bei einer komplexen Arbeitsmaschine eine Vielzahl von Anzeigen und Bedienelementen. Ein Bedienelement kann beispielsweise ein Taster, ein Schalter, ein Steuerhebel oder ein Drehschalter sein. Um die Anzahl der Bedienelemente an der Bedieneinheit zu reduzieren, kann ein Bildschirm in der Bedieneinheit verwendet werden. Ein Bildschirm ermöglicht mittels mehrerer Bedienmenüs, insbesondere mit wechselnden Symbolen und/oder Anzeigen, einer reduzierten Anzahl von Bedienelementen mehrere Funktionen zuzuweisen. Dadurch kann eine erhöhte Funktionsdichte erreicht werden. Die erhöhte Funktionsdicht führt aber zu einem erhöhten Bedienaufwand für einen Bediener. Insbesondere ist es nachteilig, dass der Bediener durch eine erhöhte Anzahl von Bedienmenüs navigieren muss. Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Verfahren zum Bedienen eines Fernsteuerungssystems derart zu verbessern, dass die Bedienung vereinfacht ist.Work machines that can be operated by means of a remote control system have long been known. A work machine includes a plurality of components and actuators that can be operated by the remote control system. Due to the complexity of the work machine, the operation of the remote control system by means of a control unit is complicated. The operating unit requires a large number of displays and operating elements, in particular in the case of a complex work machine. An operating element may be, for example, a button, a switch, a control lever or a rotary switch. In order to reduce the number of operating elements on the operating unit, a screen can be used in the operating unit. A screen makes it possible to use a plurality of operating menus, in particular with changing symbols and / or displays, a reduced number of operating elements more Assign functions. As a result, an increased functional density can be achieved. However, the increased functional density leads to an increased operating effort for an operator. In particular, it is disadvantageous that the operator must navigate through an increased number of operating menus. It is therefore an object of the present invention to improve a method of operating a remote control system such that the operation is simplified.

Diese Aufgabe wird durch ein Verfahren mit den im Anspruch 1 angegebenen Merkmalen gelöst.This object is achieved by a method having the features specified in claim 1.

Erfindungsgemäß wurde erkannt, dass es möglich ist, die Anzahl an Bedien- und Auswahlmenüs, die mittels einer Anzeige einer Bedieneinheit eines Fernsteuerungssystems einem Bediener angezeigt werden, zu reduzieren. Dazu dient ein Selektieren mindestens eines Bedien- und Auswahlmenüs in Abhängigkeit einer Arbeitsmaschinen-Ist-Konfiguration. In Abhängigkeit der Arbeitsmaschinen-Ist-Konfiguration wird also die Navigationsmöglichkeit zwischen den Bedien- und Auswahlmenüs sinnvoll reduziert, indem eine Vorselektion sinnvoller Menüs durchgeführt wird. Insbesondere erfolgt die Vorselektion automatisch. Die Arbeitsmaschinen-Ist-Konfiguration wird mittels einer Steuerungseinheit der Arbeitsmaschine erfasst. Die Steuerungseinheit steht mit einer Kommunikationseinheit in Kommunikationsverbindung. Die Kommunikationseinheit ist Bestandteil des Fernsteuerungssystems und dient zur Kommunikation mit der Bedieneinheit. Die Bedieneinheit ist insbesondere kabellos mit der Kommunikationseinheit verbunden. Dies kann beispielsweise durch Funk erfolgen. Es sind auch andere kabellose Signalübertragungsmöglichkeiten denkbar wie Bluetooth. Die Kommunikationseinheit ist insbesondere direkt in der damit zu bedienenden Arbeitsmaschine angeordnet. Die Kommunikationseinheit ist beispielsweise kabelgebunden mit der Steuerungseinheit verbunden. Durch das Selektieren wird die Anzahl der mittels der Anzeige an der Bedieneinheit angezeigten Bedien- und Auswahlmenüs reduziert. Insbesondere steuert die Steuerungseinheit neben den Funktionen der Arbeitsmaschine auch die Darstellung der Bedien- und Auswahlmenüs auf der Bedien-Einheit. Eine Bedieneinheit-Ist-Konfiguration weist eine Bedieneinheit-Ist-Menüstruktur auf, die durch die Bedien- und Auswahlmenüs gebildet ist. Durch Selektieren und Übermitteln der Bedien- und Auswahlmenüs an die Bedieneinheit kann die Bedieneinheit-Ist-Menüstruktur der Bedieneinheit gezielt verändert werden. Das Verändern der Bedieneinheit-Ist-Menüstruktur ist dadurch vereinfacht. Das erfindungsgemäße Verfahren ermöglicht also nicht nur eine individualisierte Tastenbelegung einer Fernbedienung, sondern ermöglicht gezielt eine Anpassung einer Struktur verschiedener Menüs. Jedes Menü, beispielsweise Bedienmenüs und/oder Auswahlmenüs, ist zur Handhabung des Fernsteuerungssystems geeignet. Die Handhabung des Fernsteuerungssystems und die Bedienung der Arbeitsmaschine sind vereinfacht. Insbesondere ist es nicht erforderlich, dass ein Bediener selbst, also manuell, eine komplexe Menüsteuerung an der Bedieneinheit übernehmen muss. Es ist insbesondere nicht erforderlich, dass der Bediener die Anzahl der Bedien- und Auswahlmenüs reduziert und insbesondere nicht erforderliche Bedien- und Auswahlmenüs abwählt. Dem Bediener wird die Navigation durch die relevanten Bedien- und Anzeigemenüs abgenommen. Insbesondere wird die Anzahl der Arbeitsschritte, die der Bediener durchführen muss, reduziert. Ein derartiges Verfahren ist effektiv und daher kostengünstig. Ein derartiges Verfahren ist weniger fehleranfällig. Insbesondere ist eine Fehlnavigation durch den Bediener, also das Anwählen nicht relevanter Bedien- und Auswahlmenüs, ausgeschlossen. Das Verfahren ermöglicht die Bedienung einer Arbeitsmaschine mit einer erhöhten Sicherheit. Das Selektieren erfolgt insbesondere in der Steuerungseinheit der Arbeitsmaschine. Insbesondere wird durch das Selektieren die Anzahl der von einem Bediener anwählbaren Bedien- und Anzeigemenüs auf eine Anzahl relevanter Bedien- und Anzeigemenüs reduziert. Nicht relevante Bedien- und Anzeigemenüs werden nicht angezeigt. Dadurch wird die Übersichtlichkeit der Anzeige der Bedieneinheit für den Bediener erhöht. Dadurch, dass ausschließlich die relevanten Bedien- und Anzeigemenüs dargestellt werden, könnte diese schneller und direkter angewählt werden. Dies kann beispielsweise direkt nach dem Einschalten der Fernsteuerung erfolgen, ohne dass der Bediener eine Reihe von nicht relevanten Bedien- und Anzeigemenüs durchnavigieren muss. Das Verfahren ermöglicht eine Handhabung der Arbeitsmaschine mit verbesserter Wirtschaftlichkeit. Das erfindungsgemäße Verfahren ermöglicht insbesondere die Verwendung ein und derselben Fernsteuerung in Arbeitsmaschinen unterschiedlicher Typen. Insbesondere ist es nicht erforderlich, dass die Fernsteuerung typenabhängig programmiert oder parametriert werden muss. Die Verwendung ein und derselben Fernsteuerung in unterschiedlichen Arbeitsmaschinen ist dadurch vereinfacht. Zusätzliche Arbeitsschritte für die Anpassung der Fernsteuerung an verschiedene Arbeitsmaschinen sind nicht erforderlich.According to the invention, it has been recognized that it is possible to reduce the number of operating and selection menus that are displayed to an operator by means of a display of a control unit of a remote control system. This is done by selecting at least one operating and selection menu depending on a working machine-actual configuration. Depending on the working machine-actual configuration, the navigation possibility between the operating and selection menus is meaningfully reduced by carrying out a preselection of useful menus. In particular, the preselection is done automatically. The working machine actual configuration is detected by means of a control unit of the working machine. The control unit is in communication with a communication unit. The communication unit is part of the remote control system and serves for communication with the operating unit. The operating unit is in particular wirelessly connected to the communication unit. This can be done for example by radio. There are also other wireless signal transmission options conceivable as Bluetooth. The communication unit is in particular arranged directly in the machine to be operated therewith. The communication unit is connected, for example, wired to the control unit. Selecting reduces the number of operating and selection menus displayed by the display on the control panel. In particular, in addition to the functions of the working machine, the control unit also controls the representation of the operating and selection menus on the operating unit. An operation unit-actual configuration has an operation unit-actual menu structure formed by the operation and selection menus. By selecting and transmitting the operating and selection menus to the operating unit, the operating unit-actual menu structure of the operating unit can be specifically changed. Changing the operating unit-actual menu structure is thereby simplified. Thus, the method according to the invention not only allows an individualized key assignment of a remote control, but also makes it possible to adapt a structure of different menus. Each menu, such as operating menus and / or selection menus, is suitable for handling the remote control system. The handling of the remote control system and the operation of the working machine are simplified. In particular, it is not necessary for an operator himself, ie manually, to undertake a complex menu control on the operating unit. In particular, it is not necessary for the operator to reduce the number of operating and selection menus and, in particular, to deselect unnecessary operating and selection menus. The operator is taken off the navigation through the relevant operating and display menus. In particular, the number of operations that the operator must perform is reduced. Such a method is effective and therefore inexpensive. Such a method is less error prone. In particular, a false navigation by the operator, ie the selection of non-relevant operating and selection menus, excluded. The method allows the operation of a work machine with increased security. The selection takes place in particular in the control unit of the working machine. In particular, the number is selected by an operator by selecting selectable operating and display menus are reduced to a number of relevant operating and display menus.

The fact that only the relevant operating and display menus are displayed, this could be selected faster and more direct. This can be done, for example, directly after switching on the remote control, without the operator having to navigate through a series of irrelevant operating and display menus. The method allows handling of the work machine with improved efficiency. In particular, the method according to the invention makes it possible to use one and the same remote control in machines of different types. In particular, it is not necessary that the remote control must be programmed or parameterized depending on the type. The use of one and the same remote control in different machines is thereby simplified. Additional work steps for the adjustment of the remote control to different machines are not required.

Ein Verfahren nach Anspruch 2 ermöglicht eine umfassende Erfassung einer Ist-Konfiguration der Bedieneinheit. Neben einem Inhalt der Anzeige selbst wird auch ein Zustand des mindestens einen Bedienelements erfasst. Ein Bedienelement kann beispielsweise ein Taster, ein Schalter, ein Steuerhebel oder ein Drehschalter sein. Der jeweilige Zustand gibt an, in welcher Stellung sich der jeweilige Taster, Schalter, Steuerhebel oder Drehschalter befindet.A method according to claim 2 enables a comprehensive detection of an actual configuration of the operating unit. In addition to a content of the display itself, a state of the at least one operating element is detected. An operating element may be, for example, a button, a switch, a control lever or a rotary switch. The respective state indicates in which position the respective button, switch, control lever or rotary switch is located.

Ein Verfahren nach Anspruch 3 ist komfortabel. Insbesondere ist es nicht erforderlich, dass der Bediener auf etwaige Änderungen der Arbeitsmaschine reagiert. Das Selektieren erfolgt zumindest teilautomatisiert und insbesondere vollautomatisch.A method according to claim 3 is convenient. In particular, it is not necessary for the operator to be aware of any changes in the Working machine reacts. The selection is carried out at least partially automated and in particular fully automatic.

Ein Verfahren nach Anspruch 4 ermöglicht eine effektive Durchführung des Verfahrens. Dadurch, dass die Bedieneinheit-Ist-Konfiguration an die Steuerungseinheit übermittelt wird und gleichzeitig in der Steuerungseinheit die Arbeitsmaschinen-Ist-Konfiguration erfasst wird, kann dort direkt das Selektieren erfolgen. Weitere Signalübertragungen sind nicht erforderlich.A method according to claim 4 enables effective implementation of the method. Characterized in that the control unit-actual configuration is transmitted to the control unit and at the same time in the control unit, the working machine actual configuration is detected, there can be made directly selecting.

Ein Verfahren nach Anspruch 9 dient zur Berücksichtigung wesentlicher Kriterien der Arbeitsmaschine. Ein darauf gerichtetes, optimiertes Bedien- und Anzeigemenü ermöglicht eine vereinfachte und direkte Handhabung für den Bediener.A method according to claim 9 serves to take into account essential criteria of the working machine. An optimized, optimized operating and display menu allows a simplified and direct handling for the operator.

Ein Verfahren nach Anspruch 10 ermöglicht einem Bediener eine situationsangepasste, aktualisierte Darstellung des Bedien- und Anzeigemenüs. Insbesondere zeitlich ändernde Zustände beispielsweise der Arbeitsmaschine werden direkt erfasst und beim Selektieren der Bedien- und Anzeigemenüs berücksichtigt.A method according to claim 10 allows an operator a situation-adapted, updated representation of the control and display menus. In particular temporally changing states, for example the Work machines are recorded directly and taken into account when selecting the operating and display menus.

Ein Fernsteuerungssystem kann eine Bedieneinheit und eine damit in Kommunikationsverbindung stehende Kommunikationseinheit aufweisen. Die Kommunikationseinheit dient zum Verbinden mit der Steuerungseinheit der Arbeitsmaschine. Dazu weist die Kommunikationseinheit eine Schnittstelle auf, die als eine Standard-Schnittstelle ausgeführt ist. Dadurch ist es insbesondere möglich, das Fernsteuerungssystem über die Kommunikationseinheit mit Steuerungseinheiten verschiedener Arbeitsmaschinen zu verbinden. Ein derartiges Fernsteuerungssystem ist flexibel und universell einsetzbar. Insbesondere ist es denkbar, dass ein und dasselbe Fernsteuerungssystem zum ferngesteuerten Bedienen verschiedener Arbeitsmaschinen eingesetzt wird. Dadurch, dass die Schnittstelle eine Standard-Schnittstelle ist, ist das Verbinden mit der jeweiligen Steuerungseinheit schnell und unkompliziert möglich. Die Standard-Schnittstelle ist robust und erfordert eine unkomplizierte und zuverlässige Verbindung der Bedieneinheit mit der Steuerungseinheit. Als Standardschnittstelle kann beispielsweise ein Datenbus, insbesondere ein Controller Area Network (CAN)-Bus oder eine Ethernet-Schnittstelle dienen.A remote control system may include an operating unit and a communication unit in communication therewith. The communication unit is used to connect to the control unit of the work machine. For this purpose, the communication unit has an interface which is designed as a standard interface. This makes it possible in particular to connect the remote control system via the communication unit with control units of various work machines. Such a remote control system is flexible and universally applicable. In particular, it is conceivable that one and the same remote control system is used for the remote-controlled operation of various work machines. Because the interface is a standard interface, the connection with the respective control unit is possible quickly and easily. The standard interface is robust and requires an uncomplicated and reliable connection of the operating unit with the control unit. For example, a data bus, in particular a Controller Area Network (CAN) bus or an Ethernet interface, can serve as the standard interface.

Ein Fernsteuerungssystem kann ein Bedienelement mit einer erhöhten Übersichtlichkeit aufweisen. Dadurch, dass das Bedienelement in die Anzeige der Bedieneinheit integriert ist, kann auf der Anzeige das Bedienelement grafisch symbolhaft und als Schaltfläche insbesondere mittels eines Berührbildschirms, der auch Touchscreen genannt wird, dargestellt werden.A remote control system may include a control with increased clarity. Because the operating element is integrated in the display of the operating unit, the operating element can be represented on the display graphically symbolically and as a button, in particular by means of a touch screen, which is also called a touch screen.

Das Fernsteuerungssystem 1 umfasst eine Bedieneinheit 3 und eine Kommunikationseinheit 4, die mit der Bedieneinheit 3 in Kommunikationsverbindung steht. Die Kommunikationsverbindung ist kabellos, beispielsweise mittels einer Funkverbindung. Die Kommunikationsverbindung ist bidirektional und ermöglicht eine Kommunikation von der Bedieneinheit 3 zu der Kommunikationseinheit 4 und umgekehrt. Die Kommunikationseinheit 4 ist in der Arbeitsmaschine 2 angeordnet und insbesondere in der Arbeitsmaschine 2 integriert. Es ist auch möglich, dass die Kommunikationseinheit 4 extern an der Arbeitsmaschine 2 angeordnet ist.The remote control system 1 comprises an operating unit 3 and a communication unit 4, which communicates with the operating unit 3 in communication. The communication connection is wireless, for example by means of a radio link. The communication link is bidirectional and enables communication from the operating unit 3 to the communication unit 4 and vice versa. The communication unit 4 is arranged in the work machine 2 and integrated in particular in the work machine 2. It is also possible that the communication unit 4 is arranged externally on the work machine 2.

Die Bedieneinheit 3 umfast eine Anzeige 5 in Form eines Bildschirms oder eines Displays. Weiterhin umfasst die Bedieneinheit 3 mehrere, gemäß dem gezeigten Ausführungsbeispiel zehn, Bedienelemente 6 in Form von Schaltern. Die Bedienelemente 6 dienen zum Bedienen der Bedieneinheit und insbesondere zum Auslösen einer Aktion. Die Bedienelemente 6 korrespondieren mit symbolhaften Schaltflächen 7 auf der Anzeige 5. Die Schaltflächen 7 zeigen die jeweilige Konfiguration der Bedienelemente 6, insbesondere die jeweilige Stellung eines Schalters, an. Es ist auch möglich, dass die Anzeige 5 als Berührbildschirm ausgeführt ist. In diesem Fall können die Bedienelemente 6 in dem Berührbildschirm integriert sein, so dass durch Berühren des Berührbildschirms die Bedienelemente 6 bedient werden können. Das Risiko eines unbeabsichtigten Betätigens eines Bedienelements 6 ist dadurch reduziert.The operating unit 3 comprises a display 5 in the form of a screen or a display. Furthermore, the operating unit 3 comprises several, according to the embodiment shown ten, controls 6 in the form of switches. The controls 6 are used to operate the control unit and in particular to trigger an action. The controls 6 correspond with symbolic buttons 7 on the display 5.

In this case, the operating elements 6 may be integrated in the touch screen, so that the operating elements 6 can be operated by touching the touch screen. The risk of unintentional actuation of a control element 6 is thereby reduced.

Die Kommunikationseinheit 4 steht in Kommunikationsverbindung mit einer Steuerungseinheit 8 der Arbeitsmaschine 2. Die Kommunikationsverbindung ist insbesondere kabelgebunden und beispielsweise durch einen Daten-Bus ausgeführt. Die Kommunikationsverbindung ist bidirektional. Die Kommunikationsverbindung ermöglicht eine Datenübertragung von der Kommunikationseinheit 4 zu der Steuerungseinheit 8 und umgekehrt.The communication unit 4 is in communication with a control unit 8 of the work machine 2. The communication connection is in particular wired and executed, for example, by a data bus. The communication connection is bidirectional. The communication connection enables data transmission from the communication unit 4 to the control unit 8 and vice versa.

Die Steuerungseinheit 8 steht mit verschiedenen Komponenten 9 der Arbeitsmaschine 2 in Signalverbindung. Gemäß dem gezeigten Ausführungsbeispiel sind fünf Komponenten 9 vorgesehen. Es können auch mehr oder weniger als fünf Komponenten 9 mit der Steuerungseinheit 8 in Signalverbindung stehen. Als Komponenten 9 können beispielsweise Sensoren der Arbeitsmaschine 2, wie beispielsweise Temperatur-, Druck-, Geschwindigkeits- oder andere Sensoren dienen. Die Komponenten 9 können auch als manuelle Schalter ausgeführt sein. Durch die Signalverbindung der Komponenten 9 mit der Steuerungseinheit 8 werden die jeweils aktuellen Zustände der Komponenten 9 an die Steuerungseinheit 8 übertragen. Es ist auch möglich, eine Signalverbindung von der Steuerungseinheit 8 zu mindestens einer der Komponenten 9 zu ermöglichen, um den jeweiligen, aktuellen Zustand der Komponenten 9 direkt durch die Steuerungseinheit 8 zu erfassen. Dadurch ist es möglich, dass der jeweils aktuelle Zustand der Komponente 9 direkt und automatisch von der Steuerungseinheit 8 erfasst wird. Insbesondere ist es nicht erforderlich, dass die Komponente 9 selbsttätig den aktuellen Zustand an die Steuerungseinheit 8 übermittelt. Aus der Summe der Einzelzustände der jeweiligen Komponenten 9 kann die Steuerungseinheit 8 einen Betriebszustand der Arbeitsmaschine 2 ermitteln.The control unit 8 is in signal communication with various components 9 of the work machine 2. According to the embodiment shown, five components 9 are provided. It is also possible for more or fewer than five components 9 to be in signal connection with the control unit 8. As components 9, for example Sensors of the working machine 2, such as temperature, pressure, speed or other sensors are used. The components 9 can also be designed as manual switches. By the signal connection of the components 9 with the control unit 8, the respectively current states of the components 9 are transmitted to the control unit 8. It is also possible to enable a signal connection from the control unit 8 to at least one of the components 9 in order to detect the respective current state of the components 9 directly by the control unit 8. This makes it possible that the respective current state of the component 9 is detected directly and automatically by the control unit 8. In particular, it is not necessary for the component 9 to transmit the current state to the control unit 8 automatically. From the sum of the individual states of the respective components 9, the control unit 8 can determine an operating state of the working machine 2.

Im Folgenden wird ein Verfahren zum Bedienen des Fernsteuerungssystems 1 näher erläutert. Zunächst wird das Fernsteuerungssystem 1 mit der Bedieneinheit 3 und der Kommunikationseinheit 4 bereitgestellt. Weiterhin wird die Steuerungseinheit 8 bereitgestellt, die mit der Kommunikationseinheit 4 in Kommunikationsverbindung steht. Anschließend wird mittels der Bedieneinheit 3 eine Bedieneinheit-Ist-Konfiguration erfasst. Die Bedieneinheit-Ist-Konfiguration umfasst insbesondere mehrere Bedien- und Auswahlmenüs zur Anzeige der jeweiligen Konfigurationen und Zustände der Bedienelemente 6 wie beispielsweise Schaltzustände von Tastern oder anderen Schaltelementen. Weiterhin umfasst die Bedieneinheit-Ist-Konfiguration mittels der Anzeige 5 dargestellte Grafiken. Die Bedieneinheit-Ist-Konfiguration wird von der Bedieneinheit 3 über die Kommunikationseinheit 4 an die Steuerungseinheit 8 übermittelt. Anschließend erfasst die Steuerungseinheit 8 eine Arbeitsmaschinen-Ist-Konfiguration. Dies erfolgt insbesondere dadurch, dass der Betriebszustand der Arbeitsmaschine 2 erfasst wird. Der Betriebszustand der Arbeitsmaschine berücksichtigt insbesondere die Kriterien wie Typ der Arbeitsmaschine, also Bagger, Raupenkran, mobiler Kran oder andere Arbeitsmaschine, Aufbauzustand der Arbeitsmaschine, Betriebsart der Arbeitsmaschine wie beispielsweise Fahrmodus, Hebe-/Senkmodus, Drehmodus oder andere Modi, erfasste Maschinendaten und/oder Art der Aktivierung des Fernsteuerungssystems 1. Auf Basis der Arbeitsmaschinen-Ist-Konfiguration und der Bedieneinheit-Ist-Konfiguration wird mindestens eines der Bedien- und Auswahlmenüs in Abhängigkeit der Arbeitsmaschinen-Ist-Konfiguration selektiert. Das bedeutet, dass in Abgängigkeit der Anforderungen an die Arbeitsmaschine darzustellende Grafiken die relevanten Bedien- und Auswahlmenüs bestimmt und aus der Anzahl der verfügbaren Bedien- und Auswahlmenüs selektiert werden. Die als relevant selektierten Bedien- und Auswahlmenüs werden von der Steuerungseinheit 8 über die Kommunikationseinheit 4 an die Bedieneinheit 3 übermittelt und dort mittels der Anzeige 5 dargestellt.In the following, a method for operating the remote control system 1 will be explained in more detail. First, the remote control system 1 is provided with the operation unit 3 and the communication unit 4. Furthermore, the control unit 8 is provided, which communicates with the communication unit 4 in communication. Subsequently, an operating unit-actual configuration is detected by means of the operating unit 3. The operating unit-actual configuration comprises in particular a plurality of operating and selection menus for displaying the respective configurations and states of the operating elements 6, such as switching states of buttons or other switching elements. Furthermore, the control unit-actual configuration by means of the display 5 illustrated graphics. The operating unit-actual configuration is transmitted from the operating unit 3 via the communication unit 4 to the Control unit 8 transmitted. Subsequently, the control unit 8 detects a working machine-actual configuration. This is done in particular by the fact that the operating state of the work machine 2 is detected. The operating state of the work machine particularly takes into account the criteria such as type of work machine, ie excavator, crawler crane, mobile crane or other work machine, construction state of the work machine, working machine operating mode such as travel mode, lifting / lowering mode, rotation mode or other modes, recorded machine data and / or Type of Activation of the Remote Control System 1. Based on the actual working machine configuration and the operating unit actual configuration, at least one of the operating and selection menus is selected depending on the working machine actual configuration. This means that graphs to be displayed in the course of the requirements of the working machine determine the relevant operating and selection menus and are selected from the number of available operating and selection menus. The operating and selection menus selected as relevant are transmitted by the control unit 8 via the communication unit 4 to the operating unit 3 and displayed there by means of the display 5.

Dadurch ist es möglich, ausgehend von einer Anzahl n an Bedien- und Auswahlmenüs, die mittels der Bedieneinheit 3 dargestellt werden könnten, in Abhängigkeit eines Betriebszustands der Arbeitsmaschine 2 auf einige wenige Bedien- und Auswahlmenüs für jeden Betriebszustand zu reduzieren. Insbesondere ist es möglich, dass genau eine, höchstens zwei oder wenige, wie beispielsweise drei bis fünf, Bedien- und Auswahlmenüs pro Betriebszustand dargestellt werden. Für den Fall, dass genau zwei Bedien- und Auswahlmenüs an der Bedieneinheit 3 mittels der Anzeige 5 dargestellt werden sollen, kann dies beispielsweise mittels einer Schaltfläche erfolgen, die ein Umblättern zwischen den beiden genannten, relevanten Bedien- und Anzeigemenüs erfolgen kann. Das Selektieren der relevanten Bedien- und Anzeigemenüs erfolgt insbesondere automatisch mittels der Steuerungseinheit 8, bei der es sich insbesondere um eine elektronische Steuerungseinheit handelt. Dadurch ist eine automatische Steuerung der anzeigegeführten Bedienfunktion des Fernsteuerungssystems 1 möglich. Dadurch ist die Ergonomie für einen Bediener des Fernsteuerungssystems 1 verbessert.This makes it possible, starting from a number n of operating and selection menus, which could be displayed by means of the operating unit 3, depending on an operating state of the working machine 2 to reduce a few operating and selection menus for each operating state. In particular, it is possible for exactly one, at most two or a few, such as three to five, operating and selection menus to be displayed per operating state. In the event that exactly two operating and selection menus are to be displayed on the operating unit 3 by means of the display 5, this can be done, for example, by means of a button which is turned over between the two, relevant operating and display menus can take place. The selection of the relevant operating and display menus is carried out in particular automatically by means of the control unit 8, which is in particular an electronic control unit. As a result, an automatic control of the display-guided operating function of the remote control system 1 is possible. This improves the ergonomics for an operator of the remote control system 1.

Das Fernsteuerungssystem 1, insbesondere die Bedieneinheit 3 und die Kommunikationseinheit 4, ermöglichen einen flexiblen und arbeitsmaschinenunabhängigen Einsatz. Insbesondere ist es nicht erforderlich, dass die Hardware umkonfiguriert oder Software umprogrammiert werden muss. Vorteilhafterweise umfasst die Kommunikationseinheit 4 eine Standardschnittstelle zur Verbindung mit der Steuerungseinheit 8. Diese Standardschnittstelle kann eine Standard-Kabelverbindung sein. Es ist auch möglich, dass die Kommunikationseinheit 4 in die Steuerungseinheit 8 integriert wird. In diesem Fall kann die Kommunikationseinheit 4 auf einem Standard-Steckplatz einer Platine der Steuerungseinheit 8 angeordnet sein. Insbesondere ist es nicht erforderlich, dass die Bedieneinheit 3 und/oder die Kommunikationseinheit 4 maschinentypische Auswertefunktionen übernehmen. Eine typenabhängige Programmierung bzw. Konfiguration erfolgt mittels der ohnehin an der Arbeitsmaschine 2 vorhandenen Steuerungseinheit 8. Das Fernsteuerungssystem 1 dient zur Visualisierung und Bedienung der Arbeitsmaschine. Die Lagerhaltung und insbesondere die Anzahl der Teile und Ersatzteile sind durch die Verwendung eines derartigen Fernsteuerungssystems reduziert.The remote control system 1, in particular the operating unit 3 and the communication unit 4, allow a flexible and machine-independent use. In particular, it is not necessary that the hardware be reconfigured or software reprogrammed. Advantageously, the communication unit 4 comprises a standard interface for connection to the control unit 8. This standard interface may be a standard cable connection. It is also possible that the communication unit 4 is integrated in the control unit 8. In this case, the communication unit 4 may be arranged on a standard slot of a board of the control unit 8. In particular, it is not necessary that the operating unit 3 and / or the communication unit 4 take over machine-typical evaluation functions. A type-dependent programming or configuration by means of the existing anyway on the machine 2 control unit 8. The remote control system 1 is used for visualization and operation of the machine. Warehousing and in particular the number of parts and replacement parts are reduced by the use of such a remote control system.
