Description

Die Erfindung betrifft ein Verfahren zur Verwaltung von Flurförderzeugflotten. Insbesondere betrifft die Erfindung ein Verfahren zur Verwaltung von Flurförderzeugflotten mit mindestens einem Flurförderzeug sowie einem mit einer Flottenverwaltungssoftware verbindbaren mobilen oder stationären Endgerät, wobei das mobile oder stationäre Endgerät und das Flurförderzeug eine Bluetooth-Schnittstelle aufweisen und eine Datenverbindung mit dem mobilen oder stationären Endgerät über Bluetooth erfolgt.The invention relates to a method for managing truck fleets. In particular, the invention relates to a method for managing truck fleets with at least one truck and a connectable with a fleet management software mobile or stationary terminal, the mobile or stationary terminal and the truck have a Bluetooth interface and a data connection to the mobile or stationary terminal via Bluetooth he follows.

Flurförderzeuge werden in Produktionsbetrieben, vor allem in der industriellen Serienfertigung, in großer Anzahl eingesetzt, um den Transport der angelieferten Waren, Rohstoffe und Vorprodukte von der Warenannahme bis zum eigentlichen Produktionsort, etwa einem Fließband, durchzuführen. Bei der Verwaltung dieser Flotten aus Flurförderzeugen, die zumeist aus einer großen Anzahl von beispielsweise durch je einen Fahrer geführten Gabelstaplern bestehen können, stellen sich typische Aufgaben, die im Rahmen eines Flottenmanagements gelöst werden müssen. So müssen die Daten der Flurförderzeuge und von Traktionsbatterien verwaltet werden, mit denen die Benutzung, die den Verschleiß bestimmende Intensität der Benutzung und somit die wirtschaftliche Lebensdauer erfasst und bewertet werden. Dies sind etwa Betriebsstunden, gefahrene Strecken, transportierte Lastgewichte, aufsummierte Hubhöhen von Lastgewichten und die Art der Benutzung kennzeichnende Beschleunigungen. Aufgrund dieser Daten erfolgt dann der Ersatz der Flurförderzeuge im Rahmen des Flottenmanagements. Ebenso müssen für die Flurförderzeuge die Serviceintervalle sowie aufgrund besonderer Ereignisse, wie Ausfällen durch Schäden oder Unfälle, erforderliche Reparaturarbeiten verwaltet werden. Dies erfordert, dass Informationen von den Flurförderzeugen an ein zentrales System, insbesondere einen Computer mit einer Flottenverwaltungssoftware übertragen werden. Ebenso ist aber auch eine Übertragung von Daten in der Gegenrichtung auf die Flurförderzeuge erforderlich. Zum einen, um beispielsweise Daten wie den nächsten fällig werdenden Wartungsdienst lokal auf dem Flurförderzeug in einer elektronischen Steuerungskomponente abzuspeichern, aber auch, um Einstellungen vornehmen zu können. So können durch solche Konfigurationsdaten beispielsweise Zugangsberechtigungen für einzelne Fahrer eingerichtet werden, etwa über eine Codeeingabe durch einen Pin. Ebenso kann alternativ durch diese Daten beispielsweise festgelegt werden, welche von Fahrern als Ausweis mitgeführte Transponderkarten, wie etwa RFID-Transponder, zum Betrieb eines bestimmten Flurförderzeugs berechtigen. Die geschilderten Gesichtpunkte gelten natürlich ebenso für Lagertechnikgeräte, wie Regalkommissionierer, Schubmaststapler, Schlepper und Gabelhubwagen.Industrial trucks are used in production plants, especially in industrial series production, in large numbers, to carry out the transport of the delivered goods, raw materials and precursors of goods receiving to the actual production site, such as a production line. In the management of these fleets of trucks, which can usually consist of a large number of, for example, run by a single driver forklift, are typical tasks that must be solved in the context of fleet management. Thus, the data of the trucks and of traction batteries must be managed, with which the use, the wear determining intensity of use and thus the economic life are recorded and evaluated. These are, for example, operating hours, distances traveled, load weights transported, summed lifting heights of load weights and the type of use characterizing accelerations. Based on this data, the replacement of the material handling equipment takes place as part of the fleet management. Likewise, service vehicles must be managed for their trucks, as well as necessary repairs due to special events such as failure due to damage or accidents. This requires that information from the trucks be transmitted to a central system, in particular a computer with fleet management software. Likewise, however, a transmission of data in the opposite direction to the trucks is required. On the one hand, for example, to store data such as the next due maintenance service locally on the truck in an electronic control component, but also to be able to make settings. Thus, for example, access authorizations for individual drivers can be set up by means of such configuration data, for example via one Code entry through a pin. Likewise, by way of example, these data can be used to specify which transponder cards carried by drivers as identification cards, such as RFID transponders, authorize the operation of a specific industrial truck. Of course, the described points of view also apply to warehouse equipment such as shelf order pickers, reach trucks, tractors and pallet trucks.

Bekannt ist, für die Datenübertragung von und zu den Flurförderzeugen eine Kabelverbindung einzusetzen, die über eine Steckverbindung an das Flurförderzeug angeschlossen wird. Dabei erfolgt die Datenübertragung beispielsweise über das CAN oder das RS232 Protokoll. Nachteilig an diesem Stand der Technik ist, dass die notwendige Steckverbindung abgedichtet gegen Feuchtigkeit und Wasser ausgeführt werden muss, da die Flurförderzeuge zumindest zum Teil auch im Freien eingesetzt werden. Auch ist die Handhabung aufwendig, da das Herstellen der Kabelverbindung Arbeitszeit und somit bei großen Flurförderzeugflotten entsprechendes Personal erfordert. Auch ist die Zugänglichkeit des Anschlusses der Steckverbindung aufgrund des Designs sowie der Integration in Verkleidungsteile des Flurförderzeugs nicht immer gut zu gewährleisten und der Anschluss kann sich an den unterschiedlichsten Stellen befinden. Dies kann dazu führen, dass der Anschluss an dem Flurfördorzeug erst gesucht oder dessen Position in Handbüchern nachgeschaut werden muss. Auch kann es erforderlich sein, dass das Flurförderzeug festgelegte Positionen in einem Firmengelände anfahren muss, da dort der Kabelanschluss ortsfest für den Datenaustausch zur Verfügung steht. Soweit aber der Datenaustausch über mobile Endgeräte, wie etwa über ein Notebook erfolgt, das beispielsweise über ein WLAN die Daten zu dem zentralen Computer weiterleiten kann, ist zusätzliche Hardware notwendig, die beispielsweise ein CAN-Intärface oder einen Umsetzer von RS232 auf USB zur Verfügung stellt. Nachteilig ist, dass durch diese zusätzliche Hardware auch die mögliche Auswahl mobiler Endgeräte beschränkt wird.It is known to use for data transmission from and to the trucks a cable connection, which is connected via a plug connection to the truck. The data transmission takes place, for example, via the CAN or the RS232 protocol. A disadvantage of this prior art is that the necessary connector must be sealed against moisture and water, since the trucks are at least partially used outdoors. The handling is complicated, since the production of the cable connection working time and thus requires corresponding staff for large truck fleets. Also, the accessibility of the connection of the connector is not always easy to ensure due to the design and the integration in trim parts of the truck and the connection can be located in different places. This may mean that the connection to the floorboard tool first has to be searched for or its position in manuals has to be looked up. It may also be necessary for the industrial truck to approach fixed positions in a company premises, since the cable connection there is stationary for data exchange. However, as far as the data exchange via mobile devices, such as via a notebook, which can forward the data to the central computer, for example via a WLAN, additional hardware is necessary, which provides, for example, a CAN interface or a converter from RS232 to USB , The disadvantage is that this additional hardware also limits the possible choice of mobile devices.

Bekannt ist für Diagnosezwecke sowie Servicezwecke die drahtlose Übertragung von Daten von und zu einem Flurförderzeug. Dabei können die übertragenen Daten auch Informationen über die Beanspruchung des Flurförderzeugs umfassen. Bei diesen drahtlosen Verbindungen entsteht das Problem, dass die Flurförderzeuge, mit denen gerade eine Verbindung besteht, nicht eindeutig identifiziert werden können. Wenn auf einem Firmengefände per drahtloser Funkverbindung mit einem Flurförderzeug eine Datenverbindung aufgebaut wird, so ist im Gegensatz zu einer Verbindung über ein Kabel nicht automatisch eindeutig, mit welchem Flurförderzeug die Verbindung besteht. Auch besteht kein Schutz gegen unberechtigten Zugriff und Manipulationen Dritter. Die Flurförderzeuge bei der Aufnahme in eine Flurförderzeugflotte mit eindeutigen Bezeichnungen zu versehen und diese auf den Fahrzeugen zu hinterlegen ist jedoch aufwendig und kann zu Fehlern führen.For diagnostic and service purposes, wireless transmission of data to and from an industrial truck is known. The transmitted data may also include information about the load on the truck. With these wireless connections, the problem arises that the trucks that are currently connected can not be clearly identified. If a data connection is established on a company premises via wireless radio link with a truck, then in contrast to a connection via a Cable not automatically clear with which truck the connection exists. There is also no protection against unauthorized access and manipulation of third parties. However, to provide the trucks when recording in a truck fleet with clear names and to deposit them on the vehicles is expensive and can lead to errors.

Bekannt sind bei Computern Datenverbindungen nach dem Bluetooth-Standard. Dieser bietet die Möglichkeit der Verschlüsselung und der Identifizierung der Bluetooth-Geräte durch Bluetooth-Adresse und Gerätenamen.Computers are known data connections to the Bluetooth standard. This offers the possibility of encryption and identification of Bluetooth devices by Bluetooth address and device name.

Aus der DE 102008033386 A1 , ist ein Verfahren zur Verwaltung von Flurförderzeugflotten nach dem Oberbegriff des Patentanspruchs 1 bekannt.From the DE 102008033386 A1 , A method for managing truck fleets according to the preamble of claim 1 is known.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Verwaltung von Flurförderzeugflotten zur Verfügung zu stellen, mit dem auf einfache und zuverlässige Art und Weise ein Flurförderzeug mit einem mobilen oder stationären Endgerät verbunden werden kann, um Daten mit einer Flottenverwaltungssoftware austauschen zu können.The present invention is therefore based on the object to provide a method for managing truck fleets available, with a simple and reliable way an industrial truck can be connected to a mobile or stationary terminal to exchange data with a fleet management software can.

Diese Aufgabe wird durch ein Verfahren zur Verwaltung von Flurförderzeugflotten mit den Merkmalen der Anspruchs 1 sowie durch ein System mit den Merkmalen des Anspruchs 9 gelöst. Vorteilhafte Ausgestaltungen der Erfindung geben die Unteransprüche an.This object is achieved by a method for managing truck fleets with the features of claim 1 and by a system having the features of claim 9. Advantageous embodiments of the invention give the dependent claims.

Die Aufgabe wird durch ein Verfahren zur Verwaltung von Flurförderzeugflotten mit mindestens einem Flurförderzeug sowie einem mit einer Flottenverwaltungssoftware verbindbaren mobilen oder stationären Endgerät gelöst, wobei das mobile oder stationäre Endgerät und das Flurförderzeug eine Bluetooth-Schnittstelle aufweisen und eine Datenverbindung mit dem mobilen oder stationären Endgerät über Bluetooth erfolgt. Dabei ist in einem Gerätenamen der Bluetooth-Schnittstelle des Flurförderzeugs eine Fahrzeugserlennummer des Flurförderzeugs enthalten.The object is achieved by a method for managing truck fleets with at least one truck and a connectable with a fleet management software mobile or stationary terminal, the mobile or stationary terminal and the truck have a Bluetooth interface and a data connection to the mobile or stationary terminal over Bluetooth is done. In this case, a vehicle serial number of the industrial truck is contained in a device name of the Bluetooth interface of the industrial truck.

Sehr viele als mobile oder stationäre Engeräte geeignete Geräte aus dem Bereich des Mobilfunk und der Computer weisen bereits eine Bluetooth-Schnittstelle auf. Das Flurförderzeug kann mit sehr geringem Aufwand mit einer Bluetooth-Schnittstelle versehen werden, die auch leicht aufgrund der Baugröße und, da keine äußeren Anschlüsse erforderlich sind, integriert werden kann, beispielsweise in einen elektronischen Steuerungsrechner oder in eine elektronischen Steuerungskomponente eines Flottenmanagementsystems des Flurförderzeugs eingebaut werden kann. Die Endgeräte stellen auch regelmäßig bereits eine Verbindung zu einem Netzwerk, insbesondere dem Internet, zur Verfügung, über die Daten mit einer Flottenverwaltungssoftware auf einem zentralen Rechner ausgetauscht werden können. Dabei können die Daten mit der Flottenverwaltungssoftware sofort ausgetauscht werden und/oder auch auf dem mobilen Endgerät zwischengespeichert werden, wenn z.B. zeitweilig die Verbindung zu dem Netzwerk nicht möglich ist. Für ein Verfahren zur Verwaltung von Flurförderzeugflotten ist die Anbindung der mobilen oder stationären Endgeräte über eine Bluetooth Schnittstelle von besonders großem Vorteil, da zum einen eine Vielzahl von Flurförderzeugen in einer Flurförderzeugflotte mit der Flottenverwaltungssoftware verbunden werden muss und zum anderen diese Verbindung auch noch sehr häufig und regelmäßig in dem Betrieb des Flurförderzeugs erfolgen muss. Lösungen die für eine Wartungsverbindung zu dem Flurförderzeug bekannt sind und eine besondere Hardware erfordern, sind daher gerade nicht geeignet für ein Verfahren zur Verwaltung von Flurförderzeugflotten. Es ist auch denkbar, dass neben mobilen Endgeräten stationär angeordnete Endgeräte, beispielsweise Computer oder Geräte mit Bluetooth-Schnittstelle, für die Verbindung eingesetzt werden, wenn diese sich in einem Bereich befinden, in dem sich die Flurförderzeug für die Durchführung eines Datenaustausches lange genug aufhalten. Dafür muss der Empfangsbereich entsprechend groß ausgelegt sein. Die Fahrzeugseriennummer ist für ein Flurförderzeug eindeutig und wird bei der Herstellung festgelegt. Diese Fahrzeugseriennummer kann Ober eine Steuerung des Flurförderzeugs abfragbar zur Verfügung gestellt werden. Wenn die Fahrzeugseriennumer in den sprechenden Namen des Bluetoothgeräts als Teil aufgenommen wird, oder diesem entspricht, kann das Flurförderzeug eindeutig identifiziert werden über die Biuetooth-Gerätekennung, ohne dass zuvor bei der Eingliederung des Flurförderzeugs in die Flurförderzeugflotte eine Hintertegung einer Bezeichnung auf dem Flurförderzeug erforderlich ist. Über eine Signaleinrichtung, beispielsweise eine LED, kann bei bestehender Verbindung auf dem Flurförderzeug eine Rückmeldung erfolgen.Many mobile or stationary devices suitable devices from the field of mobile and computer already have a Bluetooth interface. The truck can be provided with very little effort with a Bluetooth interface, which is also easy due to the size and, as no external Connections are required, can be integrated, for example, in an electronic control computer or in an electronic control component of a fleet management system of the truck can be installed. The terminals also regularly provide a connection to a network, in particular the Internet, available via which data can be exchanged with a fleet management software on a central computer. The data can be exchanged with the fleet management software immediately and / or be cached on the mobile device if, for example, the connection to the network is temporarily not possible. For a method for managing truck fleets, the connection of the mobile or stationary terminals via a Bluetooth interface is particularly advantageous, since on the one hand a large number of industrial trucks in a truck fleet with the fleet management software must be connected and on the other hand, this connection is still very common and must be carried out regularly in the operation of the truck. Solutions that are known for a maintenance connection to the truck and require special hardware are therefore just not suitable for a method for managing truck fleets. It is also conceivable that in addition to mobile terminals stationarily arranged terminals, such as computers or devices with Bluetooth interface, are used for the connection, if they are located in an area in which the truck to conduct a data exchange long enough. For this, the reception area must be designed to be correspondingly large. The vehicle serial number is unique for an industrial truck and is determined during manufacture. This vehicle serial number can be made available via a control of the truck in an interrogatable manner. When the vehicle serial number is included in or matches the talking name of the Bluetooth device, the truck can be uniquely identified via the biuetooth device identifier without requiring a designation on the truck when integrating the truck into the truck fleet , A signaling device, for example an LED, can be used to confirm the presence of a connection on the truck.

In einer vorteilhaften Ausgestaltung wird bei dem erfindungsgemäßen Verfahren auf dem mobilen oder stationären Endgerät eine Datenbank mit Zuordnungen von Fahrzeugseriennummern zu Bluetooth-Adressen abgelegt und bei einem zweiten oder folgenden Verbindungsaufbau zu dem Flurförderzeug wird die Bluetooth-Schnittstelle mithilfe der gespeicherten Bluetooth-Adresse gesucht.In an advantageous embodiment, a database with assignments of vehicle serial numbers to Bluetooth addresses is stored in the inventive method on the mobile or stationary terminal and in a second or subsequent connection to the truck, the Bluetooth interface using the stored Bluetooth address is searched.

Dadurch kann der Verbindungsaufbau beschleunigt werden und insbesondere sichergestellt werden, dass es nicht zunächst bei der Suche nach einem Flurförderzeug zu fälschlichen Verbindungen zu anderen Flurförderzeugen kommt. Vor allem wenn die mobilen oder stationären Endgeräte von den Fahrern, etwa als Smartphone, mitgeführt werden, ergibt sich dadurch rasch eine jeweils richtige Verbindung zu dem gewünschten Flurförderzeug.As a result, the connection can be accelerated and in particular ensured that it does not come first in the search for a truck to fake connections to other trucks. Especially when the mobile or stationary terminals are carried by the driver, such as a smartphone, this results in each case a quick connection to the desired truck.

Die Datenkommunikation zwischen Flurförderzeug und Endgerät kann über ein OBEX-Protokoll und/oder ein FTP-Protokoll erfolgen.The data communication between truck and terminal can be done via an OBEX protocol and / or an FTP protocol.

Vorteilhaft erfolgt eine Überprüfung der Zugriffsberechtigung in der OBEX-Protokollschicht.Advantageously, the access authorization in the OBEX protocol layer is checked.

Diese standardisierten Verfahren stellen einen Datenaustausch mit der Möglichkeit zusätzlicher Authentifizierung und Verschlüsselung zur Verfügung.These standardized methods provide a data exchange with the possibility of additional authentication and encryption.

Die Bluetooth-Verbindung kann über einen PIN-Code verschlüsselt werden.The Bluetooth connection can be encrypted via a PIN code.

Eine Bluetooth-Verbindung ist gerade dafür ausgelegt, den unberechtigten Zugriff Dritter zu verhindern und bietet daher sehr kostengünstig die Möglichkeit einen unberechtigten Zugriff Dritter zu verhindern.A Bluetooth connection is just designed to prevent the unauthorized access of third parties and therefore offers very low cost the ability to prevent unauthorized access by third parties.

Mit besonderem Vorteil ist gemäß einer Ausführungsform der Erfindung das mobile Endgerät ein Notebook oder PDA.With particular advantage, according to one embodiment of the invention, the mobile terminal is a notebook or PDA.

In einer günstigen Ausgestaltung des Verfahrens ist das mobile Endgerät ein Smartphone.In a favorable embodiment of the method, the mobile terminal is a smartphone.

Durch die zunehmende Verbreitung und die vorhandene Rechenkapazität der Smartphones stellen diese eine vorteilhafte Option für ein mobiles Endgerät dar. Vor allem werden diese Geräte in großer Anzahl von den das Flurförderzeug bedienenden Personen mitgeführt und in unmittelbare Nähe der Flurförderzeuge gebracht.Due to the increasing distribution and the available computing capacity of smartphones, they represent an advantageous option for a mobile terminal. Above all, these devices are carried in large numbers by the persons using the industrial truck and brought into the immediate vicinity of the industrial trucks.

In günstiger Ausführungsform des Verfahrens stellt eine Application des Smartphone die Verbindung mit dem Flurförderzeug über Bluetooth und mit einer Flottenverwaltungssoftware über das Internet oder ein WLAN her.In a favorable embodiment of the method, an application of the smartphone establishes the connection with the industrial truck via Bluetooth and with fleet management software via the Internet or a WLAN.

Bei der vorhandenen Rechenleistung kann ohne Beeinträchtigung der sonstigen Funktionen ein Smartphone die Verbindung herstellen, Auch ist regelmäßig bereits eine Bluetooth-Schnittstelle sowie ein Internetzugang über Mobilfunk vorhanden. Der Internetzugang kann auch über ein WLAN erfolgen, wobei es denkbar wäre, das Smartphone über WLAN direkt mit einem Firmennetzwerk und einem zentralen Rechner sowie der Flottenverwaltungssoftware zu verbinden.With the existing computing power, a smartphone can establish the connection without impairing the other functions. Also, a Bluetooth interface and Internet access via mobile radio are already available on a regular basis. Internet access can also be done via a WLAN, whereby it would be conceivable to connect the smartphone via WLAN directly with a company network and a central computer as well as the fleet management software.

Alternativ ist natürlich auch eine Anbindung über ein LAN, etwa eines Notebooks, denkbar, oder, wenn als mobiles Endgerät ein PDA eingesetzt wird, kann dieses über USB mit einem Rechner synchronisiert werden, der mit dem Internet verbunden ist.Alternatively, of course, a connection via a LAN, such as a notebook, conceivable, or if a PDA is used as a mobile device, this can be synchronized via USB with a computer that is connected to the Internet.

Die Aufgabe wird auch durch ein System aus einer Mehrzahl von Flurförderzeugen sowie mindestens einem mobilen oder stationären Endgerät gelöst, das ein Verfahren durchführt, wie es zuvor beschrieben wurde.The object is also achieved by a system comprising a plurality of industrial trucks and at least one mobile or stationary terminal, which performs a method as described above.

Ein solches System weist die bereits genannten Vorteile auf. Die Vorteile kommen jedoch besonders zum Tragen bei Flurförderzeugflotten mit einer sehr großen Anzahl an Fahrzeugen, da dann das gezielte Ansprechen des gesuchten Flurförderzeugs und schnelle Auffinden besonders vorteilhaft ist. Wenn etwa alle oder zumindest eine Mehrzahl an Fahrern, die ein bestimmtes Flurförderzeug benutzen, in einem mitgeführten Smartphone eine Verbindung über Bluetooth zu dem Flurförderzeug ermöglichen, so kann das Flurförderzeug zuverlässig und innerhalb eines kurzen Zeitraums erreicht werden.Such a system has the advantages already mentioned. However, the advantages come especially to bear on industrial trucks fleets with a very large number of vehicles, since then the targeted response of the truck and fast finding is particularly advantageous. If, for example, all or at least a large number of drivers who use a specific industrial truck enable a connection via Bluetooth to the industrial truck in a mobile phone, the industrial truck can be reached reliably and within a short period of time.

Die Erfindung betrifft auch ein Softwareprodukt, das in den Speicher eines Smartphones geladen und auf dem Smartphone ablaufend das zuvor beschriebene Verfahren durchführt, bei dem eine Application des Smartphone die Verbindung mit dem Flurförderzeug über Bluetooth und mit einer Flottenverwaltungssoftware über das Internet oder ein WLAN herstellt.The invention also relates to a software product that is loaded into the memory of a smartphone and running on the smartphone the previously described Performs a method in which an application of the smartphone makes the connection to the truck via Bluetooth and with a fleet management software via the Internet or a WLAN.

Vorteilhaft kann eine Software zur Durchführung des Verfahrens in die bestehenden Systeme aus "Apps" als Anwendungssoftware bei Smartphones integriert werden.Advantageously, software for implementing the method can be integrated into the existing systems from "apps" as application software for smartphones.

Weitere Vorteile und Einzelheiten der Erfindung werden anhand des in der Figur dargestellten Ausführungsbeispiels näher erläutert. Hierbei zeigt die Figur eine schematische Darstellung der Verbindung eines Flurförderzeugs mit einem mobilen Endgerät sowie einer Flottenverwaltungssoftware.Further advantages and details of the invention will be explained in more detail with reference to the embodiment shown in the figure. The figure shows a schematic representation of the connection of a truck with a mobile terminal and a fleet management software.

Ein beispielsweise als Gegengewichtsgabelstapler 1 ausgebildeten Flurförderzeugs 2 weist einen Bluetooth-Sender Empfänger auf, der eine Bluetooth-Schnittstelle 4 bildet und mit einem nicht dargestellten elektronischen Steuerungsrechner, beispielsweise einer elektronischen Steuerungskomponente eines Flottenmanagementsystems, des Flurförderzeugs 2 verbunden ist. Der dargestellte Gegengewichtsgabelstapler 1 weist ein Gegengewicht 5 und ein Hubgerüst 6 mit einer Lastgabel 7 auf.A for example designed as a counterbalance forklift truck 1 2 has a Bluetooth transmitter receiver, which forms a Bluetooth interface 4 and is connected to an electronic control computer, not shown, for example, an electronic control component of a fleet management system of the truck 2. The illustrated counterbalance forklift 1 has a counterweight 5 and a mast 6 with a fork 7 on.

Von dem Flurförderzeug 2 werden auf nicht mehr dargestellte Weise im Betrieb Betriebsdaten, beispielsweise Betriebsstunden, gefahrene Strecken, transportierte Lastgewichte, Hubhöhen von Masten, Art der Benutzung kennzeichnende Beschleunigungen, Schäden oder Unfallereignisse, Reparaturarbeiten, erfasst und in dem elektronischen Steuerungsrechner abgespeichert.From the truck 2 operating data, such as operating hours, driven routes, transported load weights, lifting heights of masts, type of use characterizing accelerations, damage or accident events, repair work, recorded and stored in the electronic control computer in a manner not shown in operation.

Ein Endgerät 8, beispielsweise ein mobiles Endgerät 8 in Form eines Notebooks 9, ist über eine integrierte Bluetooth-Schnittstelle des Notebooks 9 mit der Bluetooth-Schnittstelle 4 des Flurförderzeugs 2 verbunden, wie durch den Doppelpfeil angedeutet. Dabei wurde von dem Steuerungsrechner bzw. dem Bluetooth-Sender Empfänger des Flurförderzeugs 2 eine Fahrzeugseriennummer als Bluetooth-Gerätenamen übertragen. In dem Notebook 9 wird eine Datenbank abgelegt, die Fahrzeugseriennummern zu Bluetooth-Adressen zuordnet und ein schnelles Finden eines bestimmten Flurförderzeugs ermöglicht.A terminal 8, for example a mobile terminal 8 in the form of a notebook 9, is connected via an integrated Bluetooth interface of the notebook 9 with the Bluetooth interface 4 of the truck 2, as indicated by the double arrow. In this case, a vehicle serial number was transmitted as Bluetooth device name by the control computer or the Bluetooth transmitter receiver of the truck 2. In the notebook 9, a database is stored, which assigns vehicle serial numbers to Bluetooth addresses and allows a quick Find a specific truck.

Das Notebook 9 kann über eine WLAN-Verbindung, wie ebenfalls durch einen Doppelpfeil angedeutet, und eine Antenne 10 mit einem zentralen Rechner 11 verbunden werden, auf dem die Flottenverwaltungssoftware läuft. Wenn ein Datenaustausch mit dem Flurförderzeug 2 stattfindet, können die Daten zunächst zwischengespeichert werden und nachfolgend, oder auch sofort an den zentralen Rechner 11 übertragen werden. Die Bluetooth-Verbindung mit dem Flurförderzeug 2 erfolgt verschlüsselt und über OBEX-Protokoll.The notebook 9 can be connected via a WLAN connection, as also indicated by a double arrow, and an antenna 10 to a central computer 11, on which runs the fleet management software. If a data exchange takes place with the truck 2, the data can first be cached and subsequently, or even immediately transferred to the central computer 11. The Bluetooth connection with the truck 2 is encrypted and via OBEX protocol.

Alternativ kann anstatt dem Notebook 9 auch ein Smartphone 12 als mobiles Endgerät 8 eingesetzt werden, das dieselbe Funktionalität wie das Notebook 9 als mobiles Endgerät zur Verfügung stellt. Vorteilhaft kann das Verfahren auf dem Smartphone 12 allein durch eine Software, etwa als "App", umgesetzt werden und stehen durch die von Fahrern mitgeführten Smartphones 12 diese in großer Anzahl als mobile Endgeräte zur Verfügung.Alternatively, instead of the notebook 9, a smartphone 12 can be used as a mobile terminal 8, which provides the same functionality as the notebook 9 as a mobile terminal. Advantageously, the method can be implemented on the smartphone 12 solely by software, such as an "app", and are available in large numbers as mobile terminals by the smartphones 12 carried by drivers.

Über die Bluetooth-Verbindung zwischen dem Flurförderzeug 2 und dem mobilen Endgerät 8 können für die Flottenverwaltung auf einfache Weise Konfigurationsdaten, beispielsweise Zugangberechtigungen für Fahrer, mit dem mobilen Endgerät 8 in das Flurförderzeug 2 eingespeist werden oder Betriebsdaten, die von dem Flurförderzeug 2 im Betrieb erfasst und abgespeichert wurden, von dem Flurförderzeug 2 auf das mobile Endgerät 8 ausgelesen werden.Via the Bluetooth connection between the industrial truck 2 and the mobile terminal 8, configuration data, for example access authorizations for drivers, can be fed into the industrial truck 8 with the mobile terminal 8 or operating data acquired by the industrial truck 2 during operation for the fleet management and were stored, are read from the truck 2 to the mobile terminal 8.
