Description

Die Erfindung betrifft ein Flurförderzeug mit einem integrierten Datenfunkgerät.The invention relates to a truck with an integrated data radio.

Bei Flurförderzeugen ist bekannt, Flottenmanagementsysteme einzusetzen, über die beispielsweise Zugangsberechtigungen gesteuert werden, fahrerbezogene Einstellungen zugewiesen werden können, außergewöhnliche Ereignisse wie Unfälle erfasst werden und Einsatzdaten, wie zum Beispiel Einsatzzeiten sowie Leistungsdaten, aufgezeichnet werden. Weiterhin ist es auch bekannt, Fehlermeldungen aus einer Fahrzeugsteuerung, wie sie zum Beispiel zu Wartungs- und Reparaturzwecken zum Einsatz kommen, über Datenverbindungen auf Server bzw. an Programme zu übertragen insbesondere an ein Flottenmanagementsystem, so dass diese Daten beispielsweise in den Programmen durch einen Nutzer bzw. Fuhrparkleiter genutzt werden können. Diese Programme können dabei beispielsweise durch den Benutzer als Web-Applikation genutzt werden. Es ist weiterhin denkbar, solche Flottenmanagementsysteme mit Lagerverwaltungssystemen, Fahrzeugleitsystemen oder Dispositionsprogrammen zu verbinden und um beispielsweise ein Energiemanagement der Traktionsbatterie eines Flurförderzeugs zu erweitern. Durch Letzteres können Fahrzeuge betriebsstundenabhängig einzelnen Einsätzen innerhalb einer Fahrzeugflotte zugewiesen werden.In the case of industrial trucks, it is known to use fleet management systems, via which, for example, access authorizations can be controlled, driver-related settings can be assigned, extraordinary events such as accidents can be recorded and operational data, such as operating times and performance data, can be recorded. Furthermore, it is also known to transmit error messages from a vehicle control, such as those used for maintenance and repair purposes, via data connections to servers or programs, in particular to a fleet management system, so that these data, for example in the programs by a user or fleet manager can be used. These programs can be used for example by the user as a web application. It is also conceivable to connect such fleet management systems with warehouse management systems, vehicle control systems or scheduling programs and, for example, to expand energy management of the traction battery of a truck. The latter allows vehicles to be assigned to individual operations within a vehicle fleet depending on the operating hours.

Für diese Anwendungen ist eine Datenübertragung von und zu dem Flurförderzeug erforderlich. Diese Übertragung kann kabelgebunden erfolgen, durch Datenspeicherkarten und per Funk. Bei Übertragung per Funk ist es bekannt, hierfür Bluetooth, WLAN oder Mobilfunk zu nutzen.For these applications, data transmission from and to the truck is required. This transmission can be wired, through data storage cards and by radio. When transmitting by radio, it is known to use this Bluetooth, WLAN or mobile.

Nachteilig an kabelgebundenen Systemen und Datenspeicherkarten ist, dass die Daten aktiv durch eine Person bei dem Flurförderzeug abgeholt werden müssen bzw. zu dem Fahrzeug gebracht werden müssen, indem die Datenspeicherkarte eingesetzt wird oder das Kabel verbunden wird. Dadurch steht zum einen keine kontinuierliche Verbindung zur Verfügung und entstehen Kosten. Zum anderen ist dieses Vorgehen insgesamt aufwändig, relativ unkomfortabel und personalintensiv.A disadvantage of wired systems and data storage cards is that the data must be actively picked up by a person at the truck or brought to the vehicle by the data memory card is inserted or the cable is connected. As a result, there is no continuous connection available and costs arise. On the other hand, this procedure is generally complicated, relatively uncomfortable and labor-intensive.

Es ist daher bekannt, Funklösungen einzusetzen.It is therefore known to use wireless solutions.

Auch wenn dadurch Kosten entstehen, werden, insbesondere vor dem Hintergrund günstiger zur Verfügung stehender Volumentarife, bevorzugt Mobilfunklösungen zur Übertragung der Daten eingesetzt.Even if this results in costs, mobile radio solutions are preferably used for transmitting the data, in particular against the background of more favorable volume tariffs.

Nachteilig an diesem Stand der Technik ist jedoch, dass zusätzlich ein Mobilfunkgerät bzw. Mobilfunkmodem erforderlich wird, über das die Fahrzeugsteuerung mit dem Mobilfunknetz verbunden wird. Dieses Mobilfunkmodem benötigt Bauraum, umfasst typischerweise ein Gehäuse, Stecker, eine eigene Spannungsstabilisierung, einen Prozessor nebst Speicher, ein Mobilfunkmodul, eine SIM Karte sowie eine Antenne. Dabei kann die Antenne zur Optimierung des Empfangs herausgeführt und getrennt angeordnet sein. Als problematisch erweisen sich dabei die Stahlstrukturen von Flurförderzeugen, da das Mobilfunkmodem so angeordnet sein muss, dass ein Empfang möglich ist und dieses sich nicht innerhalb der geschlossenen Stahlstrukturen befindet. Die gleichen Nachteile ergeben sich grundsätzlich bei Bluetooth und WLAN.A disadvantage of this prior art, however, that in addition a mobile device or mobile modem is required, via which the vehicle control system is connected to the mobile network. This mobile modem requires space, typically includes a housing, connector, its own voltage stabilization, a processor and memory, a mobile module, a SIM card and an antenna. In this case, the antenna can be brought out to optimize the reception and arranged separately. The steel structures of industrial trucks prove to be problematic because the mobile radio modem must be arranged so that a reception is possible and this is not within the closed steel structures. The same disadvantages arise in principle with Bluetooth and WLAN.
