Description

Die Erfindung betrifft einen Straßenfertiger der im Oberbegriff des Patentanspruchs 1 angegebenen Art sowie eine Datenspeichervorrichtung gemäß Patentanspruch 12.The invention relates to a road paver specified in the preamble of claim 1 and a type of data storage device according to claim 12.

Die Elektronikausstattung des aus der Praxis und aus dem auf der BAUMA 2004 verteilten Prospekt "SUPER 1800-1" Raupenfertiger, der Firma Joseph Vögele AG, bekannten Straßenfertiger umfasst eine bordeigene Zentralrecheneinheit im Bedienpult, sowie mehrere zentrale oder dezentrale speicherprogrammierbare Steuerungen und Controllereinheiten, mehrere zentrale oder dezentrale Eingangs-/Ausgangs-Module, Außensteuerstände, eine Motorelektronik, eine Generatorelektronik und diverse Sensorik- und Aktorik-Subsysteme, die direkt oder indirekt in einen Feldbus eingegliedert sind. Zum Betreiben des Straßenfertigers werden verschiedenartige Maschinenparameter mittels eingegebener Daten eingestellt, die zumindest überwiegend in der Zentralrecheneinheit als zentralem Datenspeicher gespeichert werden. Bei Ausfall der Zentralrecheneinheit gehen die eingestellten Maschinenparameter verloren, und es muss nach Reparatur oder Austausch der Zentralrecheneinheit eine Neuparametrierung durchgeführt werden. Da einzelne Subsysteme, oder die Zentralrecheneinheit und dgl. ausfallen können und dann in einem Servicefall ausgetauscht werden, ist es bekannt, die Maschinenparameter-Daten in mehreren Subsystemen innerhalb des Steuerungssystems redundant abzuspeichem, so dass nach einem Austausch einer Komponente die Maschinenparameter-Daten dennoch im System erhalten bleiben. Das redundante Abspeichem erfordert eine teure und leistungsfähige Ausbildung der für diese Aufgabe herangezogenen Subsysteme oder Komponenten und benötigt unzweckmäßig viele verteilte, hohe Speicherkapazitäten. Dennoch können Daten von den aktiven Komponenten verloren gehen.The electronic equipment of the distributed from BAUMA 2004 prospectus "SUPER 1800-1" tracked paver, the company Joseph Vögele AG, known road paver includes an on-board central processing unit in the control panel, as well as several central or decentralized programmable logic controllers and controller units, several central or decentralized input / output modules, external control stations, engine electronics, generator electronics and various sensor and actuator subsystems that are incorporated directly or indirectly into a fieldbus. To operate the paver various machine parameters are set by means of input data, which are stored at least predominantly in the central processing unit as a central data memory. If the central processing unit fails, the set machine parameters are lost and a new parameterization must be carried out after repair or replacement of the central processing unit. Since individual subsystems, or the central processing unit and the like can fail and are then replaced in a service case, it is known to redundantly store the machine parameter data in several subsystems within the control system, so that after a replacement of a component, the machine parameter data in System to be preserved. The redundant Abspeichem requires an expensive and powerful training used for this task subsystems or components and inexplicably requires many distributed, high storage capacity. Nevertheless, data can be lost from the active components.

Beispiele solcher Maschinenparameter sind: Drehzahlvorgaben, Pressleisten- und/oder Tamper-Drehzahlen und Versorgungs-Mengen, Einstellungen der Zuführ- und Verteilleistung des Einbauguts, Temperaturvorgaben für die Beheizung von Arbeitskomponenten, Anstellwinkel der Einbaubohle, Arbeitsbreite der Einbaubohle, Einstellungen der Einbauaggregate, Einbaumaterialvorlagemenge, Einbaudicke, Einstellvorgaben für Hydropumpen und/oder Hydromotoren, Einstellvorgaben der Nivellierautomatik, falls vorhanden, und dgl..Examples of such machine parameters are: speed specifications, pressure bar and / or tamper speeds and supply quantities, feed and distribution capacity settings of the component to be installed, temperature specifications for the heating of working components, screed angle of attack, working width of the screed, settings of the installation units, amount of installed material, Installation thickness, setting specifications for hydraulic pumps and / or hydraulic motors, setting specifications of the automatic leveling system, if available, and the like.

Der Erfindung liegt die Aufgabe zugrunde, einen Straßenfertiger der eingangs genannten Art zu schaffen, bei dem in einem für die bereits vorhandene Parametrierung kritischen Servicefall eine Neuparametrierung vermieden werden kann.The invention has for its object to provide a paver of the type mentioned, in which in a for the already existing parameterization service case a reparameterization can be avoided.

Die gestellte Aufgabe wird mit den Merkmalen der Patentansprüche 1 und 12 gelöst.The stated object is achieved with the features of claims 1 and 12.

Die in der Zentralrecheneinheit eingestellten Maschinenparameter werden als Daten in der Datenspeichervorrichtung abgespeichert und stehen immer zur Verfügung. Bei einem Ausfall beispielsweise der Zentralrecheneinheit sind sämtliche vorher eingestellte Maschinenparameter gesichert und nach Behebung der Störung oder Austausch der Zentralrecheneinheit, bei Austausch des Bedienpults oder anderer Steuerkomponenten sofort wieder nutzbar. Die Datenspeichervorrichtung kann im Servicefall am Straßenfertiger verbleiben, so dass die Zentralrecheneinheit die Daten ohne zeitaufwändige Neuparametrierung wieder zu beschaffen vermag. Ist auch die Komponente des Steuersystems auszutauschen, an der die Datenspeichervorrichtung austauschbar angebracht ist, dann wird die Datenspeichervorrichtung abgenommen und nachfolgend wieder angebracht. Die Datenspeichervorrichtung bildet sozusagen eine dezentrale passive Aufbewahrungsstelle für die Maschinenparameter-Daten, wird regelmäßig aktualisiert, und entlastet die Zentralrecheneinheit und damit verbundene Subsysteme. Die Datenspeichervorrichtung und/oder der Datenaustauschanschluss kann in üblicher Weise abgesichert sein, um zu verhindern, dass bei einem Ausfall Daten verloren gehen oder ein zum Ausfall führender Fehler in die Datenspeichervorrichtung übertragen wird. Die Datenspeichervorrichtung ist passiv und deshalb besser zur Sicherung der Daten geeignet als im Straßenfertiger aktive Komponenten oder Subsysteme, die aufgrund ihrer Aktivität im Betrieb Schäden erleiden können.The machine parameters set in the central processing unit are stored as data in the data storage device and are always available. In the event of a failure of, for example, the central processing unit, all previously set machine parameters are saved and, once the malfunction or replacement of the central processing unit has been rectified, immediately reusable when the control panel or other control components are replaced. The data storage device can remain on the paver in case of service, so that the central processing unit is able to retrieve the data without time-consuming re-parameterization. Also, if the component of the control system to which the data storage device is interchangeably replaced is replaced, the data storage device is removed and subsequently replaced. The data storage device, so to speak, forms a decentralized passive storage location for the machine parameter data, is regularly updated, and relieves the central processing unit and associated subsystems. The data storage device and / or the data exchange port may be conventionally secured to prevent loss of data in the event of a failure or failure leading failure to be transferred to the data storage device. The data storage device is passive and therefore more suitable for securing the data than active components or subsystems in the paver that may suffer damage due to their activity in operation.

Zweckmäßig wird der Datenaustauschanschluss in der Nähe der Zentralrecheneinheit stationär platziert, um kurze Übertragungswege sicherzustellen.Conveniently, the data exchange port is placed in the vicinity of the central processing unit to ensure short transmission paths.

Bei einer zweckmäßigen Ausführungsform ist der Datenaustauschanschluss im oder am Bedienpult, vorzugsweise in einer Seitenwand oder in der Rückwand, angeordnet, wobei die Zentralrecheneinheit wie üblich im Bedienpult untergebracht sein kann. Wird in einem Servicefall das Bedienpult ausgewechselt, braucht die Datenspeichervorrichtung nur abgenommen und am neuen Bedienpult wieder angebracht zu werden, damit die vorhandene Parametrierung wieder verfügbar ist.In an expedient embodiment, the data exchange connection in or on the control panel, preferably in a side wall or in the rear wall, arranged, wherein the central processing unit can be accommodated as usual in the control panel. If the control panel is replaced in a service case, the data storage device only needs to be removed and attached to the new control panel so that the existing parameterization is available again.

Bei einer alternativen Ausführungsform kann der Datenaustauschanschluss auch an oder in einer üblicherweise am Führerstand angeordneten Elektronikbox angeordnet werden.In an alternative embodiment, the data exchange connection can also be arranged on or in an electronics box usually arranged on the driver's cab.

Besonders zweckmäßig wird der Datenaustauschanschluss an einem demontierbaren Gehäusedeckel vorgesehen, der im Servicefall abgenommen und an der Tauscheinheit wieder angebracht werden kann.Particularly expedient the data exchange connection is provided on a removable housing cover, which can be removed in case of service and attached to the exchange unit again.

Im Hinblick auf bequeme Handhabung kann der Datenaustauschanschluss ein Steckanschluss sein, wobei die Datenspeichervorrichtung einen lösbar in den Steckanschluss passenden Stecker aufweist. Der Austausch der Datenspeichervorrichtung ist somit bequem mit wenigen Handgriffen möglich.For ease of use, the data exchange port may be a plug-in port, with the data storage device having a plug releasably mating with the plug-in port. The replacement of the data storage device is thus easily possible with a few simple steps.

Da die Umgebungsbedingungen in einem Straßenfertiger naturgemäß relativ grob sein können, ist es zweckmäßig, wenn die Datenspeichervorrichtung ein stabiles und kompaktes, vorzugsweise annähernd zylindrisches, Außengehäuse aufweist, in welchem zumindest eine Mikrospeichereinheit, vorzugsweise mit einer internen Speicherlogik, untergebracht ist. Die Datenspeichervorrichtung ist ein kompaktes und kostengünstiges Zubehörteil des Straßenfertigers oder für solche Straßenfertiger..Since the environmental conditions in a paver can naturally be relatively coarse, it is expedient if the data storage device has a stable and compact, preferably approximately cylindrical, outer housing in which at least one micro-storage unit, preferably with an internal storage logic, is accommodated. The data storage device is a compact and inexpensive accessory of the road paver or for such road pavers.

Um eine zufällige ungewollte oder unbefugte Abnahme der Datenspeichervorrichtung zu verhindern, ist es zweckmäßig, am Datenaustauschanschluss und/oder an der Datenspeichervorrichtung wenigstens ein Sicherungselement für die Steckverbindung vorzusehen. Dieses Sicherungselement umfasst beispielsweise einen Schraub-, Bajonett-, Rast- oder Spannbügel-Verschluss, der einerseits sicher, andererseits jedoch leicht zu bedienen ist. Gegebenenfalls ist dieser Verschluss sogar absperrbar, um eine unbefugte Abnahme der Datenspeichervorrichtung während Arbeitspausen zu verhindern. Der Verschluss schützt die galvanische Verbindung auch gegen Schmutz, Wtterungseinflüsse oder agressive Medien.In order to prevent accidental unintentional or unauthorized removal of the data storage device, it is expedient to provide at least one securing element for the plug-in connection at the data exchange connection and / or at the data storage device. This securing element includes, for example, a screw, bayonet, locking or clamping yoke closure, on the one hand safe, but on the other hand, easy to use. Optionally, this lock is even lockable to to prevent unauthorized removal of the data storage device during breaks in work. The closure also protects the galvanic connection against dirt, weathering or aggressive media.

Bei einer bevorzugten Ausführungsform ist am Außengehäuse der Datenspeichervorrichtung eine den Stecker umgebende, ein inneres Gewinde oder ein inneres Bajonettelement aufweisende Überwurfmutter drehbar gehaltert, und wird der Steckanschluss des Datenaustauschanschlusses von einem Schutzkragen umgeben, der ein Gegengewinde oder ein Gegenbajonettelement aufweist. Gegebenenfalls kann die Datenspeichervorrichtung sogar über eine Kette oder dgl. unverlierbar und nicht entwendbar im Führerstand des Straßenfertigers gesichert sein.In a preferred embodiment, a cap nut surrounding the plug, an internal thread or an inner bayonet element is rotatably supported on the outer housing of the data storage device, and the plug connection of the data exchange connection is surrounded by a protective collar having a counter thread or a counter bayonet element. Optionally, the data storage device can even be secured via a chain or the like. Captive and not stolen in the cab of the paver.

In jedem Falle sollte die Datenspeichervorrichtung baumaschinentauglich ausgebildet sein, d.h. erheblichen mechanischen Belastungen widerstehen und, beispielsweise, gegen Datenverlust oder Störung bei der Datenübertragung abgeschirmt sein.In any case, the data storage device should be designed to be suitable for construction machinery, i. withstand considerable mechanical stresses and, for example, be shielded against data loss or interference during data transmission.

Diese Komponenten des Steuersystems werden zum Betreiben des Straßenfertigers für Steuer-, Regel- und Überwachungsfunktionen benutzt, wobei zumindest in einen Speicherbereich der zentralen Recheneinheit Z Maschinenparameter in Form von Daten eingegeben und gespeichert werden, auf die die elektronische Steuerungsvorrichtung im Betrieb des Straßenfertigers laufend zurückgreift und die, falls erforderlich, im Betrieb zwecks Umstellung an der zentralen Rechercheneinheit Z, bzw. an einer Anzeige- und Eingabesektion 11 des Bedienpults B geändert werden können. Die Maschinenparameter sind hierbei nicht nur einfache Grunddaten, die für verschiedene Straßenfertiger brauchbar sind, sondern auch Daten, die z.B. spezifisch für nur diesen Straßenfertiger und/oder dessen Einbauaufgabe brauchbar sind.A paver F shown schematically in FIG. 1 can be moved with a chassis 1 on a chassis 2 and has a forward hopper 3, behind which a primary drive source 4 is located. At the rear end of the chassis 1 is a Querverteilvorrichtung 5, for example, a worm mechanism, provided behind which a screed is 7, which is connected to the chassis 1 with arms 6. On the upper side behind the primary drive source 4, a driver's cab 8 is provided, in which a control panel B is located, in which, for example, a central processing unit Z of an electronic control device of the paver F is accommodated. To electrical subsystems of the paver runs from the control panel B, a transmission path 9. The electronic control device includes a bus system, such as a fieldbus to which several centralized or decentralized programmable logic controller and controller units, multiple centralized or decentralized IO modules, external control stations, engine electronics, generator electronics and various sensor and actuator subsystems are connected. These components of the control system are used to operate the paver for control, regulating and monitoring functions, wherein at least in a memory area of the central processing unit Z machine parameters are entered and stored in the form of data to which the electronic control device continuously falls during operation of the paver and which, if necessary, during operation for the purpose of conversion to the central search unit Z, or at a display and input section 11 of the control panel B can be changed. The machine parameters here are not only simple basic data that are useful for various road pavers, but also data that are specifically useful for only this paver and / or its installation task, for example.

Am Bedienpult B, beispielsweise in einer Rückenwand oder Unterseite (oder in der Seitenwand 10) ist an geeigneter Stelle ein Datenaustauschanschluss 12 vorgesehen, an welchem eine Datenspeichervorrichtung P abnehmbar angebracht ist. Die Datenspeichervorrichtung P enthält zumindest eine Mikrospeichereinheit, und, vorzugsweise, eine Speicherlogik.

When the central processing unit Z is replaced in a service case, the previously set machine parameters are immediately available again. When replacing the control panel B, the data storage device P is removed and reattached to the new control panel B, to immediately transmit the data of the machine parameters to the central processing unit Z again. The transmission can be either automatic, e.g. be initiated at system startup or via the display and input section 11. The data storage device P is expediently supplied as an accessory of the paver F with this to the customer.

Die Datenspeichervorrichtung P in Fig. 3 weist ein robustes, baumaschinentaugliches, beispielsweise annähernd zylindrisches, Außengehäuse 13 auf, in dem die zumindest eine Mikrospeichereinheit und gegebenenfalls die Speicherlogik untergebracht sind. Das Außengehäuse 13 kann aus Kunststoff bestehen und ist zweckmäßigerweise gegebenenfalls verstärkt und/oder abgeschirmt. An einem Ende des Außengehäuses 13 ist ein Stecker 14 angeformt, in welchem sich Anschlusskontakte 15 befinden. Ferner ist, zweckmäßigerweise, am Außengehäuse 13 eine Überwurfmutter 16 drehbar angebracht, die zur Sicherung und zum Schutz der Steckverbindung nach Anbringen der Datenspeichervorrichtung am Datenaustauschanschluss 12 verwendet wird. Die Überwurfmutter 16 bildet ein Sicherungselement und ist gegebenenfalls absperrbar.The data storage device P in FIG. 3 has a robust, suitable for construction machinery, for example approximately cylindrical, outer housing 13, in which the at least one micro-storage unit and optionally the storage logic are housed. The outer housing 13 may be made of plastic and is expediently optionally reinforced and / or shielded. At one end of the outer housing 13, a plug 14 is formed in which terminal contacts 15 are located. Further, suitably, on the outer housing 13, a cap nut 16 is rotatably mounted, which is used to secure and protect the connector after attaching the data storage device at the data exchange port 12. The union nut 16 forms a securing element and is optionally lockable.

In Fig. 4 ist eine Abdeckplatte 17 beispielsweise in der Rückenwand oder Unterwand des Bedienpults B mit Befestigungselementen 18 festgelegt. In der Abdeckplatte 17 ist der Datenaustauschanschluss 12 untergebracht, der als Steckanschluss ausgebildet ist und Steckkontakte 19 enthält. Zum Schutz der Steckkontakte und der Steckverbindung ist ein den Steckanschluss umgebender Schutzkragen 20 vorgesehen, der mit einem Außengewinde 21 für die Überwurfmutter 16 versehen ist. Gegebenenfalls wird anstelle einer Schraubverbindung ein Bajonett-Rast- oder Spannbügelverschluss zum Festlegen der Datenspeichervorrichtung P und zum Schutz und gegebenenfalls zur Abdichtung der Steckverbindung benutzt.4, a cover plate 17 is fixed, for example, in the back wall or bottom wall of the control panel B with fastening elements 18. In the cover plate 17 of the data exchange port 12 is housed, which is designed as a plug connection and plug contacts 19 contains. To protect the plug contacts and the plug connection, a protective collar 20 surrounding the plug connection is provided which is provided with an external thread 21 for the cap nut 16. Possibly Instead of a screw connection, a bayonet catch or clamp lock is used to fix the data storage device P and to protect and possibly seal the plug connection.

Fig. 5 verdeutlicht die ordnungsgemäß angebrachte Datenspeichervorrichtung P, die mit der Überwurfmutter 16 an der Abdeckplatte 17 festgelegt ist.Fig. 5 illustrates the properly attached data storage device P, which is fixed with the union nut 16 on the cover plate 17.

Bei einer alternativen Ausführungsform könnte der Datenaustauschanschluss 12 für die Datenspeichervorrichtung P an anderer, geeigneter Stelle im Führerstand 8 des Straßenfertigers F platziert sein, z.B. nahe bei der Zentralrecheneinheit Z, und gegebenenfalls an der Elektronikbox der elektronischen Steuerungsvorrichtung. Da die Maschinenparameter-Daten redundant in der passiven Datenspeichervorrichtung P gespeichert und gesichert sind, entfällt in einem Servicefall beispielsweise bei Austausch der Zentralrecheneinheit Z und/oder des Bedienpults B eine Neuparametrierung der elektronischen Steuervorrichtung, da die erforderlichen schon früher beschafften und gespeicherten Daten aus der Datenspeichervorrichtung verfügbar sind.In an alternative embodiment, the data exchange port 12 for the data storage device P could be placed at another suitable location in the cab 8 of the paver F, e.g. close to the central processing unit Z, and possibly to the electronics box of the electronic control device. Since the machine parameter data are redundantly stored and secured in the passive data storage device P, in a service case, for example when replacing the central processing unit Z and / or the control panel B, a reparameterization of the electronic control device is omitted since the required data already obtained and stored from the data storage device Are available.
