Demgegenüber ist die Umkehrstation im Bereich eines zweiten Endes der Personenbeförderungsanlage angeordnet und weist eine Master-Steuereinheit auf. Zum Austausch von Daten sind die Master-Steuereinheit und die Slave-Steuereinheit durch einen Datenbus miteinander verbunden. Weiterhin weist die Slave-Steuereinheit eine erste Leiterplatte auf, die mit einem ersten Satz elektronischer Bauteile versehen ist und zur Übermittlung von die Funktion der Personenbeförderungsanlage betreffenden Daten an die Master-Steuereinheit dient. Die Master-Steuereinheit weist eine zweite Leiterplatte auf, die mit einem zweiten Satz elektronischer Bauteile versehen ist und zur Auswertung der Daten und Steuerung der Personenbeförderungsanlage dient.The present invention relates to a passenger transport system, in particular an escalator or moving walk, with a circulating belt, a drive station and a reversing station. The drive station is arranged in the region of a first end of the passenger transport installation and has a slave control unit. In contrast, the reversing station is arranged in the region of a second end of the passenger transport system and has a master control unit. For exchanging data, the master control unit and the slave control unit are interconnected by a data bus. Furthermore, the slave control unit has a first printed circuit board which is provided with a first set of electronic components and serves for the transmission of data relating to the function of the passenger transport installation to the master control unit.

In einer Treppe können auch mehrere Slaves eingesetzt werden.
Die Position des Masters ist nicht auf den unteren Treppenkopf beschränkt. Bei einer Anlage mit externen Schaltschrank ist der Master im externen Schaltschrank platziert. Im unteren und oberen Treppenkopf sind jeweils ein Slave platziert.In a staircase, several slaves can be used.
The position of the master is not limited to the lower stairwell. In a system with an external control cabinet, the master is placed in the external control cabinet. In each case a slave is placed in the lower and upper stairs.

Zum Betrieb und zur Überwachung herkömmlicher Fahrtreppen ist es bekannt diese mit einem Steuerungssystem auszustatten, das im Bereich der Antriebsstation eine so genannte Slave-Steuereinheit und im Bereich der Umkehrstation eine so genannte Master-Steuereinheit umfasst. Anhand der Definition als "Master" beziehungsweise "Slave" wird ersichtlich, dass die Slave-Steuereinheit vorrangig dafür vorgesehen ist Daten von den mit der Slave-Steuereinheit in Verbindung stehenden Peripheriegeräten, wie beispielsweise Sensoren, zu sammeln und an die Master-Steuereinheit zu übermitteln. Ferner ist die Slave-Steuereinheit eingerichtet, um von der Master-Steuereinheit abgegebene Steuerbefehle in Form von Steuersignalen zu empfangen und an die Peripheriegeräte weiterzugeben, wodurch beispielsweise ein an die Slave-Steuereinheit angeschlossenes Relais einer Fahrtrichtungsanzeige gesteuert werden kann. Die Master-Steuereinheit wird hauptsächlich für den Empfang der von der Slave-Steuereinheit übermittelten Daten, zur Auswertung der Daten und zur Steuerung der gesamten Fahrtreppe, insbesondere zur Steuerung der an die Master-Steuereinheit und die Slave-Steuereinheit angeschlossenen Peripheriegeräte verwendet. Aufgrund dieser unterschiedlichen Funktionen und Einsatzbereiche der Master-Steuereinheit und der Slave-Steuereinheit ergeben sich zwangsweise unterschiedliche Anforderungen an deren einzelne Bauteile. Dies wirkt sich insbesondere auf die elektronische Bauteile tragende Leiterplatten der Master-Steuereinheit und Slave-Steuereinheit aus und erweist sich insbesondere dann als nachteilig, wenn Slave-Steuereinheiten mit unterschiedlichen Anforderungsprofilen eingesetzt werden. Somit ergibt sich insbesondere im Hinblick auf eine Massenproduktion der Leiterplatten ein vergleichsweise hoher Kostenaufwand.For the operation and monitoring of conventional escalators, it is known to equip them with a control system comprising a so-called slave control unit in the area of the drive station and a so-called master control unit in the area of the reversing station. Based on As a "master" or "slave", it will be appreciated that the slave controller is primarily intended to collect data from peripheral devices, such as sensors, associated with the slave controller, and transmit it to the master controller. Further, the slave control unit is arranged to receive control commands issued from the master control unit in the form of control signals and relay them to the peripheral devices, whereby, for example, a turn signal indicator relay connected to the slave control unit can be controlled. The master control unit is mainly used for receiving the data transmitted from the slave control unit, for evaluating the data and for controlling the entire escalator, in particular for controlling the peripherals connected to the master control unit and the slave control unit. Due to these different functions and areas of application of the master control unit and the slave control unit, forcing different demands on their individual components. This has an effect, in particular, on the electronic components-carrying printed circuit boards of the master control unit and slave control unit and proves to be disadvantageous, in particular, when slave control units with different requirement profiles are used. This results in a comparatively high cost, in particular with regard to mass production of the printed circuit boards.

Der Erfindung liegt die Aufgabe zu Grunde, eine Personenbeförderungsanlage zu schaffen, bei der durch eine Vereinheitlichung der Bestandteile des Steuerungssystems eine Kostenersparnis bei der Herstellung dieser Bestandteile erzielt werden kann.The invention is based on the object to provide a passenger transport system, in which a cost savings in the production of these components can be achieved by standardizing the components of the control system.

Zur Lösung dieser Aufgabe ist eine Personenbeförderungsanlage mit den eingangs genannten Merkmalen in Übereinstimmung mit Anspruch 1 erfindungsgemäß dadurch gekennzeichnet, dass die erste Leiterplatte und die zweite Leiterplatte einen identischen Aufbau haben. Die erfindungsgemäße Personenbeförderungsanlage beruht auf der Erkenntnis, dass sowohl für die z.B. in der Antriebsstation angeordnete Slave-Steuereinheit als auch für die z.B. in der Umkehrstation angeordnete Master-Steuereinheit eine einheitliche Leiterplatte eingesetzt werden kann. Dies vereinfacht die Herstellung der Leiterplatten für die Personenbeförderungsanlage, wodurch eine Kostenersparnis erzielt werden kann. Weiterhin führt dies zu einer Vereinfachung beim Zusammenbau der Master-Steuereinheit und der Slave-Steuereinheit, da keine unterschiedlichen Leiterplatten herangezogen werden müssen, wodurch eine Verwechslung der Leiterplatten ausgeschlossen werden kann. Gleichermaßen werden auch Reparaturmaßnahmen vereinfacht, da ein falscher Austausch nicht mehr möglich ist und eine Bereithaltung verschiedener Leiterplattentypen nicht mehr erforderlich ist. Besonders vorteilhaft erweist es sich, dass die in der Regel mit einer Speichereinheit ausgestattete Leiterplatte im Falle des Austausches schnell und mit einfachen Mitteln mit den Betriebsdaten der Personenbeförderungsanlage dadurch versehen werden kann, dass die auf der Leiterplatte der anderen Steuereinheit gespeicherten Daten über den Datenbus auf die neu eingebaute Leiterplatte der Slave-Steuereinheit übertragen werden. Zudem wird dadurch eine zusätzliche Sicherheitsmaßnahme geschaffen.To solve this problem, a passenger transport system with the features mentioned in accordance with claim 1 according to the invention, characterized in that the first circuit board and the second circuit board have an identical structure. The inventive Passenger conveyor system is based on the knowledge that both for example arranged in the drive station slave control unit as well as for example arranged in the reversing station master control unit a uniform circuit board can be used. This simplifies the production of printed circuit boards for the passenger transport system, whereby a cost savings can be achieved. Furthermore, this leads to a simplification in the assembly of the master control unit and the slave control unit, since no different circuit boards must be used, whereby a confusion of the circuit boards can be excluded. Likewise, repair measures are simplified, as a wrong exchange is no longer possible and a provision of different types of PCBs is no longer required. It proves to be particularly advantageous that the printed circuit board, which is usually equipped with a memory unit, can be quickly and easily provided with the operating data of the passenger conveyor system in the event of replacement by virtue of the data stored on the circuit board of the other control unit being transferred to the data bus newly installed circuit board of the slave control unit to be transferred. In addition, this creates an additional security measure.

Vorteilhafte Ausgestaltungen der erfindungsgemäßen Personenbeförderungsanlage sind in den Ansprüchen 2 bis 9 beschrieben.Advantageous embodiments of passenger transport system according to the invention are described in claims 2 to 9.

Eine bevorzugte Ausführungsform besteht darin, dass der erste Satz elektronischer Bauteile und der zweite Satz elektronischer Bauteile mindestens teilweise identisch ausgebildet sind. Mit anderen Worten können neben dem gleichen Aufbau der ersten und zweiten Leiterplatte auch weitgehend alle elektronischen Bauteile der wenigstens zwei Leiterplatten identisch sein, um so eine weitere Vereinheitlichung der Bestandteile des Steuerungssystems der Personenbeförderungsanlage zu erreichen. Daraus lässt sich wiederum eine Vereinfachung bei der Herstellung und somit eine Kostenersparnis erzielen. So kann beispielsweise vorgesehen sein, dass eine bestimmte Anzahl von Bauteilen bei der ersten und zweiten Leiterplatte identisch ausgebildet sind und an den gleichen Steckplätzen der identisch ausgebildeten ersten und zweiten Leiterplatte aufgebracht sind.A preferred embodiment is that the first set of electronic components and the second set of electronic components are at least partially identical. In other words, in addition to the same structure of the first and second printed circuit board also largely all electronic components of the at least two circuit boards may be identical, so as to achieve a further standardization of the components of the control system of passenger transport system. This in turn can be a simplification in the production and thus achieve a cost savings. For example, it may be provided that a certain number of components in the first and second circuit board are formed identically and are applied to the same slots of the identically formed first and second circuit board.

Eine weitere bevorzugte Ausführungsform besteht darin, dass die Leiterplatten mit einem Schalter versehen sind, wobei die Leiterplatten in Abhängigkeit von der Stellung des Schalters als Master-Steuereinheit oder als Slave-Steuereinheit konfigurierbar sind. Dieser Schalter wird vorzugsweise manuell und vor Ort betätigt, das heißt bei einer Installation oder im Rahmen einer Reparatur.A further preferred embodiment is that the circuit boards are provided with a switch, wherein the circuit boards are configurable depending on the position of the switch as a master control unit or as a slave control unit. This switch is preferably operated manually and locally, that is, during installation or as part of a repair.

Zweckmäßigerweise weisen die Leiterplatten eine erste optische Anzeigeeinheit zur Anzeige der Konfiguration als Master-Steuereinheit oder als Slave-Steuereinheit auf. Dies vereinfacht in schlecht einsehbaren oder wenig beleuchteten Bereichen das Erkennen der Stellung des Schalters und kann auch als zusätzliches Erkennungsmittel neben dem Schalter dienen.Expediently, the printed circuit boards have a first optical display unit for displaying the configuration as a master control unit or as a slave control unit. This simplifies recognizing the position of the switch in poorly visible or poorly illuminated areas and can also serve as an additional detection means next to the switch.

Bevorzugterweise weisen die Leiterplatten eine zweite optische Anzeigeeinheit zur Anzeige von Daten, insbesondere von Fehlermeldungen, auf. Als Anzeigeeinheit wird insbesondere ein LCD-Display verwendet. So kann auch ohne Anschluss eines Auswertegerätes, wie beispielsweise eines Laptops, erkannt werden, um welche Fehlermeldung oder Fehlercode es sich handelt. Neben Fehlermeldungen können auch andere Daten, wie beispielsweise der Betriebsstatus, angezeigt werden. Ferner kann die Anzeigeeinheit auch als Echtzeituhr dienen.The printed circuit boards preferably have a second optical display unit for displaying data, in particular error messages. As a display unit, an LCD display is used in particular. Thus, even without connecting an evaluation device, such as a laptop, can be detected, which error message or error code is. In addition to error messages, other data, such as the operating status, can also be displayed. Furthermore, the display unit can also serve as a real-time clock.

Gemäß einer weiteren bevorzugten Ausführungsform weisen die Leiterplatten wenigstens eine Schnittstelle zum Anschluss eines Peripheriegerätes, insbesondere eines Laptops, auf. Dies ermöglicht insbesondere im Hinblick auf Wartungszwecke eine schnelle Ermittlung der Fehlerquelle. Zudem kann der ermittelte Fehler unter Umständen bereits softwaretechnisch mit Hilfe des angeschlossenen Laptops behoben werden.According to a further preferred embodiment, the printed circuit boards have at least one interface for connecting a peripheral device, in particular a laptop. This allows a quick determination of the error source, in particular with regard to maintenance purposes. In addition, the detected error may already be remedied by software using the connected laptop.

Die Slave-Steuereinheit und/oder die Master-Steuereinheit können zur Überwachung der Fahrgeschwindigkeit, der Fahrtrichtung, den Sicherheitsschalter oder des Bremsweges des Bandes verwendet werden. Als weitere Funktionen der Personenbeförderungsanlage kann auch der Synchronlauf der Handläufe, die Anwesenheit von Stufen oder Paletten, die Funktionsfähigkeit des Sicherheitskreises, die Schützabfallkontrolle und die Funktionsfähigkeit von Lichtschranken überwacht werden.The slave control unit and / or the master control unit may be used to monitor the vehicle speed, the direction of travel, the safety switch or the braking distance of the belt. As further functions of the passenger transport system, the synchronous operation of the handrails, the presence of steps or pallets, the functionality of the safety circuit, the contactor waste control and the functionality of photoelectric sensors can be monitored.

Gemäß einer weiteren Ausführungsform weist die Antriebsstation eine Antriebseinheit auf, wobei die Master-Steuereinheit ein Bremssignal an die Antriebseinheit übermittelt, wenn die Slave-Steuereinheit oder die Master-Steuereinheit einen Fehler detektiert. Weiterhin ist es von Vorteil, wenn die Master-Steuereinheit in vorgegebenen Zeiträumen ein Prüfsignal zur Überprüfung der Funktion des Datenbusses aussendet.According to a further embodiment, the drive station has a drive unit, wherein the master control unit transmits a brake signal to the drive unit when the slave control unit or the master control unit detects an error. Furthermore, it is advantageous if the master control unit emits a test signal for checking the function of the data bus in predetermined periods of time.
