Definitions
- the invention relates to an escalator or moving walk with a device for vestibule monitoring to control the drive.
- the drive is switched off in an unused escalator.
- passengers are approaching the escalator, for example, when passing through a light barrier, a pulse is triggered and the drive is switched on. After a predetermined period of time, at the earliest after leaving the last passenger of the escalator, the drive is switched off again.
- the light barrier is spaced from the escalator and placed on separate columns. This requires an additional and unnecessary material and installation costs. Furthermore, a passenger is not necessarily passed through the photocell. A person who does not know the control system and approaching the stationary escalator from the side, can walk around the photocell, the escalator without this is turned on. This can give the disadvantageous impression of a broken or unreliable escalator.
- the Patent EP 0847956 shows arranged in the handrail deflection light sensors with transmitters and receivers, which monitor the entire vestibule of the escalator.
- This device is inconspicuous, but still visible and therefore not completely vandal-proof.
- these light sensors are misdirected from the effects of the weather and triggered, for example, in direct sunlight.
- Such sensors also require large and expensive amplifiers and evaluation electronics and can not detect the direction of movement. For example, people who walk the escalator and those who leave the escalator are treated the same. When escalators are installed in parallel, it often happens that outgoing persons erroneously cause the other escalator to start.
- An escalator or a moving walk according to the preamble of the claim is eg off DE-U-2 307 951 known.
- the invention has the object to provide an antechamber monitoring for escalators to control the drive of the type mentioned, which does not have the aforementioned disadvantages and in a simple way allows early detection of passengers, which is not misled by the weather, which completely invisible, cheaper and more compact and which recognizes the direction of a movement.
- sensors are arranged in the area of the handrail deflection, which monitor the entrance area of the escalator and which are sensitive to electromagnetic waves with a wavelength longer than 100 ⁇ m. This wavelength range is outside the light and infrared range of the electromagnetic spectrum.
- the sensors can not be misdirected by the effects of the weather, e.g. Sunlight, fog, artificial lighting, heat radiation.
- the sensors can be arranged invisibly concealed to the user as they are e.g. can be covered by a plastic cap.
- a plastic cap can stop the optical electromagnetic waves, but not the electromagnetic waves with wavelength longer than 100 ⁇ m. This makes the whole escalator much vandal-proof.
- the escalator control print can be smaller, and thereby cheaper, since no evaluation electronics and no amplifiers for the new monitoring device in this wavelength range is needed.
- a direction detection is made possible in the inventive monitoring device by the principle of evaluation of the Doppler effect. It has the advantage that only persons are recognized who approach the escalator and not those who leave the escalator, or only the wave cone or pass through. This is a great advantage in parallel installation of escalators. There it often happens that outgoing persons erroneously cause the other escalator to start.
- sensors are mounted on both sides of the escalator so that the shaft cone is symmetrical with respect to the escalator and the detection of people is carried out more precisely and accurately.
- the sensors are designed as high-frequency sensors, i. sensitive to electromagnetic wavelengths shorter than 1 m. In this wavelength range, the accuracy of the person recognition is maximized.
- FIG. 4 shows a detailed view of a second embodiment.
- the escalator 1 shows a schematic representation of an escalator 1.
- the escalator 1 has a number of stages 2, which as endless circumferential step band between two Balustradensockeln 3 are embedded.
- a balustrade 4 is constructed, on which an endless handrail 5 runs synchronously with the step belt.
- the handrail 5 is guided in each case in the balustrade base 3.
- the balustrade pedestal 3 is provided with handrail inlet caps 11.
- sensors 12 are arranged. These sensors 12 monitor the access to the escalator 1 in a certain area 13 in front of the entrance to the escalator 1, for example the area of an entrance plate 14.
- the sensors are sensitive to electromagnetic waves having a wavelength greater than 100 pm, ie outside the optical or infrared range. area.
- the sensors 12 are invisibly integrated into the handrail inlet caps 11 and each consist of a transmitter 15 and a receiver 16, preferably a planar antenna.
- Transmitter 15 and receiver 16 operate, for example, on a high frequency basis, ie at shorter wavelengths than 1 m, and respond to reflections or rejection of high frequency waves of persons and objects.
- the sensors can be radar sensors.
- the waves or high-frequency signals emitted by the transmitter 15 are reflected or reflected by the person or object and recorded by the associated receiver 16.
- This response of the sensor 12 triggers Signal from, which is processed in an electronic part not further described here and leads to start the drive of the escalator 1. If the sensors 12 fail, the escalator 1 remains in continuous operation.
- the senor 12 can be mounted only on one side in a handrail inlet cap 11.
- Transmitter 15 and receiver 16 must be aligned and dimensioned in this case so that the monitoring area 13 remains ensured as in the example described above.
- FIG 3 shows a detailed view of a bevelled handrail inlet cap 11 with a built-in sensor 12.
- the handrail inlet cap 11 serving as a connection of the base is inclined both towards the base end and towards the step band. This results in the user of the escalator facing surface 11 '.

- the assembly is simplified by the mounting of the sensor 12 on the back of the handrail inlet cap 11. A fitting in mounting holes of the base is not required.
- Desweitern 11 further controls, such as an emergency stop switch 20 can be arranged in the robust handrail cap. Likewise, the installation and material costs are kept very low by this arrangement of the sensors 12, since during installation no additional, away from the actual escalator 1 or the balustrade base 3 lines must be wired or wired.
- FIG. 4 shows a second embodiment of an inventive Anteroom monitoring for an escalator 1 or a moving walkway.
- the monitoring device is not visible to the user, as no holes in the plastic cap are visible. This makes the whole escalator much vandal-proof because no recesses can be sealed with chewing gum.
- the new built-in part of the monitoring device can only be used with plastic caps, the permeability for the electromagnetic waves being given in the wavelength range given above. Of metal parts, the electromagnetic waves would be disturbed or distracted or stopped. So with sheet steel or Nirosta - front (front) plates, this monitoring device does not work because the electromagnetic waves do not penetrate the metal.
- the monitoring device can be misguided by any weather conditions, since it disappears behind the protective plastic cap.
- the conventional vestibule monitoring however, triggered in direct sunlight and then the escalator started.
- the escalator control print becomes smaller, and thereby cheaper, since no evaluation electronics and no amplifiers are needed for the new monitoring device.
- An evaluation is but advantageously provided which is integrated in the small monitor (3-pin cable) and which allows the direction detection of the movement of an object by the principle of the Doppler effect.

Abstract
Description
Die Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig mit einer Einrichtung zur Vorraumüberwachung zur Steuerung des Antriebes.The invention relates to an escalator or moving walk with a device for vestibule monitoring to control the drive.
Bei bekannten Steuerungen für Fahrtreppen wird der Antrieb bei einer unbenutzten Fahrtreppe ausgeschaltet. Nähern sich Fahrgäste der Fahrtreppe, so wird zum Beispiel beim Durchschreiten einer Lichtschranke ein Impuls ausgelöst und der Antrieb eingeschaltet. Nach Ablauf einer vorgegebenen Zeitdauer, frühestens nach Verlassen des letzten Fahrgastes der Fahrtreppe wird der Antrieb wieder abgeschaltet.In known controllers for escalators, the drive is switched off in an unused escalator. When passengers are approaching the escalator, for example, when passing through a light barrier, a pulse is triggered and the drive is switched on. After a predetermined period of time, at the earliest after leaving the last passenger of the escalator, the drive is switched off again.
Beispielsweise ist aus der
Bei der vorstehend beschriebenen Lösung wird die Lichtschranke von der Fahrtreppe distanziert auf separaten Säulen angeordnet. Dies erfordert einen zusätzlichen und unnötigen Material- und Installationsaufwand. Desweitern wird ein Fahrgast nicht zwingend durch die Lichtschranke geleitet. Eine Person, die das Steuerungssystem nicht kennt und sich der stehenden Fahrtreppe von der Seite her nähert, kann durch umgehen der Lichtschranke die Fahrtreppe betreten, ohne das diese eingeschaltet wird. Dies kann den nachteiligen Eindruck einer defekten oder unzuverlässigen Fahrtreppe erwecken.In the above-described solution, the light barrier is spaced from the escalator and placed on separate columns. This requires an additional and unnecessary material and installation costs. Furthermore, a passenger is not necessarily passed through the photocell. A person who does not know the control system and approaching the stationary escalator from the side, can walk around the photocell, the escalator without this is turned on. This can give the disadvantageous impression of a broken or unreliable escalator.
Weiter ist mit der
Eine Betriebsart wie bereits oben beschrieben ist durch diese Lichtschranke nicht mehr möglich. Betritt ein Fahrgast die stehende Fahrtreppe und durchbricht auf Höhe der Handlaufumlenkung die Lichtschranke würde dadurch der Antrieb eingeschaltet. In diesem Fall entsteht ein unangenehmer, möglicherweise sogar gefährlicher und dadurch dem Fahrgast unzumutbarer Zustand, da dieser beim Anfahren bereits auf den Stufen der Fahrtreppe steht. Desweitern ist auch bei dieser Lösung eine zusätzliche Paneele notwendig um Bauteile, wie die Lichtschranke, unterzubringen. Diese Paneele mindert zudem die Optik der möglicherweise aus Glas bestehenden Balustrade und bietet praktisch keinen Schutz gegen Vandalismus.An operating mode as described above is no longer possible by this light barrier. If a passenger steps on the stationary escalator and breaks through the photocell at the height of the handrail deflection, the drive would be switched on. In this case, an unpleasant, possibly even dangerous and thus the passenger unacceptable condition arises because it is already on the steps of the escalator when starting. Furthermore, with this solution, an additional panel is necessary to accommodate components such as the light barrier. This panel also reduces the appearance of the possibly existing balustrade glass and offers virtually no protection against vandalism.
Das
Eine Fahrtreppe oder ein Fahrsteig gemäß dem Oberbegriff des Anspruchs ist z.B. aus
Der Erfindung liegt die Aufgabe zugrunde eine Vorraumüberwachung für Fahrtreppen zur Steuerung des Antriebes der eingangs genannten Art vorzuschlagen, welche die vorgenannten Nachteile nicht aufweist und auf einfache Art und Weise ein frühzeitiges Erkennen von Fahrgästen ermöglicht, welche nicht von Witterungseinflüssen fehlgeleitet wird, welche vollkommen unsichtbar, billiger und kompakter ist und welche die Richtung einer Bewegung erkennt.The invention has the object to provide an antechamber monitoring for escalators to control the drive of the type mentioned, which does not have the aforementioned disadvantages and in a simple way allows early detection of passengers, which is not misled by the weather, which completely invisible, cheaper and more compact and which recognizes the direction of a movement.
Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in claim 1.
Wie bisher werden im Bereich der Handlaufumlenkung Sensoren angeordnet, welche den Eingangsbereich der Fahrtreppe überwachen und welche für elektromagnetische Wellen mit Wellenlänge länger als 100 µm empfindlich sind. Dieser Wellenlängebereich liegt ausserhalb des Licht- und Infrarot-Bereiches des elektromagnetischen Spektrums.As before, sensors are arranged in the area of the handrail deflection, which monitor the entrance area of the escalator and which are sensitive to electromagnetic waves with a wavelength longer than 100 μm. This wavelength range is outside the light and infrared range of the electromagnetic spectrum.
Die erreichten Vorteile sind darum im wesentlichen darin zu sehen, dass die Sensoren nicht durch Witterungseinflüsse fehlgeleitet werden können, wie z.B. Sonnenlicht, Nebel, künstliche Beleuchtung, Wärmestrahlung.The advantages achieved are therefore essentially that the sensors can not be misdirected by the effects of the weather, e.g. Sunlight, fog, artificial lighting, heat radiation.
Durch die Erfindung erreichte Vorteile sind, dass die Sensoren für den Benutzer vollkommen unsichtbar verdeckt bzw. dissimuliert angeordnet werden können, da sie z.B. durch eine Kunststoffkappe bedeckt werden können. Eine solche Kappe kann die optischen elektromagnetischen Wellen anhalten, aber nicht die elektromagnetischen Wellen mit Wellenlänge länger als 100 µm. Dadurch wird die ganze Fahrtreppe viel vandalensicherer.Advantages achieved by the invention are that the sensors can be arranged invisibly concealed to the user as they are e.g. can be covered by a plastic cap. Such a cap can stop the optical electromagnetic waves, but not the electromagnetic waves with wavelength longer than 100 μm. This makes the whole escalator much vandal-proof.
Des weiteren kann der Fahrtreppensteuerungsprint kleiner werden, und dadurch billiger, da keine Auswertelektronik und keine Verstärker für die neue Überwachungseinrichtung bei diesem Wellenlängebereich benötigt wird.Furthermore, the escalator control print can be smaller, and thereby cheaper, since no evaluation electronics and no amplifiers for the new monitoring device in this wavelength range is needed.
Eine Richtungserkennung wird bei der erfindungsgemässen Überwachungseinrichtung durch das Prinzip der Auswertung des Dopplereffekts ermöglicht. Sie bietet den Vorteil, dass nur Personen erkannt werden, die auf die Fahrtreppe zugehen und nicht solche die die Fahrtreppe verlassen, oder nur den Wellenkegel streifen bzw. durchschreiten. Das ist ein grosser Vorteil bei Parallelaufstellung von Fahrtreppen. Dort kommt es oft vor, dass abgehende Personen irrtümlicherweise die andere Fahrtreppe zum Losstarten veranlassen.A direction detection is made possible in the inventive monitoring device by the principle of evaluation of the Doppler effect. It has the advantage that only persons are recognized who approach the escalator and not those who leave the escalator, or only the wave cone or pass through. This is a great advantage in parallel installation of escalators. There it often happens that outgoing persons erroneously cause the other escalator to start.
Vorteilweise werden Sensoren auf beiden Seiten der Fahrtreppe angebracht, damit der Wellenkegel symmetrisch gegenüber der Fahrtreppe ist und die Erkennung von Personen präziser und genauer ausgeführt wird.Advantageously, sensors are mounted on both sides of the escalator so that the shaft cone is symmetrical with respect to the escalator and the detection of people is carried out more precisely and accurately.
Vorteilweise werden die Sensoren als Hochfrequenzsensoren ausgebildet, d.h. empfindlich für elektromagnetische Wellenlängen kürzer als 1 m. In diesem Wellenlängebereich wird die Genauigkeit der Personenerkennung maximiert.Advantageously, the sensors are designed as high-frequency sensors, i. sensitive to electromagnetic wavelengths shorter than 1 m. In this wavelength range, the accuracy of the person recognition is maximized.
Durch die in den Unteransprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Vorraumüberwachung für Fahrtreppen möglich. Durch die unauffällige Anordnung der Sensoren werden Beschädigungen durch Vandalismus oder auch unbeabsichtigt, weitgehendst vermieden. Der optische Eindruck der Fahrtreppe bleibt unverändert. Zudem sind keine zusätzlichen Bauelemente an der Balustrade oder im Vorraum mehr notwendig.The measures listed in the dependent claims advantageous refinements and improvements of the claim 1 vestibule monitoring for escalators are possible. The inconspicuous arrangement of the sensors damages by vandalism or unintentionally, largely avoided. The optical impression of the escalator remains unchanged. In addition, no additional components on the balustrade or in the anteroom more necessary.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt und im folgenden näher erläutert. Es zeigen:In the drawing, two embodiments of the invention are illustrated and explained in more detail below. Show it:
Fig.1 eine schematische Darstellung einer Fahrtreppe mit Ausschnittsvergrösserung,1 is a schematic representation of an escalator with excerpt enlargement,
Fig.2 einen Ausschnitt des Grundrisses einer Fahrtreppe im Bereich der Antrittsplatte,2 shows a detail of the outline of an escalator in the region of the starting plate,
Fig.3 eine detaillierte Ansicht eines ersten Ausführungsbeispiels, und3 shows a detailed view of a first embodiment, and
Fig.4 eine detaillierte Ansicht eines zweiten Ausführungsbeispiels.4 shows a detailed view of a second embodiment.
Fig.1 zeigt eine schematische Darstellung einer Fahrtreppe 1. Die Fahrtreppe 1 weist eine Anzahl Stufen 2 auf, welche als endlos umlaufendes Stufenband zwischen zwei Balustradensockeln 3 eingebettet sind. Auf jedem Balustradensockel 3 ist eine Balustrade 4 aufgebaut, auf der ein endloser Handlauf 5 synchron mit dem Stufenband läuft. Im unteren Teil einer Handlaufumlenkung 10 wird der Handlauf 5 jeweils in den Balustradensockel 3 geführt. In diesem Bereich ist der Balustradensockel 3 mit Handlaufeinlaufkappen 11 versehen. An diesen Handlaufeinlaufkappen 11 sind Sensoren 12 angeordnet. Diese Sensoren 12 überwachen den Zugang zur Fahrtreppe 1 in einem bestimmten Bereich 13 vor dem Eingang zur Fahrtreppe 1, beispielsweise den Bereich einer Antrittsplatte 14. Die Sensoren sind empfindlich für elektromagnetische Wellen mit einer Wellenlänge grösser als 100 pm, d.h. ausserhalb des optischen oder Infrarot- Bereiches.1 shows a schematic representation of an escalator 1. The escalator 1 has a number of
Die besten Resultate wurden mit einer Wellenlänge von 12,5 mm erreicht, die einer Frequenz von 24 GHz entspricht. Der ganze Wellenlängebereich zwischen 1 mm und 100 mm ist aber sehr geeignet für diese Anwendung. In dem Ausschnitt ist ein Teil der seitlichen Sockelverkleidung weggebrochen. Der von aussen nicht sichtbare innerhalb des Sockels angebrachte Sensor 12 ist oberhalb der Bruchlinie sichtbar.The best results were achieved with a wavelength of 12.5 mm, which corresponds to a frequency of 24 GHz. The whole wavelength range between 1 mm and 100 mm is very suitable for this application. In the cutout a part of the side skirting is broken away. The not visible from the outside mounted inside the
Fig.2 zeigt einen Ausschnitt des Grundrisses der Fahrtreppe 1 im Bereich der Antrittsplatte 14. Die Sensoren 12 sind in die Handlaufeinlaufkappen 11 unsichtbar integriert und bestehen jeweils aus einem Sender 15 und einem Empfänger 16, vorzugsweise einer Planar-Antenne. Sender 15 und Empfänger 16 arbeiten beispielsweise auf Hochfrequenzbasis, d.h. bei kürzeren Wellenlängen als 1 m, und sprechen auf Reflexionen bzw. Zurückwerfen von Hochfrequenzwellen von Personen und Gegenständen an. Die Sensoren können Radarsensoren sein. Beim Betreten des Überwachungsbereiches 13 eines Sensors 12 werden die vom Sender 15 ausgesendeten Wellen bzw. Hochfrequenzsignale durch die Person oder den Gegenstand reflektiert bzw. zurückgeworfen und vom zugehörigen Empfänger 16 aufgenommen. Dieses Ansprechen des Sensors 12 löst ein Signal aus, das in einem hier nicht weiter beschriebenen Elektronikteil verarbeitet wird und zum Starten des Antriebes der Fahrtreppe 1 führt. Sollten die Sensoren 12 ausfallen, so verbleibt die Fahrtreppe 1 im Dauerbetrieb.2 shows a section of the outline of the escalator 1 in the region of the starting
Als weitere Ausführungsvariante kann der Sensor 12 nur auf einer Seite in einer Handlaufeinlaufkappe 11 angebracht werden. Sender 15 und Empfänger 16 müssen in diesem Fall so ausgerichtet und dimensioniert werden, dass der Überwachungsbereich 13 wie im oben beschriebenen Beispiel gewährleistet bleibt.As a further embodiment, the
Fig.3 zeigt eine detaillierte Ansicht einer abgeschrägten Handlaufeinlaufkappe 11 mit einem eingebauten Sensor 12. Die als Anschluss des Sockels dienende Handlaufeinlaufkappe 11 ist sowohl zum Sockelende hin als auch zum Stufenband hin geneigt. Damit ergibt sich eine dem Benutzer der Fahrtreppe zugewandte Fläche 11'. Der Sensor 12 ist innerhalb der Handlaufeinlaufkappe 11 montiert. Sender 15 und Empfänger 16 werden so in die Handlaufeinlaufkappe 11 integriert, dass sie dem Benutzer vollständig verborgen und unsichtbar bleiben. Dies hat den Vorteil, dass Beschädigungen am Sensor 12 durch Vandalismus oder aus Absicht, praktisch ausgeschlossen werden kann. Ausserdem wird durch die Montage des Sensors 12 auf die Rückseite der Handlaufeinlaufkappe 11 die Fertigung vereinfacht. Ein Einpassen in Montageöffnungen des Sockels ist nicht erforderlich. Desweitern können in der robusten Handlaufeinlaufkappe 11 weitere Bedienungselemente, wie beispielsweise ein Nothaltschalter 20, angeordnet werden. Ebenso wird durch diese Anordnung der Sensoren 12 der Installations- und Materialaufwand sehr gering gehalten, da bei der Montage keine zusätzlichen, von der eigentlichen Fahrtreppe 1 oder vom Balustradensockel 3 wegführenden Leitungen verlegt oder verdrahtet werden müssen.3 shows a detailed view of a bevelled
Fig.4 zeigt ein zweites Ausführungsbeispiel einer erfindungsgemässen Vorraumüberwachung für eine Fahrtreppe 1 oder eines Fahrsteiges. Dabei werden die Sensoren 12 mit Sender 15 und Empfänger 16, rechts oder links des Handlaufs 5 im Bereich der Handlaufumlenkung 10 verdeckt in der Balustrade 4 angeordnet. Die Funktionsweise ist dieselbe wie beim oben beschriebenen Ausführungsbeispiel.4 shows a second embodiment of an inventive Anteroom monitoring for an escalator 1 or a moving walkway. The
Die Überwachungseinrichtung ist für den Benutzer nicht sichtbar, da keine Löcher in der Kunststoffkappe sichtbar sind. Dadurch wird die ganze Fahrtreppe viel vandalensicherer, weil keine Ausnehmungen mit Kaugummi zugeklebt werden können. Das neue Einbauteil der Überwachungseinrichtung ist nur bei Kunststoffkappen verwendbar, wobei die Durchlässigkeit für die elektromagnetischen Wellen in dem oben angegebenen Wellenlängebereich gegeben ist. Von Metallteilen würden die elektromagnetischen Wellen gestört bzw. abgelenkt bzw. aufgehalten werden. Also bei Stahlblech- oder Nirosta - Stirn(front)platten funktioniert diese Überwachungseinrichtung nicht, da die elektromagnetischen Wellen das Metall nicht durchdringen.The monitoring device is not visible to the user, as no holes in the plastic cap are visible. This makes the whole escalator much vandal-proof because no recesses can be sealed with chewing gum. The new built-in part of the monitoring device can only be used with plastic caps, the permeability for the electromagnetic waves being given in the wavelength range given above. Of metal parts, the electromagnetic waves would be disturbed or distracted or stopped. So with sheet steel or Nirosta - front (front) plates, this monitoring device does not work because the electromagnetic waves do not penetrate the metal.
Weiters kann die Überwachungseinrichtung von keinen Witterungseinflüssen fehlgeleitet werden, da sie hinter der schützenden Kunststoffkappe verschwindet. Die herkömmliche Vorraumüberwachung wird hingegen bei direkter Sonnenlichteinstrahlung ausgelöst und daraufhin die Fahrtreppe gestartet.Furthermore, the monitoring device can be misguided by any weather conditions, since it disappears behind the protective plastic cap. The conventional vestibule monitoring, however, triggered in direct sunlight and then the escalator started.
Des weiteren wird der Fahrtreppensteuerungsprint kleiner, und dadurch billiger, da keine Auswertelektronik und keine Verstärker für die neue Überwachungseinrichtung benötigt werden.Furthermore, the escalator control print becomes smaller, and thereby cheaper, since no evaluation electronics and no amplifiers are needed for the new monitoring device.
Eine Auswerteelektronik wird aber vorteilhafterweise vorgesehen, welche im kleinen Überwachungsgerät integriert (3poliges Kabel) wird und welche die Richtungserkennung der Bewegung eines Objektes durch das Prinzip des Dopplereffektes ermöglicht.An evaluation is but advantageously provided which is integrated in the small monitor (3-pin cable) and which allows the direction detection of the movement of an object by the principle of the Doppler effect.
Sie bietet den Vorteil, dass nur Personen erkannt werden, die auf die Fahrtreppe zugehen und nicht solche die die Fahrtreppe verlassen, oder nur den Radarwellenkegel streifen bzw. durchschreiten. Das ist ein grosser Vorteil vor allem bei Parallelaufstellung von Fahrtreppen. Dort kommt es oft vor, dass abgehende Personen irrtümlicherweise die andere Fahrtreppe zum Losstarten veranlassen.It has the advantage that only people who are on the Escalator approach and not those who leave the escalator, or just the Radarwellenkegel strip or pass. This is a great advantage, especially with parallel installation of escalators. There it often happens that outgoing persons erroneously cause the other escalator to start.
