Definitions
- the present invention relates to a passenger lift system which is protected by an access control against unauthorized use.
- passenger lift systems have a person-carrying unit and a drive for this person-carrying unit, wherein the drive is assigned an access control, in particular upstream, upstream or downstream.
- a passenger lift system is a stairlift.
- Conventional stairlifts often have a lock as access control, which in the closed state prevents the operation of the travel-controlling element (for example a joystick) of the stairlift. With a key, authorized persons can open the lock and then use and operate the stairlift.
- the travel-controlling element for example a joystick
- the present invention has set itself the task of developing a passenger lift system so that the disadvantages of the prior art are overcome. In particular, a complicate access to the release of a provided with access control passenger lift system should be made possible.
- the person lift system has a radio field generator which generates a spatially limited effect field in the area of the person carrying unit, a radio control unit which can be introduced into the stray field, and an activator which in response to an effective introduction of the control unit in the stray field Access control switches, in particular drives ready switched.
- the present invention provides a radio system-based access control for a passenger lift that operates without contact and remotely controls the activator for switching access control. It could also be said that the invention provides an approach release for a passenger lift system which in particular no longer requires any mechanical actuation.
- the advantage lies in the fact that even people with disabilities or motor disabilities, for which such Passenger lift systems are often specifically provided, easily overcome the access control of such a lift system, so can unlock the lift system for use. They have nothing to do but carry the radio control unit with them, since they can automatically cause the activation of the drive or the access control when approaching the passenger lift system or to the activator and the radio field generator. A person with access authorization must therefore simply go into or on the person carrying unit and can start transport immediately, while unauthorized persons can not make use of the passenger lift system. All this happens in a completely automated manner and without any special demands on the handling skills of the user.
- a passenger lift system in accordance with the present invention is therefore also classified as being stationary in its overall configuration and allowing only transport within this overall arrangement, especially short haul transport (over distances of, for example, about 1m-15m, for longer periods) Lift systems or belts also up to 100m or on this scale).
- the drive of a passenger lift system may be a manual drive (eg a crank drive) or a power-assisted drive, in particular an electrical, a mechanical, a hydraulic or a pneumatic drive or a hybrid form of these drives.
- a manual drive eg a crank drive
- a power-assisted drive in particular an electrical, a mechanical, a hydraulic or a pneumatic drive or a hybrid form of these drives.
- An example of a passive drive element would be a claw on a person carrying device that can engage or snap into an externally driven track or treadmill.
- An example of an active drive element would be a mounted on the person carrying unit engine with a propulsion element, such as a drive roller and possibly a gearbox connected therebetween.
- any switchable element or adjustable element is suitable for access control, which may make movement or operation of the passenger lift system impossible or impossible.
- the radio field generator and the activator can be a single component or combined in one component. Of course, it is also possible to provide them as separate units and accommodate them in a single or multiple housings.
- the common or adjacent housing saves signal paths, while a separation may possibly result in a space saving or a better utilization of free spaces.
- the radio generator field may be a stray field with an effective distance from the activator in the range of 0.25 m to 5 m. Especially advantageous ranges are from 1 m to 3 m or from 1 m to 2 m. Also ranges from 0 to 1 m can be advantageous. The choice depends on the application and the benefits to be achieved met. If you want to prevent, for example, that the activation already takes place when the one authorized person with a transmitter unit in a wider environment, you can limit the effectiveness radius, for example, up to 1m or up to 2m.
- the known RFID transponders and field generators can be used, as are known, for example, from theft prevention systems in department stores.
- the radio control unit has at least one additional switch for remote control of the access control supported by the access control, wherein the auxiliary switch for sending an operation signal is formed by a transmitter on the control unit.
- the automatic proximity release can still add a manual and separate release, which extends the scope of the present invention even more.
- the range of the transmitter on the control unit can advantageously be greater than the effective dimension of the stray field, in particular at least 1.5 times, be 2 times or 3 times this dimension, especially in a range of 3 to 20m and even up to 100m (eg for conveyor belts).
- the switching signals for the access control bring about targeted, individual access authorizations.
- exactly one radio control unit with a triggering protocol can be assigned to exactly one field and one activator on the passenger lift.
- one or more radio control units is assigned to one or more passenger lift systems for switching the access control.
- the system may therefore comprise individual passenger lifts or several passenger lifts as well as individual or multiple control units.
- the radio control unit (s) associated with one or more passenger lift systems are factory-tuned to the circuit of the passenger lift system or the passenger lift systems, in particular with regard to the radio frequency and / or the switching signal identity or Encryption.
- a "closed system” is provided, which, once it has been agreed, assigns a certain number of persons with radio control units precisely to a certain number of passenger lift systems and makes these passenger lift systems accessible to those persons.
- the radio control unit (s) associated with one or more passenger lift systems would be programmable or otherwise variably tunable to the circuitry of the passenger lift system or passenger lift systems, in particular radio frequency and / or switching signal identity or encryption. It is possible to make the radio control units by local data transmission, in particular via the Internet, programmable and tunable to the circuit of the passenger lift system or the passenger lift systems. Specifically, this has an advantageous effect if an activation in the access authorization for a particular group of persons equipped with programmable radio control units is to take place, in particular for passenger lift systems in public buildings.
- persons or groups of people who may identify themselves to the authorities as movement-impaired could download an activation code over the Internet for a particular public building, transfer it to their radio control unit via an interface (eg USB), and then when entering the building by approach the respective lift systems unlock.
- an interface eg USB
- the stairlift system shown in the drawing comprises the chair 20, which comprises a backrest 23, a seat 25, a vertical plate 28 and a tread 22. Furthermore, two armrests 24 with arm or hand rest 26 are arranged on the seat.
- the chair travels on a rail system with two rails 32 and 34 carried by supports 30; They are usually attached to the edge of the stairs.
- a drive is arranged on the chair below the seat 25, which is not visible in the drawing itself and has been indicated by dashed lines only at 18.
- the user sitting on the seat 25 will be able to operate the drive 18 by means of a joystick 16 and thus be able to ride the chair 20 on the rails 32, 34.
- the joystick 16 is mounted on one of the hand rests, and its connection to the drive 18 is present, but not shown separately.
- a switch 14 Shown is in the palm rest and below the joystick 16, a switch 14, which can turn the joystick on or off, so controls the effectiveness of the operation of the joystick.
- This switch 14 is, as indicated by a dashed line 12, connected to a field generator activator unit 10, which is also hidden behind the plate 28 and therefore has been drawn by dashed lines.
- the field generator activator unit 10 can control the switch 14 via the line 12 and thus switch the joystick 16 to be functional or inoperative.
- the arrangement of the unit 10 depends on the particular embodiment of the passenger lift system and can advantageously be carried out so that the power supply of the drive 18 can be used with.
- its own, in particular rechargeable supply of energy for example by a battery or a rechargeable battery can be used.
- the Components that are connected by the line 12, so in the present case, the switch 14 and the unit 10 are not located on mutually movable parts to make a signal transmission easy.
- the other case can be solved, for example with wireless signal transmission or with the help of sliding contacts.
- the activator 10 should be integrated into the environment of the transport unit or person carrying unit in such a way that, on the one hand, it is safely accommodated and, on the other hand, it can be easily wired.
- the seat could be 20 (free) switched if it is designed as a swivel seat and allows only in a certain rotational position, the movement of the stair lift.
- the combined field generator activator unit 10 In its capacity as a field generator, the combined field generator activator unit 10 generates a radio field 50 which surrounds the seat 20 and has a limited effective range. In the present case, the effective range should be about 2m - 3m.
- the radio field 50 includes a tuned thereto control unit 70, which is shown within the field 50, while the same unit for the later explanation of an additional function again outside the field than 71 'is drawn.
- the design of the radio activation is now such that in the event that the unit 70 moves into the effective field 50, the presence of the panel 50 is detected in the unit.
- the technique to be used for this purpose is known and will not be described here.
- the unit 70 determines that it is in the field 50, a further action is initiated.
- the interaction of the panel 50 with the unit 70 is shown by the arrow 57.
- unit 70 will generate signal 60 and communicate with field generator activator unit 10 (arrow 71). This will be a Release situation triggered in which the activator 10 controls the switch 16 and thus allows the control of the stair lift by means of the joystick 16.
- the radio control unit 70 which can be configured, for example, as a key fob or belt support unit leaves the field 50 again, the activator 10 will switch the switch 14 again so that the joystick 16 is disabled and the control of the stair lift not more is possible.
- the route via an active detection of a field presence in the radio control unit is not necessarily necessary for the present invention. It would also be possible to use the radio control unit as a passive, e.g. excitable element whose presence can be detected by the field generator activator unit when it enters the excitation field. This is similar to the use of RFID transponders in store / theft prevention systems.
- the radio control unit 70 can itself be used as an active control unit when implementing a preferred embodiment of the invention.
- the corresponding radio control unit 70 ' is shown at the top of the drawing and includes an auxiliary switch 72 which can transmit a remote control signal.
- This remote control signal would act on the activator 10, releasing the joystick 16 with the switch 14.
- Such a release may be switched, for example, over a period of time so that an outsider (eg, a doorman in a public building) may temporarily release the use of the stairlift for a person who does not have his own radio control unit 70.
Abstract
Description
Die vorliegende Erfindung betrifft ein Personenliftsystem, das durch eine Zugriffskontrolle vor unbefugter Benutzung geschützt ist. Im Allgemeinen und gemäß dem Stand der Technik weisen solche Personenliftsysteme eine Personen-Trageeinheit und einen Antrieb für diese Personen-Trageeinheit auf, wobei dem Antrieb eine Zugriffskontrolle zugeordnet, insbesondere vor-, zu- oder nachgeschaltet ist.The present invention relates to a passenger lift system which is protected by an access control against unauthorized use. In general and in accordance with the state of the art, such passenger lift systems have a person-carrying unit and a drive for this person-carrying unit, wherein the drive is assigned an access control, in particular upstream, upstream or downstream.
Ein Beispiel für ein solches Personenliftsystem ist ein Treppenlift. Herkömmliche Treppenlifte weisen als Zugriffskontrolle oftmals ein Schloss auf, welches im abgeschlossenen Zustand die Bedienung des die Fahrt steuernden Elements (beispielsweise eines Joysticks) des Treppenlifts verhindert wird. Mit einem Schlüssel können berechtigte Personen das Schloss öffnen und dann den Treppenlift benutzen und bedienen.An example of such a passenger lift system is a stairlift. Conventional stairlifts often have a lock as access control, which in the closed state prevents the operation of the travel-controlling element (for example a joystick) of the stairlift. With a key, authorized persons can open the lock and then use and operate the stairlift.
Nachteiligerweise sind gerade Personen, die auf die Hilfe von Personenliftsystemen angewiesen sind, auch oft mit Schwierigkeiten konfrontiert, wenn sie derartige Schlösser aufschließen sollen. Die Zugriffs-Freigabe wird dadurch erschwert und in manchen Fällen, gerade wenn ältere Menschen oder behinderte Menschen Schwierigkeiten beim Einbringen des Schlüssels in das Schloss haben, kann die Benutzung nahezu oder gänzlich unmöglich werden.Disadvantageously, even persons who rely on the assistance of passenger lift systems are also often faced with difficulties if they are to unlock such locks. Access clearance is made more difficult and in some cases, especially when elderly or disabled people have difficulty inserting the key into the lock, use can become near or completely impossible.
Die vorliegende Erfindung hat es sich zur Aufgabe gemacht, ein Personenliftsystem so weiter zu entwickeln, dass die Nachteile des Standes der Technik überwunden werden. Insbesondere soll ein umkomplizierter Zugriff auf die Freigabe eines mit Zugriffskontrolle versehenen Personenliftsystems ermöglicht werden.The present invention has set itself the task of developing a passenger lift system so that the disadvantages of the prior art are overcome. In particular, a complicate access to the release of a provided with access control passenger lift system should be made possible.
Diese Aufgabe wird erfindungsgemäß durch ein Personenliftsystem gemäß dem Anspruch 1 gelöst. Die Unteransprüche definieren bevorzugte Ausführungsformen der Erfindung.This object is achieved by a passenger lift system according to claim 1. The subclaims define preferred embodiments of the invention.
Das erfindungsgemäße Personenliftsystem weist einen Funkfeldgenerator auf, der im Bereich der Personen-Trageeinheit ein räumlich wirkungsbegrenztes Streufeld erzeugt, eine Funk-Steuereinheit, die in das Streufeld einbringbar ist, und einen Aktivator, der in Reaktion auf ein wirksames Einbringen der Steuereinheit in das Streufeld die Zugriffskontrolle schaltet, insbesondere antriebsbereit schaltet.The person lift system according to the invention has a radio field generator which generates a spatially limited effect field in the area of the person carrying unit, a radio control unit which can be introduced into the stray field, and an activator which in response to an effective introduction of the control unit in the stray field Access control switches, in particular drives ready switched.
Mit anderen Worten schafft die vorliegende Erfindung eine auf einem Funksystem basierende Zugangskontrolle bzw. Zugangsberechtigungskontrolle für einen Personenlift, die berührungslos arbeitet und den Aktivator zur Schaltung der Zugriffskontrolle fernsteuert. Man könnte auch sagen, dass die Erfindung eine Annäherungs-Freischaltung für ein Personenliftsystem bereitstellt, die insbesondere keine mechanische Betätigung mehr erfordert.In other words, the present invention provides a radio system-based access control for a passenger lift that operates without contact and remotely controls the activator for switching access control. It could also be said that the invention provides an approach release for a passenger lift system which in particular no longer requires any mechanical actuation.
Der Vorteil liegt dabei insbesondere darin, dass auch Menschen mit Bewegungsbehinderungen oder motorischen Behinderungen, für die solche Personenliftsysteme oftmals speziell vorgesehen sind, ohne Weiteres die Zugriffskontrolle eines solchen Liftsystems überwinden, also das Liftsystem zur Benutzung freischalten können. Dabei müssen sie nichts anderes tun als die Funk-Steuereinheit bei sich zu tragen, da sie bei der Annäherung an das Personenliftsystem bzw. an den Aktivator und den Funkfeldgenerator automatisch die Freischaltung des Antriebs bzw. der Zugriffskontrolle bewirken können. Eine Person mit Zugangsberechtigung muss sich also einfach in oder auf die Personentrageeinheit begeben und kann unmittelbar mit dem Transport beginnen, während unberechtigte Personen keinen Gebrauch von dem Personenliftsystem machen können. Dies alles geschieht in gänzlich automatisierter Art und Weise und ohne besondere Anforderungen an die Handhabungsfertigkeiten des Benutzers.The advantage lies in the fact that even people with disabilities or motor disabilities, for which such Passenger lift systems are often specifically provided, easily overcome the access control of such a lift system, so can unlock the lift system for use. They have nothing to do but carry the radio control unit with them, since they can automatically cause the activation of the drive or the access control when approaching the passenger lift system or to the activator and the radio field generator. A person with access authorization must therefore simply go into or on the person carrying unit and can start transport immediately, while unauthorized persons can not make use of the passenger lift system. All this happens in a completely automated manner and without any special demands on the handling skills of the user.
Ein Personenliftsystem gemäß der vorliegenden Erfindung kann eines der folgenden Systeme sein:
- ein Treppenliftsystem mit einem Sitz oder Stuhl als Personen-Trageeinheit und einem dem Sitz oder Stuhl zugeordneten Laufschienenantrieb,
- ein Plattformliftsystem mit einer betretbaren oder befahrbaren Plattform,
- ein Rampenliftsystem,
- ein Kabinenliftsystem.
- a stairlift system with a seat or chair as a person-carrying unit and a runner drive associated with the seat or chair,
- a platform lift system with an accessible or navigable platform,
- a ramp lift system,
- a cabin lift system.
Die obige Liste gibt Beispiele für erfindungsgemäße Systeme an, ist jedoch nicht erschöpfend. So ist es beispielsweise nicht unbedingt notwendig, dass durch das Personenliftsystem gemäß der vorliegenden Erfindung ein Höhenunterschied überwunden wird, vielmehr kann der Transport der Personen auch zu einem wesentlichen Teil oder lediglich horizontal erfolgen. In vielen Fällen dürfte sich der Einsatz von erfindungsgemäßen Personenliftsystemen besonders für bewegungsbehinderte Menschen lohnen, was sich natürlich speziell vorteilhaft dann auswirkt, wenn solchen Personen dabei geholfen wird, Höhenunterschiede zu überwinden. Horizontale Anordnungen, wie z.B. Transportbänder, liegen aber grundsätzlich auch im allgemeinen Umfang der vorliegenden Erfindung, deren Einsatzgebiet sich auch dadurch charakterisieren lässt, dass die Personenbeförderung immer auf demselben Weg, also auf einer vorgegebenen, bestimmten Transportstrecke erfolgt. Ein Personenliftsystem gemäß der vorliegenden Erfindung ist deshalb auch so klassifiziert, dass es in seiner Gesamtanordnung stationär bzw. fest installiert ist und nur einen Transport innerhalb dieser Gesamtanordnung ermöglicht, speziell einen Kurzstreckentransport (über Wege von z. B. etwa 1m - 15m, bei längeren Liftsystemen oder Bändern auch bis 100m oder in dieser Größenordnung).The above list gives examples of systems according to the invention, but is not exhaustive. Thus, for example, it is not absolutely necessary that a height difference be overcome by the passenger lift system according to the present invention, but the transport of the persons can also take place to a substantial extent or only horizontally. In many cases, the use of personal lift systems according to the invention should be particularly worthwhile for people with physical disabilities, which of course has a particularly advantageous effect if such persons are helped to overcome height differences. Horizontal arrangements, such as e.g. Conveyor belts, but are basically also in the general scope of the present invention, the field of application can also be characterized by the fact that the passenger always takes place in the same way, ie on a given, specific transport route. A passenger lift system in accordance with the present invention is therefore also classified as being stationary in its overall configuration and allowing only transport within this overall arrangement, especially short haul transport (over distances of, for example, about 1m-15m, for longer periods) Lift systems or belts also up to 100m or on this scale).
Der Antrieb eines erfindungsgemäßen Personenliftsystems kann ein Handantrieb (z.B. ein Kurbelantrieb) oder ein kraftunterstützter Antrieb sein, insbesondere ein elektrischer, ein mechanischer, ein hydraulischer oder ein pneumatischer Antrieb oder eine Mischform dieser Antriebe. Dabei ist es möglich, dass an der Personentrageeinheit angeordnete Antriebselemente als passives oder aktives Antriebselement ausgestaltet werden. Ein Beispiel für ein passives Antriebselement wäre eine Klaue an einer Personentrageeinrichtung, die sich in eine extern angetriebene Laufkette oder ein Laufband einklinken oder einrasten kann. Ein Beispiel für ein aktives Antriebselement wäre ein an der Personentrageeinheit angebrachter Motor mit einem Vortriebselement, beispielsweise einer Antriebsrolle und eventuell einem dazwischen geschalteten Getriebe.The drive of a passenger lift system according to the invention may be a manual drive (eg a crank drive) or a power-assisted drive, in particular an electrical, a mechanical, a hydraulic or a pneumatic drive or a hybrid form of these drives. It is possible that at the Personentrageeinheit arranged drive elements are designed as a passive or active drive element. An example of a passive drive element would be a claw on a person carrying device that can engage or snap into an externally driven track or treadmill. An example of an active drive element would be a mounted on the person carrying unit engine with a propulsion element, such as a drive roller and possibly a gearbox connected therebetween.
Der Aktivator kann, um die Zugriffskontrolle antriebsbereit zu schalten, direkt oder indirekt eine Funktionssperre des Personenliftsystems betätigen, insbesondere
- am Antrieb selbst, und/oder
- an der Energieversorgung des Antriebs, und/oder
- an einem Bedienelement (16) zur Fortbewegungssteuerung, z.B. einem Taster oder einem Joystick.
- on the drive itself, and / or
- at the power supply of the drive, and / or
- on a control element (16) for locomotion control, such as a button or a joystick.
Natürlich kann, beispielsweise bei externen Antriebssystemen, auch die gesamte Energieversorgung geschaltet, also eingeschaltet oder ausgeschaltet, werden. Im Grunde eignet sich jedes schaltbare Element oder stellbare Element für die Zugriffskontrolle, das eine Bewegung oder Bedienung des Personenliftsystems möglich oder unmöglich machen kann.Of course, for example, in external drive systems, the entire power supply switched, so turned on or off, are. Basically, any switchable element or adjustable element is suitable for access control, which may make movement or operation of the passenger lift system impossible or impossible.
Der Funkfeldgenerator und der Aktivator können ein einziges Bauteil oder in einem Bauteil vereinigt sein. Es ist natürlich auch möglich, sie als getrennte Einheiten bereitzustellen und in einem einzigen oder mehreren Gehäusen unterzubringen. Die gemeinsame oder benachbarte Unterbringung spart Signalwege ein, während durch eine Trennung möglicherweise eine Platzersparnis erzielt werden kann oder sich eine bessere Nutzung freier Räume ergibt.The radio field generator and the activator can be a single component or combined in one component. Of course, it is also possible to provide them as separate units and accommodate them in a single or multiple housings. The common or adjacent housing saves signal paths, while a separation may possibly result in a space saving or a better utilization of free spaces.
Das Funkgeneratorfeld kann ein Streufeld mit einem wirksamen Abstand vom Aktivator im Bereich von 0,25 m bis 5 m sein. Speziell vorteilhafte Bereiche reichen von 1 m bis 3 m oder von 1 m bis 2m. Auch Bereiche von 0 bis 1 m können vorteilhaft sein. Die Auswahl wird je nach Anwendungsfall und zu erreichenden Vorteilen getroffen. Möchte man beispielsweise verhindern, dass die Freischaltung schon erfolgt, wenn sich die eine berechtigte Person mit einer Sendereinheit in einer weiteren Umgebung befindet, kann man den Wirksamkeitsradius beispielsweise auf bis zu 1m oder bis zu 2m einschränken. Wenn sichergestellt ist, dass der Benutzer die Funk-Steuereinheit immer am Körper und möglicherweise auch noch immer an derselben Stelle (z.B. Gürtelhalterung) trägt, lassen sich auch recht kleine wirksame Felder realisieren, beispielsweise mit einem Abstand vom Aktivator von bis zu 0,25m oder 0,5m. Dadurch könnte Energie eingespart werden, die beim Aufbau des Feldes benötigt wird.The radio generator field may be a stray field with an effective distance from the activator in the range of 0.25 m to 5 m. Especially advantageous ranges are from 1 m to 3 m or from 1 m to 2 m. Also ranges from 0 to 1 m can be advantageous. The choice depends on the application and the benefits to be achieved met. If you want to prevent, for example, that the activation already takes place when the one authorized person with a transmitter unit in a wider environment, you can limit the effectiveness radius, for example, up to 1m or up to 2m. If it is ensured that the user always carries the radio control unit on the body and possibly also in the same place (eg belt holder), also very small effective fields can be realized, for example with a distance from the activator of up to 0.25 m or 0.5m. This could save energy needed to build the field.
Ein erfindungsgemäßes Personenliftsystem kann so ausgestaltet werden, dass der Funkfeldgenerator, die Funk-Steuereinheit und/oder der Aktivator mit Funkeinheiten ausgestaltet sind, die eine Kommunikation bzw. Wechselwirkung auf
- einem RFID-Frequenzband, und/oder
- einem Bluetooth-Frequenzband, und/oder
- dem kHz-Frequenzband (z. B. 125 kHz), und/oder
- dem MHz-Frequenzband (z. B. 433 oder 866 MHz) und/oder
- dem GHz-Frequenzband (z. B. 2,4 GHz) ermöglichen.
- an RFID frequency band, and / or
- a Bluetooth frequency band, and / or
- the kHz frequency band (eg 125 kHz), and / or
- the MHz frequency band (eg 433 or 866 MHz) and / or
- the GHz frequency band (eg 2.4 GHz).
Grundsätzlich eignen sich natürlich alle verfügbaren und erfahrungsgemäß für solche kleinen Entfernungen wirksamen Frequenzbänder.In principle, of course, all available and experience, effective for such small distances frequency bands are suitable.
Wenn, wie oben angedeutet, eine RFID-Technik verwendet wird, lassen sich die bekannten RFID-Transponder und Felderzeuger einsetzen, wie sie beispielsweise aus Diebstahlverhinderungssystemen bei Kaufhäusern bekannt sind.If, as indicated above, an RFID technology is used, the known RFID transponders and field generators can be used, as are known, for example, from theft prevention systems in department stores.
Um die Zugriffskontrolle sicher zu gestalten, ist es möglich, die Schaltsignale mit einem Hochsicherheitscode zu verschlüsseln, insbesondere mit einer 128Bit bis 1024Bit Verschlüsselung.To make the access control secure, it is possible to encrypt the switching signals with a high security code, in particular with a 128Bit to 1024Bit encryption.
Bei einer Ausführungsform der vorliegenden Erfindung weist die Funk-Steuereinheit mindestens einen Zusatzschalter zur Fernbedienung bzw. Fernauslösung der durch die Zugriffskontrolle unterstützten Zugangsberechtigungskontrolle auf, wobei der Zusatzschalter zum Absenden eines Bedienungssignals durch einen Sender an der Steuereinheit ausgebildet ist. So lässt sich der automatischen Annäherungs-Freigabe noch eine manuelle und separate Freigabe hinzufügen, die den Funktionsbereich der vorliegenden Erfindung noch erweitert. Beispielsweise können mit einer solchen Kombination andere Personen, sozusagen von außen, die Freischaltung des Personenliftsystems bewirken. Die Reichweite des Senders an der Steuereinheit kann dabei vorteilhafterweise größer sein als die wirksame Abmessung des Streufeldes, insbesondere mindestens das 1,5-fache, das 2-fache oder das 3-fache dieser Abmessung betragen, speziell in einem Bereich von 3 bis 20m und sogar bis zu 100m (z. B. für Transportbänder) liegen.In one embodiment of the present invention, the radio control unit has at least one additional switch for remote control of the access control supported by the access control, wherein the auxiliary switch for sending an operation signal is formed by a transmitter on the control unit. Thus, the automatic proximity release can still add a manual and separate release, which extends the scope of the present invention even more. For example, with such a combination other people, so to speak from the outside, cause the activation of the passenger lift system. The range of the transmitter on the control unit can advantageously be greater than the effective dimension of the stray field, in particular at least 1.5 times, be 2 times or 3 times this dimension, especially in a range of 3 to 20m and even up to 100m (eg for conveyor belts).
Gemäß einer Ausführungsvariante des erfindungsgemäßen Personenliftsystems bewirken die Schaltsignale für die Zugriffskontrolle gezielte, einzelne Zugangsberechtigungen. Für den Heimgebrauch kann also genau eine Funk-Steuereinheit mit einem Auslöseprotokoll genau einem Feld und einem Aktivator am Personenlift zugeordnet sein.According to one embodiment variant of the passenger lift system according to the invention, the switching signals for the access control bring about targeted, individual access authorizations. For home use, therefore, exactly one radio control unit with a triggering protocol can be assigned to exactly one field and one activator on the passenger lift.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung bezieht sich diese noch auf ein Zugangsberechtigungs-Kontrollsystem, das die Berechtigung zur Benutzung mindestens eines Personenliftsystems regelt, wie es oben in verschiedenen Ausführungsformen beschrieben worden ist. Dabei ist oder sind eine oder mehrere Funk-Steuereinheiten einem oder mehreren Personenliftsystemen zur Schaltung der Zugriffskontrolle zugeordnet. Das System kann also einzelne Personenlifte oder mehrere Personenlifte sowie einzelne oder mehrere Steuereinheiten umfassen.According to another aspect of the present invention, this still relates to an access authorization control system that regulates the authorization to use at least one passenger lift system, as described above in various embodiments. In this case, one or more radio control units is assigned to one or more passenger lift systems for switching the access control. The system may therefore comprise individual passenger lifts or several passenger lifts as well as individual or multiple control units.
Bei einer Ausführungsform sind die einem oder mehreren Personenliftsystemen zugeordneten Funk-Steuereinheit(en) werksseitig unveränderbar auf die Schaltung des Personenliftsystems bzw. der Personenliftsysteme abgestimmt, insbesondere hinsichtlich der Funkfrequenz und/oder der Schaltsignalidentität bzw. - Verschlüsselung. Hier wird also sozusagen ein "geschlossenes System" bereitgestellt, das, wenn es einmal abgestimmt ist, eine bestimmte Anzahl von Personen mit Funk-Steuereinheiten genau einer bestimmten Anzahl von Personenliftsystemen zuordnet und diese Personenliftsysteme für diejenigen Personen zugänglich macht.In one embodiment, the radio control unit (s) associated with one or more passenger lift systems are factory-tuned to the circuit of the passenger lift system or the passenger lift systems, in particular with regard to the radio frequency and / or the switching signal identity or Encryption. Here, so to speak, a "closed system" is provided, which, once it has been agreed, assigns a certain number of persons with radio control units precisely to a certain number of passenger lift systems and makes these passenger lift systems accessible to those persons.
Bei einem "offenen" System wären die einem oder mehreren Personenliftsystemen zugeordneten Funk-Steuereinheit(en) programmierbar oder anderweitig veränderbar auf die Schaltung des Personenliftsystems bzw. der Personenliftsysteme abstimmbar, insbesondere hinsichtlich der Funkfrequenz und/oder der Schaltsignalidentität bzw. -verschlüsselung. Dabei ist es möglich, die Funk-Steuereinheiten durch überörtliche Datenübertragung, insbesondere über das Internet, programmierbar und auf die Schaltung des Personenliftsystems bzw. der Personenliftsysteme abstimmbar zu machen. Speziell wirkt sich dies dann vorteilhaft aus, wenn eine Freischaltung in der Zugangsberechtigung für einen bestimmten, mit programmierbaren Funk-Steuereinheiten ausgestatteten Personenkreis erfolgen soll, im Besonderen für Personenliftsysteme in öffentlichen Gebäuden. Beispielsweise könnten sich Personen oder Personengruppen, die sich bei Behörden als Bewegungsbehindert identifizieren können (beispielsweise durch eine Sicherheitsabfrage im Internet) einen Freischaltcode über das Internet für ein bestimmtes öffentliches Gebäude herunterladen, über eine Schnittstelle (z.B. USB) auf ihre Funk-Steuereinheit übertragen, und dann beim Betreten des Gebäudes durch Annäherung die jeweiligen Personenliftsysteme freischalten.In an "open" system, the radio control unit (s) associated with one or more passenger lift systems would be programmable or otherwise variably tunable to the circuitry of the passenger lift system or passenger lift systems, in particular radio frequency and / or switching signal identity or encryption. It is possible to make the radio control units by local data transmission, in particular via the Internet, programmable and tunable to the circuit of the passenger lift system or the passenger lift systems. Specifically, this has an advantageous effect if an activation in the access authorization for a particular group of persons equipped with programmable radio control units is to take place, in particular for passenger lift systems in public buildings. For example, persons or groups of people who may identify themselves to the authorities as movement-impaired (for example, through a security query on the Internet) could download an activation code over the Internet for a particular public building, transfer it to their radio control unit via an interface (eg USB), and then when entering the building by approach the respective lift systems unlock.
Die Erfindung wird im Weiteren anhand einer Ausführungsform und unter Bezugnahme auf die beiliegende Zeichnung näher erläutert. Sie kann alle hierin aufgeführten Merkmale einzeln sowie in jedweder sinnvollen Kombination umfassen.The invention will be explained in more detail below with reference to an embodiment and with reference to the accompanying drawings. It may include all of the features listed herein individually and in any convenient combination.
Die einzige beiliegende Zeichnung zeigt ein Treppenliftsystem, das als Ausführungsform eines erfindungsgemäßen Personenliftsystems mit einer erfindungsgemäßen Zusatzberechtigungs-Kontrolle ausgestattet ist.The sole accompanying drawing shows a stairlift system, which is equipped as an embodiment of a passenger lift system according to the invention with an additional entitlement control according to the invention.
Das in der Zeichnung dargestellte Treppenliftsystem weist den Stuhl 20 auf, der eine Rückenlehne 23, eine Sitzfläche 25, eine senkrechte Platte 28 und eine Trittfläche 22 umfasst. Ferner sind an dem Sitz zwei Armlehnen 24 mit Arm- oder Handauflagen 26 angeordnet.The stairlift system shown in the drawing comprises the chair 20, which comprises a
Der Stuhl fährt auf einem Schienensystem mit zwei Schienen 32 und 34, die durch Stützen 30 getragen werden; sie sind meist im Treppenrandbereich befestigt.The chair travels on a rail system with two
Um den Stuhl auf den Laufschienen 32, 34 zu bewegen, ist an dem Stuhl unterhalb der Sitzfläche 25 ein Antrieb angeordnet, der in der Zeichnung selbst nicht sichtbar und nur beim Bezugszeichen 18 gestrichelt angedeutet worden ist.To move the chair on the
Im regulären, freigeschalteten Betrieb, wird der auf der Sitzfläche 25 sitzende Benutzer mit Hilfe eines Joysticks 16 den Antrieb 18 bedienen können und so dazu in der Lage sein, mit dem Stuhl 20 auf den Schienen 32, 34 zu fahren. Der Joystick 16 ist auf einer der Handauflagen angebracht, und seine Verbindung mit dem Antrieb 18 ist zwar vorhanden, aber nicht separat dargestellt.In regular, unlocked operation, the user sitting on the
Dargestellt ist aber in der Handauflage und unterhalb des Joysticks 16 ein Schalter 14, der den Joystick ein- oder ausschalten kann, also die Wirksamkeit der Bedienung des Joysticks kontrolliert. Dieser Schalter 14 ist, wie mit einer gestrichelten Linie 12 angedeutet ist, mit einer Feldgenerator-Aktivator-Einheit 10 verbunden, welche ebenfalls versteckt hinter der Platte 28 angeordnet und deshalb gestrichelt gezeichnet worden ist. Je nach Freigabesituation bzw. Zugriffsberechtigung kann die Feldgenerator-Aktivator-Einheit 10 über die Leitung 12 den Schalter 14 steuern und damit den Joystick 16 funktionsfähig oder nicht funktionsfähig schalten.Shown is in the palm rest and below the
Die Anordnung für die Einheit 10 hängt von der jeweiligen Ausgestaltung des Personenliftsystems ab und kann vorteilhafterweise so erfolgen, dass die Energieversorgung des Antrieb 18 mit verwendet werden kann. Natürlich kann auch eine eigene, insbesondere aufladbare Versorgung mit Energie, beispielsweise durch eine Batterie oder einen Akku verwendet werden. Ferner ist es von Vorteil, wenn die Bauteile, die durch die Leitung 12 verbunden sind, also im vorliegenden Fall der Schalter 14 und die Einheit 10, sich nicht an gegenseitig beweglichen Teilen befinden, um eine Signalübertragung einfach zu gestalten. Natürlich kann aber auch der andere Fall gelöst werden, beispielsweise mit drahtloser Signalübertragung oder mit Hilfe von Schleifkontakten.The arrangement of the
Allgemein gilt, dass der Aktivator 10 so in das Umfeld der Transporteinheit bzw. Personen-Trageeinheit integriert werden sollte, dass er einerseits sicher untergebracht und andererseits gut verkabelbar ist.In general, the
Es ist auch nicht unbedingt nötig, den Joystick 16 zu schalten. Beispielsweise könnte der Sitz 20 (frei-)geschaltet werden, wenn er als Drehsitz ausgestaltet ist und nur in einer bestimmten Drehstellung die Fortbewegung des Treppenlifts ermöglicht.It is also not necessary to switch the
In ihrer Eigenschaft als Feldgenerator erzeugt die kombinierte Feldgenerator-Aktivator-Einheit 10 ein Funkfeld 50, das den Sitz 20 umgibt und einen begrenzten Wirkungsbereich hat. Im vorliegenden Fall dürfte der Wirkungsbereich etwa 2m - 3m betragen. Zu diesem Funkfeld 50 gehört eine hierauf abgestimmte Steuereinheit 70, die innerhalb des Feldes 50 dargestellt ist, während die gleiche Einheit für die spätere Erläuterung einer Zusatzfunktion nochmal außerhalb des Feldes als 71' gezeichnet ist.In its capacity as a field generator, the combined field
Die Ausgestaltung der Funkfreischaltung ist nun eine solche, dass für den Fall, dass sich die Einheit 70 in das wirksame Feld 50 begibt, in der Einheit die Anwesenheit des Feldes 50 festgestellt wird. Die hierzu zu verwendende Technik ist bekannt und wird hier nicht näher beschrieben. Wenn die Einheit 70 also feststellt, dass sie sich in dem Feld 50 befindet, wird ein weiteres Vorgehen ausgelöst. Die Wechselwirkung des Feldes 50 mit der Einheit 70 ist durch den Pfeil 57 dargestellt.The design of the radio activation is now such that in the event that the unit 70 moves into the
Nun tritt eine weitere Wechselwirkung bzw. Kommunikation in Kraft. Wie durch den Pfeil 76 dargestellt ist, wird die Einheit 70 ein Signal 60 erzeugen und mit der Feldgenerator-Aktivator-Einheit 10 in Verbindung treten (Pfeil 71). Dadurch wird eine Freigabesituation ausgelöst, bei welcher der Aktivator 10 den Schalter 16 steuert und somit die Steuerung des Treppenlifts mittels des Joysticks 16 ermöglicht.Now another interaction or communication comes into force. As indicated by arrow 76, unit 70 will generate signal 60 and communicate with field generator activator unit 10 (arrow 71). This will be a Release situation triggered in which the
Wenn die Funk-Steuereinheit 70, die beispielsweise als Schlüsselanhänger oder Gürtel-Trageeinheit ausgestaltet werden kann, das Feld 50 wieder verlässt, wird der Aktivator 10 den Schalter 14 wieder so schalten, dass der Joystick 16 außer Funktion gesetzt wird und die Steuerung des Treppenlifts nicht mehr möglich ist.If the radio control unit 70, which can be configured, for example, as a key fob or belt support unit leaves the
Es soll hier ausdrücklich erwähnt werden, dass der Weg über eine aktive Feststellung einer Feldpräsenz in der Funk-Steuereinheit nicht unbedingt für die vorliegende Erfindung notwendig ist. Es wäre ebenso möglich, die Funk-Steuereinheit als ein passives, z.B. erregbares Element auszugestalten, dessen Präsenz durch die Feldgenerator-Aktivator-Einheit festgestellt werden kann, wenn es in das Anregungsfeld eintritt. Dies ist mit der Verwendung von RFID-Transpondern bei Warenhaus/Diebstahl-Verhinderungssystemen vergleichbar.It should be expressly mentioned here that the route via an active detection of a field presence in the radio control unit is not necessarily necessary for the present invention. It would also be possible to use the radio control unit as a passive, e.g. excitable element whose presence can be detected by the field generator activator unit when it enters the excitation field. This is similar to the use of RFID transponders in store / theft prevention systems.
Schließlich wird noch darauf hingewiesen, dass die Funk-Steuereinheit 70 auch selbst als aktive Steuereinheit verwendet werden kann, wenn eine bevorzugte Ausführungsform der Erfindung umgesetzt wird. Die entsprechende Funk-Steuereinheit 70' ist oben in der Zeichnung dargestellt, und sie umfasst einen Zusatzschalter 72, der ein Fernsteuerungssignal aussenden kann. Dieses Fernsteuerungssignal würde so auf den Aktivator 10 wirken, das er mit dem Schalter 14 den Joystick 16 freigibt. Eine solche Freigabe kann beispielsweise über einen gewissen Zeitraum geschaltet werden, so dass ein Außenstehender (beispielsweise ein Portier in einem öffentlichen Gebäude) die Benutzung des Treppenlifts vorübergehend für eine Person freigeben kann, die keine eigene Funk-Steuereinheit 70 besitzt.Finally, it should be noted that the radio control unit 70 can itself be used as an active control unit when implementing a preferred embodiment of the invention. The corresponding radio control unit 70 'is shown at the top of the drawing and includes an
