Description

KommunikationsSystemCommunication system
Die Erfindung betrifft ein Kommunikationssystem mit wenigstens einer mobilen Kommunikationseinrichtung mit den im Oberbegriff des Anspruchs 1 genannten Merkmalen .The invention relates to a communication system with at least one mobile communication device with the features mentioned in the preamble of claim 1.
Stand der TechnikState of the art
Ortsbewegliche Kommunikationssysteme der gattungsgemäßen Art sind bekannt. Diese weisen wenigstens eine mobile Kommunikationseinrichtung auf, mittels der eine Aktion von mit der Kommunikationseinrichtung kommunizierenden weiteren Einrichtungen auslösbar ist. So kann beispielsweise über eine Funkfernsteuerung der Kommunikationseinrichtung eine Betätigung verschiedener Geräte und/oder Einrichtungen innerhalb eines Einsatzgebietes erfolgen. Typische Einsatzgebiete sind beispielsweise ein Gebäude mit mehreren Räumen, wobei innerhalb der Räume unterschiedliche Geräte mittels der Kommunikationseinrichtung betätigbar sind. Da beim Einsatz von Funkfernsteuerungen die Funkwellen die Eigenschaft haben, Begrenzungswände der einzelnen Räume und Gegenstände zu durchdringen, muß die Kommunikationseinrichtung so ausgelegt sein, daß eine Bedienung nur eines bestimmten Gerätes möglich ist, ohne daß ebenfalls mit der Kommunikations- einrichtung betätigbare Einrichtungen in anderen Räumen ebenfalls ausgelöst werden. Hierzu ist be- kannt , die Kommunikationseinrichtung mit einer entsprechenden Anzahl von Betätigungsmitteln zu versehen, um jede mögliche Steuerfunktion innerhalb des Wirkungsbereiches separat ausführen zu können oder einige Steuerfunktionen auf eine Kombination bezie- hungsweise eine zeitliche Abfolge von Betätigungsmitteln abzubilden.Portable communication systems of the generic type are known. These have at least one mobile communication device, by means of which an action can be triggered by further devices communicating with the communication device. For example, a radio remote control of the communication device can be used to actuate various devices and / or devices within an area of application. Typical areas of application are, for example, a building with several rooms, different devices being operable within the rooms by means of the communication device. Since the radio waves have the property of penetrating the boundary walls of the individual rooms and objects when using radio remote controls, the communication device must be designed in such a way that that only one particular device can be operated without devices in other rooms which can also be actuated with the communication device also being triggered. For this purpose, it is known to provide the communication device with a corresponding number of actuating means in order to be able to carry out each possible control function within the effective range separately or to map some control functions to a combination or a chronological sequence of actuating means.
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße ortsbewegliche Kommunikationssystem mit den im Anspruch 1 genannten Merkmalen bietet den Vorteil, daß in einfacher Weise eine räumlich abhängige Mehrfachbelegung von Betätigungsmitteln der Kommunikationseinrichtung möglich ist. Dadurch, daß innerhalb eines Einsatzgebietes der wenigstens einen Kommunikationseinrichtung definierten Bereichen Positionsmarken zugeordnet sind, die bei Eintritt der Kommunikationseinrichtung in den definierten Bereich der Kommunikationseinrichtung die aktuelle Position mitteilen, kann eine automatische Umschaltung der Kommunikationseinrichtung, insbesondere der Belegung des wenigstens einen Betätigungsmittels auf eine Auslösung einer Aktion einer sich in dem aktuellen definierten Bereich befindenden Einrichtung umge- schaltet werden. Somit kann mittels eines Betätigungsmittels eine Betätigung einer Vielzahl unterschiedlicher Einrichtungen erfolgen, wobei sich der Bedienkomfort der Kommunikationseinrichtung wesentlich verbessert .The portable communication system according to the invention with the features mentioned in claim 1 offers the advantage that a spatially dependent multiple assignment of actuating means of the communication device is possible in a simple manner. Due to the fact that position marks are assigned to the at least one communication device within an area of application, which indicate the current position of the communication device when the communication device enters the defined area, an automatic switchover of the communication device, in particular the assignment of the at least one actuating means, to a triggering of a Action of a facility located in the currently defined area can be switched. Thus, an actuation means can actuate a large number of different devices, the Ease of use of the communication device significantly improved.
In bevorzugter Ausgestaltung der Erfindung ist vorge- sehen, daß die Positionsmarken elektromagnetische Wellen erzeugen, die vom Kommunikationsgerät empfangen werden, wobei von zu einem Einsatzgebiet gehörenden Positionsmarken je definierten Bereich unterschiedliche elektromagnetische Wellen ausgestrahlt werden, so daß eine eindeutige Zuordnung zu einem definierten Bereich möglich ist. Über die von der Kommunikationseinrichtung empfangenen elektromagnetischen Wellen kann eine Zuordnung zu dem definierten Bereich erfolgen, und intern in der Kommunikations- einrichtung eine Umschaltung der Belegung der Betätigungsmittel erfolgen.In a preferred embodiment of the invention, it is provided that the position marks generate electromagnetic waves which are received by the communication device, different position waves belonging to an area of application emitting different electromagnetic waves for each defined area, so that an unambiguous assignment to a defined area is possible . The electromagnetic waves received by the communication device can be assigned to the defined area, and the assignment of the actuating means can be switched internally in the communication device.
In weiterer bevorzugter Ausgestaltung der Erfindung ist vorgesehen, daß die Positionsmarken durch die Kommunikationseinrichtung aktivierbar sind. Hierdurch wird sehr vorteilhaft erreicht, daß die Positionsmarken nur dann ein Positionssignal der Kommunikations- einrichtung geben, wenn diese in den, den aktivierten Positionsmarken zugeordneten, definierten Bereich eintritt. Somit befinden sich sämtliche Positionsmar- ken innerhalb des Einsatzgebietes in Bereitschaft und werden nur dann aktiviert, wenn die Kommunikationseinrichtung in ihren Bereich gelangt.In a further preferred embodiment of the invention it is provided that the position marks can be activated by the communication device. In this way it is very advantageously achieved that the position marks only give a position signal to the communication device when it enters the defined area assigned to the activated position marks. Thus, all position marks within the area of use are on standby and are only activated when the communication device reaches its area.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen. ZeichnungenFurther advantageous embodiments of the invention result from the other features mentioned in the subclaims. drawings
Die Erfindung wird nachfolgend in einem Ausführungs- beispiel anhand der zugehörigen Zeichnung, die sche- matisch ein Einsatzgebiet einer Kommunikationseinrichtung zeigt, näher erläutert.The invention is explained in more detail below in an exemplary embodiment with reference to the associated drawing, which schematically shows an area of application of a communication device.
Beschreibung des AusführungsbeispielsDescription of the embodiment
In der Figur ist ein mit 10 bezeichnetes Einsatzgebiet einer Kommunikationseinrichtung 12 gezeigt. Das Einsatzgebiet 10 umfaßt beispielsweise ein Gebäude beziehungsweise Gebäudeteil 14 mit einzelnen Räumen 16, 18, 20, 22 beziehungsweise 24. Ein Kommunika- tionsraum muß nicht identisch mit der Einteilung des Gebäudes in Zimmer sein. Ein Kommunikationsraum kann beispielsweise mehrere Zimmer umfassen. Selbstverständlich ist jede andere Konstellation des Einsatzgebietes 10 denkbar. Bei dem Ausführungsbeispiel wird davon ausgegangen, daß eine Kommunikationseinrichtung 12 dem Einsatzgebiet 10 zugeordnet ist. Selbstverständlich können in vollkommen analoger Weise auch mehrere Kommunikationseinrichtungen 12 dem Einsatzgebiet 10 zugeordnet sein.In the figure, an area of application of a communication device 12, designated 10, is shown. The area of application 10 comprises, for example, a building or part of a building 14 with individual rooms 16, 18, 20, 22 or 24. A communication room does not have to be identical to the division of the building into rooms. A communication room can include several rooms, for example. Of course, any other constellation of application area 10 is conceivable. In the exemplary embodiment, it is assumed that a communication device 12 is assigned to the application area 10. Of course, a plurality of communication devices 12 can also be assigned to the application area 10 in a completely analogous manner.
In jedem der Räume 16 bis 24 ist mindestens ein Gerät 26, 28, 30, 32 beziehungsweise 34 installiert, das mittels der Kommunikationseinrichtung 12 betätigbar ist. Hierzu besitzt die Kommunikationseinrichtung 12 beispielsweise einen Funksender, während die Geräte 26 bis 34 einen entsprechenden Funkempfänger aufweisen. Die Geräte 26 bis 34 können beispielsweise Rollädenantriebe, fernsteuerbare Geräte der Unterhaltungselektronik, Videokameras und jedes andere beliebige Gerät sein, das mittels einer Funkfernsteuerung betätigbar ist.At least one device 26, 28, 30, 32 and 34 is installed in each of the rooms 16 to 24 and can be actuated by means of the communication device 12. For this purpose, the communication device 12 has, for example, a radio transmitter, while the devices 26 to 34 have a corresponding radio receiver. The devices 26 to 34 can for example Roller shutter drives, remotely controllable consumer electronics devices, video cameras and any other device that can be operated by radio remote control.
Die Räume 16 bis 24 bilden definierte Bereiche des Einsatzgebietes 10. Jedem der Räume 16 bis 24 ist eine Positionsmarke 36, 38, 40, 42 beziehungsweise 44 zugeordnet. Die Positionsmarken 36 bis 44 besitzen eine Energiequelle beziehungsweise sind mit einer Energiequelle verbunden und umfassen Einrichtungen zum Erzeugen elektromagnetischer Signale . Die elektromagnetischen Signale können beispielsweise durch Ansteuerung einer Spule mit einer VersorgungsSpannung definierter Frequenz erfolgen. Die Positionsmarken 36 bis 44 sind so ausgelegt, daß jede der Positionsmarken 36 bis 44 unterschiedliche elektromagnetische Signale, insbesondere elektromagnetische Signale unterschiedlicher Frequenz ausstrahlen.Rooms 16 to 24 form defined areas of application area 10. Each of rooms 16 to 24 is assigned a position marker 36, 38, 40, 42 or 44. The position marks 36 to 44 have an energy source or are connected to an energy source and comprise devices for generating electromagnetic signals. The electromagnetic signals can take place, for example, by controlling a coil with a supply voltage of a defined frequency. The position marks 36 to 44 are designed such that each of the position marks 36 to 44 emit different electromagnetic signals, in particular electromagnetic signals of different frequencies.
Die Kommunikationseinrichtung 12 besitzt einen Empfänger 48 für die von den Positionsmarken 36 bis 44 ausgestrahlten elektromagnetischen Signale. Die Positionsmarken 36 bis 44 sind so ausgelegt, daß die abgestrahlten elektromagnetischen Signale nur in einem eng begrenzten räumlichen Bereich von der Empfangseinheit 48 empfangbar sind. Insbesondere sind die Positionsmarken 36 bis 44 so ausgelegt, daß ein Empfangen der elektromagnetischen Signale nur bei unmittelbarem Passieren der Positionsmarken 36 bis 44 möglich ist. Die Positionsmarken 36 bis 44 können beispielsweise im Bereich von Zugangstüren zu den Räumen 16 bis 24 angeordnet sein, so daß beim Passieren einer die Kommunikationseinrichtung 12 besitzenden Person der entsprechenden Tür die Empfangseinheit 48 die von der gerade passierten Positionsmarke 36 bis 44 gesendeten elektromagnetischen Signale empfängt . Mittels der empfangenen elektromagnetischen Signale wird ein Betätigungsmittel 50 der Kommunikationseinrichtung 12 in einer Funktionsbelegung beeinflußt.The communication device 12 has a receiver 48 for the electromagnetic signals emitted by the position marks 36 to 44. The position marks 36 to 44 are designed such that the emitted electromagnetic signals can only be received by the receiving unit 48 in a narrowly limited spatial area. In particular, the position marks 36 to 44 are designed such that reception of the electromagnetic signals is only possible when the position marks 36 to 44 are passed directly. The position marks 36 to 44 can, for example, in the area of access doors to the Rooms 16 to 24 may be arranged so that when a person possessing the communication device 12 passes the corresponding door, the receiving unit 48 receives the electromagnetic signals transmitted by the position mark 36 to 44 just passed. An actuation means 50 of the communication device 12 is influenced in a functional assignment by means of the received electromagnetic signals.
Die Funktionsbelegung des Betätigungsmittels 50 ist so ausgelegt, daß bei Betreten einer der Räume 16 bis 24 eine Betätigung des sich in diesem Raum befindenden Gerätes 26 bis 34 möglich ist. Wird beispielswei- εe die Kommunikationseinrichtung 12 in den Raum 20 bewegt, empfängt die Empfangseinheit 48 von der Positionsmarke 40 ein Signal, das die Belegung des Betätigungsmittels 50 auf eine Bedienung des Gerätes 30 einstellt. Wird nun die Kommunikationseinrichtung 12 in den Raum 18 weiterbewegt, empfängt die Empfangs - einheit 48 die elektromagnetischen Signale der Positionsmarke 38, wodurch die Funktionsbelegung des Betätigungsmittels 50 auf eine Betätigung des Gerätes 28 umgestellt wird.The functional assignment of the actuating means 50 is designed such that when one of the rooms 16 to 24 is entered, the device 26 to 34 located in this room can be actuated. If, for example, the communication device 12 is moved into the room 20, the receiving unit 48 receives a signal from the position marker 40, which sets the assignment of the actuating means 50 to an operation of the device 30. If the communication device 12 is now moved further into the room 18, the receiving unit 48 receives the electromagnetic signals of the position marker 38, as a result of which the functional assignment of the actuating means 50 is switched to actuating the device 28.
Somit ist insgesamt in einfacher Weise mittels lediglich einem Betätigungsmittels 50 eine Betätigung unterschiedlichster Geräte 26 bis 34 möglich, wobei durch die Umschaltung der Funktionsbelegung jeweils nur das gerade aktuelle Gerät, das heißt, das Gerät 26 bis 34 in dessen definierten Bereich (Räume 16 bis 24) sich die Kommunikationseinrichtung 12 gerade befindet, betätigbar ist. Selbstverständlich kann die Kommunikationseinrichtung 12 zusätzliche Betätigungsmittel aufweisen, die beispielsweise eine Betätigung aller Geräte 26 bis 34 unabhängig von der gerade aktuellen Position der Kommunikationseinrichtung 12 bewirken, oder der Betätigung weiterer Geräte dienen.It is thus possible to actuate a wide variety of devices 26 to 34 in a simple manner using only one actuating means 50, with only the current device, that is to say the device 26 to 34 in its defined area (rooms 16 to 24) being switched over by the function assignment ) the communication device 12 is straight located, can be actuated. Of course, the communication device 12 can have additional actuating means which, for example, actuate all devices 26 to 34 independently of the current position of the communication device 12, or serve to actuate further devices.
Die Empfangseinheit 48 kann beispielsweise als Sende- und Empfangseinheit 48' ausgebildet sein, so daß eine Kommunikation mit den Positionsmarken 36 bis 44 möglich ist, die eine entsprechende Empfangseinrichtung aufweisen. Die so zusammenwirkenden Positionsmarken 36 bis 44 und die Sende- und Empfangseinrichtung 48' dienen der Detektion einer Bewegung der Kommunikati- onseinrichtung 12, so daß sich sämtliche Positionsmarken 36 bis 44 in einer Ruhephase befinden und nur die Positionsmarke 36 bis 44 aktiviert wird, in deren Bereich sich gerade die Kommunikationseinrichtung 12 befindet, beziehungsweise in deren Bereich die Kommu- nikationseinrichtung 12 gerade eintritt. Hierdurch ergibt sich der Vorteil, daß ein Energieverbrauch des gesamten ortsbeweglichen Kommunikationssystems auf ein notwendiges Minimum reduziert ist.The receiving unit 48 can for example be designed as a transmitting and receiving unit 48 ', so that communication with the position marks 36 to 44 is possible, which have a corresponding receiving device. The position marks 36 to 44 interacting in this way and the transmitting and receiving device 48 'serve for the detection of a movement of the communication device 12, so that all position marks 36 to 44 are in a rest phase and only the position mark 36 to 44 is activated, in whose position Area the communication device 12 is currently located, or in the area of which the communication device 12 is currently entering. This has the advantage that an energy consumption of the entire portable communication system is reduced to a necessary minimum.
Um die Bewegung der Kommunikationseinrichtung 12 detektieren zu können, kann diese beispielsweise eine Einrichtung 52 besitzen, die bei Bewegung der Kommunikationseinrichtung 12 ein entsprechendes Signal auslöst. Die Einrichtung 52 kann beispielsweise von einer in einem Käfig sich befindenden, aus einem elektrisch leitenden Material bestehenden, Kugel gebildet sein, die durch Bewegung der Kommunikations- einrichtung 12 innerhalb des Käfigs angeordnete elektrisch voneinander isolierte Kontakte kurzschließt. Durch einen derartigen Kurzschluß kann beispielsweise die Sende- und Empfangseinrichtung 48 aktiviert er- den, die daraufhin die gerade aktuelle Positionsmarke 36 bis 44 anspricht.In order to be able to detect the movement of the communication device 12, the latter can have, for example, a device 52 which triggers a corresponding signal when the communication device 12 moves. The device 52 can be formed, for example, by a ball, which is located in a cage and is made of an electrically conductive material, and which is moved by moving the communication device 12 within the cage short-circuited electrically insulated contacts. Such a short circuit can, for example, activate the transmitting and receiving device 48, which then addresses the current position marker 36 to 44.
Die von den Positionsmarken 36 bis 44 abgestrahlten elektromagnetischen Signale können beispielsweise niederfrequente Signale, im Frequenzbereich der Funksignale der Kommunikationseinrichtung 12 liegende Signale oder hochfrequente Signale sein. Durch die niederfrequenten Signale und die sich im Frequenzbereich der Kommunikationseinrichtung 12 befindlichen elektromagnetischen Signale kann sehr vorteilhaft aufgrund deren räumlicher Begrenztheit ein exaktes Abstimmen des Betätigungsmittels 50 auf den gerade aktuellen definierten Bereich (Räume 16 bis 24) erfolgen. Mittels der hochfrequenten Signale, die eine relativ geringe Reichweite besitzen, eignen sich bevorzugterweise zur Ansteuerung der Kommunikations- einrichtung 12, da so die Überlagerung von elektromagnetischen Signalen mehrerer Positionsmarken 36 bis 44 verhindert wird. The electromagnetic signals emitted by position marks 36 to 44 can be, for example, low-frequency signals, signals in the frequency range of the radio signals of communication device 12 or high-frequency signals. Due to the low frequency signals and the electromagnetic signals located in the frequency range of the communication device 12, the actuation means 50 can be very precisely matched to the currently defined area (rooms 16 to 24) due to their spatial limitation. By means of the high-frequency signals, which have a relatively short range, are preferably suitable for controlling the communication device 12, since the superimposition of electromagnetic signals of several position marks 36 to 44 is thus prevented.
