BESCHREIBUNGDESCRIPTION
Drahtlose FernbedienungseinrichtungWireless remote control device
Drahtlose Fernbedienungseinrichtungen werden üblicherweise mit dem fernzubedienenden Gerät insoweit konstruktiv zu einer Einheit zusammengefaßt, daß lediglich der Steuersender als separate Einheit ausgeführt ist. Das hat den Vorteil, daß möglichst einfache Verbindungen zwischen den selektiven Steuersignal-Decodern des Spezialempfangsteils für die vom Steuersender ausgesandten Fernbedienungssignale und den Umschalt- und Regelorganen des fernzubedienenden Gerätes entstehen und insgesamt ein Minimalaufwand angestrebt werden kann.In this respect, wireless remote control devices are usually built into a unit with the device to be remotely controlled summarized that only the tax sender as a separate Unit is executed. This has the advantage that connections between the selective control signal decoders are as simple as possible the special receiving part for the remote control signals sent by the control transmitter and the switching and regulating devices of the device to be remotely controlled arise and overall a minimal effort can be aimed for.
Ein wesentlicher Nachteil der bekannten 'integrierten' Konzeptionen für z. B. Fernseh- oder Rundfunkgeräte mit Fernbedienungseinrichtung liegt jedoch darin, daß der durch die Fernbedienungseinrichtung bedingte Mehraufwand in jedem Fall einen erheblichen Betrag von z. B. ca. DM 200,— ausmacht, was Interessenten möglicherweise vom Kauf eines solchen Gerätes abhält. A major disadvantage of the known 'integrated' concepts for z. B. televisions or radios with remote control device is that the remote control device conditional additional effort in each case a considerable amount of z. B. approx. DM 200, - makes up what interested parties may discourage the purchase of such a device.
Die Aufgabe der Erfindung liegt darin, eine solche Konzeption für Geräte mit Fernbedienungseinrichtung anzugeben, daß der wesentliche Umfang der Fernbedienungseinrichtung einer evtl. späteren Zusatzanschaffung vorbehalten bleiben kann und das für die Fernbedienung vorbereitete Gerät auch direkt bedienbar ist.The object of the invention is to provide such a concept for devices with remote control device that the the main scope of the remote control device can be reserved for a possible later additional purchase and that The device prepared for remote control can also be operated directly.
Die Erfindung betrifft eine drahtlose Fernbedienungseinrichtung, vorzugsweise für Rundfunk- und Fernsehgeräte mit wahlweise auch direkter Bedienbarkeit, unter Verwendung eines separaten Senders zur Aussendung eines oder mehrerer Steuersignale und eines Spezialempfängers für diese Steuersignale sowie der erforderlichen Decodier- und Signalaufbereitungsanordnungen für die Einstell- und Regelfunktionen des fernzubedienenden Gerätes und liegt darin, daß der Spezialempfänger für die Steuersignale zusammen mit den Decodier- und Signalauf b er eitungs anordnungen als separates Zusatzgerät ausgeführt und über eine Steckverbindung mit dem fernzubedienenden Gerät bedarfsweise verbunden ist.The invention relates to a wireless remote control device, preferably for radio and television sets with optional also direct operability, using a separate Transmitter for sending out one or more control signals and a special receiver for these control signals as well the necessary decoding and signal processing arrangements for the setting and control functions of the device to be remotely controlled and lies in the fact that the special receiver designed as a separate additional device for the control signals together with the decoding and signal processing arrangements and via a plug connection to the device to be remotely controlled is connected as required.
Wie das Blockschaltbild Abb. 1 zeigt, ist der technische Aufwand für eine Fernbedienung, z. B. von Fernseh- oder Hi-Fi-As the block diagram in Fig. 1 shows, the technical effort for a remote control, e.g. B. from television or hi-fi

Rundfunkgeräten, relativ umfangreich. Außer dem Steuersignalsender ist ein komplizierter Zusatzempfänger erforderlich, welcher Empfang, Verstärkung, Selektion und Signalaufbereitung der verschiedenen Steuersignale bewerkstelligen muß, die für die entsprechenden am Gerät zu steuernden Funktionen erforderlich sind. Verlangt man z. B. bei einem Fernsehempfänger die direkte Anwahl von 8 Programmen sowie die Regelung von Lautstärke, Helligkeit und Farbsättigung, so benötigt man mit Einbeziehung der Ein- und Aus schalt funkt ion im Minimum 15 verschiedene Steuersignale, die störsicher zu selektieren sind· Will man, wie bisher üblich, den Aufwand im Steuersignalgeber, der im allgemeinen batteriebetrieben ist, mit Rücksicht auf Gewicht und Stromverbrauch möglichst klein halten, so erweist sich eine Ausführung mit 15 verschiedenen Sendefrequenzen günstig, die jedoch relativ eng benachbart liegen und im Empfänger entsprechenden Selektionsaufwand erfordern·Radios, relatively extensive. Except for the control signal transmitter a complicated additional receiver is required, which reception, amplification, selection and signal processing of the various control signals must accomplish that are required for the corresponding functions to be controlled on the device. If one demands z. B. in a television receiver you need the direct selection of 8 programs as well as the regulation of volume, brightness and color saturation With the inclusion of the switch-on and switch-off function, a minimum of 15 different control signals, which must be selected to be interference-free If you want, as usual, the effort in the control signal generator, which is generally battery-operated, with consideration of weight and keep power consumption as low as possible, a version with 15 different transmission frequencies proves to be favorable, which, however, are relatively close together and require corresponding selection effort in the recipient
Neben dem beträchtlichen Aufwand für Verstärkung und Selektion müssen im Spezialempfänger die Schaltspannungen für die Programmwahl und die analog zu- bzw· abnehmenden Steuergleichspannungen für die Regelfunktionen gebildet werden, die jeweils über einen langen Zeitraum zu speichern sind· Besonderen Aufwand erfordert ferner die Ein- und Ausschaltfunktion, die üblicherweise über ein Schaltrelais erfolgt und den Sicherheitsvorschriften zu entsprechen hat·In addition to the considerable effort for amplification and selection, the switching voltages for the program selection must be in the special receiver and the analog increasing or decreasing DC control voltages are formed for the control functions, each of which are to be stored over a long period of time takes place via a switching relay and must comply with the safety regulations
Bei einem Rundfunkempfänger für Hi-Fi-Übertragung ist der Aufwand noch dadurch erheblich umfangreicher, daß die Funktionen der Lautstärke-, Balance- und Klangregelung von der üblichen 'heißen' Lage im NF-Signalweg zunächst durch entsprechende Wandleranordnungen auf eine analoge Gleichspannungssteuerung umzudimensionieren sind, um diese dann auf dem Weg über die Fernbedienungsschaltsignale zu beeinflussen. Auch kommt bei Rundfunkgeräten eine Schrittschaltanordnung für die Programmwahl, wie sie bei Fernsehempfängern zur Reduzierung der Anzahl der Steuerkanäle häufig angewandt wird, praktisch nicht in Betracht, da die direkte Kanalanwahl bei stationären Rundfunkgeräten allgemein verlangt wird·In the case of a radio receiver for hi-fi transmission, the effort is even more extensive because the functions the volume, balance and tone control from the usual 'hot' position in the LF signal path through appropriate Converter arrangements are to be re-dimensioned to an analog DC voltage control, in order to then use them on the way To influence remote control switching signals. In the case of radio sets, there is also a step-by-step arrangement for program selection, as it is often used in television receivers to reduce the number of control channels, practically not into consideration, since direct channel selection is generally required for stationary radio devices
Der zuvor umrissene technische Aufwand einer Fernbedienungseinrichtung ist, wie man sieht, erheblich und verteuert ein damit ausgerüstetes Gerät bedeutend. Bei dieser Sachlage bietet allein die erfindungsgemäße Konzeption mit separat ausgeführtem Spezialempfänger eine Möglichkeit, ein für Fernbedienung vorbereitetes Gerät und den zusätzlichen Komfort der Fernbedienung durch evtl. spätere Nachrüstung ohne nennenswerte Einschränkung des interessierten Käuferkreises anzubieten. As can be seen, the technical complexity of a remote control device outlined above is considerable and expensive significant device equipped with it. In this situation, only the concept according to the invention with a separately executed Special receiver an option, a device prepared for remote control and the additional convenience of Offering remote control through possible subsequent retrofitting without significant restriction of the interested group of buyers.
Eine vorteilhafte Weiterbildung der Erfindung liegt darin, daß der als separates Zusatzgerät ausgeführte Spezialempfänger eine eigene Netzstromversorgung besitzt.An advantageous development of the invention is that the special receiver designed as a separate additional device is a own mains power supply.
Auf diesem Wege wird vermieden, daß über das Steckverbindungskabel oder separat ein zusätzliches Netzkabel vom Zusatzgerät zum Hauptgerät hergestellt werden muß, welches hinsichtlich der Sicherheitsvorschriften ohnehin nicht unkritisch ist.In this way it is avoided that an additional power cord must be made from the additional device to the main device via the plug connection s cable or separately, which is not uncritical in any case with regard to the safety regulations.

In diesem Zusammenhang wesentlich ist die weitere Ausgestaltung der Erfindung in der Weise, daß an dem als separates Zusatzgerät ausgeführten Spezialempfänger eine oder mehrere Steckdosen für den Netzanschluß eines oder mehrerer fernzubedienenden Geräte(s) vorgesehen sind.In this context, the further development is essential of the invention in such a way that one or more of the special receiver designed as a separate additional device Sockets are provided for connecting one or more remote-controlled devices to the mains.
In Verbindung mit der separaten Stromversorgung des Spezialempfängers können dann über diese Netzverbindung mehrere Geräte, wie z. B. Rundfunkempfänger, Plattenspieler und Tonbandgerät, durch das im separaten Zusatzgerät befindliche Schaltrelais mittels Fernbedienung gemeinsam ein- bzw. ausgeschaltet werden·In connection with the separate power supply of the special receiver then several devices, such as B. radio receivers, record players and tape recorders, switched on and off together by means of the remote control using the switching relay located in the separate additional device will·
Eine spezielle Ausgestaltung der Erfindung betrifft eine drahtlose Fernbedienungseinrichtung, bei der akustische Steuersignale im Ultraschallbereich verwendet werden. Sie beinhaltet, daß der als separates Zusatzgerät ausgeführte Spezialempfänger an einer normalerweise dem Steuersignalsender zugewandten Gehäusewand ein für die Aufnahme der Ultraschallsignale dimensioniertes Mikrofon enthält.A special embodiment of the invention relates to a wireless one Remote control device with acoustic control signals be used in the ultrasonic range. It includes that the special receiver designed as a separate additional device on a housing wall normally facing the control signal transmitter, a dimensioned for receiving the ultrasonic signals Includes microphone.
Durch entsprechende Gehäusegestaltung des Zusatzgerätes und Anordnung des Ultraschall-Mikrofons in der dem Signalgeber zugewandten Gehäusewand läßt sich erreichen, daß das Zusatzgerät neben bzw. seitlich hinter dem Hauptgerät - bei guter Aufnahmeempfindlichkeit für die Steuersignale der Sendereinrichtung unauffällig aufgestellt werden kann.By designing the housing of the additional device and its arrangement accordingly of the ultrasonic microphone in the one facing the signal transmitter Housing wall can be achieved that the additional device next to or to the side behind the main device - with good recording sensitivity can be set up inconspicuously for the control signals of the transmitter device.
Schließlich liegt eine andere Weiterbildung darin, daß die Schnittstelle zwischen dem fernzubedienenden Gerät und dem als separates Zusatzgerät ausgeführten Spezialempfänger so gewählt ist, daß eine möglichst einfache Kabelverbindung zwischen beiden Geräten genügt und das fernzubedienende Gerät für den Fall der Betriebsweise ohne Fernbedienung durch die Vorbereitung für den Anschluß des separaten Spezialempfängers zugleich möglichst wenig verkompliziert und verteuert wird.Finally, another development is that the interface between the device to be remotely controlled and the as Separate additional device executed special receiver is chosen so that the simplest possible cable connection between the two Devices is enough and the device to be remotely controlled just in case the operation without remote control by the preparation for the connection of the separate special receiver at the same time as possible is little complicated and expensive.
Um dem angestrebten Ziel einer nur geringen Einschränkung des für die Anschaffung eines solchen Gerätes in Frage kommenden Käuferkreises möglichst nahezukommen, ist die günstige Wahl der Schnittstelle zwischen Haupt- und Zusatzgerät von großer Wichtigkeit. Nur wenn der überwiegende Teil des Mehraufwandes für die Fernbedienung im Zusatzgerät liegt und eine betriebssichere, unkritische Verbindung zum fernzubedienenden Gerät gegeben ist, kann dieses mit einem üblichen, ohne Fernbedienung konzipierten Modell preislich konkurrieren. Der Mehraufwand im für die Fernbedienung vorbereiteten Hauptgerät beschränkt sich dann z. B. bei einem Fernsehgerät auf den Aufwand für die Anschlußvorrichtung und die Umschaltung von Direkt- auf Fernbedienung.In order to achieve the desired goal of only a minor restriction of what can be considered for the purchase of such a device As close as possible to the group of buyers, the low-cost choice of interface between the main and additional device is of great importance Importance. Only if the major part of the additional effort for the remote control lies in the additional device and an operationally reliable, If there is a non-critical connection to the device to be remotely controlled, this can be done with a conventional one without a remote control designed model to compete in terms of price. The additional effort in the main unit prepared for the remote control is limited then z. B. in a television set on the effort for the connection device and switching from direct on remote control.
Bei einem Rundfunk-Hi-Fi-Gerät müßte man noch den zusätzlichen Schaltungsaufwand für die gleichspannungsgesteuerte Lautstärke-, Klang- und Balanceregelung in dem für die Fernbedienung vorbereiteten Hauptgerät aufwenden.In the case of a radio hi-fi device, one would have to add the additional circuitry for the DC voltage-controlled volume, Use tone and balance control in the main unit prepared for remote control.

Eine andere Weiterbildung der Erfindung betrifft eine spezielle Gestaltung des Spezialempfängers für die Fernbedienungssteuersignale und liegt darin, daß der als separates Zusatzgerät ausgeführte Spezialempfänger als nachrüstbare Eirabaueinheit in der Weise ausgeführt ist, daß sie an entsprechend vorbereiteter Stelle innerhalb des Gehäuses des fernzubedienenden Rundfunk- oder Fernsehgerätes eingesetzt wird.Another development of the invention relates to a special one Design of the special receiver for the remote control signals and lies in the fact that the special receiver, which is designed as a separate additional device, can be retrofitted Egg unit is designed in such a way that it is connected accordingly Prepared place inside the housing of the radio or television set to be remotely operated will.
Diese Konstruktion ist vorzugsweise dann vorteilhaft, wenn das Gehäuse des fernzubedienenden Gerätes ausreichend freien Raum enthält und seine Betriebsweise nach Durchführung der Nachrüstung nur noch über die Fernbedienung erfolgen soll. Das ist z. B. normalerweise bei Fernsehgeräten gegeben.This construction is preferably advantageous when the housing of the device to be remotely controlled is sufficiently free Contains room and its mode of operation should only take place via the remote control after the retrofit has been carried out. This is e.g. B. normally given in televisions.
Bei derartigen Konstruktionen des Spezialempfangsteiles als nachrüstbare Einbaueinheit und entsprechender Vorbereitung des fernzubedienenden Gerätes für den nachträglichen Einbau ist es ferner vorteilhaft, daß das für die Aufnahme der Ultraschallsignale vorgesehene Mikrofon an einer entsprechend vorbereiteten und schalldurchlässig abgedeckten Stelle an der Vorderwand des Gehäuses des fernzubedienenden Gerätes eingesetzt wird. Es ist zwar grundsätzlich möglich, auch in diesem Ausführungsfall das Mikrofon im nachrüstbaren Spezi al empfang st eil unterzubringen und an der benachbarten Gehäusewand entsprechende Schalldurchtrittsöffnungen vorzusehen. Eine bessere Ansprechempfindlichkeit für die Steuersignale erhält man aber, wenn das Mikrofon, wie zuvor vorgeschlagen, unmittelbar in der vorderen Gehäusewand des fernzubedienenden Gerätes so eingesetzt wird, daß die Steuersignale auf direktem Wege zum Mikrofon gelangen können.With such constructions of the special receiver part as a retrofittable installation unit and appropriate preparation of the device to be remotely controlled for subsequent installation It is also advantageous that the microphone provided for receiving the ultrasonic signals is connected to a corresponding prepared and sound-permeable covered position on the front wall of the housing of the device to be remotely controlled is used. In principle, it is possible to use the microphone in the retrofittable speci al reception st eil to accommodate and on the adjacent housing wall provide corresponding sound passage openings. Better sensitivity for the control signals but you get when the microphone, as previously proposed, directly in the front housing wall of the remote controlled device is used so that the control signals can reach the microphone directly.
Die im folgenden angegebene Erfxndungswexterbxldung betrifft die Umschaltung von Direkt— auf Fernbedienung bei einer Fernbedienung seinrichtung mit Ausführung des Spezialempfangsteils als nachrüstbare Einbaueinheit und liegt darin, daß der Umschalter für die Umschaltung von Direkt- auf Fernbedienung nicht in dem für die Fernbedienung vorbereiteten Hauptgerät, sondern ebenfalls in dem als nachrüstbare Einbaueinheit ausgeführten Spezialempfangsteil enthalten ist.The invention stated below relates to Switching from direct to remote control in the case of a remote control device with a special receiver as a retrofittable installation unit and lies in the fact that the switch for switching from direct to remote control not in the main unit prepared for remote control, but also in the one designed as a retrofittable installation unit Special receiving part is included.
Im allgemeinen ist es z. B. bei Fernsehempfängern nicht erforderlich, eine alternative direkte Bedienungsmöglichkeit bei Vorhandensein der Fernbedienungseinrichtung beizubehalten, da die Einstellung der Funktionen über die Fernbedienung mit Berücksichtigung des optimalen Betrachtungsabstandes von einigen Metern praktisch immer vorzuziehen ist. Ein Umschalter von Direkt- auf Fernbedienung kann also im Hauptgerät entfallen, was für dieses eine Kosteneinsparung bedeutet. Um dennoch für den Fall eines Defektes im Fernbedienungsteil bzw. auch für den Fall, daß keine einwandfreien Batterien für den Steuersender verfügbar sind, den weiteren Betrieb des Hauptgerätes zu ermöglichen, enthält der als nachrüstbare Einbaueinheit ausgeführte Spezialempfangsteil, wie zuvor vorgeschlagen, einen Umschalter, mit dessen Hilfe alle fernbedienbaren Funktionen jederzeit ohne Trennung irgendwelcher Verbindungen abgeschaltet und die ursprünglichen direkten Bedienungselemente wieder eingeschaltet werden können.In general it is e.g. B. not required for television receivers, to maintain an alternative direct control option in the presence of the remote control device, because the setting of the functions via the remote control taking into account the optimal viewing distance of a few meters is practically always preferable. A switch from direct to remote control can be done in the main unit omitted, which means a cost saving for this. Nevertheless, in the event of a defect in the remote control unit or in the event that no proper batteries are available for the exciter, continued operation of the main device, contains the special receiver, which is designed as a retrofittable installation unit, such as previously proposed a switch, with the help of which all remote-controlled functions at any time without separating any Connections can be switched off and the original direct control elements can be switched on again.
