Description

Die Erfindung bezieht sich auf ein Fernsteuersystem für Großräume nach Gattungsbegriff von Patentanspruch 1. Es arbeitet mit Sendern und Dekodern in Empfängern, von denen Aktoren geschaltet werden. Die Sender geben hierzu geeignete Telegramme ab.The invention relates to a remote control system for large rooms according to the preamble of claim 1. It works with transmitters and decoders in receivers, of which actuators are switched. The transmitters send suitable telegrams for this.

Werden in Großräumen Fernsteuerungen auf der Basis von Infrarot-Übertragungen eingerichtet, so hat jeder Empfänger einen gewissen Empfangsbereich, der durch die Gerätecharakteristik, die Sender-Empfänger-Leistung sowie die Empfangsverhältnisse gegeben ist. Idealisiert kann man von kugelförmigen Empfangsbereichen ausgehen, die auf eine gedachte Installationsebene projiziert, kreisförmigen Empfangsbereichen entspricht. Innerhalb des Empfangsbereichs kann ein Sender einen Empfänger unter gegebenen Verhältnissen erreichen.If remote controls based on infrared transmissions are set up in large areas, each receiver has a certain reception range, which is given by the device characteristics, the transmitter-receiver power and the reception conditions. Ideally, spherical reception areas can be assumed, which project onto an imaginary installation level and correspond to circular reception areas. Within the reception area, a transmitter can reach a receiver under given conditions.

Aufgrund dieser Grenzen der Reichweite ist es schwierig, Schaltvorgänge über mehrere Erfassungsbereiche hinweg sicherzustellen. Das ist jedoch in vielen Fällen wünschenswert, beispielsweise um eine Wechselschaltung unter Einbeziehung der gesamten Raumbeleuchchtung durch Infrarotsender aus verschiedenen Erfassungsbereichen heraus sicherzustellen. Da in der Praxis ein Empfänger für Infrarot-Übertragungsmedium im allgemeinen aus den Komponenten Vorverstärker und Dekoder besteht, der einen Aktor bzw. ein Schaltleistungsteil ansteuert, könnte man daran denken, zwischen Vorverstärker und Dekoder entsprechend lange Zuleitungen zu setzen. Auf dieser Leitung könnte das Format der Infrarotübertragung oder auch ein abgeändertes Format bzw. Telegramm weitergeleitet werden. Wenn man danach den Empfangsbereich eines Dekoders erweitern möchte, hätte man Vorverstärker auch in benachbarten Erfassungsbereichen zu installieren. Eine derartige Installation würde jedoch soviele Eingänge und Vorverstärker benötigen, wie insgesamt je Dekoder erfassungsbereiche zu bedienen wären. Dennoch hätte man keine definierten Schaltzustände. Es könnte also vorkommen, daß mit einer Betätigung eines Handbedienungsorgans, beispielsweise einer Taste, ein Einschaltbefehl gegeben würde, dem einige Aktoren nicht folgen würden, so daß bei einem zweiten Schaltbefehl die eingeschaltete Installationsguppe ausschalten und die zunächst ausgeschaltete einschalten würde. Dieser unbefriedigende Schaltzustand wäre nicht zu beheben.Because of these range limits, it is difficult to ensure switching operations across multiple detection areas. However, this is desirable in many cases, for example in order to ensure a two-way switching including the entire room lighting by means of infrared transmitters from different detection areas. Since in practice a receiver for infrared transmission medium generally consists of the components preamplifier and decoder, which controls an actuator or a switching power unit, one could think of placing correspondingly long leads between the preamplifier and decoder. The format of the infrared transmission or a modified format or telegram could be forwarded on this line. If you then want to expand the reception range of a decoder, you would have to install preamplifiers in neighboring detection ranges. However, such an installation would require as many inputs and preamplifiers as would be required to operate a total of each decoder detection area. However, there would be no defined switching states. So it could happen that with an actuation of a manual control element, for example a button, a switch-on command would be given which some actuators would not follow, so that a second switch command would switch off the switched-on installation group and switch on the switch-off which was initially switched off. This unsatisfactory switching state could not be remedied.

Eine derartige Installation hätte auch den Nachteil, verhältnismäßig aufwendig zu sein und organisatorisch bedingte nachträgliche Änderungen nur erschwert zu ermöglichen. Außerdem wäre die Anzahl der Erfassungsbereiche auf die Anzahl begrenzt, die durch die installierten Eingänge der Dekoder vorgegeben wären. auch Multiplexverfahren scheiden wegen der unzulässigen Verlängerung der Reaktionszeiten eines derartige Fernsteuersystems aus.Such an installation would also have the disadvantage of being relatively complex and making it difficult to make subsequent changes due to organizational reasons. In addition, the number of detection areas would be limited to the number that would be determined by the installed inputs of the decoder. multiplexing methods are also ruled out because of the impermissible extension of the response times of such a remote control system.

Der Erfindung liegt die Aufgabe zugrunde, ein Fernsteuersystem für Großräume zu entwickeln, das eine Erweiterung der Erfassungsbereiche mit einfachen Mitteln in der Montage und bei nachträglichen Änderungen ermöglicht.The invention has for its object to develop a remote control system for large rooms, which allows an expansion of the detection areas with simple means in the assembly and subsequent changes.

Die Lösung der geschilderten Aufgabe erfolgt durch ein Fernsteuersystem nach Patentanspruch 1. Danach sind zwei oder mehrere Dekoder untereinander durch Leitung verbunden, die im Zugriff auf diese Leitung mit Kollisionserkennung arbeiten. Die Telegramme sind mit Kodierungsmerkmalen für den Schaltzustand "ein", "aus" versehen. Auf den Verbund aus Dekodern wird vom jeweiligen, durch gültiges Telegramm aktivierten Dekoder die gesamte ankommende Adresse oder auch eine übersetzte Adresse weitergegeben. Zusätzlich wird der aktuelle Schaltzustand für das Leistungsteil vom aktiven Dekoder weitergegeben. Unabhängig vom Schaltzustand wird durch das empfangene Telegramm ein bestimmter Schaltzustand bestätigt oder verlangt, so daß ein Außertrittfallen der Aktoren und der zugeordneten Installationsgeräte nicht möglich ist. Andere Aktoren weiterer, über Leitung angeschlossener Dekoder ziehen durch die Zwangssynchronisation gleich. Bei mehrfacher Ersterkennung eines Telegramms durch mehrere Dekoder wird ein störender Mehrfachzugriff auf die verbindende Leitung durch Kollisionserkennung in an sich bekannter Weise vermieden. Bei zwei erkennenden Dekodern sendet also nur der schnellere Dekoder auf die Leitung.The described task is solved by a remote control system according to claim 1. Then two or more decoders are connected to one another by a line, which operate with access to this line with collision detection. The telegrams are provided with coding features for the switching status "on", "off". The entire incoming address or a translated address is passed on to the network of decoders by the respective decoder activated by a valid telegram. In addition, the current switching status for the power section is passed on by the active decoder. Regardless of the switching state, the received telegram confirms or requests a specific switching state, so that the actuators and the associated installation devices cannot fall out. Other actuators of other decoders connected via line pull the same due to the forced synchronization. If a telegram is recognized several times by several decoders, disruptive multiple access to the connecting line by collision detection is avoided in a manner known per se. If there are two decoders, only the faster decoder sends on the line.

Die verbindende Leitung kann ein Bus- oder je nach Anwendungsfall auch ein Einfachleiter mit Rückleitung über Erde sein.The connecting line can be a bus or, depending on the application, a single conductor with a return line to earth.

Vorteilhafterweise kann die Leitung durch Trennstellen mit der ergebnisbezogenen Wirkungsweise von Steckverbindern an organisatorischen Raumachsen trennbar bzw. erweiterungsfähig ausgeführt sein. Das Fernsteuersystem kann dann organisatorischen Änderungen, neu einzuführenden Wänden, oder bei zu entfernenden Wänden an die neuen Gegebenheiten besonders leicht angepaßt werden.Advantageously, the line can be made separable or expandable by separating points with the result-based mode of action of plug connectors on organizational spatial axes. The remote control system can then be adapted to the new circumstances particularly easily organizational changes, new walls to be introduced, or walls to be removed.

Die Erfindung soll anhand eines in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispiels näher erläutert werden:

  • Zu einem Fernsteuersystem sind beispielhaft zwei Übertragungsbereiche wiedergegeben. Das Fernsteuersystem arbeitet mit Sendern 1 und Dekodern 2 in Empfängern 3. Die Dekoder 2 bzw. die Empfänger 3 Schalten Aktoren 4 bzw. Schaltleistungsteile. Die Aktoren 4 sind mit den Empfängern im einfachsten Fall über Leitung verbunden. Im wesentlichen bestehen die Empfänger 3 aus einem Vorverstärker 5 für das über das Übertragungsmedium, beispielsweise Infrarotlicht, empfangene Telegramm. Die Dekoder 2 sind untereinander durch Leitung 6 miteinander verbunden. Jeder Dekoder hat einen Empfangsbereich, in dem er Telegramme von Sendern empfangen kann. Im Ausführungsbeispiel sind von Empfangsbereichen 7 der Empfangsbereich Ek und der Empfangsbereich Ek + dargestellt. Diese Empfangsbereiche sind Teil eines Fernsteuersystems für einen Großraum mit der Wand 8 und den organisatorischen Raumachsen 9. An den Dekoderverbund können auch Sensoren angeschlossen werden. Diese Sensoren können vorteilhafterweise als Schwellwertschalter ausgeführt sein und bei jedem Schaltstellungswechsel wunschgemäß ein "ein" oder "aus" an die am Sensor zuvor eingestellte Adresse über die verbindende Leitung weitergeben. Aktoren an Dekodern, die auf diese Adresse programmiert sind, werden dann definiert geschaltet.
The invention will be explained in more detail with reference to an exemplary embodiment shown roughly schematically in the drawing:
  • Two transmission ranges are shown as examples for a remote control system. The remote control system works with transmitters 1 and decoders 2 in receivers 3. The decoders 2 and the receivers 3 switch actuators 4 and switching power parts. In the simplest case, the actuators 4 are connected to the receivers via a line. The receivers 3 essentially consist of a preamplifier 5 for the Te received via the transmission medium, for example infrared light legram. The decoders 2 are interconnected by line 6. Each decoder has a reception area in which it can receive telegrams from transmitters. In the exemplary embodiment, reception areas Ek and reception area Ek + are shown of reception areas 7. These reception areas are part of a remote control system for a large room with the wall 8 and the organizational room axes 9. Sensors can also be connected to the decoder network. These sensors can advantageously be designed as threshold switches and, as desired, pass an "on" or "off" to the address previously set on the sensor via the connecting line whenever the switch position is changed. Actuators on decoders that are programmed to this address are then switched in a defined manner.

Um die Leitung besonders leicht verlängern oder verkürzen zu können, sind Trennstellen 10 vorteilhaft, die günstigerweise an organisatorischen Raumachsen angeordnet werden können. Diese Trennstellen können auf die verschiedenartigste an sich bekannte Weise ausgeführt sein, wenn sie bezogen auf das Ergebnis die Wirkungsweise von Steckverbindern sicherstellen.In order to be able to lengthen or shorten the line particularly easily, separation points 10 are advantageous, which can advantageously be arranged on organizational spatial axes. These separating points can be designed in the most varied of ways known per se, if they ensure the operation of plug-in connectors based on the result.

Die Trennstellen können auch mittels Software erzeugt werden, indem verschiedene Adressen den entsprechenden verschiedenen Raumbereichen zugeordnet werden. Raumübergreifende Funktionen können verwirklicht werden, indem einige der Adressen für mehrere Raumbereiche gleich gewählt werden. Diese gleichen Adressen ermöglichen dann raumübergreifende Funktionen für die entsprechenden Raumbereiche.The separation points can also be generated by software by assigning different addresses to the corresponding different room areas. Cross-room functions can be realized by selecting some of the addresses for several room areas. These same addresses then enable cross-room functions for the corresponding room areas.
