Abstract

The invention relates to a process for programming secondary portable stations which communicate with a fixed main station. The process can be used, in particular, in drives for garage and other doors of places to which several people have access. For programming it is necessary merely to place a first secondary station against the fixed main station, whereupon said secondary station becomes the master secondary station for the further programming of slave secondary stations. It is thus possible easily to program further slave secondary stations from the master secondary station which is characterized by a corresponding indication.

Bei einem solchen Verfahren werden von einer ortsfesten Station oder Hauptstelle, welche mit einer Steuerung, die einen Mikroprozessor beinhaltet, ausgestattet ist, Informationen ausgesendet und empfangen und zu ortsveränderbaren Nebenstellen, die diese Informationen empfangen und bestätigen können, weitergegeben. Diese Hauptstelle kann beispielsweise ein Garagentor bzw. ein Torantrieb sein, der mittels eines Funkhandsenders in seinen Funktionen gesteuert werden kann, d. h. aufgrund eines Funksignales wird der Antrieb in Bewegung gesetzt, und das Tor bzw. das Garagentor öffnet oder schließt sich.The invention relates to a method for transmitting information according to the preamble of claim 1. In such a method are from a fixed station or main station, which with a Control, which includes a microprocessor, is equipped with information sent and received and to portable extensions, who can receive and confirm this information. This main unit can be a garage door or a Be door operator, the functions of a radio hand transmitter can be controlled, d. H. the drive is switched on due to a radio signal set in motion and the gate or garage door opens or closes.

Es sind hinlänglich Handsender für derartige Antriebe bekannt, die über sogenannte Dipschalter programmiert werden können, d.h. der für die Steuerung zulässige Code wird in den Handsendem manuell eingegeben.There are sufficiently known hand-held transmitters for drives of this type which So-called dip switches can be programmed, i.e. the one for the Control permissible code is entered manually in the handheld transmitter.

Femer sind Anlagen der vorbeschriebenen Art bekannt geworden, bei denen zur Programmierung der Nebenstellen diese über ein Stecksystem fest mit der ortsfesten Hauptstelle verbunden werden und dann aufgrund eines in der ortsfesten Hauptstelle ablaufenden Programmes diese mit dem entsprechenden Zugangscode für die Bedienung des Antriebes ausgestattet werden.Systems of the type described above have also become known, in which for programming the extensions via a plug-in system be connected to the fixed main station and then due to a in the stationary main program, this with the corresponding Access code equipped for operating the drive become.

Der DE-OS 41 30 904 ist ein Verfahren zur berührungslosen Energie- und Datenübertragung nach dem Transponderprinzip zu entnehmen. Bei diesem Verfahren werden berührungslos Energie und Daten empfangen und ausgesendet. Die Energieübertragung erfolgt bei solchen Systemen mittels Antennenspulen.DE-OS 41 30 904 is a method for non-contact energy and Data transmission based on the transponder principle. With this Processes receive energy and data without contact sent out. In such systems, the energy transfer takes place by means of Antenna coils.

Ein Verfahren zur Eingabe von Kenndaten in einen Mikroprozessor eines Kraftfahrzeugschlüssels, der mit einem Sender ausgestaltet ist, wird in der DE 42 36 863 A1 beschrieben. Es werden dabei die von einem Pseudo-Zufallsgenerator nach einem Algorithmus erzeugten Kenndaten zuerst in ein Kenndatenprogrammiergerät eingespeist und erst danach an den Kraftfahrzeugschlüssel weitergegeben.A method of entering characteristics into a microprocessor Motor vehicle key, which is designed with a transmitter, is in the DE 42 36 863 A1 described. There are those from a pseudo-random generator characteristics generated according to an algorithm first in a characteristic data programming device and only then to the Motor vehicle key passed.

Die Aufgabe der Erfindung ist es, den bekannten Stand der Technik dahingehend zu verbessern, daß die Übertragung der Identifikationscodes, d.h. die entsprechenden Informationen zur Identifizierung des ortsveränderbaren Systemes mit dem ortsfesten System so zu verbessern, daß eine leichte Programmierung der ortsveränderbaren Nebenstellen gewährleistet ist.The object of the invention is the known prior art to improve that the transmission of identification codes, i.e. the appropriate information to identify the portable System to improve with the fixed system so that a Easy programming of the portable extensions guaranteed is.

Die Aufgabe wird durch die Merkmale nach Anspruch 1 gelöst. Es wird insbesondere ein Verfahren geschaffen, mittels dem die Informationen von der ortsfesten Hauptstelle zur Codeübertragung drahtlos ausgesendet werden und diese an ortsveränderbare Nebenstellen übertragen werden. Die Übertragung der Codeauswahl erfolgt nach dem Transponderprinzip, d.h. sowohl in der ortsfesten Hauptstelle als auch in der ortsveränderbaren Nebenstelle sind Spulen oder Systeme aus Spulen und/oder Kondensatoren vorhanden, die Informationen der Codes aufnehmen und abgeben können. Ein solches System wird beispielsweise bei Garagentoren angewendet, so daß das lästige Stecken der Handsender als ortsveränderbare Nebenstelle zur Programmierung entfallen kann, bzw. es kann das umständliche Öffnen und Verstellen der Programmierschalter unterbleiben. Beim erfindungsgemäßen Gegenstand wird das Programmierverfahren dahingehend vereinfacht, daß die ortsveränderbaren Nebenstellen nicht an oder in die ortsfeste Hauptstelle gesteckt werden müssen. Vielmehr ist es so, daß nur eine der ortsveränderbaren Nebenstellen in die Nähe der ortsfesten Hauptstelle gebracht werden muß, so daß die von der Hauptstelle ausgesendeten Funksignale von dem ortsfesten Transpondersystem abgegeben und von dem ortsveränderbaren Transpondersystem der Nebenstelle aufgenommen werden können.The object is achieved by the features of claim 1. It will in particular created a procedure by means of which the information from the fixed main station for code transmission be sent wirelessly and this to portable extensions be transmitted. The code selection is transmitted according to the transponder principle, i.e. both in the fixed head office and Coils or systems are also off in the portable extension Coils and / or capacitors are present, the information of the codes can record and deliver. Such a system is, for example applied to garage doors, so that the annoying insertion of the handheld transmitter can be omitted as a changeable extension for programming, or the cumbersome opening and adjustment of the programming switches remain under. In the subject of the invention Programming procedures simplified in that the portable Extensions are not plugged into or into the fixed main station Need to become. Rather, it is the case that only one of the relocatable Extensions must be brought close to the fixed main station, so that the radio signals emitted by the main station from the Fixed transponder system delivered and by the portable The transponder system of the extension can be added.

Ist eine solche Nebenstelle mit dem berechtigten, aus einem Zufallsgenerator ausgewählten Zutrittsberechtigungscode ausgestattet, so wird diese erste Nebenstelle durch die Programmierung gleichzeitig als Master initialisiert. Es findet dabei ferner mit der Programmierung ebenfalls eine Rückmeldung der empfangenen Daten von der programmierten Nebenstelle auf die Hauptstelle statt, um eine Überprüfung des ordnungsgemäßen Programmierungsvorganges zu ermöglichen.Is such an extension with the authorized one, from a random number generator selected access authorization code, it will be first extension initialized by programming at the same time as master. It also finds one with the programming Feedback of the received data from the programmed extension to the main office for a review of the proper To enable the programming process.

Der von einem Zufallsgenerator in Verbindung mit einem Mikroprozessor ausgewählte Zutrittsberechtigungscode hat eine bestimmte Bitlänge und Bitmuster, die von außen nicht beeinflußbar sind und auch nicht über Schalter gesetzt werden können. Wird die Taste beispielsweise an der Hauptstelle 'Information übertragen' betätigt, so wird durch bloßes Aneinanderbringen der Nebenstelle an die Hauptstelle dieser Funkcode, d.h. Informationen, zur Identifizierung und damit der ausgewählte Zutrittsberechtigungscode übertragen. Diese Übertragung geschieht auf eine Mastemebenstelle nur einmal. Zur Übertragung ist keine mechanische Kopplung zwischen der Hauptstelle und der Nebenstelle notwendig.The one from a random generator in conjunction with a microprocessor selected access authorization code has a certain bit length and Bit patterns that cannot be influenced from the outside and also not via Switches can be set. For example, if the button on the Main unit 'transmit information' is activated by simply bringing them together the extension to the main station this radio code, i.e. Information, for identification and thus the selected access authorization code transfer. This transfer takes place on a master branch once only. There is no mechanical coupling for transmission between the head office and the extension.

Die Hauptstelle erkennt beispielsweise auch automatisch bei einer ersten Installation, daß ein in die Nähe gebrachter Handsender (Nebenstelle) vorhanden ist und überträgt diesem die Informationen in Form eines Telegrammes. Nach Übertragung der Bitmuster wird gleichzeitig eine Rückmeldung gesendet, so daß ein Kommunikationsprotokoll vorhanden ist. Dieses ganze kann auf einem Kanal, d.h. im Halbduplexverfahren abgewickelt werden, jedoch ist es auch möglich im Vollduplexverfahren diese Informationen auszutauschen. Die Nebenstellen können mit einer Batterie versehen sein, jedoch ist es auch möglich, daß diese Nebenstellen ohne eine zusätzliche Stromversorgung arbeiten.For example, the main station automatically detects the first one Installation that a handheld transmitter (extension) brought into the vicinity is available is and transmits the information to it in the form of a telegram. After the bit pattern has been transmitted, a response is received at the same time sent so that a communication protocol is available. All of this can be done on one channel, i.e. processed in half-duplex but it is also possible to do this in full duplex Exchange information. The extensions can be powered by a battery be provided, but it is also possible that these extensions without an additional power supply will work.

Ist in der ersten Nebenstelle der Zutrittsberechtigungscode in Form eines Bitmusters übernommen worden, so stellt diese 'Master'-Nebenstelle sicher, daß weitere Nebenstellen, wie sie beispielsweise bei Großgaragen vorhanden sind, nicht mit der Hauptstelle, sondern nur mit der 'Master'-Nebenstelle programmiert werden können. Dieses stellt für den Benutzer eine enorme Vereinfachung dar, da auch große Personenkreise eine Abneigung gegen das Einstellen verschiedener Bitmuster auf manuelle Art haben.Is the access authorization code in the form of a in the first extension Bit pattern has been adopted, this 'master' extension ensures that additional extensions, such as those found in large garages are available, not with the main unit, but only with the 'master' extension can be programmed. This provides a for the user enormous simplification, since even large groups of people dislike against setting different bit patterns in a manual way.

Eine solche Programmierung kann beispielsweise nach dem Verfahren derart ablaufen, daß zwei Sender aneinander gelegt werden, weil beide mit dem entsprechenden Transpondersystem ausgestattet sind, und durch das Betätigen einer Taste wird der von der Hauptstelle auf den Master übertragene Zutrittberechtigungscode auf weitere Handsender bzw. die Nebenstellen übertragen, es entsteht dadurch eine 'Slave'-Nebenstelle.Such programming can be done, for example, using the method run in such a way that two transmitters are put together because both with the appropriate transponder system, and by that Pressing a key transfers the one transmitted from the main station to the master Access authorization code to other handheld transmitters or the extensions transmitted, this creates a 'slave' extension.

Eine Programmierung kann nur von einer 'Master'-Nebenstelle ausgehen, nicht von dem als weiteres Duplikat von der Mastemebenstelle geschaffenen 'Slave'-Nebenstelle. Es ist jedoch möglich, mit einem Master unbegrenzt weitere Nebenstellen (Slaves) zu programmieren. Somit ist nur in einer der Nebenstellen das Masterbit aktiviert und alle anderen Nebenstellen zeichnen sich dadurch aus, daß sie zur Öffnung des Tores eingesetzt werden können, aber zur Programmierung nicht. Dieses ist ein besonderes Sicherheitsmerkmal, so daß ganz bewußt nur mit einer Nebenstelle eine Programmierung und damit weitere Zugangsberechtigung für die anderen Nebenstellen geschaffen werden kann.Programming can only start from a 'master' extension, not from that created as a further duplicate by the master branch 'Slave' extension. However, it is possible with an unlimited master to program additional extensions (slaves). So only in one of the extensions activates the master bit and all other extensions are characterized by the fact that they are used to open the gate can be, but not for programming. This is special Security feature, so that deliberately only with one extension Programming and thus further access authorization for the others Extensions can be created.

Zu den vorbeschriebenen einkanaligen Systemen kann es auch mehrkanalige Haupt- und Nebenstellen geben, bei denen beispielsweise in einer Nebenstelle sowohl auf einem Kanal ein 'Master' und auf einem anderen Kanal ein 'Slave' vorhanden sein kann. In diesem Zusammenhang sei darauf hingewiesen, daß auch zwei 'Master'-Nebenstellen innerhalb einer Nebenstelle möglich sind.In addition to the single-channel systems described above, multi-channel systems can also be used Give main and extensions, for example in one Extension both a 'master' on one channel and another Channel a 'slave' can be present. In this context, be on it noted that there are also two 'master' extensions within one extension possible are.

In welchem Status sich schließlich eine solche Nebenstelle befindet, kann durch eine optische Anzeige kenntlich gemacht werden.The status of such an extension can be be identified by a visual display.

Durch das vorbeschriebene Verfahren ist es möglich, eine Programmierung von Nebenstellen insbesondere für Öffnung von Garagentoren und sonstigen Toren zu schaffen, ohne daß eine mechanische Kopplung zwischen dem Antrieb bzw. Hauptstelle und den Nebenstellen (Handsendern) vorgenommen werden muß. Dieses stellt eine enorme Kostenerspamis dar, weil keine Steckverbindungen, die nur eine begrenzte Anzahl an Steckzyklen zulassen, verwendet werden. Gerade bei Garagentorantrieben, die an der Decke einer Garage installiert sind, ist es sehr schwierig, Empfänger auf die Steckverbindungen zu stecken, weil in der Regel der direkte Blickkontakt nicht vorhanden ist. Dadurch kommt es zu Beschädigungen der Steckverbindungen, was eine Programmierung der Empfänger dann unmöglich macht. The above described method makes programming possible of extensions, in particular for opening garage doors and other gates without creating a mechanical coupling between the drive or main unit and the extensions (hand transmitters) must be made. This represents an enormous cost savings because no connectors that have a limited number of Allow mating cycles can be used. Especially with garage door operators, installed on the ceiling of a garage, it is very difficult To plug receivers on the connectors because usually the there is no direct eye contact. This leads to damage of the connectors, which is programming the receiver then makes impossible.

In vielen Fällen ist es so, daß z.B. Garagentorantriebe neben der eigentlichen Funktion, nämlich der Betätigung des Tores, auch mit einer Beleuchtungseinrichtung ausgestattet sind. Diese Beleuchtung muß über einen separaten Schalter ein- und ausgeschaltet werden.In many cases, e.g. Garage door operators next to the actual one Function, namely the operation of the gate, also with a lighting device are equipped. This lighting must have one separate switches can be switched on and off.

Durch den erfindungsgemäßen Gegenstand kann diese Funktion der Beleuchtungsein- und -ausschaltung auch übernommen werden. So kann ein Codetaster in der Hauptstelle vorhanden sein, welcher weitere Funktionen wie z.B. die Beleuchtungsschaltung realisiert. Diese zweite Codeinformation ist nur für zusätzliche Funktionen. Eine Realisierung kann dadurch geschehen, daß z.B. bei einem ersten Tastendruck einer separaten Taste in der Nebenstelle das Garagenlicht eingeschaltet wird, und bei einer erneuten Betätigung der Taste das Licht wieder gelöscht wird. Die notwendige Codierung und damit die Übertragung des zulässigen Codes geschieht in der gleichen Weise wie beim IdentifikationscodeThis function of the lighting unit can be and switching off are also taken over. So one can Code switch in the main unit, which other functions such as. realized the lighting circuit. This second code information is only for additional functions. A realization can happen that e.g. at the first press of a separate key the garage light is switched on in the extension, and when it is switched on again Pressing the button the light is extinguished again. The necessary Coding and thus the transmission of the permissible code happens in the same way as for the identification code

Mit dieser Art von Nebenstelle läßt sich sowohl ein Tor öffnen und schließen, als auch die Beleuchtung ein- und ausschalten.This type of extension can be used to open and close a gate, as well as switching the lighting on and off.
