Abstract

In this wireless remote control system, control signals and reporting-back signals are bidirectionally transmited between at least one portable transmitter-receiver unit, a stationary transmitter-receiver unit and a control. The portable transmitter-receiver unit contains a microprocessor and is carried, for example, by hand or in a clothing pocket. Control commands are input, depending upon their frequency of occurrence, by way of a ten-key keyboard, fixed keys or stored in a storage and transmitted as control signals via an operating mode selector switch selectively in either one of the operating modes "manually by push-button" or "automatically, permanently". The signalling is non-public and on an indicator. The stationary transmitter-receiver unit with microprocessor is mounted stationarily in the transmission range of the associated portable transmitter-receiver unit and communicates the received control commands to the control. This remote control permits location-independent input of public and non-public operating requests into elevator installations and thereby a conveniently and secure call issue to protected storys. The method and the equipment can likewise be used for operating doors, escalators, turnstile and so forth and thus are generally suitable for controlling access and facilitating personnel traffic in buildings.

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Einrichtung zur gesicherten und komfortablen Eingabe von Steuerbefehlen, insbesondere bei Aufzugsanlagen, wobei Steuerbefehle an einem portablen, drahtlosen Sender eingegeben und von diesem als kodierte Steuersignale ausgesendet werden, welche von einem stationären Empfänger empfangen und nach Dekodierung einer Steuerung zugeleitet werden und wobei ferner die steuerseitige Registrierung und Ausführung dieser Steuerbefehle signalisiert wird. Mit solchen Verfahren soll ermöglicht werden, Steuerbefehle ohne Benützung standortgebundener Befehlsgeber, in eine Steuerung einzugeben. Damit können bei Aufzugsanlagen Rufe nach gesicherten oder geschützten Stockwerken wie auch normale Rufe ohne Verwendung der Stockwerk- oder Kabinenruftasten aus der näheren Umgebung eines Aufzuges standortunabhängig eingegeben werden.The invention relates to a method and a device for secure and convenient input of control commands, in particular in elevator systems, wherein control commands are input to a portable, wireless transmitter and transmitted by the latter as coded control signals, which are received by a stationary receiver and after decoding one Control are supplied and the control side registration and execution of these control commands is also signaled. Such methods are intended to enable control commands to be entered into a controller without the use of location-specific command transmitters. With elevator systems, calls for secured or protected floors, as well as normal calls, can be entered from anywhere in the vicinity of an elevator without using the floor or car call buttons.

Beim konventionellen Betrieb einer Steuerung ist die Eingabe der Steuerbefehle oft an mechanische Befehlsgeber gebunden und somit standortabhängig. Dies kann den Bedienungskomfort beeinträchtigen und einen Einsatz der Steuerung für Sicherheitszwecke erschweren. Gewünscht ist deshalb in vielen Fällen eine freizügige, standortunabhängige Eingabe der Steuerbefehle z.B. mittels drahtloser Fernbedienung.In the conventional operation of a controller, the input of the control commands is often linked to mechanical command transmitters and is therefore location-dependent. This can affect the ease of use and make it difficult to use the controller for safety purposes. In many cases, therefore, it is desirable to be able to enter the control commands freely, regardless of location, e.g. using wireless remote control.

So sind aus der DE-OS 36 31 179 ein Verfahren und eine Einrichtung zum privaten oder allein berechtigten Bedienen eines Fahrstuhles bekannt geworden, wobei ein drahtloser Sender, ein Empfänger sowie eine Kabinensteuerungsanlage vorgesehen sind, die nach dem Oberbegriff des Anspruches 1 aufeinander einwirken. Dabei gibt ein Fahrgast einen Kabinenruf oder eine andere Kabinenanforderung durch Betätigung eines (in der Hand) tragbaren, drahtlosen, verbergbaren Senders ein, der eine oder mehrere Tasten aufweist, welche jeweils ein bestimmtes Stockwerk bezeichnen und die in Kombination benutzt werden können, um Zutritt zu einem gesicherten Stockwerk zu erhalten oder andere Funktionen anzuweisen, z.B. Nothalt oder stummer Notruf. Der Fahrgast trägt den Fernbedienungs-Sender z.B. in einer Kleider-Tasche und gibt einen Ruf z.B. für normale Zwecke oder für Sicherheitszwecke oder eine andere Funktion durch Betätigung der Tasten ein. Eine in der Kabine vorgesehene Empfangsantenne oder ein Sensor empfängt den übertragenen Befehl, der dann auf dieselbe Weise zur Kabinensteuerung übertragen wird, wie wenn er unmittelbar an den Kabinentasten eingegeben worden wäre. In Abhängigkeit vom eingegebenen Befehl kann die Kabinensteuerung je nach der dem Befehl entsprechenden Bedienungsart, einen Knopf an der Kabinenbedientafel aufleuchten lassen und den eingegebenen Befehl so quittieren.Thus, from DE-OS 36 31 179 a method and a device for private or sole authorized operation of an elevator have become known, wherein a wireless transmitter, a receiver and a cabin control system are provided, which interact according to the preamble of claim 1. A passenger makes a cabin call or another cabin request Actuation of a (handheld) portable, concealable transmitter that has one or more buttons, each of which designates a particular floor and which can be used in combination to gain access to a secured floor or to instruct other functions, e.g. Emergency stop or silent emergency call. The passenger carries the remote control transmitter, for example in a clothes pocket, and enters a call, for example for normal purposes or for security purposes or another function, by pressing the buttons. A receiving antenna or sensor provided in the cabin receives the transmitted command, which is then transmitted to the cabin control in the same way as if it had been entered directly on the cabin buttons. Depending on the command entered, the cabin control can, depending on the type of operation corresponding to the command, light up a button on the cabin operating panel and thus acknowledge the command entered.

Ein erster Nachteil bei diesem Verfahren ergibt sich aus dem Umstande, dass ein portabler Sender unilateral auf einen stationären Empfänger wirkt und demnach keine Verbindung in umgekehrter Richtung besteht. Es ist deshalb nicht möglich von der Steuerung zum portablen Sender zu signalisieren, um z.B. bei Aufzugsanlagen die Registrierung eines Rufes durch Anzeige auf dem portablen Sender privat zu quittieren. Folglich muss die Quittierung von Rufen auf dem Kabinentableau erfolgen, also öffentlich und für jedermann sichtbar, was eine gesicherte Aufzugsbedienung beeinträchtigen kann.
Auch hat sich als nachteilig erwiesen, dass keine Möglichkeit besteht, öfters verwendete Steuerbefehle im portablen Sender abzuspeichern damit sie im Bedarfsfalle, z.B. über Fixtasten direkt ausgesendet werden können. Steuerbefehle müssen also jedes Mal neu eingegeben und ausgesendet werden, was den Bedienungskomfort beeinträchtigt, besonders dann, wenn der gleiche Steuerbefehl täglich mehrmals verwendet werden muss.A first disadvantage with this method arises from the fact that a portable transmitter acts unilaterally on a stationary receiver and therefore there is no connection in the opposite direction. It is therefore not possible to signal from the control to the portable transmitter, for example to privately acknowledge the registration of a call in elevator systems by displaying it on the portable transmitter. As a result, calls must be acknowledged on the car panel, i.e. publicly and for everyone to see, which can affect the safe operation of the elevator.
It has also proven to be disadvantageous that there is no possibility of storing frequently used control commands in the portable transmitter so that they can be transmitted directly if necessary, for example using fixed keys. Control commands must therefore be re-entered and sent each time, which affects the ease of use, especially when the same control command has to be used several times a day.

Ferner ist im Verfahren gemäss DE-OS 36 31 179 keine Automatik beim privaten Bedienen eines Fahrstuhles vorgesehen. Vielmehr muss jeder Steerbefehl einzeln und manuell am portablen Sender eingegeben werden, worauf er dann sofort oder nach einer eingestellten Zeitverzögerung ausgesendet wird. Besonders bei Aufzügen in Hotels ist es aber vorteilhaft, wenn die Steuerbefehle selbsttätig und permanent ausgesendet werden, so dass ein Hotelgast ohne Manipulation und nach beliebigem Zeitplan auf seine Etage und in sein Zimmer gelangen kann. Sowohl die manuelle wie auch die automatische aber zeitlich fixierte Befehlsgabe mindern den Bedienungskomfort, da sie den Hotelgast zwingen, sein Gepäck abzustellen und wieder aufzunehmen bzw. sich nach einem vorgegebenen Zeitplan zu bewegen.
Weiter muss ein Mangel grundsätzlicher Art darin gesehen werden, dass das vorgenannte Verfahren keine Programmierbarkeit aufweist und seine Betriebsparameter und Kenngrössen somit nicht leicht und rasch geändert werden können. Ein solches Verfahren ist deshalb wenig flexibel und einem Einsatz für sicherheitstechnische Anwendungen schlecht angepasst, wenn ein Sicherheitsdispositiv wie z.B. der Schliessplan eines Gebäudes aus sicherheitstechnischen Erwägungen in unregelmässigen Zeitintervallen geändert werden soll. Hier will die Erfindung Abhilfe schaffen.Furthermore, in the method according to DE-OS 36 31 179 no automatic is provided for the private operation of an elevator. Rather, each steer command must be entered individually and manually on the portable transmitter, whereupon it is then transmitted immediately or after a set time delay. Particularly when it comes to lifts in hotels, it is advantageous if the control commands are sent automatically and permanently, so that a hotel guest can get to his floor and his room without manipulation and according to any schedule. Both the manual and the automatic, but time-fixed commands, reduce the ease of use, since they force the hotel guest to put their luggage down and pick them up again or to move according to a predefined schedule.
Furthermore, a fundamental shortcoming must be seen in the fact that the aforementioned method has no programmability and its operating parameters and parameters cannot therefore be changed easily and quickly. Such a method is therefore not very flexible and poorly adapted for use in security applications if a security disposition such as the locking plan of a building is to be changed at irregular time intervals for security reasons. The invention seeks to remedy this.

Der antragsgemässen Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren und eine entsprechende Einrichtung zu schaffen, welche die Eingabe von Steuerbefehlen für Sicherheitszwecke wie auch für normale Zwecke gesichert und komfortabel gestalten und bei der Steuerung von Aufzügen wie auch anderer technischer Einrichtungen gleichermassen anwendbar sind. Verfahren und Einrichtung sollen insbesondere auch so gestaltet sein, dass ihre Betriebsparameter und Kenngrössen leicht und rasch geändert werden können, damit eine Anpassung auch bei Sicherheitsdispositiven möglich ist, die unterschiedlich sind, oder die zur Wahrung der Sicherheit in unregelmässigen Zeitabständen geändert werden müssen.The application according to the invention is therefore based on the object of providing a method and a corresponding device which secure and comfortable the input of control commands for security purposes as well as for normal purposes and which are equally applicable to the control of elevators and other technical devices. In particular, the method and device should also be designed in such a way that their operating parameters and parameters can be changed easily and quickly, so that adaptation is possible even with security devices that differ, or that have to be changed at irregular intervals to maintain security.

Gelöst wird diese Aufgabe erfindungsgemäss mit den Mitteln, wie sie in den Fassungen der unabhängigen Patentansprüche gekennzeichnet sind. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with the means as characterized in the versions of the independent claims. Advantageous further developments are specified in the dependent claims.

Darüber hinaus weisen Verfahren und Einrichtung, die mit diesen Mitteln gestaltet sind, noch verschiedene Vorteile auf: Ein erster Vorteil kann darin gesehen werden, dass das erfindungsgemässe Verfahren keinesfalls nur auf Türen und Aufzüge beschränkt ist, sondern gleichzeitig auch andere, den Zutritt regulierende Einrichtungen wie Fahrtreppen, Drehkreuze usw. zu steuern vermag. Eine dermassen gestaltete Zutrittskontrolle kann so in einfacher Weise beliebig redundant und damit beliebig sicher ausgebildet werden. Zusätzliche Vorteile ergeben sich aus dem Umstande, dass mit dem Erfindungsgegenstand eine rasche und vorzeitige Befehlsgabe möglich ist. Dies führt bei Aufzugsanlagen zu verkürzten Wartezeiten und damit zu einer Erhöhung der Förderleistung und einer allgemeinen Verkehrserleichterung. Ferner wurde festgestellt, dass das µ-Prozessor gestützte Verfahren eine individuelle Erfassung und Überwachung des privaten d.h. nicht-öffentlichen Personenverkehrs ermöglicht und dadurch jede Zutrittskontrolle sicherer macht. Vorzugsweise wird der zutrittsberechtigte Personenverkehr individuell nach Zutrittsort, Zutrittszeit, Zutrittsdauer oder anderen Verkehrsparametern erfasst und analysiert und daraus laufend ein umfassendes Bild des Sicherheitsgeschehens gewonnen. Weiter hat sich als vorteilhaft erwiesen, dass das Verfahren programmierbar und dadurch in seiner Anwendung sehr flexibel ist. Änderungen in der Zutrittsberechtigung bezüglich Personen, Gebäuden, Zutrittszeiten usw. können so jederzeit rasch einprogrammiert werden. Auch hat sich gezeigt, dass die dem erfindungsgemässen Verfahren zugrunde liegende Einrichtung an beliebigen Orten eingebaut und z.B. über eine Datensammelschiene in bestehende Steuerungen integriert werden kann. Verfahren und Einrichtung eignen sich demnach vorzüglich, um herkömmliche Steuerungen auf drahtlose Fernbedienung nachzurüsten und sie dadurch nachträglich in ihrem Betriebsverhalten gesichert und in der Bedienung komfortabel zu gestalten.In addition, methods and equipment designed with these means have various advantages: A first advantage can be seen in the fact that the method according to the invention is by no means limited to doors and elevators, but at the same time also other means regulating access, such as Can control escalators, turnstiles, etc. An access control designed in this way can thus be designed in a simple manner as redundantly and thus as securely as desired. Additional advantages result from the fact that the subject of the invention enables a quick and premature command. In the case of elevator systems, this leads to shorter waiting times and thus to an increase in the conveying capacity and a general easing of traffic. It was also found that the µ-processor-based method enables individual recording and monitoring of private, ie non-public, passenger traffic, thereby making every access control more secure. The authorized passenger traffic is preferably recorded and analyzed individually according to the access location, access time, access duration or other traffic parameters, and a comprehensive picture of the security situation is continuously obtained therefrom. It has also proven to be advantageous that the method is programmable and therefore very flexible in its application. Changes in access authorization with regard to people, buildings, access times, etc. can be programmed quickly at any time. It has also been shown that the device on which the method according to the invention is based can be installed at any location and can be integrated into existing controls, for example via a data bus. The method and device are therefore ideally suited to converting conventional controls to wireless ones To retrofit the remote control and thereby ensure its operational behavior and make it easy to use.

Die Fig. 1 zeigt einen, als Teil eines grösseren Gebäudes ausgebildeten Sicherheitstrakt 1 mit einer Sicherheitstür 5 im Haupteingang 6, einer Aufzugsgruppe 4 mit den Aufzügen 4a, 4b und 4c, einem Sicherheitslabor 2 sowie zusätzlichen, nicht weiter dargestellten Räumlichkeiten in höheren Stockwerken. Die Aufzugsgruppe 4 führt vom Lobby 7 mit den Zugängen 11, 12 in die oberen Stockwerke und vom ersten Stockwerk 3 weiter über die Labortüre 13 mit Labortürschloss 14 in das Sicherheitslabor 2. Im Lobby 7 befinden sich zwei Benutzer 15, 16 des erfindungsgemässen Verfahrens. Sie sind im Begriffe, den mittleren Aufzug 4b zu besteigen und tragen beide je eine portable Sende-/Empfangseinheit [S/E-Einheit] 17 bzw. 18 auf sich, zur gesicherten und/oder komfortablen Bedienung der Sicherheitstüre 5, der Aufzugsgruppe 4, der Labortüre 13 oder zusätzlicher, nicht weiter dargestellter, über eine Steuerung betätigbarer technischer Einrichtungen. Hierzu ist jeder der zu bedienenden technischen Einrichtungen mindestens eine mit den portablen S/E-Einheiten 17, 18 zusammenwirkende stationäre Sende-/Empfangseinheit [S/E-Einheit] zugeordnet, nämlich der Sicherheitstüre 5 die stationäre S/E-Einheit 21 der Aufzugsgruppe 4 die stationären S/E-Einheiten 22a, 22b, 22c, 22d und der Labortüre 13 die stationäre S/E-Einheit 23.1 does not show a security wing 1, which is designed as part of a larger building, with a security door 5 in the main entrance 6, an elevator group 4 with the elevators 4a, 4b and 4c, a security laboratory 2 and additional ones premises shown on higher floors. The elevator group 4 leads from the lobby 7 with the accesses 11, 12 to the upper floors and from the first floor 3 via the laboratory door 13 with the laboratory door lock 14 to the security laboratory 2. In the lobby 7 there are two users 15, 16 of the method according to the invention. You are about to climb the middle elevator 4b and each carry a portable transmitter / receiver unit [S / E unit] 17 or 18, for secure and / or convenient operation of the security door 5, the elevator group 4, the laboratory door 13 or additional technical devices, not shown, which can be actuated by a control. For this purpose, each of the technical devices to be operated is assigned at least one stationary transmitting / receiving unit [S / E unit] which interacts with the portable S / E units 17, 18, namely the stationary S / E unit 21 of the elevator group 5 to the security door 5 4 the stationary S / E units 22a, 22b, 22c, 22d and the laboratory door 13 the stationary S / E unit 23.

Im Anwendungsbeispiel der Fig. 2 ist die Geräteanordnung und deren grundlegende Wirkungsweise der für das erfindungsgemässe Verfahren vorgesehenen Einrichtung bei einer Haltestelle 26 der Aufzugsgruppe 4 dargestellt, wo Bedienungsanforderungen vom Stockwerk aus als Steuerbefehle in die Aufzugsgruppensteuerung eingegeben werden. In der Gebäudewand 27 neben den Aufzugstüren 28 befinden sich links und rechts vom Eingang 29 zu der Kabine 30 je eine stationäre S/E-Einheit 31. Die portable S/E-Einheit 32 wird vom Benutzer 15, 16 auf sich getragen. Die Sende-/Empfangsbereiche der einzelnen S/E-Einheiten 31, 32 sind durch Ellipsen 33, 34 dargestellt. Analoge Gerätekonfigurationen, allerdings nur mit je einer stationären S/E-Einheit, sind auch für die Befehlseingaben zur Steuerung der Sicherheitstüre 5 und der Labortüre 13 vorgesehen. Selbstverständlich gelten auch für diese S/E-Einheiten in etwa die gleichen, den Ellipsen 33, 34 entsprechenden Wirkbereiche.2 shows the device arrangement and its basic mode of operation of the device provided for the method according to the invention at a stop 26 in elevator group 4, where operating requests are entered from the floor as control commands into the elevator group controller. In the building wall 27 next to the elevator doors 28 there is a stationary S / E unit 31 on the left and right of the entrance 29 to the car 30. The portable S / E unit 32 is carried by the user 15, 16. The transmission / reception areas of the individual S / E units 31, 32 are represented by ellipses 33, 34. Analog device configurations, but only with one stationary S / E unit each, are also provided for the command inputs for controlling the security door 5 and the laboratory door 13. Of course, the same effective ranges corresponding to the ellipses 33, 34 also apply to these S / E units.

In Fig. 3 sind mit 17, 18 wieder die von den beiden Benutzern 15, 16 auf sich getragenen portablen S/E-Einheiten und mit 21; 22a, 22b, 22c, 22d; 23 die der Sicherheitstüre 5 bzw. der Aufzugsgruppe 4 bzw. der Labortüre 13 zugeordneten stationären S/E-Einheiten bezeichnet. Aus Gründen, die später erläutert werden und vornehmlich im Bedienungskomfort liegen, sind der Aufzugsgruppe 4 nicht bloss eine, sondern vier örtlich verteilte stationäre S/E-Einheiten 22a, 22b, 22c, 22d zugeordnet. Jede portable S/E-Einheit 17, 18 steht mit jeder der stationären S/E-Einheiten 21; 22a, 22b, 22c, 22d; 23 bilateral und drahtlos in Verbindung, im Rahmen der durch ihre gegenseitige örtliche Lage gegebenen Zuordnung der Wirkbereiche gemäss den Ellipsen 33, 34 in Fig. 2. Die stationären S/E-Einheiten 21, 22a, 22b, 22c, 22d und 23 übertragen die empfangenen Steuersignale (SS₁....SSn ) auf die Steuerung 40 des Antriebes 41 für das Sicherheitstürschloss 42, bzw. auf die Steuerung 43 für die Antriebe 44 der Aufzugsgruppe 4 bzw. auf die Steuerung 45 des Antriebes 46 für das Labortürschloss 47 und empfangen in umgekehrter Richtung als Signalisierung die entsprechenden Rückmeldesignale RM₁....RMn zur Weitergabe an die portablen S/E-Einheiten 17, 18.In Fig. 3 with 17, 18 are again the portable S / E units carried by the two users 15, 16 and with 21; 22a, 22b, 22c, 22d; 23 denotes the stationary S / E units assigned to the security door 5 or the elevator group 4 or the laboratory door 13. For reasons that will be explained later and primarily in terms of ease of use, elevator group 4 is assigned not only one but four locally distributed stationary S / E units 22a, 22b, 22c, 22d. Each portable S / E unit 17, 18 stands with each of the stationary S / E units 21; 22a, 22b, 22c, 22d; 23 bilaterally and wirelessly in connection, within the scope of the assignment of the effective ranges given by their mutual local position according to the ellipses 33, 34 in FIG. 2. The stationary S / E units 21, 22a, 22b, 22c, 22d and 23 transmit the received control signals (SS₁ .... SS n ) on the controller 40 of the drive 41 for the security door lock 42, or on the controller 43 for the drives 44 of the elevator group 4 or on the controller 45 of the drive 46 for the laboratory door lock 47 and receive in the opposite direction as signaling the corresponding feedback signals RM₁ .... RM n for transmission to the portable S / E units 17, 18th

Die Fig. 4 zeigt den funktionellen Aufbau der portablen und der stationären S/E-Einheiten am Beispiel der Befehlseingabe in die Aufzugsgruppe 4 gemäss den Figuren 1 und 3. Dabei werden Steuerbefehle von der portablen S/E-Einheit 17 über die stationäre S/E-Einheit 22a zur Aufzugsgruppensteuerung 43 und Signalisierungen in umgekehrter Richtung übertragen. Je nach der Häufigkeit ihres Auftretens werden die Steuerbefehle auf verschiedene Arten der portablen S/E-Einheit 17 zur Verfügung gestellt: selten auftretende Steuerbefehle SSB sowie öfters auftretende Steuerbefehle ÖSB werden über die Zehnertastatur Z₀....Z₉ bzw. mittels Fixtasten F₁....Fn an der portablen S/E-Einheit 17 eingegeben. Dagegen sind sehr oft auftretende Steuerbefehle OSB im Speicher 59 des µ-Prozessors 51 permanent abgespeichert. Die Zuordnung eines öfters auftretenden Steuerbefehles ÖSB zu einer Fixtaste F₁....Fn erfolgt durch deren gleichzeitiges Betätigen mit der Memorytaste 52. Sowohl die eingegebenen, wie die permanent abgespeicherten Steuerbefehle SSB, ÖSB bzw. OSB erfahren im µ-Prozessor 51 eine als Verfahrensmerkmal definierte und später erläuterte Umformung zu Steuersignalen SS₁....SSn welche vom Sender 53 entsprechend der Stellung des Betriebsartenwahlschalters 54 in den beiden Betriebsarten "automatisch, permanent" oder "manuell, auf Knopfdruck" ausgesendet werden. Der Sender 53 dient zur Übermittlung der Daten. Es handelt sich dabei um einen Sender der in einem erlaubten Frequenzband arbeitet und keine Störung von Radio-, Fernseh- oder Datenübertragungskanälen hervorruft. Andererseits gelangen Rückmeldesignale RM₁....RMn von der stationären S/E-Einheit 22a über den Empfänger 56 in den µ-Prozessor 51, um von dort, nach entsprechender Umformung, in der Anzeige 57 zur Darstellung gebracht zu werden. Die Anzeige dient der Darstellung der Zustände der portablen S/E-Einheit. Solange auf das Sendesignal keine Antwort registriert wird bleibt die Anzeige dunkel. Wird mittels des Empfängers 56 ein Antwortsignal erkannt, erfolgt eine Quittierung und die Anzeige wird eingeschaltet. Die Anzeige wird ausgeschaltet, wenn alle Funktionen erledigt sind. Die Betätigung der Anzeige erfolgt mittels des µ-Prozessors 51. Normalerweise dient eine eingebaute Knopfbatterie als Speisung 58 des Gerätes. Wird das Gerät offen getragen, trägt eine integrierte Solarzelle zur Speisung der Elektronik bei. In der stationären S/E-Einheit 22a leitet der Empfänger 61 die empfangenen Steuersignale SS₁....SSn an den µ-Prozessor 62 weiter, wo sie, gemäss einem weiteren Verfahrensmerkmal ausgewertet und über die als serieller Bus ausgebildete Schnittstelle 63 der Aufzugsgruppensteuerung 43 zugeführt werden. In umgekehrter Richtung gelangen Signalisierungen von der Aufzugsgruppensteuerung 43 in den µ-Prozessor 62, wo sie umgeformt werden, um die stationäre S/E-Einheit 22a über den Sender 64 als Rückmeldesignale RM₁....RMn zu verlassen. Jede stationäre S/E-Einheit wird über eine getrennte Speisung 65 mit Strom versorgt.FIG. 4 shows the functional structure of the portable and the stationary S / E units using the example of the command input into the elevator group 4 according to FIGS. 1 and 3. Control commands from the portable S / E unit 17 via the stationary S / E E unit 22a for elevator group control 43 and signaling transmitted in the reverse direction. Depending on the frequency of their occurrence, the control commands are made available in various ways by the portable S / E unit 17: control commands SSB which occur infrequently and control commands which occur frequently are used via the numeric keypad Z₀ .... Z₉ or by means of fixed keys F₁ .. ..F n entered on the portable S / E unit 17. In contrast, very frequently occurring control commands OSB are permanently stored in the memory 59 of the μ-processor 51. The assignment of a Frequently occurring control commands ÖSB to a fixed key F₁ .... F n takes place by their simultaneous actuation with the memory key 52. Both the entered and the permanently stored control commands SSB, ÖSB or OSB experience in the µ-processor 51 a defined as a process feature and later explained transformation to control signals SS₁ .... SS n which are transmitted by the transmitter 53 according to the position of the mode selector switch 54 in the two modes "automatic, permanent" or "manual, at the push of a button". The transmitter 53 is used to transmit the data. It is a transmitter that works in an allowed frequency band and does not interfere with radio, television or data transmission channels. On the other hand, feedback signals RM 1 ... RM n arrive from the stationary S / E unit 22 a via the receiver 56 in the μ-processor 51, in order to be displayed there, after corresponding conversion, in the display 57. The display shows the status of the portable S / E unit. The display remains dark as long as no response is registered to the transmission signal. If a response signal is recognized by means of the receiver 56, an acknowledgment takes place and the display is switched on. The display is switched off when all functions are done. The display is actuated by means of the μ-processor 51. A built-in button battery normally serves as the supply 58 for the device. If the device is worn open, an integrated solar cell helps feed the electronics. In the stationary S / E unit 22a, the receiver 61 forwards the received control signals SS₁ .... SS n to the μ-processor 62, where they are evaluated according to a further feature of the method and via the interface 63 of the elevator group controller designed as a serial bus 43 are supplied. In the opposite direction, signals from the elevator group controller 43 enter the μ-processor 62, where they are reshaped to leave the stationary S / E unit 22a via the transmitter 64 as feedback signals RM₁ .... RM n . Each stationary S / E unit is powered by a separate supply 65 powered.

Zur Erläuterung der Funktionsweise des Steuerungsverfahrens sei auf die Figuren 1 bis 4 hingewiesen und vor den Verfahrensschritten ausgegangen, die der Erfindung zugrunde liegen. Dabei wird das erfindungsgemässe Verfahren in seinen beiden Hauptanwendungen, nämlich zur gesicherten Eingabe von Steuerbefehlen und zur Verbesserung des Bedienungskomforts zur Darstellung gebracht. Im ersten Falle handelt es sich um eine Zutrittskontrolle, bei welcher der Zutritt zum nicht-öffentlichen Sicherheitslabor 2 für den Benutzer 16 zweifach redundant gesichert ist, nämlich durch die Sicherheitstüre 5, durch die Aufzugsgruppe 4, sowie durch die Labortüre 13. Im zweiten Falle hat der Benutzer 15 überall freien Zutritt, so dass für ihn keine sicherheitstechnische Anwendung vorliegt, sondern ihm die Neuerung lediglich zur Verbesserung des Bedienungskomforts dient. Bei der sicherheitstechnischen Anwendung, d.h. der Zutrittskontrolle zum Sicherheitslabor 2 geht es vorerst darum, vom Haupteingang 6 in das Lobby 7 des Sicherheitstraktes 1 zu gelangen, wozu die Sicherheitstüre 5 bedient werden muss. Da diese Funktion täglich angewendet wird, handelt es sich dabei um einen öfters auftretenden Steuerbefehl ÖSB der zweckmässigerweise der Fixtaste F₁ fest zugeordnet ist. Wenn sich der Benutzer 16 im Haupteingang 7 befindet, gibt er mittels dieser Fixtaste F₁ den Öffnungsbefehl für die Sicherheitstüre 5 an seiner portablen S/E-Einheit 18 ein und sendet ihn z.B. in der Betriebsart "manuell, auf Knopfdruck" mit der Sendetaste 55 aus. Die entsprechende stationäre S/E-Einheit 21 empfängt den ausgesendeten Steuerbefehl und gibt bei positiver, am Beispiel der Aufzugsgruppe 4 näher erläuterten Sicherheitsanalyse, die Sicherheitstüre zum Öffnen frei. Hat der Benutzer 16 das Lobby 7 erreicht, sendet er mit der verbergbaren, drahtlosen, portablen S/E-Einheit 18 einen Stockwerkruf zur stationären Sende-/Empfangseinheit 22a. Der Benutzer 16 trägt die portable S/E-Einheit 18 in der Hand oder in einer Kleidertasche, wobei der Stockwerkruf z.B. über die Fixtaste F₂ eingegeben und über die Sendetaste 55 ausgesendet wird. Gemäss Fig. 4 besitzt die portable S/E-Einheit 18 einen Betriebsartenwahlschalter 54, der die Umschaltung zwischen zwei Betriebsarten "automatisch, permanent" und "manuell, auf Knopfdruck" ermöglicht: In der Stellung "manuell, auf Knopfdruck" wird bei Betätigung der Sendetaste 55 über den Sender 53 ein Steuersignal SS₁....SSn mit folgendem Inhalt ausgesendet: Ein Sicherheitscode für die Identifikation des Benutzers. Dieser Sicherheitscode besteht aus zwei Teilen: dem Gebäudeteil (High Byte) und dem Benutzerteil (Low Byte). Mit dem Gebäudeteil wird die Identifikation der einzelnen Gebäude oder von Gebäudeteilen ermöglicht. Der Benutzerteil beinhaltet Daten des Benutzers. Funktionscode für die Steuerung beinhaltet auch die Information ob es sich um eine Standartfunktion oder um eine nachfolgende Spezialfunktion handelt.To explain the mode of operation of the control method, reference is made to FIGS. 1 to 4 and the method steps on which the invention is based are assumed. The method according to the invention is presented in its two main applications, namely for the secure input of control commands and for improving the ease of use. In the first case, it is an access control in which access to the non-public security laboratory 2 is secured redundantly for the user 16, namely through the security door 5, through the elevator group 4, and through the laboratory door 13. In the second case the user 15 has free access everywhere, so that there is no safety-related application for him, but the innovation only serves to improve the ease of use. In the security application, ie the access control to the security laboratory 2, the first step is to get from the main entrance 6 into the lobby 7 of the security wing 1, for which the security door 5 has to be operated. Since this function is used daily, it is a frequently occurring control command ÖSB which is appropriately assigned to the fixed key F₁. If the user 16 is in the main entrance 7, he gives the opening command for the security door 5 to his portable S / E unit 18 by means of this fixed key F 1 and sends it, for example, in the operating mode "manually, at the push of a button" with the send key 55 . The corresponding stationary S / E unit 21 receives the transmitted control command and, in the event of a positive security analysis, which is explained in more detail using the example of elevator group 4, releases the security door for opening. When the user 16 has reached the lobby 7, he sends a concealed, wireless, portable S / E unit 18 to a floor call to the stationary transceiver unit 22a. The user 16 carries the portable S / E unit 18 in his hand or in a pocket, the floor call, for example entered via the fixed key F₂ and transmitted via the send key 55. According to FIG. 4, the portable S / E unit 18 has an operating mode selector switch 54 which enables the switching between two operating modes "automatic, permanent" and "manual, at the push of a button": In the "manual, at the push of a button" position, when the Send button 55 on the transmitter 53 a control signal SS₁ .... SS n sent out with the following content: A security code for the identification of the user. This security code consists of two parts: the building part (high byte) and the user part (low byte). With the building part, the identification of the individual building or of building parts is made possible. The user part contains user data. Function code for the control also contains the information whether it is a standard function or a subsequent special function.

In der Stellung "automatisch, permanent" werden dieselben Informationen in Abständen von 200 Millisekunden vom Sender 53 automatisch ausgesendet. Mittels der Zehnertastatur Z₀....Z₉ können bei Aufzügen selten angefahrene Stockwerke angewählt werden. Hierzu ist zuerst der Betriebsartenwahlschalter 54 auf die Stellung "auf Knopfdruck" zu stellen und sodann das gewünschte Stockwerk einzutippen. Bei Betätigung der Sendetaste 55 wird die Information ausgesendet. Öfters angefahrene Stockwerke, die keine Standartstockwerke sind, können über Fixtasten F₁....Fn aktiviert werden. Die Abspeicherung solcher Stockwerke erfolgt über die Kombination mit einer Memorytaste 52. Standartstockwerke sind der Haupthalt (Eingang), die eigene Wohnungstüre, die Etage auf der sich die Wohnung oder das Büro befindet. Jeweils nach dem Aussenden des Steuerungssignales SS₁....SSn schaltet der µ-Prozessor 51 kurze Zeit auf Empfang um. Werden in dieser Zeitdauer Rückmeldesignale RM₁....RMn empfangen, werden diese nachdem sie gefiltert wurden dem µ-Prozessor 51 zur Identifikation und Analyse übermittelt. Im einzelnen ist der µ-Prozessor 51 für folgende Funktionen zuständig: Tastaturhandling, Erkennung der Modewählerstellung, Speicherung und Erkennung der Daten die von der Tastatur kommen, Aufbereitung der Sendeinformation, Periodisches Senden der Information, Umschalten von Sende- auf Empfangsbetrieb, Analyse der empfangenen Meldungen, Führung des Anzeigemodus. Die stationäre S/E-Einheit 22a empfängt das ausgesendete Steuersignal SS₁....SSn und gibt den Stockwerkruf in derselben Weise an die Aufzugsgruppensteuerung 43 weiter, wie wenn er direkt am Stockwerktableau 24 eingegeben worden wäre. Voraussetzung ist natürlich, dass sich die portable S/E-Einheit 18 im Empfangsbereich der stationären S/E-Einheit 22a befindet. Der Sender 64 dient zur Übermittlung der Rückmeldesignale RM₁, RM₂. Es handelt sich dabei um einen Sender der wie der Sender 53 in der portablen S/E-Einheit 17, 18 in einem erlaubten Frequenzband arbeitet und keine Störung von Radio-, Fernseh-oder Datenübertragungskanälen hervorruft. Die stationäre S/E-Einheit 22a ist normalerweise auf Empfang geschaltet. Werden Steuersignale empfangen, werden diese nach entsprechender Aufbereitung an den µ-Prozessor 62 weitergeleitet. Gehören die aufgenommenen Daten zur entsprechenden Anlage, so wird ein Bestätigungssignal RM₁ aufbereitet. Der µ-Prozessor 62 ist für folgende Funktionen zuständig: Aufbereitung der Sendeinformation, Aktivierung des Senders, Umschalten von Empfangs- auf Sendebetrieb, Analyse der empfangenen Meldungen, Erzeugung der notwendigen Befehle für die Aufzugssteuerung. Ist der eingegebene Stockwerkruf z.B. vom Aufzug 4b beantwortet worden, betritt der Benutzer 16 die entsprechende Kabine, um in vorbeschriebener Art und Weise mit seiner portablen S/E-Einheit 18 und einer weiteren, im Kabinentableau 25 integrierten stationären S/E-Einheit 22d einen Kabinenruf nach dem 1. Stockwerk 3 oder eine andere Bedienungsanforderung wie z.B. Nothalt oder stummer Notruf einzugeben. Es sei angenommen, dass ein Kabinenruf nach dem selten verlangten 1. Stockwerk 3 eingegeben werde. Dieser selten auftretende Steuerbefehl wird deshalb durch Betätigen einer oder mehrer Tasten der Zehnertastatur Z₀....Z₉, welche jeweils ein Stockwerk bezeichnen und einzeln oder in Kombination verwendet werden können, eingegeben, über die Sendetaste 55 manuell ausgesendet und durch die stationäre S/E-Einheit 22d in derselben Weise zur Gruppensteuerung 43 weitergeleitet, wie wenn er direkt am Kabinentableau 25 eingegeben worden wäre.In the "automatic, permanent" position, the same information is transmitted automatically by the transmitter 53 at intervals of 200 milliseconds. Using the numeric keypad Z₀ .... Z₉, floors that are rarely used can be selected. To do this, first set the operating mode selector switch 54 to the "at the push of a button" position and then type in the desired floor. When the send button 55 is actuated, the information is sent out. Frequently used floors, which are not standard floors, can be activated with fixed keys F₁ .... F n . Such floors are saved using a combination with a memory key 52. Standard floors are the main stop (entrance), your own apartment door, the floor on which the apartment or office is located. Each time after the transmission of the control signal SS₁ .... SS n , the µ-processor 51 switches to reception for a short time. If feedback signals RM 1 ... RM n are received in this period, they are transmitted to the µ-processor 51 for identification and analysis after they have been filtered. In particular, the µ processor 51 is responsible for the following functions: keyboard handling, detection of the mode selector position, Storage and recognition of the data coming from the keyboard, preparation of the send information, periodic sending of the information, switching from send to receive mode, analysis of the received messages, management of the display mode. The stationary S / E unit 22a receives the transmitted control signal SS₁ .... SS n and forwards the floor call in the same way to the elevator group controller 43 as if it had been entered directly on the floor tableau 24. The prerequisite is of course that the portable S / E unit 18 is in the reception area of the stationary S / E unit 22a. The transmitter 64 is used to transmit the feedback signals RM₁, RM₂. It is a transmitter which, like the transmitter 53 in the portable S / E unit 17, 18, operates in an allowed frequency band and does not cause interference to radio, television or data transmission channels. The stationary S / E unit 22a is normally switched to receive. If control signals are received, they are forwarded to the µ processor 62 after appropriate processing. If the recorded data belongs to the corresponding system, a confirmation signal RM 1 is processed. The µ processor 62 is responsible for the following functions: preparation of the transmission information, activation of the transmitter, switching from reception to transmission operation, analysis of the received messages, generation of the necessary commands for the elevator control. If the floor call entered has been answered, for example, by the elevator 4b, the user 16 enters the corresponding cabin in order to have one with his portable S / E unit 18 and a further stationary S / E unit 22d integrated in the cabin panel 25 in the manner described above Enter the cabin call after the 1st floor 3 or another operating request such as an emergency stop or silent emergency call. It is assumed that a cabin call is entered after the rarely requested 1st floor 3. This rarely occurring control command is therefore activated by pressing one or more keys on the numeric keypad Z₀ .... Z₉, each of which designates a floor and individually or in Combination can be used, entered, transmitted manually via the send button 55 and forwarded to the group control 43 by the stationary S / E unit 22d in the same way as if it had been entered directly on the car panel 25.

Im 1. Stockwerk 3 angekommen hat der Benutzer 16 als letzte Stufe der Zutrittskontrolle zum Sicherheitslabor 2 die Labortüre 13 zu öffnen. Dies kann z.B. in der Betriebsart "manuell, auf Knopfdruck" erfolgen, mittels der Fixtasten F₁....Fn oder über die Zehnertastaten Z₀....Z₉, analog zur vorbeschriebenen Öffnung der Sicherheitstüre 5. In seiner Anwendung zur Verbesserung des Bedienungskomforts und zur Erleichterung des Personenverkehrs ist das erfindungsgemässe Verfahren von Bedeutung, wenn es darum geht, gesteuerte technische Einrichtungen wie Türen, Aufzüge, Fahrtreppen usw. von einer beliebigen Stelle aus in deren näheren Umgebung oder ohne Benützung der Hände zu bedienen. Diese Notwendigkeit ergibt sich bei einem Fahrgast, der behindert ist, oder der etwas trägt (Mutter mit Kind und Einkaufstasche, Geschäfsmann mit Zeitung und Aktenkoffer) wodurch seine Bewegungsfreiheit eingeschränkt oder sogar stark reduziert ist. In dieser Situation stellt die Bedienung der normalen Ruftasten eines Aufzuges eine unangenehme Notwendigkeit dar. Ausgehend von derselben Art von Behinderung stellt sich dasselbe Problem beim Öffnen von Türen. Die Haustüre beziehungsweise die Wohnungstüre lassen sich nur umständlich öffnen. Zur Verdeutlichung dieser Einsatzmöglichkeit sei angenommen, dass im Bürogebäude gemäss Fig. 1 der Benutzer 16 mit Akten 19 vom Lobby 7 in ein Büro in einem höheren Stockwerk gelangen will. Eine als Zielruf ausgebildete Bedienungsanforderung soll also ohne Manipulation in die Steuerung 43 der Aufzugsgruppe 4 eingegeben werden. Hierzu ist der entsprechende Zielruf im Speicher 59 der portablen S/E-Einheit 18 permanent abgespeichert oder an ihr vom Benutzer 16 über die Zehnertastatur Z₀....Z₉ oder die Fixtasten F₁....Fn vorsorglich eingegeben worden und die Betriebsart "selbsttätig, permanent" aktiv. Der Zielruf wird also alle 200 Millisekunden selbsttätig ausgesendet und vor den beiden stationären S/E-Einheiten 22b, 22c zur Steuerung 43 der Aufzugsgruppe 4 übermittelt, wenn sich der Benutzer 16 im entsprechenden Wirkbereich befindet. Dabei wird in der Kabine mit z.B. den geringsten Bedienungskosten, der Stockwerkruf und nach dem Zusteigen des Benutzers 16 auch der entsprechende Kabinenruf generiert, der bereits vorgängig in die Kostenrechnung einfliessen konnte. Die Signalisierung erfolgt auf der Anzeige 57 der entsprechenden portablen S/E-Einheit 18. Dazu gehören z.B. die "Registrierung" (RM₁), sowie die "Aufzugsnummer" (RM₃) d.h. die Darstellung der Nummer jenes Aufzuges 4a, 4b, 4c, dem der entsprechende Zielruf zur Bedienung zugeteilt worden ist. Dem Benutzer 16 wird so mitgeteilt, dass sein Zielruf in der Gruppensteuerung 43 registriert worden ist und insbesondere auch, in welche Kabine er zusteigen muss, um zu seinem Zielstockwerk zu gelangen. Vorzugsweise sind die stationären S/E-Einheiten 22b und 22c so positioniert, dass die Zeit um vor ihnen zu den Aufzugstüren zu gelangen, in etwa der mittleren Wartezeit nach Registrierung eines Stockwerkrufes entspricht. Daraus ergibt sich für den Benutzer im Mittel eine stark reduzierte Wartezeit und dies ohne Einhalten eines vorgegebenen Zeitplanes. Offensichtlich führt dies zu einer Erhöhung der Förderleistung. Nach Betreten der Aufzugskabine erreicht der Benutzer 16 das verlangte Stockwerk, wo in gleicher Weise, d.h. selbsttätig und ohne Manipulation, die Tür zum gewünschten Büro geöffnet wird. Selbstverständlich kann anstatt eines Zielrufes auch ein Stockwerkruf mit nachfolgendem Kabinenruf in der Betriebsart "selbsttätig, permanent" eingegeben werden. Da der Kabinenruf permanent ausgesendet wird, erfolgt seine Eingabe in die Aufzugssteuerung fristgerecht beim Betreten der Aufzugskabine durch den Benutzer. Die Notwendigkeit, das Tastenfeld in Anwesenheit anderer Personen betätigen zu müssen, entfällt somit. Bei der Anwendung in Hotels kann jedem Hotelgast an der Reception eine kreditkartengrosse portable S/E-Einheit 17, 18 ausgehändigt werden, deren Funktionstasten auf die öffentlichen Stockwerke und auf das Stockwerk des Zimmers programmiert sind. Damit wird der Hotelgast von der Lobby zu seinem Zimmer geleitet. In der Wand vor der Zimmertüre ist ein Empfangsgerät eingebaut. Mit einer weiteren Funktionstaste kann die Zimmertüre geöffnet werden. Bei Verlust einer solchen Karte wird lediglich der Zimmeridentifikationscode geändert.Once on the first floor 3, the user 16 has to open the laboratory door 13 as the last step in access control to the security laboratory 2. This can be done, for example, in the operating mode "manually, at the push of a button", using the fixed keys F₁ .... F n or the ten keys Z₀ .... Z₉, analogous to the opening of the security door 5 described above. In its application to improve the ease of use and to facilitate passenger traffic, the method according to the invention is important when it comes to operating controlled technical devices such as doors, elevators, escalators, etc. from any location in their immediate vicinity or without using the hands. This is necessary for a passenger who is disabled or who is carrying something (mother with child and shopping bag, businessman with newspaper and briefcase), which limits or even greatly reduces his freedom of movement. In this situation, the operation of the normal call buttons of an elevator is an unpleasant necessity. Starting from the same type of disability, the same problem arises when opening doors. The front door or apartment door can only be opened with great difficulty. To clarify this possible application, it is assumed that in the office building according to FIG. 1, the user 16 with files 19 wants to get from the lobby 7 to an office on a higher floor. An operating request designed as a destination call should therefore be entered into the controller 43 of the elevator group 4 without manipulation. For this purpose, the corresponding destination call is permanently stored in the memory 59 of the portable S / E unit 18 or, as a precaution, it has been entered by the user 16 via the numeric keypad Z₀ .... Z₉ or the fixed keys F₁ .... F n and the operating mode "automatic, permanent" active. The destination call is therefore sent out automatically every 200 milliseconds and transmitted in front of the two stationary S / E units 22b, 22c to the controller 43 of the elevator group 4 when the user 16 is in the corresponding effective range. In this case, the floor call is generated in the cabin with, for example, the lowest operating costs, and after the user 16 has climbed in, the corresponding cabin call is generated, which could already have been included in the cost calculation beforehand. The signaling takes place on the display 57 of the corresponding portable S / E unit 18. These include, for example, the "registration" (RM₁), and the "elevator number" (RM₃) ie the representation of the number of that elevator 4a, 4b, 4c, the the corresponding destination call has been assigned for operation. The user 16 is informed that his destination call has been registered in the group control 43 and in particular also in which cabin he has to get in to get to his destination floor. The stationary S / E units 22b and 22c are preferably positioned such that the time to get to the elevator doors in front of them corresponds approximately to the mean waiting time after registering a floor call. This results in a greatly reduced waiting time for the user, on average, and this without adhering to a predetermined schedule. Obviously, this leads to an increase in the output. After entering the elevator car, the user 16 reaches the requested floor, where the door to the desired office is opened in the same way, ie automatically and without manipulation. Of course, instead of a destination call, a floor call with subsequent cabin call can also be entered in the "automatic, permanent" operating mode. Since the car call is continuously transmitted, it is entered into the elevator control by the user on time when entering the elevator car. This eliminates the need to operate the keypad in the presence of other people. When used in hotels, every hotel guest can use a credit card-sized portable S / E unit at the reception 17, 18 are handed over, the function keys of which are programmed on the public floors and on the floor of the room. This guides the hotel guest from the lobby to his room. A receiver is built into the wall in front of the room door. The room door can be opened with another function key. If such a card is lost, only the room identification code is changed.

Obgleich die Erfindung vorstehend im Zusammenhang mit der gesicherten und komfortablen Eingabe von Steuerbefehlen bei Aufzugsanlagen und Türen beschrieben ist, kann sie auch allgemein bei gesteuerten technischen Einrichtungen angewandt werden. Solche Anwendungsbereiche dürften für den Fachmann anhand der vorstehenden Beschreibung offensichtlich sein.Although the invention has been described above in connection with the secure and convenient input of control commands in elevator systems and doors, it can also be applied in general to controlled technical devices. Such areas of application should be obvious to those skilled in the art from the above description.

Claims (7)

1. Method for the secured and convenient entry of control commands, in particular in lift installations, in which method control commands are entered at a portable wireless transmitter and emitted by this as coded control signals which are received by a stationary receiver and after decoding led to a control, wherein the registration at the control and the execution of these control commands is signalled, characterised by the following steps:
a) control commands are allocated in accordance with their frequency to one of the following three groups:
- rarely occurring control commands (SSB),
- more frequently occurring control commands (ÖSB) and
- very frequently occurring control commands (OSB).
b) Rarely occurring control commands (SSB) as well as more frequently occurring control commands (ÖSB) are entered individually at at least one portable transmitter-receiver unit (17, 18) by means of a decade keyboard (Z₀ to Zg) or by means of fixed keys (F₁ to Fn), whilst very frequently occurring control commands (OSB) are stored permanently in at least one portable transmitter-receiver unit (17, 18).
c) Entered or permanently stored control commands (SSB, ÖSB or OSB) are reshaped in the corresponding portable transmitter-receiver unit (17, 18) into control signals (SS₁ to SSn) each consisting respectively of a security part (ST) and a function part (FT) and emitted selectably in the modes of operation "manually by pushbutton" or "automatically permanent".
d) After each emission of a control signal (SS₁ to SSn), the corresponding portable transmitter-receiver unit (17, 18) automatically switches to reception for a constant time duration (Δt).
e) A control signal (SS₁ to SSn) emitted by at least one portable transmitter-receiver unit (17, 18) is received by at least one stationary transmitter-receiver unit (21; 22a, 22b, 22c, 22d; 23) and there subjected to a security analysis as well as to a function analysis.
f) In the case of a negative result of the security analysis, the received control command (SSB, ÖSB, OSB) is ignored by the stationary transmitter-receiver unit (21; 22a, 22b, 22c, 22d; 23).
g) In the case of a positive result of the security analysis, the received control command (SSB, ÖSB, OSB) is entered into a control (40, 43, 45) and the stationary transmitter-receiver unit (21; 22a, 22b, 22c, 22d; 23) emits a first reporting-back signal (RM₁), which signals the registration of the control command (SSB, ÖSB, OSB) on the indicator (57) of the corresponding portable transmitter-receiver unit (17, 18) and thereby blocks the same for a further command entry.
h) After execution of a control command, the stationary transmitter-receiver unit (21; 22a, 22b, 22c, 22d; 23) emits a second reporting-back signal (RM₂), which cancels the indication on the corresponding portable transmitter-receiver unit (17, 18) and thereby frees the same for the next command entry.
2. Method according to claim 1, characterised thereby, that the allocation of more frequently occurring control commands (ÖSB) to a respective fixed key (F₁ to Fn) takes place through its actuation simultaneously with that of a memory key (52).
3. Method according to claim 1, characterised thereby, that the control signals (SS₁ to SSn) and the return report signals (RM₁ to RM₂) are transmitted wirelessly in the form of digitally coded infrared signals between at least one portable transmitter-receiver unit (17, 18) and at least one stationary transmitter-receiver unit (21; 22a, 22b, 22c, 22d; 23).
