Der Informationsgeber 5 hat die Form beispielsweise einer Kreditkarte, einer Armbanduhr, eines Schlüsselanhängers, eines Knopfes oder eines Siegelringes und kann als aktives Element mit einem Sender, Empfänger, Speicher und Batterie oder als passives, über ein elektromagnetisches Feld gespeistes Element ausgeführt sein. Der Informationsgeber 5 ist ausserhalb des Aufzugsbereiches ruhend und wird über ein von mindestens einer Erkennungsvorrichtung 6 ausgestrahltes elektromagnetisches Feld aufgeweckt. Die Erkennungsvorrichtung 6 kann wie in Fig. 1 gezeigt beispielsweise in der Aufzugskabine 1 und/oder auf dem Stockwerk angeordnet sein. Bei auf dem Stockwerk angeordneter Erkennungsvorrichtung 6 erfolgt die Identifikation vor dem Betreten bzw. Beladen der Aufzugskabine 1.The elevator user 2 carries one for identification Informers 5 with you. Even items like for example shopping carts, luggage trolleys, hospital beds, Containers, etc. can be used with an information provider be equipped. The information provider 5 has the form for example a credit card, a wristwatch, one Keychain, a button or a signet ring and can be used as an active element with a transmitter, receiver, Storage and battery or as passive, via a element powered by an electromagnetic field his. The information provider 5 is outside the Elevator area is dormant and is accessed by at least one a detection device 6 broadcast electromagnetic field woken up. The Detection device 6 can be as shown in FIG. 1 for example in the elevator car 1 and / or on the Floor to be arranged. On the floor arranged detection device 6 takes place Identification before entering or loading the Elevator car 1.

Vor dem Schliessen der Kabinentür wird das identifizierte Gewicht der Aufzugsbenutzer und/oder Gegenstände an einen Vergleicher 8 weitergeleitet, der das von der Lastmessung 4 erfasste Gewicht in der Aufzugskabine 1 mit dem identifizierten Gewicht vergleicht. Ist das Gewicht in der Aufzugskabine 1 um ein bestimmtes Mass grösser als das identifizierte Gewicht, erzeugt der Vergleicher 8 kein Freigabesignal FGS. Die Aufzugskabine 1 bleibt stehen, wobei eine entsprechende optische und/oder akustische Meldung in bzw. vor der Aufzugskabine 1 erzeugt wird. Stimmt das gemessene Gewicht mit dem identifizierten Gewicht überein, wird das Freigabesignal FGS an die Aufzugssteuerung weitergeleitet, die die Aufzugskabine 1 absendet.The identified one is closed before the cabin door is closed Weight of the elevator users and / or objects on one Comparator 8 forwarded by the load measurement 4th detected weight in the elevator car 1 with the compares the identified weight. Is the weight in the Elevator car 1 larger than that by a certain amount identified weight, the comparator 8 produces no Release signal FGS.

Is the measured weight correct with the identified one Weight corresponds, the release signal FGS to the Elevator control forwarded to the elevator car 1 dispatches.

Fig 2. zeigt eine weitere Variante zur Erfassung von Merkmalen des Aufzugsbenutzers 2 mittels elektromagnetischer Wellen. Anstelle der in Fig. 1 gezeigten Lastmesseinrichtung 4 kann ein Schwingkreis bestehend aus einer Induktivität L und eines Kondensators C verwendet werden. Die Resonanzfrequenz wird mittels einer Messeinrichtung 9 gemessen. Der Aufzugsbenutzer 2 beeinflusst die Dielektrizitätskonstante des Kondensators C, wodurch die Kapazität des Kondensators C verändert wird. Das LC-Verhältnis bestimmt die Resonanzfrequenz des Schwingkreises. Je nach Körpermasse des Aufzugsbenutzers wird der Schwingkreis verstimmt. Die Messeinrichtung 9 misst die sich aufgrund der Körpermasse verändernde Resonanzfrequenz, erzeugt ein entsprechendes Massesignal und leitet dieses an den Vergleicher 8 weiter. Stimmt die gemessene Masse mit der identifizierten Masse überein, wird das Freigabesignal FGS an die Aufzugssteuerung weitergeleitet, die die Aufzugskabine 1 absendet.2 shows a further variant for the detection of Features of the elevator user 2 by means of electromagnetic waves.

The resonance frequency is determined by means of a Measuring device 9 measured. The elevator user 2 affects the dielectric constant of the capacitor C, which changes the capacitance of the capacitor C. The LC ratio determines the resonance frequency of the Resonant circuit. Depending on the body mass of the elevator user the resonant circuit is detuned. The measuring device 9 measures the changing due to body mass Resonance frequency, generates a corresponding ground signal and forwards this to the comparator 8. Is that true measured mass matches the identified mass the release signal FGS to the elevator control forwarded, which sends the elevator car 1.

Fig 3. zeigt eine weitere Variante zur Erfassung der für den Transport vorgesehenen Aufzugsbenutzer 2 mittels Druckwellen, wobei das Prinzip des Echolotes angewendet wird. Ein Sender 10 durchstrahlt die Aufzugskabine 1 mit Druckwellen DW. Ein Empfänger 11 erfasst ein Abbild der Aufzugsbenutzer 2 in der Aufzugskabine 1 aufgrund der absorbierten bzw. der reflektierten Wellen RW und leitet das Abbild an den Vergleicher 8 weiter. Stimmt das gemessene Abbild mit dem identifizierten Abbild überein, wird das Freigabesignal FGS an die Aufzugssteuerung weitergeleitet, die die Aufzugskabine 1 absendet.Fig. 3 shows a further variant for recording the for the elevator user 2 provided for transportation Pressure waves, applying the principle of the sounder becomes. A transmitter 10 also radiates through the elevator car 1 Pressure waves DW.
