Mit derartigen berührungslosen elektronischen Zugangskontrollsystemen können Transponder, insbesondere in Kunststoff eingelassene Transponderkarten an Transponderleseeinheiten vorbeigeführt werden, wobei die Transponder induktiv oder auf andere Weise ausgelesen werden und die Transponderleseeinheit daraufhin ein Signal erzeugt, das an eine Türöffnereinheit bzw. Türschließeinheit weitergegeben wird.With such contactless electronic access control systems can transponders, especially in plastic embedded transponder cards on transponder reading units are passed by, the transponders being inductive or read out in another way and the Transponder reader then generates a signal that passed on to a door opener unit or door closing unit becomes.

Es hat sich nun gezeigt, daß derartige Zugangskontrollsysteme nicht in explosionsgefährdeten Bereichen betrieben werden können.It has now been shown that such access control systems not operated in potentially explosive areas can be.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Zugangskontrollsystem der eingangs genannten Art zu schaffen, das auch in explosionsgefährdeten Bereichen betrieben werden kann. The invention is therefore based on the object of an access control system of the type mentioned at the beginning, which is also operated in potentially explosive areas can be.

Die Lösung dieser Aufgabe erfolgt mit einem Zugangskontrollsystem mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.This task is solved with an access control system with the features of claim 1. Advantageous Further developments of the invention are in the subclaims described.

Nach dem Grundgedanken der Erfindung wird ein berührungsloses elektronisches Zugangskontrollsystem mit einer Transponderleseeinheit so weiterentwickelt, daß das Zugangskontrollsystem zur Verwendung in explosionsgefährdeten Bereichen ausgelegt ist, wobei die Elemente des Zugangskontollsystems, die zur Verwendung innerhalb des explosionsgefährdeten Bereichs vorgesehen sind, mit einer druckfesten Umhüllung gekapselt sind. Auf diese Weise ist es erfindungsgemäß möglich, elektronische Zugangskontrollsysteme grundsätzlich bekannter Bauart in explosionsgefährdeten Bereichen einzusetzen. Mit der Erfindung können grundsätzlich nahezu alle bekannten Zugangskontrollsysteme, insbesondere solche, die induktiv oder kapazitiv Signale empfangen, oder auf der Übertragung optischer Signale oder der Übertragung von Ultraschallsignalen beruhen, verwendet werden.According to the basic idea of the invention, a non-contact electronic access control system with one Transponder reader developed so that the access control system for use in potentially explosive atmospheres Areas, whereby the elements of the access control system, for use within the potentially explosive atmosphere Are provided with a range flameproof enclosure are encapsulated. That way According to the invention, it is possible to use electronic access control systems basically known design in potentially explosive atmospheres Areas. With the invention basically all known access control systems, especially those that are inductive or capacitive Receive signals, or optical on the transmission Signals or the transmission of ultrasound signals are used.

Die Umhüllung kann dabei in einer bevorzugten Ausgestaltung beispielsweise als Gehäuse oder als Vergußmasse ausgebildet sein, mit denen die risikoträchtigen Elemente vergossen sind. Dies sind insbesondere die Elemente, die elektronische, elektrische oder mechanische Komponenten aufweisen, die sich übermäßig erwärmen können oder bei denen eine Funkenbildung entstehen kann. Hierzu gehören insbesondere die Transponderleseeinheit und eine Türöffnereinheit bzw. eine Türschließeinheit. Auch andere Komponenten des Zugangskontrollsystems, wie beispielsweise eine Türstatusmeldeeinheit oder eine Türsteuereinheit müssen entweder außerhalb des explosionsgefährdeten Bereiches angeordnet werden oder mit einer erfindungsgemäßen Umhüllung versehen werden. Günstigerweise ist die Umhüllung dabei gasdicht und druckfest. Dadurch wird erreicht, daß Bauteile des Zugangskontrollsystems, bei denen möglicherweise Funken entstehen können, in einem Gehäuse angeordnet sind und nicht mit einem möglicherweise explosiven Umgebungsgas in Berührung kommen können.In a preferred embodiment, the covering can for example, as a housing or as a potting compound be with which the risky elements are shed. In particular, these are the elements that electronic, electrical or mechanical components have that can heat excessively or at which can create sparks. This includes in particular the transponder reading unit and a door opener unit or a door locking unit. Other components too the access control system, such as a door status reporting unit or a door control unit must either be outside the hazardous area can be arranged or with an inventive Be wrapped.

Durch diese Anordnung wird erreicht, daß die Signale noch ausreichend stark ausgesandt werden und das Antwortsignal des Transponders in dem Gehäuse empfangen werden kann. Entsprechendes gilt für Leseeinheiten in anderen Zugangskontrollsystemen, beispielsweise für einen Ultraschallempfänger oder eine kapazitive Leseeinheit. In einer Weiterbildung der Erfindung ist die Leseeinheit, insbesondere die Induktionsspule, in ihrer Form dem Bereich aus Nichtmetall angepaßt, so daß die von der Leseeinheit umschlossene Fläche möglichst groß gestaltet wird. Besonders vorteilhaft ist es, den Bereich aus Nichtmetall aus einer runden Glasscheibe auszubilden, wobei die Leseeinheit, insbesondere die Induktionsspule, kreisförmig ausgebildet und an der Glasscheibe verklebt ist. Auf diese Weise ist die Leseeinheit so nah wie möglich an der nichtmetallischen Fläche befestigt, so daß die von der Leseeinheit erzeugten Felder nur eine vergleichsweise geringe Abschwächung erfahren. Das übrige Gehäuse besteht aus einem für die druckfeste Kapselung geeigneten Material, insbesondere Metall, günstigerweise aus Aluminium, so daß die kreisförmige Spule, die in ihrem Durchmesser dem Durchmesser der runden Glasscheibe entspricht, besonders gut geeignet ist, Signale abzugeben und zu empfangen.Furthermore, the transponder reading unit is preferably an induction coil is provided which is directly connected to the area of non-metal is arranged.

Particularly advantageous is to make the area out of a nonmetal round glass pane, the reading unit, in particular the induction coil, circular and is glued to the glass pane. That way the reading unit as close as possible to the non-metallic Surface attached so that the reading unit generated fields only a comparatively small attenuation Experienced. The rest of the housing consists of a material suitable for pressure-resistant encapsulation, in particular Metal, conveniently made of aluminum, so that circular coil, the diameter of which is the diameter corresponds to the round glass pane, particularly well is suitable for emitting and receiving signals.

Die Transponderleseeinheit weist eine Platine auf, wobei in dem Gehäuse günstigerweise eine Platinenhalterung vorgesehen ist, auf der die Platine so angeordnet ist, daß ein elektrischer Kontakt der Platine nahe an der Leseeinheit, insbesondere der Induktionsspule, vorgesehen ist. Dadurch wird die Montage erleichtert und die notwendige Leitungsstrecke verkürzt. Die Platinenhalterung ist dabei günstigerweise aus drei Platten zusammengesetzt, die so zusammengefügt sind, daß sie im Querschnitt ein rechtwinkliges Dreieck bilden, wobei die Platine auf der Hypothenuse angeordnet ist. Durch diese Ausbildung wird die Diagonale des Gehäuses genutzt, so daß eine vergleichsweise große Platine eingebaut werden kann.The transponder reading unit has a circuit board, whereby A board holder is advantageously provided in the housing on which the circuit board is arranged so that an electrical contact of the board close to the reading unit, in particular the induction coil is provided.

Weiterhin ist in der Türöffnereinheit günstigerweise eine Temperatursicherung vorgesehen, die das Entstehen heißer Oberflächen dedektieren und geeignete Gegenmaßnahmen, beispielsweise das Abschalten der Anlage, einleiten kann. In einer anderen Weiterbildung der Erfindung weist die Türöffnereinheit eine mechanische Zugfeder auf, wodurch übliche mechanische Druckfedern ersetzt werden können. Dies trägt zur Erhöhung der Sicherheit bei, da bei Zugfedern eine geringere Reibung innerhalb der Feder als bei Druckfedern entsteht. Weiterhin ist es günstig, daß vorhandene bzw. bestehende Bauteile, insbesondere die mechanischen Bauteile des Sicherheitstechnik, ersetzt werden durch elektronische Bauteile, welche in das vorhandene Türblatt bzw. in die Türzage integriert werden. Im Ergebnis sind dann viele, günstigerweise sämtliche Bauteile in der Türöffnung als elektronische Bauteile ausgebildet. Diese können besonders einfach vergossen werden. Alternativ ist auch eine Kapselung in einem Gehäuse möglich.The access control system according to the invention also has a door opener unit or a door closing unit, which is integrated in the frame or in the door leaf. in the The following are these components together as a door opener unit designated.
