In 1 is shown a schematic diagram of the proposed access control system. The two main modules of the access control system are

• • one indoor unit (eg home station) 1 , which in essential parts in the form of a commercial UP (flush mounted) device box after DIN 40073 (made of plastic, diameter 60 mm, depth 40 mm) installable device insert (by means of Spreizklemmen) is formed and
• • one outdoor unit (eg door station) 26 , which also in essential parts in the form of a commercial UP (flush mounted) device box after DIN 40073 (made of plastic, diameter 60 mm, depth 40 mm) installable device insert (by Spreizklemmen) is formed.

These two main assemblies indoor unit 1 and outdoor unit 26 are over a cable 20 connected to each other, which on the one hand to a cable connection 17 the indoor unit 1 and on the other hand to a cable connection 39 the outdoor unit 26 is to be connected. Usually the cable breaks through 20 at least one between indoor unit 1 and outdoor unit 26 arranged wall 42 ,

For the energy supply of the access control system is a power supply unit (power supply) 16 directly in the indoor unit 1 intended. This power supply unit 16 is on the input side to a mains connection 15 connected, which is connected to L-conductor and N-conductor of a 230 V AC mains. On the output side, there is the power supply unit 16 a DC voltage of z. B. 12 V or 24 V and not only feeds all components of the indoor unit to be supplied with energy 1 , in particular also an evaluation / processing and storage unit 5 but over the cable 20 also all building components of the outdoor unit to be supplied with energy 26 , In order to be able to easily bridge a short-term power failure, the output voltage of the power supply unit 16 an energy store 14 supplied with charging device, wherein the charging device keeps the energy storage in undisturbed operation permanently in a charged state. In case of power failure, the energy storage device takes over the power supply of the access control system for a certain period of time. As energy storage is an accumulator or capacitor.

Preferably, the power supply unit serves 16 also for supplying a potential-related switching relay 10 , which comes from the evaluation / processing and storage unit 5 can be controlled and at the terminals of an electromagnetically openable door lock 43 an access door of the access control system is connected. When controlling the switching relay 10 becomes the door lock 43 with the output voltage of the power supply unit 16 applied.

On the output side, the evaluation / processing and storage unit 5 Among other things, at least trigger a potential-free switching relay, which z. B. is predefined as fault output (direct triggering of an alarm)

The outdoor unit 26 has as central "intelligent" building block an evaluation / processing and encryption unit 38 on, being over the cable 20 Data signals between the evaluation / processing and storage unit 5 the indoor unit 1 and the evaluation / processing and encryption unit 38 the outdoor unit 26 be replaced.

• • mittels eines Transponder-Funktionselements 30 als einfaches, schnelles und wartungsfreundliches, berührungsloses System oder
• • mittels eines Fingerprint-Funktionselements 32 als biometrisches System oder
• • mittels eines PIN-Code-Funktionselements 34 oder
• • mittels eines Funk-Funktionselements 36

verifiziert, wobei mindestens eines dieser Funktionselemente 30 oder 32 oder 34 oder 36 hierzu an die Auswerte-/Verarbeitungs- und Verschlüsselungseinheit 38 angeschlossen ist. Die Auswerte-/Verarbeitungs- und Verschlüsselungseinheit 38 erkennt und filtert zusammen mit dem Funktionselement 30, 32, 34, 36 die Zutrittsberechtigungs-Information der Person, die Zutritt erhalten möchte und sendet ein dementsprechendes Berechtigungssignal verschlüsselt an die Auswerte-/Verarbeitungs- und Speichereinheit 5 der Inneneinheit 1, in welcher die Zutrittsberechtigungs-Informationen aller berechtigten Personen abgespeichert sind. Dementsprechend kann eine Überprüfung der Zutrittsberechtigung durch Vergleich der abgespeicherten Informationen mit der aktuell von der Außeneinheit 26 erhaltenen Information (Berechtigungssignal als verschlüsseltes Datensignal) erfolgen.The access control is either

• • by means of a transponder functional element 30 as a simple, fast and easy to maintain, non-contact system or
• • by means of a fingerprint function element 32 as a biometric system or
• • by means of a PIN code function element 34 or
• • by means of a wireless functional element 36

Verified, wherein at least one of these functional elements 30 or 32 or 34 or 36 for this purpose to the evaluation / processing and encryption unit 38 connected. The evaluation / processing and encryption unit 38 Detects and filters together with the functional element 30 . 32 . 34 . 36 the access authorization information of the person who wants to gain access and sends a corresponding authorization signal encrypted to the evaluation / processing and storage unit 5 the indoor unit 1 in which the access authorization information of all authorized persons are stored. Accordingly, a check of the access authorization by comparison of the stored information with the current of the outdoor unit 26 received information (authorization signal as an encrypted data signal) take place.

To increase the security against tampering does not activate the outdoor unit 26 but only the indoor unit 1 via evaluation / processing and storage unit 5 the door lock 43 via relay contact of the integrated switching relay 10 , The prerequisite for this is that the storage of access authorization information and the evaluation based on the encrypted data signal exclusively in the indoor unit 1 takes place.
