Abstract
Description
Die Erfindung betrifft eine elektromechanische Schalteinrichtung
nach dem Oberbegriff des Anspruchs 1. Die Einrichtung hat ein
mit einem Signal aktivierbaren Empfangsteil, das nach Überprüfung
der Berechtigung des empfangenen Signals in einem Mikroprozessor
einen Schaltvorgang auslöst. Die Erfindung betrifft
insbesondere eine Alarmanlage, bestehend aus einer Alarmzentrale,
die durch ein Signal aktivierbar ist, die mit Sensoren zur
Überwachung eines oder mehrerer Räume gegen das unberechtigte
Eindringen versehen ist, und mindestens einem Schlüssel- Schloßsystem
zum Schärfen und/oder Entschärfen der Alarmanlage.The invention relates to an electromechanical switching device
according to the preamble of
Es gibt verschiedene Alarmanlagen, die je nach Art der eingesetzten Sensoren für eine punktförmige Sicherung z.B. durch elektrische Türkontakte, für eine linienförmige Sicherung z.B. durch Licht- oder Ultraschallschranken oder durch eine Flächensicherung z.B. durch eingebaute Reißdrähte oder Körperschallmelder das Eindringen unbefugter Personen erfassen.There are various alarm systems, depending on the type of alarm used Sensors for point protection e.g. by electrical door contacts, for a linear fuse e.g. by light or ultrasonic barriers or by area security e.g. through built-in tear wires or structure-borne sound detectors detect intrusion by unauthorized persons.
Bei allen Alarmanlagen ist es erforderlich, eine Scharf- und Unscharfschaltung vorzusehen, wobei aus versicherungstechnischen Gründen heute zunehmend eine kombinierte Schließ- und Scharf/Unscharfschaltung verlangt wird. Diese erfolgt bei herkömmlichen Alarmanlagen überwiegend durch elektromechanische Schaltelemente über das Zugangsschloß für das zu schützende Objekt, wobei die Alarmzentrale mit mechanischen Schaltelementen angesteuert wird. Hierzu ist eine aufwendige Verdrahtung der Eingangstür erforderlich, die insbesondere bei einer Nachrüstung zu erheblichen optischen und funktionellen Nachteilen führt, die beim täglichen Gebrauch sehr stören. All alarm systems require an arming and Disarming to be provided, whereby from actuarial Combined locking and arming / disarming are becoming increasingly common today is required. This is done with conventional Alarm systems mainly through electromechanical switching elements via the access lock for the object to be protected, the Alarm center is controlled with mechanical switching elements. This requires complex wiring of the entrance door, which is particularly significant when retrofitting optical and functional disadvantages that leads to everyday Very disrupt use.
Ein weiterer Nachteil bei den herkömmlichen Anlagen besteht darin, daß die mechanischen Schaltelemente oftmals durch Schlüssel gesichert sind, die leicht verloren gehen und dann unrechtmäßig dupliziert werden können. Bei einem Verlust derartiger Schlüssel ist dann eine Wiederinbetriebnahme einer gesicherter Alarmanlage erforderlich.Another disadvantage with conventional systems is in that the mechanical switching elements often by key that are easily lost and then illegally secured can be duplicated. If such a loss occurs The key is then to restart a secured one Alarm system required.
Ganz allgemein besteht Bedarf nach aus vorhandenen Serienteilen aufgebauten elektro-mechanischen Schaltanlagen, die einfach und sicher zu bedienen und ggf. leicht nachrüstbar sind.In general there is a need for existing series parts built electro-mechanical switchgear that is simple and are safe to use and can easily be retrofitted.
Aus der EP-A-0 525 730 ist eine Einrichtung gemäß Oberbegriff
des Anspruchs 1 bekannt.From EP-A-0 525 730 is a device according to the preamble
of
Aufgabe der vorliegenden Erfindung ist es, eine derartige Schaltanlage zu entwickeln, die unkompliziert und sicher ist.The object of the present invention is to provide such Switchgear to develop the is simple and safe.
Aufgabe der vorliegenden Erfindung ist es ferner, eine Alarmanlage mit kombinierter Schließ- Scharf- und Unscharfeinstellung anzubieten, die berührungslos arbeitet und die auch bei Verlust eines Schlüssels wieder leicht in einen gesicherten Betriebszustand zu bringen ist.Another object of the present invention is an alarm system with combined To offer closing, focusing and disarming works without contact, even if you lose a key easy to bring back into a safe operating state is.
Diese Aufgabe wird erfindungsgemäß durch die in den Patentansprüchen angegebenen Merkmale gelöst. Durch Anbringung einer neuen Steuerung im Schlüssel/Schloßsystem wird die Verdrahtung der Tür überflüssig und eine absolute Sicherheit gegen Fehlschaltungen gewährleistet. Auch bei Sabotage und/oder unberechtigter Benutzung von verlorenen Schlüsseln kann die neue Alarmanlage nicht außer Funktion gesetzt werden.This object is achieved by the in the claims specified features solved. By attaching a New control in the key / lock system is the wiring the door is superfluous and absolute security against incorrect switching guaranteed. Even in the event of sabotage and / or unauthorized persons The new alarm system can use lost keys cannot be disabled.
Das erfindungsgemäße System besteht im wesentlichen aus einem magnetischen Schaltelement, welches an der Eingangstür angebracht ist und mindestens einem Sender, der fest am Schlüssel befestigt wird. Über diesen Sender wird ein an der Alarmzentrale angeschlossener Empfänger erreicht, der die Anlage schärft oder entschärft. The system according to the invention essentially consists of a magnetic switching element, which is attached to the entrance door and at least one transmitter that is firmly attached to the key is attached. This is the transmitter at the alarm center connected receiver that sharpens the system or defused.
In einer bevorzugten Ausführungsform der Erfindung können die Schließfunktionen noch dadurch erweitert werden, daß bei Linksdrehung des Schlüssels in dem zu verriegelnden Schloß der oder die im Inneren des Schlüssels angeordneten Schalter in einer bestimmten Reihenfolge berührungslos geschaltet werden. Bei jedem Schaltvorgang ergeht ein Impuls an den Prozessor im Schlüssel, der ein kodiertes Signal an das Empfangsteil der Alarmanlage sendet.In a preferred embodiment of the invention, the Locking functions can be expanded by turning left the key in the lock to be locked or the switches located inside the key in one certain order are switched contactless. At with each switching process there is an impulse to the processor in the Key that sends a coded signal to the receiving part of the Alarm system sends.
Die in einer bestimmten Reihenfolge im Empfangsteil eintreffenden Signale werden von einem Mikroprozessor überprüft. Sofern der eingehende Code mit dem Berechtigungscode übereinstimmt, gibt der Mikroprozessor ein Signal zum Aktivieren der Alarmanlage an die Alarmzentrale weiter.Those arriving in the receiving section in a certain order Signals are checked by a microprocessor. Provided the incoming code matches the authorization code, the microprocessor gives a signal to activate the alarm system to the alarm center.
Durch die Rechtsdrehung des Schlüssels wird - analog zum vorher beschriebenen Schließvorgang - das kodierte Funksignal zum Deaktivieren der Alarmanlage gesendet. Es ist vorteilhaft, wenn bei jedem Schließvorgang der Code des Funksignals über einen Zufallsgenerator verändert, so daß ein Kennen des Funkcodes nicht für ein unberechtigtes Eindringen genutzt werden kann.By turning the key to the right - analogous to the previous one described closing process - the coded radio signal for deactivation sent to the alarm system. It is advantageous if at each time the radio signal is closed via a random number generator changed so that knowing the radio code does not can be used for unauthorized intrusion.
Eine Notfunktion im Schlüsselsender ist dadurch gewährleistet, daß beim Ausbleiben des Funksignals eine manuelle Unscharfschaltung der Alarmanlage ermöglicht wird. Der Benutzer der Alarmanlage erfährt dies dadurch, daß ein akustisches oder optisches Signal nach dem Öffnen der Tür von der Alarmzentrale erzeugt wird. Daraufhin hat der Benutzer innerhalb eines bestimmten Zeitintervalls Gelegenheit die Alarmanlage manuell unscharf zu schalten. Hierzu kann er den in einem Schlüsseltransponder eingegebenen Code von der Alarmzentrale einlesen lassen, wobei dies vorzugsweise über eine Magnetspule erfolgt, die mit einem Mikroprozessor verbunden ist. An emergency function in the key transmitter is guaranteed that if there is no radio signal, manual disarming the alarm system is enabled. The user of the Alarm system experiences this by the fact that an acoustic or optical Signal generated by the alarm center after opening the door becomes. Thereupon the user has within a certain Time interval opportunity to disarm the alarm system manually to switch. He can do this in a key transponder Have the code entered read in by the alarm center, whereby this is preferably done via a magnetic coil with a Microprocessor is connected.
Es ist möglich, die Sende- und Empfangsanlage der erfindungsgemäßen Alarmanlage so auszurüsten, daß bis zu zehn verschiedene Schlüsselsender eingelesen und überprüft werden können. Die jeweiligen Schlüssel-Kennungen sind veränderbar, was vorzugsweise über eine Master-Karte mittels Magnetspule und Mikroprozessor des Empfängers erfolgt. Es ist vorteilhaft, wenn allein mit dieser Master-Karte transpondergesteuert, Schlüsselberechtigungen vergeben oder gelöscht werden.It is possible to use the transmitting and receiving system of the invention Equip alarm system so that up to ten different ones Key transmitter can be read and checked. The respective key identifiers are changeable, which is preferable via a master card using a magnetic coil and microprocessor of the recipient. It is beneficial if alone transponder-controlled with this master card, key authorizations assigned or deleted.

Die erfindungsgemäße Schaltanlage läßt sich auf verschiedene Schaltvorgänge anwenden, wobei bevorzugt solche mit elektromeschanischem Antrieb, aber auch bisher stationäre Energieanschlüsse schaltbar sind. Als Beispiele können hier folgende Anwendungsbereiche genannt werden: Der Antrieb von Jalousien, Rolläden oder Wasserpumpen im Haushaltsbereich sowie Servomotorenantriebe im industriellen und Freizeitbereich. Bei der stationären Energieversorgung lassen sich neue Lösungen für das Ein- bzw. Ausschalten von Heizgeräten, für die Herd-Ofen-Energieversorgung, für den Stand-by-Betrieb von Fernsehgeräten, Videorecordern usw. oder auch für Außensteckdosen finden. Hier ist ein breiter Anwendungsbereich des erfindungsgemäßen Schaltprinzips gegeben.The switchgear according to the invention can be different Apply switching operations, preferably those with electromechanical Drive, but also previously stationary energy connections are switchable. As examples here are the following Areas of application are mentioned: The drive of blinds, Roller shutters or water pumps in the household sector as well as servo motor drives in the industrial and leisure sector. At the stationary Energy supply can be new solutions for that Switching on and off of heaters for the stove-oven energy supply, for the stand-by operation of television sets, Find VCRs etc. or even for external sockets. Here is a broad application of the switching principle according to the invention given.
In einer bevorzugten Variante werden zwei Reedschalter in einem Schlüssel- oder Schaltersystem zu einem Mehrkomponentenschalter vereinigt. Dadurch ergibt sich eine Verbesserung des Komforts bei der Bedienung und eine erhöhte Sicherheit in der Verschlußstellung.In a preferred variant, two reed switches are in one Key or switch system for a multi-component switch united. This results in an improvement in comfort in operation and increased security in the closed position.
Beim Bewegen dieses Mehrkomponenten-Schalters können über die Reedschalter Signalfolgen ausgelöst werden, wie z.B. 1-2 bei einer Rechtsdrehung oder 2-1 bei einer Linksdrehung des Schlüssels bzw. Schalters im Magnetfeld. Die Schaltanlage könnte somit aufgrund einfacher Logik erkennen, ob die Anlage aktiviert oder deaktiviert werden soll. Auch besteht die Möglichkeit, die Alarm- oder Aktivierungsfunktion erst nach zweimaligem Umschließen in Kraft zu setzen, so daß eine beschränkte Sicherheitsfunktion durch einmaliges Umschließen schon ohne Scharfstellen der Alarmanlage möglich ist. Bei der Verwendung nur eines Reedschalters ist die entsprechende Sicherheitsfunktion nur mit einer aufwendigen logischen Schaltung möglich.When moving this multi-component switch you can use the Reed switch signal sequences are triggered, e.g. 1-2 at a right turn or 2-1 left turn of the key or switch in the magnetic field. The switchgear could thus recognize based on simple logic whether the system is activated or should be deactivated. There is also the possibility of Alarm or activation function only after two enclosures to put into effect so that a limited security function by enclosing it once without focusing Alarm system is possible. When using only one reed switch the corresponding safety function is only with one complex logic circuit possible.
