Description
Die Objektsicherung gewinnt in der heutigen Gesellschaft immer mehr an Bedeutung. Hierzu werden die verschiedensten Alarmsysteme eingesetzt. Übliche Alarmsysteme haben meist eine akustische Meldeeinrichtung, die für Menschen erkennbar auf ein Alarmereignis hinweist. Das Problem hierbei ist, dass bei Abwesenheit menschlicher Überwacher eine Erkennung des Alarmereignisses und somit eine daraufhin notwendige Reaktion ausbleibt.The Property security is gaining more and more in today's society in importance. For this the most different alarm systems are used. Usual alarm systems Most have an acoustic message device that is for people identifiable as an alarm event. The problem here is that in the absence of human monitors one Detection of the alarm event and thus a necessary Reaction fails.
Ein Alarmsystem bei dem der ausgelöste Alarm keine, oder nur verspätete Reaktion nach sich zieht, ist in vielen Fällen nutzlos. Es wird also ein Sensor benötigt, der beim Auslösen eines akustisch signalisierten Alarmereignisses ein sekundäres Alarmereignis auslöst, dass die Behandlung des ursprünglichen Alarms ermöglicht oder beschleunigt. Die im Schutzanspruch 1 angegebene Erfindung löst dieses Problem.One Alarm system in which the alarm triggered none, or only late Reaction is useless in many cases. So it will be a sensor is needed the triggering an acoustically signaled alarm event, a secondary alarm event triggers, that the treatment of the original Alarms enabled or accelerated. The protection specified in claim 1 invention solve this Problem.
Mit der Erfindung wird erreicht, dass ein eingetretenes Alarmereignis (z.B. das Auslösen eines Autoalarms) erkannt, und gemäß Schutzanspruch 2 an ein anderes System (z.B. die Überwachungszentrale eines Parkhauses) weitergeleitet werden kann. Dies ermöglicht die sofortige Anwendung von Prozeduren zur Begegnung besagter Alarmereignisse.With the invention is achieved that a occurred alarm event (e.g., triggering a car alarm) detected, and according to protection claim 2 to another System (e.g., the central office a parking garage) can be forwarded. This allows the Immediate application of procedures for meeting said alarm events.
Gemäß Schutzanspruch 3 können mehrere dieser Sensoren zu einem Sensornetzwerk verschaltet werden. Dies kann zum Zwecke der Vergrößerung der Reichweite, Verringerung der Fehleranfälligkeit oder zur Lokalisation des Alarmereignisses (z.B. mittels Triangulation) erfolgen. Ein lokalisiertes Ereignis kann als Grundlage weiterer Prozeduren zur Begegnung des Ereignisses dienen (ausrichten von Kameras, verschließen von Türen oder Schranken, etc.). Zudem ist die Verwendung von Verbundsensoren möglich, also Sensoren, bei denen mehrere Mikrofone mit einer Auswertelektronik verschaltet werden.According to protection claim 3 can several of these sensors are interconnected to a sensor network. This may be for the purpose of enlarging the Range, reduced susceptibility or localization the alarm event (e.g., by triangulation). One localized event can be used as the basis for further procedures Serve encounter of the event (align cameras, close off Doors or Barriers, etc.). In addition, the use of composite sensors is possible, ie Sensors in which several microphones with an electronic evaluation be interconnected.
Zur besseren Verarbeitung durch Sensorgruppen erkannter Ereignisse können gemäß Schutzanspruch 4 weitere zentrale oder verteilte Datenverarbeitungssysteme, auch in redundanter Form, verwendet werden.to better processing by sensor groups detected events can according to protection claim 4 more central or distributed data processing systems, too in redundant form.

Realisierungsmöglichkeit
ist in
Zur Detektion des Ereignisses und des Laufzeitunterschiedes innerhalb eines Verbundsensors wird das Signal der beiden Mikrofone M1 und M2 digitalisiert und einem Mikrocontroller, FPGA, Industrie-PC, o.ä. verarbeitet. Hierzu wird das digitalisierte Signal gepuffert und über eine Fast-Furier-Transformation umgewandelt. Die Äderung des Spektrums wird verfolgt, und mit den Frequenzprofilen der gesuchten Ereignisse verglichen. Wenn ein Ereignis erkannt wurde, werden die gepufferten Signale beider Mikrofone nach dem Frequenzprofil digital gefiltert und Kreuzkorreliert. Das Maximum der Korrelation ergibt den benötigten Laufzeitunterschied Δt für den Verbundsensor.to Detection of the event and the runtime difference within a composite sensor is the signal of the two microphones M1 and M2 digitized and a microcontroller, FPGA, industrial PC, etc. processed. For this purpose, the digitized signal is buffered and via a Converted to fast-furier transformation. The veining of the spectrum is tracked and compared with the frequency profiles of the searched events. When an event is detected, the buffered signals become both microphones digitally filtered according to the frequency profile and cross-correlated. The maximum of the correlation gives the required transit time difference Δt for the composite sensor.
