Abstract

The use of transmitters and sensors, used for theft protection in inside rooms, for the acoustic design of a phonosystem operated in the inside room is proposed.

Description

Die Erfindung bezieht sich auf die Verwendung von Ul­ traschall- oder Infrarotsendern und Sensoren, welche in Innenräumen zum Diebstahlschutz eingesetzt sind und auf Veränderungen, insbesondere durch Personen, reagieren.The invention relates to the use of Ul ultrasound or infrared transmitters and sensors, which in Interiors are used for theft protection and on React to changes, especially by people.

Diebstahlschutzeinrichtungen, die unter Verwendung der vorbeschriebenen Sender und Sensoren Innenräume überwa­ chen, sind bereits seit einiger Zeit im Einsatz. Die reflektierten Signale werden von der Auswerteelektronik dazu verwendet, eine Art Raumbild zu erstellen. Dieses Bild wird durch jede Veränderung in dem überwachten Innenraum beeinflußt. Das System erkennt Abweichungen, wertet diese aus und steuert bestimmte Einheiten des Innenraumschutzsystems an.Anti-theft devices that use the above-described transmitters and sensors interiors Chen have been in use for some time. The Reflected signals are from the evaluation electronics used to create a kind of room image. This Image is monitored by every change in that Interior affects. The system detects deviations evaluates these and controls certain units of the Interior protection system.

Für die akustische Auslegung einer Phonoanlage ist eine Analyse der sich durch den Raum bzw. das Interieur er­ gebenden Schallverteilung wünschenswert. Bei den in der Praxis eingesetzten Anlagen gilt die Anzahl und der Aufenthaltsort der im Raum befindlichen Personen als fehlender Parameter. Bei deren Kenntnis wäre eine auto­ matische Frequenzanpassung an die sich durch unter­ schiedliche Personen ergebenden differenten Raumparame­ ter möglich.There is one for the acoustic design of a phono system Analysis of himself through the room or the interior giving sound distribution desirable. In the in the Applied systems apply the number and the Location of people in the room as missing parameter. Knowing this would be an auto Matic frequency adaptation to the by different people resulting different room parameter possible.

In der EP 0 329 201 A2 wird deshalb eine Fahrzeug-Sound­ anlage vorgeschlagen, bei der die Ausgangscharakteri­ stik der Lautsprecher in Abhängigkeit von der Anzahl der in dem Fahrzeug untergebrachten Personen korrigiert wird.EP 0 329 201 A2 therefore describes a vehicle sound plant proposed, in which the initial characteristics  stik of the loudspeaker depending on the number corrected the persons accommodated in the vehicle becomes.

Der Erfindung liegt die Aufgabe zugrunde, die Erfassung der Personenzahl in einem Innenraum zur akustischen Auslegung einer Phonoanlage in einfacher Weise durchzu­ führen.The invention has for its object the detection the number of people in an interior for acoustic Design of a phono system in a simple way to lead.

Die Aufgabe wird durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of claim 1 solved.

Durch die vorgeschlagene Verwendung werden die im Zu­ sammenhang mit dem Innenraumschutz anfallenden Informa­ tionen zusätzlich dafür verwendet, eine Aussage über die Besetzung des Innenraumes zu gewinnen. Ein eigenes Erfassungssystem für die Phonoanlage, mittels der eine Korrektur bei unterschiedlicher Besetzung des Innenrau­ mes möglich ist, kann somit entfallen.Due to the proposed use the in in connection with the informa tion additionally used to make a statement about to win the occupation of the interior. An own Recording system for the phono system, by means of one Correction for different occupancy of the interior mes is possible, can be omitted.

Die vorgeschlagene Lösung kann vorteilhaft in einem Fahrzeug realisiert werden. Bei der Innenraumüberwa­ chung von Fahrzeugen werden beispielsweise die einzel­ nen Sitzplätze durch geeignete Sender bzw. Sensoren nacheinander abgefragt und das sich daraus ergebende "Raumbild" im System abgelegt. Auf erfaßte Veränderun­ gen des Raumbildes reagiert das System, indem entspre­ chende Sicherheitseinrichtungen aktiviert werden oder - wie hier vorgeschlagen - eine Fahrzeug-Soundanlage zur Erzielung einer automatischen Frequenzanpassung ange­ steuert wird. Für den letztgenannten Zweck ist es aus­ reichend, wenn die Erfassung bzw. Anpassung nur bei eingeschalteter Soundanlage und/oder in größeren Zeit­ abständen erfolgt.The proposed solution can be advantageous in one Vehicle can be realized. When monitoring the interior For example, vehicles are used individually suitable seats or sensors sequentially queried and the resulting "Room image" stored in the system. For detected changes The system reacts to the spatial image by corresponding appropriate safety devices are activated or - as suggested here - a vehicle sound system for Achievement of an automatic frequency adjustment is controlled. For the latter purpose it is over sufficient if the acquisition or adjustment only for switched on sound system and / or in longer time intervals.
