Abstract

The invention relates to a surveillance method with a wireless video telephone system. According to the invention, a base station is connected to a communications network and a mobile video unit with a camera is used for surveillance. A current recorded image is checked for changes and an alarm is triggered and a surveillance unit is dialled if a predetermined difference is detected. The image that has triggered the alarm is immediately transmitted from the mobile unit to the base station where it is stored, at least until being delivered to the communications network.

Description

Beschreibungdescription

Einbruchserkennung mit einem BildtelefonIntrusion detection with a videophone

Die Erfindung betrifft ein Überwachungsverfahren mit einem Bildfernsprechsystem.The invention relates to a monitoring method with an image telephone system.

Aus der DE 38 27 928 ist ein Bildfernsprechgerät bekannt, mit dem ein derartiges Überwachungsverfahren durchgeführt werden kann. Das von der Kamera des Bildfernsprechgerätes aufgenommene Bild wird auf Veränderungen, zu einem vorher aufgenommenen Bild, beziehungsweise auf Bewegungen überprüft. Wenn in dem von der Videokamera gelieferten Bild eine Veränderung oder eine Bewegung erkannt wird, die ein vorgegebenes Maß überschreitet, so wird auf einen Alarmfall erkannt. DieseFrom DE 38 27 928 an image telephone set is known with which such a monitoring method can be carried out. The image recorded by the camera of the video telephone set is checked for changes to a previously recorded image or for movements. If a change or movement is detected in the image supplied by the video camera that exceeds a predetermined dimension, an alarm is recognized. This

Auswertung kann durch einen Vergleich von aufeinanderfolgenden Bildern oder durch den Vergleich eines aktuellen Bildes mit einem gespeicherten Bild oder auch durch einen Rechenalgorithmus durchgeführt werden, der beispielsweise eine Bewe- gung im laufenden Codierungsalgorithmuss erkennt. Wenn der berechnete Bewegungsvektor einen gewissen Schwellwert überschreitet, wird der Alarm ausgelöst.Evaluation can be carried out by comparing successive images or by comparing a current image with a stored image or also by means of a computing algorithm which, for example, recognizes a movement in the current coding algorithm. When the calculated motion vector exceeds a certain threshold, the alarm is triggered.

Die Alarmauslösung bewirkt den Verbindungsaufbau zu einer Kontroll- beziehungsweise Uberwachungsstelle, an die ein vorgefertigter Alarmtext oder eine Alarmnachricht übertragen werden können. Zusätzlich wird das alarmauslösende Bild übertragen. Hierdurch hat die Uberwachungsstelle die Möglichkeit zu überprüfen, ob der Alarm durch einen Einbrecher ausgelöst wurde, oder ob es sich um einen Fehlalarm handelt, der beispielsweise durch eine Katze verursacht wurde.The alarm triggers the establishment of a connection to a control or monitoring point to which a pre-made alarm text or an alarm message can be transmitted. The image that triggers the alarm is also transmitted. This enables the monitoring agency to check whether the alarm was triggered by a burglar or whether it is a false alarm that was caused, for example, by a cat.

Es ist denkbar, anstelle des Bildfernsprechgerätes ein drahtloses Bildfernsprechsystem zu verwenden. Ein solches System arbeitet beispielsweise nach dem DECT-Standard (oder dem japanischen PHS-Standard) , bei dem ein sogenanntes Video- Mobilteil drahtlos mit einer Basisstation in Verbindung steht.It is conceivable to use a wireless video telephone system instead of the video telephone device. Such a system works, for example, according to the DECT standard (or the Japanese PHS standard), in which a so-called video Handset is wirelessly connected to a base station.

Bei Verwendung eines Bildfernsprechendgerätes beziehungsweise eines Bildfernsprechsystems für ein Überwachungsverfahren besteht für den Einbrecher die Möglichkeit, das den Alarm meldende Gerät vor dem Aufbau einer Kommunikationsverbindung mit der Sicherheitszentrale zu zerstören oder zumindest vom Netz zu trennen.If an image telephone device or an image telephone system is used for a monitoring method, the burglar has the option of destroying the device reporting the alarm or at least disconnecting it from the network before establishing a communication link with the security center.

Der Erfindung liegt die Aufgabe zugrunde, ein sicheres Uberwachungsverfahren anzugeben.The invention is based on the object of specifying a secure monitoring method.

Diese Aufgabe wird erfindungsgemäß durch die im Patentan- spruch 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in patent claim 1.

Die Erfindung geht von der Idee aus, die alarmauslösende Bildsequenz beziehungsweise das alarmauslösende Bild vom mobilen Gerät sofort zur Basisstation zu übertragen. Diese Übertragung geschieht unverzüglich, so daß ein Einbrecher praktisch keine Möglichkeit hat, vor der Bildübertragung das mobile Gerät zu zerstören. Die Basisstation hat dann genügend Zeit, die Verbindung zur Überwachungszentrale aufzubauen und das übertragene und zwischengespeicherte Bild dorthin zu übertragen.The invention is based on the idea of transmitting the alarm-triggering image sequence or the alarm-triggering image from the mobile device to the base station immediately. This transmission takes place immediately, so that a burglar has practically no possibility of destroying the mobile device before the image transmission. The base station then has enough time to establish the connection to the monitoring center and to transfer the transmitted and buffered image there.

Im folgenden wird die Erfindung anhand eines Ausführungsbei- spieles beschrieben.The invention is described below with the aid of an exemplary embodiment.

Als bekannt vorausgesetzt wird beispielsweise ein schnurloses Telefonsystem nach dem DECT-Standard. Solche und ähnliche Systeme sind beispielsweise in der Funkschau, Heft 13, Jahrgang 97 in dem Artikel "Vergleich von DECT und PHS" beschrieben. Darauf aufbauend kann das Mobilteil mit einer Kamera versehen werden, so daß zur Durchführung einer drahtlosen Bildtelefo- nie ein entsprechendes Bildfernsprechsystem vorliegt. Die Basisstation des Fernsprechsystems kann mit einem drahtlosen oder schnürgebundenen, analogen oder digitalen Kommunikationsnetz verbunden sein.For example, a cordless telephone system based on the DECT standard is assumed to be known. Such and similar systems are described, for example, in Funkschau, Issue 13, Volume 97 in the article "Comparison of DECT and PHS". Building on this, the handset can be provided with a camera, so that a corresponding video telephone system is available for carrying out wireless video telephony. The base station of the telephone system can be used with a wireless or linked, analog or digital communication network.

Zum Aufbau einer Kommunikationsverbindung zu diesem Kommuni- kationsnetz wird beispielsweise am Mobilteil eine Rufnummer eingegeben. Nach dem Aufbau der Verbindung, von der Basisstation aus, kann die Sprach- beziehungsweise Bildkommunikation zu einem entfernten Teilnehmer durchgeführt werden. Auch im Mobilteil gespeicherte Daten können erst nach dem Aufbau der Kommunikationsverbindung vom Mobilteil über die Basisstation zum Kommunikationsnetz übertragen werden.To set up a communication connection to this communication network, a phone number is entered on the handset, for example. After the connection has been set up from the base station, the voice or image communication can be carried out to a remote subscriber. Data stored in the handset can also only be transmitted from the handset to the communication network via the base station after the communication connection has been established.

Die Erfindung beruht auf der sofortigen Übertragung des Alarmes und des alarmauslösenden Bildes vom Mobilteil zur Basis- Station.The invention is based on the immediate transmission of the alarm and the alarm-triggering image from the handset to the base station.

Ein solches Bildfernsprechsystem wird für ein Überwachungsverfahren, beispielsweise gegen Einbruch, eingesetzt. Für die Erfindung ist es von untergeordneter Bedeutung, ob die Alar- mauslösung im Video-Mobilteil oder in der Basisstation selbst erfolgt. In einem Fall steht das Mobilteil in kontinuierlicher Verbindung mit der Basisstation. Die aufgenommen Bilder werden dabei unverzüglich zur Basisstation übertragen, und dort wird eine Bildänderung beziehungsweise eine Bewegung er- kannt. In einem anderen Fall wird diese Erkennung im Mobilteil durchgeführt, und bei Erkennung auf einen Alarm wird das alarmauslösende Bild unverzüglich zur Basisstation übertragen. In beiden Fällen liegt das Bild beziehungsweise die Bildsequenz in der Basisstation vor, bevor von der Basissta- tion aus die Überwachungszentrale angewählt wird.Such a video telephone system is used for a surveillance method, for example against burglary. It is of secondary importance for the invention whether the alarm is triggered in the video handset or in the base station itself. In one case, the handset is in continuous connection with the base station. The captured images are immediately transmitted to the base station, where an image change or movement is recognized. In another case, this detection is carried out in the handset, and when an alarm is detected, the alarm-triggering image is immediately transmitted to the base station. In both cases, the image or the image sequence is available in the base station before the monitoring center is selected from the base station.

Bei einer Zerstörung des Mobilteils beispielsweise durch einen Einbrecher kann die Übertragung des zugehörigen Bildes nicht mehr verhindert werden.If the handset is destroyed, for example by a burglar, the transmission of the associated image can no longer be prevented.

Bei einer Weiterbildung der Erfindung weist die Kamera des Video-Mobilteils Bildaufnahmesensoren für den Infrarotbereich auf. Hierdurch kann eine Bewegungserkennung beziehungsweise die Erkennung von Bildveränderungen auch bei Dunkelheit erfolgen. In a development of the invention, the camera of the video handset has image sensors for the infrared range on. In this way, motion detection or the detection of image changes can also take place in the dark.
