Description

Die Erfindung betrifft ein Überwachungsverfahren mit einem Bildfernsprechsystem.The invention relates to a monitoring method with a Tele-video 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. Diese 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 Bewegung im laufenden Codierungsalgorithmuss erkennt. Wenn der berechnete Bewegungsvektor einen gewissen Schwellwert überschreitet, wird der Alarm ausgelöst.From DE 38 27 928 an image telephone set is known with which such a monitoring procedure is carried out can. The one recorded by the camera of the video intercom Image changes to a previously recorded one Image, or checked for movements. If in a change in the image provided by the video camera or a movement is recognized that is a predetermined measure is exceeded, an alarm is recognized. This Evaluation can be made by comparing successive Images or by comparing a current image with a stored image or with a calculation algorithm be performed, for example, a movement recognizes in the running coding algorithm. If the calculated motion vector exceeds a certain threshold value, the alarm is triggered.

Die Alarmauslösung bewirkt den Verbindungsaufbau zu einer Kontroll- beziehungsweise Überwachungsstelle, an die ein vorgefertigter Alarmtext oder eine Alarmnachricht übertragen werden können. Zusätzlich wird das alarmauslösende Bild übertragen. Hierdurch hat die Überwachungsstelle 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 trigger causes the connection to be established Control or monitoring point to which a prefabricated Transfer alarm text or an alarm message can be. The image that triggers the alarm is also transmitted. This gives the monitoring body the opportunity to check if the alarm is triggered by a burglar or whether it is a false alarm, for example was caused 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 instead of the video telephone To use video telephone system. Such a system works for example according to the DECT standard (or the Japanese PHS standard), in which a so-called video handset wirelessly connected to a base station stands.

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.When using a video telephone or an image telephone system for a surveillance process the possibility for the burglar to report the alarm Device before establishing a communication connection with to destroy the security center or at least from the network to separate.

Der Erfindung liegt die Aufgabe zugrunde, ein sicheres Überwachungsverfahren anzugeben.The invention has for its object a safe monitoring method specify.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst.This object is achieved by the claim 1 specified features solved.

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 triggering the alarm Image sequence or the alarm-triggering image from the mobile Transfer device to base station immediately. This Transfer happens instantly, leaving a burglar has practically no possibility of doing this before the image transfer destroy mobile device. The base station then has enough Time to establish the connection to the monitoring center and the transferred and cached image there transfer.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles beschrieben.In the following, the invention is based on an exemplary embodiment described.

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 Bildtelefonie ein entsprechendes Bildfernsprechsystem vorliegt. Die Basisstation des Fernsprechsystems kann mit einem drahtlosen oder schnurgebundenen, analogen oder digitalen Kommunikationsnetz verbunden sein.For example, a cordless is assumed to be known Telephone system based on the DECT standard. Such and similar systems are for example in the Funkschau, issue 13, year 97 in the article "Comparison of DECT and PHS" described. Building on this, the handset can be equipped with a camera be so that to carry out wireless video telephony a corresponding video telephone system is available. The base station The telephone system can be used with a wireless or corded, analog or digital communication network be connected.

Zum Aufbau einer Kommunikationsverbindung zu diesem Kommunikationsnetz 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 establish a communication connection to this communication network is a number on the handset, for example entered. After establishing the connection, from the base station voice or image communication to a remote participant. Also in Data stored in the handset can only be saved after the Communication link from the handset via the base station be transmitted to the communication network.

Die Erfindung beruht auf der sofortigen Übertragung des Alarmes und des alarmauslösenden Bildes vom Mobilteil zur Basisstation.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 Alarmauslösung 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 erkannt. 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 Basisstation aus die Überwachungszentrale angewählt wird.Such a video telephone system is used for a surveillance process, for example against burglary. For the Invention, it is of secondary importance whether the alarm is triggered in the video handset or in the base station itself he follows. In one case the handset is in continuous Connection to the base station. The pictures taken are immediately transmitted to the base station, and a change in image or movement is recognized there. In another case, this detection is in the handset and if an alarm is detected, it will Immediately transmit the alarm-triggering image to the base station. In both cases, the picture or the Image sequence in the base station before before from the base station the monitoring center is selected.

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 Burglars can transfer the associated picture 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 Image acquisition sensors for the infrared range on. This can be a motion detection or the detection of image changes also take place in the dark.
