Abstract

The wire-conducted transmission of video and audio signals from moving floating vehicles or an unmanned buoy located on the surface of the water to a stationary or also moving receiving system (video receiver) located on land, for example for fulfilling control and surveillance tasks, is associated with the high risk of a cable fracture. These risks no longer exist when radio transmission is chosen and, in addition, the transmitting station is also highly mobile. The mobility of the video camera/of the video camcorder and thus of the entire transmitting device can be achieved by using a diver. When he changes his position, the buoy floating on the surface is pulled along and only slightly restricts the mobility. A video camera (video camcorder) located in a water tight underwater housing is equipped at its video output with a water tight video cable, or with a seawater-tight video cable when it is used in sea water, which extends up to the water's surface and there ends in a floating water tight housing of the type and in the form of a buoy or similar. In the buoy or similar, a video transmitter is located which radiates the video and audio signals transmitted via the cable with a transmitting frequency of 2.4-2.5 GHz, that is to say outside the television transmission frequencies, in an angle of 360 DEG . One or more receiving stations (video receivers) installed on land ... Original abstract incomplete.

Description

1. Beschreibung1. Description

Die drahtgebundene Übertragung von Video- und Audiosignalen von beweglichen schwimmenden Fahrzeugen oder einer an der Wasseroberfläche befindlichen unbemannten Bojen aus zu einer am Land befindlichen stationären oder auch beweglichen Empfangsanlage (Videoempfänger), z. B. zur Erfüllung von Kontroll- und Überwachungsaufgaben, ist mit dem hohen Risiko eines Kabelbruches verbunden. Dies gilt besonders bei Einsätzen am und im Meer, wo Wellen, Strömungen und Gezeiten eine hohe Beanspruchung für Kabel darstellen.Wired transmission of video and audio signals from moving floating vehicles or an unmanned buoy on the water surface from one on land stationary or mobile receiving system (video receiver), e.g. B. to fulfill control and Monitoring tasks is associated with the high risk of a cable break. This applies particularly to Operations on and in the sea, where waves, currents and tides place high demands on cables represent.

Mit der Wahl einer Funkübertragung bestehen diese Gefahren nicht mehr und zudem ist auch noch eine hohe Mobilität der sendenden Stelle gegeben.With the choice of a radio transmission, these dangers no longer exist and there is also a high one Given the mobility of the sending agency.

Die Mobilität der Videokamera/des Videocamcorders und damit der gesamten Sendeeinrichtung kann durch Einsatz eines Tauchers erreicht werden, der sich innerhalb der maximalen Sendereichweite frei bewegen kann. Bei Ortsveränderungen wird die an der Oberfläche schwimmende Boje mitgezogen und stellt nur eine geringe Einschränkung der Mobilität dar.The mobility of the video camera / video camcorder and thus the entire transmitter can be Use of a diver who can move freely within the maximum transmission range. In the event of changes in location, the buoy floating on the surface is pulled along and only provides a small one Restriction of mobility.

2. Konfiguration2. Configuration

Eine in einem druckwasserfesten Unterwassergehäuse befindliche Videokamera (Videocamcorder) wird an ihrem (seinem) Videoausgang mit einem druckwasserdichten, bei Meerwassereinsatz mit einem seewasserfesten Video­ kabel ausgerüstet, das bis zur Wasseroberfläche reicht und dort in einem schwimmenden wasserdichten Gehäuse, in Art und Form einer Boje oder ähnlichem, endet.A video camera (video camcorder) located in a pressurized water-resistant underwater housing is activated your (his) video output with a pressure-tight, with seawater use with a seawater resistant video equipped cable that extends to the surface of the water and there in a floating waterproof housing, in the form and shape of a buoy or similar, ends.

In der Boje oder ähnlichem befindet sich ein Videosender, der die über das Kabel übertragenen Video- und Audiosignale mit einer Sendefrequenz von 2,4-2,5 GHz, also außerhalb der Fernseh-Sendefrequenzen, in einem 360°-Winkel abstrahlt.In the buoy or the like there is a video transmitter that transmits the video and via the cable Audio signals with a transmission frequency of 2.4-2.5 GHz, i.e. outside the television transmission frequencies, in radiates at a 360 ° angle.

Ein oder mehrere an Land installierte Empfangsstellen (Videoempfänger) nehmen die Signale auf, setzen diese in fernsehgerechte Video- und Audiosignale um und geben diese drahtgebunden an Videorekorder oder TV-Monitore weiter.One or more receiving points (video receivers) installed on land receive the signals and set convert these into television-compatible video and audio signals and give them wired to a video recorder or TV monitors continue.

Die Art der Stromversorgung der Sendestelle ist abhängig von der Art und Dauer des Einsatzes. Bei Kurzeinsätzen, z. B. Dauer ca. 1-3 Stunden, sind sowohl Videokamera/Videocamcorder als auch der Videosender mit örtlichen Stromversorgungen Batterien, z. B. BleiGel- oder NickelCadmium-Akkumulatoren, zu betreiben. Bei längeren Überwachungszeiten müssen alternative Stromversorgungskonzepte zum Tragen kommen.The type of power supply to the sending station depends on the type and duration of use. For short operations, e.g. B. Duration about 1-3 hours, are both video camera / video camcorder and Video transmitter with local power supplies Batteries, e.g. B. lead-gel or nickel-cadmium batteries, to operate. With longer monitoring times, alternative power supply concepts must be applied come.
