Abstract

The transceiver (4) system transmits signals from a personal transmitter to a receiver (5) which raises an alarm on non-reception of signals. The receiver contains a tester checking sequentially or simultaneously specific signals from all transmitters, triggering the alarm output signal on absence of any one. Preferably, IR radiation is used for the signal transmission, with the signals of pulsed type. The man overboard situation may also cover theft. The alarm signal is typically acoustic.

Description

Aus der Schiffahrt ist eine Einrichtung bekannt, welche sobald eine Person zusammen mit einem Sender, welchen sie bei sich trägt, und welcher sobald er mit Wasser in Kontakt kommt beginnt elektromagnetische Wellen auszusenden, über Bord fällt ein Signal gibt um die Rettung der entsprechenden Person zu ermöglichen. Dabei empfängt ein Empfänger an Bord die Signale des Senders aus dem Wasser.A device is known from shipping, which as soon as a person together with a transmitter, which she carries with her, and which as soon as he comes into contact with water starts to emit electromagnetic waves, A signal is given overboard to rescue the person concerned enable. A receiver on board receives the signals from the transmitter the water.

Diese Einrichtung hat aber den Nachteil, daß sie aufgrund der hohen Reichweite, welche ein solcher Sender erzielen muß, zum einen sehr teuer in der Herstellung und zum zweiten recht aufwendig in der Fertigung ist.However, this device has the disadvantage that due to the long range, which such a transmitter must achieve, on the one hand, very expensive to manufacture and secondly, it is quite complex to manufacture.

Desweiteren ist der Sender aufgrund seiner recht hohen Sendeleistung auch aus herstellerspezifischen Gründen recht groß und dadurch umständlich zu handhaben und mit sich zu führen.Furthermore, the transmitter is also off due to its quite high transmission power manufacturer-specific reasons quite large and therefore cumbersome handle and carry with you.

Gemäß der Erfindung wird diese Aufgabe durch die im kennzeichnenden Teil des Schutzanspruches 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of protection claim 1 .

Die Vorteile der Erfindung liegen darin, daß Sender mit einer kleineren Reichweite, etwa entsprechend der Bootslänge, die dadurch kleiner ausgebildet werden können, einsetzbar sind, und daß automatisch sobald eine Person sich mit ihrem spezifischen Sender außerhalb des Reichweitenbereiches, das heißt außerhalb des Schiffes und somit während der Fahrt "über Bord", befindet ein Alarm, oder eine sonstige Rettungsmaßnahme ausgelöst wird.The advantages of the invention are that transmitters with a smaller one Range, roughly according to the length of the boat, which makes it smaller can be used, and that automatically as soon as a person is with their specific transmitter outside the range, that is outside the ship and thus during the voyage "overboard" Alarm, or another rescue operation is triggered.

Auch ein Abschwächen der Versorgungsspannung des Senders wäre durch einen Fehlalarm sofort bemerkbar. The supply voltage of the transmitter would also be weakened by one False alarm is immediately noticeable.  

Vorteilhafte und zweckmäßige Weiterbildungen und Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous and expedient further developments and refinements of Invention are described in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird anhand eines, in einer Figur dargestellten Blockschaltbildes erläutert.An embodiment of the invention is based on a, in a figure block diagram shown explained.

Ein Pulsgenerator (1) schickt in einem konstanten Abstand Stromimpulse zum HF-Sender (2) dieser sendet daraufhin eine bestimmte durch den Kodierer (3) festgelegte und einstellbare Signalfolge aus.A pulse generator ( 1 ) sends current pulses to the RF transmitter ( 2 ) at a constant distance, which then sends out a specific signal sequence defined and adjustable by the encoder ( 3 ).

Bei Verwendung mehrerer Sendeeinrichtungen (4) muß das durch den Kodierer festgelegte Signalmuster bei jeder Sendeeinrichtung (4) unterschiedlich sein. Kommt ein für eine Sendeeinrichtung (4) spezifisches Sendesignal zum Empfänger (6) der Empfangseinrichtung (5), so wird dessen Signal im Dekoder (7) dekodiert und anschließend um eine durch den Zeitgeber (8) festgelegte Zeitspanne, welche mindestens so lang sein muß wie der Abstand zweier Impulse des Pulsgenerators (1) verlängert. Dadurch entsteht bei gleichbleibendem Eingang an Impulsen im Empfänger (6) ein andauernder, unveränderter Ausgangsimpuls am Zeitgeber (8). Sollte sich eine Sendeeinrichtung (4) aus dem Empfangsbereiches des Empfängers (6) entfernen so ist dessen Sendesignal nicht mehr zu empfangen, dadurch wird der Ausgangsimpuls des Zeitgebers (8) durch den Dekoder (7) nicht mehr verlängert und nach Verstreichen der Zeitspanne des Zeitgebers (8) wird durch den Alarmgeber (9) ein Alarm oder ein anderes Ausgangssignal ausgelöst, was in einer "Mann über Bord" - Situation gegeben ist.If several transmission devices ( 4 ) are used, the signal pattern defined by the encoder must be different for each transmission device ( 4 ). If a transmission signal specific to a transmission device ( 4 ) arrives at the receiver ( 6 ) of the reception device ( 5 ), its signal is decoded in the decoder ( 7 ) and then by a period of time defined by the timer ( 8 ), which must be at least as long how the distance between two pulses of the pulse generator ( 1 ) is extended. This creates a constant, unchanged output pulse at the timer ( 8 ) while the input of pulses in the receiver ( 6 ) remains the same. If a transmitting device ( 4 ) moves away from the receiving area of the receiver ( 6 ), its transmitting signal can no longer be received, as a result of which the output pulse of the timer ( 8 ) is no longer extended by the decoder ( 7 ) and after the time period of the timer has elapsed ( 8 ) an alarm or another output signal is triggered by the alarm transmitter ( 9 ), which is the case in a "man overboard" situation.
