1) A VHF radio and a Class B transceiver can be connected and operated via this crossover to a common antenna.
2) Furthermore, one or more other receivers that use the frequency band of the existing antenna can be connected to the switch.
3) that is recognized by the internal structure of the electronics, which sends connected transmitting / receiving unit and thus the other connected receiver, irrelevant whether pure receiver or transmitting / receiving units, from the receiving path for the duration of the transmission to be separated.

Description
In der heutigen Zeit werden in der Berufsschifffahrt über ein spezielles Verfahren, dem sogenannten AIS, (Auotmatisches Identifikations System für Schiffe) Daten per UKW ausgetauscht.In At the present time, commercial shipping is over special procedure, the so-called AIS, (Auotmatisches Identifikations System for Ships) data exchanged via VHF.
AIS steht für Automatisches SchiffsIdentifizierungs System (Automatic Identification System).AIS stands for Automatic Ship Identification System (Automatic Identification System).
Mit AIS identifizieren sich Schiffe und geben relevante statische, reisebezogene und dynamische Daten für andere eindeutig bekannt.With AIS identify ships and give relevant static, travel-related and dynamic data for others clearly known.
Die statischen Daten geben Auskunft beispielsweise über den Schiffsnamen, das Internationale Funkrufzeichen, den Schiffstyp und die Abmessungen des Schiffes. Diese Daten sind charakteristisch für das betreffende Schiff und ermöglichen seine Identifikation. Zu den reisebezogenen Daten gehören der aktuelle Tiefgang, der Bestimmungshafen, das ETA (geplante Ankunftszeit) sowie u. U. eine Angabe zur Ladungskategorie. Diese Daten sind zumindest für eine Reise feststehend und geben Auskunft über die aktuelle Mission des Schiffes.The static data provide information, for example, about the name of the ship, the International Radio call sign, the type of ship and the dimensions of the ship. These data are characteristic of the ship in question and enable his identification. The travel-related data includes the current draft, the port of destination, the ETA (planned arrival time) as well as u. U. an indication of the charge category. This data is at least for one Travel fixed and give information about the current mission of the Ship.
Die dynamischen Daten sind für die Kollisionsverhütung mit anderen Schiffen von besonderer Bedeutung. Zu diesen Daten zählen genaue Angaben über die Position des Schiffes, seine Geschwindigkeit und sein Kurs über Grund, die exakte Vorausrichtung oder auch das momentane Drehverhalten des Schiffes.The dynamic data is for the collision prevention with other ships of particular importance. These data include accurate Information about the position of the ship, its speed and course over ground, the exact pre-alignment or the momentary turning behavior of the Ship.
Zwischen AIS-Sende/Empfangsgeräten werden diese Daten automatisch in kurzen Zeitabständen mit speziellen UKW-Sendern und Empfängern ausgetauschtBetween AIS transmitting / receiving devices These data are automatically sent in short intervals exchanged special FM transmitters and receivers
Die UKW-Sendeeinheit sendet die Datentelegramme wechselweise auf einer von zwei international festgelegten AIS-Funk-frequenzen (161,975 MHz und 162,025 MHz) aus.The FM transmitting unit sends the data telegrams alternately on one of two internationally established AIS radio frequencies (161.975 MHz and 162.025 MHz).
Die AIS Sende/Empfangseinheiten werden in 2 Klassen eingeteilt.The AIS transceivers are divided into 2 classes.
Die sogenannten „Class A" AIS Sende/Empfangseinheiten werden in der Berufsschiffahrt verwendet.The so-called "Class A "AIS transceiver units are used in professional shipping.
Die sogenannten „Class B" AIS Sende/Empfangseinheiten werden in der Sportbootschiffahrt verwendet.The so-called "Class B "AIS Transceiver Units are used in pleasure boating.
Die Class A und Class B Sende/Empfangeinheiten unterscheiden sich im übertragenen Telegramminhalt, sowie in der Wiederholrate der gesendeten Telegramme. Zudem ist die abgegebene Sendeleistung bei Class B Sende/Empfangseinheiten mit 2 W deutlich geringer als die Sendeleistung einer Class A Sende/Empfangseinheit.The Class A and Class B transmit / receive units differ in transmitted Telegram content, as well as in the repetition rate of the sent telegrams. In addition, the transmitted power is Class B transmit / receive units with 2 W significantly lower than the transmission power of a Class A transmitter / receiver unit.
Die AIS-Funkfreuenzen liegen im gleichen Frequenzband wie z. B. der UKW Sprechfunk..The AIS radio frequencies lie in the same frequency band as z. B. the VHF radio ..
Beiden Sende/Empfangseinheiten, Class A und Class B, ist gemeinsam, daß jede Einheit nur mittels einer Antenne funktioniert, die einerseits die Daten empfangen, aber auch versenden kann.Both Transmitters / Receivers, Class A and Class B, is common to each unit only by means of an antenna works, on the one hand the data receive, but also can ship.
Das bedeutet in der Realität, das Sportbootnutzer die eine Class B Sende/Empfangseinheit an Bord montieren, auch eine Antenne für dieser Sende/Empfangseinheit montieren müssen.The in reality, the pleasure boat user has a Class B transceiver on board mount, also an antenna for must mount this transmitter / receiver unit.
Dies muß in Ergänzung zu der normalerweise bereits vorhandenen UKW Funkantenne, durch eine weitere Funkantenne erfolgen.This must be in complement to the normally existing VHF radio antenna, by a another radio antenna.
Es ist dem obig beschriebenen heutigem Stand gegenüber die Aufgabe der vorliegenden Erfindung eine Weiche derart auszugestalten daß diese den Sende/Empfangsbetrieb eines UKW Funkgerätes und einer Class B Sende/Empfangseinheit gestattet, obwohl dafür an Bord nur eine gemeinsame Antenne verwendet wird. Hierbei ist zu beachten, daß die an die Weiche angeschlossenen Empfänger oder Sende/Empfangseinheiten keinen Schaden mit sich tragen, wenn einer der angeschlossenen Sender oder Sender/Empfangseinheiten senden.It is the object of the present invention as described above Invention to design a switch so that this the transmission / reception operation a VHF radio and a Class B transceiver, although allowed on board only one common antenna is used. Please note that the connected to the switch receiver or transceiver units no harm if one of the connected channels or Send transmitter / receiver units.
Die Aufgabe wird durch ein nachfolgend beschriebenes, neuartige Weiche gelöst. Die Weiche erkennt, bei welchem vorhandenen Sender bzw. Sende/Empfangseinheit Sendeleistung anliegt und schaltet die Verbindungspfade der/des verbleibenden Empfänger ab. Hierbei kann einer oder mehrere der Verbindungspfade Vorrang vor den anderen Verbindungspfaden haben. Die neuartige Weiche weist folgende Eigenschaften auf:The Task is a subsequently described, novel switch solved. The switch recognizes which existing transmitter or transceiver unit Transmit power is applied and switches the connection paths of / remaining receiver from. In this case, one or more of the connection paths can take precedence in front of the other connection paths. The novel switch has the following Properties on:
