Description

Anordnung zur Sicherung des Schiffs- und Flugverkehrs Es sind Anordnungen zur Sicherung des Schiffs- und Flugverkehrs mit Hochfrequenzwellen bekannt, bei denen jedes Fahrzeug mit einem Sender und einem Empfänger ausgerüstet ist und die von den Sendestationen ausgehenden Hochfrequenzwellen in mit den Empfängern verbundenen Signaleinrichtungen bzw. Anzeigegeräten :ausgewertet werden. Die grundsätzliche Schwierigkeit bei derartigen Anordnungen besteht darin, zu verhindern, d:aß die eigene Sendestation den Empfänger des gleichen Fahrzeuges beeinflußt und damit eine zuverlässige Verkehrssicherung ausschließt. Dies wird z. B. dadurch erreicht, daß Sender und Empfänger abwechselnd in bestimmtem Tastrhy thmus eingeschaltet werden. Während der Wirksamkeit des Senders ist :also der .eigene Empfangsapparat abgeschaltet und bei Wirksamkeit des Empfangsgerätes die Sendestation außer- Bietrieb-.gesetzt. Diese abwechselnde Inbetriebsetzung von Sender und Empfänger geschieht durch einfaches Zu- und Abschalten.Order to secure ship and air traffic There are orders known for securing shipping and air traffic with high frequency waves each vehicle is equipped with a transmitter and a receiver and the high-frequency waves emanating from the transmitting stations in connected to the receivers Signal devices or display devices: are evaluated. The basic one The difficulty with such arrangements is to prevent the own transmitting station influences the receiver of the same vehicle and thus a excludes reliable traffic safety. This is z. B. achieved in that The transmitter and receiver are switched on alternately in a certain tactile rhythm. While the transmitter is in effect: that is, the receiver's own receiver is switched off and when the receiving device is effective, the transmitting station is out of operation. This alternating start-up of the transmitter and receiver is done by simple Switching on and off.

Die Gefahr derartiger Sicherungsverfahrten mit :abwechselnder Wirksamkeit von Sender und Empfänger liegt darin, daß zufälligerweise mehrere Fahrzeuge den gleichen Rhythmus des Umtastens benutzen. In diesem Falle können sich beide Fahrzeuge bereits: in der gegenseitigen Gefahrenzone befinden, ohne einander wahrzunehmen, da die Empfänger des ,einen Fahrzeuges immer nur in dem Zeitbereich wirksam sind, innerhalb dessen sich die Sender außer Bletrieb befinden bzw. umgekehrt. Um einen derartigen Zustand auszuschließen, müßte man jeder Fahrzeugstation einen bestimmten Rhythmus des Umtastens zuteilen, was international geschehen müßte und deshalb organisatorische Schwierigkeiten bereiten würde. Die vorliegende Erfindung vermeidet diesen Nachteil dadurch, daß jede Fahrzeugstation einen anderen Umtastrhythmus spricht. Diese Rufzeichen sind internatl'#e@4' festgelegt und. besitzen keine Wiederholung-. in der ganzen Welt. Es ist dann gleichgültig, in welcher Weise die Kollektoren umlaufen, da es immer gewisse Zeitbereiche gibt,, in denen ein Wechselverkehr möglich ist. Durch Anwendung dieses Umtastrhythmus nach der Erfindung ist ein Gleichlauf zwischen den, Stationen. zweier Fahrzeuge ausgeschlossen und die einwandfreie Wirkungsweise der Sicherungsanlage gewährleistet.The danger of such security procedures with alternating effectiveness of the transmitter and receiver lies in the fact that several vehicles accidentally use the same rhythm of keying. In this case, both vehicles can already be in the mutual danger zone without noticing each other, since the receivers of the one vehicle are only effective in the time range within which the transmitters are out of operation or vice versa. In order to rule out such a situation, each vehicle station would have to be assigned a certain rhythm of keying, which would have to be done internationally and would therefore cause organizational difficulties. The present invention avoids this disadvantage in that each vehicle station has a different keying rhythm speaks. These callsigns are internatl '# e @ 4' and. have no repetition. in the whole world. It is then irrelevant in which way the collectors circulate, since there are always certain time ranges in which alternating traffic is possible. By using this switching rhythm according to the invention, there is synchronization between the stations. two vehicles are excluded and the proper functioning of the security system is guaranteed.
