Description
Das Patent 860 365 bezieht sich auf eine Anordnung zum Übergang von Start-Stopp= auf Synchronbetrieb, bei der die Anlauf- und Sperrschritte der Impulskombination über- die synchronbetriebene Strecke mitübertragen werden und bei der der Synchronverteiler nur einen einzigen Abtastkontakt besitzen kann, und bei der schließlich die Abtast= frequenz der Synchronverteiler über einen besonderen Übertragungsweg übertragen wird.The patent 860 365 relates to an arrangement for the transition from start-stop = to synchronous operation, in which the start-up and blocking steps of the pulse combination are also transmitted over the synchronously operated path and in which the synchronous distributor can only have a single sensing contact, and in which Finally, the sampling frequency of the synchronous distributor is transmitted via a special transmission path.
Andererseits ist es bekannt, Duplexschaltungen für absatzweisen Verkehr (Wechselverkehr) auf Fernleitungen derart auszubilden, daß abhängig von der Betätigung des Sendekontaktes auf einer Station das eigene Empfangsrelais für einen gewissen Zeitraum während der Dauer eines Schrittes unwirksam. gemacht, z. B. kurzgeschlossen wird. Der Zeitraum wird so bemessen, -daß. inzwischen ,der Einschwingvorgang des'. gesendeten Schrittes abgeklungen ist. Deshalb"bräücht bei derartigen Schaltungen die Nachbildung der Duplexschaltung nur in bezug auf den Gleichstrom abgeglichen zu sein, während die kapazitive und induktive Komponente durch den Kurzschluß des Empfangsrelais unwirksam gemacht wird. Diese Schaltungen haben den Nachteil, daß sie nur absatzweisen Verkehr zulassen.On the other hand, it is known to use duplex circuits for batch traffic (Exchange traffic) to train on long-distance lines in such a way that depending on the operation of the send contact on a station its own receive relay for a certain Period ineffective for the duration of a step. made, e.g. B. shorted will. The period is measured in such a way that. meanwhile, the transient process of the '. sent step has subsided. That is why it would be necessary for such circuits the simulation of the duplex circuit is only adjusted with respect to the direct current to be, while the capacitive and inductive component by the short circuit of the Receiving relay is made ineffective. These circuits have the disadvantage that they only allow intermittent traffic.
Synchronbetrieb mit Übertragung der Synchronisierfrequenz nach dem Hauptpatent ermöglicht nun aber bei einer solchen Schaltung den Übergang vom absatzweisen zum vollen Gegenschreibbetrieb, wenn man nur die Phasenverschiebung zwischen den Einsätzen der ausgesendeten Zeichen und den ankommenden Zeichen so legt, daß die Freigabe des Empfangsrelais etwa in der Mitte der empfangenen Schritte erfolgt und Freigabe und Sperrung des Empfangsrelais von der Synchronisierfrequenz gesteuert -,verden.Synchronous operation with transmission of the synchronization frequency after However, the main patent now enables the transition from paragraph-wise to such a circuit to full counter write operation, if only the phase shift between the Inserting the sent characters and the incoming characters so that the The receiving relay is released approximately in the middle of the received steps and Enable and disable the receiving relay controlled by the synchronization frequency -, verden.
Ein Ausführungsbeispiel ist in der Figur dargestellt.An embodiment is shown in the figure.
Vom Telegraphengerät T i kommen die Telegraphierzeichen an und werden einem entzerrenden Übertrager E i zugeführt, der entsprechend der Fig. i des Patentes 860 365 ausgebildet ist und der die vom Teilnehmer T i ausgehenden Springschreiberzeichen auf .die Frequenz von 50 Hz synchronisiert, derart, daß durch den Äbtastkontakt k i das Senderelais SR i im Takte des Synchronismus gesteuert wird. Das Empfangsrelais liegt in einer Brückenschaltung; vorgeschaltet ist ein Netzwerk NPh i, durch dessen Verstellung die Phasenlage zwischen. den Sende- und Empfangszeichen verstellt werden kann. Auf der Sende- und Empfangsseite werden die Kontakte k i und k 2 der entzerrenden .Übertrager F i und E2 in der im Hauptpatent beschriebenen Weise von der gleichen Synehronisierfrequenz von 5o Hz gesteuert, die entweder in irgendeiner Weise über die Leitung übertragen oder aber dem gleichen Wechselstromnetz entnommen wird. Die Empfangsleitung des Teilnehmers T i ist über das Empfangsrelais ER i angeschlossen. Das gleiche gilt für den Teilnehmer T2 und das Empfangsrelais ER 2,. Einem Relais KS i bzw. KS2 wird auch die Abtastfrequenz von 5o Hz zugeführt, so: daß deren Kontakte.ks i und ks2 die Empfangsrelais ER i und ER 2 während bestimmter Zeiträume kurzschließen: Diese Zeiträume werden durch die zweite Wicklung der Relais KS bestimmt.From Telegraph device T i the Telegraphierzeichen arrive and an equalizing exchanger E i are supplied to the corresponding to FIG. Formed i the patent 860,365 and the subscriber-originated T i Spring scribe mark on .the frequency of 50 Hz is synchronized such that the transmission relay SR i is controlled in the cycle of synchronism by the scanning contact ki. The receiving relay is located in a bridge circuit; upstream is a network NPh i, by adjusting the phase position between. the send and receive characters can be adjusted. On the transmitting and receiving side, the contacts ki and k 2 of the equalizing transmitters F i and E2 are controlled in the manner described in the main patent by the same synchronization frequency of 50 Hz, which are either transmitted in some way over the line or the same AC network is removed. The receiving line of the subscriber T i is connected via the receiving relay ER i. The same applies to the subscriber T2 and the receiving relay ER 2 ,. The sampling frequency of 50 Hz is also fed to a relay KS i or KS2 so that their contacts ks i and ks2 short-circuit the receiving relays ER i and ER 2 during certain periods of time: these periods of time are determined by the second winding of the relays KS.
In der Fig.2 ist der Stromverlauf der wichtigsten Teile der Schaltung dargestellt, und zwar zeigt die Linie a beispielsweise die Kontaktgabe des Kontaktes sr i und die Linie b den Empfangsstrom im Relais ER i und die Linie c die Kontaktgabe des Kontaktes ks i. Man erkennt, daß das Empfangsrelais jeweils für die Dauer von etwa So°/o, eines Schrittes nach Beginn des Sendezeichens kurzgeschlossen wird. Da die Kontakte ksi und ks2 von der :Abtastfrequenz gesteuert werden, lassen sich diese Zeitpunkte mit sehr großer Genauigkeit bestimmen und einstellen.In Fig.2 the current curve of the most important parts of the circuit is shown, namely the line a shows, for example, the contact making of the contact sr i and line b the received current in relay ER i and line c the contact of contact ks i. It can be seen that the receiving relay for the duration of is short-circuited about so ° / o, one step after the start of the transmission signal. Since the contacts ksi and ks2 are controlled by the sampling frequency, determine and set these points in time with great accuracy.
