Es sind Einrichtungen zur Signalübertragung von Zügen bekannt, bei welchen auf einer Lokomotive ein Wechselstromgenerator aufgestellt wird, der über einen Streckenstromkreis einen ebenfalls auf der Lokomotive befindlichen Empfänger beeinflußt.There are devices for signal transmission from trains known in which on a locomotive an alternator is set up, which has a also affects the receiver located on the locomotive.
Diese Schaltung besitzt einen gewissen praktischen Vorteil. Der Empfangskreis kann nämlich durch metallische Teile der Strecke nicht beeinflußt werden, so daß bei anderen Einrichtungen dadurch verursachte Fehlauslösungen hier nicht stattfinden können. Diesen Nachteil besitzen in gewissem Grade z. B. induktive Einrichtungen, bei denen Stromänderungen eines elektromagnetisch von der Strecke aus beeinflußten Lokomotivstromkreises zur Signalgebung benutzt werden. Nähert man bei diesenAnordnungen dem Lokomotivmagneten einen metallischen Körper, so ändert sich der Widerstand des Lokomotivmagneten und damit der Lokomotivstrom. Je nach dem Grade der Störung kann die entsprechende Stromänderung das Signalrelais zur Auslösung bringen. Die Stromänderung wird um so größer sein, wenn man den Lokomotivstromkreis in Resonanz schaltet, in welchem Falle ja verhältnismäßig geringe Änderungen des induktiven Widerstandes des Lokomotivmagneten verhältnismäßig große Stromänderungen zur Folge haben können.This circuit has some practical advantage. The receiving circle can namely are not influenced by metallic parts of the route, so that with others Incorrect tripping caused by facilities cannot take place here. This one Disadvantage have to a certain extent z. B. inductive devices where current changes a locomotive circuit that is electromagnetically influenced by the route can be used for signaling. If you approach With these arrangements the locomotive magnet has a metallic body, so the changes Resistance of the locomotive magnet and thus the locomotive current. Depending on the degree of Fault, the corresponding change in current can trigger the signal relay. the Current change will be all the greater if you put the locomotive circuit in resonance switches, in which case relatively small changes in the inductive resistance of the locomotive magnet can result in relatively large changes in current.
Bei derartigen Einrichtungen muß also auf die Möglichkeit von Fehlauslösungen durch gewisse Gleisanordnungen (z. B. Eisenanordnungen be Bauarbeiten an Brücken u. dgl.) Rücksicht genommen werden. Die zuerst erwähnte, von derartigen Schwierigkeiten freie Schaltungsanordnung hat aber den Nachteil, daß der Empfangskreis im Ruhezustand nicht stromdurchflossen ist, seine Ansprechfähigkeit also nicht dauernd überprüft wird. Dieses ist wahrscheinlich der Grund, warum sich die Anordnung nicht in den Betrieb hat einführen lassen. Im Sinne der vorliegenden Erfindung wird der Nachteil dadurch vermieden, daß dem Empfangskreis zu Prüfzwecken eine besondere elektromotorische Kraft dauernd aufgedrückt wird, durch die ein Ruhestrom zur Überwachung des Empfangskreises hervorgerufen wird. Ein entsprechendes Schaltungsbeispiel ist auf der Zeichnung dargestellt. In der Abbildung ist •mit G der Wechselstromgenerator der Lokomotive, mit Lx der Senderwechselstrommagnet, mit L4 der empfangende Wechselstrommagnet bezeichnet. L1 und L4 sind auf der Lokomotive in ihrem Fahrgestell angeordnet, mit offener magnetischer Streuung nach dem Gleiskörper. Der Empfängermagnet L4 der Lokomotive ist an ein Relais R angeschaltet. Der so gebildete Empfangsstromkreis III wird von der elektromotorischen Kraft E dauernd erregt. Auf der Strecke sind zwei Magnete L2 und La angeordnet mit einer den beiden Lokomotivmagneten entsprechenden gegenseitigen Lage. Der Sende-In the case of such devices, the possibility of false tripping due to certain track arrangements (e.g. iron arrangements during construction work on bridges, etc.) must be taken into account. The first-mentioned circuit arrangement, free of such difficulties, has the disadvantage that the receiving circuit does not have current flowing through it in the idle state, so that its responsiveness is not continuously checked. This is probably the reason why the arrangement could not be introduced into operation. In the context of the present invention, the disadvantage is avoided in that a special electromotive force is continuously impressed on the receiving circuit for testing purposes, by means of which a quiescent current is produced for monitoring the receiving circuit. A corresponding circuit example is shown in the drawing. In the illustration • G is the alternator of the locomotive, L x is the transmitter alternating current magnet, and L 4 is the receiving alternating current magnet. L 1 and L 4 are arranged on the locomotive in its chassis, with open magnetic scattering after the track structure. The receiver magnet L 4 of the locomotive is connected to a relay R. The receiving circuit III formed in this way is continuously excited by the electromotive force E. Two magnets L 2 and L a are arranged on the route with a mutual position corresponding to the two locomotive magnets. The broadcast

lokomotivmagnet L1 wirkt normalerweise nicht auf den Empfängermagneten Z4. Eine Beeinflussung findet erst statt, wenn die Lokomotive über die Streckenmagnete hinwegfährt. 5 Obwohl man z. B. auch Gleichspannung aus der Beleuchtungsturbine der Lokomotive als Stromquelle für den Empfangskreis benutzen könnte, wählt man doch zweckmäßig den Signalwechselstromgenerator G selbst dazu, daeinevollkommen einwandfreie Ruhestromüberwachung nur durch die Signalfrequenz selbst gewährleistet wird.Locomotive magnet L 1 does not normally act on the receiver magnet Z 4 . An influence only takes place when the locomotive drives over the track magnets. 5 Although one z. B. could also use DC voltage from the lighting turbine of the locomotive as a power source for the receiving circuit, but it is appropriate to choose the signal alternating current generator G itself, since a completely perfect closed-circuit current monitoring is only guaranteed by the signal frequency itself.
Die im Empfangskreis wirkende EMK wählt man dann zweckmäßig durch geeignete Anschaltung an Generator G in ihrer Amplitude und Phase derart, daß bei Streckenwirkung der Strom im Empfangskreis verschwindet. Um größere Änderungen der aus dem Streckenkreis II in dem Empfangskreis II induzierten Spannung im Betrieb zu vermeiden, empfiehlt sich die Verwendung möglichst geringer Kopplungen UT1 und K2 zwischen den Magneten L1, L2 bzw. L3, L1. The EMF acting in the receiving circuit is then expediently selected by suitable connection to generator G in terms of its amplitude and phase in such a way that the current in the receiving circuit disappears when the path acts. In order to avoid major changes in the voltage induced from the section circuit II in the receiving circuit II during operation, it is advisable to use the lowest possible couplings UT 1 and K 2 between the magnets L 1 , L 2 or L 3 , L 1 .
Die im Empfangskreis induzierte Spannung kann durch Resonanzschaltung in den verschiedenen Stromkreisen erhöht werden. Schaltet man auch den Empfangskreis in Resonanz, so wird man die Kopplung K2 um so geringer wählen müssen, um Ruhestromschwankungen durch Streckeneinflüsse zu vermeiden.The voltage induced in the receiving circuit can be increased by resonance switching in the various circuits. If the receiving circuit is also switched to resonance, then the coupling K 2 will have to be selected so that it is less so in order to avoid fluctuations in quiescent current due to line influences.
Die Relaisanordnung kann entweder je nach der Höhe der Frequenz aus einem gewöhnlichen eisengeschlossenen oder dynamometrischen Relais, aber auch aus Elektronen- oder Gas- und Gleichstromrelais mit oder ohne Verstärkung bestehen. Zur Ruhestromüberwachung und zur Signalübertragung können natürlich auch getrennteRelaisanordnungenVerwendungfinden. Die Überwachungsrelaisanordnung braucht dann nicht mehr hohe Ansprechgeschwindigkeit zu besitzen, so daß für ihren Betrieb auch entsprechend geringe, der vorher genannten Amplitudenbedingung nicht mehr genügende Überwachungsspannungen benutzt werden können.The relay arrangement can either be an ordinary one depending on the level of frequency iron-closed or dynamometric relays, but also made of electron or gas and DC relays exist with or without amplification. For closed-circuit monitoring and Separate relay arrangements can of course also be used for signal transmission. The monitoring relay arrangement then no longer needs a high response speed have, so that the amplitude condition mentioned above is also correspondingly low for their operation Monitoring voltages that are no longer sufficient can no longer be used.
Der Senderstromkreis I wird zweckmäßig ebenfalls mit einer Ruhestromüberwachung auszustatten sein.The transmitter circuit I is also expediently equipped with a closed-circuit current monitor be.
