Das Hauptpatent betrifft eine Fernwirkanlage zur zentralen Überwachung und Fehlerortung in Trägerfrequenz-Weitverkehrssystemen mit vielen, insbesondere oberirdischen Hauptämtern und von diesen ferngespeisten, insbesondere unterirdischen Zwischenverstärkern, bei der von einer Zentrale aus der Betriebszustand des Übertragungssystems überwacht wird und ein Fehler entweder in einem Hauptamt oder einem Abschnitt zwischen zwei Hauptämtern lokalisiert wird und außerdem die Fehlerart bestimmt wird, wobei von der Zentrale über das zur trägerfrequenten Übertragung in abgehender Richtung dienende Leitungspaar oder über eine Beipackdoppelleitung nacheinander einzelne Fernüberwachungsimpulse ausgesendet werden, die in jedem Hauptamt empfangen werden und dort einen an sich bekannten, irreversiblen, «-stufigen, binären Empfangszähler betätigen, der nach dem Empfang der entsprechenden Fernüberwachungsimpulse Stelltransistoren anregt, die das Zurücksenden eines mit Hilfe des Empfangs-Zählers binär codierten Rückmeldesignals über das zur trägerfrequenten Übertragung in ankommender Richtung dienende Leitungspaar oder eine Beipackdoppelleitung zur Zentrale veranlassen, wo festgestellt wird, welches Amt beim Ansteuern kein Rückmeidesignal oder ein besonders gekennzeichnetes Rückmeldesignal zurückgesendet hat.The main patent relates to a telecontrol system for central monitoring and fault location in long-distance carrier frequency systems with many, especially above-ground main offices and remote-fed from them, in particular underground repeaters, in the case of which the operating status is taken from a control center of the transmission system is monitored and an error either in a main office or a section between two main offices and also determines the type of error is, from the control center via the carrier-frequency transmission in the outgoing direction A pair of lines or a pair of additional lines, individual remote monitoring impulses are sent out one after the other, in each main office are received and there actuate a known, irreversible, «-stage, binary receive counter, which excites control transistors after receiving the corresponding remote monitoring pulses, which sends back a feedback signal that is binary-coded with the help of the receive counter via the Line pair used for carrier-frequency transmission in the incoming direction or an additional double line to the control center, where it is determined which office does not trigger a return signal or has sent back a specially marked feedback signal.
In der Zentrale ist ein Rückmeldesignalempfänger vorhanden, der unter anderem kontrolliert, ob das gewünschte, abgefragte Amt geantwortet hat. Hierzu ist ein η-stufiger Vergleichszähler, der gleich den in den Hauptämtern vorhandenen Empfangszählern aufgebaut ist und von den ausgesendeten Fernüberwachungsimpulsen betätigt wird, vorgesehen, der die gleiche Stellung hat, wie sie der gerade rückgemeldete Empfangszähler haben sollte. Außerdem werden beim Empfang des Rückmeldesignals η Flip-Flops dem Rückmeldesignal entsprechend eingestellt. Mit Hilfe einer /i-teiligen Koinzidenz-Vergleichsmatrix, die im Hauptpatent als Diodentore Te bezeichnet ist, wird festgestellt, ob die η Flip-Flops dieselbe Stellung wie der Vergleichszähler haben.A feedback signal receiver is available in the control center, which, among other things, checks whether the requested, queried office has answered. For this purpose, an η-level comparison counter is provided, which is constructed like the receive counters in the main offices and is actuated by the remote monitoring pulses sent, which has the same position as the receive counter that has just been reported back should have. In addition, when the feedback signal η is received, flip-flops are set according to the feedback signal. With the aid of a / i-part coincidence comparison matrix, which is referred to in the main patent as diode gates Te , it is determined whether the η flip-flops have the same position as the comparison counter.
Nach dem Hauptpatent enthält jedes Element der Koinzidenz-Vergleichsmatrix einen Differentialübertrager
mit zwei gleichen Primärwicklungen, zwei Impulstore, die paarweise von den zugehörigen
koinzidierenden Flip-Flops und denen des Vergleichszählers an zwei Steuerklemmen gesteuert werden, und
eine Sekundärwicklung. Die Primärwicklungen der Differentialübertrager sind über die zwei zugehörigen
Impulstore an den Ausgang eines Monovibrators geschaltet. Nach dem Empfang des Rückmeldesignals
Fernwirkanlage zur zentralen Überwachung und
Fehlerortung in Trägerfrequenz-Weitverkehrssystemen According to the main patent, each element of the coincidence comparison matrix contains a differential transformer with two identical primary windings, two pulse gates which are controlled in pairs by the associated coinciding flip-flops and those of the comparison counter at two control terminals, and a secondary winding. The primary windings of the differential transformers are connected to the output of a monovibrator via the two associated impulse gates. After receiving the feedback signal, telecontrol system for central monitoring and

kippt der Monovibrator um und liefert einen Impuls in die Koinzidenz-Vergleichsmatrix. Ist Koinzidenz vorhanden, so sind die Impulstore eines jeden Elements entweder beide gesperrt oder beide durchlässig, und an beiden Wicklungen eines jeden Differentialübertragers entstehen gleiche Impulsspannungen, deren Wirkungen sich aufheben. Tritt infolge eines Fehlers keine Koinzidenz zwischen den η Flip-Flops und den Flip-Flops des Vergleichszählers auf, so entsteht in irgendeiner Primärwicklung der Differentialübertrager eine Impulsspannung, die nicht durch eine gleiche Impulsspannung in der zugehörigen Wicklung kompensiert wird. In der zugehörigen Sekundärwicklung entsteht ein Impuls, der einen Alarm-Bivibrator anregt.the monovibrator tips over and delivers a pulse to the coincidence comparison matrix. If there is coincidence, the impulse gates of each element are either both blocked or both permeable, and the same impulse voltages arise on both windings of every differential transformer, the effects of which cancel each other out. If, as a result of an error, there is no coincidence between the η flip-flops and the flip-flops of the comparison counter, a pulse voltage arises in some primary winding of the differential transformer, which is not compensated for by the same pulse voltage in the associated winding. A pulse is generated in the associated secondary winding, which stimulates an alarm bivibrator.
Diese Schaltung hat folgende Nachteile: Der Aufwand der Differentialübertrager ist zu groß. Es muß auf Symmetrie der Differentialübertrager geachtet werden. Die Sekundärimpulse müssen gleichgerichtet werden, weil sie beliebige Polarität haben können.This circuit has the following disadvantages: The complexity of the differential transformer is too great. It must the symmetry of the differential transformer must be ensured. The secondary pulses must be rectified because they can have any polarity.
Die Koinzidenz-Vergleichsmatrix nach der Erfindung, die diese Nachteile vermeidet, ist erfindungsgemäß dadurch gekennzeichnet, daß die η Elemente der Koinzidenz-Vergleichsmatrix aus zwei Impulstoren, die jeweils an zwei Klemmen gesteuert werden, bestehen, daß das eine Impulstor in »Oder«-Schaltung betrieben wird und durchlässig ist, wenn an eine der beiden Steuerklemmen niedriges Potential angelegt wird, daß das andere Impulstor in »Und«-Schaltung betrieben wird und durchlässig ist, wenn an beide Steuerklemmen niedriges Potential angelegt wird, undThe coincidence comparison matrix according to the invention, which avoids these disadvantages, is characterized according to the invention in that the η elements of the coincidence comparison matrix consist of two pulse ports, each controlled at two terminals, that one pulse port in "or" circuit is operated and is permeable when a low potential is applied to one of the two control terminals, that the other impulse gate is operated in an "and" circuit and is permeable when low potential is applied to both control terminals, and
