Description

Schaltungsanordnung zur Messung des Verkehrswertes in Fernmelde-, insbesondere Fernsprechanlagen Die Erfindung betrifft eine Schaltungsanordnung zur Messung des Verkehrswertes mittels Erlangmeter in Femmelde-, insbesondere Fernsprechanlagen.Circuit arrangement for measuring the market value in telecommunications, in particular telephone systems The invention relates to a circuit arrangement for Measurement of the market value by means of an Erlangmeter in telecommunication systems, in particular telephone systems.

Um Verkehrsmessungen durchführen zu können, wird üblicherweise auf dem jedem Eingang von Koppelanordnungen zugeordneten Belegungsschaltmittel ein gesonderter Kontakt und ein mit diesem Kontakt in Reihe liegender Widerstand mit einem Wert von 2 k.0- vorgesehen. Die über solche Kontakte und Widerstände fließenden Ströme werden dem Erlangmeter, einem Amperestundenzähler, -schreiber oder -drucker, zugeleitet und bilden ein Maß für die Anzahl gleichzeitiger Belegungen. Diese Methode läßt sich jedoch bei der Koppelfeldtechnik insofern nicht anwenden, als bei dieser Technik Belegungsschaltmittel im bisherigen Sinne nicht immer vorhanden sind.In order to be able to carry out traffic measurements, is usually on a separate occupancy switch associated with each input of coupling arrangements Contact and a resistor in series with this contact with a value from 2 k.0- provided. The currents flowing through such contacts and resistors are sent to the Erlangmeter, an ampere-hour meter, recorder or printer and form a measure of the number of simultaneous occupancies. This method lets however, do not apply to the switching network technology to the extent that they are used with this technology Occupancy switching means in the previous sense are not always available.

Die Aufgabe der Erfindung besteht darin, eine Anordnung zu schaffen, die eine einfache Messung des Verkehrswertes in Koppelfeldern zuläßt. Dies wird gemäß der Erfindung dadurch erreicht, daß dem Erlangmeter in Koppelfeldern die Halteströme der Koppelpunktschaltmittel zuführbar sind. Dabei übernehmen also die Koppelpunktschaltmittel hinsichtlich der Messung des Verkehrswertes die Aufgabe der Belegungsschaltmittel. Grundsätzlich wäre es auch hier möglich, je Koppelpunktschaltmittel einen besonderen Kontakt aufzuwenden. Die Zahl dieser Kontakte wäre aber um ein Vielfaches größer und würde einen erhöhten Raumbedarf des Koppelfeldes zur Folge haben.The object of the invention is to create an arrangement which allows a simple measurement of the traffic value in switching networks. this will according to the invention achieved in that the Erlangmeter in switching networks the holding currents the crosspoint switching means can be supplied. In this case, the crosspoint switching means take over the task of the occupancy switch with regard to the measurement of the market value. In principle, it would also be possible here to have a special one for each crosspoint switching means To spend contact. However, the number of these contacts would be many times greater and would result in an increased space requirement for the switching network.

An Hand eines Ausführungsbeispieles wird die Erfindung näher erläutert.The invention is explained in more detail using an exemplary embodiment.

In der Zeichnung ist ein Koppelfeld KF mit y Eingängen und x Ausgängen auszugsweise dargestellt. Den Eingängen sind die Relais L 1 ... LY und den Ausgängen die Relais Z 1 ... ZX zugeordnet. Bei Ansteuerung eines Eingangs und Ausgangs wird über die entsprechenden Markieradem v und h Erdpotential an die betreffenden Relais L und Z gegeben. Es seien dadurch beispielsweise die Relais L1 und Z2 betätigt worden. über die Kontakte 11, z 21 spricht dann das die Verbindung durchschaltende Koppelpunktrelais K 12 an, welches sich über seinen Kontakt k 12, den Widerstand R 1 und die Ader c 1 nach Rückkehr der Relais L1, Z2 in die Ruhelage hält. In nicht dargestellter Weise wird verhindert, daß ein weiteres Koppelpunktrelais der Spalte K11... KIX betätigt wird, solange nicht das Koppelpunktrelais K12 durch Öffnen der Ader c 1 freigegeben wird. Es kann sich also nur jeweils ein Koppelpunktrelais je Eingang im angesprochenen Zustand befinden. Die Halteströme dieser Koppelpunktrelais werden nun über das Erlangmeter M geführt. Zu diesem Zweck dient das durch die Taste T steuerbare Relais U, welches mit seinem Folgeumschaltekontakt u das Erlangmeter M in die Stromzuführungsleitung der Koppelpunktrelais K einschleift. Der Gesamtwiderstand in jedem Haltestromkreis beträgt vorzugsweise 2 k,Q, damit das übliche Erlangmeter ohne Änderung verwendet werden kann. Dieser Gesamtwiderstand kann aus dem Widerstandswert eines Koppelpunktrelais K allein bestehen; er kann sich aber auch z. B. aus den Widerständen R 1 und K 12 zusammensetzen, wie die Zeichnung zeigt. Die Widerstände R 1 ... RY dienen zur Verringerung der Halteströme. Bei Verwendung von Widerständen R 1... RY mit gegenüber den gebräuchlichen Toleranzen der Koppelpunktrelais engeren Toleranzen läßt sich die Meßgenauigkeit noch erhöhen.The drawing shows extracts of a switching network KF with y inputs and x outputs. Relays L 1 ... LY are assigned to the inputs and relays Z 1 ... ZX to the outputs. When activating an input and output, ground potential is given to the relevant relays L and Z via the corresponding markers v and h. For example, relays L1 and Z2 have been actuated as a result. Via the contacts 11, z 21 then the connection through-switching coupling point relay K 12 responds, which via its contact k 12, the resistor R 1 and the wire c 1 remains in the rest position after the relays L1, Z2 return. In a manner not shown, a further crosspoint relay in column K11 ... KIX is prevented from being actuated as long as crosspoint relay K12 is not released by opening wire c 1. So there can only be one crosspoint relay per input in the addressed state. The holding currents of these crosspoint relays are now conducted via the Erlangmeter M. For this purpose the relay U, which can be controlled by the key T , is used, which with its sequential switchover contact u loops the Erlangmeter M into the power supply line of the crosspoint relay K. The total resistance in each holding circuit is preferably 2 k, Q, so that the usual Erlangmeter can be used without modification. This total resistance can consist of the resistance value of a coupling point relay K alone; but he can also z. B. composed of the resistors R 1 and K 12, as the drawing shows. The resistors R 1 ... RY are used to reduce the holding currents. When using resistors R 1 ... RY with tighter tolerances compared to the usual tolerances of the coupling point relays, the measuring accuracy can be increased even further.
