Description

Auf dem Gebiet der Fernmeßtechnik, also der elektrischen Übertragung von Anzeigen über Drucke, Durchflußmengen, Temperaturen usw., werden Verfahren angewandt, bei welchen der Meßwert in kontinuierliche elektrische Stromstöße umgewandelt wird, deren Zahl je Zeiteinheit sich mit der Höhe des Meßwertes ändert. Die Frequenz dieser Stromstöße bewirkt auf der Empfangsseite der Fernmeßanlage die Einstellung des dortigen Anzeigegerätes auf den jeweiligen Meßwert.In the field of telemetry, i.e. electrical transmission of indications about pressures, flow rates, temperatures etc., methods are used in which the measured value is converted into continuous electrical current surges, the number of which per unit of time changes with the level of the measured value. The frequency of this Current surges on the receiving side of the telemetry system cause the local to be set Display device to the respective measured value.

Auf der Sendeseite von Anlagen dieser Art ist das wichtigste Organ die Impulsgebevorrichtung, auch Sendezähler genannt, die durch ihre größere oder kleinere Umlaufgeschwindigkeit die Frequenz der kontinuierlichen Stromstöße in Richtung auf die Empfängerseite verändert. Die übliche Ausführung dieser Impulsgebevorrichtung (Sendezähler) sieht einen Kollektor mit darauf schleifenden Bürsten vor. Dieser Kollektor ist derart in Lamellen aufgeteilt, daß bei seiner Drehung abwechselnd eine elektrische Verbindung zwischen den beiden schleifenden Bürsten hergestellt und unterbrochen wird. Diese Ausführung besitzt, wie die Erfahrung bewiesen hat, den Fehler, daß durch mechanische Abnutzung von Bürsten und Kollektorlamellen die völlige Unterbrechung des Stromflusses ausbleibt und daher die für richtige Fernübertragung der Meßwerte notwendige saubere Impulsfolge gestört wird. Es sind viele Vorschläge gemacht worden, durch Änderung der Werkstoffe der Bürsten und Kollektoren oder Änderungen der Konstruktion der Kollektoren die Beanstandungen zu beheben. Das Prinzip der auf Kollektoren gleitenden Bürsten ist aber bei diesen Vorschlägen stets beibehalten worden. Alle diese Vorschläge haben zu keinem Erfolg geführt.On the sending side of this type of equipment is the most important organ the pulse generating device, also called the transmission counter, which by their larger or lower orbital velocity the frequency of continuous current surges towards changed to the receiving end. The usual design of this pulse generator (Send counter) provides a collector with brushes sliding on it. This The collector is divided into lamellae in such a way that it rotates alternately an electrical connection is established between the two grinding brushes and is interrupted. As experience has shown, this version has the mistake that through mechanical wear and tear of brushes and collector lamellas the there is no complete interruption of the current flow and therefore the necessary for correct long-distance transmission the necessary clean pulse sequence is disturbed. There are many suggestions has been made by changing the materials of the brushes and collectors or changes the construction of the collectors to resolve the complaints. The principle of Brushes sliding on collectors, however, are always retained in these proposals been. None of these proposals have resulted in success.

Es hat sich nun überraschenderweise gezeigt, daß die Nachteile der bekannten kontinuierlich registrierenden Fernmeßanlagen vermieden werden, wenn statt der Impulsgeber mit den auf Kollektoren schleifenden Kontaktbürsten Impulsgeber verwendet werden, bei denen die Kontakte nicht aufeinander schleifen, sondern voneinander abgehoben werden, wie dies im Prinzip bei den Impulsgebern der Fernsprecher mit Wählerscheibe der Fall ist.It has now been shown, surprisingly, that the disadvantages of known continuously registering telemetry systems are avoided if instead the pulse generator with the contact brushes that slide on the collectors can be used in which the contacts do not slide against each other, but against each other can be picked up, as in principle with the pulse generators of the telephone Voter disc is the case.

Gemä4 der Erfindung wird däher bei kontinuierlich registrierenden Fernmeßanlagen die Impulsgebevorrichtung aus den Sendestromkreis schließenden, aneinanderliegenden Kontaktfedern und, im Gegensatz zu den Impulsgebern der bekannten Fernsprecher mit Wählerscheibe, einem zwischen den Kontaktfedern kontinuierlich umlaufenden Rad gebildet, das so ausgebildet ist, daß es bei einer Umdrehung die Kontaktfedern ein oder mehrere Male voneinander trennt und dadurch jeweils den Sendestromkreis unterbricht. Je nach der Umlaufgeschwindigkeit des Rades wiederholt sich dieser Vorgang schneller oder langsamer, und die Zahl der gegebenen Stromimpulse in Richtung auf den Empfänger ändert sich dementsprechend.According to the invention, it is used with continuously registering Telemetry systems, the pulse generating device from the transmission circuit closing, contiguous Contact springs and, in contrast to the pulse generators of the well-known telephones with Selector disk, a continuously rotating wheel formed between the contact springs, which is designed so that it the contact springs one or more with one revolution Times separates from each other and thereby interrupts the transmission circuit. Ever this process is repeated more quickly after the speed of rotation of the wheel or slower, and the number of current pulses given in the direction of the receiver changes accordingly.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, und zwar zeigt Fig. i eine Ansicht von oben, Fig.2 eine Seitenansicht einer Impulsgebevorrichtung im Zustand der Trennung des Sendestromkreises.An embodiment of the invention is shown in the drawing, namely, FIG. 1 shows a view from above, FIG. 2 shows a side view of a pulse generating device in the state of separation of the transmission circuit.

Mit i sind die im Sendestromkreis liegenden Kontaktfedern bezeichnet, die mit ihren Kontaktspitzen :2 sich berühren. Zwischen diesen liegt das umlaufende Rad 3, dessen Drehzahl von der Höhe des zu übermittelnden Meßwertes abhängig ist. Das Rad 3 besitzt Zacken 4, die bei ihrem Durchgang durch die Kontaktfedern i diese auseinanderbiegen und die Kontaktspitzen 2 trennen. Nach ihrem Durchgang lassen sie die Kontaktfedern wieder mit ihren Kontaktspitzen 2 sich berühren.The contact springs in the transmission circuit are denoted by i, those with their contact tips: 2 touch. Between these lies the circulating one Wheel 3, the speed of which depends on the level of the measured value to be transmitted. The wheel 3 has teeth 4, which when they pass through the contact springs i these Bend it apart and separate the contact tips 2. Let after their passage they touch the contact springs again with their contact tips 2.

Die Zacken ,4 sind nicht stromleitend, so daß sie bei ihrem Durchgang durch die Kontaktfedern i den Sendestromkreis unterbrechen. Je schneller das Rad 3 umläuft, desto öfter wird der Sendestromkreis unterbrochen.The prongs, 4 are not conductive, so that they do so when they pass interrupt the transmission circuit through the contact springs i. The faster the wheel 3 rotates, the more often the transmission circuit is interrupted.
