Description

Vorrichtung zum Fernmessen von Drehgeschwindigkeiten Es ist bekannt, die Drehzahl eines Zählers durch Stromstöße auf ein entferntes Meßgerät, z. B. Strommesser, derart wirken zu lassen, daß der Ausschlag des Meßgerätes die jeweilige Geschwindigkeit des Zählers, also die Ampere- oder Wattzahl, angibt. Die Ausführung erfordert einen Unterbrecher, zweckmäßig eine Kontaktgabe auf der Achse des Zählers mit mehreren Unterbrechungen für jede Umdrehung, die im Stromkreis der Fernleitung liegt, und auf der Empfangsstelle eine 'Stromquelle, die bei jeder Kontaktgabe einen Stromstoß konstanter Stärke in das Anzeigegerät schickt. Der Ausschlag gibt dann den Mittelwert der Geschwindigkeit in der Kontaktgabe. (Natürlich könnte auch ein Zähler die Stromstöße aufnehmen und gleiche Angaben wie der gebende Zähler machen.) Für die Übertragung einer Leistung ist diese Methode in der geschilderten Ausführung nicht brauchbar, wenn es sich nicht nur um die Größe, sondern auch das Vorzeichen der Leistung handelt, da gleiche Leistungen verschiedenen Vorzeichens auf der Empfangsstation denselben Ausschlag hervorrufen würden.Apparatus for telemetry of rotational speeds It is known the speed of a meter by power surges on a remote measuring device, e.g. B. Ammeter, to act in such a way that the deflection of the measuring device the respective speed of the meter, i.e. the number of amperes or watts. It requires one to run Interrupter, expediently a contact on the axis of the counter with several Breaks for each revolution in the power line circuit, and on the receiving point a 'power source, which with each contact is a current impulse Sends constant strength in the display device. The deflection then gives the mean value the speed in making contact. (Of course, a counter could also monitor the power surges record and provide the same information as the supplying counter.) For the transfer This method cannot be used for a service as described, if it is not only about the size, but also the sign of the performance, since the same services with different signs are the same at the receiving station Would cause a rash.

Dieser- Mangel soll gemäß der Erfindung beseitigt werden. Zu diesem Zweck werden folgende Maßnahmen zugleich angewendet: i. Die Übertragung findet nach dem Impulsfrequenzverfahren statt. 2. Die Impulsfrequenz setzt sich aus der arithmetischen Summe einer konstanten Frequenz und einer der zu übertragenden Drehgeschwindigkeit proportionalen Frequenz zusammen.This deficiency is to be eliminated according to the invention. To this Purpose, the following measures are applied at the same time: i. The transfer takes place after the pulse frequency method instead. 2. The pulse frequency is made up of the arithmetic Sum of a constant frequency and one of the rotational speeds to be transmitted proportional frequency together.

3. Als Empfangsgerät dient ein Zeigergerät. Die Abb. i zeigt das Verhältnis zwischen Ausschlag und Skala an der Empfangsstation. Der maximale Ausschlag der Skala ist z. B. 7. Im Sinne des positiven Ausschlages ist zu der Drehzahl des gebenden Zählers eine Drehzahl entsprechend dem Ausschlag io hinzugefügt, so daß sich die übertragenen Ausschläge zwischen den Größen 3 und 17 gleichen Vorzeichens bewegen. Verbrauchte Leistung möge eine positive Drehrichtung des Zählers geben, dann wird der Ausschlag am Empfänger größer als io sein. Bei umgekehrter Drehrichtung des Zählers wird der Ausschlag am Empfänger kleiner als io. Der Nullpunkt der Skala ist für den Ausschlag io festgesetzt, so daß auf der Skala die vom gebenden Zähler aufgenommene oder abgegebene Leistung mit dem richtigen Vorzeichen erscheint.3. A pointing device serves as the receiving device. Fig. I shows the relationship between deflection and scale at the receiving station. The maximum deflection of the Scale is z. B. 7. In the sense of the positive deflection is to the speed of the giving Counter added a speed corresponding to the deflection io, so that the move the transferred deflections between sizes 3 and 17 with the same sign. Consumed power may give a positive direction of rotation of the counter, then will the rash on the recipient is greater than io. If the direction of rotation of the Counter, the deflection on the receiver is less than io. The zero point of the scale is set for the deflection io, so that on the scale that of the giving counter Consumed or delivered power appears with the correct sign.

Ein Ausführungsbeispiel zu einer Einrichtung gemäß der Erfindung zeigt in schematischer Darstellung die Abb. 2. Links ist ein Energiezähler i angedeutet, rechts eine Vorrichtung 2 zur Erzeugung einer konstanten Drehzahl, die als Ferrarisgerät angedeutet ist, aber auch durch ein Uhrwerk ersetzt werden könnte. Die Achsen beider arbeiten mit Hilfe der Kegelräder 3 bis 8 auf ein Planetenrad g. Das Planetengetriebe ist derartig angeordnet bzw. der Drehsinn des Zeitzählers 2 derart gewählt, daß bei dem gewünschten Vorzeichen der Energie die Geschwindigkeiten der beiden Achsen des Energiezählers i und des Zeitzählers 2 als Summe in der Umdrehung des Planetenrades g um die Achse io zum Vorschein kommen und bei umgekehrter Richtung der Energie als Differenz. Die Achse io der Bahn des Planetenrades trägt bei ii den Unterbrecher, die Kontaktscheibe, die in bekannter Weise eine bestimmte Anzahl Stromstöße pro Sekunde bei einer bestimmten Drehgeschwindigkeit der Achse io in die Fernleitung sendet. Die Achse der Räder 6, 8 ist hohl gedacht, um die Achse io hindurchzuführen.An embodiment of a device according to the invention shows Fig. 2 is a schematic representation. On the left, an energy meter i is indicated, on the right a device 2 for generating a constant speed, which is used as a Ferrari device is indicated, but can also be replaced by a clockwork could. The axes of both work with the help of the bevel gears 3 to 8 on a planet gear G. The planetary gear is arranged in this way or the direction of rotation of the time counter 2 chosen such that the velocities of the two axes of the energy meter i and the time meter 2 as a sum in the revolution of the planetary gear g come to the fore around the axis io and in the opposite direction of energy as a difference. The axis io of the path of the planetary gear contributes ii the breaker, the contact disc, which in a known manner a certain number Current surges per second at a certain rotational speed of the axis io in the trunk transmits. The axis of the wheels 6, 8 is thought to be hollow, around the axis pass io.

Im vorstehenden ist eine Anordnung beschrieben, wie zu der Drehzahl des Energiezählers eine konstante Drehzahl addiert wird. Man könnte dieselbe Wirkung aber auch hervorrufen, wenn man in geeigneter Kupplung auf die Achse des Energiezählers i ein zusätzliches konstantes Drehmoment wirken ließe oder indem. man die bisher als ruhend angenommenen Kontaktbürsten in umgekehrter Richtung umlaufen läßt wie die Kontaktscheibe, die vom Zähler mitgenommen wird.In the above, an arrangement is described as to the rotational speed of the energy meter a constant speed is added. You could have the same effect but also cause if one uses a suitable coupling on the axis of the energy meter i would let an additional constant torque act or by. one so far contact brushes assumed to be at rest can rotate in the opposite direction as the contact disc that is taken away by the meter.
