Description

Fernmeßgerät, insbesondere registrierendes Instrument, für den Empfang von der zu messenden Größe in ihrer Zeitdauer proportionalen Impulsen Als Empfangsinstrument für das Impulszeitfernmeßsystem, bei welchem Stromstöße, deren Dauer den zu übertragenden Meßgrößen proportional ist, fernübertragen werden, ist eine Einrichtung bekannt geworden, welche im wesentlichen aus drei Teilen besteht. Jeder dieser Teile steht unter dem Einfluß einer Spiralfeder und arbeitet mit den übrigen derart zusammen, daß der Zeiger des Empfangsinstrumentes sich bei jedem Impuls nur um die Differenz gegenüber dem vorhergehenden Impuls bewegt. Eine andere Einrichtung, welche ebenfalls dazu dient, den Zeiger bei jedem Impuls nur um die Differenz gegenüber dem vorher übertragenen zu bewegen, besitzt einen Rückführmitnehmer, welcher nach Beendigung eines Impulses mit dem Antriebsmotor des Instrumentes gekuppelt wird und die Zurückstellung des Zeigers auf den gerade übertragenen Wert bewirkt, soweit dies nicht schon während der Dauer des Impulses geschehen ist.Telemetry device, in particular a recording instrument, for reception impulses proportional to the duration of the quantity to be measured As a receiving instrument for the pulse time telemetry system, in which current surges, the duration of which is to be transmitted Measured quantities is proportional to be transmitted remotely, a device is known which essentially consists of three parts. Each of these parts stands under the influence of a spiral spring and cooperates with the rest in such a way that that the pointer of the receiving instrument is only about the difference with each impulse moved compared to the previous pulse. Another facility, which too serves to adjust the pointer with each pulse only by the difference compared to the previous one to move transferred, has a return driver, which after completion a pulse is coupled to the drive motor of the instrument and the reset of the pointer to the value just transferred, unless this has already occurred during the duration of the impulse has happened.

Durch die vorliegende Erfindung wird ein bei weitem einfacheres Empfangsinstrument für das Impulszeitfernmeßsystem geschaffen. Das neue Instrument enthält nur zwei Bestandteile und arbeitet erfindungsgemäß in der Weise, daß@ ein von den Zeitimpulsen betätigter und die Kupplung des ersten Teiles mit dem Antriebsmotor bewirkender Elektromagnet seinen Anker mit derartiger Verzögerung bewegt, daß nach Beendigung eines Zeitimpulses der während dessen Dauer bewegte erste Teil erst wieder in seine Nullage zurückfällt. nachdem die zur Nachstellung des mit dem Ablesezeiger verbundenen zweiten Teiles dienenden Einstellmittel betätigt worden sind.The present invention provides a far simpler receiving instrument created for the pulse time telemetry system. The new instrument contains only two Components and works according to the invention in such a way that @ one of the time pulses actuated and causing the coupling of the first part with the drive motor Electromagnet moves its armature with such a delay that after termination of a time pulse, the first part moved during its duration only returns to its Zero position falls back. after the readjustment of the associated with the reading pointer second part serving adjustment means have been actuated.

Ein Ausführungsbeispiel ist im folgenden beschrieben und in der Zeichnung schematisch dargestellt. Es bezieht sich auf ein Registrierinstrument, bei welchem die Schreibfeder mit dem ersten Teil des Empfangsinstrumentes und die zur visuellen Ablesung derAugenblickswerte derMeßgrögen dienende Zeigerspitze mit dem zweiten Teil verbunden ist. Der Registrierstreifen zeigt dementsprechend eine Anzahl von parallelen Strichen, deren Länge den einzelnen Stromimpulsen und damit den Meßwerten entspricht. Mit i ist das Registrieipapier, mit a der Zeiger mit Schreibfeder, mit 3 ein Synchronmotor bezeichnet. 4 stellt den Ablesezeiger mit Skala dar, 5 und 6 sind Relais. Das Empfangsrelais mit Arbeits- und Ruhekontakt ist mit 7 bezeichnet. Die Wirkungsweise der Einrichtung ist die folgende: Die in der Zeichnung angenommene Stellung der Apparatur entspricht einem Zeitpunkt zwischen zwei Stromimpulsen. Wenn ein Stromimpuls beginnt, schließt das an der Fernleitung liegende Relais 7 seinen Arbeitskontakt und erregt damit das Kupplungsrelais 5. Dadurch wird der Synchronmotor 3 mittels der Stirnzahnradkupplung 8 mit der Fadenrolle 9, d. h. mit dem Zeiger 2, gekuppelt und dieser während der Dauer des Impulses mit konstanter Geschwindigkeit bewegt. Die Strichlänge auf dem Registrierpapier ist dabei proportional der Meßgröße. Soweit entspricht die Anordnung einem reinen Registrierinstrument. Nach Beendigung des Stromimpulses bleibt der Registrierzeiger 2 für kurze Zeit in seiner Lage, da das Kupplungsrelais 5 verzögert abfällt, und das Relais 6, das zur Neueinstellung des Ablesezeigers 4 dient, tritt in Tätigkeit. Es wird über den Ruhekontakt des Empfangsrelais 7 erregt und lüftet beim Anziehen seines Ankers kurzzeitig den Bremsklotz i i. Wenn der neue Impuls kürzer ist als der vorhergehende, wird der Zeiger 4 durch das Gewicht 12 auf den neuen kleineren Ausschlag zurückbewegt. Wenn der vorhergehende Impuls -kürzer war, nimmt der Registrierzeiger den Ablesezeiger schon während des Stromimpulses in die neue Stellung mit. Beim Beginn eines neuen Stromimpulses wird der Anker i o losgelassen, aber der Bremsklotz i i nicht betätigt.An exemplary embodiment is described below and in the drawing shown schematically. It refers to a registration instrument in which the pen with the first part of the receiving instrument and the one for the visual Reading the instantaneous values of the measurands with the second pointer tip Part is connected. The register strip accordingly shows a number of parallel lines, the length of which corresponds to the individual current pulses and thus the measured values is equivalent to. With i is the recording paper, with a the pointer with pen, with 3 denotes a synchronous motor. 4 represents the reading pointer with scale , 5 and 6 are relays. The receiving relay with make and break contact is with 7 designated. The operation of the device is as follows: The one in the drawing The assumed position of the apparatus corresponds to a point in time between two current pulses. When a current pulse begins, the relay 7 on the long-distance line closes its normally open contact and thus energizes the clutch relay 5. This makes the synchronous motor 3 by means of the spur gear coupling 8 with the thread roller 9, d. H. with the pointer 2, coupled and this at constant speed for the duration of the pulse emotional. The line length on the recording paper is proportional to the measured variable. So far the arrangement corresponds to a pure recording instrument. After completion of the current pulse, the registration pointer 2 remains in its position for a short time, there the clutch relay 5 drops delayed, and the relay 6, the readjustment of the reading pointer 4 is used. It is via the normally closed contact of the Receiving relay 7 energizes and briefly releases the brake pad when its armature is tightened i i. If the new pulse is shorter than the previous one, the pointer 4 is through the weight 12 moved back to the new smaller deflection. If the previous Pulse was shorter, the registration pointer takes the reading pointer during the Current pulse in the new position with. At the beginning of a new current pulse the anchor i o released, but the brake pad i i not actuated.
