Description

Tonfrequenzfernsteueranlage mit einem zentralen Sender und Tochtersendern mit Rückmeldeeinrichtungen zum zentralen Sender Bei Fernsteuerungsanlagen werden oft verschiedene, gegebenenfalls voneinander getrennte Netzabschnitte von .einem Sender zentral über einen Tochtersender gesteuert. Es ist erwünscht, Rückmeldungen von den einzelnen Tochtersendern zu erhalten, ob diese auch die Impulse empfangen und weitergeleitet haben. Alle Tochtersender werden mit der gleichen Impulsfrequenz gesteuert. Die zu ihnen abgehenden Signale unterscheiden sich also bei dem Zentralsender nicht. Wenn eine Rückmeldung daher unter Verwendung der Impulsfrequenz vorgenommen würde, könnte beim Zentralsender nicht unterschieden werden, ob diese Rückmeldung von allen oder nur einigen Tochtersendern und dann von welchen Tochtersendern gegeben worden ist. Eine Unsicherheit hinsichtlich der Verwirklichung des Signalprogramms ist die Folge. Diese Nachteile beseitigt die Erfindung.Audio frequency remote control system with a central transmitter and daughter transmitters with feedback devices to the central transmitter often different, possibly separate network sections of one Transmitter controlled centrally via a subsidiary transmitter. Feedback is welcome to receive from the individual daughter transmitters whether they also receive the impulses and have forwarded. All daughter transmitters are using the same pulse frequency controlled. The outgoing signals to them therefore differ for the central transmitter not. When feedback is therefore made using the pulse frequency at the central station it would not be possible to distinguish whether this feedback given by all or only some of the subsidiary transmitters and then by which subsidiary transmitters has been. An uncertainty regarding the realization of the signal program is the consequence. The invention overcomes these disadvantages.

Es sind zwar Fernsteueranlagen bekannt, bei denen die einzelnen Tochtersender mit der zentralen Sendestelle über je eine Steuerleitung verbunden sind und bei der die Kontrolle des Schaltzustandes über diese Steuerleitungen erfolgt. Jedoch ist die Verlegung von Steuerleitern, die bei einem ohnehin vorhandenen Netz. zusätzlich erfolgen müßte, mit erheblichen Kosten verbunden und deshalb unvorteilhaft.Although remote control systems are known in which the individual daughter transmitters are connected to the central transmission point via a control line each and at which the control of the switching status takes place via these control lines. However is the laying of control ladders in an already existing network. Additionally would have to take place, associated with considerable costs and therefore disadvantageous.

Mit der Erfindung wird eine Fernsteueranlage mit einer zentralen Sendestelle, die verschiedene gegebenenfalls voneinander getrennte Netzabschnitte über Tochtersender steuert, vorgeschlagen, bei der die erwähnten 1Tachteile, die in bezug auf die Rückmeldeeinrichtung bestehen, vermieden werden.With the invention, a remote control system with a central transmission point, the various network sections, possibly separated from one another, via subsidiary transmitters controls, proposed in which the mentioned 1 disadvantages, with respect to the feedback device exist, be avoided.

Erfindungsgemäß wird eine für jeden Tochtersender andere Modulierung der Tonfrequenz mit einer von den Netzoberwellen abweichenden Frequenz beispielsweise mittels eines zwischen Phase-Erde oder Phase-Phase des Netzes gelegten steuerbaren Entladungsgefäßes, dessen Widerstand der Modulationsfrequenz entsprechend geändert wird, vorgenommen. Statt eines veränderlichen Widerstandes kann zur Modulation auch ein besonderer Sender, der mit dem Tochtersender zugleich angetrieben wird, eingesetzt werden.According to the invention, a different modulation is used for each subsidiary transmitter the audio frequency with a frequency deviating from the mains harmonics, for example by means of a controllable one placed between phase-earth or phase-phase of the network Discharge vessel, the resistance of which changed according to the modulation frequency is made. Instead of a variable resistance, modulation can also be used a special transmitter that is driven at the same time as the daughter transmitter is used will.

Am Zentralsender wird ein Empfänger aufgestellt, der zur Auswahl der verschiedenen Rückmeldungssignale mit einer der Zahl der Tochtersender entsprechenden Anzahl von Saugkreisen, die jeweils auf eine Modulationsfrequenz eines Tochtersenders abgestimmt sind, ausgerüstet ist. Durch diesen Empfänger können die Rückmeldungsimpulse voneinander getrennt werden, so daß eine Beobachtung der Funktion der einzelnen Tochtersender von dem Zentralsender aus möglich wird,A receiver is set up at the central transmitter to select the different feedback signals with one corresponding to the number of daughter transmitters Number of suction circuits, each based on a modulation frequency of a daughter transmitter are matched, is equipped. The feedback pulses can be sent through this receiver separated from each other so that an observation of the function of each Daughter transmitter becomes possible from the central transmitter,
