Description

Vorrichtung für netzbetriebene Schaltuhren mit elektrischer Ganqreserve.Device for mains-operated time switches with electrical gantry reserve.
Die Erfindung betrifft eine Vorrichtung für netzbetriebene Schaltuhren mit elektrischer, batteriebetriebener Gangreserve, zur steuerbaren elektrischen Zuschaltung der Gangreserve-Batterie zur netzbetriebenen Energieversorgung des Antriebs der Schaltuhr.The invention relates to a device for mains-operated time switches with electrical, battery-operated power reserve, for controllable electrical connection of the power reserve battery for mains-operated energy supply to the drive of the time switch.
Bei derartigen Schaltuhren, insbesondere mit einem quarzgesteuertem Antrieb ist es erforderlich, daß die Gangreserve zum Zeitpunkt ihrer Zuschaltung zur Energieversorgung des Antriebs der Schaltuhr die volle, ihr zugemessene energetische Kapazität aufweist.In such time switches, in particular with a quartz-controlled drive, it is necessary for the power reserve to have the full energy capacity assigned to it for the energy supply of the drive for the time switch when it is switched on.
Bei bekanntgewordenen derartigen Schaltuhren liegt die Gangreserve-Batterie elektrisch unmittelbar parallel zur netzbetriebenen Energieversorgung der Schaltuhr und liefert dem dortigen Antriebssystem elektrische Energie wann immer die Energieversorgung aus dem Netz fehlt. D.h. es wird dort fortlaufend insbesondere auch während der Lagerzeit oder der Transportzeit zwischen Hersteller und Kunden unnötigerweise Energie aus der Gangreserve-Batterie entnommen. Dies ist auch der Fall, wenn derartige Uhren nach ihrer Installation beim Kunden einen längeren Probelauf oder einer Anlagenprüfung ausgesetzt werden.In the case of such time switches that have become known, the power reserve battery is electrically directly parallel to the mains-operated energy supply of the time switch and supplies the drive system there with electrical energy whenever the energy supply from the mains is missing. That There is continuously unnecessary energy drawn from the power reserve battery, especially during the storage period or the transport time between the manufacturer and the customer. This is also the case if such watches are subjected to a long trial run or a system test after they have been installed by the customer.
In jedem Falle wird dadurch bei den bekannten derartigen Schaltuhren die Kapazität der Gangreserve-Batterie erheblich beeinträchtigt, indem die dort verwendeten Akkumulatoren vielfach tief entladen werden, sodaß zum Zeitpunkt der eigentlichen Inbetriebnahme einer solchen Schaltuhr die volle, der Uhr vom Hersteller zugemessene, Gangreserve nicht gleich oder nicht mehr - je nach Batteriesystem - zur Verfügung steht.In any case, the capacity of the power reserve battery is significantly impaired in the known time switches of this type, in that the accumulators used there are often deeply discharged, so that the full power reserve assigned to the clock by the manufacturer is not the same at the time when such a time switch is actually put into operation or no longer - depending on the battery system - is available.
Der Erfindung liegt die Aufgabe zugrunde, Schaltuhren der vorstehend genannten Art dahingehend zu verbessern und sie mit einer einfachen Vorrichtung zu versehen, die gewährleistet und es ermöglicht, daß zum Zeitpunkt der eigentlichen Inbetriebnahme einer Schaltuhr oder zeitlich unwesentlich danach eine kapazitätsmäßig elektrisch! volle Gangreserve Batterie der netzbetriebenen Energieversorgung des Antriebs der Schaltuhr zugeschaltet wetden kann. Dabei soll sichergestellt sein, daß der Zeitpunkt der Zuschaltung der Gangreserve-Batterie, bezogen auf den Zeitpunkt an dem eine Schaltuhr erstmalig in Betrieb gesetzt wurde, vorwählbar ist.The invention has for its object to improve time switches of the type mentioned above and to provide them with a simple device that ensures and makes it possible that at the time of the actual commissioning of a time switch or irrelevant in time thereafter a capacity electrical! full power reserve Battery of the mains operated power supply of the drive of the time switch can be switched on. It should be ensured that the time at which the power reserve battery is switched on can be preselected, based on the time at which a time switch was started for the first time.
Die Erfindung wird aufgabengemäß mit den Merkmalen im kennzeichnenden Teil des Patentanspruchs 1 gelöst.The invention is achieved according to the features in the characterizing part of claim 1.
Vorteilhaft bei dieser Vorrichtung für Schaltuhren ist nicht nur, daß zum Zeitpunkt der eigentlichen Aufnahme der zeitlichen Steuerungsfunktion einer Schaltuhr eine kapazitätsmäßig elektrisch volle Gangreserve-Batterie zeitlich vorwählbar selbsttätig zugeschaltet wird, sondern daß es dadurch auch ermöglicht wird, wirtschaftliche Primärelemente als Gangreserve-Batterien im Vergleich zu nachladbaren Akkumulatoren zu verwenden, ohne dabei gefahrlaufen zu müssen, daß diese, wie auch die bisher verwendeten nachladbaren Akkumulatoren, zum Zeitpunkt der eigentlichen Aufnahme des Betriebs der Schaltuhr entladen oder unbrauchbar sind. Vorteilhaft ist ferner, daß auch längere funktionslose Lagerzeiten - insbesondere ohne Netzbetrieb oder längere Probelaufzeiten - keinen Einfluß auf die Kapazität einer elektrisch vollen Gangreserve-Batterie hat.The advantage of this device for time switches is not only that at the time when the time control function of a time switch is actually started, an electrically full power reserve battery is switched on automatically in a preselectable manner, but that it also makes it possible to compare economical primary elements as power reserve batteries to use rechargeable batteries without having to run the risk that, like the rechargeable batteries previously used, they are discharged or unusable at the time the timer is actually started. It is also advantageous that even longer non-functional storage times - especially without mains operation or longer test runs - have no influence on the capacity of an electrically full power reserve battery.
Ausführungsbeispiele der Vorrichtung nach der Erfindung sind prinzipiell im wesentlichen in der Zeichnung dargestellt und werden im folgenden erläutert. Es zeigenEmbodiments of the device according to the invention are basically shown in the drawing and are explained below. Show it
Fig. 1 ein Blockschaltbild einer netzbetriebenen elektronischenFig. 1 is a block diagram of a network-operated electronic
Schaltuhr mit im Stromkreis der Gangreserve-Batterie vorgesehener elektronischer Zeitverzögerungsvorrichtung undTime switch with electronic time delay device provided in the circuit of the power reserve battery and
Fig. 2 ein Blockschaltbild einer Schaltuhr nach Fig. 1 mit einem Mikroprozessor anstelle einer elektronischen Zählstufe und mit einer elektronischen Netzerkennung.Fig. 2 is a block diagram of a timer according to Fig. 1 with a microprocessor instead of an electronic counter and with electronic network detection.
Die, in der Fig. 1 nur als Blockschaltbild dargestellte Schaltuhr besteht im einzelnen aus dem netzbetriebenen Energieversorgungsteil 12, dem dort parallel zum dortigen Gleichspannungsausgang 13 die Gangreserve-Batterie 2 zugeordnet ist, in deren Stromkreis 1 ein Halbleiterschalter 18 inform eines Transistors geschaltet ist.The time switch shown in FIG. 1 only as a block diagram consists in particular of the mains-operated energy supply part 12, to which the power reserve battery 2 is assigned parallel to the DC voltage output 13 there, in the circuit 1 of which a semiconductor switch 18 is connected to a transistor.
Dieser Halbleiterschalter 18 wird von einem diskreten Zeitmeßglied angesteuert, dessen Schaltzeit insbesondere vorwählbar ist. Damit ist es möglich, die Gangreserve-Batterie 2 erst nach einem gewissen Zeitraum der Laufzeit einer solchen Schaltuhr am Netz, von ca. 100 Stunden, zuzuschalten, um dadurch sicherzustellen, daß auch nach einer längeren Lager-oder Transportzeit, oder nach einer längeren Probelaufzeit am Netz, die vorgesehene Gangreserve-Batterie 2 mit der eigentlichen Inbetriebnahme der Schaltuhr ihre volle Kapazität besitzt und nicht die Gangreserve-Batterie 2 bei der Inbetriebnahme der Schaltuhr in ihrer Kapazität beeinträchtigt oder völlig entladen war, wie dies bei den bekannten Schaltuhren mit Gangreserve vielfach der Fall war.This semiconductor switch 18 is controlled by a discrete time measuring element, the switching time of which can in particular be preselected. It is thus possible to switch on the power reserve battery 2 only after a certain period of time of such a timer on the network, of approximately 100 hours, in order to ensure that even after a longer storage or transport time or after a longer trial run on the network, the power reserve battery 2 provided with the actual commissioning of the time switch has its full capacity and the power reserve battery 2 was not impaired in its capacity or completely discharged when the time switch was started up, as was often the case with the known time switches with power reserve Case was.
Das Zeitmeßglied, das den Halbleiterschalter 18 ansteuert kann ein elektronischer Zähler sein, der zweckmäßigerweise unmittelbar in einer Elektronik 9 der Schaltuhr integriert ist. Der Zähler wird bei Netzbetrieb durch einen Takt von der Elektronik 9 hochgezählt. Wird dabei das Netz ausgeschaltet, dann wird der erreichte Zählerstand gelöscht, da die Gangreserve-Batterie 2 noch nicht zugeschaltet ist. Wird aber die vorgegebene Zähleinheit erreicht, dann schaltet der Zähler die Gangreserve-Batterie 2 zu und bleibt über die Gangreserve im geschalteten Zustand. Es kann dort jedoch auch eine entsprechende Selbsthalteschaltung über den Transistor vorgesehen werden.The time measuring element which controls the semiconductor switch 18 can be an electronic counter, which is expediently integrated directly into electronics 9 of the time switch. The counter is incremented by the electronics 9 during a network operation. If the mains is switched off, the meter reading reached is deleted, since the power reserve battery 2 has not yet been switched on. If, however, the predetermined counting unit is reached, the counter switches on the power reserve battery 2 and remains in the switched state via the power reserve. However, a corresponding self-holding circuit can also be provided there via the transistor.
Anstelle der zuvor beschriebenen Zählstufe ist es auch vorgesehen, einen Mikroprozessor einzusetzen, wie dies die Fig. 2 schematisch zeigt. Der Mikroprozessor 19 kann dort auch unmittelbar Bestandteil der erforderlichen Elektronik bei einer vollelektronischen Schaltuhr sein. Der Mikroprozessor 19 ist zweckmäßigerweise mit einer speziellen Zählschleife zur Steuerung der Einschaltzeit für die Gangreserve-Batterie 2 versehen. Außerdem kann dort eine Netzerkennung am Mikro prozessor 19 anliegen, zur Steuerung der Zuschaltung der Gangreserve-Batterie 2.Instead of the counter stage described above, it is also provided to use a microprocessor, as shown schematically in FIG. 2. The microprocessor 19 can also be directly part of the electronics required for a fully electronic timer. The microprocessor 19 is expediently provided with a special counting loop for controlling the switch-on time for the power reserve battery 2. There can also be a network detection on the microphone processor 19 are present, for controlling the connection of the power reserve battery 2.
Es liegt im Rahmen der Erfindung, daß die Gangreserve-Batterie 2 auch bereits zu einem früheren Zeitpunkt als dem vorgewählten zugeschaltet werden kann, wenn eine entsprechende Batteriezustandsmeßeinrichtung vorgesehen ist und der eingebauten entsprechenden Elektronik einen entsprechenden Schaltbefehl erteilt. Dies kann dann erforderlich sein, wenn die vorgesehene Verzögerungszeit fast abgelaufen ist und der Zustand der Gangreserve-Batterie 2 relativ gut ist. Dies kann der Fall sein, wenn kurz vor Ablauf der Verzögerungszeit das Netz ausfällt und eine Netzerkennung einen entsprechenden Befehl abgibt. It is within the scope of the invention that the power reserve battery 2 can also be switched on at an earlier point in time than the preselected one, if a corresponding battery condition measuring device is provided and issues a corresponding switching command to the built-in corresponding electronics. This may be necessary when the intended delay time has almost expired and the condition of the power reserve battery 2 is relatively good. This can be the case if the network fails shortly before the delay time expires and network detection issues a corresponding command.
