Description

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, wobei eine im Stromkreis der Batterie liegende Schalteinrichtung mit einem Halbleiterschalter vorgesehen ist, die die Gangreserve-Batterie erst nach dem Anschalten der Schaltuhr an das Netz wirksam schaltet.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, wherein a switching device located in the circuit of the battery is provided with a semiconductor switch, which only the power reserve battery after switching on the time switch to the mains.

Bei derartigen Schaltuhren, insbesondere mit einem quartzgesteuerten 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 allocated to it for the energy supply of the drive for the time switch when it is switched on.

Aus der GB-A-2 136 166 ist eine netzbetriebene elektronische Uhr, vorzugsweise eine Schaltuhr mit einem elektrischen Energiespeicher als Gangreserve, bekannt, bei der mit der tastaturartigen Eingabevorrichtung eine Prüfschaltung zusammengeschaltet ist, wobei durch die Prüfschaltung bei Vorleigen einer Nichtbetätigung der Eingabevorrichtung ein Sperrsignal erzeugbar ist, welche die Gangreserve derart ansteuert, daß diese unwirksam geschaltet ist.From GB-A-2 136 166 a mains-operated electronic clock, preferably a time switch with an electrical energy store as a power reserve, is known, in which a test circuit is connected to the keyboard-like input device, whereby a blocking signal is provided by the test circuit when the input device is not actuated Can be generated, which controls the power reserve so that it is ineffective.

Diese Vorrichtung, die wirksam an die Eingabevorrichtung gekoppelt ist, ist mit dem Nachetil versehen, daß sie unbewußt oder fälschlicherweise ausgelöst werden kann, d. h. wenn die Eingabevorrichtung betätigt wird und die Uhr noch nicht an das Netz angeschlossen ist.This device, which is operatively coupled to the input device, is provided with the after-style that it can be triggered unconsciously or erroneously, e.g. H. when the input device is operated and the watch is not yet connected to the mains.

Aus der DE-A-2749420 ist eine Einschaltvorrichtung für eine Hilfsstromquelle eines Gerätes bekannt, das ordnungsgemäß aus einer Hauptstromquelle betrieben wird, wobei eine elektronische Triggerschaltung vorgesehen ist, die mit einem, von Hand zu betätigenden, Schalter, nur bei Anstehen einer Spannung aus der Hauptstromquelle zum Einschalten gebracht wird, wobei damit ein, aus der Hauptstromquelle gespeistes, Relais erregt wird und dieses Relais die Speisung und den Eingang des Triggers, sowie die Relaisspule parallel zur Hauptstromquelle und die Hilfsstromquelle an das Gerät schaltet.From DE-A-2749420 a switch-on device for an auxiliary power source of a device is known, which is operated properly from a main power source, an electronic trigger circuit is provided, which with a manually operated switch, only when a voltage from the Main power source is switched on, whereby a relay, which is fed from the main power source, is excited and this relay switches the supply and the input of the trigger, as well as the relay coil in parallel to the main power source and the auxiliary power source to the device.

Diese Vorrichtung ist relativ umständlich nur von hand bedienbar, und bietet durch seinen technisch erheblichen Aufwand keinen funktionstechnischen Vorteil.This device is relatively cumbersome to operate only by hand and offers no functional advantage due to its technically considerable effort.

Aus der US-A-3 543 044 ist ein netzbetriebener Timer bekannt, der bei einem Netzausfall automatisch auf eine Reservebatterie geschaltet wird. Dabei ist eine magnetische Entladeüberwachung der Reservebatterie vorgesehen, die den Stromkreis zur Batterie unterbricht, wenn die Batteriespannung einen Mindestwert erreicht. Diese Vorrichtung kann die eingangs gestellten Erfordernisse jedoch nicht erfüllen.From US-A-3 543 044 a mains operated timer is known which is automatically switched to a backup battery in the event of a mains failure. Magnetic discharge monitoring of the reserve battery is provided, which interrupts the circuit to the battery when the battery voltage reaches a minimum value. However, this device cannot meet the requirements set out at the beginning.

Der Erfindung liegt die Aufgabe zugrunde, Schaltuhren der eingangs genannten Art dahingehend zu verbessern und sie mit einer einfachen Vorrichtung zu versehen, die gewährleistet, daß zum Zeitpunkt der eigentlichen Inbetriebnahme einer Schaltuhr oder zeitlich unwesentlich danach, eine in ihrer Kapazität elektrisch volle Gangreserve-Batterie der netzbetriebenen Energieversorgung des Antriebs der Schaltuhr zugeschaltet werden 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 wird, vorwählbar ist.The invention has for its object to improve time switches of the type mentioned and to provide them with a simple device that ensures that at the time of the actual commissioning of a time switch or irrelevant in time thereafter, an electrically full power reserve battery in the capacity mains-operated energy 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 is started up for the first time.

Diese Aufgabe wird nach der Erfindung mit dem Merkmalen im kennzeichnenden Teil des Patentanspruchs 1 gelöst; in den abhängigen Ansprüchen sind weitere vorteilhafte Einzelheiten beansprucht.This object is achieved according to the invention with the features in the characterizing part of patent claim 1; further advantageous details are claimed in the dependent claims.

Vorteilhaft bei dieser Vorrichtung für Schaltuhren ist nicht nur, daß zum Zeitpunkt der eigentlichen Inbetriebnahme einer Schaltuhr, eine in der elektrischen Kapazität volle Gangreserve-Batterie zeitlich vorwählbar selbsttätig zugeschaltet wird, sondern daß es dadurch auch ermöglicht wird, wirtschaftliche Primärelemente als Gangreserve-Batterien im Vergliech zu nachladbaren Akkumulatoren einzusetzen, ohne daß zu befürchten ist, daß die jeweils verwendete Gangreserve-Batterie zum Zeitpunkt der eingentlichen Inbetriebnahme der Schaltuhr entladen oder gar unbrauchbar ist.The advantage of this device for time switches is not only that when a time switch is actually put into operation, a full power reserve battery is automatically switched on at a preselectable time, but that it also makes it possible to compare economical primary elements as power reserve batteries to be used for rechargeable batteries without fear that the power reserve battery used in each case is discharged or even unusable at the time the timer is actually started up.

Ausführungsbeispiele der Vorrichtung nach der Erfindung sind prinzipiell im wesentlichen in der Zeichnung dargestellt und werden im folgenden erläutert. Es zeigen

  • Fig. 1 ein Blockschaltbild einer netzbetriebenen elektronischen Schaltuhr mit im Stromkreis der Gangreserve-Batterie vorgesehener elektronischer Zeitverzögerungsvorrichtung und
  • Fig. 2 ein Blockschaltbild einer Schaltuhr nach Fig. 1 mit einem Mikroprozessor anstelle einer elektronischen Zählstufe und mit einer elektronischen netzerkennung.
Embodiments of the device according to the invention are basically shown in the drawing and are explained below. Show it
  • Fig. 1 is a block diagram of a mains operated electronic timer with the electronic time delay device provided in the circuit of the power reserve battery and
  • Fig. 2 is a block diagram of a timer according to Fig. 1 with a microprocessor instead of an electronic counter and with an electronic network recognition.

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 detail of the mains-operated energy supply part 12, to which the power reserve battery 2 is assigned in parallel with the DC voltage output 13 there, in the circuit 1 of which a semiconductor switch 18 is connected to a transistor.

Dieser Habiefterschalter 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 bekannten vielfach der Fall war.This Habiefterschalter 18 is controlled by a discrete timing element, the switching time is particularly selectable. This makes it possible to switch on the power reserve battery 2 only after a certain period of time of such a time switch on the network, of about 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 intended power reserve battery 2 has its full capacity with the actual start-up of the time switch and the power reserve battery 2 was not impaired in its capacity or completely discharged when the time switch was started up, as was the case with the known ones Time switches with well-known was often the case.

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. However, if 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 erforcerlichen 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. Au- ßerdem kann dort eine netzerkennung am Mikroprozessor 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 part of the required electronics in 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. In addition, there can be a network detection on the microprocessor 19 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.
