Description

Die Erfindung betrifft eine Anordnung zum Steuern eines Ventils nach dem Oberbegriff des Anspruchs 1.The invention relates to an arrangement for controlling a valve according to the preamble of claim 1.

Eine derartige Anordnung ist aus der DE-OS 06 507 bekannt. Durch diese Anordnung wird das zugehörige Ventil verhältnismäßig träge und ungenau gesteuert. Etwaige, z. B. durch Verschmutzung oder dergleichen hervorgerufene Verklemmungen des Ventilkorpers können nicht festgestellt und berücksichtigt werden.Such an arrangement is known from DE-OS 06 507. This arrangement makes that associated valve relatively sluggish and imprecisely controlled. Any, z. B. by pollution or the like caused jamming of the valve body cannot be determined and taken into account will.

Der Erfindung liegt daher die Aufgabe zugrunde, die bekannte Anordnung so zu verbessern, daß eine schnei-Ie und zuverlässige Steuerung des zugehörigen Ventils möglich ist.The invention is therefore based on the object of improving the known arrangement so that a snow-Ie and reliable control of the associated valve is possible.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.

Die erfindungsgemäße Anordnung läßt sich verhältnismäßig einfach herstellen und gewährleistet ein sehr genaues Abtasten und Steuern der Ventilstellung. Sie läßt sich in Form eines Ventil-Oberteils mittels entsprechender Adapfer an alle gängigen Ventil-Unterteile anpassen, so daß auch ein nachträglicher Einbau möglich en ist.The arrangement according to the invention can be relatively easy to manufacture and ensures very precise scanning and control of the valve position. she can be adapted to all common valve lower parts in the form of a valve upper part by means of appropriate adapters, so that subsequent installation is also possible.

Besonders vorteilhaft beim Einsatz der erfindungsgemäßen Anordnung ist die individuelle Steuermöglichkeit aller Heizkörper einer Wohnungseinheit in einem Mehrfamilienhaus, das durch eine zentrale Warmwasserheizungsanlage bedient wird. Dadurch kann der Wärmemengenverbrauch äußerst wirtschaftlich gestaltet werden.The possibility of individual control is particularly advantageous when using the arrangement according to the invention of all radiators in an apartment unit in an apartment building, which are provided by a central hot water heating system is served. As a result, the amount of heat used can be made extremely economical will.

Anhand eines Blockschaltbildes wird eine vorteilhafte Ausführungsform der Erfindung näher erläutertAn advantageous embodiment of the invention is explained in more detail with the aid of a block diagram

Das in der Figur gezeigte Ventil-Oberteil sitzt auf einem Ventil-Unterteil 70, das von einem Heiz- oder Kühlmedium 72 durchströmt wird. Die im Medium 72 mitgeführten, zu Steuerzwecken eingegebenen Ultraschallschwingungen 62 werden von Ultraschallempfängern 30, 60 aufgenommen. Die empfangenen Schwingungen 62 werden in elektrische Ströme umgewandelt und einem elektronischen Empfänger 80 sowie dem nicht dargestellten Ladegerät einer Batterie 32 zugeführt. Der Empfänger 80 erkennt aus den eingeführten Steuerimpulsen Adresse, Programmnummer, unter Umstc-nden Raumnummer, Heizkörper-Nummer und Befeh/sstruktur, scheidet auf der Leitung zugefühne falsche Impulse aus und bereitet die Übermittlung zu einer Steuerlogik 90 vor. Die Steueriogik 90 erkennt aus dem vom Empfänger 80 erhaltenen Signal die Befehlsuruktur. Je nach Befehlsart werden Vergleiche des jeweils gemessenen Ist-Zustandes mit vorbestimmten Soll-Werten durchgeführt und entsprechende Befehle an eine Motorsteuerung 36 ausgegeben. Die Steuerlogik 90 überprüft laufend das Temperaturverhalten von Temperaturfühlern 20 und 22 und gibt jeweils die erkennbaren Temperaturdifferenzen als Steuerimpulse an die Motorsteuerung 36 weiter.The valve upper part shown in the figure sits on a valve lower part 70, which is of a heating or Cooling medium 72 is flowed through. The ultrasonic vibrations carried along in the medium 72 and input for control purposes 62 are received by ultrasonic receivers 30, 60. The vibrations received 62 are converted into electrical currents and an electronic receiver 80 as well as the Charger, not shown, is supplied to a battery 32. The receiver 80 recognizes from the introduced Control impulses address, program number, possibly room number, radiator number and command structure, eliminates false impulses inflicted on the line and prepares the transmission to one Control logic 90 before. The control logic 90 recognizes the command structure from the signal received from the receiver 80. Depending on the type of command, comparisons of the respectively measured actual state with predetermined target values are made carried out and corresponding commands to a Motor control 36 output. The control logic 90 continuously checks the temperature behavior of temperature sensors 20 and 22 and sends the recognizable temperature differences as control pulses to the Motor control 36 further.

Der Öffnungsgrad des. Ventilunterteils wird bei dieser Ausführungsform durch die Stellung und Lage eines Ferritkerns 50 wiedergegeben, welcher die Auf- und Zu-Bewegungen des Ventilkorpers mitvollzieht Die Ventilkörperstellung wird mittels der Änderung der Induktivität einer umgebenden Spule 52 der Steueriogik 90 mitgeteilt Ferner wird mittels eines Temperaturfühlers 24 die Medientemperatur am Ventil abgetastet und ebenfalls der Steuerlogik 90 mitgeteilt Diese beiden Parameter ergeben in Verbindung mit einer Zeittakteingabe eine genaue Ermittlung der Wärmemengenabgabe. Ebenso kann durch geeignete Signale, die von der Steuerlogik 90 zur Motorsteuerung 36 g.j£eber. werden, die Öffnung des Ventils beliebig eingestellt werden.In this embodiment, the degree of opening of the lower valve part is represented by the position and location of a ferrite core 50, which also executes the opening and closing movements of the valve body Temperature sensor 24 scanned the media temperature at the valve and also communicated to the control logic 90. These two parameters, in conjunction with a clock input, result in an exact determination of the amount of heat output. Likewise, by means of suitable signals which are sent from the control logic 90 to the engine control 36, gj £ eber. the opening of the valve can be set as desired.

Durch einen Lichtwandler 38 kann während des Tages Licht in elektrische Energie umgewandelt und zum Laden der Batterie 32 verwendet werden.By means of a light converter 38, light can be converted into electrical energy during the day and used for Charging the battery 32 can be used.

Der Ventil-Oberteil kann zusätzlich mit einem Anschluß 34 für Fremdstromeinspeisung versehen sein.The upper part of the valve can also be provided with a connection 34 for external power supply.

Die Wärmemengenabgabe-Daten jedes einzelnen Ventil-Oberteiles können an eine zentrale Wärmemengenabgabe-Registriereinrichtung 100 übermittelt werden. Befehle können auch extern über einen Sender 110 an den Empfänger 80 übermittelt werden.The heat output data of each individual valve upper part can be sent to a central heat output recording device 100 are transmitted. Commands can also be sent externally via a transmitter 110 be transmitted to the receiver 80.
