Description

Die Erfindung betrifft ein Sonnenschutzsystem mit einem in einer geschlossenen Fassade (CCF Closed-Cavity-Fassade) verstellbaren Sonnenschutzbehang nach dem Oberbegriff des Anspruchs 1.The invention relates to a sunshade system having a sunshade curtain which can be adjusted in a closed facade (CCF closed-cavity façade) according to the preamble of claim 1.

Es ist ein Sonnenschutzsystem bekannt, das einen Antriebsmotor mit einem ersten Winkelgetriebe aufweist, die beide außerhalb der geschlossenen Fassade angeordnet sind und wobei das erste Winkelgetriebe über ein dichtendes Durchführungselement durch die Profile der Fassade in den Innenraum der Fassade eingeführt und darin mit einem zweiten Winkelgetriebe verbunden ist und wobei das zweite Winkelgetriebe eine Antriebswendewelle für den Sonnenschutzbehang antreibt.It is known a sunshade system having a drive motor with a first angle gear, both of which are arranged outside the closed facade and wherein the first angular gear is introduced via a sealing feedthrough element through the profiles of the facade in the interior of the facade and connected thereto with a second angular gear and wherein the second angle gear drives a drive shaft for the Sonnenschutzbehang.

Bei diesem Sonnenschutzsystem sind der Antriebsmotor und das erste Winkelgetriebe außerhalb der Fassade angeordnet und problemlos für Wartungs- und Servicezwecke zugänglich. Da in der geschlossenen Fassade zudem klimatische Bedingungen mit Temperaturen bis 100° C und aufgrund einer speziellen Belüftung mit gefilterter, getrockneter Druckluft eine geringe Luftfeuchtigkeit herrschen, kommt es beim Betrieb zu Änderungen der mechanischen Antriebselemente und zudem zu der Länge des Sonnenschutzbehangs, insbesondere dann, wenn die Fassadenelemente topographisch an der Süd- und Nordseite eines Gebäudes angeordnet sind. Diese Längenunterschiede lassen sich bisher nur durch wiederholte Serviceleistungen ausgleichen und beeinträchtigen die Funktion der Klimatisierung der Gebäude erheblich.In this sun shading system, the drive motor and the first bevel gear are located outside the facade and easily accessible for maintenance and service purposes. Since in the closed facade also climatic conditions with temperatures up to 100 ° C and due to a special ventilation with filtered, dried compressed air, a low humidity prevail, it comes to changes in the operation of the mechanical drive elements and also to the length of Sonnenschutzbehangs, especially if the facade elements are arranged topographically on the south and north side of a building. So far, these differences in length can only be compensated for by repeated services and considerably impair the function of the air conditioning of the buildings.

Die Dokumente CH 686 973 A5 , DE 202 19932 A1 und EP 0982 466 A1 betreffen bekannte Sonnenschutzsysteme mit Steuerungsmechanismen.The documents CH 686 973 A5 . DE 202 19932 A1 and EP 0982 466 A1 relate to known sun protection systems with control mechanisms.

Es ist Aufgabe der Erfindung, das Sonnenschutzsystem der eingangs erwähnten Art so weiterzuentwickeln, dass die Länge der Sonnenschutzbehänge ausgeglichen werden kann, ohne derartige zusätzliche Service-Dienstleistungen in Anspruch zu nehmen und damit die Langlebigkeit und den Bedienkomfort des Sonnenschutzes zu erhöhen und zu automatisieren.It is an object of the invention to develop the sunscreen system of the type mentioned so that the length of the sunscreen can be compensated without taking such additional services to complete and thus increase the longevity and ease of use of the sunscreen and automate.

Die gestellte Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The stated object is achieved with the features of claim 1.

Dies ist dadurch erreicht, dass das zweite Winkelgetriebe ein Drehgebermesssystem mit Referenz-Modul über die Antriebswendewelle des Sonnenschutzbehangs antreibt, wobei das Drehgebermesssystem mit Referenz-Modul eine automatische Nachregelung und Einstellung der sich ändernden Länge des Sonnenschutzbehangs ermöglicht.This is achieved in that the second angle gear drives a rotary encoder measuring system with reference module on the drive shaft of the Sonnenschutzbehangs, the rotary encoder measuring system with reference module allows automatic readjustment and adjustment of the changing length of Sonnenschutzbehangs.

Der Drehgeber wird genau auf der Antriebswendewelle des Sonnenschutzbehangs angeordnet. Dadurch kann neben einer direkten Messung der Sonnenschutzbehang-Stellung und -Länge zusätzlich der Antrieb geschaltet bzw. die obere Endlage des Sonnenschutzbehangs als Referenzpunkt ermittelt werden. Mit Hilfe des Drehgebersystems empfängt die Gebäudesteuerung also die tatsächliche Stellung des Sonnenschutzbehangs und übernimmt selbsttätig die regelmäßige Nachjustierung. Optimal lassen sich mit dem Drehgebersystem zudem die Temperatur und die Luftfeuchte in der geschlossenen Fassade messen. Aus diesem Grund kann dann eine aktive Taupunktregelung über die Gebäudesteuerung realisiert werden, die das Belüftungssystem beeinflusst und dadurch das Klima in der Fassade besser kontrollierbar und regelbar macht.The encoder is placed exactly on the drive shaft of the Sonnenschutzbehangs. As a result, in addition to a direct measurement of Sonnenschutzbehang position and length additionally the drive switched or the upper end position of Sonnenschutzbehangs be determined as a reference point. With the aid of the rotary encoder system, the building control system thus receives the actual position of the sunblind and automatically takes over the regular readjustment. In addition, the temperature and humidity in the closed façade can be optimally measured with the encoder system. For this reason, an active dew point control can be implemented via the building control, which influences the ventilation system and thus makes the climate in the facade more controllable and controllable.

Vorteilhafte Ausgestaltungen des Sonnenschutzsystems sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the sun protection system can be found in the dependent claims.

Das Drehgebersystem erfasst direkt die Position des Sonnenschutzbehanges innerhalb der geschlossenen Fassade und gibt diese ohne Fehlereinflüsse an die Gebäudesteuerung weiter.The encoder system directly records the position of the sun protection curtain within the closed façade and forwards it to the building control system without any error.

Das Referenz-Modul erfasst die Referenzposition des Sonnenschutzbehangs meldet diese an die Gebäudesteuerung und diese kompensiert so die vergrößerte Länge des Sonnenschutzbehangs, welcher dann durch reduzieren der Anzahl der Umdrehungen der Antriebswendewelle die Sonnenschutzbehanglänge anpasst.The reference module detects the reference position of the sunblind, reports it to the building control and compensates for the increased length of the sunblind, which then adjusts the sunshade length by reducing the number of revolutions of the drive shaft.

Das Referenz-Modul erfasst in gleicher Weise auch die Referenzposition des Sonnenschutzbehangs, meldet diese an die Gebäudesteuerung und diese kompensiert so bei verkürzter Länge des Sonnenschutzbehangs, welcher dann durch vergrößern der Anzahl der Umdrehungen der Antriebswendewelle die Sonnenschutzbehanglänge anpasst.The reference module detects in the same way also the reference position of the Sonnenschutzbehangs, reports this to the building control and this compensates for shortened length of Sonnenschutzbehangs, which then adjusts the Sonnenschutzbehanglänge by increasing the number of revolutions of the drive shaft.

Die Referenz-Module mehrerer Sonnenschutzbehänge verschiedener geschlossener Fassaden sind mit einem zentralen Steuergerät, der Gebäudesteuerung, verbunden, das mit den Referenz-Modulen der verschiedenen Sonnenschutzbehänge verbunden ist und den erforderlichen Längenausgleich ausführt und dabei die Anzahl der erforderlichen Neupositionierung der Antriebswendewelle vornimmt.The reference modules of several sunblinds of different closed facades are connected to a central control unit, the building control, which is connected to the reference modules of the various sunblinds and performs the required length compensation while doing the number of repositioning required the drive shaft.

Im Drehgebersystem sind zusätzlich die Temperatur und die Luftfeuchte messbar, um eine aktive Taupunktregelung zu realisieren, die das Belüftungssystem der Fassade beeinflusst und das Klima in der Fassade besser kontrollierbar macht.In addition, the temperature and humidity can be measured in the rotary encoder system in order to realize an active dew point control, which influences the ventilation system of the façade and makes it easier to control the climate in the façade.

Die Erfindung wird anhand der Zeichnungen an Ausführungsbeispielen der Erfindung näher erläutert. Es zeigen:

The invention will be explained in more detail with reference to the drawings of embodiments of the invention. Show it:
Fig.1
schematically the structure of the sun protection system and
Fig. 2
a sun protection system with a central control unit.

Wie Fig. 1 erkennen lässt, handelt es sich bei dem Sonnenschutzsystem um eine geschlossene Fassade 10, die aus Aluminiumprofilen zusammengesetzt ist. Dabei bildet die Fassade 10 einen oberen Kasten, in dem eine Antriebswendewelle 12 abgeordnet ist, die den Sonnenschutzbehang 11 je nach Drehrichtung der Antriebswendewelle 12 nach unten oder nach oben verstellt. An der Antriebswendewelle 12 ist ein Drehgebersystem adaptiert, welches ein Referenz-Modul beinhaltet. Der Antrieb umfasst einen Antriebsmotor 13 und ein erstes Winkelgetriebe 14, die beide außerhalb der Fassade 10 angeordnet sind. Das erste Winkelgetriebe 14 ist über ein Durchführungselement 15 in die geschlossene Fassade 10 eingeführt und dort mit dem zweiten Winkelgetriebe 16 verbunden, das sich in der Oberschiene des Sonnenschutzes 18 befindet und diese in der Fassade 10 gelagert ist. Das zweite Winkelgetriebe 16 treibt die Antriebswendewelle 12 an, auf der ein Drehgeber 17 adaptiert ist. Der Drehwertgeber 17 ist dabei so ausgebildet, dass er die Position des Sonnenschutzbehangs 11 erfasst, d. h. er erfasst, ob aufgrund der Bedingungen in der Fassade 10 der Sonnenschutzbehang 11 sich in der Länge vergrößert oder verkürzt hat. Demzufolge kann diese Änderung vollautomatisch ausgeglichen werden. Der Drehantrieb der Antriebswendewelle 12 wird dabei um eine bestimmte Anzahl von Umdrehungen reduziert oder erhöht, um diese Längenänderungen auszugleichen. Dies kann in jeder geschlossenen Fassade 10 individuell ausgeführt werden. Dabei kann das Sonnenschutzsystem zusätzlich mit einem Temperatur-Messsensor und einem Luftfeuchtigkeits-Messsensor versehen sein, um eine aktive Taupunktregelung zu realisieren, die das Belüftungssystem der Fassade 10 beeinflusst und das Klima in der Fassade 10 besser kontrollierbar und dynamisch regelbar macht.As Fig. 1 As can be seen, the sunshade system is a closed facade 10, which is composed of aluminum profiles. In this case, the facade 10 forms an upper box, in which a drive shaft 12 is seconded, which adjusts the Sonnenschutzbehang 11 depending on the direction of rotation of the drive shaft 12 down or up. At the drive shaft 12, a rotary encoder system is adapted, which includes a reference module. The drive comprises a drive motor 13 and a first angle gear 14, both of which are arranged outside the facade 10. The first angle gear 14 is inserted via a feedthrough element 15 in the closed facade 10 and connected there to the second angle gear 16, which is located in the upper rail of the sunshade 18 and this is mounted in the facade 10. The second angle gear 16 drives the drive shaft 12, on which a rotary encoder 17 is adapted. The rotary encoder 17 is designed so that it detects the position of the Sonnenschutzbehangs 11, ie it detects whether due to the conditions in the facade 10 of the Sonnenschutzbehang 11 increases in length or shortened Has. As a result, this change can be compensated fully automatically. The rotary drive of the drive shaft 12 is thereby reduced or increased by a certain number of revolutions to compensate for these changes in length. This can be done individually in each closed facade 10. The sun protection system may additionally be provided with a temperature measuring sensor and an air humidity measuring sensor in order to realize an active dew point control, which influences the ventilation system of the facade 10 and makes the climate in the facade 10 more controllable and dynamically controllable.

In Fig. 2 ist ein Ausführungsbeispiel gezeigt, bei dem die Drehgebersysteme mit ihren Referenz-Modulen 17 in mehreren Fassaden 10 verschiedener Sonnenschutzsysteme, z. B. der Südseite und der Nordseite eines Gebäudes, mit einem zentralen Steuergerät 20 verbunden sind. In vorgegebenen Zeitabständen wird das zentrale Steuergerät 20 nacheinander mit den Referenz-Modulen 17 der verschiedenen Fassaden 10 gekoppelt und die Längenkorrektur individuell durchgeführt. Dabei kann je nach der Gegebenheit der Positionen der Sonnenschutzbehänge 11 in den verschiedenen Fassaden 10 eine Erhöhung oder eine Reduzierung der Drehung der Antriebswendewelle 12 um bestimmte Umdrehungen erforderlich sein. Auch in diesem Ausführungsbeispiel kann durch zusätzliche Temperatur- und Luftfeuchtigkeitsmessgeräte in den Fassaden 10 eine aktive Taupunktregelung vorgenommen werden. Das zentrale Steuergerät 20 kann dabei die erforderliche Anzahl von Umdrehungen vorgeben und misst die aktuelle Position des Sonnenschutzbehangs über das Drehgebersystem. Dabei können Schaltimpulse die Erhöhung oder die Reduzierung der Anzahl der Umdrehungen der Antriebswendewelle 12 vorgeben. Der Informationsaustausch zwischen dem zentralen Steuergerät 20 und den verschiedenen Drehgebersystemen 17 in den Fassaden 10 kann auch anders erfolgen, ohne den erfinderischen Gedanken des neuen Sonnenschutzsystems zu verlassen.In Fig. 2 an embodiment is shown in which the encoder systems with their reference modules 17 in several facades 10 different sun protection systems, for. B. the south side and the north side of a building, are connected to a central control unit 20. At predetermined time intervals, the central control unit 20 is successively coupled to the reference modules 17 of the various facades 10 and the length correction is carried out individually. Depending on the circumstances of the positions of the sun protection hangings 11 in the various facades 10, an increase or a reduction in the rotation of the drive torque shaft 12 by certain revolutions may be required. Also in this embodiment can be made by additional temperature and humidity meters in the facades 10, an active dew point control. The central control unit 20 can specify the required number of revolutions and measures the current position of the Sonnenschutzbehangs on the encoder system. In this case, switching pulses, the increase or reduce the number of revolutions of the drive shaft 12 specify. The exchange of information between the central controller 20 and the various encoder systems 17 in the facades 10 can also be done differently without departing from the inventive idea of the new sunscreen system.
