Description

Die Erfindung betrifft ein Verfahren zur Ansteuerung eines Gebäude-Trinkwassernetzwerks mit Sanitärarmaturen mittels eines internetbasierten Cloud-Serversystems gemäß Anspruch 1 sowie ein Hygienespülsystem gemäß Anspruch 16.The invention relates to a method for controlling a building drinking water network with sanitary fittings using an internet-based cloud server system according to claim 1 and a hygiene flushing system according to claim 16.

Die Hygieneanforderungen bei der Trinkwasserversorgung von Gebäuden oder Gebäudekomplexen sind in den letzten Jahren deutlich gestiegen. Der Grund hierfür ist die Erkenntnis, dass über längere Zeit im Gebäude-Trinkwassernetzwerk stehendes Wasser, das auch als Stagnationswasser bezeichnet wird, zur ungewünschten Bildung von Keimen führen kann. In diesem Zusammenhang stellen Legionellen oder ähnliche Keime ein Gesundheitsrisiko dar. Folgerichtig ist dazu übergegangen worden, das betreffende Gebäude-Trinkwassernetzwerk regelmäßig zu spülen, was vorliegend als "Hygienespülen" bezeichnet wird. Dabei werden die Keime je nach Spülstrategie ausgespült, dezimiert und/oder abgetötet, sodass das Wasser wieder unter Hygienegesichtspunkten einwandfrei ist.The hygiene requirements for the drinking water supply of buildings or building complexes have increased significantly in recent years. The reason for this is the realization that standing water in the building's drinking water network for a long period of time, which is also referred to as stagnant water, can lead to the undesirable formation of germs. In this context, legionella or similar germs pose a health risk. Consequently, the relevant building drinking water network has been flushed regularly, which is referred to here as "hygiene flushing". Depending on the rinsing strategy, the germs are rinsed out, decimated and/or killed so that the water is again impeccable from a hygiene point of view.

Ein bekanntes Verfahren zum Betreiben eines Gebäude-Trinkwassernetzwerks ( DE 93 13 983 U1 ) betrifft das automatische Spülen des Gebäude-Trinkwassernetzwerks durch die automatische Betätigung elektrisch ansteuerbarer Wasserauslassstellen. Die Sanitärarmaturen sind über ein Datenbussystem mit einer in dem betreffenden Gebäude angeordneten Steuerung gekoppelt, sodass ein in der Steuerung gespeicherter Spülplan automatisch abgearbeitet werden kann. Das Bussystem zwischen der Steuerung und den Sanitärarmaturen ist über Zwischensteuerungen strukturiert, was insbesondere bei komplexen Gebäude-Trinkwassernetzwerken zu einem entsprechend komplexen, steuerungstechnischen Aufbau führt. Dies bedeutet auch, dass eine gebäudetechnische Erweiterung stets mit einer entsprechenden, steuerungstechnischen Herausforderung einhergeht.A known method of operating a building potable water network ( DE 93 13 983 U1 ) relates to the automatic flushing of the building's drinking water network through the automatic actuation of electrically controllable water outlet points. The sanitary fittings are coupled via a data bus system to a controller arranged in the relevant building, so that a flushing plan stored in the controller can be processed automatically. The bus system between the control and the sanitary fittings is structured via intermediate controls, which leads to a correspondingly complex control structure, particularly in the case of complex building drinking water networks. This also means that a building technology extension is always accompanied by a corresponding control technology challenge.

Hinzu kommt, dass eine sachgerechte Auslegung der Rechenleistung der Steuerung bei dem bekannten Verfahren kaum möglich ist, da die benötigte Rechenleistung bei sich verändernden Hygieneanforderungen einerseits und bei sich verändernden gebäudetechnischen Anforderungen andererseits laufend ändert.In addition, an appropriate design of the computing power of the controller is hardly possible with the known method, since the required Computing power changes constantly with changing hygiene requirements on the one hand and with changing building technology requirements on the other.

Schließlich ist es bei dem bekannten Verfahren so, dass das Gebäude-Trinkwassernetzwerk insoweit autark arbeitet, als Informationen von außen, beispielsweise Informationen von parallel zu betreibenden Gebäude-Trinkwassernetzwerken, bei der Umsetzung des Hygienespülens nicht herangezogen werden. Mit diesem Informationsdefizit besteht ein beträchtliches Optimierungspotential im Hinblick auf die Qualität beim Hygienespülen.Finally, in the case of the known method, the building drinking water network works autonomously to the extent that information from outside, for example information from building drinking water networks to be operated in parallel, is not used in the implementation of hygiene flushing. With this lack of information, there is considerable optimization potential with regard to the quality of hygienic dishwashing.

Der Erfindung liegt das Problem zu Grunde, das bekannte Verfahren zum Betreiben eines Gebäude-Trinkwassernetzwerks derart auszugestalten und weiterzubilden, dass das Hygienespülen mit geringem steuerungstechnischem Aufwand optimiert wird.The invention is based on the problem of designing and developing the known method for operating a building's drinking water network in such a way that the hygienic flushing is optimized with little outlay on control technology.

Das obige Problem wird bei einem Verfahren zum Betreiben mindestens eines Gebäude-Trinkwassernetzwerks mit den Merkmalen von Anspruch 1 gelöst.The above problem is solved with a method for operating at least one building drinking water network with the features of claim 1.

Zunächst einmal wird vorgeschlagen, dass das Gebäude-Trinkwassernetzwerk mittels eines internetbasierten Cloud-Serversystems betrieben wird. Bei einem solchen Cloud-Server-System handelt es sich um ein Serversystem, das räumlich unabhängig von dem zu betreibenden Gebäude-Trinkwassernetzwerk ist, da es mit dem Gebäude-Trinkwassernetzwerk über das Internet kommuniziert. Vorzugsweise stellt das Cloud-Serversystem gerade die Rechenleistung zur Verfügung, die von dem Gebäude-Trinkwassernetzwerk benötigt wird. Ferner hat das Cloud-Serversystem über das Internet Zugang zu Informationen von externen Datenquellen, auf deren Basis sich das Hygienespülen nach verschiedenen Kriterien optimieren lässt. Ein Beispiel hierfür sind Wetterinformationen, die Aufschluss darüber geben, ob die Keimbildung in dem Gebäude-Trinkwassernetzwerk wetterbedingt unterstützt wird, was ein verstärktes Hygienespülen zur Folge haben sollte.First of all, it is proposed that the building drinking water network is operated using an internet-based cloud server system. Such a cloud server system is a server system that is spatially independent of the building's drinking water network to be operated, since it communicates with the building's drinking water network via the Internet. The cloud server system preferably makes available the computing power that is required by the building's drinking water network. Furthermore, the cloud server system has access to information from external data sources via the Internet, on the basis of which hygienic flushing can be optimized according to various criteria. An example of this is weather information, which provides information on whether nucleation in the building drinking water network is weather-supported, which should result in increased hygienic flushing.

Das Gebäude-Trinkwassernetzwerk ist mit als Wasserauslassstellen ausgestalteten Sanitärarmaturen ausgestattet, die jeweils ein elektrisch ansteuerbares Wasserauslassventil und eine mobilfunkfähige Armatursteuerung aufweisen. Den Sanitärarmaturen ist es also jeweils möglich, über eine Mobilfunkverbindung zu kommunizieren. Damit ergibt sich bereits strukturell der Vorteil, dass eine Erweiterung oder Reduzierung des Gebäude-Trinkwassernetzwerks steuerungstechnisch unproblematisch ist.The building's drinking water network is equipped with sanitary fittings designed as water outlet points, each of which has an electrically controllable water outlet valve and a mobile radio-capable fitting control. So it is the sanitary fittings in each case possible to communicate via a cellular connection. This results in the structural advantage that an extension or reduction of the building's drinking water network is unproblematic in terms of control technology.

Vorschlagsgemäß werden von dem Cloud-Serversystem Kommunikationsobjekte in Form von Hygienespülanweisungen nach einer Hygienespülstrategie erzeugt. Für die Erzeugung der Hygienespülanweisungen nach der Hygienespülstrategie liegen also auch alle oben genannten Informationen aus externen Datenquellen vor, sodass die Erzeugung der Hygienespülanweisungen entsprechend optimiert und angepasst auf die jeweils aktuellen Informationen stattfinden kann.According to the proposal, communication objects in the form of hygiene flushing instructions are generated by the cloud server system according to a hygiene flushing strategy. For the generation of the hygiene flushing instructions according to the hygiene flushing strategy, all the above-mentioned information from external data sources is also available, so that the generation of the hygiene flushing instructions can be optimized and adapted to the current information.

Die so erzeugten Hygienespülanweisungen werden dann an die jeweilige Armatursteuerung über eine Mobilfunkverbindung zwischen einem öffentlichen Mobilfunk-Access-Point und der Armatursteuerung übermittelt. Interessant dabei ist die Tatsache, dass eine Mobilfunkverbindung zwischen einem öffentlichen Mobilfunk-Access-Point und der Armatursteuerung vorgesehen ist. Bei dem Mobilfunk-Access-Point handelt es sich um einen Gateway zwischen dem Mobilfunknetz und dem Internet. Hinsichtlich der Mobilfunkverbindung ist vorschlagsgemäß also ein dezentraler Ansatz gewählt worden, bei dem jede Sanitärarmatur für sich genommen eine Mobilfunkverbindung zu dem betreffenden, öffentlichen Mobilfunk-Access-Point aufbaut.The hygiene flushing instructions generated in this way are then transmitted to the respective faucet control via a mobile radio connection between a public mobile radio access point and the faucet control. What is interesting is the fact that a mobile phone connection is provided between a public mobile phone access point and the faucet control. The cellular access point is a gateway between the cellular network and the Internet. With regard to the mobile phone connection, a decentralized approach was chosen according to the proposal, in which each sanitary fitting sets up a mobile phone connection to the public mobile phone access point in question.

Der Begriff "öffentlich" bedeutet vorliegend lediglich, dass der Mobilfunk-Access-Point auch für Mobilfunk-Teilnehmer zugänglich ist, die dem Gebäude-Trinkwassernetzwerk nicht angehören.In the present case, the term "public" merely means that the mobile radio access point is also accessible to mobile radio subscribers who do not belong to the building's drinking water network.

Die von dem Cloud-Serversystem erzeugten und übermittelten Hygienespülanweisungen sind von der jeweiligen Armatursteuerung durch eine Ansteuerung des jeweiligen Wasserauslassventils umsetzbar. Dies bedeutet, dass das vorschlagsgemäße Verfahren nicht auf den Verfahrensschritt der Umsetzung der Hygienespülanweisungen seitens der Armatursteuerungen beschränkt ist. Es geht hier zunächst lediglich um die Umsetzbarkeit der Hygienespülanweisungen seitens der Armatursteuerungen. Nur vorzugsweise ist es vorgesehen, dass das vorschlagsgemäße Verfahren den Verfahrensschritt der Umsetzung der von dem Cloud-Serversystem erzeugten und übermittelten Hygienespülanweisungen durch eine Ansteuerung des jeweiligen Wasserauslassventils umfasst.The hygiene flushing instructions generated and transmitted by the cloud server system can be implemented by the respective faucet controller by activating the respective water outlet valve. This means that the proposed method is not limited to the method step of implementing the hygiene flushing instructions on the part of the valve controls. Initially, it is only a question of the feasibility of the hygiene flushing instructions on the part of the valve controls. Provision is only preferably made for the proposed method to include the method step of implementing the hygiene flushing instructions generated and transmitted by the cloud server system by controlling the respective water outlet valve.

Das vorschlagsgemäße Verfahren kombiniert einen zentralen Steueraspekt, nämlich die Steuerung aller Sanitärarmaturen durch ein und dasselbe Cloud-Serversystem, mit einem dezentralen Steueraspekt, nämlich der Realisierung einer Mobilfunkverbindung für jede einzelne Sanitärarmatur.The proposed method combines a central control aspect, namely the control of all sanitary fittings by one and the same cloud server system, with a decentralized control aspect, namely the implementation of a mobile phone connection for each individual sanitary fitting.

Der letztgenannte, dezentrale Steueraspekt sorgt, wie weiter oben schon angedeutet, für eine Flexibilität bei der Auslegung des Gebäude-Trinkwassernetzwerks, ohne dass steuerungstechnisch irgendwelche Restriktionen zu erwarten sind. Dies geht auf die Überlegung zurück, dass jede Sanitärarmatur die Kommunikation zu dem Mobilfunk-Access-Point autark organisiert. Auch ein Nachrüsten eines bestehenden Gebäude-Trinkwassernetzwerks ist damit unproblematisch.The latter, decentralized control aspect, as already indicated above, ensures flexibility in the design of the building's drinking water network without any restrictions being expected in terms of control technology. This goes back to the idea that each sanitary fitting organizes communication with the mobile radio access point independently. Retrofitting an existing building drinking water network is also unproblematic.

Der erstgenannte, zentrale Steueraspekt ermöglicht aufgrund des internetbasierten Cloud-Serversystems die Nutzung für alle Sanitärarmaturen, die von dem Cloud-Serversystem betrieben werden, sodass sich eine Optimierung des Hygienespülens in einer Form ergibt, die bislang nur mit großem Aufwand möglich war.Due to the Internet-based cloud server system, the first-mentioned, central control aspect enables use for all sanitary fittings that are operated by the cloud server system, so that hygienic flushing is optimized in a way that was previously only possible with great effort.

Schließlich ergeben sich durch den zentralen Steueraspekt des vorschlagsgemäßen Verfahrens die zusätzlichen Vorteile einer für alle Sanitärarmaturen einheitlichen Softwareverwaltung, einer für alle Sanitärarmaturen einheitlichen Fehlerdiagnose und einer für alle Sanitärarmaturen einheitlichen Notfallfunktion, wie des notfallbedingten Abschaltens aller Sanitärarmaturen.Finally, the central control aspect of the proposed method results in the additional advantages of a uniform software management for all sanitary fittings, a uniform error diagnosis for all sanitary fittings and an emergency function, such as the emergency shutdown of all sanitary fittings.

Die bevorzugten Ausgestaltungen gemäß den Ansprüchen 2 und 3 betreffen strukturelle Aspekte insbesondere für den Fall, dass das Cloud-Serversystem mindestens zwei räumlich voneinander getrennte Gebäude-Trinkwassernetzwerke betreibt. Dann ist es in einer bevorzugten Variante von Anspruch 2 so, dass Betriebsinformationen des einen Gebäude-Trinkwassernetzwerks für das Betreiben eines anderen Gebäude-Trinkwassernetzwerks genutzt werden können. Hier zeigt sich ein wichtiger Vorteil des zentralen Cloud-Serversystems, nämlich der Vorteil der Verfügbarkeit von Informationen, die nur bei einer zentralen Struktur möglich ist.The preferred configurations according to claims 2 and 3 relate to structural aspects in particular for the case that the cloud server system operates at least two spatially separate building drinking water networks. Then, in a preferred variant of claim 2, operating information from one building's drinking water network can be used to operate another building's drinking water network. This shows an important advantage of the central cloud server system, namely the advantage of the availability of information, which is only possible with a central structure.

Die weiter bevorzugten Ausgestaltungen gemäß den Ansprüchen 4 und 5 betreffen Einzelheiten zu den Hygienespülanweisungen. Mit Anspruch 4 wird insbesondere klargestellt, dass es sich bei den Hygienespülanweisungen um eine unmittelbare Anweisung im Sinne eines Schaltbefehls, aber auch um eine mittelbare Anweisung im Sinne einer Zeitangabe für die betreffende Hygienespülaktion handeln kann.The further preferred embodiments according to claims 4 and 5 relate to details of the hygiene flushing instructions. Claim 4 makes it particularly clear that the hygiene flushing instructions can be direct instructions in the sense of a switching command, but also indirect instructions in the sense of specifying a time for the relevant hygiene flushing action.

Die ebenfalls bevorzugten Ausgestaltungen gemäß den Ansprüchen 6 und 7 betreffen die Möglichkeit der bidirektionalen Datenübertragung zwischen dem Cloud-Serversystem und den Armatursteuerungen, indem die Armatursteuerungen jeweils Armatur-Kommunikationsobjekte erzeugen und über die jeweilige Mobilfunkverbindung an das Cloud-Serversystem übermitteln. In besonders bevorzugter Ausgestaltung gemäß Anspruch 6 repräsentieren die Armatur-Kommunikationsobjekte Statusinformationen und/oder Armatur-Sensorinformationen und/oder Benutzereingaben. Andere Arten von Armatur-Kommunikationsobjekten sind denkbar.The likewise preferred embodiments according to claims 6 and 7 relate to the possibility of bidirectional data transmission between the cloud server system and the faucet controls, in that the faucet controls each generate faucet communication objects and transmit them to the cloud server system via the respective mobile radio connection. In a particularly preferred embodiment according to claim 6, the dashboard communication objects represent status information and/or dashboard sensor information and/or user inputs. Other types of valve communication objects are conceivable.

Mit der obigen, bidirektionalen Kommunikation zwischen dem Cloud-Server-system und den Armatursteuerungen lässt sich eine Rückkopplung von den Armatursteuerungen zu dem Cloud-Serversystem hin aufbauen, die von einer einfachen Bestätigung der Umsetzung einer Hygienespülanweisung bis hin zu einer regelungstechnischen Rückkopplung reicht.With the above, bidirectional communication between the cloud server system and the faucet controls, a feedback from the faucet controls to the cloud server system can be established, which ranges from a simple confirmation of the implementation of a hygiene flushing instruction to a control-technical feedback.

Bei der besonders bevorzugten Ausgestaltung gemäß Anspruch 8 wird auf eine zwischengeschaltete Datenverarbeitung zwischen dem Cloud-Serversystem und den Sanitärarmaturen vollständig verzichtet. Dies bedeutet, dass auf eine datentechnische Verarbeitung der Kommunikationsobjekte, die über Maßnahmen zum Datentransport hinausgehen, verzichtet wird. Dies entspricht einer konsequenten Umsetzung des oben angesprochenen, zentralen Steueraspekts des vorschlagsgemäßen Verfahrens.In the particularly preferred embodiment according to claim 8, there is no need for any intermediate data processing between the cloud server system and the sanitary fittings. This means that there is no data processing of the communication objects that goes beyond measures for data transport. This corresponds to a consistent implementation of the central control aspect of the proposed procedure mentioned above.

Eine bevorzugte Möglichkeit für die Übermittlung von Benutzer-Kommunikationsobjekten ist Gegenstand von Anspruch 9. Hier wird vorgeschlagen, dass hierfür ein internetbasierter Benutzerterminal vorgesehen ist, der mit dem Cloud-Serversystem über eine Internetverbindung kommuniziert. Damit ist es dem Benutzer möglich, unabhängig von seinem Aufenthaltsort auf das Cloud-Serversystem zuzugreifen. Dies ist mit einem besonders hohen Benutzungskomfort verbunden.A preferred option for the transmission of user communication objects is the subject of claim 9. Here it is proposed that an internet-based user terminal is provided for this purpose, which communicates with the cloud server system via an internet connection. This enables the user to access the cloud server system regardless of where they are. This is associated with a particularly high level of user comfort.

Die weiter bevorzugten Ausgestaltungen gemäß den Ansprüchen 10 bis 13 betreffen die Erzeugung eines Hygienespülplans aus Hygienespülaktionen mittels des Cloud-Serversystems (Anspruch 10). Die Basis hierfür bildet die Hygienespülstrategie, die je nach Gebäude-Trinkwassernetzwerk und insbesondere in Abhängigkeit von verschiedenen Umgebungsbedingungen wie der Umgebungstemperatur unterschiedlich gewählt werden kann.The further preferred configurations according to claims 10 to 13 relate to the generation of a hygiene flushing plan from hygiene flushing actions using the cloud server system (claim 10). The basis for this is the hygiene flushing strategy, which can be selected differently depending on the building's drinking water network and in particular depending on various environmental conditions such as the ambient temperature.

Eine besonders einfache Optimierung des Hygienespülplans ist Gegenstand von Anspruch 14, bei dem der Hygienespülplan nach einem vorbestimmten Optimierungskriterium, vorzugsweise nach dem Optimierungskriterium des Hygienezustands, des Wasserverbrauchs oder des Energieverbrauchs, optimiert wird. Auch diese Optimierung des Hygienespülplans ist mit dem zentralen Steueraspekt des vorschlagsgemäßen Verfahrens besonders leicht umsetzbar.A particularly simple optimization of the hygiene flushing plan is the subject of claim 14, in which the hygiene flushing plan is optimized according to a predetermined optimization criterion, preferably according to the optimization criterion of the state of hygiene, the water consumption or the energy consumption. This optimization of the hygiene flushing plan is also particularly easy to implement with the central control aspect of the proposed method.

Eine weitere Steigerung des Benutzungskomforts lässt sich gemäß Anspruch 15 dadurch erreichen, dass von dem Cloud-Serversystem eine Statusinformation betreffend das zu betreibende Gebäude-Trinkwassernetzwerk erzeugt und, hier und vorzugsweise über den obigen Benutzerterminal, ausgegeben wird. Damit ist der Benutzer, wiederum unabhängig von seinem Aufenthaltsort, über den jeweiligen Status des Gebäude-Trinkwassernetzwerks informiert.A further increase in user comfort can be achieved according to claim 15 in that status information relating to the building drinking water network to be operated is generated by the cloud server system and is output here and preferably via the above user terminal. This means that the user is informed about the current status of the building's drinking water network, regardless of where he is.

Nach einer weiteren Lehre, der eigenständige Bedeutung zukommt, wird ein Hygienesteuersystem zur Durchführung des vorschlagsgemäßen Verfahrens als solches beansprucht.According to a further teaching, which is of independent importance, a hygiene control system for carrying out the proposed method is claimed as such.

Wesentlich nach der weiteren Lehre ist die Tatsache, dass das Hygienesteuersystem das obige Cloud-Serversystem aufweist, das zur Durchführung des vorschlagsgemäßen Verfahrens eingerichtet ist. Ein obiges Gebäude-Trinkwassernetzwerk als solches ist dem Hygienesteuersystem nicht zuzurechnen. Auf alle Ausführungen zu dem vorschlagsgemäßen Verfahren gemäß der erstgenannten Lehre darf verwiesen werden.According to the further teaching, the fact that the hygiene control system has the above cloud server system, which is set up to carry out the proposed method, is essential. A building potable water network above as such is not attributable to the hygiene control system. To all Statements on the proposed method according to the first-mentioned teaching may be referred to.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. In der Zeichnung zeigt

The invention is explained in more detail below with reference to a drawing that merely shows an exemplary embodiment. In the drawing shows
1
in a schematic representation of two building drinking water networks, which are operated by an internet-based cloud server system according to a proposed method and
2
a proposed method for operating the in 1 illustrated building drinking water networks in a flow chart.

Das vorschlagsgemäße Verfahren dient dem Betreiben mindestens eines Gebäude-Trinkwassernetzwerks, hier dem Betreiben eines ersten Gebäude-Trinkwassernetzwerks 1 und dem Betreiben eines zweiten Gebäude-Trinkwassernetzwerks 2. Grundsätzlich kann das vorschlagsgemäße Verfahren zum Betreiben einer Mehrzahl von Gebäude-Trinkwassernetzwerken 1, 2 vorgesehen sein. Alle Ausführungen zu den beiden dargestellten Gebäude-Trinkwassernetzwerken 1, 2 gelten für alle weiteren, eventuell vorgesehenen Gebäude-Trinkwassernetzwerke 1, 2 entsprechend.The proposed method is used to operate at least one building drinking water network, here the operation of a first building drinking water network 1 and the operation of a second building drinking water network 2. In principle, the proposed method for operating a plurality of building drinking water networks 1, 2 can be provided. All statements relating to the two building drinking water networks 1, 2 shown apply accordingly to all other building drinking water networks 1, 2 that may be provided.

Das erste Gebäude-Trinkwassernetzwerk 1 ist mit Sanitärarmaturen 3-6 ausgestattet, während das zweite Gebäude-Trinkwassernetzwerk 2 mit nur einer einzigen, exemplarisch dargestellten Sanitärarmatur 7 ausgestattet ist. Im Folgenden wird das vorschlagsgemäße Verfahren in erster Linie anhand des ersten Gebäude-Trinkwassernetzwerks 1 erläutert, was nicht beschränkend zu verstehen ist.The first building drinking water network 1 is equipped with sanitary fittings 3-6, while the second building drinking water network 2 is equipped with only a single sanitary fitting 7, shown as an example. The proposed method is explained below primarily on the basis of the first building drinking water network 1, which is not to be understood as limiting.

Bei den Sanitärarmaturen 3-7 kann es sich um jedwede Sanitärarmatur handeln, die ein Wasserauslassventil zum Auslassen von Trinkwasser aufweist. Dazu gehören beispielsweise Waschtischarmaturen, Duscheinrichtungen, Toiletten, Urinale, o. dgl. Nicht dazu gehören entsprechend alle Arten von Absperrventilen, die keinen Wasserauslass erlauben.The sanitary fittings 3-7 can be any sanitary fitting that has a water outlet valve for letting out drinking water. This includes, for example, washbasin fittings, shower facilities, toilets, urinals, or the like. Correspondingly, this does not include all types of shut-off valves that do not allow water to escape.

Fig. 1 zeigt, dass ein internetbasiertes Cloud-Serversystem 8 vorgesehen ist, das den zentralen Steueraspekt der vorschlagsgemäßen Lösung repräsentiert, wie noch gezeigt wird. 1 shows that an internet-based cloud server system 8 is provided, which represents the central control aspect of the proposed solution, as will be shown.

Die Sanitärarmaturen 3-7 weisen jeweils ein elektrisch ansteuerbares Wasserauslassventil 3a-7a und eine mobilfunkfähige Armatursteuerung 3b-7b auf. "Elektrisch ansteuerbar" bedeutet vorliegend ganz allgemein, dass die als Wasserauslassstellen ausgestalteten Sanitärarmaturen 3-7 dafür eingerichtet sind, elektrisch durch eine entsprechende Ansteuerung durch die Armatursteuerung 3b-7b geöffnet und geschlossen zu werden, um das Auslassen von Trinkwasser zu erlauben oder zu sperren.The sanitary fittings 3-7 each have an electrically controllable water outlet valve 3a-7a and a mobile radio-capable fitting control 3b-7b. "Electrically controllable" means here in general that the sanitary fittings 3-7 designed as water outlet points are set up to be opened and closed electrically by a corresponding control by the fitting control 3b-7b in order to allow or block the discharge of drinking water.

Der Begriff "internetbasiert" in Verbindung mit dem Cloud-Serversystem 8 bedeutet vorliegend, dass das Cloud-Serversystem 8 eingerichtet ist, über eine Internetverbindung zu kommunizieren.In the present case, the term “internet-based” in connection with the cloud server system 8 means that the cloud server system 8 is set up to communicate via an internet connection.

Nach dem vorschlagsgemäßen Verfahren werden, wie in Fig. 2 gezeigt, von dem Cloud-Serversystem 8 Kommunikationsobjekte in Form von Hygienespülanweisungen 9 nach einer Hygienespülstrategie 10 erzeugt (Verfahrensschritt A in Fig. 2). Die Hygienespülstrategie 10 ist von verschiedenen Einflussfaktoren abhängig, wie noch erläutert wird.According to the proposed method, as in 2 shown, generated by the cloud server system 8 communication objects in the form of hygiene flushing instructions 9 according to a hygiene flushing strategy 10 (method step A in 2 ). The hygiene flushing strategy 10 depends on various influencing factors, as will be explained below.

Die erzeugten Hygienespülanweisungen 9 werden an die jeweilige Armatursteuerung 3b-7b über eine Mobilfunkverbindung 3c-7c zwischen einem öffentlichen Mobilfunk-Access-Point 11 und der Armatursteuerung 3b-7b übermittelt (Verfahrensschritt B in Fig. 2). Schließlich ist es so, dass die empfangenen Hygienespülanweisungen 9 von der Armatursteuerung 3b-7b durch eine Ansteuerung des Wasserauslassventils 3a-7a umsetzbar sind, vorzugsweise umgesetzt werden (Verfahrensschritt C in Fig. 2).The generated hygiene flushing instructions 9 are transmitted to the respective fitting control 3b-7b via a mobile radio connection 3c-7c between a public mobile radio access point 11 and the fitting control 3b-7b (method step B in 2 ). Finally, it is the case that the hygiene flushing instructions 9 received can be implemented, preferably implemented, by the fitting control 3b-7b by activating the water outlet valve 3a-7a (method step C in 2 ).

Für die Realisierung der Mobilfunkverbindungen 3c-7c sind die Armatursteuerungen 3b-7b vorzugsweise mit einem LTE-Modul (Long Term Evolution Mobilfunkstandard), insbesondere mit einem Narrowband LTE-Modul ausgestattet. Andere Möglichkeiten der Realisierung der Mobilfunkverbindungen 3c-7c sind denkbar.In order to implement the mobile radio connections 3c-7c, the fitting controls 3b-7b are preferably equipped with an LTE module (Long Term Evolution mobile radio standard), in particular with a narrowband LTE module. Other possibilities for realizing the mobile radio connections 3c-7c are conceivable.

Es lässt sich der Darstellung gemäß Fig. 1 entnehmen, dass mittels des Cloud-Serversystems 8 mindestens zwei räumlich voneinander getrennte Gebäude-Trinkwassernetzwerke 1, 2 betrieben werden. Dabei ist es vorzugsweise so, dass von dem Cloud-Serversystem 8 während des Betreibens eines ersten Gebäude-Trinkwassernetzwerks 1 Betriebsinformationen erzeugt werden, die von dem Cloud-Serversystem 8 für das Betreiben eines zweiten Gebäude-Trinkwassernetzwerks 2 genutzt werden. Im einfachsten Fall bedeutet dies, dass von dem Cloud-Serversystem 8 die Hygienespülstrategie 10 des ersten Gebäude-Trinkwassernetzwerks dem Betreiben des zweiten Gebäude-Trinkwassernetzwerks 2 zu Grunde gelegt wird. Hier zeigt sich, wie oben angesprochen, der Vorteil des zentralen Steueransatzes der vorschlagsgemäßen Lösung.It can be shown in accordance with 1 see that by means of the cloud server system 8 at least two spatially separate building drinking water networks 1, 2 are operated. It is preferably the case that the cloud server system 8 generates operating information during the operation of a first building's drinking water network 1 , which is used by the cloud server system 8 for operating a second building's drinking water network 2 . In the simplest case, this means that the cloud server system 8 uses the hygienic flushing strategy 10 of the first building's drinking water network to operate the second building's drinking water network 2 . As mentioned above, this shows the advantage of the central control approach of the proposed solution.

In bevorzugter Ausgestaltung ist das zu betreibende Gebäude-Trinkwassernetzwerk 1, 2 einem Gebäude 12, 13 oder einem Gebäudekomplex zugeordnet. Hier und vorzugsweise ist es so, dass die zu betreibenden Gebäude-Trinkwassernetzwerke 1, 2 jeweils einem Gebäude 12, 13 oder einem Gebäudekomplex zugeordnet sind. Der Gebäudekomplex kann dabei beliebig definiert sein und ist nicht auf zusammenliegende Gebäude beschränkt. Insoweit ist der Begriff "Gebäudekomplex" weit zu verstehen. Insbesondere kann sich ein Gebäudekomplex demnach über international verteilte Gebäude erstrecken.In a preferred embodiment, the building drinking water network 1, 2 to be operated is assigned to a building 12, 13 or a building complex. Here, and preferably, the building drinking water networks 1, 2 to be operated are each assigned to a building 12, 13 or a building complex. The building complex can be defined arbitrarily and is not limited to adjacent buildings. In this respect, the term "building complex" is to be understood broadly. In particular, a building complex can accordingly extend over internationally distributed buildings.

Grundsätzlich können einzelne Gebäude-Trinkwassernetzwerke 1, 2 und/oder einzelne Sanitärarmaturen 3-7 in dem Cloud-Serversystem 8 zu logischen Gruppen zusammengefasst werden, die jeweils hinsichtlich vorbestimmter Gruppenregeln einheitlich angesteuert werden. Beispielsweise kann es vorgesehen sein, dass alle Sanitärarmaturen 3-7 einer logischen Gruppe in einheitlichen Spülzyklen gespült werden. Dies kann zusätzlich zum Hygienespülen vorgesehen sein, das lokal bedingt, beispielsweise durch lokal hohe Umgebungstemperaturen, ausgelöst wird.In principle, individual building drinking water networks 1, 2 and/or individual sanitary fittings 3-7 can be combined into logical groups in the cloud server system 8, which are each controlled uniformly with regard to predetermined group rules. For example, provision can be made for all sanitary fittings 3-7 in a logical group to be flushed in uniform flushing cycles. This can be provided in addition to the hygiene flushing, which is triggered locally, for example due to locally high ambient temperatures.

Die Kommunikation zwischen dem Cloud-Serversystem 8 und den Armatursteuerungen 3b-7b verläuft abschnittsweise internetbasiert und abschnittsweise mobilfunkbasiert. Fig. 1 zeigt, dass das Cloud-Serversystem 8 über eine Internetverbindung 14 mit dem Mobilfunk-Access-Point 11 kommuniziert, während der Mobilfunk-Access-Point 11 mit den Armatursteuerungen 3b-7b wie oben angesprochen über die Mobilfunkverbindungen 3c-7c kommuniziert. Interessant dabei ist die oben angesprochene Kombination des zentralen Steueraspekts mit dem dezentralen Steueraspekt.The communication between the cloud server system 8 and the valve controls 3b-7b runs in sections based on the Internet and in sections based on mobile communications. 1 shows that the cloud server system 8 communicates with the cellular access point 11 via an Internet connection 14, while the cellular access point 11 communicates with the faucet controls 3b-7b as above addressed communicated via the cellular connections 3c-7c. What is interesting here is the combination of the central control aspect with the decentralized control aspect mentioned above.

Die Hygienespülanweisungen 9 betreffen jeweils die Umsetzung mindestens einer Hygienespülaktion, bei der es sich beispielsweise um das Auslassen von Trinkwasser zu einem Hygienespülzeitpunkt über eine Hygienespüldauer handeln kann. Entsprechend umfassen die Hygienespülanweisungen 9 jeweils mindestens einen die umzusetzende Hygienespülaktion beschreibenden Hygienespülparameter. Insbesondere ist es vorzugsweise so, dass der mindestens eine Hygienespülparameter ein die Hygienespülaktion betreffender Hygienespülzeitpunkt, eine die Hygienespülaktion betreffende Hygienespüldauer o.dgl. ist. Dabei ist zu berücksichtigen, dass der Hygienespülzeitpunkt auch das sofortige Ansteuern des betreffenden Wasserauslassventils 3a-7a beschreiben kann. Dann handelt es sich bei den Hygienespülanweisungen 9 um nichts anderes als um Schaltbefehle für das Wasserauslassventil 3a-7a.The hygiene flushing instructions 9 each relate to the implementation of at least one hygiene flushing action, which can involve, for example, draining drinking water at a hygiene flushing time over a hygiene flushing duration. Accordingly, the hygiene flushing instructions 9 each include at least one hygiene flushing parameter describing the hygiene flushing action to be implemented. In particular, it is preferably the case that the at least one hygiene flushing parameter is a hygiene flushing time relating to the hygiene flushing action, a hygiene flushing duration or the like relating to the hygiene flushing action. is. It must be taken into account here that the hygiene flushing time can also describe the immediate actuation of the relevant water outlet valve 3a-7a. Then the hygiene flushing instructions 9 are nothing more than switching commands for the water outlet valve 3a-7a.

Vorzugsweise übermittelt das Cloud-Serversystem 8 neben den Hygienespülanweisungen 9 zusätzlich weitere Cloud-Kommunikationsobjekte über die jeweilige Mobilfunkverbindung 3c-7c an die jeweilige Armatursteuerung 3b-7b. Hierzu gehört beispielsweise ein Konfigurationsdatensatz, über den sich die jeweilige Armatursteuerung 3b-7b in einen vorbestimmten Betriebsmodus bringen lässt. Solche Betriebsmodi können beispielsweise ein Komfortmodus, ein Energiesparmodus, ein Wassersparmodus o. dgl. sein.In addition to the hygiene flushing instructions 9, the cloud server system 8 preferably also transmits further cloud communication objects via the respective mobile radio connection 3c-7c to the respective fitting control 3b-7b. This includes, for example, a configuration data set, via which the respective fitting control 3b-7b can be brought into a predetermined operating mode. Such operating modes can be, for example, a comfort mode, an energy-saving mode, a water-saving mode or the like.

Der Konfigurationsdatensatz kann grundsätzlich nur einen einzigen Konfigurationsparameter oder aber mehrere Konfigurationsparameter umfassen.In principle, the configuration data record can comprise only a single configuration parameter or else a plurality of configuration parameters.

Je nach Anwendungsfall sind zahlreiche weitere Cloud-Kommunikationsobjekte denkbar, die Anweisungen aller Art umfassen können. Beispielsweise kann ein Cloud-Kommunikationsobjekt eine Not-Aus-Anweisung repräsentieren, bei deren Empfang die Armatursteuerungen 3b-7b das Wasserauslassventil 3a-7a schließen.Depending on the application, numerous other cloud communication objects are conceivable, which can include instructions of all kinds. For example, a cloud communication object can represent an emergency stop instruction, upon receipt of which the faucet controls 3b-7b close the water outlet valve 3a-7a.

Wie weiter oben erläutert, ist vorzugsweise eine bidirektionale Kommunikation zwischen dem Cloud-Serversystem 8 und den Armatursteuerungen 3b-7b vorgesehen. Dabei ist es vorzugsweise so, dass von den Armatursteuerungen 3b-7b Armatur-Kommunikationsobjekte erzeugt und über die jeweilige Mobilfunkverbindung 3c-7c an das Cloud-Serversystem 8 übermittelt werden. Solche Armatur-Kommunikationsobjekte können beispielsweise Statusinformationen und/oder Armatur-Sensorinformationen und/oder Benutzereingaben repräsentieren. Die Statusinformationen können beispielsweise einen Verbindungsstatus zu dem Mobilfunk-Access-Point 11, den Batteriestand einer Versorgungsbatterie der Armatursteuerung 3b-7b oder die Bestätigung des Abschlusses einer Spülaktion betreffen.As explained above, bidirectional communication is preferably provided between the cloud server system 8 and the fitting controls 3b-7b. It is preferably the case that the fitting controls 3b-7b generate fitting communication objects and transmit them to the cloud server system 8 via the respective mobile radio connection 3c-7c. Such dashboard communication objects can represent, for example, status information and/or dashboard sensor information and/or user inputs. The status information can relate, for example, to a connection status to the mobile radio access point 11, the battery level of a supply battery for the fitting control 3b-7b, or confirmation of the completion of a rinsing action.

Zur Erzeugung der Armatur-Sensorinformationen weist zumindest ein Teil der Sanitärarmaturen 3-7 mindestens einen Sensor 15 auf, der beispielhaft an der Sanitärarmatur 5 gezeigt ist. Der Sensor 15, der hier und vorzugsweise als Temperatursensor ausgestaltet ist, erzeugt eine Armatur-Sensorinformation, die als Armatur-Kommunikationsobjekt über die Mobilfunkverbindung 3c-7c an das Cloud-Serversystem 8 übermittelt wird.To generate the fitting sensor information, at least some of the sanitary fittings 3-7 have at least one sensor 15, which is shown as an example on the sanitary fitting 5. The sensor 15, which is designed here and preferably as a temperature sensor, generates fitting sensor information which is transmitted to the cloud server system 8 as a fitting communication object via the mobile radio connection 3c-7c.

Die Darstellung gemäß Fig. 1 zeigt, dass die Cloud-Kommunikationsobjekte und/oder die Armatur-Kommunikationsobjekte ohne eine zwischengeschaltete Datenverarbeitung zwischen dem Cloud-Serversystem 8 und den Sanitärarmaturen 3-7 übermittelt werden. In der Internetverbindung 14 und in den Mobilfunkverbindungen 3c-7c sowie in dem lediglich ein Gateway darstellenden Mobil-Access-Point 11 findet keine Datenverarbeitung statt, die über Maßnahmen zum Datentransport hinausgeht, sodass auf eine diesbezügliche Steuerungshardware verzichtet werden kann.The representation according to 1 shows that the cloud communication objects and/or the fitting communication objects are transmitted between the cloud server system 8 and the sanitary fittings 3-7 without any intermediate data processing. In the Internet connection 14 and in the mobile radio connections 3c-7c as well as in the mobile access point 11, which is merely a gateway, no data processing takes place that goes beyond measures for data transport, so that the relevant control hardware can be dispensed with.

Um eine Kommunikation mit dem Benutzer realisieren zu können, sind vorzugsweise Benutzer-Kommunikationsobjekte vorgesehen, die zwischen einem internetbasierten Benutzerterminal 16, 17 und dem Cloud-Serversystem 8 über eine Internetverbindung 18 übermittelt werden. Vorzugsweise werden die Benutzer-Kommunikationsobjekte in Form von Benutzereingaben eines Benutzers und/oder Benutzerausgaben an den Benutzer über den Benutzerterminal 16, 17 umgesetzt. Fig. 1 zeigt beispielhaft einen ersten Benutzerterminal 16 in Form eines Personal Computers und einen zweiten Benutzerterminal 17 in Form eines Handheld-Devices, hier eines Smartphones. Vorteilhaft ist hier die Internetanbindung des Benutzerterminals 16, 17, sodass eine Kommunikation mit dem Cloud-Serversystem 8 unabhängig vom Aufenthaltsort des Benutzers über die Internetverbindung 18 möglich ist.In order to be able to communicate with the user, user communication objects are preferably provided, which are transmitted between an Internet-based user terminal 16, 17 and the cloud server system 8 via an Internet connection 18. The user communication objects are preferably implemented in the form of user input from a user and/or user output to the user via the user terminal 16, 17. 1 shows an example of a first user terminal 16 in the form of a personal computer and a second user terminal 17 in the form of a handheld device, here a smartphone. The Internet connection of the user terminals 16, 17 is advantageous here, so that communication is possible with the cloud server system 8 via the Internet connection 18 regardless of where the user is located.

Der obigen Erzeugung der Hygienespülanweisungen liegt vorzugsweise die Erzeugung eines Hygienespülplans zu Grunde, der sich aus Hygienespülaktionen für die einzelnen Sanitärarmaturen 3-7 zusammensetzt. Der Hygienespülplan wird nach der Hygienespülstrategie 10 erzeugt. Nach dem Hygienespülplan werden die Hygienespülaktionen Zeit-basiert und/oder Ereignis-basiert ausgelöst.The above generation of the hygiene flushing instructions is preferably based on the generation of a hygiene flushing plan which is composed of hygiene flushing actions for the individual sanitary fittings 3-7. The hygienic flushing plan is generated according to the hygienic flushing strategy 10. According to the hygiene flushing plan, the hygiene flushing actions are triggered based on time and/or events.

In besonders bevorzugter Ausgestaltung ist es so, dass der Hygienespülplan nach der Hygienespülstrategie in Abhängigkeit von lokalen Zustandsinformationen 19 betreffend den Zustand des zu betreibenden Gebäude-Trinkwassernetzwerks 1, 2, hier und vorzugsweise von Armatur-Sensorinformationen, erzeugt wird.In a particularly preferred embodiment, the hygiene flushing plan is generated according to the hygiene flushing strategy as a function of local status information 19 relating to the status of the building's drinking water network 1, 2 to be operated, here and preferably of fittings sensor information.

Die vorschlagsgemäße Verwendung eines Cloud-Serversystems zeigt sich in besonders vorteilhafter Weise, wenn von dem Cloud-Serversystem 8 globale Umgebungsinformationen 20, hier und vorzugsweise Wetterinformationen betreffend das räumliche Territorium des zu betreibenden Gebäude-Trinkwassernetzwerks 1, 2 und/oder wasserwerksseitige Wasserzustandsinformationen, empfangen werden, wobei der Hygienespülplan nach der Hygienespülstrategie in Abhängigkeit von den globalen Umgebungsinformationen 20 erzeugt wird.The proposed use of a cloud server system is particularly advantageous if the cloud server system 8 receives global environmental information 20, here and preferably weather information relating to the spatial territory of the building drinking water network 1, 2 to be operated and/or water status information from the water works , The hygiene flushing plan being generated according to the hygiene flushing strategy as a function of the global environmental information 20 .

Eine weitere Optimierung des Hygienespülens lässt sich dadurch erreichen, dass von dem Cloud-Serversystem 8 aus dem zeitlichen Verlauf der lokalen Zustandsinformationen 19 und/oder der globalen Umgebungsinformationen 20 und/oder der Benutzereingaben eine Historieninformation erzeugt wird, wobei der Hygienespülplan nach der Hygienespülstrategie in Abhängigkeit von der Historieninformation erzeugt wird. Hierdurch lässt sich mittels des Cloud-Serversystems 8 die Betriebshistorie des betreffenden Gebäude-Trinkwassernetzwerks 1, 2 in die Erzeugung der Hygienespülanweisungen einbeziehen.A further optimization of the hygiene flushing can be achieved in that history information is generated by the cloud server system 8 from the time profile of the local status information 19 and/or the global environmental information 20 and/or the user inputs, with the hygiene flushing plan depending on the hygiene flushing strategy generated from the history information. In this way, the operating history of the relevant building drinking water network 1, 2 can be included in the generation of the hygiene flushing instructions by means of the cloud server system 8.

In weiter bevorzugter Ausgestaltung wird von dem Cloud-Serversystem 8 der Hygienespülplan nach einem vorbestimmten Optimierungskriterium optimiert.In a further preferred embodiment, the hygiene flushing plan is optimized by the cloud server system 8 according to a predetermined optimization criterion.

Hier kann ein Regelkreis realisiert sein, dessen Führungsgröße dem Optimierungskriterium entspricht. Das Optimierungskriterium kann beispielsweise den Hygienezustand, den Wasserverbrauch, den Energieverbrauch o. dgl. des zu betreibenden Gebäude-Trinkwassernetzwerks 1, 2 betreffen.A control loop can be implemented here whose reference variable corresponds to the optimization criterion. The optimization criterion can, for example, relate to the state of hygiene, the water consumption, the energy consumption or the like of the building's drinking water network 1, 2 to be operated.

Ein wichtiger Bestandteil des vorschlagsgemäßen Verfahrens ist eine effiziente Information des Benutzers über den Status der zu betreibenden Gebäude-Trinkwassernetzwerke 1, 2. Entsprechend ist es hier und vorzugsweise vorgesehen, dass von dem Cloud-Serversystem 8 eine Statusinformation betreffend das zu betreibende Gebäude-Trinkwassernetzwerk 1, 2 erzeugt wird. In besonders bevorzugter Ausgestaltung betrifft die Statusinformation den Hygienezustand, den Wasserverbrauch, den Energieverbrauch o. dgl. des zu betreibenden Gebäude-Trinkwassernetzwerks 1, 2.An important part of the proposed method is efficient information for the user about the status of the building drinking water networks 1, 2 to be operated. Accordingly, it is here and preferably provided that the cloud server system 8 receives status information relating to the building drinking water network 1 to be operated , 2 is generated. In a particularly preferred embodiment, the status information relates to the state of hygiene, the water consumption, the energy consumption or the like of the building drinking water network 1, 2 to be operated.

Schließlich darf noch darauf hingewiesen werden, dass das vorschlagsgemäße Verfahren nicht auf die Kommunikation zwischen dem Cloud-Serversystem 8 und den Armatursteuerungen 3b-7b beschränkt ist. Vielmehr kann es zusätzlich vorgesehen sein, dass das Cloud-Serversystem 8 mit anderen Systemen wie einem Heizungssystem, einem Klimaanlagensystem, einem Lüftungssystem o. dgl. kommuniziert, um das Hygienespülen weiter zu optimieren. Insbesondere für den Fall, dass das Heizungssystem eine Temperaturregelung für das zum Hygienespülen auszulassende Trinkwasser bereitstellt, ist eine entsprechende Abstimmung zwischen den Spülaktionen und der Temperatur des Trinkwassers, insbesondere also eine Abstimmung zwischen dem Cloud-Serversystem 8 und dem Heizungssystem, erforderlich.Finally, it should also be pointed out that the proposed method is not limited to the communication between the cloud server system 8 and the fitting controls 3b-7b. Rather, provision can also be made for the cloud server system 8 to communicate with other systems, such as a heating system, an air conditioning system, a ventilation system or the like, in order to further optimize hygienic flushing. In particular, if the heating system provides temperature control for the drinking water to be let out for hygiene rinsing, appropriate coordination between the rinsing actions and the temperature of the drinking water, in particular coordination between the cloud server system 8 and the heating system, is required.
