Definitions

  • the invention relates to a method for controlling a building's drinking water network with sanitary fittings by means of an internet-based cloud server system according to claim 1 and to a hygiene flushing system according to claim 16.
  • a well-known method for operating a building drinking 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 located in the building concerned, 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, especially in the case of complex building drinking water networks. This also means that an expansion of the building technology is always accompanied by a corresponding control technology challenge.
  • the building's drinking water network works independently to the extent that information from outside, for example information from building drinking water networks that are to be operated in parallel, is not used in the implementation of the hygienic flushing.
  • information deficit there is a considerable potential for optimization with regard to the quality of hygienic washing.
  • 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 effort in terms of control technology.
  • the building's drinking water network be operated using an internet-based cloud server system.
  • 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 provides the computing power that is required by the building's drinking water network.
  • the cloud server system has access to information from external data sources via the Internet, on the basis of which the hygiene flushing can be optimized according to various criteria.
  • An example of this is weather information that provides information on whether the formation of germs in the building's drinking water network is supported by the weather, which should result in increased hygiene flushing.
  • the building's drinking water network is equipped with sanitary fittings, each of which has an electrically controllable water outlet valve and a mobile radio-compatible fitting control. So it is the sanitary fittings possible to communicate over a cellular connection. This already has the structural advantage that an expansion or reduction of the building's drinking water network is unproblematic in terms of control technology.
  • the cloud server system generates communication objects in the form of hygiene flushing instructions according to a hygiene flushing strategy.
  • a hygiene flushing strategy For the generation of the hygiene flushing instructions according to the hygiene flushing strategy, all of the above-mentioned information is also available from external data sources, so that the generation of the hygiene flushing instructions can be optimized and adapted to the current information.
  • the hygiene flushing instructions generated in this way are then transmitted to the respective valve control via a mobile radio connection between a public mobile radio access point and the valve control.
  • a cellular connection is provided between a public cellular access point and the valve control.
  • the cellular access point is a gateway between the cellular network and the Internet.
  • the mobile radio connection a decentralized approach has been chosen according to the proposal, in which each sanitary fitting, taken by itself, establishes a mobile radio connection to the relevant public mobile radio access point.
  • the term “public” only means that the cellular radio access point is also accessible to cellular radio users who do not belong to the building's drinking water network.
  • the hygiene flushing instructions generated and transmitted by the cloud server system can be implemented by the respective fitting control by activating the respective water outlet valve.
  • the proposed method is not limited to the process step of implementing the hygiene flushing instructions on the part of the valve controls. Initially, it is only about the feasibility of the hygienic flushing instructions on the part of the valve controls. Provision is only preferably made that the proposed method includes the method step of implementing the hygiene flushing instructions generated and transmitted by the cloud server system by controlling the respective water outlet valve.
  • 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 radio connection for each individual sanitary fitting.
  • the last-mentioned, decentralized control aspect ensures, as already indicated above, flexibility in the design of the building's drinking water network without any control-related restrictions being expected. This goes back to the consideration that each sanitary fitting organizes the communication to the cellular radio access point independently. Retrofitting an existing building drinking water network is also unproblematic.
  • the first-mentioned, central control aspect enables use for all sanitary fittings that are operated by the cloud server system due to the internet-based cloud server system, so that an optimization of the hygienic flushing results in a form that was previously only possible with great effort.
  • the central control aspect of the proposed method results in the additional advantages of a uniform software management for all sanitary fittings, a uniform fault diagnosis for all sanitary fittings, and a uniform emergency function for all sanitary fittings, such as the emergency shutdown of all sanitary fittings.
  • the preferred refinements 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 separated building drinking water networks. Then, in a preferred variant of claim 2, operating information from a building's drinking water network can be used for operating another building's drinking water network.
  • the further preferred refinements according to claims 4 and 5 relate to details of the hygiene flushing instructions.
  • Claim 4 clarifies in particular that the hygiene flushing instructions can be a direct instruction in the sense of a switching command, but also an indirect instruction in the sense of a time specification for the hygiene flushing operation in question.
  • the likewise preferred refinements according to claims 6 and 7 relate to the possibility of bidirectional data transmission between the cloud server system and the fitting controls, in that the fitting controls each generate fitting communication objects and transmit them to the cloud server system via the respective cellular connection.
  • the fitting communication objects represent status information and / or fitting sensor information and / or user inputs.
  • Other types of fitting communication objects are conceivable.
  • a feedback can be established from the faucet controls to the cloud server system, which ranges from a simple confirmation of the implementation of a hygiene flushing instruction to a technical feedback.
  • interconnected data processing between the cloud server system and the sanitary fittings is completely dispensed with. This means that data processing of the communication objects that go beyond measures for data transport is dispensed with. This corresponds to a consistent implementation of the above-mentioned central tax aspect of the proposed procedure.
  • a preferred option for the transmission of user communication objects is the subject matter of claim 9. It is proposed here that an internet-based user terminal is provided for this, which communicates with the cloud server system via an internet connection. This enables the user to access the cloud server system regardless of their location. This is associated with a particularly high level of convenience.
  • the further preferred refinements according to claims 10 to 13 relate to the generation of a hygiene flush plan from hygiene flush actions by means of the cloud server system (claim 10).
  • the basis for this is the hygiene flush 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.
  • 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 hygiene status, 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.
  • a further increase in user comfort can be achieved according to claim 15 in that status information relating to the building's drinking water network to be operated is generated by the cloud server system and output here, preferably via the above user terminal. This means that the user is informed of the current status of the building's drinking water network, regardless of where he is.
  • the hygiene control system has the above cloud server system which is set up to carry out the proposed method is essential.
  • the above building drinking water network as such is not part of the hygiene control system.
  • the proposed method is used to operate at least one building drinking water network, here operating a first building drinking water network 1 and operating a second building drinking water network 2.
  • the proposed method can be provided for operating a plurality of building drinking water networks 1, 2. All statements relating to the two illustrated building drinking water networks 1, 2 apply accordingly to all other building drinking water networks 1, 2 that may be provided.

  • the proposed method is primarily explained with reference to the first building drinking water network 1, which is not to be understood as limiting.
  • the sanitary fittings 3-7 can be any sanitary fitting that has a water outlet valve for discharging drinking water. These include, for example, wash basin fittings, shower facilities, toilets, urinals, or the like. Correspondingly, they do not include all types of shut-off valves that do not allow water to escape.
  • Fig. 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 below.
  • the sanitary fittings 3-7 each have an electrically controllable water outlet valve 3a-7a and a fitting control 3b-7b capable of mobile radio.
  • Electrically controllable means in the present case that the sanitary fittings 3-7 designed as water outlet points are set up to be electrically opened and closed by a corresponding activation by the fitting control 3b-7b in order to allow or block the discharge of drinking water.
  • Internet-based in connection with the cloud server system 8 means in the present case that the cloud server system 8 is set up to communicate via an internet connection.
  • communication objects in the form of hygiene flushing instructions 9 according to a hygiene flushing strategy 10 are generated by the cloud server system 8 (method step A in FIG Fig. 2 ).
  • the hygiene flushing strategy 10 is dependent on various influencing factors, as will be explained below.
  • 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 Fig. 2 ).
  • 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 Fig. 2 ).

It is preferably the case that operating information is generated by the cloud server system 8 during the operation of a first building drinking water network 1, which information is used by the cloud server system 8 for operating a second building drinking water network 2. In the simplest case, this means that the cloud server system 8 uses the hygiene flush strategy 10 of the first building drinking water network as the basis for operating the second building drinking water network 2. As mentioned above, this shows the advantage of the central tax approach of the proposed solution.
  • the building's drinking water network 1, 2 to be operated is assigned to a building 12, 13 or a building complex.

For example, it can be provided that all sanitary fittings 3-7 of a logical group are flushed in uniform flushing cycles. This can be provided in addition to the hygiene rinsing, which is triggered locally, for example by locally high ambient temperatures.
  • Fig. 1 shows that the cloud server system 8 communicates with the cellular radio access point 11 via an internet connection 14, while the cellular radio access point 11 communicates with the fitting controls 3b-7b as above addressed via the cellular connections 3c-7c.
  • the above-mentioned combination of the central tax aspect with the decentralized tax aspect is interesting.

In particular, it is preferably such that the at least one hygiene flushing parameter is a hygiene flushing time relating to the hygiene flushing action, a hygiene flushing duration relating to the hygiene flushing action, or the like. is. It must be taken into account that the hygiene flush time can also describe the immediate activation 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.
