Description

The invention relates to a method for monitoring a water supply network of a building and a system for monitoring a water supply network of a building.

A building is usually equipped with at least one water pipe network, which is connectable via a connection to a water source, such as a water supply network, in particular a remote water supply network, or a water well. Such a water network is (only) through the connection, in particular a so-called house connection, fed with water and distributes the water through pipes inside and / or outside the building. For example, a plurality of water extraction devices can be provided inside and / or outside the building, where water can be taken from the water supply network.

The problem with a water supply network of a building is that damage to at least part of the water supply network can occur. Exemplary types of damage are pipe breaks and micro-leaks. The cause of a pipe break can be manifold. For example, the cause may be frost, a material or manufacturing fault from a water pipe, a surge, severe corrosion, material fatigue, and / or careless construction work (eg, with an unknown location of the pipes). A micro-leakage can precede a pipe break.

In principle, methods and systems for monitoring a water supply network are known from the prior art. For example, it is known to shut off the inflow upon detection of a pipe burst. Often, however, a significant amount of water has leaked, which can lead to significant further damage if no further immediate action is taken.

Therefore, the object of the invention is to provide a method and a system for monitoring a water supply network of a building, which enables improved monitoring of the water supply network and, in particular, at least reduces the damage due to damage to the water supply network.

• – Bereitstellen von mindestens einem gemessenen Wasserleitungsparameter des Wasserleitungsnetzes,
• – Detektieren von mindestens einer Beschädigung des Wasserleitungsnetzes abhängig von dem bereitgestellten Wasserleitungsparameter,
• – Übertragen einer ersten Alarmmeldung von einer zentralen Steuerungsvorrichtung an einen ersten Server bei Detektion einer Beschädigung des Wasserleitungsnetzes,
• – Übertragen einer weiteren Alarmmeldung von dem ersten Server an einen zweiten Server nach Empfang der ersten Alarmmeldung,
• – wobei nach Empfang der ersten Alarmmeldung von dem ersten Server ein Aussenden einer ersten Alarmmitteilung an eine erste Kommunikationseinheit über einen ersten Kommunikationskanal bewirkt wird, und
• – wobei nach Empfang der weiteren Alarmmeldung von dem zweiten Server ein Aussenden einer weiteren Alarmmitteilung an eine weitere Kommunikationseinheit über einen weiteren Kommunikationskanal bewirkt wird.

This object is achieved by a method according to claim 1. The method provides monitoring of a water pipe network of at least one building. The method comprises:

• Providing at least one measured water pipe parameter of the water pipe network,
• Detecting at least one damage to the water supply network depending on the provided water pipe parameter,
• Transferring a first alarm message from a central control device to a first server upon detection of damage to the water supply network,
• Transferring a further alarm message from the first server to a second server after receiving the first alarm message,
• - When, after receiving the first alarm message from the first server sending a first alarm message to a first communication unit is effected via a first communication channel, and
• - Wherein, after receiving the further alarm message from the second server sending a further alarm message to a further communication unit via a further communication channel is effected.

By, in contrast to the prior art, a connection of the monitoring of a water supply network of a building to a central control device of the building, it is possible to at least reduce the consequential damage associated with a damage to the water network. In particular, preferably at least two different communication units can inform about the occurrence of damage by means of a first server and a second server via preferably different communication channels. A user, in particular occupants of the building, can be reliably informed in a timely manner.

According to the method of the invention, in particular, the condition of a water supply network of a building is monitored. The building can be a single-family house, an apartment building, an office building, a factory building, etc. A building may comprise one or more separate water mains. A water pipe network is characterized in that it is fed from an external source of water via a connection with water and in particular distributes this water via pipelines of the water network within and / or outside the building to at least one water tapping point.

At least one waterline network parameter of the waterline network is provided. Preferably, at least one sensor may be provided for measuring the at least one water supply network parameter. The measurement can be carried out in particular adjacent to the house connection. One Water line network parameters of the water supply network is presently a measurable parameter from which a state parameter of the water network, in particular damage to the water network, can be derived.

Depending on the (almost) continuously measured water supply network parameter, damage to the water supply network can be detected. In the present case, damage is understood as meaning, in particular, actual damage and / or potential damage to the water supply network. In the event of potential damage, the cause of a correspondingly conspicuous water line parameter value may be actual damage to the water supply network or other, for example, a non-fully (fully) intercepted water extraction device, a leaky seal of a water extraction device, etc.

If a damage is detected, this is transmitted in the form of a first alarm message from a central control device, in particular a central control device of a home automation system, the building via a communication network, such as the Internet, to a particular remotely located first server. The first server is in particular a central administrative unit. The first server can be used, for example, to configure the home automation system.

The first server is in particular configured to evaluate the first alarm message. Furthermore, after receiving the first alarm message, the first server initiates at least two actions. On the one hand, the first server in particular directly effects the sending of an alarm message to a first communication unit, such as a mobile device. The first communication unit may be assigned to a user of the building. For example, the communication unit can visually and / or audibly display the received alarm message. In this case, the first alarm message can be transmitted via a first communication channel, such as a first mobile radio network. In addition, the first server causes the transmission of another alarm message to a second server, in particular remote from the first server and the central control device. For example, the second server can not make direct contact with the central control device.

The second server is set up in particular to evaluate the further alarm message. The second server can be set up to send out another alarm message to a further communication unit via a further communication channel. The further communication unit may differ in particular from the first communication unit. The further communication unit may be assigned to the same user as the first communication unit. Alternatively, the communication unit may be assigned to another user of the building, such as another occupant of the building. The communication unit may be another mobile device or another device, such as a landline device. Preferably, the further communication unit can be contacted by comparison with the first communication channel via another communication channel, such as another mobile radio network or a landline network. As a result, the probability is significantly increased that at least one user of the building is actually informed of the occurrence of damage in a timely manner, even if there is a fault of a communication channel and / or a communication unit. Measures can be taken in a timely manner to at least reduce the damage due to damage to the water supply network.

Furthermore, it may preferably be provided that the second server, after receiving the further alarm message, immediately initiates measures to reduce the further damage. For example, the second server may include sending another message to another communication unit from a resource such as a craftsman and / or fire department. The at least one resource can then drive to the building and preferably repair the damage.

It should be noted that a message, in particular an alarm message, in the present case may comprise a text message, a telephone message, etc. Furthermore, a message or message may be a push message or a push message.

In a first embodiment of the method according to the invention, upon detection of damage to the water supply network, an interruption of the water flow into the water supply network can be effected. For example, a valve arranged in an inflow of the water supply network can be controlled in such a way that upon detection of a damage, at least when a pipe burst in the water supply network is detected, the valve seals off the inflow. In particular, after detection of a pipe burst by a detection device, such as a control module of a monitoring device, the control module can cause an interruption of the water flow into the water pipe network. Preferably, the monitoring device comprising the valve can be integrated in the water supply network to a pipe of the house connection. This allows the by damage caused by the pipe burst is at least reduced.

As already described, the at least one water pipe parameter can be any parameter from which at least one damage to the water pipe network can be derived or determined. According to a preferred embodiment, the at least one water pipe parameter may be a measured water inflow into the water pipe network and / or a measured water pressure at a predeterminable location in the water pipe network. In particular, it has been recognized that damage can be derived from the water inflow quantity, that is to say the volume flow, into the water supply network. The water inflow rate indicates how much volume of water per unit of time is transported or fed through the cross section of an inflow pipe into the water supply network. In the event of a pipe break, it can be assumed that the water inflow quantity flowing in this phase is greater than the water inflow amount during normal operation of the water supply network. It has also been recognized that, alternatively or additionally, the water pressure can be detected in particular in an inflow pipe in order to detect damage to the water pipe network. Thus, the pressure drop at a pipe break is usually greater than the pressure drop in a normal operation of the water network.

Alternatively or additionally, it can be provided that at least one further measured parameter selected from the group water temperature of the water in the water network, pH of the water in the water network, water hardness of the water in the water network and / or ambient moisture provided in a predeterminable environment to the water network becomes. In one embodiment, it can be provided that at least one status information is transmitted from the central control device to the first server depending on the at least one further water parameter provided. The first server may cause a first status message to be sent to the first communication unit depending on the received status information. Alternatively, the first server may cause a transmission of another status message depending on the received status information to the second server. For example, the user can be informed of the water quality status messages.

The ambient humidity may be, for example, the moisture at a particular low-lying point of the building, such as a basement. As a result, in particular a water ingress can be detected early in the building. This can be reported from the central controller to the first server, from the first server to the second server and then to the at least one communication unit according to the previous statements.

Advantageously, furthermore, alternatively or additionally, at least the water temperature can be detected. This information can be transmitted from the first server to the second server. It has been recognized that the measured water temperature is an indication of an increased risk of flooding. In particular, a water temperature below a certain threshold temperature may imply that snowmelt has begun. A corresponding warning message can be transmitted to at least one of the communication units by at least one server. The user may then take appropriate action if necessary. Furthermore, the information may be used to alert other resources and / or occupants of other buildings.

In addition, properties of the water, such as water hardness and / or pH of the water, can be measured by at least one suitable sensor and identified to a user via the previously described route. The user may take appropriate measures, such as additional filtering means, etc., based on the water quality values, to change the corresponding water parameter.

In addition, according to another embodiment, detecting at least one damage to the waterline network depending on the provided waterline parameter may include comparing the provided waterline parameter to at least a first threshold and detecting a first type of waterline network corruption when the first threshold is exceeded. The first type of damage may be, for example, a pipe break. For example, based on tests, a first limit value for a permissible inflow quantity or a permissible pressure drop can be predetermined. By detecting the instantaneous inflow quantity and / or the instantaneous water pressure almost continuously and comparing it with the corresponding first limit value, a first type of damage in the form of a pipe burst can be detected in a timely manner.

Alternatively, or additionally, detecting at least one damage to the waterline network depending on the provided waterline parameter may include comparing the provided waterline parameter to at least a second threshold and detecting a second type of waterline network corruption when the second one is exceeded Include limit. The second type of damage may in particular be a micro-leakage. A micro-leakage may in particular precede a previously described pipe break. In the case of micro-leakage, a small amount of water escapes slowly. The problem with micro-leakage is that it usually goes unnoticed in prior art systems. One way in which a micro-leakage can be detected in this case involves the detection of the amount of water flow into the water supply network during a certain period of time. The period of time is characterized in particular by the fact that during this period of time (as a rule) there is no removal of water from the water supply network. The beginning of the period may be predetermined and / or determined or at least adjusted depending on at least one home automation sensor. If, for example, it is detected by the control device that water is not being withdrawn from the water supply network at the moment and thus can not be expected for the specific period of time, a checking step, in particular for detecting a micro-leakage, can be carried out as follows:
The inflow of water into the water supply network can be interrupted for a certain period of time, for example in the minute range (between 1 and 10 minutes). In particular, the valve described above can be closed. After the time has elapsed, the valve can be opened and the water flow rate can be measured. If the measured water inflow exceeds the second limit, there may be micro-leakage. If a water inflow amount is detected which is below the second limit value, in particular (almost) zero, no damage is present.

Preferably, in the manner described above, upon detection of a potential damage, a warning message can first be transmitted by at least one server to at least one communication unit as an alarm message. The reason for this is that in addition to a micro-leakage, other causes, such as a not fully locked faucet or the like can be considered. In particular, after other causes have been resolved and / or a certain amount of time has expired, preferably the above checking step may be performed again. If an exceeding of the second limit value continues to be detected during the renewed check, alarm messages can be transmitted to the communication units in accordance with the above statements.

This check or the like can in particular be carried out regularly, for example at least once a day. It is understood that when detecting a water withdrawal during the checking step, for example, due to an operation of a toilet flush, the valve opened in a timely manner and the review can be repeated at a later date.

In one embodiment, the first threshold and / or the second threshold may be a fixed threshold. For example, this can be set in the factory or in the installation of a monitoring device in the water network. For example, the fixing in the installation can be made depending on the type of water supply network (number of removal devices, length of the water supply network, average diameter of the pipes, average water pressure, etc.).

In a particularly preferred embodiment, at least one threshold of the first threshold or the second threshold may be a dynamically alterable threshold. A dynamically changeable limit value is characterized in that the limit value can be changed in particular depending on a current or estimated operating state of the water supply network and during operation of the water supply network. For example, the central control device may be configured to automatically adjust the at least one limit value, in particular the first limit value. By optimizing a limit value, on the one hand, the probability of detection of (actual) damage can be increased and, on the other hand, the number of false alarms can be reduced.

According to a further embodiment, the home automation system may comprise at least one home automation sensor and / or at least one actuator. The central control device may communicate with the home automation sensor and / or the actuator. For example, a wired and / or wireless communication connection between the at least one home automation sensor and / or the at least one actuator and the central control device may be provided. In particular, the central control device may obtain status data about a device of the building from the home automation sensor. In particular, the device may be a water extraction device of the water pipeline network. For example, the water extraction device, a faucet for filling a water basin, such as a swimming pool, whirlpool, bathtub, or for connecting an irrigation arrangement z. B. for a garden, etc. The actuator of a home automation system is in particular configured to control at least one device. Exemplary and non-exhaustive controllable devices may be lamps, radiators, blinds, irrigation devices, a faucet, etc. The actuator may, for example, cause an opening or closing of a locking device (eg valve), activation of a lamp, a method of a blind, etc.

Furthermore, according to an embodiment, the at least one dynamically changeable limit value can be changed dynamically by the central control device as a function of a home automation parameter acquired by a home automation sensor of a home automation system and / or dependent on a specifiable state information. In particular, the instantaneous water consumption in the water supply network can be determined by the central control device, for example, by evaluating the sensor data from at least one home automation sensor assigned to a water extraction device. If the control device determines, for example, that at least one water extraction device is open, in particular a plurality of water extraction devices is open, the control device can bring about an increase of the dynamic first limit value. If the state of a water extraction device changes from open to closed, the first limit value can be correspondingly reduced. In addition, the central control device can alternatively or additionally evaluate a specifiable status information, such as absence information of the user / s of the building. For example, during an absence of a user, the first threshold may be reduced (and then increased again).

Moreover, it has been recognized that, according to a preferred embodiment, a condition of a person in the building can be monitored at least as a function of the measured water pipe parameter. In particular, the time duration in which no water is withdrawn from the water supply network can be detected by a central control device. A time limit can be specified. The measured time duration can be compared with the time limit value. The time limit value can be set in such a way that, in the case of normal operation of the water supply network, before the time limit expires, water removal is carried out in particular by the person to be monitored with a high degree of probability (eg> 95%). Exceeding the time limit value can be evaluated by the central control device as an indication that a critical (health) state of the person is present. The reliability of the condition monitoring of the person can be improved if the central control device additionally takes into account data from at least one home automation sensor and / or predefinable status information, such as absence or presence information of the person. For example, the home automation system may comprise an electronic, in particular intelligent door closing mechanism. The door closing mechanism may include means for, for example, automatically detecting the presence and absence of persons in the building. The door closing mechanism can be controlled via a mobile device, for example, opened and closed. In such a door closing mechanism also the breaking of the front door can be omitted. Preferably, in cooperation with at least one other home automation sensor, such as a window sensor, a motion and smoke detector, a shutter control and / or an integrated camera, the condition of a person in the building can be reliably monitored. The central control device can, as previously stated, the first server and additionally via the first server to inform the second server accordingly. The first and / or the second sensor can / cause suitable measures.

If the method described above is not yet implemented in a home automation system or the required hardware modules are not yet installed in the water line network, according to a preferred embodiment in an installation step, a monitoring device with at least one sensor is arranged to detect at least one water pipe parameter of the water pipe network in the Water supply network to be installed. In particular, a mechanical integration into the water supply network, in particular at the connection of the water supply network, as well as an electrical installation and a communication connection to the control device, in particular communication technology integration in the home automation system, are performed.

After detection of a functional readiness of the monitoring device, a first test alarm message can be transmitted to the first server by the central control device. Another trial alert message may be transmitted from the first server to the second server upon receipt of the first trial alert message. Upon receipt of the first trial alarm message, the first server may cause a first trial alert message to be sent to the first communication unit via the first communication channel. After receiving the further sample alarm message, the second server can send out a further sample alarm message to the further communication unit via the further communication channel.

As a result, the operational readiness of all components in particular can be tested.

Another aspect is a system for monitoring a water pipe network of a building according to the independent claim. The system is in particular a monitoring system. The system comprises at least one monitoring device which can be integrated into the water pipeline network and has at least one sensor configured to detect at least one water line parameter of the water pipeline network. The system comprises at least one detection device configured to detect at least one damage to the water supply network depending on the provided water line parameter. The system comprises a central control device, in particular of a home automation system. The central control device is set up to transmit a first alarm message to a first server upon detection of damage to the water supply network. The first server is set up to transmit a further alarm message to a second server upon receipt of the first alarm message. After receiving the first alarm message, the first server is set up to effect a transmission of a first alarm message to a first communication unit via a first communication channel. After receiving the further alarm message, the second server is set up to effect the sending of a further alarm message to a further communication unit via a further communication channel.

Preferably, the method described above can be carried out by means of the system described above.

The functioning of the system 100 according to 1 and the preferred embodiment of a monitoring device according to the invention 208 according to 2 is subsequently using the 3 described in more detail. The 3 shows a schematic flow diagram of an embodiment of a method according to the present invention. In particular shows 3 a message diagram between the home automation system 326 ( 126 ) or the central control device 112 a home automation system, a first central management unit 316 ( 116 ) or a first central server 316 ( 116 ) and a second central administrative unit 318 ( 118 ) or a second central server 318 ( 118 ).

If not yet a monitoring device 208 in the water supply network to be monitored 114 is installed, in a first step 340 first the monitoring device 208 be installed. An installation particularly comprises a mechanical and electrical installation of the monitoring device 208 as well as a communication technology integration into the home automation system 326 , For example, the user may previously (eg, by completing a contract) the second server 318 have caused a shipment of a monitoring device 208 as well as the order of at least one craftsman to effect. Also at this point user data, such as address data of the first and second communication unit 122 . 124 , Identification of the home automation system and / or the central control device 112 , etc. in at least one database of at least one server 316 . 318 be deposited

In step 340 First, a mechanical installation of the monitoring device 208 respectively. The line entrance 236.1 especially with the pipeline of the house connection 206 and the line output 236.2 with a pipeline of the water supply network 204 mechanical coupled. Subsequently, the electrical connection of the monitoring device 208 respectively. After the electrical connection, the monitoring device 208 be charged with water. If this is for example from the control module 228 can be detected, preferably by the control module 228 the operational readiness of the monitoring device 208 be checked by a stored routine.

For example, in parallel or after a positive check of the functional readiness can preferably be an automatic integration into the home automation system 326 respectively. In a registration process, the monitoring device 208 in the control device 112 be registered, so that the monitoring device 208 in the home automation system 326 is involved.

After the monitoring device 208 is ready for operation and integrated, this information can be the central control device 112 be transmitted. Upon receipt and in particular triggered by this information, the central control device 112 preferably generate a first sample alarm message automatically and to the first central server 316 submit (step 341 ). It is understood that a manual activation of a trial alarm may also be possible. The first server 116 is set up, in one step 342 evaluate the first trial alarm message and in particular identify it as a trial alarm message.

After identification, the first server sends 316 present a first sample alarm message (step 343 ) to the mobile device 122 about receiving a trial alarm. This can be done via a first communication channel 117 respectively. This can be the first server 316 in particular by means of an address database and the sender information of the received sample alarm message, the address of the mobile device 122 identify and send the message. The mobile device 122 may be configured to display the message of the first server via a display.

Furthermore, the first server sends 316 another trial alarm message to the second server 318 about receiving a first trial alarm message from the home automation system 326 , The message comprises in particular an identifier of the home automation system 326 and the information that a trial alarm from the home automation system 326 has been triggered.

The second server then sends 318 a further alarm message in particular to the further communication unit 124 via another communication channel 115 , For example, a message can be telephoned to the communication unit 124 or the user of the communication unit 124 be transmitted. In particular, the message may include the information that a trial alarm was successfully received by the second server 318 was received. The monitoring device 208 became successful in the monitored water supply network 204 Installed.

As already described, the sensors detect 209.1 to 209.6 the monitoring device 208 preferably continuously different parameters, such as the flow rate of the water, the temperature of the water, the pH of the water, the pressure in the water pipe of the water network, the humidity of the Environment, such as the moisture of a soil, the monitoring device, etc. These sensor data and / or data derived therefrom, such as the flow rate, etc., may be from the central control device 112 (eg regularly) as status information to the first server 316 be transmitted (step 347 ).

This data can be stored in a database of the server 316 stored, evaluated and in particular for information purposes to the mobile device 122 of the home automation system 126 be transferred (step 348 ). For example, the user can be informed about the current and / or historical water consumption, the current and / or historical water temperature, the current and / or historical pH value of the water, etc. In particular, time profiles of the various parameters can be transmitted and transmitted by the mobile device 122 are displayed.

In addition, preferably at least a portion of the from the first server 316 received and / or evaluated data representing the water network 204 or the environment, to the second server 318 be transferred (step 349 ). The data can be from the second server 318 be evaluated. In particular, from the data (and preferably corresponding data from other home automation systems) can be evaluated as to whether there is a hazardous situation of the monitoring water network, for example, due to a low, in particular below a predetermined temperature limit temperature, and / or a certain temperature change. From the water temperature can be derived, for example, whether to be expected with an increased amount of melt water. Suitable, in particular increased precautionary measures can be taken, since, for example, basement flooding can occur. It is understood that a corresponding evaluation of the first server 316 can be carried out.

Subsequently, the case is considered that a damage of the monitored water network 204 from the monitoring device 208 is detected (step 350 ). For example, in step 350 a first type of damage, in particular a so-called pipe break, detected. A pipe break is characterized in that a significant and unusual amount of water from the water network 204 exit. In particular, in this case, the flow rate per unit of time detected by a flow rate sensor may exceed a first limit value. For example, the control module 228 Check that the detected (instantaneous) flow rate exceeds the first limit.

It goes without saying that, additionally or alternatively, the sensor data from at least one further sensor, such as a pressure sensor, can be used to detect a pipe break. For example, a pipe break can be derived from a pressure drop exceeding a certain further first limit.

Preferably, the first threshold may be a dynamic threshold. In particular, a dynamic first limit value is to be understood as meaning a limit value which during the operation of the monitoring device 208 (automatically) changed, thus increased or reduced, can be. A change or adjustment of the dynamic first threshold may depend on the data received from one or more home automation sensors 120.2 be delivered, and / or of predeterminable state information, such as absence information, dynamically adapted by the control device.

For example, the central control device 112 perform an increase of the dynamic first limit upon detection of instantaneous (significant) water consumption. For example, one or more home automation sensors 120.2 the activation of an irrigation device, in particular of a garden irrigation system, the filling of a swimming pool, the filling of a whirlpool, the use of one, in particular a plurality of shower facilities, and / or the like, to the control device 112 Report. This can be done by the control device 112 evaluated and depending on the evaluation lead to an adjusted first limit.

On the other hand, for example, due to absence information or at times of low water consumption, such as at night, the dynamic first threshold may be from the central control device 112 be reduced. The corresponding data can be the central control device 112 due to the known configuration and / or detected instantaneous sensor data, such as opening a shut-off valve of an irrigation device or the like, get or know.

Represents the control module 228 a pipe break according to the previous versions firmly controls the control module 228 the shut-off module 230 and causes a barrier to the flow of water. No more water gets into the water mains 204 fed. The damage associated with a pipe breakage can at least be reduced.

Furthermore, an alarm message from the central control device 112 to the first server 316 be transferred (step 351 ). In particular, the alarm message may include a specification of the alarm, such as the information that a pipe break has been detected. For example, the control device 112 from the control module 228 been notified about the detection of a pipe break.

Similar to step 342 may be the first server 316 the received alarm message in step 352 evaluate. The first server 116 is in particular set up to identify the received alarm message as an alarm message and the affected home automation system 326 or the user of the home automation system 326 to identify from the alarm message.

After identification, the first server sends 316 a (push) alarm message (step 353 ) to the mobile device 122 about receiving an alarm. As previously described, the first server 116 in particular by means of an address database and the sender information of the received alarm message, the address of the mobile device 122 determine and effect the transmission of the first alarm message.

Furthermore, the first server sends 316 Another alarm message to the second server 318 about receiving the first alarm message from the identified home automation system 326 , The further alarm message comprises in particular an identifier of the home automation system 326 and the information that an alarm from the home automation system 326 has been triggered. In particular, the alarm message may include a specification of the alarm, such as the information that a pipe break has been detected.

The second server 316 In particular, an immediate contacting of the user, in particular via a telephone message (step 355 ), by means of the further communication unit 124 cause. Furthermore, measures can be taken to remedy the damage from the second server in a particularly automatic manner 318 be effected. For example, an automatic message may be transmitted to a resource such as a computing device associated with a craftsman. The message may include information about the address of the home automation system user and details of the damage. After remedying the damage, the water supply network can continue to operate as described above.

The following explains the case that the monitoring device 208 a second type of damage, in particular a so-called micro-leakage or a micro-leak, in the water supply network to be monitored 204 detected (step 356 ). A micro-leakage may in particular precede a previously described pipe break. In the case of micro-leakage, in particular, a small amount of water escapes slowly. The problem with micro-leakage is that it usually goes unnoticed in prior art systems.

The monitoring device 208 is set up, in a monitoring step 356 to detect a micro-leakage. In a first substep, the control module can be used to detect a micro-leakage 228 the shut-off module 230 trigger so that it remains locked for a predetermined period of time. The inflow of water into the water supply network 204 will be interrupted.

After expiry of the time period, the control module causes 228 an opening of the shut-off module 230 and the sensor 209.1 measures the inflow of water into the water supply network 204 , If no inflow of water is measurable, there is no damage to the water supply network 204 in front.

If, on the other hand, a water inflow quantity after opening exceeds a second limit value, then at least one potential damage is present in the form of a micro-leakage. After the detection of a potential damage, the central control device transmits 112 a corresponding first alarm message, in particular a warning message, to the first server 316 (Step 357 ). As already described, evaluates the first server 316 the first alarm message (see step 352 ) and causes a sending of another alarm message to the second server 318 (Step 359 ). Furthermore, the first server sends 316 in the present case, a first alarm message, in particular a warning message, to the first communication unit 122 , Similar to step 355 in the present case transmits the second server 318 a further alarm message, in particular a warning message, to the further communication unit 124 (Step 361 ).

Upon receipt of the first and / or second warning message, the user may, in step 362 check if the cause of the potential damage is, for example, a dripping faucet, etc. Possibly. may be a corresponding cause in the step 362 be eliminated. For example, a corresponding information to the first and / or second server 316 . 318 be communicated.

In the step 363 can according to the step 356 be checked again if there is damage in the form of a micro-leakage. It can thus be checked whether by the actions of the user the cause of the positive detection result in step 356 has been eliminated.

Detects in particular the control module 228 that the second limit is not exceeded, there is no damage. Preferably, this can according to the previous versions of at least one server 316 . 318 and at least one communication unit 122 . 124 be communicated.

Detects the control module 228 on the other hand, a (renewed) exceeding of the second limit value is now considered to be a real damage to the water supply network 204 went out. It is understood that in other variants, at least one further warning message can be sent first.

In step 363 can the control module 228 upon another detection of damage, closing the valve 230 cause. Further, in the steps 364 . 365 . 366 . 367 . 368 according to the comments on 351 to 355 be referred to at this point. The differences exist only in the types of damage pipe breakage and micro-leakage.

The following explains the case that the monitoring device 208 detected a flooding. In one step 369 can the humidity sensor 209.6 detect an ambient humidity and the corresponding data to the control module 228 transfer. From the detection of ambient humidity may be due to water ingress from the control module 228 getting closed. The control module 228 can send a message to the central control device 112 transfer. The control device 112 is set up, a first alarm message comprising information that a water leak has been detected, to the first server 316 transfer (step 370 ).

In the manner described above, the first server 316 after an evaluation (step 371 ) both the first communication unit 122 (Step 372 ) as well as the second server 318 (Step 373 ) inform accordingly. The second server 318 can an alarm message to the other communication unit 124 effect (step 374 ). Furthermore, the second server 318 to transmit an alarm message to at least one resource, such as fire brigade, craft business, etc.

It will be appreciated that the messages from the first server may be sent to any communication unit determinable by a user of the home automation system, such as a personal computer, a television set connected to the Internet, etc. In particular, the communication unit may only be for receiving messages be furnished.
