The invention further relates to a sensor arrangement for a building closure element and a building closure element with a sensor arrangement.

[0002] From the prior art, for example, the document DE 10 2018 112 956 A1 is known. This describes a method for mounting a component in an opening in a building wall, comprising the following steps: Providing the component; Fastening drives at least in the corner regions of the component, wherein the drives are configured to adjust the distance between the component and the opening in the building wall in two spatial directions; Arranging the component with the drives attached thereto in the opening in the building wall; Providing at least one position-determining device on the component; Triggering an alignment process of the component in the opening in the building wall; Carrying out the alignment process, in which the alignment of the component is carried out by changing the distances between the component and the opening in the building wall by means of the drives;Ending the alignment process when a desired alignment of the component in the opening in the building wall is achieved; and fixing the alignment of the component in the opening in the building wall. Further relevant methods are known from EP 3 805 505 A1, US 2008 / 271517, WO 2022 / 017838, and DE 10 2017 103020 A1.

[0003] It is an object of the invention to propose a method for operating a sensor arrangement of a building closure element, which has advantages over known methods, in particular particularly reliably detects and indicates errors during transport and / or assembly of the building closure element.

[0004] This is achieved according to the invention with a method for operating a sensor arrangement of a building closure element having the features of claim 1. It is provided that the sensor arrangement is an integral component of the building closure element and is operated at least temporarily during a transport and / or assembly process of the building closure element to detect the state variable, and that a state signal determined as a function of the detected state variable is output by the sensor arrangement at least once.

[0005] Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims.

[0006] The method serves to operate the sensor arrangement, which is a component of the building closure element. The building closure element can be a component of a building, but can of course also be separate from the building, at least until it is mounted on the building. The building has a building shell, for arrangement on or in which the building closure element is provided and designed. The building shell lies between an external environment of the building and an interior of the building, thus separating them from one another. The building shell is preferably designed as a wall of the building or as the roof of the building. The building closure element serves to at least temporarily close the building, in particular to at least temporarily close a recess formed in the building shell.The recess, which is at least temporarily closed by means of the building closure element, is either a wall opening or a roof opening.

[0007] The wall is designed in particular as the exterior wall or outer wall of the building. The roof, on the other hand, essentially consists of a roof structure and a roof covering. The roof structure has, for example, one or more rafters and one or more roof battens. The roof battens can be divided into counter battens and support battens, whereby the presence of counter battens is purely optional. The support battens are usually arranged at an angle, in particular perpendicular, to the rafters and attached to them. The counter battens, on the other hand, preferably run at an angle to the support battens, in particular perpendicular to them, and / or parallel or at least essentially parallel to the rafters.

[0008] The roof skin is arranged or attached to the outside of the roof structure, thus defining the roof structure's exterior. The term "roof skin" refers, in particular, to a roof covering or roof waterproofing. The roof covering comprises, for example, a plurality of roof tiles, roof stones, roof shingles, or the like. Towards the inside, i.e., toward the interior, the roof structure is preferably defined by an interior wall. For this purpose, the interior wall is arranged and / or attached to the roof structure on its side facing the interior. For example, the building closure element is connected to the interior wall via an interior lining.

[0009] The building closure element is preferably designed as a door or a window. The window can be a roof window or skylight, in particular a residential roof window or a roof window or a skylight, or alternatively a facade window. Alternatively, the building closure element can be a roller shutter or a shading device. The building closure element can be designed to close the recess in a translucent or opaque manner. If the building closure element is translucent, it has, in particular, glazing, which can be, for example, single glazing or multiple glazing, in particular double glazing or triple glazing.

[0010] The building closure element preferably has one or more frames. The frame or each of the frames has a plurality of frame members. The frame members are fastened to one another in such a way that they accommodate a region of the building closure element between them. The frame members therefore form a closed frame. The frame or the plurality of frame members are in particular designed such that they overlap and / or cover the recess in the building envelope. The frame members are preferably arranged and designed such that, together with the glazing, they completely close the recess, at least temporarily. For this purpose, the glazing is preferably carried by the frame. For example, it is enclosed by the plurality of frame members.

[0011] The building closure element can be permanently closed, i.e. designed to permanently close the recess. In this case, it has, for example, only a single frame which is rigidly connected to the building shell. However, it can also be provided that the building closure element can be opened and closed. In this case, it preferably has several frames, one of the frames being designed as a fixed frame and another as a sash frame. The sash frame is displaceable, in particular pivotable, with respect to the fixed frame. If the sash frame is present, the glazing is preferably attached to it and is only indirectly supported by the fixed frame via the sash frame. Accordingly, the glazing can be displaced or pivoted together with the sash frame with respect to the fixed frame.

[0012] The sensor arrangement of the building closure element has at least one state variable sensor. With the aid of the state variable sensor, the state variable of the building closure element is detected, in particular measured, at least temporarily. Provision can be made for the sensor arrangement to have only a single state variable sensor for detecting only a single state variable. However, provision can also be made for several different state variables to be detected by means of the state variable sensor, or for several state variable sensors to be present, by means of which several different state variables can be detected. More generally, the sensor arrangement has one or more state variable sensors, by means of which one or more state variables are detected or measured, at least temporarily.The state variable is understood to be a variable describing the building closure element or a variable describing a state of the building closure element. For example, the state variable sensor detects the state variable directly at the building closure element or in the immediate vicinity of the building closure element, for example, in the outdoor environment and / or in the interior.

[0013] The sensor arrangement is an integral component of the building closure element. This means that the sensor arrangement is already assigned to the building closure element during its manufacture. At the very least, the sensor arrangement is permanently attached to the building closure element, in particular to the frame or one of the frames. Thus, there is no merely temporary attachment of the sensor arrangement to the building closure element. The attachment can preferably be effected in such a way that the sensor arrangement cannot be separated from the building closure element, or at least cannot be separated without damage. For example, the sensor arrangement is arranged in a recess formed in the building closure element, such that it is not or only partially visible from the outside environment.Preferably, the recess is closed after the arrangement of the sensor arrangement in it, so that the sensor arrangement does not influence the visual impression of the building closure element.

[0014] After the building closure element has been manufactured, a transport and / or assembly process takes place. The transport process particularly comprises transporting the building closure element from a factory in which the building closure element is manufactured to an assembly location for the building closure element, where the building closure element is mounted, i.e. the assembly process takes place. The assembly location preferably corresponds to a location of the building. However, it can also be provided that the transport process begins later, for example at an intermediary to whom the building closure element is transported from the factory. In this case, the transport process comprises transporting the building closure element from the intermediary to the assembly location.

[0015] The assembly process of the building closure element is carried out at the installation site. The assembly process is understood to mean, in particular, a process from the removal of packaging that at least partially encloses the building closure element to the final placement of the building closure element in the recess of the building envelope. The assembly process begins with the removal of the packaging, for example, with the start of the removal of the packaging or immediately after the complete removal of the packaging. It ends as soon as the building closure element is positioned and secured in the recess of the building envelope.

[0016] For example, the end of the assembly process of the sensor assembly is communicated by an input. For this purpose, the sensor assembly has a corresponding input device. The input device can be a physical device, for example a button, a switch, or the like. However, it can also be present on a mobile device that is connected to the sensor assembly via a data transmission link. In this case, it is provided, for example, that the fitter carrying out the assembly of the building closure element records an identifier of the building closure element with the mobile device, for example by manually entering a code or by scanning a QR code located on the building closure element.The mobile device subsequently transmits the end of the assembly process to the sensor assembly, for example, directly via a data transmission connection between the mobile device and the sensor assembly or indirectly via a central processing unit that is separate from the mobile device and the sensor assembly. The central processing unit is in data transmission connection with both the mobile device and the building closure element. In any case, the data transmission connection is preferably wireless.

[0017] The sensor arrangement is intended and designed to detect or measure the state variable at least temporarily during the transport and / or assembly process. The state signal is determined as a function of the detected state variable and output by the sensor arrangement. The output can, for example, be directly via a display device of the building closure element or the sensor arrangement. However, it can also be provided that the state signal is transmitted to the mobile device and / or the central computer device. The output is fundamentally independent of the transport and / or assembly process. It can therefore be provided that the output takes place during the transport and / or assembly process. Alternatively, it can only be carried out after the transport and / or assembly process.Due to its dependence on the detected state variable, the status signal directly describes the status of the building closure element during the transport and / or assembly process. Accordingly, a statement about the status is already possible at this point in time and not only after completion of the assembly process. In particular, the output of the status signal allows reliable quality control during the transport and / or assembly process. It can be provided that the status signal is only output immediately at the end of the transport and / or assembly process. However, it can also be provided that the status signal is output multiple times, for example periodically. In particular, it is provided that the status signal is output at least once during the transport process and / or assembly process, but preferably multiple times, in particular periodically.Thus, based on the status signal, a distinction can be made between the transport process and the assembly process and, for example, conclusions can be drawn as to whether damage to the building closure element occurred during the transport process and thus already before the assembly process or only during the assembly process and thus after the transport process.

[0018] For example, the sensor arrangement is used to monitor compliance with applicable regulations regarding the connection of the building closure element to the building. In particular, it can be provided to measure the temperature on the building closure element, in particular on its inside, and to compare the measured temperature with an inside and / or outside temperature. The inside and / or outside temperature can also be measured or received via the data transmission connection. If a difference between the inside temperature and the measured temperature is too large or greater than a first limit value and / or a difference between the measured temperature and the outside temperature is too small or smaller than a second limit value, this indicates incorrect installation of the building closure element, in particular incorrect connection of the building closure element to the building.Accordingly, the output status signal is provided with an error message.

[0019] A further development of the invention provides that the sensor arrangement has a power source which is electrically connected via a switch to the state variable sensor and / or to an evaluation electronics electrically connected to the state variable sensor, wherein the switch, after manufacture of the building closure element, is initially in a deactivation setting in which the state variable sensor and / or the evaluation electronics are electrically separated from the power source, and is brought into an activation setting before the transport and / or assembly process in which the state variable sensor and / or the evaluation electronics are supplied with electrical current from the power source.

[0020] The building closure element is manufactured before the transport and / or assembly process. For example, after its manufacture, the building closure element is initially stored in the factory, in particular in the same factory in which it is manufactured. Only after this storage does the transport and / or assembly process take place. To avoid unnecessary power consumption of the sensor arrangement, it is therefore initially deactivated using the switch, namely by setting the switch to the deactivation setting. Only when an impending transport and / or assembly process is about to begin, for example immediately before or at the start of the process, is the switch set to the activation setting, in which the sensor arrangement is activated.

[0021] In addition to the state variable sensor, the sensor assembly includes the power source and the evaluation electronics. The power source is electrically connected to the state variable sensor and / or the evaluation electronics via the switch. The power source is preferably a battery or the like, whereby the sensor assembly can only be operated for a limited period of time using the electrical energy stored in the battery. The evaluation electronics serves to evaluate a measured value supplied by the state variable sensor. The determination of the state signal and the output of the state signal are preferably performed by the evaluation electronics.

[0022] The switch is, for example, a mechanical or electronic switch. Preferably, when leaving the factory, it is switched from the deactivation setting to the activation setting by the building's locking element, so that the sensor array is subsequently activated and operates at least temporarily to detect the state variable, and the state signal determined depending on the detected state variable is output at least once. This approach ensures targeted quality control.

[0023] A further development of the invention provides that an acceleration sensor is used as the state variable sensor, by means of which the state variable present as acceleration is measured. If the measured acceleration exceeds an acceleration threshold value during the transport and / or assembly process, the output status signal is provided with an error message. The acceleration sensor measures the acceleration of the building closure element in at least one direction, preferably in several mutually perpendicular directions, particularly preferably in three mutually perpendicular directions.

[0024] If the acceleration exceeds the acceleration threshold, damage to the building closure element is assumed, and the corresponding error message is output as part of the status signal. The acceleration threshold is preferably selected such that mechanical damage to the building closure element reliably does not occur as long as the acceleration acting on the building closure element is lower than the acceleration threshold. This enables reliable detection of damage to the building closure element during the transport and / or assembly process.

[0025] A further development of the invention provides that a position sensor is used as the state variable sensor, by means of which the state variable present as the actual position is measured, wherein if the measured actual position deviates from a target position stored in the sensor arrangement during the transport and / or assembly process, the output status signal is provided with an error message. The sensor arrangement is therefore used to monitor whether the building closure element is installed at the intended installation location. For this purpose, the geodetic actual position of the building closure element is determined or measured using the position sensor. The position sensor is, for example, The actual position is then compared with the target position stored in the sensor arrangement. If the actual position deviates from the target position, the error message is output as part of the status signal.Using this approach, it is possible to reliably determine whether the building closure element has reached its correct installation location and has been installed there. For example, the target position is transmitted to the sensor array before the transport and / or installation process and stored there, particularly from the central computer and / or the mobile device.

[0026] A further development of the invention provides that a rotation angle sensor is used as the state variable sensor, by means of which the state variable present as the actual rotation angle is measured, wherein if the measured actual angle of rotation deviates from a target angle of rotation stored in the sensor arrangement during the transport and / or assembly process, the output status signal is provided with an error message, or if a rotation angle limit value is exceeded by a total angle of rotation aggregated from the actual angle of rotation during the transport and / or assembly process, the output status signal is provided with an error message.

[0027] The angle of rotation sensor can be used to measure the angle of rotation of the building closure element, in particular, a geodetic orientation of the building closure element in at least one spatial direction. For example, the acceleration sensor is used as an angle of rotation sensor, and the actual angle of rotation is determined from the acceleration acting on the building closure element.

[0028] Various evaluations can be carried out using the actual angle of rotation. For example, it can be checked whether the assembly process was completed correctly by comparing the actual angle of rotation with the stored target angle of rotation. The target angle of rotation is preferably transmitted to the sensor arrangement in analogy to the target position and stored there. If the actual angle of rotation deviates from the target angle of rotation, the error message is output as part of the status signal. The actual angle of rotation describes, for example, the inclination of the building closure element at which it should be present after the assembly process has been completed. In particular, the target angle of rotation corresponds to the pitch of the roof on or in which the building closure element is installed.

[0029] Alternatively or additionally, the actual angle of rotation is aggregated to form the total angle of rotation. This means that the actual angle of rotation is measured multiple times, and the total angle of rotation is calculated from the multiple actual angles. The total angle of rotation describes the angle of rotation by which the building closure element was rotated during the transport and / or assembly process, in particular during the entire transport and / or assembly process. If this total angle of rotation exceeds the angle of rotation limit, it is concluded that the building closure element is damaged, and the error message is output as part of the status signal. The two procedures described enable particularly reliable quality control of the transport and / or assembly process of the building closure element.

[0030] A further development of the invention provides that a noise sensor is used as the state variable sensor, by means of which the state variable present as a noise level is measured, wherein if a noise level threshold is exceeded by the measured noise level during the transport and / or assembly process, the output status signal is provided with an error message. Such a procedure enables, for example, effective protection of the installer from excessive noise during the assembly process. The noise level threshold is preferably selected such that, at a noise level corresponding to the noise level threshold, no health impairment of the installer can occur or it can be assumed that the installer will not be distracted from the assembly work. This reliably prevents errors during assembly.

[0031] A further development of the invention provides that the noise sensor is designed as a microphone and is used for the speech recognition of a voice command, wherein an actuator of the building closure element is controlled during the transport and / or assembly process depending on the voice command. Such a procedure facilitates the assembly process by the installer. The actuator is used, for example, to open and close the building closure element, i.e., to move the sash frame relative to the frame. Alternatively, the actuator is used to move a shading device of the building closure element. When a specific, defined voice command is received, which is recognized by the microphone, the actuator is controlled accordingly. In particular, several different voice commands are stored in the sensor arrangement, which are assigned to different operating modes of the actuator.

[0032] A further development of the invention provides that at least one of the following sensors is used as the state variable sensor: brightness sensor, temperature sensor, heat flow sensor, dust sensor, humidity sensor, VOC sensor, CO2 sensor, O3 sensor, flow velocity sensor, and lidar sensor. At least one of the aforementioned sensors can be used in addition to or alternatively to the sensors already mentioned above, i.e., the acceleration sensor, the position sensor, the angle of rotation sensor, the noise sensor, and / or the microphone.

[0033] The sensor arrangement can in principle have any number of state variable sensors and record any number of state variables. This means that exactly one or more of the aforementioned sensors can be present as part of the sensor arrangement. The brightness sensor is used to record brightness, the temperature sensor is used to record temperature, the heat flow sensor is used to record heat flow, the dust sensor is used to record dust density, the humidity sensor is used to record humidity, the VOC sensor is used to record the concentration of volatile organic compounds (VOCs), the CO2 sensor is used to record CO2 concentration, the O3 sensor is used to record ozone concentration, the flow velocity sensor is used to record the flow velocity of air in the vicinity of the building closure element, and the lidar sensor is used to record the distance to a solid object in the vicinity of the building closure element.

[0034] At least one of the variables mentioned serves to detect conditions that could lead to damage to the building closure element, so that the status signal reflects the condition of the building closure element. As already explained, this method enables reliable quality control, since the environmental conditions of the building closure element are also assessed, which inevitably influence its condition and are therefore considered state variables.

[0035] A further development of the invention provides that a sound emitter arranged on a first side of the building closure element emits sound with a specific sound intensity, and a state variable sensor configured as a noise sensor determines a noise level of the sound on a second side of the building closure element facing away from the first side and uses this as a state variable. For example, the sound emitter is arranged on a side of the building closure element facing the outside environment, and the noise sensor is arranged on a side of the building closure element facing the interior, or vice versa.

[0036] The sound emitter emits sound at a specific, precisely defined intensity. On the second side of the building closure element, the emitted sound is measured using the noise sensor and recorded as the noise level. For example, the sound can be emitted at a specific frequency or across multiple frequencies. It can also be configured to change the frequency of the sound while the sound is being emitted, particularly continuously or with defined jumps. The noise level is used as a state variable, and the state signal is determined based on it. This allows the installation process to be monitored with regard to sound insulation, particularly the connection of the building closure element to the building.

[0037] Preferably, it is ensured that the sound is emitted and the noise level is recorded when the building closure element is in a defined state, in particular when the building closure element is closed and a defined degree of shading is present (if a shading device is present). The described procedure enables a reliable estimation of the condition of the building closure element.

[0038] A further development of the invention provides that the start and / or end of the transport and / or assembly process is detected based on the detected state variable, with a time of start and / or a time of end being output as part of the status signal. The detected state variable is evaluated to this extent and evaluated for the start or end. This can be done particularly effectively, for example, based on the acceleration and / or the actual position of the building closure element. If an acceleration and / or a change in the actual position occurs over a certain period of time, the execution of the transport and / or assembly process is detected. In this context, the acceleration of the building closure element is preferably understood to mean an acceleration that deviates from normal gravity.The transport and / or assembly process is deemed to have taken place if the measured acceleration, corrected for the acceleration due to gravity, is different from zero or exceeds a threshold value.

[0039] The time at which the transport and / or assembly process begins is preferably set to the time at which the acceleration, in particular the acceleration different from zero or exceeding the threshold value, and / or the change in the actual position began. Conversely, the end of the transport and / or assembly process can be detected by determining the time at which the acceleration is zero or falls below the threshold value and / or the actual position no longer shows any change. The time of start and the time of end are output as part of the status signal. This also enables reliable quality control, namely by determining the duration of the transport and / or assembly process. Inadmissibly long storage of the building closure element can be detected in this way.

[0040] A further development of the invention provides that the completion of a work step in a sequence of several work steps, in particular transport and / or assembly steps, is detected based on the detected state variable, and the detected work step and / or a work step following it in the sequence is output as part of the status signal. The work steps include, for example, removing packaging from the building closure element, arranging the building closure element in the recess of the building shell, fastening the building closure element to the building shell, and commissioning the building closure element. The completion of the respective work step can be detected based on the state variable, preferably by detecting characteristic patterns that occur during the respective work step.The detected work step or the subsequent work step is then output as part of the status signal. This provides the installer with assistance or specific instructions on how to install the building closure element.

[0041] A further development of the invention provides that the output of the status signal comprises displaying the status signal for a fitter of the building closure element, in particular by means of the sensor arrangement and / or the mobile device and / or the central computing device, and / or transmitting the status signal to a central computing device. The status signal is output, for example, directly using the sensor arrangement. The sensor arrangement preferably has a corresponding display device for this purpose. Additionally or alternatively, the status signal can be transmitted to the mobile device or the central computing device and displayed there. The status signal can be transmitted to the mobile device either directly via a data transmission connection between the sensor arrangement and the mobile device or merely indirectly via the central computing device.For this purpose, the central computer communicates with both the sensor array and the mobile device. This enables local quality control by the installer themselves or central quality control by the manufacturer of the building closure element.

[0042] A further development of the invention provides that the state variable is recorded multiple times and recorded in a state variable curve. The state variable curve describes the course of the state variable over time. Preferably, the state variable is stored in the state variable curve together with a time stamp describing the time at which the state variable was recorded. Thus, the state variable is preferably recorded multiple times, particularly periodically, during the transport and / or assembly process, and its course is recorded in the state variable curve.

[0043] The state variable profile can, for example, be stored in the sensor arrangement. In this case, the state signal is preferably output only once, in particular at the end of the transport and / or assembly process or after the transport and / or assembly process. This significantly reduces the energy required to output the state signal. Alternatively, the state variable can also be transmitted immediately after it has been detected, for example, to the mobile device and / or the central computing device. In this case, the state variable profile is available in the mobile device or the central computing device. This has the advantage that the current state of the building closure element is always known to the mobile device or the central computing device.

[0044] A further development of the invention provides that the detected state variable is stored multiple times in a data memory of the sensor arrangement to compile the state variable profile, with the state variable profile being output as part of the state signal. Such a procedure has already been mentioned. It enables particularly energy-efficient operation of the sensor arrangement, since the state signal is output comparatively rarely, in particular only once. Thus, the output of the state variable profile preferably occurs less frequently than the detection of the state variable.

[0045] A further development of the invention provides that the state variable curve is compiled from the state variable transmitted with the state signal. This means that the state signal is output multiple times by the sensor arrangement, in particular each time the state variable is detected. The state variable curve is then compiled from the output state signal or the state variable transmitted with it by an external device, for example, the central processing unit or the mobile device. This enables a temporally resolved observation of the transport and / or assembly process by these devices.

[0046] A further development of the invention provides that the sensor arrangement is permanently deactivated after the end of the transport and / or assembly process, or that the sensor arrangement continues to be operated at least temporarily to detect the state variable after the end of the transport and / or assembly process, and that the state signal determined as a function of the detected state variable is periodically output by the sensor arrangement. According to a first variant of the described method, the sensor arrangement is no longer required after the end of the transport and / or assembly process and is deactivated accordingly, for example by disconnecting the power source from the state variable sensor or the evaluation electronics, preferably permanently and irreversibly. In such a procedure, the sensor arrangement serves solely to evaluate the transport and / or assembly process.

[0047] According to a second variant, the sensor arrangement is also used after the transport and / or assembly process, in particular to monitor the operation of the building closure element. Preferably, the sensor arrangement is used for error detection, wherein the detected state variable is evaluated to detect an error or defect in the building closure element. If such an error or defect occurs, an error message is output with the status signal. This also ensures reliable operation of the building closure element. For example, the error message is transmitted with the status signal to the mobile device and / or the central computer. These initiate appropriate measures. For example, a service technician is dispatched to the building closure element.

[0048] A further development of the invention provides that in a training operating mode of a transport and / or assembly monitoring device, a transport and / or assembly quality is recorded after the transport and / or assembly process and is correlated with the state variable and / or the state variable curve by means of the transport and / or assembly monitoring device and / or in a monitoring operating mode of the transport and / or assembly monitoring device, the transport and / or assembly quality is determined from the state variable and / or the state variable curve by means of the transport and / or assembly monitoring device.

[0049] The training mode is used to teach the transport and / or assembly monitoring device. This can be the mobile device described above or the central computer. At the end of the transport and / or assembly process or after it, the transport and / or assembly quality is recorded. This is done in particular by manual input. For example, the fitter and / or an inspector checking the transport and / or assembly quality enters the transport and / or assembly quality manually. This can be done directly on the sensor arrangement, which has a corresponding input device for this purpose. However, the transport and / or assembly quality is preferably entered on the transport and / or assembly monitoring device or the mobile device.For example, both an identifier of the building closure element and the transport and / or assembly quality are queried and subsequently transmitted to the transport and / or assembly monitoring device. Querying the identifier can involve manually entering the identifier or, for example, scanning a marking attached to the building closure element, in particular a QR code.

[0050] The transport and / or assembly monitoring device correlates the transmitted transport and / or assembly quality with the state variable or the state variable curve. The correlation is preferably carried out by machine learning and / or by performing a regression analysis or regression. Within the scope of the regression, the transport and / or assembly quality serves as the regression parameter and the state variable or the state variable curve as the regressor. A linear regression, for example, is used as a regression. Within the scope of the correlation, the transport and / or assembly quality is thus related to the state variable or the state variable curve, for example by means of regression. This results in a correlation during the training mode, which can subsequently be used to draw conclusions about the transport and / or assembly quality from the state variable or the state variable curve.Regression is preferably performed using a neural network. Deep learning can generally be used to achieve particularly meaningful results.

[0051] In addition to or as an alternative to the training mode, the transport and / or assembly monitoring device can be operated in the monitoring mode. Preferably, the transport and / or assembly monitoring device is first trained in the training mode and then operated in the monitoring mode. In the monitoring mode, the transport and / or assembly monitoring device determines the transport and / or assembly quality from the state variable or the state variable curve. This makes it possible to directly estimate the transport and / or assembly quality based on the state variable or its curve, without the need for laboriously determining and manually entering the value.

[0052] For example, in monitoring mode, the transport and / or assembly quality is determined and compared with a limit value. If the transport and / or assembly quality falls below this limit value, an error is displayed or a signal indicating the error is output. For example, the building closure element is then inspected and any transport and / or assembly errors or damage found are rectified. In addition, the state variable or the state variable curve as well as a manually entered transport and / or assembly quality are preferably used to improve the correlation. If, on the other hand, the transport and / or assembly quality is greater than the limit value, either no signal is output or a signal is output that indicates that the building closure element is in perfect condition.The procedure described enables particularly simple and reliable quality monitoring of the transport and / or assembly process.

[0053] A further development of the invention provides that the transport and / or assembly monitoring device is a component of the building closure element or of a central computer located at a distance from the building closure element. This has already been mentioned. The use of the central computer as a transport and / or assembly monitoring device makes it particularly advantageous to carry out the training mode using the state variable or the state variable profile of a plurality of sensor arrangements or building closure elements, thus providing a very large database.

[0054] A further development of the invention provides that the sensor arrangement is a component of a plurality of sensor arrangements of a plurality of building closure elements, wherein, in the training mode, the correlation between the transport and / or assembly quality, on the one hand, and the state variable and / or the state variable profile of the sensor arrangements, on the other hand, is temporarily stored in the transport and / or assembly monitoring device. In addition to the sensor arrangement, there is thus at least one further sensor arrangement or preferably several further sensor arrangements, which together form the plurality of sensor arrangements. The sensor arrangements are assigned to a plurality of building closure elements.

[0055] The sensor arrangements transmit the respective state variable and / or the respective state variable profile, for example, as a component of the state signal or as a state signal, to the transport and / or assembly monitoring device. The transport and / or assembly monitoring device determines the correlation between the transport and / or assembly quality, on the one hand, and the state variable or the state variable profile, on the other, and temporarily stores this correlation. In this process, the transport and / or assembly quality and the state variable or the state variable profile of the plurality of sensor arrangements are combined, so that ultimately there are fewer correlations than sensor arrangements, in particular a single correlation exists for all sensor arrangements.

[0056] The monitoring device preferably distinguishes between different types of sensor arrays or building closure elements. Thus, a separate correlation is determined and temporarily stored for each type of sensor array and / or each type of building closure element. This enables particularly precise quality control.

[0057] A further development of the invention provides that in the monitoring mode, the state variable and / or the state variable curve are transmitted to the transport and / or assembly monitoring device, which determines the transport and / or assembly quality from them using the correlation and transmits it to the sensor device, or that the correlation is transmitted from the transport and / or assembly monitoring device to the sensor arrangement and the transport and / or assembly monitoring device determines the transport and / or assembly quality based on the correlation using the state variable and / or the state variable curve.

[0058] Two different approaches are available for evaluating the transport and / or assembly quality in monitoring mode. First, the transport and / or assembly quality can be evaluated by the transport and / or assembly monitoring device. For this purpose, the state variable or the state variable curve is transmitted to it. The transport and / or assembly monitoring device determines the transport and / or assembly quality based on the state variable or the state variable curve and transmits this information back to the sensor device.

[0059] Alternatively, the transport and / or assembly monitoring device transmits the correlation to the sensor array. In this case, the transport and / or assembly quality is determined by the sensor array itself, namely again using the state variable or the state variable curve. In the former case, it is always ensured that the current correlation is used. In the latter case, no data transmission connection is required between the transport and / or assembly monitoring device and the sensor array. Preferably, the correlation is transmitted to the sensor array before the transport and / or assembly process and temporarily stored there.

[0060] The invention further relates to a sensor arrangement for a building closure element, in particular for carrying out the method according to the explanations in the context of this description, wherein the sensor arrangement is an integral component of the building closure element and has at least one state variable sensor for detecting a state variable of the building closure element. It is provided that the sensor arrangement is an integral component of the building closure element and is intended and configured to be operated at least temporarily during a transport and / or assembly process of the building closure element to detect the state variable and to output a state signal determined as a function of the detected state variable at least once.

[0064] The features and feature combinations described in the description, in particular the features and feature combinations described in the following description of the figures and / or shown in the figures, can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments are also considered to be encompassed by the invention that are not explicitly shown or explained in the description and / or the figures, but which follow from or can be derived from the explained embodiments.

[0065] The invention will be explained in more detail below with reference to the initial examples shown in the drawing, without any limitation of the invention. Figure 1 a schematic sectional view of a building with a building envelope and a building closure element.

[0066] The Figure 1 shows a schematic sectional view of a building 1, which has a building shell 2 and a building closure element 3. In the exemplary embodiment shown here, the building shell 2 is in the form of a roof, in particular a pitched roof. A recess 4 is formed in the building shell 2, which extends completely through the building shell 2 and in this respect connects an external environment 5 of the building 1 with an internal space 6 of the building 1, in particular in terms of flow technology and / or optics or lighting. The recess 4 is closed with the building closure element 3, in particular in terms of flow technology. In the exemplary embodiment shown here, the building closure element 3 is in the form of a roof window, which has glazing 7, so that there is still an optical connection between the external environment 5 and the internal space 6 through the recess 4.

[0067] The building closure element 3 has a sensor arrangement 8 which has at least one state variable sensor for detecting a state variable of the building closure element 3. The sensor arrangement 8 is an integral component of the building closure element 3. In the exemplary embodiment shown here, it is integrated, for example, into a frame 9 of the building closure element 3. The sensor arrangement 8 is operated at least temporarily during a transport and / or assembly process of the building closure element 3 to detect the state variable. In addition, a state signal determined as a function of the detected state variable is output by the sensor arrangement 8 at least once. The state signal can be output during the transport and / or assembly process or only after it. In this respect, the state signal is output, for example, independently of the transport and / or assembly process.

[0068] Also shown is a transport and / or assembly monitoring device 10, which in the exemplary embodiment illustrated here is designed as a central computing device arranged at a distance from the building closure element 3. The transport and / or assembly monitoring device 10 is at least temporarily in data transmission connection with the sensor arrangement 8. In a training operating mode of the transport and / or assembly monitoring device 10, it is provided that the state variable or a state variable curve is transmitted as part of the state signal from the sensor arrangement 8 to the transport and / or assembly monitoring device 10. In addition, a transport and / or assembly quality is determined and also made available to the transport and / or assembly monitoring device 10. The transport and / or assembly quality is determined, for example, by manual input, for example on a mobile device.

[0069] The transport and / or assembly monitoring device 10 determines a correlation between the transport and / or assembly quality and the state variable or the state variable profile. This correlation is temporarily stored. Preferably, the transport and / or assembly quality and the state variable or the state variable profile are transmitted to the transport and / or assembly monitoring device 10 not only from the one building closure element 3, but from a plurality of building closure elements 3.

[0070] If sufficient transport and / or assembly quality, as well as state variables or state variable curves, were recorded during the training mode and taken into account when determining the correlation, the system switches from the training mode to a monitoring mode. In this mode, the correlation is used to infer the transport and / or assembly quality for this sensor arrangement 8 or the corresponding building closure element 3 from a state variable or a state variable curve transmitted by the sensor arrangement 8.

[0071] The described procedure enables particularly simple and reliable quality control of a transport and / or assembly process for the building closure element 3. In particular, it is only necessary to manually record the transport and / or assembly quality for the building closure element 3 during the training mode. After completion of the training mode and during the monitoring mode, the transport and / or assembly quality is determined using the transport and / or assembly monitoring device 10, and if the transport and / or assembly quality falls below a threshold value, an appropriate measure is initiated. For example, a service technician is dispatched to inspect the building closure element 3. LIST OF REFERENCE SYMBOLS
