BUILDING SENSOR SYSTEM

Description

[0001] The present invention relates to a building sensor system according to the preamble of patent claim 1. Furthermore, the present invention relates to a method for integrative building management according to claim 12.

[0002] Such systems and methods are known in the state of the art and are used, for example, for situation-appropriate or adaptive control of building technology or the like.

[0003] For example, WO 2012 / 110046 A1 discloses a device and a method for monitoring and controlling traffic management at an airport, which comprises a plurality of data acquisition points distributed over the airport premises for collecting real-time data.

[0004] However, the known systems and methods have the disadvantage that the states of the room units monitored by the sensor system or by the method can only be determined with inaccurate or unreliable accuracy. Furthermore, the prior art methods and systems have the disadvantage that the states or events detected by the sensors are considered too isolated or insufficiently interconnected for building management purposes. Consequently, the potential of the systems and methods to optimize the control or management of a building is not fully exploited.

[0005] Based on this prior art, the object of the present invention is to propose a building sensor system and a method for integrative building management, which enables particularly precise recording of the states of individual room units and at the same time enables the most extensive, networked and thus meaningful evaluation of the recorded states of the room units in order to improve and make building management more effective.

[0006] This object is achieved by the building sensor system according to claim 1 and by the method according to claim 12. Advantageous developments of the invention are described in the subclaims.

[0007] The invention additionally leads to an accommodation facility, in particular a hotel, comprising a sensor system according to the invention and to the use of the method for the building management of an accommodation facility, in particular a hotel. The invention also leads to a stable facility, in particular a pet and / or farm animal stable, particularly preferably a horse stable, comprising a sensor system according to the invention and to the use of the method according to the invention for the building management of a stable facility, in particular a pet and / or farm animal stable, particularly preferably a horse stable. Furthermore, the invention also leads to a medical accommodation facility, in particular a hospital and / or retirement and / or nursing home, comprising a sensor system according to the invention and to the use of the method according to the invention for the building management of a medical accommodation facility.Furthermore, the invention provides a meeting and / or conference facility with a sensor system according to the invention, as well as the use of a method according to the invention for the building management of a day and / or conference facility. Finally, the invention also provides a workplace, in particular an office unit, with a plurality of workstations and a sensor system according to the invention, and the use of the method according to the invention for the building management of a workplace.

[0008] The building sensor system according to the invention for integrative building management accordingly comprises a plurality of sensor modules, each of which is assigned to a room unit and detects a state of the room unit, wherein the invention provides that a plurality of sensor modules comprises a sensor unit, in particular for detecting micro-movements, and each sensor unit is connected to a communication network via which the sensor units communicate with at least one central processing unit, which is in particular configured to identify micro-movements in the sensor signals of the sensor units, wherein the central processing unit is connected to at least one application unit, which is configured to send queries, in particular about micro-movements in the room units, to the central processing unit, to receive information, in particular about the micro-movements in the room units,to process the received information, in particular about the micro-movements in the room units, in an application-related and room-unit-related manner and to generate an application-specific output signal.

[0009] The basic idea of the invention is therefore to detect and identify states, in particular micro-movements, in the respective room units via the computing unit and the sensor units and to generate an application-related output signal from states, in particular the identified micro-movements, which in turn is used, picked up or reused in the building management of the building.This particularly advantageously achieves that, on the one hand, the recording and identification of states, in particular micro-movements, allows the states and state changes in the room units to be recorded with particular precision and high resolution. And, thanks to the networked, particularly cross-room-unit and simultaneously room-unit-specific further processing by the application unit, the recorded and identified states, in particular micro-movements, can be used very effectively and intelligently for building management, thus achieving very precise, effective building management. This achieves building management that significantly increases the benefits for the building's residents, users, or the like, while simultaneously achieving building management that can be carried out in a particularly energy-efficient and resource-saving manner.

[0010] The basic idea of the present invention furthermore consists in the fact that, on the one hand, the states, in particular micro-movements, which are measured or detected in the respective spatial units, form part of the basis for the processing by the application unit, but that the processing also takes into account application-related static or dynamic information, links this to the spatial units and the states there, in particular micro-movements, and, if necessary, establishes a larger context or an overall context that includes several spatial units, all spatial units, or the entire building. Thus, spatial-unit-related processing by the application unit can lead to an output signal that affects a single spatial unit, a plurality of spatial units, in particular a group of spatial units, or all spatial units or the entire building.In other words, depending on the application or subtask, the application unit is equally capable of generating an output signal that has a clear reference to one or more spatial units or of generating an output signal that is based on information regarding the spatial units but does not have a clear reference to the respective spatial units.

[0011] In principle, any structure can be considered a building within the meaning of the present invention. Even structural structures in public spaces that are not buildings in the classic sense can be considered buildings in the context of the present invention. The spatial units can each represent self-contained and separate rooms. Alternatively, however, the system can also be used for spatial units that divide a single room into several, in particular not structurally separate, sub-units, i.e. spatial units. For example, a single room can be considered a spatial unit. Alternatively, however, a spatial unit can also comprise an area of a larger room, for example an area of a hall, a section of an underground or parking garage, or a section of track in a train station. Several buildings can also be understood as a single spatial unit within the meaning of the present invention.

[0012] The sensor modules and the sensor units of the sensor modules will be discussed in more detail in the following disclosure. At this point, it should merely be explained that the sensor units are preferably configured to detect micro-movements in such a way that movements of a few millimeters, preferably movements of just one millimeter or less, can be detected and identified. For the connection between the sensor units and the computing unit, as well as for the connection between the computing unit and the application unit, and for any further connections between units of the system described in the following disclosure, all common and commonly used data connections, as well as their physical connection means and procedural connection or transmission protocols, are generally considered, unless otherwise specified.For example, wired or wireless connections can be used. According to the present invention, at least one application unit can be implemented as a separate physical unit. Alternatively, however, it can also be included in the central processing unit.

[0013] The identification of states, particularly micro-movements, can either be performed by the sensors themselves, or the task can be performed by the central processing unit. If micro-movements are to be not only detected but also identified by the sensor modules or sensor units, it can be advantageous for the sensor units, particularly the sensor modules, to have a sensor processing unit configured for this purpose. This can advantageously reduce the load on the central processing unit.

[0014] The central processing unit can be configured, for example, as a server. For this purpose, a server device physically assigned to the system can be provided. Alternatively, the server device can also be connected to the system via a network connection, which enables spatial decoupling between the central processing unit and the other system components. Furthermore, the central processing unit can also be implemented as a cloud computing service, without a local or decentralized physical system component permanently assigned to the system.

[0015] With regard to detecting the states of the spatial units, sensor units configured to detect micro-movements are preferably used. Alternatively or additionally, however, other sensor units can also be used. These include, among others, sensor units that comprise an imaging sensor or a camera sensor that images at least part of a spatial unit. Different spectral ranges of the electromagnetic spectrum can be of interest, and consequently the imaging or camera sensors can be configured for detection in the respective wavelength range. For example, infrared imaging sensors can be used. Additionally or alternatively, sensor units that enable 2.5-dimensional or 3-dimensional detection of the spatial unit can be used.Such scanners generate a height grid or point cloud from which changes in the spatial unit or its states can be accurately and reliably detected. In this configuration, the sensor units can be designed, for example, as stereo laser scanners.

[0016] Particularly preferably, a sensor unit can be configured both to detect spatial and / or optical properties of the spatial unit and to detect micro-movements within the spatial unit. This enables, for example, detection that allows determining where, in what position, and with what movement / acceleration a living being or a person is present or moving within the spatial unit. For this purpose, the previously described configurations of the sensor unit can be linked and combined with one another in a preferred manner.

[0017] The system according to the invention and also the method according to the invention are described below essentially with reference to sensor units that enable the detection of micro-movements or that emphasize the detection of micro-movements. However, the advantageous embodiments described below and their advantages can also be achieved or even improved upon using previously described configurations of the sensor units with different or possibly additional detection properties than those of sensor units that function as imaging units or as spatial scanners.

[0018] According to the invention, the sensor modules with a micro-motion sensor unit comprise at least one further functional unit in addition to the sensor unit. This particularly advantageously enables the sensor system, in particular the sensor modules assigned to the room units, to be integrated into existing infrastructure, in particular into existing building infrastructure or building management infrastructure. The functional units are other sensors, namely a motion sensor and a smoke detector, in particular sensors for detecting other properties or states. For example, the at least one further functional unit can be designed as a brightness sensor, fire extinguishing water sprinkler, or the like.A further advantage of the combination of sensor modules comprising a micro-movement sensor unit and a further functional unit is that it enables particularly advantageous retrofitting of the sensor modules. For example, a functional unit originally assigned to the room unit is replaced by a new functional unit which, in addition to the functional unit itself, also comprises the sensor unit, i.e. the micro-movement sensor unit, and thus no longer serves only as a functional unit, but also as a sensor module. In this context, it can also be particularly advantageous if the connection between the sensor unit and the central processing unit is wireless. This is because it enables retrofitting which, at least on a physical orAt the objective level, no retrofitting of connection infrastructure is required in the area in which the sensor module is to be arranged and, where appropriate, to replace or supplement a former functional unit. For example, if the micro-motion sensor unit is integrated into an otherwise non-networked, in particular battery-operated, smoke detector and a corresponding wireless connection is provided between the sensor unit and the central processing unit, the sensor module can be replaced or retrofitted simply, quickly, and cost-effectively, thus providing the special functionalities of the building sensor system according to the invention, without requiring any noticeable additional effort in the context of installing the sensor module.

[0019] In connection with the retrofitting of the sensor modules, it can also be particularly advantageous if existing infrastructure of the room units can be continued to be used. In this context, it is particularly advisable that the infrastructure already available for a specific functional unit is shared or taken up by a corresponding sensor module. Accordingly, a further, particularly advantageous embodiment of the sensor system provides that the sensor modules with a micro-motion sensor unit comprise a housing whose shape is adapted to the at least one additional functional unit. Accordingly, it can be achieved that the infrastructure of the respective functional unit, which is supplemented by the sensor unit, continues to be used or shared.In the relatively trivial example of a smoke detector already mentioned above, which is supplemented by the micro-motion sensor unit, this can, for example, lead to the fact that by adopting or replicating the corresponding housing of the functional unit, a mounting device, for example a mounting plate of the smoke detector fastened in the room unit, can be reused for the sensor module, whereby the subsequent installation or subsequent integration of the building sensor system according to the invention is particularly facilitated.

[0020] According to a further, particularly advantageous embodiment of the sensor system, the sensor unit can comprise a radar sensor, in particular an ultra-wide-band (UWB) sensor. Such sensors are particularly suitable as sensor units for detecting micro-movements for various reasons. On the one hand, such sensor units enable high spatial resolution. On the other hand, such sensor units emit very little power, so they can be used safely inside buildings. The sensor unit is particularly preferably designed as a combined transmitting and receiving unit (transceiver) and enables the emission or transmission of radiation in the radio frequency (RF) range as well as the reception of time-shifted reflex signals that are reflected and returned by objects in the room unit or objects of the room unit.

[0021] According to another particularly preferred embodiment of the system, the computing unit is configured to identify a micro-movement of a vital function of a living being in the spatial unit in the sensor signals. For this purpose, it can be provided that a frequency modulation, referred to as the micro-Doppler effect, is determined from the transmitted signals or the received signals of the sensor unit. For this purpose, for example, a Doppler map or a Doppler matrix can be created, which is then optionally transferred into a frequency domain using a Fourier transformation. A vital function of a living being in the spatial unit can be identified by detecting fundamental oscillations and harmonic overtones in the frequency domain.

[0022] According to a particularly preferred embodiment of the sensor system, the central processing unit can also be configured to identify a respiratory rate and / or a heartbeat rate in the sensor signals. Alternatively, this can already be enabled by the sensor unit. For this purpose, the sensor unit can comprise a sensor processing unit.

[0023] Both the identification of a living being's vital function and the special design of identifying a respiratory rate and / or a heartbeat rate enable the precise and reliable detection of the presence of a living being, particularly a human, in the respective spatial unit. This is of particular value for the proposed building sensor system, since building management is often geared towards the presence or absence of a living being, particularly a human, in the spatial unit. In other words, this means that building automation and integrated building management are particularly dependent on being able to determine with a high degree of certainty and reliability whether living beings, particularly humans, are present in the respective spatial unit.In this regard, breathing or respiratory rate, as well as pulse and its frequency, are particularly safe and reliable decision criteria or means of identification, making this vital function particularly suitable for reliably determining the presence or absence of a person, as well as entering or leaving the room unit. These vital functions are particularly advantageous to determine using the sensor module, in particular using the sensor unit, because in an even more extensive integration step of the building management system, a corresponding application unit generates an application-specific output signal not only on the mere presence or absence of a living being or person, but also depending on the physical condition of the person present, which in turn is determined via the corresponding vital functions using micro-movements. This output signal can then be processed in the building management system oris taken into account or further processed in the operation of the building.

[0024] As already mentioned above, instead of or in addition to the detection and identification of micro-movements, in particular vital functions, particularly preferably heartbeat and / or respiration, an optical imaging or detection and / or a spatial imaging or detection of the spatial unit using corresponding sensor units and a corresponding identification of states of the spatial unit can take place. This can then preferably relate to a movement profile of the spatial unit, in particular a movement profile of a human or living being as a state of the spatial unit. The identification of the human or living being can take place either via a micro-movement sensor unit or via optical and / or spatial detection using the at least one sensor unit.This further improves the evaluation or the ability to evaluate the information by the evaluation unit, since in many respects the localization information represents a valuable added value in addition to the mere detection or identification of a living being or a person, on the basis of which the application-related processing can be carried out by means of the application unit.

[0025] The following will provide more detail on the devices that are connected or can be connected to the application unit and that further process the application-specific output signal.

[0026] According to a first advantageous embodiment, it can be provided that the sensor system comprises a control unit for controlling at least one building function, in particular a room unit function, wherein the at least one application unit is connected to the control unit and the control unit is configured to control the building function, in particular the room unit function, depending on the output signal of the application unit.

[0027] Probably the simplest example in this context could be a control unit for air conditioning individual room units or groups of room units, for lighting individual room units or groups of room units and / or for sound reinforcement of individual room units or groups of room units. In this case, the proposed sensor system can be used to draw conclusions about changes in the room units and their current state, particularly with regard to the presence of living beings, particularly humans, based on the micro-movements detected and identified by the sensor unit and, if applicable, the computing unit.to connect an application-related and room-unit-related evaluation from the application unit to the application unit, which then concludes with the output of an output signal to the control unit.

[0028] In this case, for example, the application-related processing of the information received from the application unit can consist of comparing or linking information regarding the presence of people or living beings in room units with further application-related parameters. For example, for an application unit that is connected to a control unit for controlling the lighting in the building, the further application-related parameter can be a time of day, a time-of-day-dependent outside brightness, or the like. Depending on the further, application-related parameters, the application unit then generates and outputs the output signal, which the control unit can use to control the respective building functions, in particular room unit functions. For example, based on the output signal from the control unit, the lighting in individual room units can be switched on or off.Likewise, a control signal for air conditioning the room unit can be generated or output using the control unit.

[0029] It can also be provided that a higher-level context is created via the application unit, which is based on the generalization of micro-movements identified in a spatial unit. The generalization can, for example, relate to a spatial generalization with regard to a group of spatial units. For example, a temperature can be controlled in a group of spatial units, for example in the rooms of a hotel room, as soon as corresponding micro-movements are identified in a spatial unit. Likewise, a spatial generalization of the lighting can also take place in such a way that the application unit generates an output signal which, due to further processing by the control unit, does not exert any direct influence on the spatial unit or units in which the sensor units are arranged.For example, an output signal from the application unit could cause the control unit to dim or turn off the lighting in a hotel corridor if the sensor units assigned to the hotel rooms in the corridor do not detect the presence of a living being in the hotel rooms. This could occur regardless of whether the hotel corridor, as a room unit, has a sensor unit.

[0030] Alternatively or additionally, it can advantageously be provided that the sensor system comprises an organizational unit which is set up to plan room unit work, in particular maintenance and care work, wherein an application unit is connected to the organizational unit, and the organizational unit is set up to carry out the planning of building work depending on the output signal of the application unit.

[0031] The advantages of the organizational unit can be best described using the processes in a hotel building or an office building. In such buildings and the corresponding room units, a variety of building work arises, which, however, should preferably be carried out at times when the building users or guests are absent or will not be disturbed by the building work. Such work includes, among other things, cleaning work, maintenance and repair work. In such a context, the application reference under which the application unit creates the output signals taking into account the recorded and identified micro-movements can, for example, lie in a time interval since the last building work was carried out, in particular room unit work, or in the evaluation of the presence time of a person or living being in the respective room unit based on one or more limit values or the like.

[0032] In a preferred embodiment, the organizational unit comprises an output unit, which in turn preferably enables a visual output that outputs or displays the organization or planning of the building work. Screens, printers, or the like are suitable for this purpose. Mobile personal digital devices, such as smartphones or the like, can also serve as output units for the organizational units. Thus, for example, the cleaning of hotel rooms or office spaces in a corresponding building can be organized in a particularly advantageous manner, with the personnel performing the respective work receiving optimized instructions from the organizational unit for carrying out the activities or work.It can therefore be made possible, for example, for the application unit to generate an output signal which implies a cleaning plan, whereby both the sequence of the room units to be cleaned and the selection of the room units to be cleaned are generated in the room unit-related and application-related evaluation of the information from the sensor units and accordingly the organisational unit generates a visual plan, visual instructions or other outputs or instructions depending on the output signal of the application unit in order to specify or plan the optimised execution of the work for the staff.

[0033] Alternatively or additionally, it can advantageously be provided that the sensor system comprises a service unit configured to identify and / or plan services, in particular care and / or entertainment and / or fitness and / or wellness services, wherein an application unit is connected to the service unit, and the service unit is configured to carry out the identification and / or planning of service services depending on the output signal of the application unit. Furthermore, the service unit can be connected to at least one output unit, so that an identified service offer or a planned service is output or offered to a user, i.e., a person or living being located in a spatial unit.An input unit can be used to enable a user to confirm or reject a service offer or service, i.e. feedback can be transmitted to the service unit via a further connection with the service unit.

[0034] The functionality of the service unit largely corresponds to the functionality of the organizational unit, although the possibility of interaction with a user and any necessary output and / or input units are useful, since the service offering, in contrast to maintenance and care work, should be offered and provided in coordination with the user.

[0035] A further particularly advantageous embodiment provides that the sensor system is a security unit, for generating safety instructions and / or for coordinating or supporting rescue measures and / or for coordinating security or police operations, wherein at least one application unit is connected to the security unit and the security unit is configured to generate the safety instructions and / or to coordinate or support the rescue measures and / or security or police operations depending on the output signal of the application unit.

[0036] In this context, it can be provided, for example, that the room-unit-related and application-related parameters on which the processing of the application unit is based include the localization of room units with respect to the designated escape and rescue routes, the accessibility of room units with respect to specific rescue equipment, the arrangement and design of warning and indicator devices located in the room units, and the like. It can also be provided that the application-related and room-unit-related information and parameters that flow into the processing of the application unit originate from additional sensors apart from the designated sensor units for detecting micro-movement.In the present example, it can also be provided that the application- and / or room-unit-related parameters or information taken into account by the application unit originate from smoke detectors or other sensors located in the room units. Accordingly, the security unit can, on the one hand, trigger safety warnings, evacuation warnings, the display of escape routes, and the like based on the output signal from the output unit. On the other hand, the security unit can also provide emergency services, security guards, and / or police with information aimed at facilitating and optimizing their respective operations. For example, the emergency services can be informed in which room units and under what conditions living beings, especially people, are still present.In order to transmit such information and to issue notices or warnings, it may also be provided that the safety unit is provided with or connected to display and / or output means as well as to communication and / or transmission means.

[0037] A further, particularly advantageous embodiment of the sensor system also provides that the application unit comprises a pattern recognition means configured to recognize spatial and / or temporal patterns in the states and / or state changes of the at least one spatial unit as part of the application-related and spatial unit-related processing of the sensor signals, so that the application unit generates an output signal that is dependent on a pattern of a state and / or a state change of the at least one spatial unit. In this context, it should be mentioned that the pattern recognition provided by the pattern recognition means goes beyond the recognition or identification of people or living beings in a spatial unit, which in a broader sense also constitutes pattern recognition.The pattern recognition tools are designed to examine the corresponding sensor signals for the presence of patterns, especially for identified people or living beings. In doing so, movement patterns, activity patterns, or the like can be searched for and, if possible, identified. This can advantageously improve the application-related processing of information by the application unit by taking past patterns into account in addition to current information.

[0038] Another particularly advantageous embodiment of the sensor system also provides that the application unit comprises a prediction means configured to make a prediction about a future state of at least one spatial unit as part of the application-related and spatial unit-related processing of the sensor signals, so that the application unit generates an output signal that at least also depends on a future state of the spatial unit. The prediction can, on the one hand, directly or indirectly relate to the absence or presence of a living being, in particular a person, in the spatial unit and can be based on the sensor signals detected by the sensor unit and evaluated by the computing unit.On the other hand, the prediction can also relate to other application-specific or room-unit-related parameters and be made based on other room-unit-related or application-specific information, which is provided, for example, via other sensors or information systems. For example, it can be provided that if it is determined that a living being, in particular a person, leaves a room designed as a bedroom in the morning, the prediction or assumption is made that the person or living being will next enter or use a room designed as a toilet or bathroom. In this case, the prediction can be used by the respective application unit, for example, to establish a preliminary lighting state in order to activate ventilation or air conditioning, or the like.Accordingly, the output signal generated by the application unit can be generated taking the prediction into account.

[0039] Particularly advantageously, the prediction means can be linked or connected to a pattern recognition means, and the prediction is performed on the basis of patterns identified by the pattern recognition means. This advantageously enables the prediction to be based not only on a current state, but also to take past states and patterns recognized therein into account.

[0040] The object mentioned at the outset is achieved in the method according to the invention for integrative building management by means of a building sensor system, which comprises a plurality of sensor modules, each of which is assigned to a room unit and detects a state of the room unit, in that a plurality of sensor modules comprises a sensor unit, in particular for detecting micro-movements, wherein each sensor unit is connected to a communication network via which the sensor module communicates with at least one central processing unit, which in particular identifies micro-movements in the sensor signals of the sensor units, wherein the central processing unit is connected to at least one application unit and the application units send requests, in particular about micro-movements, in the room units to the central processing unit, receives information, in particular about the micro-movements, of the room units,and the received information, in particular about the micro-movements, is processed in an application-related and spatial unit-related manner and an application-specific output signal is generated.

[0041] The method according to the invention enables, on the one hand, changes in the spatial units, particularly regarding the presence or absence of people or living beings, to be recorded with high precision and high spatial resolution. At the same time, intelligent and resource-efficient building management for a large number of spatial units is achieved through application-related and spatial-unit-specific further processing or preparation of the precise information. As already described above, other sensor units can be used alternatively or additionally, for example, which optically or spatially detect the spatial unit and, if necessary, record the position, movement, and / or acceleration of living beings and possibly identify movement profiles.

[0042] With regard to the advantages, effects and implementation of the method, reference is also made to the preceding description of the system, since the method or implementation of the method realizes identical advantages, uses identical means and, to a large extent, the implementation of the method itself has already been carried out with reference to the disclosure of the system or can be deduced from it.

[0043] Particularly preferably, the computing unit can identify a micro-movement of a vital function of a living being in a spatial unit in the sensor signals. This can be done, for example, by examining signals and reflected response signals from a UWB transreceiver for the presence of micro-Doppler signals. The vital functions can be identified by transforming the evaluated signals into a frequency domain and examining them for fundamental frequencies and harmonics.

[0044] Particularly advantageously, the computing unit can identify a respiratory rate and / or a heartbeat rate in the sensor signals. This makes it particularly advantageous to identify the presence of a living being in the respective room unit with a high degree of certainty.

[0045] Alternatively, it may be provided that the identification of vital functions and / or heartbeat and / or respiration and / or position and / or movement and / or acceleration is carried out by a computing unit comprised by the sensor unit or the sensor module, thereby reducing the load or utilization of the central computing unit.

[0046] Furthermore, it can be particularly advantageously provided that an application unit is connected to a control unit for controlling at least one building function, in particular a room unit function, and the control unit controls the building function, in particular room unit functions, depending on the output signal of the application unit. It can preferably be provided that the application-related and room unit-specific evaluation by the application unit additionally takes into account information and parameters that are provided to the application unit either statically or variably, or that are provided to the application unit by other sensors or information systems.Controlling the room unit's function or the building's function can, for example, affect the control of lighting, air conditioning, or elevators, as well as the control of electronics or electrical equipment in the room unit. For example, the control unit can cause the lighting in the room unit to be switched off at a certain time of day, preferably in the evening or at night, after a certain time after a person has left a room unit, any electrical devices or electronics that are still in operation to be switched off or put into standby mode, and, if necessary, the temperature to be lowered and ventilation to be reduced.For this purpose, the application unit can, for example, link the information regarding the presence or absence of living beings, in particular people, in the respective room units with information about the time of day, information about the actual state of building functions or specifications for the target state of building functions and generate a corresponding output signal for the control unit.

[0047] It can also be particularly advantageous for the application unit to be connected to an organizational unit which is set up to plan room unit work, in particular maintenance and care work, and the organizational unit carries out the planning of building work depending on the output signal of the application unit.The output signal of the application unit can, for example, express in which room units of a building which are designed as bedrooms, living beings, in particular people, were present last night, who are no longer in the corresponding room unit at the current time and have preferably also already left adjacent room units, so that room unit work, such as cleaning work or housekeeping work, can already be carried out in the corresponding room unit designed as a bedroom and in the adjacent room units, whereas the output signal of the application unit for room units in which living beings, in particular people, are still present, generates an output signal which causes the organizational unit to suppress or postpone the corresponding room unit work, in particular to postpone cleaning work or housekeeping work.

[0048] Alternatively or additionally, it can advantageously be provided that the sensor system comprises a service unit configured to identify and / or plan services, in particular care and / or entertainment and / or fitness and / or wellness services, wherein an application unit is connected to the service unit, and the service unit identifies or plans services depending on the output signal of the application unit. Furthermore, the service unit can be connected to at least one output unit, so that an identified service offer or a planned service is issued or offered to a user, i.e., a person or living being located in a spatial unit.An input unit can be used to enable a user to confirm or reject a service offer or service, i.e. feedback can be transmitted to the service unit via a further connection with the service unit.

[0049] The functionality of the service unit largely corresponds to the functionality of the organizational unit, although the possibility of interaction with a user and any necessary output and / or input units are useful, since the service offering, in contrast to maintenance and care work, is intended to be offered and provided in coordination with the user.

[0050] It can also advantageously be provided that an application unit is connected to a security unit, which is configured to generate safety instructions and / or to coordinate or support rescue measures and / or to coordinate security or police operations, and the security unit generates the safety instructions and / or coordinates or supports the rescue measures and / or security or police operations depending on the output signal of the application unit. The application unit can therefore, for example, generate an output signal indicating whether a living being is present in a corresponding room unit, whether an elevated room temperature and, if applicable,whether smoke is developing, whether there are areas with an elevated temperature or smoke development on an escape route of the respective room unit, whether the respective room unit can be reached with special rescue equipment, such as a rescue ladder. Furthermore, in addition to the mere presence or absence of a living being in the room unit, the signals recorded by the sensor units and identified by the computing unit, in particular the identified vital functions with regard to the vital state of a person in the room unit, can be evaluated. According to the invention, an evacuation or rescue urgency level for the respective living being or for the respective room unit is defined in the output signal of the application unit as a function of this and the other parameters mentioned above.

[0051] Depending on the respective output signals, the security unit can then generate or initiate the output of safety instructions, and rescue measures, security guard or police operations, and similar deployments of emergency services can be supported or coordinated by providing corresponding information, for example in digital form or in the form of displays or outputs. For example, it can be provided that the security unit has a connection to the emergency services' communication tools and transmits the information directly to the emergency services to support or coordinate the measures or operations. Alternatively, it can also be provided that the corresponding information is output centrally or decentrally in the building, in particular displayed or printed.Alternatively, it can also be provided that the security unit is connected to the central control centers of the emergency services and that the information is transmitted to the control centers for the coordination or support of the operations and measures.

[0052] The method can also be provided for the application unit to comprise a pattern recognition means which, as part of the application-related and room-unit-related processing of the sensor signals, recognizes spatial and / or temporal patterns in the states and / or changes in state of the at least one room unit, wherein the application unit generates an output signal which depends on a pattern of a state and / or a change in state of the at least one room unit. For example, the pattern recognition means can recognize a presence and / or absence pattern over a certain period of time. However, depending on the design of the sensor units, the pattern recognition means can also identify movement patterns. It can also be particularly advantageous for the patterns to relate to a plurality of room units and their states.For example, a pattern may also relate to a predominant absence of living beings in the spatial units for a certain daily or other periodic period, so that the pattern recognition means are able to determine whether, for example, once or repeatedly, there is no presence of a living being in 80% or 90% of the spatial units detected by the sensor units.

[0053] Another particularly advantageous embodiment of the method provides that the application unit comprises a prediction means which, as part of the application-related and spatial-unit-related processing of the sensor signals, makes a prediction about a future state of at least one spatial unit. The application unit generates an output signal that depends on a future state of the spatial unit. This can, on the one hand, be a prediction of the presence of a living being, in particular a human, in the respective spatial unit, and, on the other hand, can also be a prediction regarding another parameter linked or linkable to the spatial unit.For example, the future temperature in a room unit can be deduced from current and past temperature values, or the future temperature of a room unit can be predicted and taken into account when generating the output signal of the application unit, for example to provide the control unit for controlling an air conditioning system with an optimized output signal so that the control unit can control or operate the building function, in particular the air conditioning of the room unit, in an optimized manner.

[0054] The prediction particularly takes into account the patterns recognized with the pattern recognition tools.

[0055] In the previous description of the system and the method, a large number of sensor modules and a large number of sensor units have been used. In a building context, in which a particularly large number of room units are to be monitored and / or analyzed, such a system and method offer particularly significant added value. This is also due to the fact that with an increasing number of sensor units, and thus a growing amount of available information, particularly reliable and far-reaching determinations can be made by means of the application unit and the device components that receive the output signal of the application unit. can beand building management can be aligned based on the findings. Nevertheless, the added value according to the invention can also be achieved if the system and / or method is equipped or operated with only one sensor module and / or one sensor unit. This is because, even with the application-specific and room-unit-specific processing of the sensor signals by means of the application unit, advantageous, integrative management of the room unit or the building can be achieved for a single sensor unit and, accordingly, a single room unit.

[0056] The invention further relates to an accommodation facility, in particular a hotel, comprising a sensor system as described above, wherein the room units comprise at least one hotel room and / or a room of a hotel room. The particular strength of the system according to the invention and thus also the particular further development with regard to the accommodation facility lies in particular in the fact that for the room units to which a sensor unit is assigned, the presence or absence of a living being, in particular a human, can be detected and determined with extremely high reliability, regardless of other factors such as movement, lighting conditions, or the like. This is achieved in particular when the sensor units are set up and designed to detect micro-movements, in particular to detect vital functions.However, absence detection or presence detection can significantly improve building management and thus the troubleshooting system. For example, in a bedroom of a hotel room monitored by a sensor unit of the sensor system according to the invention, the system can implement automatic light or lighting control, the trigger or control variable of which is the actual presence or absence of a living being, in particular a human. This means that, in contrast to known accommodation facilities and their building control or management systems, reliable and correct building management can be achieved even when guests are resting or sleeping. In addition to hotels, ships, such as cruise ships or other passenger vessels, can also be considered as accommodation facilities.Official or government accommodation facilities, such as correctional facilities or the like, can also constitute accommodation facilities according to the invention. In this context, for example, a cell as a spatial unit can be detected and / or monitored by a sensor module and / or a sensor unit.

[0057] A stable facility also encompassed by the invention, in particular a pet and / or farm animal stable, particularly preferably a horse stable, comprising a sensor system as described above can be realized in that the spatial units comprise at least one animal residence area, in particular a horse box. For the stable facility according to the invention, the integration of the described sensor system can be achieved in a particularly advantageous manner that building management is expanded and improved in a previously unknown manner. In addition to the automated dispensing of feed, which can be realized, for example, via a control unit connected to the application unit, and the automated or optimally planned cleaning of the lower residence areas, in particular horse boxes, the recording and monitoring of vital functions can also be used particularly advantageously for building management.In addition to particularly reliable detection of the presence or absence of an animal, particularly a horse, in the living area, the animal's health can be recorded and incorporated into building management when the animal is present. For example, it is possible for colic or similar illnesses in horses or similar animals to be detected based on their vital functions, and for a safety unit in the system to generate safety messages, for example to alert staff present in the stable facility or to alert or alert external bodies or persons, such as veterinary staff, about the changed vital functions or the detected illness. The same applies, for example, to a birth taking place in the stable facility.Here, by recording vital functions, for example by recording a new or additional, separate vital function in a room unit in which a vital function has already been recorded, the application unit and the system components connected to the application unit and supplied with the output signal of the application unit can conclude that a birth is taking place and corresponding building management precautions and processes can be triggered and / or carried out.

[0058] For a medical accommodation facility according to the invention, in particular a hospital and / or retirement and / or nursing home, with an above-described sensor system according to the invention, in which the room units comprise at least one patient or resident storage area, in particular a patient or resident bed, multi-level building management can be achieved in a particularly advantageous manner. As already described above in a related context, the sensor units of the system according to the invention, in particular when they are configured and designed to detect micro-movements and vital functions, enable the actual absence or presence of a person, in particular a patient or a resident, in the room unit to be detected with particularly high reliability.This allows for particularly advantageous and far-reaching building management to be implemented in a first stage of building management based solely on the presence or absence detected at any given time, as well as on the changes in presence and absence within the monitored room units. For example, advantageously with the inclusion of a pattern recognition tool and / or a prediction tool in the system's application unit, an attendance trend or a change in attendance across different room units can be detected and evaluated, and appropriate measures initiated based on this. For example, in a retirement and / or nursing home, the uninterrupted presence of a patient or resident in a storage area can be recorded and evaluated in order for the system to initiate or initiate measures that ensure a certain minimum level of mobilization of the residents and patients.In addition to the system's safety unit, the system's organizational unit or control unit can also be used for this purpose. For example, a patient bed or resident's bed can be automatically controlled by the control unit to make it easier for a resident or patient to get up or leave the bed. Alternatively or additionally, the organizational unit or safety unit can be used to alert nursing staff to the need to mobilize a resident or patient, and to organize the corresponding activities in a beneficial or optimized manner.

[0059] Similarly, in the medical accommodation facility according to the invention, the uninterrupted presence time in a room unit designed as a sanitary room or sanitary unit could be recorded and / or evaluated and, in this context, the system could also generate indications and / or take measures to provide a patient or resident with the necessary support and / or assistance if a predefined maximum stay time or presence time in a sanitary room or sanitary area is exceeded.

[0060] In a further stage of building management, in the context of a medical accommodation facility, the system could evaluate not only the mere presence or absence of a living being, in particular residents or patients, in a room unit, but also the recorded micro-movements, in particular the recorded and identified vital functions, so that, for example, the safety instructions generated by a safety unit include or contain medical information derived from the vital functions, which can be used by medical personnel in the diagnosis and / or treatment of the patients or residents.

[0061] In a meeting and / or conference facility according to the invention, which comprises the system according to the invention, wherein the room units comprise at least one meeting and / or conference room t, essentially the advantages described with reference to the accommodation facility can be achieved. Through reliable knowledge of the current use of the meeting and / or conference rooms, in particular through reliable knowledge of the presence or absence of living beings or people, and in particular through reliable recording of the number of people, improved control of the room functions can be enabled. Likewise, the system can achieve an optimized organization of the meeting and / or conference facility based on statistical evaluation, for example using the application unit, particularly in the case of long-term use.

[0062] In a workplace according to the invention, in particular an office unit, with a plurality of workstations, which comprises a sensor system according to the invention as described above and in which the room units comprise at least one room or area of the workplace assigned to a workstation, similar advantages and further developments can be realized in the basic concept as in the accommodation facilities and meeting and / or conference facilities according to the invention. Here, too, the highly reliable detection and recognition of presence or absence, based, for example, on micro-movements and / or vital functions, is a particularly advantageous basis for the building management of the workplace.An application unit of the system and the output signals can not only record the current usage of the room units, i.e., the workstations, and optimize building management based on the recorded usage, but can also perform a statistical evaluation, particularly by incorporating the pattern recognition and prediction tools of the application unit, which records usage over a longer period of time, determines or predicts the expected future usage, and adjusts or optimizes building management accordingly. The statistical evaluation by the application unit can result in significant cost savings.

[0063] With regard to the inventive uses of the inventive method for the building management of a disposal facility, a stable facility, a medical accommodation facility, a meeting and / or conference facility, and / or a workplace, reference is made to the preceding description of the corresponding devices. The uses of the method enable and implement the advantages and developments of the prior art already described with reference to the devices.

[0064] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings, which show: Fig. 1 shows a schematic representation of the structure of a sensor system according to the invention; Fig. 2 shows a schematic representation of a sensor unit according to the present invention; and Fig. 3 shows a flowchart of a method according to the present invention.

[0065] In the following description of the figures, the sensor system according to the invention and the method according to the present invention will be explained with reference to an application or use in a hotel building or the like. However, other possible applications are of course possible and offer the same, similar, or even additional advantages than those described below.

[0066] The Fig. 1 shows a sensor system 20 according to the present invention. The sensor system 20 comprises a plurality of sensor modules 02, each of which is assigned to a room unit 01. In the example in Fig. 4, a total of four room units 01 are shown.

[0067] For example, the room units 01 are intended to represent hotel rooms, whereby the room units 01 can be located on different floors of a hotel building. For the sake of simplicity, Fig. 1 Only four room units 01 are shown. However, the sensor system can be expanded to an unlimited number of room units. The sensor modules 02 arranged in the room units 01, i.e. in the hotel rooms, comprise a sensor unit 03 for detecting micro-movements and, in addition, a further functional unit 07. In the example of the Fig. 1The functional unit 07 is intended to be a smoke detector or smoke alarm of a generally known type. However, it is intended that the smoke alarm in the form of the functional unit 07 be arranged with the sensor unit 03 of the sensor module 02 in a common housing 08. This facilitates the integration of the sensor modules into the existing infrastructure, for example, the retrofitting of the sensor modules 02 into the existing hotel infrastructure. For this purpose, it can be particularly advantageous for the housing 08 to have a shape that is based on the functional unit 07, i.e., the smoke alarm.

[0068] In the presentation of the Fig. 1All sensor modules 02 of the room units 01 comprise a sensor unit and a further functional unit 07. Accordingly, all sensor units 03 are connected to a communications network 04, which in turn is connected to a central processing unit 05. The connection between the central processing unit 05 and the sensor modules 02 or sensor units 03 can be wired or wireless. Sensor signals from the sensor units 03 or information regarding sent and / or received sensor signals from the sensor units 03 can particularly preferably be transmitted to the central processing unit via the communications network 04. In addition, however, it can also be provided that the functional units 07 use the communications network 04 to also exchange data or information, in particular with the central processing unit or with devices connected to the central processing unit.

[0069] By means of the sensor units 03 for detecting micromovements, which are preferably designed as UWB sensors, micromovements in the spatial unit 01 can be detected. With the support of the connected central processing unit 05, it is particularly possible to detect and process micro-Doppler effects by creating a Doppler map and applying Fourier transformations. This in turn enables the detection of fundamental oscillations and harmonic overtones, by means of which micromovements of a living being, in particular a human, can be detected, which are triggered or caused on the body surface by the heartbeat or pulse. Based on such characteristic micromovements, the presence or absence of a living being, in particular a human, in the respective spatial units 01 can be inferred with particularly high certainty and reliability.

[0070] Consequently, with the sensor system 20 according to the invention, in particular by means of the sensor units 03 in conjunction with the central processing unit 05, the presence or absence of a living being, in particular a human being, in the example of Fig. 1 of a hotel guest, in room unit 01, i.e. in the hotel room.

[0071] The information about the presence and absence of hotel guests in the room units 01, as detected by the sensor units 03 and the central processing unit 05 via the micro-movements in the room units 01, is transmitted to the application units 06 connected to the central processing unit 05. The application units 06 are shown in the example of the representation of the Fig. 1represented as three individual, separate application units 06. Alternatively, the application units 06 could also be combined into a common application unit. It could also be provided to integrate the application units 06 into the central processing unit 05. The application unit 06 or the application units 06 can, for example, be connected to a memory unit 19 in which application-specific or application-related information and parameters are stored. These can be static as well as variable properties and parameters. For example, the memory unit 19 can store on which days of the year and at what time a sunrise and / or sunset occurs, or at what time of day a certain twilight value exists or is expected. Alternatively, information of a safety-related nature could also be stored in the memory unit 19.For example, it could be stored which room units 01, i.e. which hotel rooms, can be reached with a special rescue device, such as a rescue ladder. The storage unit 19 could also store the time or date in the past when certain room unit tasks, such as cleaning and / or housekeeping, were last performed. In addition to a connection to the storage unit 19, the application unit 06 or the application units 06 can also be linked to other information systems or measurement systems that supply the application unit 06 with current or situation-specific information about the room units 01 and / or the building as a whole.For example, the application unit 06 can be connected to the functional units 07, i.e. to the smoke detectors, in such a way that the status of the smoke detector of the functional unit 07 is known to the application unit 06 or can be queried by the application unit 06. Other application-specific dynamic or current information can also be queried by the application unit or made available to the application unit 06, for which purpose existing data connections and interfaces can be used or set up accordingly. For example, it can be provided that the application unit 06 is provided with an actual value of the room temperature of the room units 01. A temperature setpoint for the room temperature of the room unit 01 set by a hotel guest, i.e. a living being present or absent in the room unit 01, can also be transmitted to the application unit 06.

[0072] Other sensor signals from the Fig. 1 Sensor units not shown, which enable, for example, optical or spatial detection of the room unit 01, can be taken into account, for example to detect not only the presence but also the position, movement and / or acceleration of a living being.

[0073] Depending on the respective application unit, an application-specific output signal can be generated by the application unit 06 from the application-specific information and data as well as from the room unit-related information, in particular the information about the current presence or absence of living beings in the room units 01 as well as about the past absence and presence as well as periods of absence and presence of living beings in the room units 01. For example, the output signal can be designed such that in a room unit 01 in which a person or living being is detected as currently present via the corresponding micro-movements, a set target temperature of the room temperature of the room unit 01 deviates from a current actual temperature of the room temperature of the room unit 01.Such an output signal can be made available by the application unit 06 to a control unit 10, wherein the control unit 10 is set up to control at least one building function, in particular a room unit function, for example a room temperature of a room unit 01, so that the control unit 10 controls the building function, in particular the room unit function, as a function of the output signal of the application unit 06. In the example outlined above, for the application-specific output signal of the application unit 06, which relates to the difference between a target room temperature and an actual room temperature for a room unit 01 in which a person or living being is present, the control unit 10 can therefore generate control signals on the basis of the output signal of the application unit 06, which control signals are transmitted via the control unit 10. Fig. 1The control network 21 outlined above can be transmitted or forwarded to air conditioning devices arranged in the room units 01 in order to compensate for the difference between the target room temperature and the actual room temperature for those room units 01 in which a living being or person is detected as being present. If necessary, the application unit 06 and the control unit 10 can also be implemented as a common unit.

[0074] Alternatively or in addition to a control unit 10, an application unit 06 can also be connected to an organizational unit 12. The organizational unit 12 is intended, for example, to plan and coordinate building work, in particular room unit work, and thus improve the operation of the building in which the sensor system 20 is installed or make it more efficient. Accordingly, the application unit 06 can provide the organizational unit 12 with an output signal, which particularly relates to the current presence of living beings in the room units 01, as well as the past presences and absences, as well as presence phases and absence phases of living beings in the room units 01.In other words, the output signal of the application unit 06, which is connected to the organizational unit 12, can primarily reflect the presence of hotel guests in the respective hotel rooms or room units 01 and the occupancy of the hotel rooms or room units in the past, in particular on a previous night. Based on this output signal of the application unit 06, it can be provided that the organizational unit 12 creates a cleaning plan or housekeeping process that may change dynamically based on the sensor signals of the sensor units 03 in order to enable the hotel rooms, i.e. the room units 01, to be cleaned as time-effectively as possible and in a way that is pleasant and comfortable for the hotel guests. For this purpose, it can be provided that the organizational unit 12 is in turn connected to an output unit 13.The output unit 13 can be, for example, a printer, a screen, a smartphone, or the like. The output unit 13 serves to display or communicate the planning of the room unit work to the relevant workers or hotel employees who are to perform the work.

[0075] In addition, a Fig. 1A service unit (not shown) may be provided which suggests or issues possible services to a guest or living being located in the room unit, wherein the service is determined on the basis of the output signal of the application unit 06. For example, a hotel guest may be offered a wellness offer, such as a massage, within the room unit 01, i.e. the hotel room, or in another room unit of the hotel. However, an entertainment offer, such as a sightseeing offer, may also be made. In addition to the presence in the room unit 01, further static or dynamic information can also be used, which is transmitted to or made available to the application unit 06.For example, booking or registration information that indicates preferences or that can be used to infer personal preferences can be taken into account to generate an output signal from the application unit 06 that corresponds to the needs or wishes of the user or hotel guest.

[0076] Alternatively or additionally, it can be provided that an application unit 06 is connected to a security unit 14. The security unit 14 can be configured to generate security units and / or to coordinate and / or support rescue measures and / or to coordinate security or police operations. Based on the sensor signals from the sensor units 03 and the processing or evaluation to identify the presence or absence of living beings in the room units 01 based on the detected micro-movements, an output signal can be generated, for example, by the application unit 06, taking into account information about the accessibility of the respective room units using appropriate rescue equipment, which output signal is further processed by the security unit 14.For example, based on the output signal of the application unit 06, the security unit 14 can issue safety instructions to the hotel staff via the output unit 13, for example, in which hotel rooms or room units 01 a smoke detector or a functional unit 07 has been activated and, at the same time, a living being has been detected. Alternatively, however, it can also be provided that the security unit 14 is connected to a control center 15 of emergency services, and communication with the control center 15 takes place regarding which hotel rooms or room units 01 have hotel guests present and require evacuation via special rescue equipment, such as rescue ladders, in an emergency.Furthermore, it can be provided that the application unit 06 comprises a prediction means 16, which, as part of the application-related and room-unit-related processing of the sensor signals, makes a prediction about a future state of at least one room unit. For example, the prediction means 16 can be used to predict whether, in an emergency, for example a building fire, based on the vital functions of a hotel guest located in a room unit, it can be assumed that the hotel guest can evacuate independently or must be evacuated by someone else, for example because unconsciousness has already occurred or is predicted. In this case, corresponding warnings or coordination measures can also be generated via the security unit 16 and transmitted to the output unit 13 or the control center 15.

[0077] Alternatively or additionally, pattern recognition tools can be used, which are used in the representation of the Fig. 1 are not shown. The pattern recognition means can, for example, detect whether, in the event of a fire or other emergency, a hotel guest in room unit 01 displays a panicked, irrational, or uncoordinated reaction, so that the assistance and / or rescue measures can be tailored specifically to the hotel guest in order to alleviate or overcome the panic.

[0078] Fig. 2shows a schematic representation of a sensor module 02 comprising a sensor unit 03. In addition to the sensor unit 03, the sensor module 02 comprises a further functional unit 07, for example a smoke sensor. The sensor module 02 can also have control electronics 17. Furthermore, the sensor module 02 can comprise a power supply unit 18, in particular a rechargeable battery. Finally, the sensor module 02 can have a communication interface 23, which is set up, for example, for wireless communication. By combining the sensor unit 03 with a further functional unit 07, the sensor system according to the invention can be installed in a particularly space-saving manner. Furthermore, the sensor system can be retrofitted particularly easily and effectively if the sensor unit 03 is linked to a further functional unit 07, for example a smoke detector, in a common sensor module 02.It can be particularly advantageous to provide that the . Fig. 2 The merely indicated common housing 08 of the sensor module 02 has a shape that is oriented toward at least one further functional unit 07 of the sensor module 02. The sensor unit 03 preferably comprises a radar sensor 09, in particular a combined radar transmitter and receiver, which can be designed, for example, as a UWB transceiver. This makes it possible to detect micro-movements in a spatial unit with high spatial resolution using the sensor unit 03.

[0079] The Fig. 3shows a schematic flow diagram of the method according to the invention. In a first method step S 1, a state of the room unit is detected by a plurality of sensor modules, each of which is assigned to a room unit. In particular, radar signals are emitted and reflected radar signals are received using the sensor units 03. The corresponding sensor signals or information about the sensor signals are transmitted to a central processing unit 05 in a second method step S 2. The method steps S 1 and S 2 can be repeated continuously. In method step S 3, an application unit submits an information request to the central processing unit 05 in order to receive information about the micro-movements, in particular the presence of living beings, in the room units 01.In the subsequent method step S 4, corresponding information about the micro-movements in the room units is sent from the central processing unit 05 to the application units 06 and received accordingly by the application unit 06. In method step S 5, the application unit 06 accesses, in addition to the information about the micro-movements in the room units 05 received from the central processing unit 05, further static or dynamic, in particular application-related or room-unit-related information. Subsequently, in method step S 6, the application unit 06 creates an application-specific and room-unit-related output signal, which is then forwarded or transmitted to a control unit 10, an organizational unit 12, or a security unit 14 in a further method step S 7.In a concluding process step S8, the control unit can then initiate appropriate control of the building function or the room unit function, plan the building work, particularly the room unit work, and initiate appropriate coordination measures by emergency services or issue safety instructions by the security unit. After completing process step S8, the process can return to process step S3 by sending further requests to the central processing unit 05 from the application units. Reference symbol
