Description

[0001] The present invention relates to a control system for a building and a corresponding method. Technical area

[0002] Modern buildings often incorporate a variety of electrical systems. For example, modern buildings may have a controllable air conditioning system, a networked lighting system, an access control system, and the like.

[0003] Typically, such systems can be configured and operated using appropriate control devices. For example, a touchscreen can be mounted on a wall in a room of the building, which can be used to configure the systems.

[0004] A user must therefore actively use the respective control device to operate or control the electrical systems in the building.

[0005] DE 10 2009 056 152 A1 discloses an electronic system for wireless remote control of lighting. DE 10 2010 019 829 A1 discloses a method for controlling at least one lighting system of a motor vehicle. DE 10 2008 009 177 A1 discloses a control system for printing presses in which a user is identified. Disclosure of the invention

[0006] It is therefore an object of the present invention to provide an improved control for buildings.

[0007] Accordingly, the present invention discloses a control system and a method having the features specified in the independent claims. Description of the invention

[0008] The insight underlying the present invention is that people today typically carry at least one electronic device that emits wireless signals for data transmission. Such an electronic device can be, for example, a smartphone or a tablet PC or the like.

[0009] The idea underlying the present invention is to take this knowledge into account and to provide a way to use the wireless signals emitted by such devices to identify the respective person and to control the building.

[0010] The control system could, for example, be a building management system that features wireless communication interfaces. These allow the computing device to receive wireless signals from devices that carry living beings, such as people or animals.

[0011] The radio signals emitted by devices such as smartphones have a range of several meters. This makes it possible, for example, to wirelessly identify a person using the device's address when they are inside a building. The person does not need to actively hold a chip card or RFID token to a reader. The person can therefore be identified without their active intervention.

[0012] In the same way, an animal, such as a cat living in a house, can be identified. For this purpose, a device can be attached to the animal's collar, for example.

[0013] Once a person or animal has been identified, the computer can control various electrical systems in the house with knowledge of the identified person. For example, the computer can control the lights or, for example, a heating / ventilation system or similar in the building. Controlling the lights can include, among other things, turning them on, off, dimming them, or adjusting the color of the light. When adjusting the heating or ventilation, a desired temperature can be set in the building, for example.

[0014] If the living being is an animal, the computing device can also, for example, open a cat flap in a door or control a food dispenser.

[0015] It is obvious in this case that a computing device is not just a centralized computing device, such as a single server. Rather, a computing device can also be understood as a decentralized system, such as a plurality of distributed computing units combined into a virtual or cloud server.

[0016] Advantageous embodiments and further developments emerge from the subclaims and from the description with reference to the figures.

[0017] In one embodiment, the computing unit can be embodied in the form of individual computing elements or subordinate computing units that are arranged in the individual communication interfaces and / or the electrical systems. The information required to implement the functions of the computing device is therefore already stored in the individual communication interfaces and / or electrical systems. For example, the individual communication interfaces and / or electrical systems are sent assignment tables and logical links in a “commissioning” phase or a start-up phase of the system. During operation, no central computing unit is then required to recognize people or trigger actions, since processing takes place decentrally in the end devices. The assignment tables and logical links can assign identifiers to living beings or identifiers to the actions or functions to be carried out.control commands. The individual communication interfaces and / or electrical systems can therefore contain the same information, or parts thereof, that is present in a central computing device.

[0018] In one embodiment, the wireless communication interface may include a WLAN interface, a Bluetooth interface, a cellular interface, a ZigBee interface, a 6LoWPAN interface, and / or a Thread interface. Other proprietary protocols are also possible.

[0019] Bluetooth, Wi-Fi, and mobile phone signals each have a unique identifier that identifies the respective device. Bluetooth devices, for example, have a unique so-called Bluetooth address, which is a 48-bit value. This address is usually abbreviated BD_ADDR. WLAN devices, similarly, have a so-called MAC address, which also uniquely identifies the respective WLAN device. Mobile phone devices have a so-called "International Mobile Station Equipment Identity," or IMEI number, which uniquely identifies them. If a living being carries a device with one of the aforementioned interfaces, the respective device can therefore be uniquely identified. Possible devices that can be used to identify a person include smartphones with a Bluetooth and / or Wi-Fi interface, Bluetooth devices such as headsets, PCs, tablet PCs, or the like.

[0020] In one embodiment, the wireless communication interfaces may be at least partially integrated into the electrical systems in the building.

[0021] In one embodiment, the wireless communication interfaces can be configured to merely listen for wireless signals from the devices. Thus, the devices do not need to explicitly communicate with the respective wireless communication interface. Rather, it is sufficient for the respective device to transmit data.

[0022] According to the invention, the control system has a memory configured to store an association between the possible identifiers and the respective living being. Furthermore, the computing device is configured to read information about the living being corresponding to an extracted identifier from the memory in order to identify the living being. If the association between the identifiers of the individual devices or transmitters and a person is stored in a memory, this association can be flexibly adapted and expanded. In this way, new people or animals, for example, can be very easily added to the system.

[0023] According to the invention, specifications for controlling the electrical systems are stored in the memory for each living being. Furthermore, the computing device is designed to control the electrical systems based on the respective specifications after a living being has been identified. For example, if a person has been identified, the individual electrical systems can be controlled according to the specifications of the respective person, i.e. according to the person's preferences. To enter the specifications, a web-based interface, e.g. an HTML page, can be provided by the computing device, via which the specifications can be entered. A user can call this up, e.g., using a PC, a tablet PC, or a smartphone. The interface can also be installed, e.g., as a native application or app on the PC, tablet PC, or smartphone. Alternatively, the control system can also have a separate configuration unit, e.g.a wall-mounted touchscreen or the like.

[0024] According to the invention, the default settings include lighting settings, temperature settings, heating settings, and ventilation settings. Different default settings are also stored for different times of day, days of the week, and seasons. This enables very detailed and granular control of the building's electrical systems. For example, a user can specify different room temperatures for winter and summer. A user can also specify temperature defaults for workdays, e.g., Monday to Friday, and different temperature defaults for Saturday and Sunday.

[0025] According to the invention, the wireless communication interfaces are arranged in different rooms of the building. Furthermore, the computing device is designed to determine in which of the rooms the living being is located based on a signal strength with which the individual wireless communication interfaces receive the wireless signal. Finally, the computing device is further designed to control only the electrical systems in the room in which the living being is located. This enables targeted tracking of the person in the building and corresponding control of the electrical systems. For example, lighting in a room can be switched on and adjusted according to the specifications when a person enters a room. However, the computing device can also, for example, simultaneously control the lighting in adjacent rooms accordingly.In the same way, a light can be turned off again after the person has left the room. The light can also be turned off after a specified time, for example, after the person has left the room.

[0026] In one embodiment, the computing device can be configured to control a building's telephone system such that calls for an identified living being are routed to a telephone in the room in which the identified living being is located. This significantly simplifies contacting a person by telephone, particularly in office buildings with multiple rooms, for example, if they have left their usual office. This eliminates the need to page the person, and the call is automatically routed to the appropriate room.

[0027] In one embodiment, the computing device can be configured to output an alarm signal when an identifier is extracted from a wireless signal for which no assignment is stored in the memory, or for which the memory contains information that the respective person is not permitted to enter the building. This allows the control system to also be used as an alarm system. If an unauthorized person attempts to gain access to the building, for example, while carrying their smartphone, this can be detected by the control system and reported to a security service, for example.

[0028] In one embodiment, the computing device can be configured to emit the alarm signal only at predetermined times, particularly at night. During the day, office buildings may be occupied by a large number of people who, for example, do not work in the office building but are there to run errands. This could lead to a large number of false alarms or false alarm messages or alarm signals if these people carry mobile phones. If the generation of the alarm signal is limited to certain times, e.g., outside of business hours, these false alarms can be avoided.

[0029] The memory can also store, for example, the time of day a person is permitted to be in the building. The computer can then issue an alarm if a person is in the building outside of the authorized times.

[0030] The above embodiments and further developments can be combined with one another as desired, where appropriate. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention not explicitly mentioned above or described below with regard to the exemplary embodiments. In particular, those skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention. Short description of the drawings

[0031] The present invention will be explained in more detail below with reference to the exemplary embodiments shown in the schematic figures of the drawings. In the drawings: Fig. 1 is a block diagram of an embodiment of a control system according to the invention in a building; Fig. 2 is a block diagram of an embodiment of a control system according to the invention in a building; and Fig. 3 a flowchart of an embodiment of a method according to the invention.

[0032] In all figures, identical or functionally identical elements and devices have been provided with the same reference numerals, unless otherwise stated. Embodiments of the invention

[0033] Fig. 1 shows a block diagram of a control system 1-1 according to the invention in a building 2.

[0034] Building 2 has two floors, 20 and 21. The upper floor, 20, has a left room, 22-3, a middle room, 22-4, and a right room, 22-5. The lower floor, 21, has a left room, 22-1, and a right room, 22-2.

[0035] In the right-hand room 22-2 of the lower floor 21, a person 6-1 is located with a smartphone 15-1. The smartphone 15-1 can transmit data according to a mobile communications standard, the Wi-Fi standard, or the Bluetooth standard. Each of these standards requires the smartphone 15-1 to transmit a unique identifier 7-1, e.g., a MAC address, a Bluetooth address, an IMEI, or the like, with each data transmission, which can be used to identify the smartphone 15-1.

[0036] A plurality of electrical systems 8-1 to 8-8 are installed in the building. A lamp 8-5 and a ventilation system 8-7 are arranged in room 22-1. A lamp 8-6 and a heater 8-8 are arranged in room 22-2. A lamp 8-1 is arranged in room 22-3. Two lamps 8-2 and 8-3 are arranged in room 22-5. Finally, a lamp 8-4 is arranged in room 22-5. It is understood that the arrangement, number, and type of electrical systems 8-1 to 8-8 were chosen merely as examples and serve merely to illustrate the present invention. Depending on the application, the number, type, and arrangement of the electrical systems may therefore differ from that shown here.

[0037] An electrical system is defined as any system that can be controlled electrically. For example, heater 8-8 could be a thermally operated heater with an electronic control system.

[0038] The electrical systems 8-1 to 8-8 are communicatively connected to one another and to a computing device 4-1 via a first data network 17-1.

[0039] Via the first data network 17-1, the computing device 4-1 can thus transmit control commands to the electronic systems and receive corresponding feedback from them. The first data network 17-1 can be, for example, an Ethernet network, a DALI network, a KNX network, a PROFIBUS network, or any other type of network. In particular, the first data network 17-1 can be a network that transmits its data via the supply lines of the electrical systems 8-1 to 8-8.

[0040] The computing device 4-1 is coupled to a second data network 17-2. The second data network 17-2 connects the computing device 4-1 to five wireless communication interfaces 3-1 to 3-5. Each of the wireless communication interfaces 3-1 to 3-5 is located in one of the rooms 22-1 to 22-5.

[0041] The separation of the two data networks 17-1 and 17-2 in the embodiment of the Fig. 1 is merely exemplary. In a further embodiment, the two data networks 17-1 and 17-2 can be configured, for example, as a single data network. In a further embodiment, the computing device 4-1 can be coupled to the wireless communication interfaces 3-1 to 3-5 via separate connections or wirelessly.

[0042] The wireless communication interfaces 3-1 to 3-5 of the Fig. 1 are designed as combined WLAN, Bluetooth, and mobile radio interfaces. They can therefore receive and evaluate wireless signals 5-1 or forward them to the computing device 4-1 that comply with the WLAN standard, the Bluetooth standard, or a mobile radio standard, such as GSM, UMTS, or LTE.

[0043] As already explained above, a person 6-1 is located in room 22-2 with a smartphone 15-1 that emits a wireless signal 5-1 with an identifier 7-1. This signal 5-1, or the identifier 7-1, can be received by the wireless communication interface 3-5 and forwarded to the computing device 4-1. This computing device extracts the identifier 7-1 of the smartphone 15-1 from the signal 5-1 and indirectly identifies the person 6-1 using this identifier 7-1.

[0044] Once the computing device 4-1 has identified the person 6-1, it controls the electrical systems 8-1 to 8-8 of the building 2 based on this knowledge. For example, the computing device 4-1 can control the light 8-6 in the room 22-2 according to the specifications set by the person 6-1. These specifications can, for example, relate to the brightness and / or color of the light or the like. The computing device 4-1 can also, for example, control the heating 8-8 so that the temperature in the room 22-2 is the temperature desired by the person 6-1.

[0045] If more than one of the wireless communication interfaces 3-1 to 3-5 receives the wireless signal 5-1 of the smartphone 15-1, the computing device 4-1 can, in one embodiment, evaluate the signal strength with which the wireless signal 5-1 is received at the individual wireless communication interfaces 3-1 to 3-5. The computing device 4-1 can then determine the position of the smartphone 15-1 and thus of the person 6-1 based on the individual signal strengths. For this purpose, the computing device can, for example, use a triangulation technique. In one embodiment, the computing device can also use the propagation times of the wireless signal 5-1 to the individual wireless communication interfaces 3-1 to 3-5 for this purpose.

[0046] In one embodiment, the computing device 4-1 can also assign the position of the person 6-1 to the room 22-1 to 22-5 in which the signal from the smartphone 15-1 is received most strongly. Furthermore, a dedicated detection system, e.g., with cameras or infrared motion detectors, can also be used to detect the position of the person 6-1. In particular, a camera-based system can also identify people, e.g., with the help of image recognition algorithms.

[0047] Fig. Figure 2 shows a block diagram of a control system 1-2 according to the invention in the building 2. The building 2 is identical to the building 2 of the Fig. 1. In building 2 of the Fig. 2, only one additional telephone system 12 is installed. A first telephone 13-1 of the telephone system 12 is installed in room 22-3, while a second telephone 13-2 of the telephone system 12 is installed in room 22-1.

[0048] The control system 1-2 further extends the computing device 4-1 of the Fig. 1 is a memory 9. Memory 9 has an assignment 10-1 to 10-n for each of the individual identifiers 7-1 to 7-n. The assignments 10-1 to 10-n identify the individual persons identified by the respective identifiers 7-1 to 7-n.

[0049] Furthermore, the memory 9 stores the specifications 11-1 to 11-n of the respective person for the control of the electrical systems 8-1 to 8-4 for the individual assignments 10-1 to 10-n. The content of the memory 9 is in Fig. 2 is shown merely as an example in a table. It is understood that the memory 9 can be configured as any type of memory, e.g., as a file, a database, or the like.

[0050] For example, the settings 11-1 to 11-n can specify a brightness desired by the person for controlling the lamps 8-1 to 8-6. The settings 11-1 to 11-n can specify separately for each room 22-1 to 22-5 how the electrical systems 8-1 to 8-n in the respective room 22-1 to 22-5 are to be controlled. The settings 11-1 to 11-n can also be stored separately for different times of day, days of the week, or seasons, for example. This allows the user to fine-tune the settings 11-1 to 11-n.

[0051] In Fig. 2, person 6-2 is in room 22-1 and is also carrying a smartphone 15-2.

[0052] For example only, let us assume that person 6-2 has an office in room 22-3. Telephone 13-1 in room 22-3 is therefore the telephone 13-1 through which person 6-2 can usually be reached. If person 6-2 is located, as in Fig. 2, now not in her office but in another room, room 22-1, the person 6-2 cannot be reached by telephone.

[0053] However, with the help of the computer 4-2, the telephone system 12 can be controlled so that it automatically forwards calls for the telephone 13-1 to the room in which the computer 4-2 has registered the corresponding person 6-2. In the case of Fig. 2, calls for telephone 13-1 would therefore be automatically forwarded to telephone 13-2.

[0054] The computing device 4-2 can further generate an alarm signal 14 if an identifier is extracted from a wireless signal 5-2 that does not correspond to any of the identifiers 7-1 to 7-n stored in the memory 9. For example, if a person with a smartphone enters the building 2 without authorization, this can be detected and a corresponding alarm triggered. To avoid a false alarm, the computing device 4-2 can, for example, only issue the alarm signal 14 once it has determined the position of the respective person, e.g., by triangulation (see description of Fig. 1), and this position is located in building 2. The generation of the alarm signal 14 can, for example, be restricted to specific times or days of the week, as already described above. In one embodiment, the memory for a respective identifier 7-1 to 7-n can also explicitly state that the respective person is not permitted to enter building 2.

[0055] Fig. 3 shows a flowchart of a method according to the invention for controlling a building 2.

[0056] In a first step S1, the method provides for receiving a wireless signal 5-1, 5-2 from devices 15-1, 15-2 carried by living beings 6-1, 6-2. For example, people can carry a smartphone 15-1, 15-2, a tablet PC, or the like, which transmit wireless signals 5-1, 5-2.

[0057] In a second step S2, an identifier 7-1 to 7-n is extracted from the received wireless signals 5-1, 5-2. The identifier uniquely identifies the respective device 15-1, 15-2 and thus enables direct identification of the device 15-1, 15-2 and thus indirectly identification of the person carrying the device 15-1, 15-2.

[0058] Consequently, the method provides a third step S3 in which the respective living being 6-1, 6-2 is identified based on the extracted identifier 7-1 to 7-n.

[0059] Finally, in step S4, electrical systems 8-1 to 8-8 in building 2 are controlled based on the information about the identified living being 6-1, 6-2. For example, lamps or lights 8-1 to 8-6 as well as ventilation systems 8-7 and heaters 8-8 can be controlled.

[0060] To receive the wireless signals 5-1, 5-2, a number, i.e., one or more, of communication interfaces 3-1 to 3-5 can be used. These can be configured, for example, as WLAN interfaces and / or Bluetooth interfaces and / or mobile radio interfaces or the like and can also be arranged, for example, in the electrical systems 8-1 - 8-8 or dedicated networked nodes.

[0061] In one embodiment, the method can provide for storing an assignment 10-1 to 10-n between the possible identifiers 7-1 to 7-n and the respective living being 6-1, 6-2. This assignment 10-1 to 10-n can be made, for example, during commissioning of a building 2. It is understood that such assignments 10-1 to 10-n can also be stored during operation of the building 2.

[0062] In order to identify the living being 6-1, 6-2, the respective assignment 10-1 to 10-n to the extracted identifier 7-1 to 7-n is then read out.

[0063] In one embodiment, specifications 11-1 to 11-n for controlling the electrical systems 8-1 to 8-8 can be stored for each living being 6-1, 6-2. These specifications 11-1 to 11-n can be used after a living being 6-1, 6-2 has been identified to control the electrical systems 8-1 to 8-8. For example, lighting settings and / or temperature settings and / or heating settings and / or ventilation settings can be stored in the specifications 11-1 to 11-n.

[0064] In one embodiment, defaults 11-1 to 11-n may be stored for different times of day and / or days of the week and / or seasons.

[0065] In a further embodiment, the wireless signals 5-1, 5-2 can be received in different rooms of the building 2, and based on a signal strength and / or a propagation time with which the wireless signals 5-1, 5-2 are received, it can be determined which of the rooms the living being 6-1, 6-2 is located in. The electrical systems 8-1 to 8-8 can then only be controlled in the room in which the living being 6-1, 6-2 is located.

[0066] In one embodiment, a telephone system 12 of the building 2 can be controlled such that calls for an identified living being 6-1, 6-2 are transferred to a telephone 13-1, 13-2 in the room in which the identified living being 6-1, 6-2 is located.

[0067] Finally, in one embodiment of the method, an alarm signal 14 can be issued when an identifier 7-1 to 7-n is extracted from a wireless signal 5-1, 5-2 for which no assignment 10-1 to 10-n is stored or for which the information is stored that the respective person is not permitted to enter the building 2. In this case, the alarm signal 14 can be issued, in particular, only during predetermined time periods, especially at night.

[0068] Although the present invention has been described above using preferred embodiments, it is not limited thereto, but can be modified in a variety of ways. In particular, the invention can be changed or modified in a variety of ways without deviating from the essence of the invention.
