Description

Building technology element, building control system comprising the same and method for controlling a device

[0001] The invention relates to a building technology element, a building control system comprising the same and a method for controlling a device, as well as wireless communication of the building technology element with the device.

[0002] In a building control system of a residential and / or commercial building, building technology elements are networked with the building control system via communication lines for monitoring, control, regulation, and / or optimization. These building technology elements can include sensors (such as motion and / or presence detectors, brightness and / or air pressure sensors, air quality sensors such as temperature, humidity, VOC, CO2, or combinations thereof), actuators (such as lighting controls, alarm systems, heating and shutter controls), and other technical systems (e.g., multimedia devices such as televisions, DVD players, or stereo systems). The building control system can be connected to an external communications network, such as the Internet or a mobile network, which allows the building technology elements to be controlled and adjusted externally (e.g., via a homeowner's mobile device).The building control system can have a central unit for connecting to external networks, for example, a KNX IP gateway. However, the building control system can also autonomously regulate or control technical processes in a building system or within a company, based on the data acquired by sensor elements. Frequently used building control systems are based on bus systems such as the decentralized KNX bus system, which connects the sensors and actuators in a building control system via communication lines (i.e., networks them via communication lines that enable wired communication). However, integrating wirelessly communicating devices into such a KNX bus system outside of a KNX-RF radio system is not easily possible.

[0003] If, for example, a building contains both devices with the KNX bus system and devices that communicate wirelessly with each other (e.g. via Bluetooth), the exchange of information between these two groups of devices is very difficult. This is cumbersome and requires additional, expensive hardware. Special gateways (hardware interface devices) are used to enable communication as protocol converters. However, such gateways are usually housed as DIN rail devices in a control cabinet, which, in the case of metal control cabinets, negatively impacts the radio signal strength and thus impairs the exchange of information. Furthermore, the distance of the wirelessly communicating devices from such a control cabinet affects the radio connection; if the devices are too far apart (for example, solar lights in the garden of a residential building), the radio signal strength also decreases.

[0004] The object of the present invention is therefore to provide an improved integration of wirelessly communicating devices into a wired building control system.

[0005] This object is achieved by the building technology element according to claim 1 and by the subject matter of the independent claims. Further advantageous embodiments and refinements of the invention are set forth in the subclaims.

[0006] In particular, this object is achieved by a building technology element in a wired building control system, wherein the building technology element comprises: a radio network transceiver with a limited transmitter range, a radio network interface connecting the building technology element for wireless data exchange with a system of wirelessly interconnected devices located within transmitter range, a communication interface connecting the building technology element for wired data exchange with the wired building control system, and a processing unit. The processing unit is adapted to control the exchange of data between the system of wirelessly interconnected devices and the building control system and to manage the data assigned to the respective devices.

[0007] Such a building technology element serves as an intermediary or gateway that enables the exchange of data between the wired building control system and the system of wirelessly connected devices. It integrates the wirelessly communicating devices into the building control system. In other words, the building technology element enables the The building control system allows the devices to be accessed and information exchanged. Furthermore, the building technology element manages the data associated with the devices to efficiently transmit corresponding information from the central control unit to the corresponding devices.

[0008] The building technology element can advantageously function as a master device, controlling the system's devices as slave devices. In other words, the building technology element represents the building control system (or an interface gateway) and can regulate, monitor, administer, mediate, and manage the data exchange between the devices and the central control unit, or act as an intermediary in the data exchange.

[0009] In this context, the processing unit can process the data received from a device of the system. The processing unit can be adapted to translate the wireless system protocol associated with the received data into a wired protocol of the building control system and to transmit the processed data to the wired building control system via the communication interface. The data received from the device can, for example, comprise current operating parameters of the device. The processing unit can therefore function as a software-based protocol converter, which makes it possible to provide data such as operating parameters of a device from a wireless system to the wired building control system.

[0010] The processing unit can also process the data from the wired building control system. It can be adapted to translate the wired building control system protocol associated with the received data into a wireless system protocol and transmit the processed data to a device in the system via the radio interface. The received data can include control signals for the device. The processing unit, acting as a protocol converter, can thus also transmit or relay control signals from the wired building control system to the system of wirelessly connected devices. For the devices, the building technology element can act as a master, controlling the devices (slaves) using the control signals.

[0011] Integrating software-based gateway functionality into the building technology element can enable information to be transferred between the wired and wireless protocols of the building technology element without additional hardware. In other words, there is no need for hardware-based gateways that must be subsequently installed into the building technology elements or integrated into the building control system as DIN rail devices.

[0012] The processing unit can further be adapted to assign an identification (e.g., an address) uniquely assigned to the building control system to the functions of a device in the system during a registration process and to transmit this identification via the communication interface to the building control system for registration or registration in a register. Furthermore, the processing unit can store the identifications assigned to the devices in the system in an association table along with the respective system addresses of the devices. This allows any number of new devices to be integrated into the system, with the processing unit managing the corresponding device data using the association table.

[0013] In one embodiment, the building control system can have a registration unit for integrating additional building technology elements. For example, the registration unit can receive the uniquely assigned identification or group identification of a device in the system via a system communication interface and register it. The registration unit can be configured as an additional computer unit that can be temporarily integrated into the building control system and registers corresponding devices. It can also be configured as a control unit that is permanently integrated into the building control system.

[0014] The processing unit can also be adapted to receive control commands sent by the building control system and addressed to a device in the system, and forward them to the corresponding device. The association table can be used or assisted in transmitting the data to the corresponding devices. The group address assigned to the corresponding function can be easily linked via the association table.

[0015] The building technology element can be designed as an actuator and / or as a sensor.

[0016] The actuator can be designed to act on a lighting system, a heating system or a ventilation system in a room of a building assigned to the actuator and / or an environment of the building assigned to the actuator.

[0017] The sensor can also be a brightness sensor, a temperature sensor, a humidity sensor, an air pressure sensor, a CO2 sensor, a VOC sensor, a motion and / or presence detector, or a combination of different sensors.

[0018] The system of wirelessly connected devices can be designed as a mesh radio network and include a lighting system, a heating system, or a ventilation system.

[0019] For example, such a mesh wireless network could be a "Bluetooth Mesh" network, which is a standard for computer mesh networks and is based on Bluetooth Low Energy (BLE). Bluetooth Mesh enables communication between many devices using the Bluetooth wireless protocol.

[0020] In this context, the radio interface of the building technology element can be a Bluetooth mesh interface, via which data can be received from and sent to the devices in the system.

[0021] Furthermore, the communication interface can be a KNX bus interface or an IP interface.

[0022] Likewise, a protocol of the building control system can be a KNX protocol and a protocol of the system of wirelessly connected devices can be a Bluetooth mesh protocol.

[0023] Using the configuration described above, the data received from the system's devices is transmitted to the building control system via a building technology element acting as an intermediary. This allows for efficient integration of the wireless system's data and devices into the building control system via the building technology element. Implement a building control system. No additional costly hardware is required, reducing additional costs.

[0024] The above object is also achieved by a computer-implemented method for controlling a device in a system of wirelessly interconnected devices, comprising the steps of: connecting a radio interface of the device to a radio interface of a building technology element in a building control system for exchanging data, receiving the data from the building technology element of the building control system via the radio interface of the device, wherein the data comprises control signals for controlling the device.

[0025] This method makes it possible to control system devices that are not integrated into the building control system. For example, as described above, this eliminates the need for additional hardware in the form of cabling that would otherwise be required to ensure communication between the system and the building control system. The building technology element acts as a master, transmitting control signals to the devices or slaves or making data from the wireless network available to the wired building control system.

[0026] The above object is also achieved by a computer program comprising instructions which, when the program is executed by a device of a system of wirelessly interconnected devices, cause the device to carry out the method described above.

[0027] The above object is also achieved by a computer-readable medium comprising instructions which, when executed by a device of a system of wirelessly interconnected devices, cause the device to carry out the method described above.

[0028] The above object is also achieved by a data processing device comprising means for carrying out the above method.

[0029] The invention is explained in more detail below with reference to the accompanying drawings, which schematically show:

[0030] Fig. 1 is a schematic view of an embodiment of a building technology element in a building control system according to the present invention;

[0031] Fig. 2 is a schematic view of an embodiment of a building control system according to the present invention;

[0032] Fig. 3 is a flowchart of an embodiment of a method for controlling a device in a system of wirelessly interconnected devices according to the present invention; and

[0033] Fig. 4 shows a schematic view of an embodiment of an association table.

[0034] Fig. 1 shows a simplified schematic view of an embodiment of a building technology element 10 in a wired building control system 100 according to the present invention. The building technology element 10 comprises a radio network transceiver 12, a radio interface 14, a communication interface 16, and a processing unit 18.

[0035] The radio network transmitter-receiver 12 has a limited transmitter range (or a defined limited transmission power) and receives / transmits data D only within a specific area surrounding the building technology element 10.

[0036] For this purpose, the radio interface 14 connects the radio network transceiver 12 to a system 200 located within transmitter range, comprising wirelessly or cordlessly connected devices 20 for the wireless or cordless exchange of data D. This is illustrated in Fig. 1 in simplified form by a corresponding arrow. The building technology element 10 can communicate with any device 20 of the system 200. Fig. 1 shows two devices 20 connected to the building technology element 10. For example, control commands can be transmitted to the devices 20 via the building technology element 10, which will be described in more detail later.

[0037] Via the communication interface 16, the building technology element 10 is further connected to the wired building control system 100 for the wired or cabled exchange of data D. The building control system 100 can be designed as a decentralized system with additional building technology elements 10, which exchange data D with the building technology element (10). This is illustrated in Fig. 1 by corresponding arrows. A central building control system 100 with a stationary control unit 120, which will be described later, is also possible.

[0038] The processing unit controls an exchange of data D between the system 200 of wirelessly connected devices 20 and the building control system 100. In addition, it manages the data assigned to the respective devices 20.

[0039] In other words, the processing unit 18 establishes and regulates data exchange between the system 200 based on wireless or cable-based communication and the building control system 100 based on wired or cable-based communication. The building technology element 10 thus serves as an intermediary (or gateway or bridge) between these two systems 100, 200. This allows data D to be transferred from the system 200 to the building control system 100 and vice versa, or the devices 20 of the system 200 to be integrated into the building control system 100. No additional hardware is required for this. The radio network transceiver 12, the radio network interface 14, and the communication interface 16, together with the processing unit 18, enable efficient data exchange.

[0040] The building technology element 10 can function as a master device, which controls the devices 20 of the system 200 as slave devices. This is also illustrated in a simplified manner by the corresponding arrows in Fig. 1.

[0041] In detail, the processing unit 18 can process the data D received from a device 20 of the system 200, translating the wireless protocol of the system 200 associated with the received data D into a wired protocol of the building control system 100. It can then transmit the processed data D to the building control system 100 via the communication interface 16. For example, the data processed in the building control system 100 configured as a central system Data D is transmitted to the control unit 120. Furthermore, the data D processed in the building control system 100, which is designed as a decentralized system, can be transmitted to other building technology elements 10. In another example, the data D received by the device 20 can include current operating parameters of the device 20.

[0042] For example, operating parameters of a device 20 embodied as a light, such as the current state of the light (on / off) or a dimming level of the light 20, can be transmitted to a building technology element 10, which is embodied, for example, as a motion and / or presence detector, and forwarded to the building control system 100 after protocol translation. Fig. 2 shows a simplified representation of the building control system 100 with the light 20 and the motion and / or presence detector 10 in a room R1 of a building G. The wireless data exchange between the light 20 and the motion and / or presence detector 10 is indicated by the wavy lines. This example will be explained in more detail later.

[0043] Furthermore, the processing unit 18 can process the data D received from the building control system 100, translating the wired protocol of the building control system 100 associated with the received data D into a wireless protocol of the system 200. It can then transmit the processed data D to a device 20 of the system 200 via the radio interface 14. In another example, the received data D can include control signals for the device 20.

[0044] Following the above scenario, it is possible, for example, to forward a control signal for the dimming level of the luminaire 20 to the luminaire 20 via the motion and / or presence detector 10. The processing unit 18 (not shown in Fig. 2) of the motion and / or presence detector 10 can translate the control signal for the luminaire 20, which is written in the wired protocol, into the wireless protocol of the system 200 and forward it to the radio interface 14 (not shown in Fig. 2) of the motion and / or presence detector 10.

[0045] The processing unit 18 can thus serve as a protocol converter (ie, have a software-based gateway functionality) that converts the wireless protocol of the data D from the system 200 into the wired protocol of the building control system 100 and vice versa. This allows devices 20 based on wireless communication to be integrated into the building control system 100. This eliminates the need for additional hardware and cabling. The wireless connection between the devices 20 and the building technology element 10 is also better than in conventional solutions with a gateway designed as a DIN rail in a control cabinet. Furthermore, by integrating the devices 20 into the building control system 100, additional building technology elements 10 can be dispensed with, which further saves control cables.

[0046] In one embodiment, in a registration process, the processing unit 18 can assign an identification uniquely associated with the building control system 100 to a device 20 of the system 200 and transmit this identification to the building control system 100 for registration via the communication interface 16. For example, a universally unique identifier (UUID) or a group address ADD_200_1, ..., ADD_200_4 of the system 200 can be assigned an address of the building control system ADD_100_1, ..., ADD_100_4. For example, in one embodiment, a UUID or group address ADD_200_1, ..., ADD_200_4 of a Bluetooth mesh system 200 assigned to a group of devices 20 such as a corridor group or ground floor group can be assigned a UUID or KNX address ADD_100_1, ..., ADD_100_4 corresponding to the building control system.The processing unit 18 can store the identifications ADD_100_1, ..., ADD_100_4 assigned to the devices 20 of the system 200 in an association table Tab together with the respective UUID or group addresses of the devices 20. Such an association table Tab is shown schematically in Fig. 4. The assignment of the UUID or group addresses ADD_200_1, ..., ADD_200_4 assigned to the devices 20 of the system 200 to the addresses ADD_100_1, ..., ADD_100_4 of the building control system 100 is illustrated in a simplified manner.

[0047] For example, the building technology element 10 acting as the master can send requests to the system 200 at set intervals to check whether new devices 20 have been added and need to be registered. Likewise, new devices 20 can send a corresponding registration request to the building technology element 10 after installation. The processing unit 18 can then store the data D of the new devices, such as the UID or group addresses ADD_200_1, ..., ADD_200_4, in the association table Tab.

[0048] In a further embodiment, the building control system 100 can have a registration unit 120 for integrating additional building technology elements 10. The registration unit 120 can receive the identification or group identification uniquely assigned to a device 20 of the system 200 via a system communication interface 110 and register it. The registration unit 120 can be configured as a computer unit that is temporarily connected to the decentralized building control system 100. As already described above, in another embodiment, it can be configured as a control unit 120, in which case the building control system functions as the central system.

[0049] In this context, the processing unit 18 can receive the control commands sent by the building control system 100 and addressed to a device 20 of the system 200 and forward them to the corresponding device 20.

[0050] Through the association table Tab, the processing unit 18 can assign the data D received from the building control system 100, such as the control unit 120, to the corresponding devices 20 and forward them to the devices 20 after the protocol translation.

[0051] The building technology element 10 can be designed as an actuator and / or as a sensor.

[0052] The building technology element 10 designed as an actuator can, for example, act on a lighting system, a heating system or a ventilation system in a room R1, R2 of a building G assigned to the actuator and / or an environment of the building G assigned to the actuator.

[0053] Likewise, the sensor can be a brightness sensor, a temperature sensor, a humidity sensor, an air pressure sensor, a CO2 sensor, a VOC sensor, a motion and / or presence detector, or a combination of the various sensors as described above.

[0054] The system 200 of wirelessly connected devices 20 can be designed as a mesh radio network, which is shown in simplified form in Fig. 1. It can a lighting system, a heating system, or a ventilation system. However, this is only an example, and other wirelessly connected devices 20 can form the system 200.

[0055] The radio interface 14 can also be a Bluetooth mesh interface.

[0056] Bluetooth Mesh is based on Bluetooth Low Energy (BLE), formerly Bluetooth Smart, a wireless technology that allows 20 devices to be networked in an environment, i.e. with a range of about 10 meters.

[0057] The communication interface 16 can be a KNX bus interface or an IP interface.

[0058] In this context, a protocol of the building control system 100 may be a KNX protocol and a protocol of the system 200 of wirelessly interconnected devices 20 may be a Bluetooth mesh protocol.

[0059] Consequently, the processing unit 18 can mediate between the KNX protocol and the Bluetooth mesh protocol with the software-based gateway functionality in order to efficiently control communication between the system 200 and the building control system 100.

[0060] Fig. 2 shows an exemplary embodiment of the building control system 100 according to the invention with several building technology elements 10. Here, the building control system 100 can be designed as a central or decentralized system as described above.

[0061] In the building control system 100 designed as a central system, the system communication interface 110 can connect the building control system 100 with building technology elements 10. This is also illustrated in Fig. 1, wherein the further building technology elements 10 are shown in dashed lines. These elements 10 can also exchange data D with devices 20 via their respective radio interfaces 14 (not shown in Fig. 1) and transmit them to the control unit 120, thus functioning as a data hub or data transmission interface. In this case, the device connected to the devices 20 The building technology element 10 shown in Fig. 1 is representative of the other building technology elements 10. The system 200 can also comprise additional devices 20, or there can be several systems 200 with which a building technology element 10 according to the invention can communicate. The building technology element therefore works as a central data distribution interface or as a central data distribution point or as a central mail room between the system 200 and the control unit 120. In doing so, it collects the data from the devices 20 transmitted via the radio protocol and transmits it to the control unit 120, with the building technology element 10 representing the control unit 120 here.Furthermore, the building technology element 10 intercepts control or command data packets via the wired protocol, which is preferably transmitted via a data bus system, from the central control unit 120, which are addressed to specific devices 20 (in the wired protocol), in order to then forward them to these devices 20 via radio.

[0062] The control unit 120 can exchange data D with the building technology element 10 via the system communication interface 110. Data D from the system 200 is received from wirelessly connected devices 20 by the building technology element 10 via the system communication interface 110. Furthermore, it is possible to exchange data D between the building technology elements 10, wherein the building technology element 10 can transmit the data D from the system 200 to other building technology elements 10, as shown in simplified form in Fig. 1 and Fig. 2.

[0063] Likewise, data D can be transmitted via the system communication interface 110 or via the communication interface 16 of the further building technology elements 10 to the building technology element 10 for controlling a device 20 of the system 200.

[0064] For example, operating parameters of a device 20 such as a luminaire 20 can be forwarded to the control unit 120 or another motion and / or presence detector 10 by means of the building technology element 10 according to the invention, for example the motion and / or presence detector 10 described above. As already described, the wireless protocol (for example Bluetooth Mesh) is converted into a wired protocol (for example KNX). This is shown in simplified form in Fig. 2, wherein the luminaire 20 and the motion and / or presence detector 10 are located in the room R1. Likewise, the motion and / or presence detector 10 can transmit operating parameters of a another device 20, such as a heater 20, located in another room R2. The building control system 100 can be a KNX bus system.

[0065] This concept is also suitable for commercial or office buildings. For example, not all rooms would have to be designed with a KNX bus control system. Stairwells, corridors, ancillary rooms, and restrooms can be equipped with Bluetooth products, eliminating the need for more expensive KNX installations with wired communication lines. This results in less cable load and fewer building technology elements 10 are required. Bluetooth luminaires 20 can wirelessly transmit data D such as brightness and luminaire status (on / off, dimming level) to the motion and / or presence detectors 10 installed in the offices, which are integrated into the KNX bus. These can then translate the data D into a corresponding KNX protocol using their processing units 18 with the software-based gateway functionality described above.Furthermore, the motion and / or presence detectors can also forward their own data, for example, the presence of people, along with the processed data D from the Bluetooth lights 20 to the control unit 120. Control commands from the control unit 120 (for example, a central OFF in the evening in the office building) can also be transmitted to these Bluetooth products via the motion and / or presence detectors 10, since they support both communication media.

[0066] In another example, corresponding Bluetooth luminaires 20 can also be arranged outside the building G, which can exchange data D with a motion and / or presence detector 10 mounted on an exterior wall of the building G, which is illustrated in simplified form in Fig. 2. Similar to the above example, the Bluetooth luminaires 20 can be integrated into the building control system 100 without complex KNX installation. Individually switching luminaires 20 via the KNX bus would result in very high cabling costs.Here, the embodiment of the invention, providing a mesh radio network of devices 20 as a system 200, has the great advantage that the range can be extended as desired through appropriate hops or forwarding processes in the mesh radio network, provided that the mesh radio network is dense enough so that a device 20 is always in radio contact with at least one other device 20. Thus, a solar light in an area of ​​a large garden remote from the house can be controlled using KNX. The KNX commands are transmitted from the central control unit 120 to the building technology element 10 and then, via multiple jumps or hops across multiple devices 20 of the system 200, finally to the addressed device 20. This is also possible because the amount of data to be transmitted / the required bandwidth is not limiting for this application.

[0067] This integration of the devices 20 via the building technology element 10 can save costs due to the reduced cabling effort. Installation effort is also reduced, since the pure supply voltage of Bluetooth products is sufficient without additional bus cables.

[0068] Fig. 3 shows a flowchart of an embodiment of a method 300 for controlling a device 20 in a system 200 of wirelessly communicating devices 20 according to the present invention.

[0069] In step S310, a radio interface 24 of the device 20 is connected to the radio interface 14 of the building technology element 10 described above in the building control system 100 for exchanging data D.

[0070] In step S320, data D is received from the building technology element 10 of the building control system 100 via the radio interface 24 of the device 20. The data D may include control signals for controlling the device 20.

[0071] The device 20, for example, the lamp 20 described above, can perform a corresponding control such as on / off based on the control signals. No additional actuator is required for this purpose.

[0072] Furthermore, a computer program is provided which comprises instructions which, when executed by a device 20 of a system 200 comprising wirelessly interconnected devices 20, cause the device 20 to execute the method 300 described above.

[0073] Also provided is a computer-readable medium comprising instructions that, when executed by a device 20 of a system 200 of wirelessly interconnected devices 20, cause the device 20 to perform the method described above.

[0074] Furthermore, a data processing device is provided which comprises means for carrying out the method 300 described above.

[0075] By means of the building technology element 12 according to the invention, the building control system 100, and the method 300, KNX products do not need to be installed at all locations in or around the building G. The building technology element 10 makes it possible to provide information from "non-KNX products" (for example, presence, brightness values, status of luminaires 20, dimming level, or other sensor values ​​such as temperature or air) in the KNX bus system, or to send control signals (for example, switching off, switching on, dimming) from the KNX bus system to the "non-KNX products."

[0076] The present invention expands the limited use of the Bluetooth interface in the field of KNX products. Currently, it is used only to display KNX product values ​​and to start KNX programming mode. The KNX products are extended by a software-based gateway that enables communication from the Bluetooth or Bluetooth Mesh environment to the KNX environment and vice versa. Commands and settings from the KNX bus system can be transferred to the Bluetooth products and groups.

[0077] The integration of the gateway functionality between the KNX protocol and the Bluetooth protocol in motion and / or presence detectors allows information to be transferred between the protocols without additional hardware (classic gateways).
