ELECTRICAL INSTALLATION DEVICE FOR CONTROLLING AN ELECTRICAL APPLIANCE

Description

[0001] The invention relates to an electrical installation device for controlling an electrical consumer. The electrical installation device comprises a power module, at least one functional module, and at least one operating module.

[0002] The power module has electrical contacts for contacting a voltage source, at least one mounting means for mounting on a wall, in particular in an installation opening, and at least one holding means for releasably fastening the functional module.

[0003] In the sense of the invention, the installation opening can be designed both for flush-mounted installation in a wall and for surface-mounted installation in a device box that can be mounted on the wall.

[0004] The functional module has a functional control unit for determining a processing process for an operating signal for generating the control signal and at least one holding means for releasably fastening to the power module.

[0005] The operating module has an operating element for generating the operating signal and a holding means for releasably fastening the operating module to the power module or the function module.

[0006] Electrical installation devices for controlling a consumer are particularly common in home communication technology and are frequently used as control elements for lighting devices, such as room lamps or window shutters. These control elements are usually designed as switches, push buttons, or dimmers.

[0007] In order to keep manufacturing costs low and to maximize the assembly and application possibilities of electrical installation devices depending on the control type and the loads to be controlled, there is a need to design electrical installation devices at least partially in a modular manner. This is demonstrated by way of example in document DE 201 22 102 U1.

[0008] Furthermore, a room redesign may result in a new design direction, meaning that the original electrical installation devices no longer fit the desired appearance or no longer fulfill certain functions, such as illuminated switches or other safety aspects, even when considering barrier-free living. In this context, conversions for senior-friendly living are particularly worth mentioning. It is known from the state of the art to provide installation boxes or special installation openings that can be surface- and / or flush-mounted and into which an electrical installation device can be inserted. The installation openings usually have a standardized size so that a variety of electrical installation devices can be inserted into the installation opening.The installation openings for electrical installation devices are usually designed with a height of 55 mm and a width of 55 mm, whereby the depth of the electrical installation devices can vary in one installation direction.

[0009] Due to different country-specific power grids, e.g., 110 V or 220 V voltage grids, as well as different communication networks for building services, such as the use of EIB / KNX, Ethernet, Powerline, 868 MHz radio, Bluetooth, WLAN, and other communication standards, known electrical installation devices are limited to specific regions and / or communication networks. For the purposes of the invention, all of these networks are summarized under the term "building network."

[0010] To adapt the function or operation, either functionally or structurally, state-of-the-art electrical installation devices are regularly completely replaced. It is also common practice to replace, for example, a rocker switch or a mounting frame with a new appearance to adapt the electrical installation device to a new design.

[0011] With conventional electrical installation devices, adaptability is therefore limited only by replacing the entire device or by replacing design elements that do not significantly change the function, thus severely restricting variability. As a result, the manufacturer and the end user must commit to a specific type of operation and communication or networking. For example, with an electrical installation device designed as a dimmer, the user has the choice between a mechanical button, a rotary knob, or a so-called "touch dimmer" with a touch-sensitive surface. Subsequent changes, e.g., from a mechanical button to a rotary knob, are usually only possible by replacing the entire electrical installation device. A similar problem arises with conventional electrical installation devices when the house network is replaced, e.g., with a new electrical system.due to relocation, and the electrical installation equipment should continue to be used.

[0012] The invention is based on the object of providing an electrical installation device which can be more easily adapted or modified in terms of function, networking and / or operation and / or design.

[0013] The object is achieved according to the invention by an electrical installation device having the features of claim 1.

[0014] The electrical installation device has at least three modules, a power module, a function module and an operating module, each of which is designed as a self-contained housing unit and together forms the electrical installation device.

[0015] "Contained housing unit" in the context of the invention means that the modules each have their own housing, with at least the functional module and the operating module being designed as attachments, so that the modules, with all associated components, can be separated and assembled as a unit. The modules are connected to one another by means of the retaining means, in particular mechanically and / or magnetically, in a detachable manner without damage. The power module expediently forms a base onto which the functional module and the operating module can be mounted as attachments.

[0016] In particular, the individual modules are each interchangeable with generic modules of their type, so that a first operating module, e.g. for operating a dimmer with mechanical push buttons, can be replaced by a generic second operating module, e.g. for operating a dimmer with a mechanical rotary knob, independently of the power module or the function module.

[0017] In the sense of the invention, "generic module" describes the three types of modules: power module, function module and operating module.

[0018] The category of operating modules encompasses various operating technologies, which can be located directly on the operating module or via a communication interface that enables operation via another remote device. For illustration, this category includes, for example, a mechanical button or switch, a mechanical rotary knob, touch-sensitive, particularly electrostatic, surfaces, and capacitive control panels, in which an electric field is changed by approach or touch, so that a gesture or touch can be detected. Other operating modules include, for example, other optical, thermal, or acoustic sensors, as well as radio receivers or IR receivers.

[0019] Corresponding to the operating module, the power module and the function module are also interchangeable with generic counterparts, generic function modules or generic power modules.

[0020] For example, generic power modules can differ in the level of the supply voltage, in particular 110V or 220V, and / or in the type of connection technology, in particular 2-wire or 3-wire connection, or the communication connection, e.g. KNX / EIB bus connection.

[0021] Generic function modules preferably differ in the way in which an operating signal is to be processed; in particular, an operating module can also simply refer to a specific processing step, which is stored in particular in the power module, with the actual processing step also being carried out in the power module. In this case, the function module serves as a function indicator for the power module. Furthermore, generic function modules can differ in their switching and / or control logic; in particular, in such a case the function control unit is designed such that it can process the operating signal and generate the control signal. Such switching and / or control logic is, for example, a simple on / off switch, a changeover switch, a cross switch, a dimming function, a roller shutter control, a valve control and the like.

[0022] This means that the user can customize his electrical installation device, choosing from a modular system with regard to the power module, the function module and the operating module, in order to put together the optimal electrical installation device that meets his needs.

[0023] In particular, the control signals in the function module are generated by the function control unit and can be routed to the power module and from the power module to a building network. Alternatively, the power module has a control unit connected to the function control unit of the function module, wherein the control unit can process the operating signal and generate the control signal depending on the function control unit. These designs make it possible to arrange switching elements or other processing devices that respond to the control signals outside the electrical installation device. For example, the control signals can be processed for a bus system and routed to the building network.According to a particularly advantageous embodiment, the power module therefore has electrical contacts for contacting a BUS line and a bus controller for communication via the BUS line and for transmitting a BUS control signal for controlling the electrical consumer via the BUS line.

[0024] Advantageously, especially if there is no BUS network or an electrical load to be switched is not connected to the BUS network, the power module can have electrical contacts for contacting the electrical load and / or electrical switching means for directly switching the electrical load.

[0025] In particular, in order to combine the power module, the function module, and the operating module into a single unit, the function module can each have a holding means for connecting to the power module and for connecting to the operating module. This design is particularly advantageous in a further variant of the electrical installation device, according to which the function module is arranged between the power module and the operating module in the mounting direction, and a function module interface of the power module is connectable to a power module interface of the function module, and an operating module interface of the function module is connectable to a function module interface of the operating module. In particular, by arranging the modules in the mounting direction, the surface area of ​​the operating module can be enlarged, which can be advantageous for ease of use or for positioning the at least one operating element.Furthermore, the functional module is better protected against external influences and the appearance of the electrical installation device is improved.

[0026] Alternatively, it may be advantageous if the functional module and the operating module can be arranged side by side on the power module in a common plane in the mounting direction, or are arranged in an assembled state. In particular, the respective modules are easily accessible in this design, and assembly and / or disassembly can be carried out more easily.

[0027] The power module can expediently transmit a supply voltage to the function module and / or the control module. In particular, the power module has power supply electronics that can convert a mains voltage or bus voltage of the building's network into a DC voltage as the supply voltage for the electronic components of the power module, the function module, and / or the control module.

[0028] The functional module is expediently designed to enable a functionality integrated or stored in the power module. This functionality is, in particular, the processing of the operating signal. For this purpose, a device identifier / ID tag is contained in the function control unit, or the device identifier / ID tag can be read from a memory via the function control unit.

[0029] The device identifier / ID tag is, in particular, a transponder component of an RFID system that functions as an identifier. The transponder can be conveniently supplied with power from a neighboring module and then read. The power supply is preferably inductive and contactless. Optionally, the device identifier / ID tag can have electronic encryption and / or an electronic signature for security purposes. Alternatively or additionally, the device identifier / ID tag is designed to enable authenticity verification. The authenticity verification is useful for proving the authenticity and forgery-proof nature of the functional module. The functionality integrated or stored in the power module is advantageously adapted or provided depending on the detected transponder.

[0030] Advantageously, the function module provides the device identifier / ID tag via the function control unit, which is detected by a reading unit formed in the power module. The device identifier / ID tag can expediently be transmitted via the power module interface of the function module and the function module interface of the power module. In particular, the power module can provide the respective integrated or stored functionality or execute the processing for the operating signal based on the device identifier / ID tag provided by the function control unit. Based on the device identifier / ID tag, the power module thus both generates the control signal and expediently contacts the electrical load depending on the control signal.The function module is thus decoupled from functional components and uses the device identifier / ID tag to determine the settings for the processing to be executed for the control signal. For example, the device identifier / ID tag can be identified by the function module as a "blind control," whereupon the function module provides the "slat adjustment" functionality, which it would not offer with a device identifier / ID tag for a "light control."

[0031] According to one embodiment, the functional module has switching elements that are connected at least to the electrical contacts of the power module. The switching elements are expediently controllable by the control signal of the functional control unit of the functional module. Advantageously, according to this embodiment, by replacing the functional module with a different functional module of the same type, the electrical installation device or the desired effect of the electrical installation device can be extensively modified, since the power module merely establishes the connection to the house network, with the functional module itself providing the interconnection and / or switching signals in response to the operating signal or the control signal.

[0032] According to one variant, the power module has switching elements. In particular, the switching elements of the power module are connected to the electrical contacts of the power module. Advantageously, the switching elements are controllable by means of the control signal of the function control unit, wherein the control signal can be transmitted to the switching elements in the power module.

[0033] In particular, the supply voltage makes it possible to supply the functional module, in particular the functional control unit of the functional module, and / or the operating element of the operating module with an electrical voltage.

[0034] In particular, touch-sensitive screens, wireless network interfaces or illuminated buttons can be easily supplied with the necessary voltage.

[0035] In particular, a functional module interface of the power module is electrically connectable or connected to a power module interface of the functional module, and preferably an operating module interface of the power module is electrically connectable or connected to a power module interface of the operating module. In this embodiment, it is expediently possible to transmit the operating signal from the operating module to the power module via the power module interface of the operating module and the operating module interface of the power module, and to the functional module via the functional module interface of the power module and the power module interface of the functional module.In particular, this embodiment further provides that the control signal can be transmitted to the power module via the power module interface of the functional module and the functional module interface of the power module, so that the power module can contact and / or connect the consumer directly and / or indirectly in response to the control signal.

[0036] Advantageously, the supply voltage can be applied from the power module to the operating module via the operating module interface of the power module, to the operating module via the power module interface of the operating module and / or to the function module via the function module interface of the power module and the power module interface of the function module.

[0037] According to an advantageous embodiment, a functional module interface of the power module is electrically connectable or connected to a power module interface of the functional module, and an operating module interface of the functional module is electrically connectable or connected to a functional module interface of the operating module. Advantageously, the operating signal from the operating module can be transmitted via the functional module interface of the operating module and the operating module interface of the functional module. Preferably, the control signal from the functional module can be transmitted to the power module via the power module interface of the functional module and the functional module interface of the power module.

[0038] In particular, the supply voltage can be transmitted from the power module to the functional module via the functional module interface of the power module and the power module interface of the functional module. Furthermore, the supply voltage can preferably be transmitted from the functional module to the operating module via the functional module interface of the operating module.

[0039] Another embodiment provides that a functional module interface of the power module is electrically connectable or connected to a power module interface of the functional module and an operating module interface of the power module is electrically connectable or connected to a power module interface of the operating module and a functional module interface of the operating module is electrically connectable or connected to an operating module interface of the functional module.

[0040] Advantageously, the operating signal can be transmitted from the operating module to the functional module via the functional module interface of the operating module and the operating module interface of the functional module and / or to the power module via the power module interface of the operating module and the operating module interface of the power module, and from the power module to the functional module via the functional module interface of the power module and the power module interface of the functional module.

[0041] It is expedient for the supply voltage to be applied from the power module to the operating module via the operating module interface of the power module and the power module interface of the operating module and to the function module via the function module interface of the power module and the power module interface of the function module.

[0042] Alternatively or additionally, the supply voltage can also be transmitted from the power module to the operating module or the function module via the operating module interface of the power module or the function module interface of the power module and the power module interface of the operating module or the power module interface of the function module and transmitted from the operating module or the function module to the function module or the operating module via the function module interface of the operating module and the operating module interface of the function module.

[0043] In particular, the power module and / or the function module and / or the operating module are connected in series or parallel to each other for connection to the supply voltage.

[0044] At least the function module interface and / or the power module interface and / or the operating module interface are expediently designed as electrical plug contacts, as a contactless inductive interface or radio-based interface, wherein the power module interface or the operating module interface or the function module interface to be connected is expediently designed correspondingly.

[0045] As a supplement or alternative, it has also been found that advantageously at least the power module interface and / or the operating module interface and / or the function module interface are designed as first induction interfaces, wherein in particular the power module interface to be connected to the first induction interface or the operating module interface or the function module interface is designed correspondingly as a second induction interface.

[0046] According to one variant of the electrical installation device, the power module and / or the operating module and / or the function module has an RFID chip. In particular, at least one device identifier of the respective power module or operating module can be read from the RFID chip. The RFID chip can expediently provide a device identifier / ID tag of the function module, in particular to the power module, for determining the processing method for the operating signal, wherein the RFID chip is designed as part of the function control unit or is directly connected to the function control unit. Furthermore, it has proven advantageous if at least one RFID reading unit is designed in the power module and / or the function module and / or the operating module. The device identifier is advantageously used for the automatic configuration of the power module, the function module and / or the operating module.

[0047] The RFID chip, in particular, is particularly advantageous for preventing installation errors. This increases the lifespan of the electrical installation device and ensures its functionality.

[0048] The electrical installation device expediently comprises at least one microcontroller, which is particularly designed as part of the function control unit or is connected to the function control unit. Advantageously, the microcontroller is integrated in the power module and / or the function module.

[0049] Preferably, the RFID reading unit(s) in the power module and / or the functional module and / or the operating module is / are connected to the microcontroller in such a way that at least the device identifier can be recognized and processed by the microcontroller.

[0050] Advantageously, the function module and / or the power module and / or the operating module, preferably the function module and / or the power module, can recognize the respective other modules by means of the microcontroller and configure themselves accordingly so that the respective function is fulfilled. The power module expediently has the control unit connected to the function control unit of the function module. The control unit can be connected to the function control unit in particular via the module interfaces and / or an RFID connection. Advantageously, the control unit has the microcontroller for processing the device identifier / ID tag. The control unit can process the operating signal and generate the control signal depending on the device identifier / ID tag of the function control unit of the function module.

[0051] In particular, the function control unit can evaluate the operating signal according to the operating module and forward an adapted control signal according to the power module. Furthermore, the power module can provide a supply voltage to the respective modules according to the operating module identified by the device identifier and / or the function module identified by the device identifier.

[0052] A memory is expediently connected to the microcontroller, which the functional module and / or the power module has. The microcontroller is connected to the functional control unit. Alternatively, the microcontroller itself forms the functional control unit in whole or in part. Preferably, at least one control process for processing at least one operating signal and generating at least one specific control signal and / or for providing at least one specific supply voltage is stored in the memory.

[0053] Preferably, the memory stores control processes, in particular processing processes, adapted to different power modules and / or operating modules and / or functional modules for processing different operating signals and / or generating different control signals and / or providing different specific supply voltages. In particular, this allows the modules to be used in different combinations, so that the respective modules can be easily interchanged with similar modules.

Furthermore, the control element can also be designed as a receiver, e.g., an infrared receiver, an RFID receiver, or a radio receiver, so that a user can actively send a command to the control element to thereby generate the desired effect of the electrical installation device. The control element can also be configured to receive multiple commands from a receiver, so that, for example, a multi-button remote control can send different commands to the receiver, e.g.,Light on / off and roller shutter up / down, whereby the operating module outputs a different operating signal for each command, which the function control unit in the function module or the control unit in the power module, in particular according to an advantageous embodiment by means of the microcontroller, assigns to the corresponding control process.

[0063] Fig. 1 and 2 show an electrical installation device 1 for controlling an electrical consumer. This device has a power module 100, at least one function module 200, and at least one operating module 300.

[0064] Electrical installation devices 1 for controlling a consumer are designed in particular as switches for lighting devices, e.g. for room lamps, or e.g. as roller shutter controls, as push buttons or dimmers.

[0065] The power module 100 has, as shown in Fig. 3 to 6 shown, electrical contacts for contacting a voltage source, at least one mounting means for mounting on a wall, in particular in an installation opening, and at least one holding means for releasably fastening the functional module 200.

[0066] Particularly advantageously, the electrical contacts of the power module 100 are designed as gold contacts and / or spring contacts, e.g., Pogo line of the ECT brand.

[0070] Furthermore, the functional module 200, the operating module 300 and the power module 100 are each designed as a self-contained housing unit.

[0071] "Sealed housing unit" in the sense of the invention means that the modules 100, 200, 300 each have their own housing, as shown schematically in the Fig.1 and 2 is shown, wherein at least the power module 100 and the operating module 300 are attachments, so that the modules 100, 200, 300 with all associated components can be separated from one another and assembled as a unit, wherein the modules 100, 200, 300 are detachably connected to one another by means of the holding means.

[0072] The electrical installation device 1 is preferably mounted in a mounting opening. These mounting openings can also be formed in mounting boxes. Furthermore, the mounting openings can be designed for surface-mounted or flush-mounted installation.

[0073] The installation openings preferably have a standardized size so that different types of electrical installation devices 1 can be inserted into the installation opening.

[0074] In particular, the installation openings for the electrical installation device 1 are designed with a height of 55 mm and a width of 55 mm, wherein the depth of the electrical installation device 1 or the installation opening can vary in a mounting direction M.

[0075] Advantageously, the individual modules 100, 200, 300 are each interchangeable by generic modules 100, 200, 300 of their type, so that each module 100, 200, 300 can be replaced by another generic module 100, 200, 300.

[0076] "Generic module" in the sense of the invention describes the three module types: power module 100, function module 200 and operating module 300.

[0077] In a first embodiment, the function control unit FS is advantageously designed such that it can process the operating signal BS and generate the control signal SS. The control signal SS can be transmitted from the function module to the power module via module interfaces 102, 104, 202, 204, 302, 304.

[0078] According to a further advantageous embodiment, the power module 100 has a control unit connected to the function control unit FS of the function module 200. This connection can be established via the module interfaces 102, 104, 202, 204, 302, 304, as described above. The control unit is expediently designed such that, depending on the function control unit FS, it can process the operating signal BS and generate the control signal SS.

[0079] For this purpose, the functional module 200 is expediently designed such that it enables a functionality integrated or stored in the power module 100. This functionality is, in particular, the processing of the operating signal BS. For this purpose, a device identifier / ID tag is contained in the function control unit FS, or the device identifier / ID tag can be read from a memory via the function control unit FS. Advantageously, the functional module 200 provides the device identifier / ID tag via the function control unit FS, which is detected by a reading unit formed in the power module 100. The device identifier / ID tag can expediently be transmitted via the module interfaces 102, 104, 202, 204, 302, 304, in particular a power module interface 202 of the functional module 200 and a function module interface 102 of the power module 100.

[0080] Advantageously, the power module 100 can provide the respective integrated or stored functionality or execute the processing for the operating signal BS based on the device identifier / ID tag provided by the function control unit FS. Based on the device identifier / ID tag, the control signal SS is generated in the power module 100 and the electrical load is expediently contacted depending on the control signal SS. The function module 200 is thus decoupled from functional components and uses the device identifier / ID tag to determine the setting for the processing to be executed for the operating signal BS.

[0081] According to an embodiment not shown, the power module 100 has electrical contacts for contacting a BUS line. Preferably, the power module 100 or the function module 200, in particular the function control unit FS, has a bus controller for communication via the BUS line and for transmitting a BUS control signal for controlling the electrical load via the BUS line. In particular, the control signals SS can be processed by the bus controller into BUS control signals, wherein the BUS control signals are either transmitted directly from the power module to the BUS line or, alternatively, the BUS control signals are first transmitted to the power module 100 and then via the electrical contacts to the BUS line. This embodiment makes it possible to arrange switching elements or other processing devices that respond to the BUS control signals outside the electrical installation device 1.

[0082] Furthermore, according to a preferred embodiment (also not shown), the power module 100 has electrical contacts for contacting the electrical load and electrical switching means for directly switching the electrical load. This embodiment can both supplement the electrical contacts for contacting the bus line and represent an alternative embodiment, particularly when no bus lines are in contact with the power module 100.

[0083] In particular, the power module 100 is configured for connection to known home networks, such as 110V or 220V, current or voltage networks, with in particular 2-wire or 3-wire connections, or e.g. KNX / EIB bus connections.

[0084] Advantageously, the functional module 200 has a holding means for connecting to the power module 100 and for connecting to the operating module 300. This embodiment is particularly advantageous when the respective modules 100, 200, 300 are arranged relative to one another as shown in Fig. 2 In this arrangement according to Fig. 3 The functional module 200 is arranged in the mounting direction M between the power module 100 and the operating module 300. The functional module 200 expediently has holding means for the operating module 300 pointing against the mounting direction M, as well as for the power module 100 pointing in the mounting direction M.

[0085] An advantageous interconnection of the modules 100, 200, 300 to one another consists in that the functional module 200 is arranged in the assembly direction M between the power module 100 and the operating module 300. Advantageously, the functional module interface 102 of the power module 100 is connectable or connected to the power module interface 202 of the functional module 200, and an operating module interface 204 of the functional module 200 is connectable or connected to a functional module interface 304 of the operating module 300. Such connections of the respective interfaces to one another are shown in Fig. 5 In particular, the modules 100, 200, 300 are shown in the arrangements of the modules 100, 200, 300 as shown in the Fig. 1 and 2 are shown, preferably Fig. 2 , can be connected in this way.

[0086] Another module arrangement is in Fig. 1 shown.

[0106] In particular, the power module 100, the function module 200, and the control module 300 can be connected in series to supply the supply voltage. Alternatively, the function module 200 and the control module 300 can be connected in parallel with the power module 100.

[0107] According to an embodiment not shown, the power module 100 and / or the operating module 300 and / or the functional module 200 preferably have an RFID chip. Expediently, at least one device identifier of the respective power module 100 or operating module 300 or functional module 200 can be read from the RFID chip. Preferably, the RFID chip can provide a device identifier / ID tag of the functional module 200, in particular to the power module 100, for determining the processing method for the operating signal BS, wherein the RFID chip is advantageously designed as an RFID chip as part of the function control unit FS or is expediently connected directly to the function control unit FS. Furthermore, at least one RFID reading unit is advantageously designed in the power module 100 and / or the functional module 200 and / or the operating module 300.

[0108] In particular, the electrical installation device 1 comprises a microcontroller (not shown) that is connected to the function control unit FS or itself forms the function control unit FS in whole or in part. The microcontroller expediently evaluates the device identifier and is capable of setting, in particular independently, certain parameters relating to the control signal SS and the operating signal BS and / or the supply voltage of the modules 100, 200, 300 based on the device identifier.

[0109] The power module 100 expediently includes the control unit connected to the function control unit FS of the function module 200. The control unit can be connected to the function control unit FS, in particular, via the module interfaces and / or an RFID connection. Advantageously, the control unit includes the microcontroller for processing the device identifier / ID, so that the control unit can process the operating signal BS and generate the control signal SS depending on the function control unit FS.

[0110] Advantageously, the functional module 200 with the RFID reader, in particular by means of the microcontroller, can recognize the power module 100 and / or the operating module 300, evaluate the operating signal BS adapted according to the operating module 300, and further process it adapted according to the power module 100. Furthermore, it can adapt or control the supply voltage to the connected modules 100, 200, 300 as needed. In particular, this eliminates the need to train the respective modules 100, 200, 300 and facilitates installation and commissioning, especially for untrained users. An advantageous further development of the electrical installation device 1 is characterized in that the functional module 200 and / or the power module 100 has the microcontroller. The microcontroller is preferably connected to a memory on the one hand.Conveniently, the microcontroller is connected to the function control unit FS or itself forms the function control unit FS in whole or in part. Preferably, at least one control process, in particular a processing process for processing at least one operating signal BS and generating at least one specific control signal SS and / or for providing at least one specific supply voltage, is stored in the memory.

[0111] The memory expediently stores control processes adapted to different power modules 100 and / or operating modules 300, in particular processing processes for processing different operating signals BS and / or for generating different control signals SS and / or for providing different special supply voltages. This embodiment has the special feature that a function module 200 can be used or adapted in different combinations of power modules 100 and / or operating modules 300. The advantage is, among other things, that the function module 200 itself can be used in different electrical installation devices 1, or the power module 100 and / or the operating module 300 can be replaced while maintaining the intended function of the new power module 100 and / or the new operating module 300.

[0112] According to a preferred embodiment not shown, the functional module 200 and / or the power module 100 and / or the operating module 300 has a maintenance interface connected to the microcontroller for connection to an external read / write unit. Particularly advantageously, the read / write unit is designed and connectable to the microcontroller via the maintenance interface in such a way that the read / write unit can process and / or supplement the control processes stored in the memory. In particular, control processes can be modified and supplemented using the maintenance interface. Furthermore, the software of the functional module 200 can be updated, in particular to correct software errors, improve the functions of the control processes, and / or eliminate security gaps.

[0113] According to one embodiment, only the memory can be read via the maintenance interface. This variant is advantageous, for example, for checking the compatibility of the function module 200 with other power modules 100 or operating modules 300, for example, using the stored control processes.

[0114] In a variant not shown, the operating module 300 preferably has more than one operating element 306. The operating module 300 is expediently designed such that upon actuation of the different operating elements 306, the operating elements 306 each generate their own operating signal BS, which can be sent to the functional module 200 and / or the power module 100.

[0115] In particular, the function control unit FS or the control unit of the power module 100 is designed such that it can distinguish between the operating signals BS of the respective operating elements 306.

[0116] For example, such an operating module 300 can be designed in the form of at least two rocker switches, e.g., in a stairwell, with each rocker switch representing an operating element 306. Such an operating module 300 can also be a doorbell unit with multiple bell buttons, with each bell button corresponding to an operating element 306.

[0117] Fig. 1 and 2 show an advantageous embodiment characterized in that the operating element 306 of the operating module 300 can be actively operated by a user. Preferably, the operating module 300 can send at least one operating signal BS to the functional module 200 or the power module 100 in response to the operation, or sends at least one operating signal BS to the functional module 200 or the power module 100 in response to the operation.

[0118] In particular, an actively operable control element 306 is understood to be a control element 306 that the user consciously decides to operate or must perform an action. This can be, for example, a push-button switch or a rotary control, such as a dimmer, or a radio receiver.

[0119] Furthermore, the operating element 306 is preferably pressure-sensitive, e.g., as shown in the Fig. 1 and 2shown, designed as a push button, a rocker switch, or a touch-sensitive display surface, or is expediently designed as a receiver, e.g., as an infrared receiver, an RFID receiver, or a radio receiver. The embodiment of the operating element 306 as a receiver is not shown. In particular, a receiver is connected to the function control unit FS or the control unit of the power module, wherein the operating signal BS is transmitted in the form of the received data to the function control unit FS or the control unit of the power module 100, where it is evaluated and processed into a control signal SS. This occurs, in particular, by means of the microprocessor.

[0120] In an alternative embodiment, the operating element 306 is designed as an environmental sensor. Particularly advantageously, the environmental sensor is designed as a thermometer, a light sensor, or a motion sensor, whereby the selection of possible sensors is not limited to those mentioned.

[0121] In particular, electrical installation devices 1 that have more than one operating element 306 or operating module 300 can have different types of operating elements 306; in particular, the selection of operating elements 306 is not limited to the aforementioned types of operating elements 306—pressure-sensitive operating element 306, receiver, environmental sensor. In particular, the functional module 200 or the control unit of the power module 100 can also link certain control signals SS to a combination of operating signals BS, in particular of different operating elements 306 or operating modules 300, so that, for example, the synchronous actuation of two operating elements 306 generates a different control signal SS than the actuation of the respective operating elements 306 individually, or that, for example, an actively actuated operating element 306 generates different control signals SS depending on the measurement data of an environmental sensor.In particular, two- or multi-factor authentication can be provided by processing at least two operating signals BS. For example, a first operating signal BS is generated by a correct code entry, while a second operating signal BS is generated by an RFID query. In particular, the two operating signals BS are processed in the function control unit FS or the control unit of the power module 100, in particular by means of the microcontroller, and a control process is triggered. In this sense, a first operating element 306 can also be expediently designed as an active operating element 306, for example, a button for selecting a floor in an elevator, and a second operating element 306 can be designed as a smoke detection sensor, so that, for example, in the event of a fire, floor selection or elevator use is no longer possible.

[0122] The holding means are expediently designed at least partially as a mechanical and / or magnetic holding means. In In an advantageous variant, the holding means are at least partially designed as a detachable screw connection. In particular, each holding means is assigned a counter-holding means on the module 100, 200, 300 to be fastened. For example, the holding means designed as a screw connection is assigned a counter-holding means, wherein the counter-holding means is designed to correspond to the holding means, so that at least the holding means is designed as a screw and the counter-holding means as a screw receptacle.

[0123] It is also expedient if the holding means are at least partially designed as clamping or locking means. Preferably, a counter-holding means is designed to correspond to the holding means, in particular such that at least one holding means is designed as a locking or clamping arm and the counter-holding means is designed to correspond to the locking or clamping arm receptacle.

[0124] The housing units of the modules can expediently have a contour adapted to the type, so that, for example, all control modules 300 have the same external shape, all function modules 200 have the same external shape, and all power modules 100 have the same external shape. In particular, this design supports the easy replacement of modules 100, 200, and 300 of the same type and ensures sufficient installation space in the electrical installation device 1 without remeasurements.

[0125] The operating module 300 and / or the function module 200 and / or the power module 100 can expediently have a mounting coding that indicates the mounting direction M or the relative installation position of the respective module 100, 200, 300 to the electrical installation device 1 or to the other modules 100, 200, 300. This simplifies installation and prevents errors.

[0126] Advantageously, the preferably magnetic holding means and counter-holding means are arranged on the respective modules in such a way that fastening is only achieved when positioned correctly. This can be achieved, for example, by selecting the polarity of the magnetic holding means and counter-holding means, so that the desired attraction occurs between the respective holding means and the counter-holding means when positioned correctly, and repulsion occurs when attempting to mount the modules incorrectly. This advantageously provides a symmetrical structure of the modules while maintaining a high level of installation reliability.

[0127] In particular, the housing unit of the operating module 300 and / or the functional module 200 and / or the power module 100 has an external shape with a mounting contour, so that the respective modules 100, 200, 300 can only be mounted in a designated installation position, and deviating installation positions are prevented, in particular by a positive locking mechanism. All housing units of a module type expediently have the same mounting contour to ensure uncomplicated replacement or reassembly.

[0128] Mounting means within the meaning of the invention can advantageously be mechanical and / or magnetic. In particular, the mounting means can be designed as a screw connection or a claw arrangement for wedging the power module 100 into the installation opening.

[0129] The invention is not limited to the illustrated and described embodiments, but also encompasses all equivalent embodiments within the meaning of the invention. It is expressly emphasized that the embodiments are not limited to all features in combination; rather, each individual partial feature can also have an inventive significance in itself, independently of all other partial features. Furthermore, the invention is not yet limited to the combination of features defined in claim 1, but can also be defined by any other combination of specific features of all the individual features disclosed as a whole. This means that, in principle, practically every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application.
