Description

HOME AUTOMATION SYSTEM AND HOME DEVICE SWITCHING DEVICE WITH A BUTTON UNIT

The invention relates to a home automation and / or home information system with a central unit for operating a plurality of home automation functional units. In particular, lamps, blinds, heaters, in particular radiator valves, ventilators, window opening and closing devices, ventilation devices and the like are considered as domestic engineering functional units.

Skin automation and home information systems are known from the prior art, wherein traditionally the various home automation functional units can be wired or wirelessly controlled via a central processing unit. In this case, for example, via the individual home automation functional units, in particular via functional sockets, connected to the power network of the building switches, contact switches, motion detectors and other sensors send information signals to the central unit, which in turn on the same or on corresponding building services function units controlling or . acting regulatively. Specifically, the information transfer bound via the switch units is conventionally usually bound to the power supply or to the electrical lines in the building or at least bound to the switchboard mounting sockets or socket outlets provided for this purpose in the building walls. Thus, a flexible home automation or control of a building can only conditionally perform, since the information-communicating switches are localized. The object of the invention is therefore to provide a home automation and home information system in which the information or the actuation-triggering information is not transmitted to a central unit stationary. The use of the system and the devices used for this purpose should be flexible and reliable from multiple locations feasible. The invention should also solve the task of creating a home automation switching unit that allows a particularly flexible use anywhere on a building. The home automation and home information system should be simple in construction and inexpensive to deploy. The object is achieved by a home automation and home information system according to claim 1, wherein preferred embodiments are specified in the dependent claims of claim 1. The object is further solved for existing home automation and home information systems by a domestic switching device according to claim 9, which can be used in existing systems. Preferred embodiments of the domestic switching device are specified in the dependent of claim 9 dependent claims.

According to the invention, the home automation and home information system has a central unit for actuating a plurality of functional units in a building, wherein according to the invention at least one home automation switching device is provided with a key unit. The key unit includes self-resetting keys, i. the keys are moved from their neutral position to generate a signal in a switching position, from which they automatically move back to the neutral position. Upon actuation of a key, a key-bound signal is transmitted wirelessly from the key unit to a receiver, which forwards this signal to the central unit. The receiver itself may be part of the central unit. The central unit then actuates the key unit associated function unit, as deposited in the central unit.

As functional units are generally all usable in a household or in other buildings devices or facilities that are operable by means of electrical or other energy. These include in particular lighting means of all kinds, heating or cooling devices, shutters or blinds, security systems, consumer electronics, such as audio or television sets, etc.

The key-bound signal emitted by the key unit, which identifies the key actuated, can be freely interpreted by the central unit. For example, the key signal in the central unit can be interpreted as a light on / off signal or as a blind up / down signal. The interpretation of which control signal to be sent by the central processing unit or by a higher-level unit to the functional unit is at the discretion of the architect of the home automation and home information system. As is also conceivable, the key signal in the central unit can also be assigned flexibly to other conditions, such as the location of the key unit, the brightness, the time of day, the power supply costs, the volume, etc., and is not a one-time programming bound. Even changing assignments over the day, week, month or year can be flexibly carried out by the central unit or by a central unit. control unit, such as a PC or a smartphone, or even by a homeowner.

So that a flexible assignment of the functional units to the individual keys of one or more home automation switching device is possible, the individual switching device must be identifiable by the central unit. Thus, using multiple switching devices, each one of these switching devices should have a unique identifier for identification. This is preferably a one-to-one identification code, which is sent by each switching device, in particular when a key of the key unit is actuated. In this case, this identifier is fixed in each switching device or can be changed by the central unit by means of an installation unit or input unit changeable, i. renewable, to be forgiven. Especially upon restarting a home automation and home information system, a variable switch device identification provides a flexible home automation architecture. However, the flexible allocation of the switching device identification facilitates also a possibly necessary expansion of the home automation system, for example when new functional units, receivers or other components are added.

Thus, the home automation system according to the invention with flexible and changeable allocation of identifications for the individual building services switching device and the flexible and modifiable key assignment represents a system that can be adapted to any building situation / equipment that is simple in design, installation and operation ,

According to the invention, each individual home automation switching device at any location, in particular the site, within the transmission range can be arranged to the central unit and is not tied to mounting boxes for light switches or sockets or their recordings. According to the invention, the switching device can be placed on walls or tables or on cabinets as long as the signal emitted by the switching unit remains receivable by the central unit. Includes is also a loose, portable arrangement of the switching unit, which can be taken by the house, for example, in a room change without further notice. The decisive factor is only that the switching unit is not removed from the transmission range to the central unit, since then the signal emitted by the switching unit signal can no longer be received by the central unit.

An inventive home automation system has at least one receiver. Preferably, a receiver is integrated in the central unit and forms a structural unit. To increase the range as well as the approval of additional functions can more

Receiver, for example, via radio or wired to communicate with the central unit in communication. Preferably, the assignment of the functional units to be actuated or a functionality of a functional unit depending on the location of the key unit is festleg bar. An assignment of the functional unit takes place, in particular, depending on which room, in which apartment or in which areas thereof the key unit is located. Thus, for example, the button unit can be guided by the user with him and in the room in which he is currently, with one and the same button of the button unit respectively the light, the blind, the heating or ventilation or the like in each room on the corresponding functional unit controlled. There is also the possibility that at different locations different types of functional units are controlled by one and the same key. It is also possible that functional units are controlled, which are not in the immediate vicinity of the location of the key unit. Here is a great flexibility in the assignment of functional units, since the assignment is always made by the central unit. The location is preferred preference via a determination of the field strength of the key-bound signal at the receiver. To increase the accuracy of the location determination, the central unit may be connected to a plurality of receivers. For example, a receiver may be arranged in each room, in each apartment or in areas thereof. The evaluation of the key-bound signal and in particular the field strength thereof at the receiver is carried out by the central unit. Thus, the central unit can determine the location based on the field strength at more than one receiver, in particular with multiple receivers.

In the evaluation by the central unit, for example, it can be taken into account at which receiver the signal has the greatest field strength or how large the field strength at the individual receivers is relative to one another. Increased resolution and accuracy can be achieved for example by additional information such as the floor plan of the building in which the home automation and home information system is installed, and building-specific features. There is also the possibility that in an initialization process different locations are learned into the system and based on which the location determination or the assignment of the location-dependent functional units takes place.

As an alternative to the position determination via the field strength of the signal, other methods such as, for example, the transit time of the signals to different receivers can also be used. the. Preferably, methods are used in which the home automation system determines the location of the key unit of the home automation, in particular of the central unit. However, methods can also be used in which the key unit determines its location and transmits it via the signal to the central unit. Furthermore, various methods for locating or measuring different variables for determining the location can be combined.

Preferably, the home automation switching device of the home automation and home information system is accommodated in a holder in which it is removably received. Thus, the holder can be fixed in place, for example, on a wall on the floor or on a cabinet or at the same time, the switching unit but also from one point to another is flexible transportable. For example, when leaving the room, the switching unit can be clipped to its wall bracket and leave the room. When re-entering the room, the switching device can be removed from its holder and, for example, be carried to the workplace to operate from there the home automation functional units on the central unit can.

Because of the removable absorbability of the key unit in a holder, a twist protection is preferably provided between the two components, so that the key unit can be used only in one orientation in the holder. Decisive here is that the individual buttons always come to rest at the same position when inserted into the holder stylus unit, and the button unit can not be used twisted.

Preferably, a visible or tactile mark on the stylus unit to make it easy to determine the orientation of the stylus unit in the portable state of the stylus unit. For this purpose, for example, a pin is sufficient to mark the position of a key.

In general, one will document their occupancy for all keys and preferably make a corresponding marking / marking on the key unit itself. Such a marking can be affixed to the button itself or, as is preferred under aesthetic considerations, on the back of the button unit, this marking not being visible when the button unit is inserted in the holder. An identification of the key assignment can also be represented as a function of the current assignment of the key to a functional unit, ie it is displayed on the key which functional unit or which function of a (specific) functional unit is currently actuated upon actuation. Another way of documenting the key assignment of a domestic switching device is their introduction into the holder. The key assignment with button unit is visible or not visible, but it should be visible or palpable with removed key unit. Further preferred is an identification of the key assignment, which is easily recognizable in the dark when the scanner unit is removed from the holder. This can be done, for example, by providing physical markers via the sense of touch or, which is also conceivable, by temporary or permanent illumination of the key itself or key unit. Reflecting areas can also facilitate key recognition in low light conditions.

Preferably, the button unit is designed as a double button with two buttons, which are each assigned two switching positions. So four different signals of the key unit are available for this arrangement, which can be flexibly interpreted by the central unit to operate building services engineering units when a corresponding signal is sent from the button. However, the key unit can be designed as any single or multiple key unit, which is obvious to a person skilled in the art. Regardless of this, it is the task of the central unit to transmit the signal received from the key unit to the corresponding functional unit in such a way that the addressed functional unit is actuated in accordance with the key unit signal. If, for example, if the resident pushes the top of the button unit on the left, the lights are turned on, the central unit must be programmed so that the signal emitted by the button unit when the upper left button is pressed, into a switch-on for the light implemented and transmitted to the appropriate lamp.

As already mentioned above, for example, the signal for the upper left button in the central unit can be flexibly stored. Thus, for example, the signal in the central unit can be interpreted as keeping the room temperature constant, to which the central unit can flexibly actuate, for example, the blinds or the radiator valve. Many examples are conceivable for such a flexible use of the home automation and home information system according to the invention, such as the regulation of the indoor air humidity, the brightness of the building, the noise level within the building, etc.

But also a virtually flexible key assignment is possible with the house automation and home information system according to the invention, in which case again the central unit can interpret the inherently invariable key signal differently depending on the framework conditions. An example of this is that the upper left button switches the light on and off in the dark at night and triggers the opening and closing of the blinds during the day when it is light. Since a key can thus have many functions which can be selected freely, depending on the central unit or a higher-level command unit, the keys are preferably to be labeled so that the user of the key unit can recognize the function assigned by the key. Here, words or symbolic marking of the keys, but also the Braille font, can be thought of. Also, a colored combination, such as blue for heating colder, etc. can be used here. Care should be taken that the identification of the buttons is not only visible on the holder, but also especially when the button unit is removed from the holder and used in the manner of a remote control for the home automation functional units.

According to the invention, a key unit is preferably used which has an autonomous battery-free power supply. These include scanner units which obtain their required energy, for example from the movement of the button, for example by induction, or which use the ambient heat for the provision of energy. Such energy harvesters are known from the prior art and are preferably suitable for use in the home automation and home information system according to the invention. In particular, such energy harvesters comprise components which convert energy from temperature differences, light, pressure or movements into electrical energy. A key unit according to the invention is configured, for example, with a solar module or an inductive generator, which provides electrical energy when a key is actuated. Optionally, the key unit has an additional energy storage, so that electrical energy is available when no primary energy is ready for conversion. However, the home automation system according to the invention is also battery-operated, although certain maintenance intervals or battery charge controls should be provided. However, according to the invention, a so-called energy harvester offers itself due to its low maintenance.

Particularly user-friendly is the flexible handling of the stylus unit either stationary or location independent. Thus, especially the comfort for the operation of the home automation control, ie the control / regulation of the individual consumers and functional units can be increased enormously for the user / resident, since he can carry the button unit with him, and not every time he has the state of a Function unit wants to change, must run to a predetermined fixed location. On the other hand, the fixed attachability of the holder for the stylus unit has the advantage that the portable stylus unit may have a predetermined location where it can be stowed for easy retrieval. The invention will be explained in more detail with reference to embodiments which are illustrated in the following figures.

FIG. 5 shows a detailed view of the housing of the double pushbutton according to FIGS. 2 and 3.

FIG. 1 shows a block diagram of a home automation system 1 according to the invention, which uses home automation switching devices 2 according to the invention. The home automation system 1 has a programmable electronic central unit 4 with integrated receiver 5, which has electronic memory and processor units, not shown, and which is operatively connected to an input unit 9. The connection may be via connection lines 7 or as a wireless connection 6, e.g. via LAN or WLAN. The central unit 4 is also connected to building services function units 8 such that they can activate or terminate their function in accordance with signals transmitted to the central unit 4. For this purpose, the central unit is operatively connected to the individual functional units 8 via further connecting lines 7 or via wireless connections 6. In the latter case, the respective functional unit 8 is designed such that it can be controlled by wirelessly transmitted signals. It is then, for example, to an associated power supply, for example to the electrical home network, connected.

The central unit 4 is operatively connected to at least one home automation switching device 2, wherein the wireless connection 6 can take place by means of electrical, acoustic or optical signals which are emitted by the home automation switching device 2 when actuated by an operator. θ

person to be sent. The central unit 4 is provided for this purpose with receiving means, not shown. Such transmitting and receiving devices are known per se, so that it needs no further explanation here. It is understood that when using optical signals, for example in the infrared range, the central unit 4 or this associated optical receiver in the field of view of the home automation switching device 2 must be. A transmission of optical signals to the central unit via optical fibers whose input side in certain rooms, for example, on the ceiling, are arranged, is also conceivable and is within the scope of the invention. The domestic switching device 2 sends in accordance with the input by the operator in each case one of several signals available to her, with the individual signals each differ by at least one characteristic property. This property can be, for example, the wavelength or frequency of the transmitted signal or the duration of the transmission or a different timing or other coding. The individual signals are each permanently assigned to a specific operating element of the domestic technology switching device 2, so that each signal permits identification of the associated operating element on the basis of its characteristic by the central unit 4. Under operating element is here and below always a particular component to understand, which is able to cause the transmission of a particular signal. By way of example, the double pushbutton described in greater detail with reference to FIGS. 2 to 5, in which each of the two pushbuttons is assigned two operating elements which can be activated optionally by tilting the pushbutton in one or the other direction. The double button according to Figure 2 to 5 thus has four controls. In the design of the home automation switching device 2 is preferred that each one

Domestic switching device 2 together with each signal also emits an individually predetermined coding, which allows an assignment of the signals to a specific home automation switching device 2. The central unit 4 is provided for receiving and evaluating the signals with receiving and analyzing means which are designed and programmed for this purpose. Such means are known from wireless control technology and will therefore not be explained further here.

The central unit 4 is programmed according to the invention in such a way that, on receipt of a signal from a specific clock-setting device 2, it determines from which operating element of the building services switching device 2 the signal was transmitted. This finding is compared with a programmed preset which is sent to the center via the input unit. 4 unit is transmitted and stored there. The default determines which functional unit 8 is driven upon receipt of the signal and set by the central unit 4 in operation, switched off or otherwise operated. The specification of the functional unit, which is assigned to a specific operating element of the domestic technology switching device 2, can be freely selected by the operator. It can change the assignment at any time after a first specification, for example when the home automation system is put into operation for the first time. Thus, it is possible to initially provide a specific operating element for the actuation of a lighting device and to use the same operating element of a specific home automation switching device 2 at a later time for the switching on or off of a video appliance.

FIG. 1b shows, in addition to the receiver 5.a integrated in the central unit 4 according to FIG. 1a, further receivers 5.b and 5.c, which are connected to the central unit 4. The home automation system is installed in a building with four different areas a, b, c and d, which here represent four different rooms of a house. The central unit 4 with receiver 5.a is arranged in the first room a. In the rooms b and c each have a receiver 5.b or 5.c is arranged. If a key-bound, one-to-one signal is transmitted by the domestic technology switching device 2 located in room a, the central unit 4 recognizes by comparing the field strength of the signal at the various receivers 5.a, 5.b and 5.c on the basis of a location determination algorithm the home automation switching device 2 is located in room a. Thus, the functional unit 8 associated with the key-bound signal in the central unit 4 for room a, in this case the functional unit 8.a located in room a, is activated. A corresponding behavior shows the home automation system 1, even if the home automation switching device 2 is taken from room a in the room b. For the space b, however, the key-bound signal, which has previously activated the functional unit 8.a in room a, is now linked to the functional unit 8.b. A corresponding location-dependent linkage between key-bound signal and functional unit 8 is stored in the central unit 4. Accordingly, the function unit 8.c stored for the key-bound signal is activated in room c. Thus, the key assignment of a home automation switching device 2 changes depending on their location.

In space d, no receiver 5 is arranged. If the domestic switching device 2 is located in the space d, the receivers 5.a, 5.c and 5.c each receive a signal with a specific field strength. On the basis of an evaluation algorithm for the location of the domestic switching device 2, which takes into account the field strength at the different receivers 5, the central unit 4 can recognize that the domestic appliance switching device in the room d located. Thus, when transmitting a key-bound signal in space d, the functional unit 8.d assigned to this room is activated.

FIG. 2 shows a home automation switching device 2 according to the invention in a perspective view. The domestic switching device 2 is shown here as a double push button 3, which represents a particularly preferred design, since it is similar to the usual switches used in buildings. The domestic switching device 2 has a key unit 10 with two adjacent keys 11, which are mounted in a housing 16. The purity button 10 is preferably releasably connected to a holder 30, from which a base plate 31 can be seen.

The holder 30 is fixed on its base plate 31 to a wall or other surface, such as a wooden plate or a glass, which can be done by screws or gluing, depending on the material. During installation, the base plate 31 is preferably installed in a stationary manner, for example at the usual position of an electrical switch. The button unit 10 can then be operated in this position, which can be permanently secured by gluing or screwing your bottom with the base plate 31. A permanent fixation of the domestic switching device 2 is also favorable if it is to be expected vandalism or unauthorized removal, such as in a classroom.

Alternatively, it is possible to remove the button or key unit 10 from the holder 30, when it is held on this easily releasable locking devices by magnets 19, 34 (see Figure 3) or not shown. In this case, the key unit 10 can be operated at arbitrary locations in the reception area of the CPU 5. It is similar to a wireless remote control.

FIG. 3 shows an exploded drawing of the domestic switching device 2 according to FIG. From top to bottom, the essential components or assemblies of a double sensor 3 according to the invention are shown. These include the key unit 10 with the two buttons 1, rockers 12, the switching and transmitting module 20, the housing 16 and the cover 17 and four magnets 19. Details of the switching and transmitting module 20 will be explained with reference to FIG 4.

In the lower part of Figure 3, the holder 30 can be seen. It comprises from top to bottom a Beschrrftungsträger 38, an information carrier 37, the base plate 31 with four recesses 33 for receiving additional magnets 34. The base plate 31 has a trough 36 and two openings 32. The openings 32 allow the passage of screws for permanent attachment of the bracket 30 to a wall or other surface. The trough 36 serves to receive the label carrier 38 and / or the information carrier 37. These are releasably fixed in the trough by means not shown, such as latching devices, and carry information about the assignment of the switching positions of the keys to certain functional units 8. When the key unit 10 is removed from the holder 30, the information is readable. It is understood that when changing the assignment of the key assignment to certain functional units 8, the label of the Beschriftu ngsträger 38 and / or the information carrier 37 is changed accordingly. A corresponding inscription may additionally or alternatively also be arranged on the rear side of the key unit 10, which is indicated in FIG. 3 in that the housing 16 has a compartment on its underside which can be closed by the cover 17. In this compartment, which preferably has a transparent outer side, a label carrier 38 can be inserted with the label of the key assignment. A double-sided adhesive tape 35 is also shown in FIG. It serves as an alternative to

Screws for fixing the holder 30 on a flat surface, such as a wall, a wooden panel or on tiles.

In the assembled state of the double push-button 3, the two keys 11 are attached to a respective rocker 12 and are held by this. The rocker 12 has receptacles 13 for axle pins 14, 22, to which it is plugged latching and about which it is tiltable to actuate the key. The Wrppe12 is self-recovering, which can be effected or supported for example by springs, not shown, and has a neutral position and two switching positions. By tilting a button 1 and thus the associated rocker 12 in one or the other direction a switching position is activated in each case, whereupon the switching and transmission module 20, a corresponding signal is emitted.

The axle pins 14, 22, of which only one can be seen in FIG. 3, are arranged on the housing 16 and / or in the switching and transmission module 20, an axle pin 14, 22 being provided on each longitudinal side of the two rockers 12. Each rocker 12 is thus mounted on both sides.

The housing 16 contains the switching and transmission module 20, which is fixed by means of detents 21 in the housing 16. In the four corners of the housing are recesses 18, in each of which a magnet is inserted. These magnets 19 are preferably designed as cylindrical bar magnets with poles on the end faces. They cooperate with the magnets 34 in the wall bracket 30 whose polarity is opposite to that in the key unit 10. The two components of the domestic switching device 2 are thus characterized by mag- netic forces releasably connected. Instead of magnets could be in one of the two modules also a suitably shaped ferromagnetic material, such as soft iron, are used, but this would lead to a reduced holding force compared to magnets.

As an alternative to magnets, the two assemblies, key unit 10 and wall mount 30, the home automation switching device 2 are also held together via plug, snap or locking devices in a detachable manner. FIG. 4 shows a detailed view of the switching and transmitting module 20 shown in FIG. 3 according to FIG. 3. The switching and transmitting module 20 has a housing block 24 on which a plurality of detents 21 and axial pins 22 are formed. The detents 21 serve to fix the switching and transmitting module 20 in the housing 16 of the key unit 10, where they cooperate with complementary notches 40. The axle pins 22 allow plugging of the keys 11 supporting rockers 12. From the housing block 24 protrude four transmission pins 23, which transmit the movement of a key 1 1 via the rocker 12 in the interior of the housing block. This movement triggers in each case one of the pressed key position corresponding signal generated by the electronics of the switching and transmitting module 20 and transmitted as a radio signal to the central unit 5. The electronic components located in the interior of the switching and transmitting module 20, such as devices for generating and transmitting coded radio signals, are familiar to the person skilled in the art. The transmitted signal is coded in such a way that it allows the central unit 5 to identify the emitting key unit 10 and the depressed key 11 and to effect the required action for actuating the addressed functional unit 8. The actuation of a key 11 causes via the movement of the transmission pins 23 in this case the generation of electrical energy, for example via piezoelectric means or electromagnetic induction. This energy is sufficient to enable the generation, encoding and transmission of radio signals, as already explained. The switching and transmission module 20 thus requires for its operation neither a connection to an external power source nor an internal battery. The achievable with this known technology cash ranges of signal transmission by radio in buildings are about 30 meters.

The switching and transmitting module 20 is largely symmetrical with respect to its mechanical components, wherein a plane of symmetry passes through the parting line between the two keys and another plane of symmetry is perpendicular thereto, as the figure is readily removable. However, in order to ensure reliable and reliable assignment of key positions, the housing block 24 can be equipped with a symmetry-disturbing element, be provided as a nose, which cooperates with a complementary element such as a recess 25 in the housing 16 of the key unit 10. As a result, the housing block 24 can be inserted into the housing 16 only in a predetermined orientation. The exterior of the housing 16 is also provided with a label or mark which makes it recognizable which is the correct orientation of the key unit.

FIG. 5 shows a detailed view of the housing 16 of the double sensor 3 according to FIGS. 1 and 3 which is symmetrically constructed with respect to a center plane passing through the gap between the two buttons. Evident are the axle pins 14, the recesses 18 for receiving the magnets 19 and the detents 40 for fixing the switching and transmitting module 20 in the housing 16 of the key unit 10. Because of the perspective view some of the above parts are hidden
