Definitions
- the invention relates to a control system for controlling at least one adjusting drive for a piece of furniture, comprising a control device connected to the at least one adjusting drive and an operating unit, wherein the control device is configured to wirelessly transmit signals of the operating unit transmitted via a transmission link by means of a transmission unit receive and control the at least one Versteilantrieb depending on the receiving signals.
- the invention further relates to such a control device for the at least one Versteilantrieb.
- Versteilantriebe often referred to as electromotive furniture drives are installed in reclining and seating furniture to furniture parts such as seats, backrests, footrests, etc. relative to a base body of the furniture and to be able to adjust relative to each other comfortably.
- Adjustable seating furniture in particular so-called television or relaxation armchairs, usually has a mechanically relatively complex furniture fitting which, in cooperation with a large number of levers and rods, enables a complex sequence of movements of the various upholstered units mounted on it.
- a frame is provided as a basic element that carries a slatted frame with movable head and foot parts.
- the above-mentioned control device is arranged on or in the furniture, the operating commands of a user receives from an operating unit and converts into control signals for the Versteilantriebe.
- Control device and operating unit form the control system for the Versteilantriebe.
- the Versteilantriebe wireless control units which have at least one control element and a ne transmission unit for the wireless transmission of signals depending on an operation of the at least one control element.
- a wireless control unit often referred to as a remote control
- Wireless control units are convenient easy to use and also through the availability of dedicated integrated circuits. Due to the high number of units in which such circuits are used in consumer electronics in remote controls for TVs, etc., the circuits are also inexpensive.
- Such wireless operating units are usually tailored specifically to a specific control device or specific type of control device and are distributed as an initial configuration with the control device. Due to the higher range, radio-based operating units have prevailed over those with infrared light or ultrasound.
- the wireless transmission usually takes place via a manufacturer-specific, proprietary protocol within one of the usable frequency ranges, in particular within one of the so-called ISM (Industrial, Scientific, Medical) bands.
- WLAN Wireless Local Area Network
- Bluetooth or other short-range wireless systems
- NFC Near Field Communication
- control device is additionally set up to receive wirelessly transmitted via a further transmission link further signals another control unit by means of the transmission unit and to control the at least one Versteilantrieb of the received further signals , wherein the further transmission path is different from the transmission path of the aforementioned control unit.
- a single control device can be used both for use with the proprietary and for use with a mobile device.
- the individual device is thereby more expensive and possibly at least slightly more expensive to produce, nevertheless an overall advantage results for the manufacturer since the parallel development, production and storage of two differently designed control units is eliminated.
- the user there is the advantage that he can alternatively use a mobile device for control even in the presence of a proprietary operating unit.
- the transmission unit has a shared antenna for both transmission links. This is advantageously possible if both transmission links use the same or in the frequency space close to each other lying frequency bands.
- both transmission links may preferably use a same ISM frequency band, e.g. B. by different frequency channels of this same frequency band are used.
- the transmission link and the further transmission path can also differ in their used protocols.
- At least one of the protocols is preferably a Bluetooth protocol, which is usually dominated by all modern mobile devices. Particular preference is given to using a so-called low-energy Bluetooth protocol, which advantageously does not require a permanently existing transmission path. In this way, periods of time during which the low-power Bluetooth connection is not active can be used to transmit signals or data from the other transmission link, for example from the transmission path using a proprietary protocol.
- a non-active low-energy Bluetooth connection is given in principle, if there are no signals or data of the other or the other transmission link. In these periods then signals or data of the (proprietary) transmission link can be transmitted.
- the proprietary transmission via the transmission path describes a simplified signal and data structure adapted to the furniture and to the control device, since only simple adjustment commands have to be transmitted. This allows transmission of the commands in very short time intervals.
- the further transmission path also has a likewise adapted signal and data structure, which also allows short time segments for transmitting the signals or the data.
- the time gaps are accordingly large. Their length is considerably greater and corresponds to at least three times the time of transmission of signals or data.
- control device The requirements for the control device are further adapted such that an agreement with regard to the transmission release between the operating units does not have to be made. Because in practice, the user will always use only one of the operating units. Nevertheless, the control device is adapted to suppress received signals or data, if already signals or data are transmitted via one of the other transmission link. Thus, double operations or conflicting operating intentions are excluded.
- the invention is not limited to the use of a Bluetooth connection through the further transmission link.
- the further transmission path may also include other transmission protocols such as Wise ZigBee, WLAN or lead but those that transmit signals or data within individual time periods.
- a control device for controlling at least one adjusting drive has a transmission path for receiving wirelessly transmitted signals of an operating unit for controlling the at least one adjusting drive. It is characterized in that the transmission unit has a transmitting and receiving module, which is connected to an antenna and which can be coupled simultaneously with two different transmission links. In this way, the transfer unit with minimum component cost with two different operating units work together.
- the transmitting and receiving module is designed as a system-on-chip (SoC). Suitable transmitting and receiving modules are now conveniently available due to the proliferation of, in particular, the 2.4 GHz (Gigahertz) band for use in mobile devices.
- SoC system-on-chip
- FIGURE shows a block diagram of a control system of an electromotive furniture drive with two Versteilantrieben.
- control system shown in the figure can be used, for example, in a sitting or lying furniture, e.g. an armchair or a bed, equipped with adjustment drives.
- the control system comprises a control device 1 0, with the example here two Versteilantriebe 1 5 are electrically connected.
- the Versteilantriebe 1 5 are designed as individual drives, ie each of the Verstelleiltriebe 15 shown is coupled within the cabinet with usually a movable furniture part to its adjustment. Instead of the illustrated individual adjusting drives 1 5, the use of a so-called double drive is conceivable that integrates two Versteilantriebe in a housing.
- each furniture drive is designed to be able to adjust the associated furniture components relative to each other.
- each furniture drive has at least one gear train, it being possible for an abortive gear stage to be designed as a linear gear in the manner of a threaded spindle nut transmission.
- the linear gear can be a rotary gear, eg be upstream in the manner of a worm gear, which is coupled on the input side with an electric motor.
- Another component of the control system is at least one operating unit, via which a user of the system can control the adjustment of the furniture parts on the Versteilantriebe 1 5.
- two operating units 20, 30 are provided, a (proprietary) operating unit 20 and a further operating unit 30, which is formed by a mobile device, here by way of example a smartphone, which has a corresponding program ("app") to the to provide necessary functionality.
- a mobile device here by way of example a smartphone, which has a corresponding program ("app") to the to provide necessary functionality.
- the proprietary operating unit 20 has a plurality of operating elements 21, in the present case keys. Upon actuation of one of the controls 21, a corresponding signal over a transmission path 22 in the direction of
- Control device 1 0 delivered.
- the further operating unit 30 has for operation a touch-sensitive screen (touch screen) 31, via which inputs are accepted by the user. In response to these inputs, a corresponding signal is also output to the control device 10 via a further transmission path 32.
- control device 10 includes a power supply unit 1 1 for supplying power to the control device 10 and also the adjusting drives 1 5.
- the power supply unit 1 1 is in turn supplied with operating current via a power cable 1 2.
- a power supply can also take place via an external power supply.
- a control unit 1 3 is arranged in the control device 1 0, which controls the electric motors contained in the Versteilantrieben 15 and possibly evaluates also arranged in the Versteilantrieben 1 5 limit switch.
- the Versteilantriebe 1 5 are connected for this purpose via cable to Verstellantriebsan- connections 14 of the control device 1 0. It is also possible to provide signal lines within the connections between the adjusting drives 1 5 and the control unit 1 3, via which a position of an output member of the adjusting drive 1 5 is transmitted to the control unit 1 3 in order to control this position signal when activating the adjusting drives 1 5 consider.
- the control device 10 has a transmission unit 1 6, which is coupled to the control unit 1 3.
- the transmission unit 1 6 comprises a transmitting and receiving module 17, which is coupled to an antenna 1 8. About the antenna 1 8 and the transmitting and receiving module 1 7 control signals of the control units 20, 30 are received, which are then forwarded in the form of control commands to the control unit 1 3 for actuating the Versteilantriebe 1 5.
- the transmission unit 1 6 is set up to receive and evaluate signals (quasi) simultaneously from the operating units 20, 30. Both transmission links 22, 32 operate in a same frequency band, so that the signals that are transmitted over both transmission links 22, 32 can be received or transmitted by the one antenna 1 8.
- the transmitting and receiving module 1 7 is able to serve both transmission links.
- Reception module 1 7 is then sufficient to be able to use both transmission links 22, 32.
- Both transmission links 22, 32 are generally bidirectional in order to be able to carry out a protocol which is based on a handshake method.
- the bidirectional design of the transmission links 22, 32 moreover makes it possible to transmit information also from the control device 10 to the operating unit 20, 30, for example, to status messages of the control device 10 and / or the Versteilantriebe 15 to the control unit 20, 30th to send to be able to represent there. This is of particular interest in connection with the further operating unit 30, since information can be displayed on the touch screen 31 in an easy manner.
- the proprietary operating unit 20 uses a proprietary protocol
- the further operating unit uses a standardized protocol, in particular a low-energy Bluetooth protocol.
- the low-energy Bluetooth protocol performs an initialization of a coupling of the devices, so the other control unit 30 and the controller 1 0, by. This coupling is subsequently (logically) maintained even if signals are rarely and / or irregularly exchanged between the units involved. The resulting time gaps can be used to exchange signals between the proprietary control unit 20 and the transmission unit 1 6.
- the transmission links 22, 32 are each utilized only slightly in time. Accordingly, the probability that signals of the transmission links 22 and 32 collide is very low.
- collision protection mechanisms are also provided in the protocols used, which in the event of a collision lead to a repetition of the data transmission with a random delay time, so that a further collision in the retry is practically impossible.
- the transmitting and receiving module is advantageously designed as a SoC, ie a system in which different components are integrated on a single chip.
- these components include, for example, both the analog-operating high-frequency components and a microcontroller for signal evaluation.
