Control device and control system for an electromotive adjusting drive of an item of furniture
A control system for controlling an adjusting drive for an item of furniture includes a control device connected to the adjusting drive, and a first operating unit. The control device is configured to receive signals from the first operating unit transmitted wirelessly via a transmission unit over a first transmission link, and to control the adjusting drive as a function of the signals received. The control device is also configured to receive further signals from a second operating unit transmitted wirelessly via the transmission unit over a second transmission link and to control the adjusting drive as a function of the further signals received. The second transmission link differs from the first transmission link.
1. A control system for controlling an adjusting drive for a piece of furniture, said control system comprising:
a first operating unit generating first control signals and/or data in response to a first user input;
a second operating unit generating second control signals and/or data in response to a second user input;
a transmission unit; and
a control device connected to the adjusting drive, said control device configured to receive the first control signals and/or data from the first operating unit wirelessly via the transmission unit over a first transmission link and to control the adjusting drive as a function of the received first control signals and/or data, said control device further configured to receive the second control signals and/or data from the second operating unit wirelessly via the transmission unit over a second transmission link and to control the adjusting drive as a function of the received second control signals and/or data, with the second transmission link differing from the first transmission link, wherein the control device is adapted to suppress received control signals and/or data over one of the first and second transmission links when control signals and/or data are already being transmitted over the other one of the first and second transmission links.
2. The control system of claim 1 , wherein the transmission unit comprises a shared antenna for the first and second transmission links.
3. The control system of claim 1 , wherein the first and second transmission links use a same ISM (Industrial, Scientific, Medical) frequency band.
4. The control system of claim 1 , wherein the first and second transmission links use different frequency channels of a same frequency band.
5. The control system of claim 1 , wherein the first and second transmission links have different protocols.
6. The control system of claim 5 , wherein at least one of the protocols is a Bluetooth protocol.
7. A control device for controlling an adjusting drive for a piece of furniture, said control device comprising:
an antenna; and
a transmission unit configured to receive wirelessly first control signals and/or data transmitted from a first operating unit generated in response to a first user input over a first transmission link and to receive wirelessly second control signals and/or data transmitted from a second operating unit generated in response to a second user input over a second different transmission link for controlling the adjusting drive, said transmission unit comprising a transmitting and receiving module connected to the antenna and configured for coupling simultaneously to the two different transmission links, wherein the control device is adapted to suppress received control signals and/or data over one of the first and second transmission links when control signals and/or data are already being transmitted over the other one of the first and second transmission links.
8. The control device of claim 7 , wherein the transmitting and receiving module is configured as a system-on-chip.
