Abstract

The name of the invention is a building communication system with at least one door station and at least two residence stations, wherein all the stations (1-5) are connected to a bus (8), communication and energy supply can be performed via the bus, wherein a voltage supply unit (6) is connected on the bus (8). At least a power coordinator (7) used for performing management of coordination of energy consumption of stations (1-5), the power coordinator is provided with a current energy consumption value of the stations (1-5) and a maximal permitted energy load carrying capability of a voltage supply unit (6), and the power coordinator is communicated with the stations (1-5), wherein, the stations (1-5) notifies / requests the required energy demand in the power coordinator (7). The power coordinator (7) determines whether the requested energy demand is provided by the voltage supply unit (6) on the basis of the current energy consumption value and the maximal permitted energy load carrying capability of the voltage supply unit.

Description

technical field

[0001] The invention relates to a building communication system with at least one gate station and at least two residential stations, wherein all stations are connected to a bus via which not only communication but also energy supply takes place, and wherein a voltage supply unit is connected to the bus . Background technique

[0002] Known from DE 10 2006 051 133 B3 is a building installation with at least one residential station, a door station, at least one door opener and a bus, the residential station, door station and door opener being connected to the bus, wherein the bus is used for Supply energy to the door opener. The control of the door opening device requires relatively large power. Correspondingly, in response to a door opening signal corresponding to the door opening device, at least one dwelling station / door station is disconnected from the bus with respect to its energy supply or adopts an energy-saving mode.

Embodiment Construction

[0017] exist figure 1 shows a building communication system with a door station and a plurality of residential stations, which are connected to a bus, in particular a two-wire bus. A door station 1 and four residential stations 2, 3, 4, 5 can be seen. The bus 8 is not only used for communication between the stations 1-5, but also for energy supply. The voltage supply unit 6, which is preferably designed as a switching network component, enables the energy supply of all stations 1-5. The voltage supply unit 6 includes, for example, a power coordinator 7 . Alternatively, the power coordinator 7 can also be designed in the form of a separate device, or integrated in one or more or all stations 1-6. The power coordinator 7 can generally be regarded as a logic mechanism (logische Instanz), which can be implemented at any station, but also at one or more gate stations or residential stations.

[0018] The main criterion of the shown building communication system is that the stat...
