Home communication system with at least one door station and at least two home stations

摘要

It is proposed a home communication system with at least one door station (1) and at least two home stations (2-5), wherein all stations (1-5) are connected to a bus (8), via which both the communication and the power supply is unwound and wherein a power supply unit (6) is connected to the bus (8). At least one power coordinator (7) is provided for the management with regard to a coordinated energy consumption of the stations (1-5), which contains the current energy consumption values of the stations (1-5) and the maximum permissible energy capacity of the voltage supply unit (6) communicates with the stations (1-5), whereby the stations (1-5) their future required energy needs at the performance coordinator (7) login / request. The power coordinator (7) decides, on the basis of the current energy consumption values available to it and the maximum permissible energy loadability of the voltage supply unit, whether the requested energy requirement is to be provided by the voltage supply unit (6).
