SYSTEM OF NETWORKED DOMESTIC APPLIANCES HAVING A JOINT TIME BASE AND IDENTIFICATION DEVICE OF A RESPECTIVE PHASE OF THE BUILDING INSTALLATION, AND METHOD FOR OPERATING SUCH A SYSTEM

摘要

The invention relates to a system of networked domestic appliances, in particular a management system, in particular an energy management system, comprising essentially a superordinate unit for executing the management, wherein a single domestic appliance comprises an identification device of a respective phase of a three-phase power supply of the underlying building installation. The invention is characterized in that the domestic appliances HL1_1 to HL3_n in the system HEMS have a joint time base CL1_1 to CL3_n, wherein the identification device IL1_1 to IL3_n of the individual domestic appliance comprises a time-measuring device TI in order to measure a zero crossing NDG1 to NDG3 of a supply voltage applied to the domestic appliance in relation to a jump signal INT that can be transmitted to all domestic appliances of the system. According to the invention, the identification device IL1_1 to IL3_n comprises a phase attributor ZU that can evaluate a result of the time measurement of the time measurement device TI so that the relevant phase to which the domestic appliance is connected can be determined and displayed ANZ. The invention further relates to a method for operating such a system.
