LOCATION OR INVENTORY SYSTEM

摘要

The invention relates to a location or inventory system for objects which are provided as power consumers with a terminal for a power supply network, and which each comprise an individual object identifier as part of the location and inventory information that can be verified from a central location. A generator for a location identifier is provided in the area of a power network line unit for the energy-receiving system. The source of energy is marked with the location identifier as an additional piece of information. Said location identifier differs from other location identifiers in the power network. The generator is permanently connected to said power network line unit in an interactive manner. The location identifier can only be transmitted from the power network line unit in a direction of the at least one energy-receiving system which is connected to said power network line unit. A receiver for this location identifier is also provided in the energy-receiving system. In addition, a converter is provided which converts the location identifier, together or in association with the object identifier, into a data format which is suited for transmission.
