Field of the Invention
The present invention relates to a method for identifying at least one electrically powered device by a power supply device via a powerline connection, preferably for execution with a system.
The present invention also relates to an electrically powered device for identifying with a power supply device, comprising a powerline socket for connecting the electrically powered device via a powerline connection to a core power supply, a core device for performing an intended application of the electrically powered device and an identity sender.

FIG. 1 is showing an electrically powered device and a power supply device according to a first embodiment of the present invention.
In FIG. 1 reference sign A denotes an electrically powered device. The electrically powered device A comprises a core device 1 which performs an intended application for the electrically powered device. An intended application may be measuring a temperature, providing a telephone connection, showing a television program, etc. The core device 1 is connected via a powerline connection 30 to an identity sender 2. The identity sender 2 is connected via the powerline connection 30 to a powerline socket Aa for providing electrical power to the electrically powered device. Further the powerline connection 30 is used for identification of the electrically powered device A. The electrically powered device A is further connected via the powerline connection 30 to a power supply device B, comprising an identity receiver 4, core power supply 5 as well as a confirmation sender 4a. The core power supply 5, the confirmation sender 4a and the identity receiver 4 are connected to the powerline connection 30 and in particular via a powerline socket Ba.
When connecting the electrically power device A via the powerline connection 30 the identity sender 2 recognizes that power from the core power supply 5 via the powerline connection 30 is provided to the electrically powered device A. The identity sender 2 is formed such to delay the switching on of the core device 1 until the identification of the electrically powered device A is completed. The identity sender 2 therefore generates a specific load according to unique identifier of the electrically powered device A on the powerline connection 30 which is recognized and received by the identity receiver 4 of the power supply device B. The power supply device B comprises the aforementioned confirmation sender 4a which sends a confirmation signal to the electrically powered device A, preferably via the powerline connection after a successful identification of the electrically powered device A by the identity receiver 4 of the a power supply device B, so that the electrically powered device A recognizes the confirmation signal. The successful identification is completed. After generating the specific load and after successful identification by the specific load of the electrically powered device A by the power supply device B the identity sender 2 in the electrically powered device A switches on the core device 1 for the intended application of the electrically powered device.
