| 摘要 |
The invention relates to a system (1) for providing relevant device information data for an energy device (2), wherein the energy device (2) outputs a dynamically generated code from internal context data (device ID, manufacturer ID, etc.) and external context data (geographical position, user name and user qualification), and a user's mobile terminal device (3) captures the code optically (QR code, bar code) or acoustically. After successful decryption of the code by a decryption unit (3D) of the mobile terminal device (3), the mobile terminal device (3) establishes a data connection to a server (6), which provides relevant device information data for the energy device (2) (operating instructions, installation instructions, order form) that is relevant for the context specified in the context data. |
