Rfid - a scanning system without external energy supply to the interrogation of the structural well-being

摘要

The present invention provides: a rfid - based scanning system (t) comprising a piezoelectric arrangement (2), which is configured to be applied to at least in sections and / or at least in sections is applied to a structure (1), a rfid - transponder (3), which is connected with the piezoelectric arrangement, and an antenna (5) which, with the rfid - transponder is connected and / or in the rfid - transponder is integrated, and it is also possible to use a with the rfid - transponder energy connected memory bank, wherein the piezoelectric arrangement (2) and / or of the rfid - transponder (3) is / are designed for converting the kinetic energy, which is supplied by said structure, into electrical energy, which is used and / or can be used to supply of the rfid - transponder (3) with energy and for the generation of sensing information with respect to a state of said structure, wherein the energy memory bank electrical energy, which by means of mechanical stresses or vibrations from the said structure has been generated can accumulate in order to provide the system continuous energy or low - working cycle - energy available to. A reading device (r) sends a request to the rfid - the transponder and receives the said sensing information with respect to a state of the structure. The antenna is designed zumübertragen said sensing information and / or the information derived therefrom to the rfid - reading device (r) and / or for receiving a rf - signal from said reading device.
