Definitions

  • the invention relates to a key with a transponder chip and with an antenna connected to the transponder chip for sending key-specific electronic signals.
  • Such a key is for example from the DE 199 06 578 A1 known.
  • a single encoder is arranged in a shaft.
  • the key can be inserted into a closing channel of a lock cylinder.
  • the lock cylinder has a code receiver with an antenna.
  • the antenna is arranged in front of the code transmitter of the key inserted into the lock channel.
  • the code transmitter of the key can be supplied with electrical energy and read out by an electromagnetic field generated by the antenna of the code receiver.
  • Such code transmitters usually have an antenna and a transponder chip, which form a resonant circuit with the electromagnetic field generated by the antenna of the code receiver, via which electrical signals, such as a code stored on the code transmitter, can be transmitted.
  • the antenna of the known encoder is designed by its size and orientation to be read by a lock cylinder.
  • Today's locking systems have in addition to locking cylinders for inserting a key and electronic locking devices that are controlled by a reader.
  • readers are in key fobs and Check cards arranged code transmitter become known. Attempting to drive such readers with code receivers of a known key, this has the disadvantage that the reading distance is very small. The key must therefore be held with the very small, located in the shaft antenna exactly in the intended position of the reader. However, this is very uncomfortable.
  • the invention is based on the problem of further developing a key of the type mentioned at the beginning in such a way that it has versatile possibilities for reading out by different code receivers.
  • a second antenna for sending the key-specific electronic signals is connected to the transponder chip, wherein the antennas have different sizes and / or orientations and wherein the transponder chip is exclusively readable via one of the antennas.
  • a third and further antennas may be connected to the transponder chip. Due to the different sizes and orientations, one of the antennas may be designed to be held in front of a reading device and the other of the antennas to be inserted into a locking cylinder. In the simplest case, the antennas could be designed as directional antennas or art and structure differ so that automatically one or the other antenna is excited depending on the design of the reader. Of course, a shield for generating the intended different orientations of the antennas may be arranged between the antennas.
  • the excited by an external field antenna is independently connected to the transponder chip according to another advantageous embodiment of the invention, when between the transponder chip and the antennas each an electronic circuit is arranged and when the electronic circuits for exclusive connection of the energy-carrying antenna formed with the transponder chip is.
  • This design allows conventional transponder chips to be used.
  • the non-excited antenna is not connected thanks to the invention with the transponder chip, whereby the interference of the signal of the other antenna is avoided.
  • the structural complexity for selectively reading out the transponder chip via the one or the other antenna can be kept particularly low according to another advantageous development of the invention, if the transponder chip has a separate rectifier for each of the existing in the key antennas.
  • the components for supplying the transponder chip with electric current and for the exclusive connection of the transponder chip to the respective antenna are integrated in the transponder chip itself. This also leads to a high range for reading the transponder chip, because external electronic components are thereby avoided.
  • the differences in the size and orientation of the antennas can be easily produced according to another advantageous embodiment of the invention, when one of the antennas is designed as a ferrite antenna and the other antenna is designed over a large area.
  • the key is according to another advantageous embodiment of the invention for different application environments, when one of the antennas is arranged in a provided for insertion into a lock channel of a lock cylinder shaft and the other of the antennas in a gripping hand intended Reide.
  • FIG. 1 shows a lock cylinder 1 with a rotatably mounted in a housing 2 core 3.
  • the core 3 is rotatably connected to a cam 4. At its end faces, the core 3 each have a closing channel 5 for insertion of a key 6.
  • the lock cylinder 1 has an electromagnetic locking device 7 for selectively blocking or releasing the movement of the core 3 relative to the housing 2.
  • a receiving antenna 8 is arranged in a remote from the end face of the lock cylinder 1 region of the housing 2.
  • the receiving antenna 8 is connected to a control device 9, which controls the electromagnetic locking device 7.
  • In the housing 2 also designed as a coin cell energy storage 10 is arranged.
  • the energy storage device 10 supplies the control device 9 and the blocking device 7 with electrical energy.
  • the key 6 has a closing channel 5 correspondingly shaped shaft 11 and a Reide 12 as a handle.
  • a code transmitter 13 is arranged in the shaft 11 of the key 6, a code transmitter 13 is arranged.
  • the code transmitter 13 has a transponder chip 14 with two antennas 15, 16 connected thereto.
  • a first antenna 15 has small dimensions and is arranged in the shaft 11. This antenna 15 is opposite to the arranged in the lock cylinder 1 receiving antenna 8.
  • the first antenna 15 thus has the size and the orientation to act together with the receiving antenna 8 in the lock cylinder 1.
  • a second antenna 16 of the key 6 has large dimensions and is arranged in the Reide 12. This second antenna 16 is not excited when the transponder chip 14 is read out via the first antenna 15.
  • the arranged in the shaft 11 antenna 15 may be formed, for example, as a ferrite antenna, while arranged in the Reide 12 antenna 16 is designed over a large area.
  • FIG. 1a schematically shows the key 6 from FIG. 1 in front of a reading device 17 with a large receiving antenna 18.
  • This reading device 17 controls a schematically illustrated access control system 19. If you move the key 6 in the vicinity and thus in the reception area of the reading device 17, first the large dimensions and having in FIG. 1 illustrated second antenna 16 of the key 6 excited. Thus, the transponder chip 14 is read out via the second antenna 16 of the key 6.
  • FIG. 2 shows a first embodiment of a circuit diagram of the encoder 13 of the key 6 from FIG. 1 , It can be seen here that an electronic circuit 20, 21 is respectively arranged between the transponder chip 14 and the antennas 15, 16. The electronic circuits 20, 21 are activated via the respective antenna 15, 16 and supplied with electric current. The respectively first excited electronic circuit 20, 21 establishes the connection of the transponder chip 14 with the respective antenna 15, 16. In addition, the other electronic circuit 20, 21 are blocked in order to avoid mutual interference of the emissions of the antennas 15, 16.
  • FIG. 3 shows a further embodiment of a circuit diagram of the key 6 FIG. 1 ,
  • the transponder chip 14 has a logic circuit and two rectifiers 23, 24 connected thereto.
  • the rectifiers 23, 24 connect the logic circuit 22 to one antenna 15, 16.
  • the transponder chip 14 is itself for the direct connection of several antennas 15 , 16 designed.
