Definitions

  • the invention is based on a method or a device according to the genre of independent claims, as from German patent application DE-A-19703998 are known. Inside is one from a base station as well as several associated actuators Telecontrol device described, for example ensures the lawful use of a motor vehicle. The facility also allows the remapping of others Actuators to the base station. Under the Prerequisite that a specific, as the main operating element operating actuator is present, transmits the base station a reassignable actuator assignment information in the form of a serial number, a cryptic key code and one of the Base station each newly assigned group number. Not on a reassigned actuator is transmitted additional information, which the functional scope of the actuator determine further.
  • WO 94/16415 is a deception-proof credit card management system known, consisting of a card reader for credit cards and a central computer. This system allows a reallocated credit card using an old one Release credit card. You can choose the reallocated one and the already assigned credit card first can be entered. The release or blocking of the respective Credit card is found in the central computer and not on the credit card instead, the identification data of the new and old cards are different.
  • Telecontrol devices such as those mentioned above, are used for the Communication a low frequency field of e.g. B. 150 kHz.

  • the information stored in the actuator fully readable, but only once. To successful readout will be read out again by a non-removable lock prevented. They will be advantageous to be taken over by an actuator to be replaced Assignment information is first passed to the base station and in temporarily stored in a volatile memory. Subsequently they are transferred to the actuator to be reassigned. This simplifies the implementation of the reallocation process, since only the actuator to be replaced in the immediate vicinity in the event of an empty battery to be brought to the base station. A duplication of an actuator is only possible under the condition that there is only one actuator to be reassigned in the range the base station.
