  • This configuration advantageously allows direct actuation of the actuator unit by the secondary control device, which is likewise arranged in a protected manner in the interior of the lock cylinder, while an operation of the secondary control device can be controlled, for example, by the primary control device.
  • a corresponding exchange of data between the control devices can take place via the electrical connection means, which can preferably also provide a coding or encryption of exchanged information.
  • the primary control device is designed to receive information, in particular control commands and / or identification data, from an identification transmitter via an interface unit and to transmit data to the secondary control device as a function of the received information.

  • the primary control device is designed to forward the signals received by the interface unit from the identification transmitter via the electrical connection means to the secondary control device.
  • the primary control device may be relatively simple, because it has to forward substantially only the received signals, while an evaluation of the received signals and possibly subsequent control of the actuator by the arranged in the lock cylinder secondary control device takes place.
  • the primary control device can therefore be made passive, ie even serve only to establish an electrical connection between the interface unit and the electrical connection means leading to the secondary control device.
  • An authorization check and / or other analysis of the data received from the interface unit can preferably be carried out by the secondary control device in this variant.
  • the primary control device may also be designed to amplify the signals received by the interface unit from the identification transmitter and / or to shape them with respect to their frequency spectrum (filtering) and / or to demodulate and / or to to modulate, for example, to ensure a secure data transfer to the secondary control device carrying out a further signal processing or evaluation.

  • an electrical and / or mechanical contacting of at least one component (eg cable end 130a) of the electrical connection means 130 with a contact point 132 in the region of the lock cylinder 110 is formed so that at least the electrical contact of the component 130a to the contact point 132 opens when the Component 130a is subjected to a tensile force which is greater than a holding force of the entire connector, in particular greater than about 1 Newton per plug contact.
  • the contact point 132 can be designed, for example, as a socket in which the end 130a of the cable 130 or a corresponding plug is frictionally held, for example by means of electrically conductive spring means.
  • a tensile force which is too great in relation to the design of the system, acts on the cable 130, at least the electrical connection between the contact point 132 and the cable 130 tears off, so that via the cable no controlled activation of components 118 integrated into the lock cylinder 110 takes place , 114 more can be done.
  • the length of the connecting cable 130 and / or the frictional connection in the contact point 132 and / or the arrangement of the contact point 132 and / or the guidance of the connecting cable 130 in the lock cylinder 110 are to be matched as closely as possible.
  • the electrical connection means 130 comprises a plurality of individual conductors, with at least some conductors e.g. are formed of copper wire.
  • This variant of the invention advantageously enables as it were a "mechanical coding", since after a manipulation attempt, which has the violent removal of the knob 120 to the subject, an unauthorized person from the similarity of the individual conductors of the cable 130 and their large number can not easily derive which Ladder which serves a purpose and / or in which order these are to be controlled.
  • a decoder unit (not shown) may be provided between the electrical connection means 130 and the actuator unit 114, which checks a drive pattern corresponding to a predetermined code on a plurality of electric lines of the electrical connection means 130 and drives the actuator unit 114 only when the correct control pattern has been issued by the control unit 122.
  • a simple, yet efficient code can be achieved, for example, by implementing the decoder unit as a logical functional unit having a plurality of inputs which are to be controlled via the connection means 130 by the control unit 122.
  • the logical functional unit realizes a specifiable logical
  • Transfer function and an output of the logic functional unit is connected to the actuator unit 114.
  • the transfer function it is only with knowledge of the transfer function that the correct combination of input signals can be applied in a targeted manner, which causes actuation of the actuator unit 114.
  • the provision of storage elements in the logical functional unit offers further increased sabotage security.
  • the electrical connection means 130 comprise at least one frangible electrical conductor which, in a tampering attempt, causes the targeted interruption of the electrical connection between the actuator 120 and the components 122, 124 disposed therein and the interior 110b of the lock cylinder 110.
  • the destruction of such a portion of the fragile conductor which is arranged in the inner space 110b of the lock cylinder 110, in particular behind the drill guide 116, so that the deliberately brought break point from the side of the actuator 120 is accessible only by overcoming the Bohrschutzes 116 ,
  • fragile electrical conductors can be manufactured using conventional printed circuit board technology in which printed circuit board structures with defined weakenings or predetermined breaking points are provided. Ceramic substrates or metallized glass bodies may also be provided to form fragile electrical conductors.
  • an actuator 126 (shown in FIG. Figure 3a, 3b ), which is designed to be controlled by the primary control means 122 to unlock a locking mechanism, which locking mechanism is provided to complicate unauthorized opening of a housing of the actuating element 120 or to prevent.
  • the actuator 126 may be designed such that it drives a bolt (not shown) out of a blocking position in which the bolt locks a first housing part (eg grip area) of the actuating element 120 with a second housing part (eg cover) of the actuating element 120 ,
  • the activation of the actuator 126 may be effected, for example, by the primary control device 122 and triggered, for example, after the reception of an identification signal of a special transponder, by which the system 100 is signaled that an authorized person wishes to open the knob 120 for maintenance purposes, for example.
