Definitions

  • the invention relates to a lock cylinder with contactless transmission of an authorization signal, which is provided with two opposite lock cores, each actuated by a key or by a rotary knob or by a knob or a key to actuate the locking lug for unlocking a lock, and which cooperates with an electronic decoding device, which has at least one receiver and / or transmitter for wireless transmission of a coded authorization signal and an evaluation unit for decoding the authorization signal to allow only on authorization the unlocking of the lock, which receiver cooperates with antennas, which is an authorization signal received from the key or a code card.
  • a lock cylinder which is provided with a rotary knob on both sides, is described in EP 0 999 328 A1.
  • a lock cylinder which can be actuated on one side by a rotary knob and on the other side by a key is described in DE 199 30 054 A1.
  • the arrangement is such that the rotary knob is always rotatably connected to the locking lug.
  • the housing of the lock cylinder On the side which can be actuated by the key, the housing of the lock cylinder has an antenna which cooperates with a corresponding antenna in the key.
  • a wireless transmission of the authorization signal is hereby possible.
  • DE 195 17 728 A1 discloses an electromechanically operating lock cylinder which can be actuated on both sides by a reversible key.
  • antennas are arranged in the cylinder bag in the vicinity of the lock core in order to achieve the smallest possible distance between the antenna and the antenna of the inserted key.
  • a lock cylinder which can be actuated on one side by a key and on the other side by a rotary knob. On both faces an antenna is present. The one antenna always interacts with an antenna in the rotary knob for the wireless transmission of a signal.
  • WO 99/29542 A2 an arrangement of several parallel antennas is known which cause a uniform emission of signals around a vehicle and in the Innraum.
  • a switch is provided to switch the antenna groups indoors or outdoors. The antennas can also receive a signal at the same time. This works but reliable only with a single transmitter in the range of the antennas.
  • Further lock cylinders are known from EP-A-1046770 and EP-A-0743412.
  • the decoding devices are often designed as transponder systems, of which a passive transponder is arranged in the key, while the transponder reading device including the antenna, the evaluation unit and the power supply are arranged in or on the lock cylinder housing or in the rotary knob.
  • This basic arrangement has the advantage that the key itself no separate power supply is required.
  • the antenna of the transponder reading device is activated such that it excites the antenna of the passive transponder on the key or on a code card, so that the stored transponder signal can be transmitted with the authorization signal. If the authorization signal has the appropriate access code, the electromechanical lock is enabled by the evaluation unit.
  • the invention has the object of providing a lock cylinder of the type described in such a way that a secure data transmission with low energy consumption is possible.
  • the object is achieved according to the invention in that on each of the two opposite sides of the lock cylinder in each case an antenna is present, which are connected via a switch with the evaluation, the evaluation unit with due to the imported key or the operated and / or activated knob that antenna of the lock cylinder connects, which is arranged on the side into which the key has been inserted into the lock core or on which the rotary knob has been operated and / or activated.
  • a switch with the evaluation has, on the one hand, the advantage that the evaluation unit is actually connected only to the antenna which will receive the authorization signal.
  • the switch is switched between the antenna and the evaluation device or the electromotive actuator is basically arbitrary. It is especially important that a perfect release signal for driving the electromotive actuator is generated. It can be provided that each antenna. Receiver is assigned, and that the switch is connected between the receiver and evaluation. Alternatively, it is possible that the receiver comprises a signal read circuit and in particular an A / D converter whose output is connected directly or indirectly via the switch to the evaluation unit.
  • the switch is designed so that the evaluation unit is connected to that antenna of the lock cylinder, which is arranged on the side into which the key is inserted last or on which the rotary knob has been actuated and / or activated last.
  • the switch is basically arbitrary. Semiconductor circuits or else bistable or monostable relays can be provided. In particular, the provision of a relay is possible with simple means and without circuit complexity. Also, the switch can be realized by two independent inputs of a microprocessor of the evaluation, which are switched according to the activated antenna.
  • the change-over switch is switched on the basis of switching signals of switches which are actuated by the key during insertion into the lock core.
  • switches are basically known. It can be provided that the switches are designed as micro-switches, which not only activate the decoding device upon complete insertion of the key into the locking core, but also effect the required switching to the antenna to be activated.
  • the switches can also be designed as non-contact proximity switch. Since such a switch must be present on each side of the lock cylinder, an assignment is readily possible.
  • the lock cylinder has a knob, it is useful 'when the switch switches due to switching signals of switches that are actuated due to actuation and / or activation of the knob.
  • the arrangement can be made such that the rotary knob, for example, axially pressed to activate the decoding device. At the same time, the relevant antenna can be excited. It can also be provided that upon a slight rotation of the rotary knob, a switching signal is generated, on the basis of which the decoding device and the associated Antenna activated. But even here, a proximity switch, which detects the approach of a person within a certain radius, be appropriate.
  • the switches interact directly with the switch. It may also be expedient if the switches interact with the switch via the evaluation unit. Since the excitation of the antenna in the lock cylinder is accompanied by the activation of the decoding device, this embodiment, which includes a control of the changeover switch by the evaluation unit, is basically possible.
  • the switch connects the antenna with the evaluation unit for a predetermined time.
  • This predetermined time may coincide with the time that remains in operation for the decoder after activation and then shuts down to minimize power consumption. After a failed closing process, the closing process must be repeated after this time.
  • the evaluation unit which acts on the side of the lock cylinder, in which the key has been last inserted, accidental or intentional blockage of the lock is prevented by a stuck on the other side key.
  • the evaluation unit, the switch and the antennas are integrated in the lock cylinder housing.
  • a lock cylinder is provided which can be readily used in conventional locks. Complementary measures and in particular the laying of antennas and the like are not required.
  • the antennas are arranged in the region of the closing core or in the front region of the lock cylinder housing. As a result, a small distance is achieved to the antennas in the key, so that the energy required to excite the antenna of the transponder reading device can be kept low.
  • the changeover switch is connected upstream of the A / D converter of the evaluation unit.
  • the evaluation device usually comprises a microprocessor, a signal read circuit, and the antenna.
  • the signal read circuit converts the analog authorization signal received by the antenna into a digital form that can be evaluated by the microprocessor and compared with the access code.
  • the microprocessor also controls the required for the unlocking and / or operation of the lock electronic components. If the changeover switch is now switched before the A / D converter of the evaluation unit, ie before the signal read circuit, there is an advantage in that only one such needs to be present. In particular, a clean separation of the analog signals takes place. If the switch is connected behind the A / D converter, it would be necessary for such a separation to provide two signal read circuits. This would increase the installation space.
  • the key and the lock core are designed as a reversible key system. This has the advantage that such key systems for mechanical locking only need the cylindrical receptacles of the lock cylinder housing. In the lock cylinder bag, which is located below these recordings, therefore, there is sufficient space to accommodate the electronic components.
  • the lock cylinder shown in FIG. 1 has on its opposite sides 11, 12 each have a hollow cylindrical receptacle for a lock core, which is rotatable by a key in the receptacle.
  • the key comprises mechanical projections and recesses, which cooperate in the usual way with mechanical tumblers in the lock core, so that rotation of the lock core is possible only in case of agreement.
  • the key can be designed as a conventional flat key or as a reversible key.
  • the Lock core is connected to a locking lug 13 shown only schematically, which can be rotated with a matching key for unlocking a lock, not shown.

  • the lock cylinder shown has an electronic decoding device with evaluation device 20, which comprises a transponder system.
  • antennas 14, 15 which receive an authorization signal from an antenna, which is present on a key, not shown.
  • the antenna in the key may for example comprise a passive transponder, which is excited by the relevant antennas 14, 15 in the shooting cylinder for transmitting the transponder signal with the authorization signal.
  • the locking cylinder shown is actuated from both sides with an electronically coded key, and on the opposite sides 11, 12 each have an antenna 14, 15 is arranged. These antennas are preferably in the front region of the lock cylinder housing 16, so that a short data transmission distance is effected to the imported key.
  • the antennas 14, 15 are connected via a switch 17 in conjunction with a receiver with signal reading circuit 18, which preferably converts the received signals into a digital form and forwards them to a microprocessor 19 of the evaluation device 20.
  • the receiver may also be designed as a transceiver, for example, a passive transponder of a key or another mobile Encourage code carrier. Also, the signal read circuit of the receiver may be integrated in the evaluation unit.
  • the received signals are evaluated and compared with the authorization code to effect unlocking of the lock.
  • electronic control means 21 may be provided, which are controlled by the microprocessor 19 to allow, for example, with appropriate mechanical and suitable electronic key rotation of the lock core in the respective recording.
  • the motor 22, which was switched by the control means 21 and shown schematically, would then drive a blocking element.
  • a suitable mechanical and suitable electronic key a force connection between the lock core and the locking lug 13 is made. In this case, the motor 22 would drive a coupling.
  • the locking cylinder shown is in the idle state, that is, that the evaluation unit 20 is not in operation and thus has no or only a minimum quiescent current consumption.
  • the evaluation unit 20 is activated.
  • the antennas 14, 15 are activated to excite the passive transponder in the inserted key to receive the authorization signal.
  • the arrangement is such that the microprocessor 19 detects those switching 23, 24 which has been actuated by the inserted key is.

  • the evaluation unit 20 is activated, whereupon the antenna 14 is excited and ready to receive.
  • the switch 24 is actuated, whereby on the one hand the evaluation unit 20 is activated, so that the antenna 15 can excite the passive transponder in the key.
  • the switches 23, 24 interact directly with the changeover switch 17. This is shown by dashed lines in the drawing.
  • each antenna 14, 15 is assigned a receiver with signal read circuit 18, 18 'whose output is connected to the changeover switch 17.
