Definitions

  • the invention relates to an electronic locking system with at least one electronic locking mechanism and a master element having an energy source and an electrical circuit, as well as a passive transponder for controlling the electronic locking mechanism, with each between the electrical circuit and the passive transponder and between the electrical circuit and the electronic Blocking mechanism transmission lines for the exchange of data and electrical energy are formed.
  • Such an electronic locking system is for example from the EP 2 905 752 A2 known.
  • the portable transponder is arranged as a passive key without its own power source and the locking mechanism is arranged in a lock cylinder with its own power source.
  • the master element is designed as a so-called active key with an integrated energy source.
  • One of the interfaces of the master element is designed for the passive, externally stimulated output of data and a second interface for the active exchange of data with the locking mechanism.
  • the locking mechanism can be supplied with electrical power from the power source of the master element.
  • the activation of the locking mechanism requires a locking authorization contained in the integrated memory of the master element. Direct control of the locking mechanism with the locking authorization of the portable transponder is not possible. Storing a locking authorization in the memory of the master element represents an additional security risk.
  • a locking system has become known in which locking authorizations of an immobile database are transferred to an active key via a mobile computer.
  • the active key is then able to carry the locking authorizations into the locking mechanism without a data connection to the database.
  • the active key has an energy store to supply the locking mechanism with electrical current.
  • the locking system can then be closed with passive keys.
  • the known prior art has the disadvantage that if a power supply to the portable transponder or the locking mechanism fails, the data from the portable transponder cannot be used directly to control the locking mechanism. If an active key according to the state of the art is used to control the locking mechanism, it must ensure the power supply of the locking mechanism and contain all data for its control in a memory.
  • the invention is based on the problem of developing an electronic locking system of the type mentioned at the outset in such a way that communication between two passive elements is made possible without intermediate storage.
  • the passive transponder is integrated in the master element, the passive transponder and the electronic locking mechanism are simultaneously supplied with energy via the transmission paths and the electrical circuit functions as a bidirectional modulation converter which converts an input signal with a modulation scheme into an output signal with a different modulation scheme and thus enables direct communication between the integrated passive transponder and the electronic locking mechanism.
  • the master element enables the use of a passive electronic locking mechanism with a passive transponder. This avoids the temporary storage of the access authorization in a memory of the master element. In this way, querying the locking authorization is safer and faster.
  • the passive transponder and the locking mechanism can only send their data in a load modulation in order to obtain a power supply via this communication path at the same time.
  • the data can only be received in a different modulation, such as what is known as Amplitude Shift Keying (ASK) modulation.
  • ASK Amplitude Shift Keying
  • the master element can therefore be used to operate the locking system without an additional power supply. This is particularly advantageous in the event of an unexpected power failure of an electronic locking mechanism.
  • the master element can also be used as a passive identification means. In this case, the integrated passive transponder can draw its energy from the locking mechanism and works in a so-called Card Emulation Mode (CEM).
  • CEM Card Emulation Mode
  • the master element can be produced cost-effectively if the electrical circuit is designed as an integrated circuit. This design allows the process conditions during manufacture to be controlled well and manufacture as such can be easily automated.
  • the master element can be operated particularly energy-efficiently if the electrical circuit is designed as an application-specific integrated circuit (ASIC).
  • ASIC application-specific integrated circuit
  • the master element can be designed to be particularly variable if the electrical circuit is designed as a field programmable gate array (FPGA).
  • the electrical circuit can also be programmed as an integrated circuit for other tasks or, depending on the changed requirements, modifications can be made to the electrical circuit by programming. For example, the various modulation schemes that the electrical circuit converts into one another can be changed afterwards.
  • the passive transponder can be integrated into the master element particularly easily if the transmission path between the electrical circuit and the integrated passive transponder is based on RFID technology.
  • the passive transponder can be integrated into the master element in a particularly reliable and tamper-proof manner if the transmission path between the electrical Circuit and the passive transponder is a direct electrical connection. Due to the direct electrical connection, no RFID field is required for communication between the transponder and the electrical circuit, which via an external radio connection offers the possibility of intercepting the communication.
  • the direct electrical connection can be established, for example, by a cable connection.
  • the locking system is particularly easy to operate if the transmission path between the electrical circuit and the locking mechanism is based on RFID technology.
  • RFID technology As a result, no direct connection in the form of an electrical contact has to be established between the portable master element and the mostly stationary locking mechanism, which makes handling easier.
  • several forms of locking mechanisms can be addressed via RFID communication.
  • Electronic locking mechanisms designed as locking cylinders can communicate with the master element via RFID, as can electronic locking mechanisms, which are designed, for example, in the form of a simple RFID card reader.
  • the functionality of the electronic locking system can be increased in that the locking system has at least one additional passive transponder which is arranged in a passive identification element.
  • the passive identification element can for example be designed as a passive user key of the electronic locking system. In principle, however, other passive identification elements, such as identification cards, are also conceivable here.
  • additional transponders the locking system can be operated by several people with different access authorizations.
  • the functional scope of the electronic locking system in general and of the master element in particular can be increased if the master element has an interface for connection to the additional passive transponder.
  • This connection is advantageously created via RFID.
  • the interface consequently comprises an antenna for establishing an RFID connection with an additional passive transponder.
  • the entire electronic locking system can also be conveniently operated in the event of a power failure if the electrical circuit enables direct communication between the additional passive transponder and the locking mechanism.
  • the additional passive transponder which contains, for example, the locking authorization for an electronic locking mechanism that is affected by a failure of its energy source, can communicate directly with the locking mechanism via the master element and transmit its locking authorization. This communication is analogous to the communication of the integrated passive transponder. This avoids temporary storage of locking authorizations, which makes all communication safer and faster.
  • the integrated passive transponder does not have to transfer any locking authorization for the locking mechanism to be actuated, which keeps the administrative effort to a minimum in such a case.
  • the electronic locking system can be managed with as little effort as possible if the master element has a non-volatile memory for programming commands. Programming commands for assigning access authorizations can thus be stored in the memory of the master element. This allows the master element to be used as a programming unit for the locking system. An additional mobile programming element that communicates with the locking mechanisms and identification means or a network of the locking system with a central programming unit is therefore not absolutely necessary.
  • Figure 1a shows a locking system with an example of an electronic locking mechanism 2, which is designed as a lock cylinder, and a passive identification element 9, designed as a key. Furthermore, the locking system has a master element 1 in a key shape.
  • the electronic locking mechanism 2 has a locking unit 12 with a control unit 22, an antenna 21 and an energy source 24.
  • the control unit 22 is connected to an electronic memory 23 for locking authorizations.
  • a passive transponder 8 is arranged in the passive identification means 9 and connected to an antenna 24.
  • the master element 1 has an energy source 3 and an electrical circuit 4 and has an integrated passive transponder 5.
  • the master element 1 has two antennas 25, 26, the antenna 26 being assigned to the interface 10. The antennas 25, 26 are used to transmit energy and data.
  • an electronic memory 11 is arranged in the master element 1.
  • the electronic locking mechanism 2 Because the electronic locking mechanism 2 has its own energy source 24, it can be controlled directly with the passive identification medium 9 in an operating mode corresponding to normal operation. In this case, data are exchanged between the passive transponder 8 of the passive identification medium 9 and the control unit 22 in the electronic locking mechanism 2, and the locking unit 12 is unlocked if a locking authorization is present.
  • the integrated transponder 5 of the master element 1 can also interact with the electronic locking mechanism 2 to control the locking unit 12. In this case, the master element 1 works in a so-called card emulation mode. In this way, the electronic locking mechanism 2 can be controlled both with the master element 1 and with the passive identification means 9 if the locking authorization is present.
  • the power storage 3 and the interface 10 of the master element 1 are in this, in Figure 1a shown, use inoperable.
  • the electrical circuit 4 forwards the signals it receives on both sides to the electronic locking mechanism 2 and passive transponder 5 without changing the modulation schemes of the signals.
  • the master element 1 behaves like the passive identification means 9.
  • the options for exchanging data are indicated by a double arrow.
  • the direction in which an RF field is generated to transmit the energy in the direction passive identification means 9 or master element 1 are marked with a single arrow.
  • the electronic locking mechanism 2 behaves like a passive component.
  • the operating mode corresponding to this operation is in Figure 1b shown.
  • the now passive electronic locking mechanism 2 cannot be controlled directly with the passive identification means 9 because none of the components can generate the energy to generate the RF field.
  • the master element 1 with its own power source 3 and the two antennas 25, 26 enables the electronic locking mechanism 2 and the passive identification means 9 to be excited simultaneously.
  • the directions of the transmission of the energy are indicated by simple arrows.
  • the electrical circuit 4 in the master element 1 enables the exchange of data, marked with a double arrow, between the passive transponder 8 of the passive identification means 9 and the electronic locking mechanism 2.
  • the integrated passive transponder 5 of the master element 1 and the electronic locking mechanism 2 are inoperative is closed with the data of the passive identification means 9.
  • the master element 1 serves exclusively as an energy source and for the transmission of the data between the passive identification means 9 and the electronic locking mechanism 2.
  • the electrical circuit 4 converts the modulation schemes of the signals received on both sides, because both Passive identification means 9 and the now passive electronic locking mechanism 2 can only send data via load modulation in order to receive energy via this modulation.
  • the passive elements can only receive data via another modulation scheme, which is based on amplitude modulation, for example.
  • the modulation scheme used in the illustrated embodiment according to the invention is an amplitude shift keying (ASK) modulation.
  • ASK amplitude shift keying
  • the integrated passive transponder 5 of the master element 1 has locking authorization for the electronic locking mechanism 2 to be actuated, the integrated passive transponder 5 can directly assume the role of the passive transponder 8 of the passive identification means 9 in the communication.
  • This operating mode is thus similar to that described above, except that the locking authorization of the transponder 5 in the master element 1 is accessed directly instead of an additional transponder 8.
  • the master element 1 can be used as a programming unit for the electronic locking mechanism 2.
  • the master element 1 transmits the programming commands for assigning access authorizations from its memory 11 to the memory 24 of the electronic locking mechanism 2.
  • the master element 1 is preferably supplied with electrical energy by the electronic locking mechanism 2.
  • Figure 2 shows the interaction of the components of the locking system in locking operation for the case that the electronic locking mechanism 2 does not have its own, intact energy source 24 and for the case that the electronic locking mechanism 2 has its own, intact energy source 24.
  • the direction of a power supply is, analogous to Figure 1a and Figure 1b , indicated with large arrows.
  • the transmission of data or signals is indicated with dashed arrows.
  • the case with an existing, intact energy source 24 is shown with dashed arrows and the case without an intact energy source 24 is shown with solid arrows.
  • the master element 1 in the electrical circuit 4 has an interchangeable element 13 and has individual modulation and encoder units 15, 18, 19 and individual demodulation and decoder units 16, 17, 20.
  • the interchangeable element 13 has a connection to each modulation and encoder unit 15, 18, 19 and to each demodulation and decoder unit 16, 17, 20.
  • the two outputs of the demodulation and decoder units 16, 17 and the two inputs of the modulation and encoder units 18, 19 are connected to the interchangeable element 13.
  • the input of the modulation and encoder unit 15 is connected to the interchangeable element 13, as is the output of the demodulation and decoder unit 20.
  • the interchangeable element also contains a switch 14.
  • the modulation and encoder units 15, 18, 19 modulate and encode one on their Input incoming signal, on the one hand to ensure that the receiver following you receives the signal in a suitable modulation scheme and to continue to ensure a safe and efficient data transmission.
  • the demodulation and decoder units 16, 17, 20 receive a signal of corresponding modulation and coding at their input and convert it into a signal which is forwarded to the corresponding modulation and encoder units 15, 18, 19 for renewed modulation and coding.
  • the modulation and encoder unit 15 has an output on the transponder side and thus conducts either data to the integrated transponder 5 or the additional transponder 8. Since these transponders are always passive elements, they receive data in a modulation scheme that is not load modulation.
  • the signals from the modulation and encoder unit 15 are ASK-modulated.
  • the demodulation and decoder unit 20 has an input on the transponder side and is therefore used to demodulate a load-modulated signal.
  • the units 15, 20 on the transponder side are each connected to one of two possible units 16, 17, 18, 19 on the locking mechanism side.
  • a modulation and encoder unit is connected to a demodulation and decoder unit.
  • the demodulation and decoder unit 16 is used when the electronic locking mechanism 2 does not have its own, intact energy source 24 and receives a signal from this. This unit 16 therefore has to demodulate a load-modulated signal.
  • the demodulation and decoder unit 17, on the other hand, is used when the electronic locking mechanism 2 has its own, intact energy source 24. In this case, the electronic locking mechanism 2 sends its signal in an ASK modulation, which is demodulated by the unit 17.
  • the modulation and encoder unit 18 is supplied with a signal by the interchangeable element 13 if the electronic locking mechanism does not have its own, intact energy source 24.
  • the unit 18 must therefore provide an ASK-modulated signal so that the electronic locking mechanism can be supplied with energy during data exchange.
  • the modulation and encoder unit 19, is used when the electronic locking mechanism 2 has its own, intact energy source 24. In this case, the electronic locking mechanism 2 provides the energy for the communication and therefore receives a load modulation which is provided by the modulation and encoder unit 19.
  • the transponder-side modulation and encoder unit 15 is connected to one of the locking mechanism-side demodulation and decoder units 16, 17 and the transponder-side demodulation and decoder unit 20 is connected to one of the locking mechanism-side modulation and encoder units 18, 19.
  • the switch 14 and thus the interchangeable element 13 are in a setting which is intended to ensure the energy supply of the electronic locking mechanism 2 via the master element 1.
  • two transmission links 6, 7 are shown.
  • the transmission path 6 is arranged between the integrated passive transponder 5 and the electrical circuit 4.
  • the transmission link 6 forms a connection between the interface 10, which in the Master element 1 is arranged, and the electrical circuit 4.
  • the interface 10 has the antenna 26, which is used for communication with the passive identification means 9.
  • the transmission path 6 is a direct electrical connection, which can be established, for example, via cables.
  • the transmission link 7 connects the master element 1 to the electronic locking mechanism 2.
  • the transmission link 7 is implemented using RFID technology.
  • the antennas 21, 25, which are necessary for this RFID-based transmission path, are shown in FIG Figure 2 not explicitly shown for better clarity. Both transmission links 6, 7 enable the transmission of data and energy.
  • a non-volatile memory 11 is also built into the master element 1. Programming commands or event logs, for example of locking events, can be saved in this.
