Definitions

  • the invention relates to an electronic locking system with means for forming diverse hierarchies of locking authorization, the locking system having a lock with a mechanical locking device in particular and an electronic control device in particular and further consisting of an electronic key that cooperates with the control device in detail
  • Control device and electronic key are each designed to carry out the same sequence of programmable or selectable operations that form an access code on the basis of operands which can be input when a locking operation is initiated by coupling the key to the assigned lock.
  • the key and lock are designed to have at least one assignment area for storing an access code.
  • One assignment area of the key has the function of a conventional key and another assignment area another conventional key or optionally a central locking function in a hierarchy level. Further assignment areas of a key can correspond to further conventional keys on a key ring or further hierarchy levels.
  • the invention has for its object to develop a particularly simple and universally applicable electronic locking system according to the generic term so that it corresponds to high security requirements, especially with regard to reprogramming.
  • the solution to the described problem consists in an electronic locking system according to claim 1.
  • a lock or key carrier for a security code for example a card
  • the lock or the key can be additionally assigned to a programming device by means of appropriate precautions, the security code of the wearer is part of the basis for changing the access code of the locking system.
  • the locking operation itself is carried out by coupling the key to the associated lock, for example by placing the key on the lock at a designated point.
  • An access code is understood here as a work code that embodies the authorization to lock.
  • the access code is stored in at least one assignment area per key and in one assignment area per lock.
  • the access code cannot be changed without special carriers for a security code assigned to the lock or key.
  • the security code is to be inserted, for example, into a programming device designed as a service device on a card and the same security code is also stored at the lock.
  • An assignment area of the key fulfills the function of a conventional key and another assignment area can correspond to another conventional key or alternatively fulfill a central locking function in a hierarchy level. Further assignment areas of a key can correspond to further conventional keys, for example on a key ring or further hierarchy levels.
  • the electronic locking system is particularly convenient because the locks can be easily reprogrammed by the authorized person without the need for a bus system.
  • a conventional keychain can be replaced by a single key with multiple assignment areas.
  • Several conventional keyrings can also be replaced by a key with several assignment areas. The key does not apply because only the memory area in the key is expanded. In addition, you avoid a battery in the key.
  • the assignment areas can be easily programmed and also deleted using a programming device designed as a service device.
  • Such an access code can be stored in a non-volatile, electrically programmable memory, according to today's technical development in an EEPROM.
  • the locks can be equipped with plug-in modules, each of which carries a security code and can hold an access code. In the basic version, they can initially be provided with an access code.
  • the security code is advantageously only readable, according to the current state of development, for example in ROM masks.
  • Such a security code is advantageously arranged on a carrier which, in addition to an access code, can also contain an identifier for an assignment area.
  • the hierarchical organizations can be prepared by the manufacturer by assigning corresponding or different security codes under the same assignment areas and by correspondingly providing locks with the assigned security code. This can be done on carriers that are inserted or attached to the lock in a modular manner. It is advantageous if the lock supports for carriers with security code, access code and characteristic of the assignment area.
  • a device for delivering an identifier for the assignment area is provided at the lock, which, when coupled with the key, leads to the search for the corresponding assignment area. This avoids a repeated search in the lock, which would have to be triggered by the key until the assignment area is found in the lock, which matches the corresponding assignment area of the key.
  • a flat coil can be attached in a region designated on the door, which is used for energy transmission and data exchange to the key.
  • the data transmission can advantageously take place in "frequency shift key", FSK, or in frequency modulation, FM, and can be operated in handshake mode. This eliminates the need for a battery in the key, since in the meantime alternating acknowledgment charging can electromagnetically transmit energy to a memory in the key, which ensures that the computer is supplied in the key.
  • the means for recognizing the coupling can advantageously work with pulses, in particular needle pulses, the damping of which serves as a criterion for a present coupling.
  • Securing keys which are handed over to children, can be achieved according to a further development in that the key is attached to a tether that is to be attached to a child's wrist if the access code is designed in such a way that when the tether is opened for the key is destroyed.
  • an intended opening point can be secured against impairment of the code by a supplementary device, to which contact can be made by the tether, so as not to destroy the access code when the tether is authorized to be opened.
  • a key can be called a self-deleting key.
  • the control device of the lock carries out operations on the basis of an access code if the assigned key is coupled at the intended location.
  • the core part of an access code is stored in a field.
  • an access code can consist in each case of a core part 1 or 1 ', etc. and consist of operands which are formed by a random generator in the control device of the lock.
  • the core part can be a memory field in which computing algorithms are stored.
  • the control device of the lock On the basis of the damping of a test signal, the control device of the lock is brought into the activated state, the energy store of the key is charged by the control device of the lock by inductive coupling via the coupling coils and a sequence of programmable or selectable operations on the basis of determined or specified operands and on the basis of the core part 1 of the access code in the assignment area 4 of the lock on the one hand and of the access code in the assignment area 5 of the key.
  • the energy store of the key can be charged at intervals between the arithmetic operations.
  • the computational algorithms in the core part, for the operations and for the sequence of operations can be stored in a non-volatile, electrically programmable memory, as of today in an EEPROM.
  • a number of arithmetic operations can be varied in the result by selecting specific operands.
  • these operands can each be new in the control device of the lock with the assignment area 4 formed and communicated to the assignment area 5 of the key.
  • the arithmetic operations, the arithmetic algorithms, in the assignment area 4 in the control device of the lock and in the assignment area 5 in the control device of the key then run with these selected operands as the access code.
  • the result determined for the key is fed to the lock via the communication line 6 and compared with the result for the lock. If there is a match, the lock or its locking device is actuated and opened by means of its energy store. This can be understood to mean that the door can then be opened by hand or that a bolt is automatically withdrawn.
  • An access code can also be formed by making a selection from several computing algorithms using operands. These operands can again be generated in a random generator.
  • an identifier, a word or a number is also stored in the assignment area 5 of the key as the area number with the reference symbol 2.
  • the corresponding area number 2 is also stored in the assignment area 4 of the lock.
  • the area number 2 of the assignment area 4 is fed via the control line 7 to the field with the area numbers and there to the corresponding area number. This avoids running through all access codes in the key. Otherwise, if another access code is stored in the key in the first place during the search, the operation with the computing algorithm will deliver a different result than for the assignment area 4 of the lock. If the assigned access code is finally found in the key, the results match and the lock is opened.
  • a device at the lock for issuing an identifier for the assigned core part of the access code is provided in such a way that, when coupled with the key, it immediately leads to the search for the corresponding core part, so that the search over all fields with core parts is avoided. This can significantly shorten the closing process.
  • a security code 3 is also stored in the assignment area 4 of the control device of the lock.
  • the security code can be stored in a read-out memory, a ROM. It ensures that a recoding of the lock is only possible with a programming device 8 designed as a service device if the security code 3, with its ROM mask, the programming device corresponds with the security code 3, or the ROM mask, of the lock.

  • the programming device 8 can reprogram the assignment area 4 in the control device of the lock with its core part 1 of the access code or else the access code.
  • a calculation algorithm can be generated by the generator 10 of the programming device 8, which is based on the Carrier 9 of the core part 1 of the access code is stored and transferred to the assignment area 4 of the lock as core part 1 of the access code.
  • the security code 3 of the carrier cannot be changed.
  • the programming device 8 with the inserted carrier 9 in the assignment area 4 of the lock can find the assigned area number 2 and via the communication line 6 a comparison can be made with regard to the security code 3 between the carrier 9 and the assignment area 4 of the lock.
  • the core part of the access code 1 can be reprogrammed in the assignment area 4 of the lock via a working line 11.
  • the lines 6, 7 and 11 can be understood as paths of a communication route. This can in particular be designed as an inductive transition path.
  • the corresponding area number 2 can be found in the assignment area 5 of the key by the programming device 8 when the carrier 9 is inserted via a control line 7 and the core part of the access code 1 can be reprogrammed via a work line 11.
  • the area number can be indicated by a pointer 12.
