Definitions

  • the invention relates to a wear-free programmable electronic locking device, in particular for doors with changing locking authorization.
  • locks with fixed keys are provided for doors with changing locking authorization, for example for doors of swimming pool cabinets, the keys stuck in unused cabinets in waiting position in the locks. If a cabinet is occupied, the lock is actuated and the operator takes the key with him.
  • the prior art ( DE 44 15 104 A1 ) include a method and apparatus for storing data in a portable storage device having nonvolatile memory writable and readable by a controller having a writing and reading device.
  • a controller having a writing and reading device.
  • the controller has a random generator for generating a random code as an identifier and a memory for storing a random code.
  • the random code can also be transferred to the memory unit and stored in its non-volatile memory. From the memory, the random code can be read again after interruption and after restoration of the optical coupling and optically transmitted back to the control unit.
  • the control device has a device for comparing the random code stored in its memory with the random code returned by the memory unit, which is coupled to an evaluation device.
  • This device may be provided, for example, to release the reading mechanism of the locking system, so that opening of the locking mechanism is only possible if in the memory of the memory unit, the same random code as stored in the memory of the control unit.
  • This belonging to the prior art locking device has the disadvantage that with the memory unit that is used as a key, for example, several locks a locking system can be operated so that with a key, for example, several cabinets, for example, in a swimming pool, can be occupied.
  • the prior art also includes a locking system, which additionally has a cryptography unit, and in which a remote control unit is used as an electronic key.
  • This belonging to the prior art device has the disadvantage that several locks can be actuated with an electronic key.
  • the technical problem underlying the invention is to provide a locking device in which the assignment between the key and lock during or immediately before the actual closing takes place, with a free choice between the locks to be operated should be guaranteed, and is ensured in the that with a key after pressing a lock no other lock is actuated, the locks work completely self-sufficient.
  • the locking device consists of an electronic read / write key and an electronic programmable lock.
  • This locking device is based on the principle of non-contact, electromagnetic code and locking data transmission between a passive electronic key and an active electronic lock.
  • the electronic lock and the electronic key do not necessarily have a permanently associated locking authorization, since the assignment of locking authorization between electronic lock and electronic key until the moment of closing by means of non-contact bidirectional data transmission between active electronic Lock and passive electronic key.
  • the disadvantage of the known systems namely, that multiple locks are actuated with a key, thereby prevented that is locked due to the stored state data in the key after a closing of the key for further closing operations.
  • Areas of application of the locking device according to the invention can be found everywhere where a frequent change of locking authorization must be made, as is the case for example in hotel doors and lockers in leisure facilities.
  • the locks of the locking device according to the invention operate independently and independently of a central unit, that is, the locks are completely self-sufficient.
  • the locks are each operated and parameterized with the key, for example a lock card, without the locks being in contact with each other or being controlled by a central unit.
  • a lock can be selected with any key, which is not yet closed.
  • the castle requests the closing authorization identifier and the closing status of the key. Subsequently, a check is made of the closing status received by the key and a decision is made as to whether it is an authorized key that has not yet closed another lock. If the authorization of the key is ensured, the closure takes place. After the closure is performed, the lock status and the lock ID are transferred from the lock to the key. There, the data is stored in the data memory. At the same time, the locking authorization identifier of the key and the locking status are stored in the data memory of the lock.
  • the key is returned to bidirectional, non-contact contact with the lock.
  • the lock queries the lock authorization identifier and the lock status of the key. Subsequently, a check is made on the closing authorization identifier and the closing status of the key and a decision is made as to whether it is the key that last locked the relevant lock.
  • the unlocking of the castle takes place.
  • the lock status of the lock is transferred from the lock to the key and checked in the key. If the result of the test is positive, the data in the data memory of the key is deleted. At the same time, the locking authorization identifier of the key in the memory of the lock is deleted.
  • a clock is arranged in the lock, preferably with date and time.
  • the clock can also be designed in the manner of a stopwatch.
  • the time and / or date is stored in the memory of the lock. After a predetermined period of time, for example when the residence time in the leisure facility has been exceeded, the lock can no longer be actuated with the key associated with the closing operation.
  • the stopwatch is started during the closing process.
  • An opening operation with the associated key is then also allowed only in a predetermined period, for example within two or three hours.
  • the predetermined period is stored in the key. During the closing process, the period is transferred to the lock with the other data, with the lock, as already stated, can not operate after this period.
  • the locking device gains in security, since in the case of the removal of a key, the lock in question can not be opened beyond a certain period of time.
  • visitors, such as a swimming pool thereby caused not to exceed the use of the swimming pool, without having to make a back payment for example.
  • the locks and / or the keys are battery operated. They have one or more accumulators. Since the locks according to the invention operate independently and independently of a central unit, it may happen that the battery or the accumulator are empty, so that the lock has no power supply and can not be operated. For this reason, the locking device according to the invention has an emergency power supply.
  • the emergency power supply is designed such that via the transmitting and receiving device of the lock, an inductive power supply of the castle can be done by the key so that the lock operated at least once, for example, can be unlocked.
  • the keys can advantageously also be provided with the inductive power supply.
  • Fig. 1 shows a locking device (1) with an active electronic lock (2) and a passive electronic key (3).
  • the active electronic lock (2) consists of the components data memory (4), in which the closing data and the closing authorization or the identification are stored, the transmitting and receiving device (5) with connected transmitting and receiving antenna (6), whose job it is , the non-contact communication with the passive electronic key (3) to perform, and the control device (7), which checks the data received via the transmitting and receiving device (5) for plausibility and accuracy and stores in the data memory (4) with a positive test result , Sends response data to the transmitting and receiving device (5) to send to the electronic key (3) and transmits commands to an input / output unit (8).
  • the task of the input / output unit (8) is the control of the digital outputs, signaling of operating states, the control of an actuator (not shown) for closing and opening a closed by the locking device (1) door (not shown) and the reading of digital inputs to determine the current closing state.
  • the passive electronic key (3) consists of the components data memory (9), in which in addition to the closing data and the variable locking authorization identifier is stored, the transmitting and receiving device (10) with connected transmitting and receiving antenna (11) and coupled energy storage (12 ), whose task is the non-contact communication with the electronic active lock (2), and the control device (13) which checks the data received via the transmitting and receiving device (10) for plausibility and correctness and, if the test result is positive, into the data memory ( 9) or transfers response data to the transmitting and receiving device (10) to send to the electronic lock (2).
  • Fig. 2 is to protect the traffic between the active electronic lock (2) and the passive electronic key (3) against copying, falsifying or copying all relevant for the closing process data in the lock (2) and in the key (3) each have a cryptography unit ( 14, 15) are provided.
  • the electronic lock (2) has a clock (16).
  • the control device (13) of the key (3) is a certain period, for example, stored by two hours. This period is transferred during the closing process on the lock (2).
  • the data memory (4) of the lock (2) the time is stored, from which the stored in the key (3) period is exceeded.
  • Fig. 4 shows three electronic locks (17, 18, 19) and two electronic keys (20, 21), wherein the electronic locks (17, 18, 19) are not in communication with each other or to a parent unit.
  • the locks (17, 18, 19) are in an unlocked condition. With the key (20) one of the locks (17, 18, 19) can be selected, for example, each a locker door in the swimming pool to close with the key (20) the selected lock.
  • the closing state data is exchanged, such that with the key (20) no further lock (18, 19) can be closed after the closing operation. It can also with the other key (21) the lock (17) are not actuated, as long as the assignment between the key (20) and the lock (17). With the key (21) only a selection between the locks (18, 19) can be made.
