Definitions

  • the invention relates to a method for setting up an electromechanical lock.
  • Electromechanical locks exchange data with corresponding keys, either in the lock and / or in the key, the exchanged data are processed to verify authorization of the key. Depending on the result of the check, the lock releases a permission, e.g. access to a place secured by the lock, or the possibility of locking a door.
  • Electromechanical locks are often realized as so-called wireless locks. These radio locks communicate via a radio link with so-called radio keys and thus enable a non-contact authorization check.
  • the radio key can be a passive transponder, for example, which is held in front of a radio lock and then read out by it.
  • the distance between the radio key and the radio lock is usually only a few cm (about 0 - 50cm).
  • the radio key may have an active transmitter, which sends a signal after actuation of a button, which is received and evaluated by all radio locks in the transmission range of usually a few meters (about 0.5m - 50m). This type is called an active radio key.
  • This system has the advantage that the radio key can be actuated and the radio lock released when approaching the radio lock.
  • the gateway control unit can receive data from a server via a radio data link and is connected via at least one vehicle bus to a plurality of control devices of the vehicle in order to apply new program codes to the control units via software download or remote flashing.
  • the gateway controller can be freely configured for this. Shortened formulated, the gateway control unit is configured via a radio data link so that the gateway control unit then serves as a programming device for a control unit.
  • DE 197 01 740 A1 describes a "Keyless Go" locking system for a motor vehicle.
  • the locking system has a key in which a first relatively long code is stored, which is queried by the immobilizer and this switches if necessary free.
  • this key has a second shorter code that is correspondingly fast to transfer and is requested to unlock the door.
  • the codes are transmitted encrypted as usual. The selection of a corresponding code is made by the respective "lock” and either by a precommand or by the length of a random number transmitted by the lock, which is encrypted by means of the corresponding code and then transmitted back to the lock.
  • DE 101 38 217 A1 proposes, in a communication between a transponder and a base station, the header of the data packets information about the data transmitted in the middle section of the data packets, eg their identifier to specify.
  • WO 2010/039598 A2 It is believed that prior art electronic locks communicate with each other over a common network and then be configured over that network. Alternatively, the access control devices can be individually configured directly. These two ways of configuring locks are considered either too hardware-intensive or error-prone. Therefore, it is proposed to visit each lock individually and to bring by a smart card in a learning mode. In the learning mode, the lock communicates with a PDA via a wireless data link. By means of the PDA, the lock is integrated into a closed position and taught accordingly.
  • EP 1 8035 436 A1 suggests a transponder reader that can handle different protocols to communicate with different transponders. When programming a transponder in a programming mode, these protocols are tried out in order. If a transponder reacts to a specific protocol, then the transponder type and a transponder identification are queried. This is then stored in the transponder reader.
  • WO 00 55 796 describes very abstractly a communication method between a reference system and a reader.
  • the reference system transmits information to the reading system to optimize the transmission speed.
  • US 7,075,412 B1 is based on the observation that the protocols for the communication of RFID tags with the corresponding readers are constantly evolving. This requires a regular replacement of the readers. To avoid this, the software is probably adapted as a firmware update to the new RFID tags.
  • WO 2008/144804 discloses an access control device configured by means of a "Commisioning" card. In this configuration, a device ID and encryption key are transferred from the smart card to the device.
  • the invention is based on the observation that there are a large number of providers of electromechanical locking systems whose components are not interchangeable or combinable with each other, although they use identically designed remote control keys, which are e.g. come from a common supplier or are standardized. If one has opted for a locking system of a first provider, the locking system type is set and you can not later integrate a lock from another provider in the then existing locking system, i. usually do not share with the already existing keys of the first provider and / or lock and / or add them to existing lock groups.
  • the invention has for its object to provide a method with which electromechanical locks of different manufacturers can be integrated into a locking system.
  • the invention is based on the recognition that a lock of a first manufacturer could theoretically communicate with keys of a locking system from another manufacturer, but that this fails in practice because the manufacturers use different communication protocols. These communication protocols are previously coded in the respective firmware locks and thus after delivery no longer or only with large Effort changeable.
  • the invention is based on the recognition that the communication protocols used can be parameterized between a lock and a key. Therefore, it is sufficient for a lock to transmit the information about the parameters of the communication protocol used within a particular type of locking system so that it can henceforth communicate with these parameters and thus with other components of the corresponding locking system type. A complicated firmware update can therefore be omitted if a lock is to "learn" the communication protocol used in a locking system type.
  • the method of setting up an electromechanical lock has at least two steps; namely, as a first step, transmitting at least one parameter from a first data carrier to the lock after a first communication protocol, and as a later step determining at least one second communication protocol from the parameter transmitted after the first communication protocol.
  • a lock can be adapted, as it were learned, by transmitting information necessary for communication between components of a specific locking system type to this specific locking system.
  • Typical components of a locking system are usually programmable keys and locks and usually also programming devices. It is therefore sufficient to provide a first communication protocol by means of which the parameters of at least one locking system type, that is to say the parameters of a second communication protocol, can be transmitted to the lock and / or at least one key.
  • the lock After the transmission of the parameters of the second communication protocol, the lock can be adapted to a specific locking system type, this can be triggered, for example, by the transmission. Subsequently, the lock can be integrated, for example, in an existing locking system of this type of locking system. The installation of a manufacturer-dependent firmware is not necessary to adapt to the locking system type.
  • the transmitted parameters ensure that the data transmitted according to the second communication protocol can be correctly interpreted by the lock.
  • information about the second communication protocol is transmitted in a metalanguage, namely the first communication protocol to the lock, which then determines an object language, namely the second communication protocol, from the information transmitted in the metalanguage.
  • the object language may include communication patterns, eg, the length and structure of frames exchanged according to the second communication protocol, the data rate of the second communication protocol, as well as information about data formats for information to be transmitted according to the second communication protocol, eg date and / or time information or to be used encryption algorithms.
  • a metalanguage in which the second communication protocol can be defined can be, for example, XML or a similar language.
  • the metalanguage can also be used to determine a physical interface, more generally a port of the second communication protocol, for example a specific transmission and / or reception frequency, an antenna or a connection.
  • a communication according to the first communication protocol is handled via the same physical interface or the same port as the communication according to the second communication protocol.
  • the first communication protocol preferably uses as well as passive RFID transponders the attenuation of an electromagnetic field emitted by the lock to the at least one parameter after the first Transfer communication protocol.
  • the at least one parameter can be stored, for example, in an RFID transponder and transmitted after the first communication protocol.
  • the second communication protocol may provide for transmission by attenuation of an electromagnetic field emitted by the lock, but the first communication protocol may be transmission by means of a frequency modulated electromagnetic wave or by means of a cable connection.
  • the method can be used for all communicating components of a locking system, i. not only used for locks. So it is strictly speaking a method for setting up a component of an electromechanical locking system. Only for the sake of clarity, the invention will be explained using the example of a castle.
  • the component ie the lock, generates the second communication protocol after transmission of the parameters. it has all the information to exchange data with other components of the locking system type determined by the second communication protocol. Exchanging data may be, for example, performing an authorization query. The result may also be that a key (as a synonym for another component) does not have the necessary authorization.
  • information about the authorization of keys of a particular locking system is transmitted to the lock according to the second communication protocol.
  • tools tools
  • a lock would be made with firmware containing the first communication protocol.
  • the lock could then be delivered to a middleman.
  • the intermediate trailer can then transmit the parameters by means of the first communication protocol on the basis of which the lock determines the second communication protocol.
  • the lock can be integrated into a locking system, for example by transmitting information about authorized keys according to the second communication protocol.
  • the authorization check is performed such that a secure, i. encrypted data link between the communication partners is established.
  • so-called crypto-keys are used, which are values to be kept secret, by means of which the data to be transmitted is encrypted and / or decrypted. If the crypto-keys of two communication partners do not match, no secure data link can be established; Nevertheless, the communication partners communicate with each other, because they are able to exchange the data necessary for setting up the secure data link through the second communication protocol. This exchange is also initiated correctly, but the authorization check is aborted because the check of the crypto-keys reveals that they do not match.
  • the cryptokey is not included in most locking systems to the parameters of the locking system type, but most of the encryption algorithm. However, the encryption algorithm can also be specified by a standard and is then preferably stored in the hardware or firmware.
  • the parameters of the second communication protocol are usually not the information associated with a particular object or building (hereinafter "object-specific information”), such as the lock facility number or membership of a component to a particular lock group, but the information necessary to be object specific To read and / or write information, if authorized.
  • object-specific information such as the lock facility number or membership of a component to a particular lock group
  • the term parameter in one embodiment of the invention does not necessarily designate the commands available for the communication, it preferably designates at least the information necessary for the assignment of transmitted data to given variables.

  • parameter is meant any information transmitted from the volume to the lock after the first communication protocol to determine the second communication protocol.
  • data is all that is transmitted according to the second communication protocol.
  • Each type of memory can be used as a data carrier, from which the at least one parameter of the second communication protocol is transmitted to the lock by means of the first communication protocol.
  • Typical memories are magnetic memories, semiconductor memories and optical memories.
  • the lock communicates by means of the second communication protocol with at least one key.
  • the lock can therefore communicate with appropriate parameters with keys of any locking system type and thus be integrated into this lock system type.
  • At least the size of the vector spaces of the doors and / or the keys and / or the locking groups is transmitted as at least one parameter.
  • These sizes are often essential to the memory management of the castle and / or the key and for the bit length of the corresponding variables and fields, because in many locking systems in the authorization check the information is exchanged in which locks and / or locking groups of the respective key is authorized.
  • All doors, locking groups and keys of a locking system form the basis for the respective binary vector space T, G or S.
  • the dimensions of the respective vector spaces T, G, S limit the maximum number of locks, locking groups or locking mechanisms that can be integrated in a locking system of the given locking system type Key.
  • the dimension of the corresponding vector space is information about the storage space required for representing the vectors, which is relevant when extracting such vectors from a bit sequence.
  • m is the dimension of the vector space and thus indicates the maximum number of manageable locking groups in the given locking system type.
  • ⁇ and / or p and the other component, respectively, and m may be a relevant parameter to represent a vector ⁇ evaluate containing bit sequence.
  • the representation of binary vectors such as the binary vectors of the vector spaces T, G, S may be parameters of the second communication protocol.
  • a header is preferably transmitted which identifies the following information of the transmission as a parameter of the second communication protocol. This can do that Lock based on the header distinguish whether it communicates with a key or whether it is adapted to a locking system type.
  • parameters of the second communication protocol are transmitted in blocks, wherein a specific block section identifies the parameter and at least one further block section identifies the value of the parameter.
  • the block preferably contains an indication of its size. This increases the flexibility of the first communication protocol, and makes it possible to omit unnecessary parameters.
  • a preferred parameter of a second communication protocol is, e.g. the type of encryption of the lock-to-key communication, or the way in which authorizations are time-limited.
  • Another preferred parameter is the way of retrieving data from the lock or key.
  • the second communication protocol allow immediate read and / or write access to specific memory areas of the respective communication partner.
  • the jump addresses (pointers) to the corresponding memory locations are preferably parameters of the second communication protocol.
  • the information can be transmitted on how a bit sequence transmitted according to the second communication protocol is to be interpreted.
  • the values of the individual variables for checking the authorization such as a locking group number, a door number, etc.
  • the information about the positions of the values of Variables in the bit sequence are preferably transmitted after the first communication protocol.
  • At least one parameter in the lock has a standard value (default value) which can be replaced by another value when transmitting the information.
  • default value the amount of information to be transmitted can be reduced and there can be a "default protocol”. It is then sufficient to transmit the deviations of the second communication protocol to the lock.

  • data can be stored in compressed form and / or transferred.
