Definitions

  • the invention relates to an antenna system for an electronic or mechatronic lock cylinder, according to the preamble of claim 1 and to a method for operating an antenna system for an electronic or mechatronic lock cylinder, according to the preamble of patent claim 7.
  • Characteristic for locking cylinder according to DIN standard 18262 is their property bzgi. inside the cylinder mounted antennas act as Faraday cage. This feature is a major drawback to the operation of electronic launchers, which are typically to be wirelessly monitored and controlled from a central point.
  • Antennas in lock cylinders are known from various products available on the market.
  • the risk of manipulation of the radio link between the lock cylinder and central control of the operator is a high security risk. If the usually encrypted communication is intercepted and hacked, an attacker can gain unhindered access to the building. This risk has hitherto been borne by many object operators to use this comfortable and efficient form of building management. Instead, commercially available data input devices are used, with the help of which the data is laboriously transported between the central PC and the cylinders distributed throughout the house ("data spoons").
  • knobs of their electronic lock cylinders are either made of non-metallic materials or the metallic cap is used even as an antenna radiator.
  • knobs already designed as antennas for RF radio are known, see for example EP 1 908 898 A1.
  • antenna system has a serious problem.
  • the arrangement of the antenna in one of the two knobs leads to a strong directional characteristic of the transmission field or the reception properties.
  • the arrangement of the antenna in the knob of a cylinder leads to a strong radiation forward, sideways and upwards. This alignment results from the reflections of the mortise lock, the door fitting, the striking plate in the door frame and the floor,
  • two dielectrically conductive knobs which are positively and / or non-positively connected to a cylinder core, are formed directly as active antenna poles, wherein at least a part of the lock cylinder is designed as an electrical counterweight and the knobs and the electrical counterweight are arranged electrically isolated from each other.
  • At least one of the knobs directly serving as the active antenna is made of metallic material.
  • one of the knobs is made of a plastic and / or ceramic and / or glass material and is provided with an electrically conductive coating. It is not necessarily necessary that the complete knob is provided with a coating, so that partial coatings can be applied. Furthermore, at least one of the knobs may have a selectively metallized board.
  • an antenna system for an electronic or mechatronic Sch thoroughlyzyiinder which its knobs as active antenna elements for wireless communication with a remote station or a Relay station uses.
  • other locking cylinders arranged in a corridor or in the vicinity of construction with the same antenna system are the counter stations or relay stations, with connection to a superordinate surveillance or building management system.
  • the antenna system according to the invention provides that the preferably metallic knobs form the active antenna pole, while the metallic housing components store the other antenna pole, i. H. to form the counterweight. Consequently, an antenna system with a dipole character is formed.
  • the antenna system can also be operated with reverse polarization, so that in such a case the selected parts of the lock cylinder and the two knobs each change their function.
  • a circuit arrangement is provided which can activate a polarization reversal with respect to the dipole character of the antenna system.
  • the operating principle of the antenna system described above is to realize an electronics which is able to use the handles of a Knaufzylin- ders according to DIN standard as active antenna elements and thereby to generate a transmission field, which propagates spherically around the cylinder , It is thus independent of the respective door position and offers a great advantage in terms of reliability of data transmission.
  • the spherical transmission field is achieved by the use of two parallel operating antennas in the inner and outer knob, with inside and outside, for example, describe the interior or exterior of the room.
  • the two emission characteristics overlap each other in such a way that a de facto uniform "illumination" of the cylinder environment takes place.
  • the housing profile, the rotatable cylinder core and the cam together form the electrical counterweight.
  • These components of the housing are usually made of brass, stainless steel or other suitable metallic alloy. Also conceivable is the use of metallized plastics or metallized ceramics.
  • the active antenna pole is formed by the metallic knobs, which are flanged to the cylinder core as part of the electric counterweight, but must be electrically insulated from this counterweight.
  • knob cylinder according to the invention is installed according to DIN standard (eg DIN 18252) in a similar DIN mortise lock, the counterweight expands around the metallic mass of the mortise lock and also of the door fittings.
  • DIN standard eg DIN 18252
  • the electrical shielding of the electrical counterweight relative to the active antenna poles leads to an advantageous propagation of the electromagnetic waves around the lock cylinder, which is characterized in particular by a spherical radiation characteristic, for the transmission and reception properties.
  • the shortening factor which defines the radiation characteristics of a cylindrical antenna relative to a wire antenna, largely compensates for the insufficient overall length with regard to the antenna function.
  • the aforementioned invention forms a powerful antenna system, which offers the advantage, based on a burglar-proof, electronic or mechatronic lock cylinder, to be able to build reliable in-building radio communication, which always works independent of the position of individual doors. This circumstance is of great advantage with increased safety requirements.
  • the function of antenna pole and counterweight can be reversed by a polarization reversal.
  • the directional characteristic of the transmission field changes.
  • the radio communication between the central unit or relay usually runs through the corridors and is mirrored on walls and ceilings, the reception situation inside a room is significantly worse.
  • the outside of a cylinder benefits from so-called parasitic effects while the inside undergoes a more or less strong shielding by walls, doors and furniture.
  • the signal pitch of a remote station can be analyzed in terms of its aspect ratio between the inside and outside of the door to one another.
  • the clear signal distance which thus results between the two Antennenpolarisationen, can now be used to make an authentication of the remote station.
  • a jammer placed in the parking lot in front of a building would create an inverse aspect ratio for the two comparative measurements of the lock cylinder.

  • the knobs (2) are directly formed as active antenna poles, whereas the electric counterweight (5) is formed by the combination of a profile housing with the rotatable cylinder core (3) and the lock bit (4) mounted thereon.
  • an antenna pole forming knob (2) is flanged to the cylinder core (3), wherein between the core (3) and the knob (2) an electrically insulating material (6), thus an insulator is mounted.

  • Fig. 2 is an illustration of the field propagation of common knob cylinders. Shown is first a corridor (7) in which there are four doors, with three of the doors are closed and only one opened. The respective Feidausbreitonne be illustrated as dashed ellipses.
  • the field propagation given in a room (10) is substantially smaller than that in a corridor (7).
  • This is related to the typical installation situation, according to which there is a difference between the signal strength at the outer antenna, ie at the corridor side of an office door, and the inner antenna, as at the room side of an office door.
  • the wireless communication between the central unit, or relay usually runs through the corridors and reflected on walls and ceilings, the reception situation inside a room is significantly worse, since here relatively strong shielding by walls, doors and furniture prevail.
  • individual field propagations of antennas mounted on doors overlap, radio signals and thus information can be transmitted from antenna to antenna be forwarded and transported, for example, to a higher-level property management system. These overlaps are shown hatched in FIG.
  • FIG. 3 shows an illustration of the field propagations achieved with an antenna system according to the invention. Since two superimposed transmission fields are generated by the antenna system described by two active antenna poles, in sum, a spherical radiation pattern. As a result, the field propagation is enormous larger, so that even an opened door (9) does not lead to a break in the transmission of radio signals.
