Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The invention will be explained in mo so detail below by means of the enclosed figures.

[0029] FIG. 1 shows a schematic illustration of an access control device of an access control system for vehicles for illustrating the method according to the invention; and

[0030] FIG. 2 shows a schematic illustration of an access control system for persons comprising a multi-lane access, wherein an access control device is assigned to every access lane, for illustrating the method according to the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] FIG. 1 illustrates an access control device for vehicles, comprising a parking column 1 and a barrier beam 2, wherein a vehicle is identified with 3. According to the invention, the verification of the access authorization for the vehicle 3 is carried out by means of the evaluation of an ID, which is transmitted at regular intervals by a mobile electronic device 4 located closest to an access control device of the access control system in access direction, by means of a first standard in the context of a “broadcasting”, to which ID at least one access authorization, which is received by means of transmitting-receiving units connected to a computer 8 comprising a CPU and storage means, within the range of the mobile electronic device 4, is assigned in an unambiguous manner.

[0032] In the shown example, a mobile electronic device 4 is identified as the mobile electronic device 4 located closest to the access control device in access direction, when the mobile electronic device 4 receives a short-range signal 7, which is emitted by the access control device or which is caused by the access control device, and has a range, which covers an area around the access control device, in which only one vehicle can be located. In the case of the shown example, the parking column is made of metal or comprises metal parts, so that the magnetic field 7 around the access control device is influenced, which is detected by a magnetic field sensor of the mobile electronic device 4, when it is located in the area around an access control device, in which the influencing of the magnetic field can be detected by means of the access control device. Due to the dimensions, only one vehicle can be located in this area.

[0033] When the mobile electronic device 4, which is located in the vehicle 3 behind the windshield in the shown example, detects the influencing of the magnetic field 7 by the parking column 1, the information that the mobile electronic device 4 receives the short-range signal, namely the influencing of the magnetic field, which is caused by the access control device, is also transmitted to the computer 8 in the context of the “broadcasting” by means of the first standard. In the context of the “broadcasting”, the ID transmitted by the mobile electronic device 4 at regular intervals is evaluated in the context of the “broadcasting”, wherein, when a valid access authorization is assigned to this ID, the access control device, which is connected to the computer 8 via a data link, is controlled in such a way that the barrier beam 2 is operated to open.

[0034] With reference to FIG. 1, the access control device has a magnetic field sensor 5, which is attached to the parking column 1 and by means of which a vehicle 3 located in the entry or exit, respectively, is detected, in addition or as an alternative to an induction loop, which is used according to the prior art to detect a vehicle located at a parking column 1 in the entry or exit, respectively, and to activate the corresponding access control device.

[0035] An access control system for persons comprising a multi-lane access is the subject matter of FIG. 2, wherein two access lanes 9, 10 are shown and an access control device 11, 12 is assigned to each access lane 9, 10. Two electronic components, comprising at least one electromagnet, are hereby assigned to each access control device 11, 12, by means of which electromagnet the magnetic field can be influenced in a specific way in a defined area around the access control device in such a manner that this can be detected by a mobile electronic device 4, 4′, which is located in this area, wherein the area is chosen in such a way that only one person can be located in this area. In the case of the example according to FIGS. 2, 13 and 14 identify the electronic components, which are assigned to the access control device 11, wherein 15 identifies an electronic component, which is assigned to the access control device 12; 16 furthermore identifies a further electronic component, which is assigned to a non-illustrated, further access control device. The electronic components 13, 14, 15, 16 are also embodied and/or arranged and/or shielded in such a way that the influencing of the magnetic field can be detected in a defined angular range around the respective access control device, whereby the influencing of the magnetic field can be detected only by mobile electronic devices 4, 4′, which approach the respective access control device in access direction and along the access lane. The electromagnets of the electronic components are furthermore controlled in such a way that the magnetic field generated by the electronic components, which are assigned to an access control device, has an unambiguous characteristic assigned to the access control device, which differs from the characteristic of the magnetic fields generated by the electronic components, which are assigned to the further access control devices, in order to identify the respective access control device via the characteristic of the magnetic field in this way. For example, the magnetic fields 19 generated by the electronic components 13, 14 can be amplitude-modulated in such a way that they differ unambiguously from the magnetic field 18 generated by the electronic component 15 with regard to the amplitude modulation.

[0036] According to the invention, a mobile electronic device 4 is identified as the mobile electronic device, which is located closest to the access control device 11 in access direction, when the mobile electronic device 4 receives a short-range signal 19, which, in the shown example, corresponds to the magnetic field generated by means of the electronic components 13, 14, which are assigned to the access control device 11. In the case of the shown example, two electronic components are assigned to each access control device; in the alternative, one electronic component can be assigned to each access control device.

[0037] In the case of the shown example, the mobile electronic device 4, which is embodied as smart phone, detects the magnetic field of both electronic components 13, 14, which are assigned to the access control device 11, so that, according to the invention, it is detected as the mobile electronic device, which is located closest to the access control device 11, wherein the characteristic, e.g. the amplitude response or amplitude ratios of the magnetic field are also transmitted within a defined time interval after the detection of the magnetic field in the context of the “broadcasting” via the first standard, wherein the access control device 11, to which the mobile electronic device 4 is located closest, is identified in the computer 20 by means of the characteristics. Reference numerals 21, 22 in FIG. 2 identify the magnetic fields, which are influenced by the access control devices 12, 11 and which are also detected by means of a magnetic field sensor of the mobile electronic devices, when they are located in an area around an access control device 12, 11, in which the influencing of the magnetic field by the metal parts of the access control device 12, 11 can be detected. In the shown example, however, the magnetic fields generated by means of the electronic components, which are assigned to the respective access control device, are used to determine the mobile electronic device located closest to an access control device 11, 12. In the case of a one-lane access comprising an access control device, which has metal parts, the electronic components can be forgone, because a differentiation between two or more access control devices can be forgone.
