Definitions

• the invention relates to a passage control device for contactlessly operating data carriers, with an antenna unit which has a front wall which extends in the passage direction and faces the passage and has a height corresponding to the different carrying height of the data carriers, on which at least one antenna for data transmission in the radio wave range is arranged is, and with a turnstile with an inclined downward axis of rotation and locking arms inclined to the axis of rotation.
• Such a passage control device is known (DE 9490094 UI).
• the person to be checked carries e.g. in the form of a wristwatch or in the form of a card in a pocket of clothing as a data carrier, a transponder that works with a transmitter and receiver unit for transmitting energy and data via the antenna in the radio wave range.
• the data transmission is limited to the area immediately in front of the antenna.
• the passing time of the person to be checked on the antenna must therefore correspond to the transaction time required for data transmission, which results in a relatively large length of the antenna unit of, for example, 30 cm to 80 cm.
• the antenna must also have a not inconsiderable height of, for example, 40 cm to 100 cm in order to accommodate the different sizes of the trolling people (child - larger than average adult) and the attachment of the data carrier at different heights of the person (pocket - pocket on the upper arm).
• at least part of the electronics of the transmitting and receiving device is accommodated in the antenna unit, so that it also has a certain depth.
• the antenna unit thus forms a massive, optically unappealing box. If several passageways with such antenna units are arranged next to one another, this increases the stiffness considerably.
• the antenna unit has been provided with a curvature with an axis of curvature extending in the direction of passage.
• the concave shape of the large front wall thus created suggests a technicity that reduces the visual impression of the bulkiness, but not to a satisfactory extent.
• the curved shape of the antenna unit is associated with a not inconsiderable additional manufacturing effort.
• the object of the invention is to provide a non-contact passage control device with an optically compatible antenna unit at low production costs.
• This is achieved according to the invention in that the front wall of the antenna unit, together with at least one antenna, extends downward beyond the bearing of the turnstile, the turnstile is mounted on the front area of the antenna unit in the passage direction, and the section extending downward beyond the turnstile bearing the front wall extends obliquely to the rear.
• the lower portion of the front wall of the antenna unit is inclined rearward.
• the front wall of the antenna unit which extends in the direction of passage and faces the passage, is designed at least in the upper region as an information surface for optical information.
• the front wall thus has an additional function that eliminates the visual impression of the mass of the antenna unit. The perception of the information leaves other impressions in the background for the viewer.
• the optical information with which the front wall of the antenna unit is provided can be designed in different ways. It can be alphanumeric and / or visual information, possibly also moving images.
• the front an ⁇ can, for example, be provided with a map of the respective area or be designed as an advertising space. It is also possible, for example on a ski lift, to design the front wall as a mirror for the winter landscape.
• the front wall can be provided with permanent information, for example a map, or with changeable information.
• the front wall can have, for example, clamps or magnetic holders for posters or spaced guides with grooves into which an information board is inserted with its edges.
• the front wall can also be designed such that it can be illuminated, if appropriate also by means of interior lighting.
• the front wall of the antenna unit can be provided with a recess in which a poster, a blackboard or the like.
• Flat information material can be fastened.
• its rear wall can also be designed as an information area.
• the antenna unit according to the invention is excellently suitable for attachment for several antennas.
• contactless data carriers are used, in which different carrier frequencies are used for data transmission in the radio area (10 4 - 3.10 9 Hz).
• carrier frequencies for data transmission in the radio area (10 4 - 3.10 9 Hz).
• data carriers that work at 13.56 MHz, a carrier frequency provided according to an ISO standard and others with another, e.g. B. manufacturer-specific carrier frequency.
• Data carriers are also known in which a frequency change takes place, for example after card identification for more secure and faster data transmission (“frequency hopping”) (cf. EP-A-0642096).
• Fig. 1 is a perspective view
• 2 and 3 are a front and side view of the passage control device.
• a passage control device 3 is arranged in a passage 2 on a frame 2 with adjustable height.
• the passage control device 3 has a turnstile 4, an antenna unit 5 and a further attachment unit 6, which has a device for reading passive data carriers to be inserted in a slot 7.
• the turnstile 4 is attached to the frame 1 as an attachment unit, the antenna unit 5 as an attachment unit to the turnstile 4 and the attachment unit 6 to the antenna unit 5.
• the turnstile 4 has an axis of rotation 8 directed obliquely downwards to the passage 1 at an angle of approximately 45 °, which is mounted in a housing 9 and carries a plurality of locking arms 10 arranged at an angle of approximately 45 ° to the axis of rotation 8.
• the housing 9 contains a drive motor.
• an optoelectrical sensor for actuating the turnstile drive not shown, is provided, which at the same time can control a single-colored or multi-colored traffic light 20, which indicates to the operating personnel whether the turnstile 4 has been actuated by the respective data carrier or not.
• the antenna unit 5 consists of a large front wall 12 facing the passage 1, a rear wall 13 ′′ parallel to it and narrow side walls 22, 23.
• the outer antenna 13 can, for example, be designed for a carrier frequency of 125 kHz, the inner antenna 14 for a carrier frequency of 13, 56 MHz.
• the antennas 13, 14 absorb the energy of the contactlessly working, active data carriers designed as transponders and the information exchange between these data carriers, which the persons to be checked carry somewhere on the body, for example on clothing, and the transmitting and receiving device (not shown) Data control device 3.
• the range of the antennas 13, 14 is limited to a few decimeters, so that the transaction between the contactless data carrier and the transmitting and receiving device is limited to the time that the person to be checked needs to pass through the antennas 13, 14.
• the transaction time necessary for the cooperation between the contactless data carrier and the transmitting and receiving device thus determines the length of the antenna unit 5.
• the height of the antenna unit 5 is determined by the different height at which the data carriers are carried by the people passing through the passage 1 (e.g. child - adult; e.g. pocket - upper arm).
• the antenna unit thus also has a corresponding height, for example 70 cm, with a length of, for example, 50 cm.
• the housing 9, in which the turnstile 4 is mounted is arranged on the front edge of the antenna unit 5 in the direction of passage (arrow 15 in FIG. 2), specifically in a recess 16 in the lower region of the antenna unit 5, which is otherwise on the right ensures reliable individual isolation, that is, prevents a person from standing in front of the antenna unit 5 and the turnstile 4 between a person with a contactless data carrier who, when the turnstile 4 is actuated, passes through the turnstile 4 by the person carrying the contactless data carrier without authorization.
• the antennas 13, 14 and thus the antenna unit 5 extend downward beyond the housing 9 or the turnstile bearing.
• the section 17 of the antenna unit 5 is inclined obliquely backwards away from the passage 1 below the area of the turnstile housing 9.
• the section 18 can have guides 19, for example, into which an information board (not shown) can be pushed, on which e.g. an adhesive film can be glued inside and outside.
• an information board not shown
• an adhesive film can be glued inside and outside.
• the information can also cover the entire front wall 12, that is to say also the lower section 17.
• the upper section of the antenna unit 5 and thus the information surface 18 are inclined slightly backwards away from the passage 1, for example with an inclination angle ⁇ of 5-20 °, in order to provide an optimal viewing angle for the Pass 1 passing person on the Infor ations läcne 18 to receive.
• the insertion of a contact-bearing or magnetically working data carrier into the slot 7 of the add-on unit 6 is facilitated, since the inclined information surface 18 prevents the person from coming into contact with their shoulder with the information surface 18 when inserting it.
• the front wall 12, including the lower section 17, can also have a convex shape that is curved toward the passage 1, that is to say without an edge between the upper section of the antenna unit 5 and the lower section 17.
• the front wall 12 of the antenna unit 5, together with at least one antenna 13, 14, extends downward beyond the bearing or the axis of rotation of the turnstile 4.
• the bearing 8 of the turnstile 4 is mounted in the front region of the antenna unit 5 in the passage direction 15, the section 17 of the front wall 12 extending downward beyond the turnstile bearing 8 extending obliquely to the rear.
• This forms a large antenna surface or front wall 12 which, due to its large length in front of the turnstile in the direction of passage 15, means that the person to be checked has a correspondingly long passage time from entry into the range of the at least one antenna 13, 14 to the turnstile 4 and thus a corresponding one ensures long transaction times for data transmission, while their large height ensures that the data carriers can be carried by people passing through the passage at quite different heights.
• the lower section 17 of the front wall 12 of the antenna unit 5 is inclined backwards away from the passage 1. Through the large front wall 12 thus formed
• the antenna unit 5 also has a large area which can be used excellently as an information area 18.
