The present invention further relates to a door with such a door drive and a method for detecting an object and / or living being in a door opening area.

Description

The invention relates to a door drive according to claim 1, claim 13 and claim 14.

From the DE 198 31 806 C2 is a door operator for opening or closing a door, with a control device and a housing which is attached to the door frame known.

Further, anti-theft systems that are located in the area of a door are out of the DE 10 2006 029 827 B4 already known. In this case, so-called RF labels are attached as merchandise security labels on goods. These include a coil and a capacitor which form a resonant circuit with a label typical resonant frequency.

In an external radio frequency electromagnetic field tuned to the resonant frequency of the RF tags - typically around 8.2 MHz - the resonant circuit deprives the system of transmission energy and is thus detectable. If an undeclared RF tag is detected, an alarm is triggered.

However, in order to provide a radio frequency field, transmitter units and the opposite receiver units that detect the reduced transmitter power must be provided. That is, a passage through a door, at least on the vertical sides, must have opposing transmitter and receiver units, respectively, to allow for a radio frequency field.

In some cases, horizontally arranged transmitter / receiver units are provided in addition to the vertically arranged transmitter / receiver units. The use of transmitter / receiver units requires a relatively large amount of space, and arranged in the ground transmitter / receiver units must be installed consuming in the ground.

The object of the present invention is to provide anti-theft systems which are arranged in the region of a door, which, on the one hand, take up less space and, on the other hand, can identify objects or persons marked in the region of a door opening.

This object is solved by the subject matter of claim 1. Further advantageous embodiments of the invention are the dependent claims, the following description and the drawings removed.

The object is thus achieved by a door drive for opening and / or closing a door with a control and a housing which is attachable in or on a door frame of the door, wherein the door drive at least one receiver of a transceiver system for automatic and non-contact Identifying and / or locating objects and / or animals in a surveillance area of the transceiver system, wherein the at least one receiver is provided in or on the housing of the door operator, wherein transmitters of the transceiver system are on or in the objects and / or living beings are arranged, and wherein the monitoring area corresponds to at least a part of an opening area of the door, preferably the entire opening area of the door.

Transmitter-receiver systems, for example, by means of radio waves enable automatic and non-contact identification and / or localization of receivers, do not require pairs of opposite transmitter and receiver units, whereby the space requirement of the door drive can be minimized. Accordingly, such readers can be arranged on only one side of a door opening. In automatic door systems, the door drive is usually arranged above a passage of the door. Thus, the readers or sensors are arranged only above the passage and do not require a horizontal arrangement in which in addition a receiver or transmitter must be installed in the ground.

Even with an arrangement of the readers in or on the drive housing, these are not visible to the outside, which is very important for aesthetic reasons, especially in department stores.

In addition to the function for securing merchandise, the readers in the door area can recognize persons through corresponding chips and authorize or block them for access or passage. Furthermore, the data recorded by the readers can be evaluated in a data center and mapped as needed. Here, e.g. By means of the acquired data, it is analyzed whether the number of sold objects also corresponds to the number of objects that pass through a door.

Preferably, the transceiver system is an RFID system, wherein the transmitter is an RFID transponder and the receiver is a reader, wherein the reader is configured to power the RFID transponder to provide an identifier included in the RFID Transponder is stored, to query. The invention thus describes a system which operates on the basis of an integrated RFID (Radio Frequency Identification) technology. By means of a reading device or a reading device, passive RFID transponders, which are applied to a commodity or to a person can be detected. The detection of the RFID transponder is preferably displayed. For example, UHF (Ultra High Frequency), LF (Low Frequency) and HF (High Frequency) technologies can be used. The technology used depends on the height and width of the area to be secured. When applying the respective technology, the ISO / IEC 18000 can be taken into account.

The use of passive and / or active RFID chips as receivers allows the monitoring of very wide passages, for example. From three to seven meters wide. In particular, when the invention is designed to detect persons, sensor fields, which are usually controlled by chips with a short range (<5 cm) and serve for access control, become superfluous.

The passive RFID transponders can be managed with dedicated software. The passive RFID transponder may be formed in a solid form or as a stick-on label. The detection field of the integrated RFID wide-range reader or the wide-range reading device can display the exit region of the goods (objects) in the corresponding detection field by signal transmitters by means of a adjusted and defined width.

The passive RFID transponder can be deactivated and / or activated at a suitable device or, alternatively, provided with a new identifier, so that a legitimate passage of an object or a person through the door can be determined by means of the device. After the deactivation of an RFID transponder, for example, on the goods by a suitable device, the RFID transponder is either recognized by the evaluation unit, but not reported as unauthorized, or not recognized.

Alternatively, the RFID transponder, which was originally attached to a product, be removed by means of a suitable device, so that this product can not be recognized by the at least one reader.

Preferably, the door drive is arranged above the door opening area in order to further reduce the space requirement. Furthermore, the receivers can be provided by this measure in a simple manner in the door area.

More preferably, at least a part of the housing of the door drive is arranged on a cross bar of the door frame or is integrated in this. Here, the door drive not only in a ceiling area can not be arranged visible, and the monitoring range of the reader can extend over the entire height of a door. In particular, at least a part of the housing may form part of the transverse bar of the door frame. By this measure, the space requirement of the door drive according to the invention can also be further reduced

Preferably, at least two, preferably two to six, receivers are provided, wherein the at least two receivers are distributed over the width of the door opening area, in particular evenly distributed. Thus, the width of a surveillance area can be arbitrarily adapted and expanded to the width of a door, so that a recognition of receivers in the door area is also possible over the entire width of a door.

According to an advantageous embodiment, the at least one receiver is connected to a control of the door drive. By connecting to the controller, doors and receivers stored in a database interact with each other, so that, for example, the door can be locked in the event of unauthorized access, or a silent or loud alarm can be triggered.

According to a further advantageous embodiment, the at least one receiver, preferably all receivers of the transceiver system, is connected to a data evaluation system, wherein the data evaluation system is preferably connected to the control of the door drive. By means of a data evaluation system connected to the sensors, goods data, personal data, etc. can be evaluated. For example, RFID chips are already used today for securing merchandise in many shops, with an inventive door drive without major conversion can be integrated into existing systems without major problems.

The data evaluation system is preferably provided on a PC, a tablet, a smartphone or the like. On the one hand, such systems make it possible to quickly acquire the data exchanged in the transceiver system and, on the other hand, the data can also be transmitted simultaneously to several persons for checking.

Preferably, the data evaluation system is designed to recognize transmitters, preferably all transmitters which are present in the door opening area, by means of the at least one receiver. Thus, several transmitters that are in the area of the door can be detected at the same or similar time. This is especially true of a large door where many people enter or leave a building or shop at the same time and / or several products that can be present in a shopping cart, can be pushed through a door simultaneously, important.

In particular, at least one device for emitting an electrical, optical and / or acoustic signal is provided, preferably in or on the housing of the door drive. By means of such a device, authorized and unauthorized passages, for example of persons and / or objects, can be displayed.

Preferably, upon detection of a predefined transmitter by means of the Datenauswertesystems, the door drive is adapted to control the at least one device for emitting an electrical, optical and / or acoustic signal such that an electrical, optical and / or acoustic signal is emitted. Thus, e.g. the unauthorized removal of objects is displayed directly at the door.

Also, the door drive can be controlled upon detection of a predefined transmitter such that the door is opened or closed. In this context, at least one further sensor, preferably a proximity sensor, for example, based on infrared or radar, arranged in the region of the door frame and connected to the controller. Upon detection of a predefined transmitter by means of the data evaluation system, a function initiated by receiving the signals of the further sensor is suppressed by the controller.

This means, for example, that when the proximity sensor actually wants to open a door to allow, for example, the passage of a person, upon detection of a predefined transmitter on an object in the person's hand or on the person kept the door closed by the controller because the object or the person may not pass the door.

Preferably, the transceiver system is adapted to emit and receive radio waves preferably in the UHF range of 350 to 950 MHz, in particular 850 to 950 MHz. UHF wide-range readers have an adjustable detection range of several meters and are therefore also suitable for door widths and heights of several meters, for example of five meters.

Preferably, all receivers of the transceiver system are arranged at at least substantially the same height, and preferably above a floor. In this way, no receivers or readers of the transceiver system in the floor or on a side wall in the region of the door or the door frame are necessary.

According to a further aspect, the invention relates to a door comprising a door drive according to the invention. The door according to the invention can be used both building and mobile.

According to a further aspect, the invention relates to a method for recognizing an object and / or living being in a door opening area, wherein a transmitter of a transceiver system for automatically and contactlessly identifying and / or locating objects and / or living beings on or in the object or Living thing is arranged and at least one receiver of the transceiver system on the door drive of the door arranged or integrated, wherein upon detection of a predefined identifier of a transmitter in the door opening area, a signal is output, indicating whether the object or living beings the door rightfully may cross.

Preferably, the signal comprises an electrical, visual and / or audible warning signal, and preferably the warning signal is used to trigger a security action.

Preferably, at least one further sensor, in particular a proximity sensor, is provided, and the receiver signals of the transmitter-receiver system are linked to the sensor signals of the further sensor. In particular, a function initiated upon receiving a signal of the further sensor is suppressed in the presence of a signal of the transceiver system.

Each reader generates this 22 a separate detection field 28 ' , It should be noted that objects 24 or living beings 26 can be identified by multiple readers and / or localized when the individual detection fields 28 ' overlap.

The area of the surveillance area 28 in the plane of the door frame 14 corresponds to the height H times the width B , The three objects 24 in the 1 are shown are arranged at different heights and can all by means of at least one of the readers 22 be identified.

This means that through the use of readers 22 in a predefined monitoring area 28 the entire surveillance area 28 on the presence of objects 24 and / or living things 26 can be checked. For this purpose, on or in the objects 24 or living things 26 so-called transmitter or transponder 32 arranged. All readers 22 the transceiver system 1 are arranged on at least substantially the same height. This height is parallel to a floor and in the drawing corresponds approximately to the middle of the cross bar 20 ,

The number of readers used 22 depends on how wide the door frame 14 the door 10 and, secondly, the technology used. When using multiple readers 22 , for example, from two to six readers 22 , these are even across the width B of the crossbar 20 of the door frame 14 arranged. The readers 22 be on a case 36 of the door drive 12 in the area of the cross bar 20 intended.

Preferably, at least part of the housing forms 36 of the door drive 12 at least part of the cross bar 20 , There is also the possibility that the housing 36 of the door drive 12 also the entire crossbar 20 of the door frame 14 forms.

The 4 further shows a device 40 for emitting an electrical, visual and acoustic signal. The device 40 is in the area of the posts 16 . 18 of the door frame 14 arranged. Such a device 40 can also be used in the embodiments of 1 to 3 be provided and could also be provided in addition or only on the crossbar.

RFID elements (Radio Frequency Identification Elements) are used in transceiver systems 1 for the automatic and contactless identification and / or localization of objects 24 or living beings 26 with radio waves 30 used. An RFID system typically includes a transponder 32 Also referred to as "tag" or "tag", which includes an antenna (not shown) and located on or in the object 24 or living beings 26 located.

A transponder 32 typically includes a distinctive code (identifier) that is transmitted through the antenna from a reader 22 of the RFID system 1 , also called "transceiver", can be queried. The transceiver 22 also includes an antenna (not shown) and a transceiver circuit (also not shown) for reading this identifier from the transponder 32 ,

For reading the identifier from the transponder 32 The reader typically generates alternating magnetic fields to signals by means of the radio waves 30 to the transponder 32 transferred to.

The transponder 32 is adapted to receive a corresponding signal from the reader 22 a data, in particular the identifier, comprehensive signal 30 ' in response to the reader 22 to send this back to a data evaluation system 34 , For example, a computer system, forward for further use or can evaluate by means of a microcontroller itself. The term of returning is also used here when the transponder 32 is designed, the magnetic field of the reader 22 to influence without generating a magnetic field. This influence is then by the reader 22 detected.

So-called passive and / or active RFID chips can be used. RFID chips can be considered as possible transponders 32 in the UHF, LF and / or HF range and allow the monitoring of very wide doorways.

RFID chips, which are operated for example in the UHF range, usually use signals in the frequency range from 430 MHz to 950 MHz, in particular in the range of 850 MHz to 950 MHz. When using these frequencies, passive transponders 32 (ISO / IEC 18000 ) with a range of 2m to 6m and active transponders 32 with a range of up to 100m be identified. The data in the transponder 32 can be stored in plain text, ie unencrypted, or encrypted to the reader 22 be transmitted.

In order to communicate the signals of the readers as error-free as possible 22 To guarantee these are with the control 38 of the door drive 12 connected. Furthermore, all readers are 22 of the transmitter-receiver system 1 additionally with a data evaluation system 34 connected. The data evaluation system 34 is designed to be transmitter 32 , preferably all transmitters 32 , which are present in a door opening area to recognize.

In use of the transceiver system 1, the readers become 22 trained to radio waves 30 send out and thus the RFID transponder 32 in the area of the door 10 are available to provide energy. Here, the transponder 32 signals 30 ' send out by the readers 22 to be read. The signals 30 ' include an identifier included in the respective RFID transponder 32 is deposited. The identifier may indicate if an RFID transponder 32 authorized or unauthorized is the door 10 to cross. This also means that on objects 24 or to living things 26 existing transponders 32 no own energy source needed.

The door drive 12 is designed to detect a predefined transponder 32 by means of the data evaluation system 34 the at least one device 40 to send out an electrical, optical and / or acoustic signal in such a way that an electrical, optical and / or acoustic signal is emitted, for example, in order to trigger a safety action.

For example, by means of the controller 38 the door drive 12 upon detection of a predefined RFID transponder 32 by means of the data evaluation system 34 be notified that a person is passing through one of the readers 22 monitored door should be denied, with the triggered security action closing the door 10 includes.

This means that the backup action allows the door to be activated 10 such that it is closed. Should a person be granted passage, the door drive can 12 alternatively be controlled so that the door is opened. Another example of a backup action may be the triggering of a silent or loud alarm by the device 40 be.

The backup action may accordingly be a function of the controller 38 during normal operation of the sliding door 10 bridged. For example, the data evaluation system 34 cause signals of a proximity sensor, which should automatically open the sliding door when a person is detected, to be suppressed. This can happen, for example, as soon as persons or objects marked are in the door opening area, which should be prevented from passing through the door, so that the sliding door 10 remains locked, although the proximity sensor indicates the presence of a person.

Preferably, the door drive 12 used to detect if the object 24 or living things 26 the door may legally cross.

As an alternative, the door drive could 12 also be formed, for example, when used in department stores to be marked persons 26 to recognize, after registration of the marked person 26 by means of the data evaluation system 34 notify the department store staff that the designated person 26 enters the department store. This could then be the designated person 26 Automatically a Personal Shopper or another type of Advisor specific to the designated person 26 to provide.
