Abstract

A feedback signal is output as an information signal to a user after entering or automatic reading of identification code and comparing the identification code with stored reference data. The type and intensity of the feedback signal is controlled, based on ambient parameters output by ambient sensors such as microphone (82), photodetector (84) and proximity sensor (86), and stored person-related parameters such as features of disability of user such as mobility-impaired, visually impaired and hearing impaired, and language such as German, English, French and Japanese. An independent claim is included for information signal generation device.

Description

The invention relates to a method for generating an information signal in an access request according to the preamble of claim 1 and an apparatus for performing the method according to the preamble of claim 13.

Access control devices are used by public authorities and commercial companies to protect protected areas or building areas from unauthorized access and to grant access only to authorized persons. In order to grant an authorized person access to the protected area, an identification code entered by the person is evaluated or an identification code carried on a data carrier is read and, if the result of the examination is positive, access is granted by releasing the lock on a door or automatically opening the door.

It is common that the access control device has a signal generator, which reports the evaluation result after evaluation of the access request, such as in the form that access is granted, access is denied or there is a fault, such as a read error when reading an identification data carrier.

Problems in the detection of the feedback signal may result if an optical feedback signal is not recognized due to high ambient brightness or an acoustic feedback signal is not perceived due to high ambient noise. In addition, because of a disability, such as lack of vision or hearing or both disabilities, people may not be able to perceive the usual feedback signals or even find the user communication terminal of the access control device.

The invention has for its object to provide a method for generating an information signal in an access request and a device for performing the method, which is a perception by a user also when impaired by the environment or personal characteristics.

This object is achieved in a method according to the preamble of claim 1 by the features of this claim and solved in an apparatus for performing the method according to the preamble of claim 13 by the features of that claim.

Further developments and advantageous embodiments will become apparent from the dependent claims.

The basic idea of the invention is to adapt information signals individually to the requirements so that, on the one hand, the intended perception is guaranteed by the person requesting the access, but on the other hand the energy input for the transmission of the information signal is kept as low as possible. The latter has its reason once in the economical use of energy, on the other hand, but also in technical terms, as the most transmitted over data cable to the access control device electrical power is limited. By the nature and intensity of the information signal as a function of environmental parameters and personal Parameters is controlled, the power and energy requirements of the access control device is limited to the level just necessary. Furthermore, a general disturbance in the vicinity of user communication terminals of the person holding the access control device is also avoided by the information signals.

Information signals in the context of the invention are feedback signals which are generated after evaluation of an access request, as well as orientation signals that are generated before evaluation of an access request to facilitate a user finding an input device of the user communication terminal for issuing his access request or even allow.

According to one embodiment, feedback signals from the set optical feedback signal, acoustic feedback signal, tactile feedback signal are selected individually or in combination depending on environmental parameters and personal parameters and adjusted in intensity to disturbing parameters with a reliable perception enabling signal to noise ratio with respect to the environmental parameters.

In addition to a targeted selection of the feedback signals for each person concerned, the desire a request for access, the perception of the feedback signal is guaranteed, while only the necessary for the individual feedback case power is used and thus a disturbing influence in the vicinity of the user communication terminal Access control device of restrained persons is avoided.

The type of feedback signals and the intensity of the intensity-controllable feedback signals can be permanently set.

As a result, the type and intensity of the feedback signals can be set to the usual or expected for the installation site of the respective user communication terminal of the access control device but also manually adjust for changes.

Alternatively, the nature of the feedback signals and the intensity of the controllable in intensity feedback signals automatically adjusted and adapted to the environmental parameters.

In this embodiment, a self-adjustment of the type and intensity of the feedback signals takes place without manual intervention.

Furthermore, the feedback signals which can be controlled in intensity can be preset to a basic value and can only be increased in intensity when the signal-to-noise ratio resulting from the ambient parameters exceeds a predetermined limit value.

As a result, as often and as long as possible, the energy and power requirements are kept to a minimum and increased only when necessary.

The intensity of the feedback signals can be controlled by sensors that sense the environmental parameters.

In this way, it is possible not to raise the feedback signals generally when changing the environmental parameters, but individually based on the nature of the changes.

According to a development, the type of feedback signals can be controlled by sensors that detect the environmental parameters.

So it is possible, in extreme brightness and extreme noise, in which neither a visual nor an acoustic feedback could be detected even at the highest signal intensity, a tactile feedback signal, z. B. to select a vibration signal and to generate the user communication terminal. In addition, the visual and audible feedback signal, as meaningless, can be turned off.

Furthermore, the nature of the feedback signals can be controlled by personal parameters stored in a memory of an evaluation and control controller of an access control device or read by the data carrier of a user.

With stored personal parameters, it is possible to enter the data of an access request either by active input or by reading an identification data only on the data volume of the identification data to limit, while the competent for the feedback signals further information does not need to be transmitted, but are already stored in the memory of the evaluation and control controller of the access control device.

For personal parameters read from data carriers, no storage in the memory of the evaluation and control controller of the access control device is necessary. Rather, the personal parameters can be used as control commands for the nature and intensity of the feedback signals.

In the context of the access request, orientation signals can be generated which facilitate a user to find the user communication terminal of the access control device for entering or automatically reading an identification code.

As a result, not specifically disabled in the dark as well as visually impaired and hearing impaired in everyday life, the targeted finding and operating the user communication terminal much easier.

The orientation signals can not be switched on, adjusted, or changed until the approach of a person is detected by a proximity sensor.

This saves energy during the time in which there is no access request and avoids unnecessary disruption to persons in the vicinity of the user communication terminal.

The nature and intensity of the orientation signals may be controlled by environmental sensors that sense the environmental parameters.

As a result, adaptation to the environmental parameters is likewise achieved analogously to the feedback signals.

Furthermore, it can be provided that the access control device is switched from a sleep mode to an operating mode as soon as the approach of a person is detected by a proximity sensor, and is switched back to the sleep mode after evaluating a request for access or after a waiting time.

As a result, an even higher energy saving is achieved, since access control device during the mostly much longer sleep mode compared to the operating mode receives only a small quiescent current.

In a device for carrying out the method, the feedback device in each case comprises at least one signal generator from the set of acoustic, optical, tactile signal generator, the signal generator by software or hardware logic of a terminal controller of a stationary user communication terminal or an evaluation and control controller of a door control device in response to parameters can be selected from the set of stored or read from a user's data personal parameters and environmental parameters and the signal intensity of at least one controllable in intensity signal generator is controlled or adjustable by means of environmental sensors detected environmental parameters.

This ensures that the signal generator of the feedback device can meet at least one perceptible sense of the person requesting access and without active intervention the person requesting access to be selected and adjusted automatically.

The volume of buzzers may include buzzer, beeper, speaker, the amount of optical beacon lamp, light emitting diode, running light, screen and include the set of tactile beacons Braille, braille display, vibrator, infrasonic, air flow generator, infrared flash.

By selecting at least one of these listed signal generator ensures that, depending on environmental influences or personal impairments, it always succeeds to communicate in a suitable manner with the person requesting access, in order to transmit the evaluation result of an access request.

The amount of environmental sensors may include microphone, photosensor, proximity sensor.

In this way, environmental parameters such as ambient noise, ambient brightness and the fact of Capture the approach of a person and use it to control the feedback device.

The stationary user terminal input device may comprise at least one of a set of buttons, a keyboard, a touch screen, a microphone, a passive RFID data carrier, an RFID active data reader, and a mobile user communications terminal communication device. In this case, the communication device can be assigned to the evaluation and control controller of the door control device or the terminal controller of the user communication terminal.

This makes it possible to adapt access requests individually to the abilities of a person requesting access. For example, non-disabled persons could use the push-button, keyboard, touch screen and passive RFID reader as these persons can fully meet the requirements.

In the case of disabled persons, a reader for an active RFID data carrier could be used if the person uses the input device of the stationary user communication terminal can not operate or reach due to a disability. In this case, the transmission of the identification code takes place automatically as soon as the active RFID data carrier has succeeded in the read area of the reading device.

In addition, a mobile user communications terminal carried by a disabled user and having an input device with an input or reading device from the crowd, keyboard, microphone, passive RFID data carrier, and non-contact communication path with the stationary terminal controller may be used User communication terminals or the evaluation and control controller is connectable.

By means of such an input or reading device, the entry of an identification code or the handling of a data carrier with an identification code to be read can be substantially facilitated for a user with reduced mobility.

The mobile user communication terminal may additionally comprise a feedback device with at least one signal generator from the set of acoustic, optical, tactile signal transmitters.

As a result, disabled users can receive feedback signals directly at their location and remote from the stationary user terminal.

As personal parameters, one or more characteristics of a disability may be stored in the memory of the evaluation and control controller from the amount of movement impairment, visual impairment, color blindness, hearing impairment, or be readable as a control feature of the terminal controller from the data carrier of a user.

When stored, it is possible to automatically identify after identification of the person from the memory characteristics of a disability and select the most appropriate for the particular disability type and intensity of the feedback signal.

When reading features of a disability from a data carrier of the user, these features can select as control commands and feedback signals by type and intensity. In this case, feedback signals are also selected according to type and intensity when a person requesting access carries a data carrier which is foreign to the access control device or whose identification code is not is stored in the memory of the evaluation and control controller of the door control unit and therefore not associated with the identification code features of a disability can be evaluated.

Furthermore, as a personal parameter, a language such as German, English, French, Russian, Japanese can be stored in the memory of the evaluation and control controller of the door control unit or readable as a control feature of the terminal controller of the user communication terminal of a user's disk.

In the case of an institution with international employees, the communication language can be automatically selected from the personal parameters, in which notes can be issued and transmitted in voice or text form for the person requesting access.

In addition, the user communications terminal may include an orientation signal generator for facilitating locating the input device.

The orientation signal transmitter can be formed by the feedback device and the signal generator of the feedback device can be switched on, adjustable or changed by the terminal controller of the user communication terminal.

Since feedback signals and orientation signals need not be output at the same time, a double use of the existing signal transmitters as well as a selection according to type and intensity is possible.

The signal transmitters of the feedback device can be controlled by the terminal controller and the environmental sensors on the basis of environmental parameters.

It can thereby be achieved that the orientation signals are only generated when a person requesting access approaches the user communication terminal. Furthermore, the type and intensity of the orientation signals can be adapted to the environmental parameters in the same way as the feedback signals.

Environmental sensors 24 of the stationary user communication terminal 10 include a microphone 82 as an ambient noise sensor, a photosensor 84 as an ambient brightness sensor, and a proximity sensor 86. The terminal controller 26 has software or hardware logic to determine the type and, where appropriate, environmental parameters obtained from the environmental sensors also the intensity of the feedback signals are controlled. For this purpose, tailored to the particular case of need, single or a combination of several signal transmitters of the feedback device 22 is selected and activated.

Additionally or exclusively, by means of the software or hardware logic of the terminal controller 26 from the data carriers 18; 64 read data, which are transmitted in addition to identification codes, evaluated on personal parameters. In the presence of such personal parameters as the nature and degree of disability and / or preferred language, the nature and, where appropriate, the intensity of the feedback signals is also controlled. This is also done by selecting one or a combination of several signal transmitters of the feedback device 22 and to be activated. In this case, a selection of the signal generator can also be carried out with additional logical linkage of the environmental parameters obtained from the environmental sensors.

In the time between presented requests for access the signal generator of the feedback device 22 are turned on as an orientation signal and used to facilitate the access to a person seeking to locate the user communication terminal 10.

1. a) Im Falle einer geringen Umgebungshelligkeit und geringer Umgebungsgeräusche und bei Auswertung der personenbezogenen Parameter dahingehend, dass eine nicht behinderte Person Zugang wünscht, wird zunächst geprüft, ob nach Auswertung der eingegebenen oder gelesenen Identifikationscodes durch Vergleich mit gespeicherten Referenzdaten ein Zugang gewährt oder nicht gewährt werden kann. Bei Gewährung des Zugangs wird dann in üblicher Weise das Schloss einer Tür freigegeben oder die Tür automatisch geöffnet. Bei nicht zulässigem Zugangsbegehren hingegen unterbleibt dies.
   Der zugangsbegehrenden Person wird das Auswerteergebnis über die Rückmeldevorrichtung 22 übermittelt, wobei in diesem Fall lediglich die Ausgabe durch einen Pieper 42 und durch eine Leuchtdiode 40 in der Intensität einer Vor- oder Grundeinstellung signalisiert wird.
2. b) Im Falle eines erhöhten Umgebungslärms oder einer erhöhten Umgebungshelligkeit wird dieser Zustand von entsprechenden Umgebungssensoren 24 erfasst und je nach Art der Umgebungsparameter die Intensität der Lautstärke des Piepers 42 oder die Intensität der Helligkeit der Leuchtdiode 40 erhöht. Ermitteln die Umgebungssensoren 24 eine Umgebungshelligkeit und einen Umgebungslärms, bei denen weder ein akustisches noch ein optisches Rückmeldesignal, auch bei höchster Intensität, die Umgebungsstörungen soweit übertreffen kann, dass sie noch wahrgenommen werden, wird ein taktiler Signalgeber, z. B. der Vibrator 44 selektiert und aktiviert. Dieser versetzt das Gehäuse des Nutzerkommunikationsterminals 10 in Vibration und kann so ein Rückmeldesignal an den Nutzer übermitteln, wenn dieser das Gehäuse mit der Hand berührt.
3. c) Ergibt die Auswertung personenbezogener Parameter eine Behinderung der zugangsbegehrenden Person, wird zusätzlich oder alternativ ein anderer Signalgeber ausgewählt, der nach Art der Behinderung eine zuverlässige Übermittlung des Rückmeldesignals gewährleistet. Ist die behinderte Person sehbehindert, werden optische Signalgeber ausgeschaltet, akustische Signalgeber eingeschaltet oder bleiben eingeschaltet und gegebenenfalls taktile Signalgeber aktiviert. Hierbei kann es sich um eine Blindenschriftanzeige 76, einen Vibrator 44 am Gehäuse des Nutzerkommunikationsterminals 10, einen Infraschallgeber 80, einen Infrarotblitz 48, einen Luftstromgenerator 50 oder einer Kombination einzelner dieser Signalgeber handeln.
4. d) Ist die Zugangsbegehrende Person lediglich farbenblind, kann anstelle der Leuchtdiodenausgabe auch ein Lauflicht 78 aktiviert werden, aus dessen Richtung die Art des Rückmeldesignals (Zugang gewährt, Zugang abgelehnt, Zugangsdaten fehlerhaft oder nicht auswertbar) ablesbar ist.
5. e) Falls eines zugangsbegehrende Person taub ist, werden akustische Signalgeber abgeschaltet und nur einzelne oder mehrere der Signalgeber aktiviert, die eine optische oder taktile Erkennung ermöglichen.
   Bei zugangsbegehrenden Personen, die sowohl in der Sehfähigkeit als auch in der Hörfähigkeit eingeschränkt sind, werden akustische und optische Signalgeber abgeschaltet und nur einer oder mehrere der taktilen Signalgeber aktiviert.
6. f) Bei in der Bewegungsfähigkeit eingeschränkten zugangsbegehrenden Personen, die weder Taster, Tastatur bedienen können noch einen Datenträger dem Lesegerät des Nutzerkommunikationsterminals zuführen oder annähern können, kann vorgesehen sein, dass diese mit einem aktiven RFID-Datenträger 64 über eine größere Entfernung vom Lesegerät 62 ihren Zugangswunsch äußern können. Dabei kann durch die Software- oder Hardwarelogik des Terminalkontrollers 26 ausgewählt werden, ob eine Sprachkommunikation zwischen einer Zentrale hergestellt wird oder Rückmeldesignale über Infraschallgeber 80, Infrarotblitz 48 oder Luftstromgenerator 50 erfolgt.
   Ergänzend oder alternativ können diese Personen aber auch ein mobiles Nutzerkommunikationsterminal 11 mitführen. Dieses nutzt einen berührungslosen Kommunikationsweg zum stationären Nutzerkommunikationsterminal 10. Über einen Taster des Eingabegeräts 32 kann z. B. ein Lesegerät 62 für einen aktiven RFID-Datenträger 64 eingeschaltet und der mitgeführte aktive RFID-Datenträger 64 zum Senden veranlasst werden. Über eine Tastatur des Eingabegeräts 32 und/oder ein Lesegerät 30 für passive RFID-Datenträger 18 können Identifikationscodes analog zur Eingabe oder zum Lesen mittels des stationären Nutzerkommunikationsterminals von der Ferne aus berührungslos übertragen werden.
7. g) Im Falle, dass Rückmeldungen in ausführlicher Form im Klartext über einen Bildschirm 46 oder einen Lautsprecher 42 ausgegeben werden, kann darüber hinaus mittels gespeicherter personenbezogener Parameter und der Logik des Terminalkontrollers 26 des Nutzerkommunikationsterminals 10 die Sprache ausgewählt werden, in der mit der zugangsbegehrenden Person optimal kommuniziert werden kann.
8. h) Über einen Orientierungssignalgeber, der auch durch die Rückmeldevorrichtung 34 gebildet werden kann, werden bei Annäherung einer zugangsbegehrenden Person Orientierungssignale generiert, die ein Auffinden des Nutzerkommunikationsterminal 10 erleichtern. Bei erteiltem Zugang kann auch ein Signal generiert werden, das ein Auffinden der Zugangstür erleichtert.
9. i) Bei Änderungen der Umgebungsparameter werden diese durch die Umgebungssensoren 24 erfasst und die Orientierungssignale so angepasst, dass sie auch bei erhöhter Umgebungshelligkeit und Lärm wahrgenommen werden können.

The mode of operation is described below using a few scenarios.

1. a) In the case of a low ambient brightness and low ambient noise and the evaluation of the personal parameters in such a way that a non-disabled person wishes access, it will first be checked whether access is granted or not granted after evaluation of the entered or read identification codes by comparison with stored reference data can. Upon granting access then the lock of a door is released in the usual way or the door is opened automatically. Inadmissible access request, however, this is omitted.
   The person requesting accession receives the evaluation result via the feedback device 22, in which case only the output is signaled by a beeper 42 and by a light-emitting diode 40 in the intensity of a pre-setting or basic setting.
2. b) In the case of increased ambient noise or increased ambient brightness, this state is detected by corresponding environmental sensors 24 and, depending on the type of environmental parameters, the intensity of the volume of the beeper 42 or the intensity of the brightness of the light-emitting diode 40 is increased. Determine the environmental sensors 24 an ambient brightness and ambient noise, in which neither an acoustic nor an optical feedback signal, even at the highest intensity, the environmental disturbances can far exceed that they are still perceived, is a tactile signal generator, eg. B. the vibrator 44 is selected and activated. This vibrates the housing of the user communication terminal 10 and can thus transmit a feedback signal to the user when the latter touches the housing by hand.
3. c) If the evaluation of personal parameters results in a disability of the person requesting the access, another signal generator is additionally or alternatively selected which ensures a reliable transmission of the acknowledgment signal according to the type of disability. If the person with disabilities is visually impaired, optical signal transmitters are switched off, acoustic signal transmitters are switched on or remain switched on and if necessary, tactile signal transmitters are activated. This may be a braille display 76, a vibrator 44 on the housing of the user communications terminal 10, an infrasonic trigger 80, an infrared flash 48, an airflow generator 50, or a combination of individual ones of these transducers.
4. d) If the person requesting admission is only colorblind, a running light 78 can be activated instead of the light emitting diode output, from the direction of which the type of acknowledgment signal (access granted, access denied, access data incorrect or not evaluable) can be read.
5. e) If a person requesting access is deaf, the acoustic signalers are switched off and only one or more of the signal transmitters are activated, which enable visual or tactile detection.
   In persons requiring access, who are impaired in their ability to see and hear, audible and visual signaling devices are switched off and only one or more of the tactile signaling devices are activated.
6. f) may be provided that with an active RFID data carrier 64 over a greater distance from the reader 62 their. In motion impaired persons requiring accessibility who can operate neither buttons, keyboard nor a disk to the reader of the user communication terminal or approach access request can express. It can be selected by the software or hardware logic of the terminal controller 26, whether a voice communication between a control center is made or feedback signals infrasonic sounder 80, infrared flash 48 or air flow generator 50 takes place.
   In addition or alternatively, however, these persons can also carry a mobile user communication terminal 11. This uses a non-contact communication path to the stationary user communication terminal 10 via a button of the input device 32 can, for. B. a reader 62 is turned on for an active RFID disk 64 and the entrained active RFID disk 64 are caused to send. Via a keyboard of the input device 32 and / or a reading device 30 for passive RFID data carriers 18, identification codes analogously to input or reading by means of the stationary user communication terminal can be transmitted without contact from a distance.
7. g) In the event that feedback in detailed form in plain text via a screen 46 or a speaker 42 are output, can also use stored personal parameters and the logic of the terminal controller 26 of the user communication terminal 10 are selected the language in which can be optimally communicated with the accessing person.
8. h) Via an orientation signal transmitter, which can also be formed by the feedback device 34, orientation signals are generated when approaching a person requesting access, which facilitate finding the user communication terminal 10. With granted access, a signal can also be generated which facilitates finding the access door.
9. i) With changes in the environmental parameters, these are detected by the environmental sensors 24 and the orientation signals are adjusted so that they can be perceived even with increased ambient brightness and noise.
