Abstract
Description
Technology Field
[0001] The present invention relates to a voice recognition-based intelligent access authorization kiosk, and more specifically, to a voice recognition-based intelligent access authorization kiosk device that automatically identifies visitors based on artificial intelligence (AI), switches to voice mode when a visually impaired person or wheelchair user is present, and processes visit processing and access authorization through voice guidance, thereby promoting management efficiency and improving user convenience and accessibility. Background Technology
[0002] Recently, lax access control has made unauthorized entry easy, resulting in frequent incidents of kidnapping and sexual assault on campus. Furthermore, while the number of places utilizing kiosks to process visits, reservations, and entry authorizations has increased in recent years, relying solely on these existing kiosk devices has limitations in optimally managing school access control.
[0003] Meanwhile, when visiting the school, a daily visitor pass log must be completed and a pass issued after identity verification; visitors may then enter the school wearing the pass. In this case, an administrator is absolutely necessary to manage access.
[0004] Recently, with the advancement of IT technology, it has become possible to visit the school by making a reservation in advance through an electronic guestbook.
[0005] For example, as illustrated in FIG. 1, a school visitor uses a terminal to input information requested for a school visit on a school visit website and requests pre-visitor registration. Subsequently, once the information is entered and phone number verification is completed, the visitor is approved as a reservation holder, and the reservation information is transmitted to the user terminal. When a pre-registered visitor presents the entry information upon visiting the school, it is read by a kiosk or similar device; if the visitor is a valid visitor with permission to enter, a daily visitor pass is printed. The visitor can then enter the school by wearing the printed daily visitor pass.
[0006] If you visit a school without registering in advance, you can visit the school by registering as a visitor through an on-site registration procedure as shown in Fig. 2.
[0007] For example, visitors enter their information at the electronic entry kiosk installed at the school entrance and authenticate themselves through methods such as phone number verification. Once authentication is successfully completed, a daily visitor pass is printed. Visitors simply need to wear the printed pass to enter or exit the school.
[0008] However, as mentioned above, the kiosk device that processes entry authorization when visiting a school is a device used for general users, and since input devices such as keypads for screen operation or information input, or screen positions, are installed in locations intended for general users, disabled people or wheelchair users experience significant inconvenience in using it.
[0009] In particular, for the visually impaired, it is difficult to see the screen, and even with a separate Braille input device, there is a disadvantage in that it is inconvenient to operate; similarly, wheelchair users or short users also find it difficult to see the screen or operate the input keys.
[0010] Therefore, there is a need for technology that simplifies the access authorization process through visit reservations when visiting schools, while simultaneously enhancing security and enabling visually impaired individuals or wheelchair users to conveniently use access authorization kiosks.

[0045] The terms or words used in the present invention described below should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.
[0046] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely preferred embodiments of the present invention and do not represent all technical concepts of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.
[0047] FIG. 3 is an overall configuration diagram of a "voice recognition-based intelligent access authorization kiosk device" and an interlocking device according to a preferred embodiment of the present invention, and may include a visitor terminal (100), a visit reservation system (200), a database (210), an access authorization kiosk (300), and an access door control device (400).
[0048] The visitor terminal (100) is a terminal used by a visitor for a school visit, and it accesses a school visit website and requests a visit reservation registration using a school visit reservation application pre-installed on the terminal, and receives approval information when the visit is approved.
[0049] These visitor terminals (100) may use a personal computer (PC) or a mobile device such as a smartphone. If the visitor terminal is a personal computer, it may receive visit reservation approval information via email or PC notification, and if it is a mobile device, it may receive visit reservation approval information via KakaoTalk or text message. If the visit application is rejected, the rejection information may also be received via email or PC notification on the personal computer, or via notification talk or text message on the mobile device.
[0050] Although the present invention describes a visit reservation and access authorization kiosk using a school as an example, it is not limited thereto, and it will be obvious to those skilled in the art that it can be equally applied to all fields where visit reservations or visitor access are controlled using a kiosk.
[0051] The visit reservation system (200) processes visit reservations based on visitor information, transmits the visit reservation results to the visitor terminal (100), and provides visit information to the access authorization kiosk (300).
[0052] The database (210) serves to register visit information.
[0053] The door control device (400) functions to control the opening and closing of the door or the on / off of the door lock in conjunction with the above-mentioned access authorization kiosk (300).
[0054] The access authorization kiosk (300) automatically identifies visitors and selects a general guidance mode or a voice guidance mode according to the identified visitors to automatically control the visit approval process and access authorization of the visitors.
[0055] As illustrated in FIG. 4, such an access authorization kiosk (300) may include a user identification unit (310) for identifying a visitor, a voice recognition unit (330) for recognizing a visitor's voice input through a microphone (320), and an access control unit (340) that controls a guidance mode based on visitor identification information recognized through the user identification unit (310) and automatically performs visit approval processing and access control based on the voice recognized through the voice recognition unit (330).
[0056] Preferably, the user identification unit (310) can photograph a visitor approaching an access authorization kiosk through an artificial intelligence (AI) camera and analyze the captured visitor image to identify a general person, a visually impaired person, or a wheelchair user.
[0057] The voice recognition unit (330) performs processing to convert the voice language of a visitor input through the microphone (320) into character data that can be interpreted by a computer, and can use an algorithm such as a conventional HMM (Hidden Markov Model).
[0058] Preferably, the access control unit (340) may include a user identification information receiving module (341) that receives user identification information obtained through the user identification unit (310) as illustrated in FIG. 5, a user identification module (342) that identifies whether the user is a general person, a visually impaired person, or a wheelchair user based on the user identification information, and a guidance mode control module (343) that automatically controls a general guidance mode or a voice guidance mode to perform guidance according to the visitor identified by the user identification module (342).
[0059] Here, the guidance mode control module (343) can provide guidance through a general guidance mode if the identified visitor is a general person, and automatically switch to a voice guidance mode to provide voice guidance if the identified visitor is a visually impaired person or a wheelchair user.
[0060] In addition, the above guidance mode control module (343) can perform voice guidance by lowering the voice guidance speed by a certain speed compared to the voice speed of the general guidance mode when the guidance mode is a voice guidance mode.
[0061] Preferably, the access control unit (340) may include a visitor information verification module (344) that, upon obtaining visitor information through voice recognition, links with a visitor reservation system based on the visitor information to verify whether the visitor is a reserved visitor or a general visitor, an access control module (345) that generates an access authorization control signal based on the result verified by the visitor information verification module (344), and an emergency situation processing module (346) that processes an emergency situation based on the visitor information verified by the visitor information verification module (344) or performs emergency situation processing if it is determined to be an emergency situation through voice recognition.
[0062] Preferably, the access authorization kiosk (300) may include a visit information verification unit (360) that checks visit information by linking with a visit reservation system (200) based on recognized visitor information, an emergency situation processing unit (370) that handles the emergency situation by automatically calling an administrator or generating an alarm sound when it is determined that the visit information verification result or voice recognition result is an emergency situation, and an access control signal output unit (380) that transmits an access authorization control signal of the access control unit (340) to a door control device (400).
[0063] Preferably, the access authorization kiosk (300), although not shown in the drawing, may further include a visitor pass printing unit that prints a visitor pass allowing a visitor to visit the school in conjunction with the access control unit (340).
[0064] The operation of the "voice recognition-based intelligent access authorization kiosk device" according to the present invention configured as described above is specifically explained as follows.
[0065] First, a visitor who wishes to visit the school accesses the school visit website using a school visit reservation application pre-installed on the visitor terminal (100) and requests to register for a visit reservation.
[0066] When requesting a visit appointment here, you must enter visit information including the date and time of the visit, name, purpose of the visit (information about the teacher in charge may also be included), and phone number. In addition, you must complete an identity verification process using an identity authentication system prior to requesting a visit appointment. Various known identity authentication systems may be used for this verification process.
[0067] When visit information is entered as described above and a visit reservation is requested through the school visit website, the visit reservation system (200) receives the visit reservation information through the network.
[0068] When a school visit request occurs in accordance with the application for a visit reservation, the visit reservation system (200) assigns a teacher in charge, processes the visit approval or rejection based on the visit permission or denial information transmitted from the teacher in charge terminal, and performs an internal approval procedure to transmit the processing result to the visitor terminal (100).
[0069] For example, the visit reservation system (200) receives the visit reservation registration information through a network and analyzes the visit purpose information included in the visitor's visit information to assign a teacher in charge. Here, if a request for an interview with a specific teacher in charge is made in the visit purpose information, that teacher in charge is assigned as the teacher in charge.
[0070] When a teacher in charge is assigned, the visit reservation system (200) transmits visit information to the teacher in charge's terminal and requests a reply regarding permission or denial of the visit.
[0071] When the teacher in charge receives school visit request information through communication with the visit reservation system (200) via the teacher in charge terminal, the teacher checks the visit schedule or purpose, and provides information regarding whether the visit is permitted or denied. That is, if the teacher can consult with the visitor according to the schedule of the visit information, a positive response to the reply request is considered as simply granting permission for the visit. Conversely, if the teacher in charge cannot consult with the visitor according to the schedule of the visit information, the teacher denies the visit in response to the reply request. In this case, when the visit is denied, the teacher briefly records the reason for the denial, generates information regarding the denial of visit, and transmits it to the visit reservation system (200).
[0072] The visit reservation system (200) receives information regarding visit approval or denial through the teacher terminal in charge. Then, if the received information is visit approval information, it generates visit approval information and sends it to the visitor terminal (100) via a pre-registered visitor email, smartphone notification, text message, etc.
[0073] Thus, the visitor can recognize that the visit has been approved in accordance with the school visit reservation application through the visitor terminal (100).
[0074] Meanwhile, if the teacher in charge refuses to allow a visit, the visit reservation system (200) generates visit rejection information based on the received information regarding the inability to visit and transmits this to the visitor terminal (100) so that the visitor is aware that the visit application has been rejected. Here, the visit rejection information may include details such as the fact that counseling on the relevant date is difficult due to the teacher in charge's schedule, or other information regarding available counseling schedules predetermined by the teacher in charge.
[0075] Based on this visit rejection information, the visitor can apply for a revisit.
[0076] When a visit reservation is confirmed, the visit reservation system (200) transmits visitor information to the teacher in charge's terminal so that the teacher in charge is aware of the visit reservation information.
[0077] Meanwhile, visitors visit the school according to a set schedule after their visit is approved.
[0078] Previously, visitors would operate an access authorization kiosk to obtain approval, and then enter the campus once the door opened. However, even if a visit reservation had been made in advance, visually impaired or wheelchair users had to operate the access authorization kiosk themselves. Since the keypad and authentication control locations were installed based on the standards for the general public, there was inconvenience in operation.
[0079] To improve this, the present invention automatically identifies the visitor in the user identification unit (310) when the visitor approaches the shooting range of the entry / exit authorization kiosk (300).
[0080] That is, the user identification unit (310) photographs a visitor approaching an access authorization kiosk through an artificial intelligence (AI) camera and analyzes the captured visitor video to identify whether the visitor is a general person, a visually impaired person, or a wheelchair user. Here, the video analysis involves extracting objects from the captured video, extracting the outlines of the extracted object information, and determining whether a wheelchair is present based on the outline information. If a wheelchair is identified through this video analysis, the visitor is recognized as a visitor using a wheelchair. Furthermore, if it is determined that the visitor is not a wheelchair user through object extraction and outline extraction for video analysis, a face image is extracted from the captured video, an image of the eye area is extracted from the extracted face image, and then the presence or absence of sunglasses and the state of the eyelids are checked to determine whether the visitor is a general person or a visually impaired person. Here, the technology for extracting the image of the eye area and determining the state of the eyelids can utilize the technology used to analyze a driver's video in a vehicle to determine whether the driver is drowsy.
[0081] Through this video analysis, it is determined whether the visitor is a wheelchair user, a visually impaired person, or a general person, and the visitor identification information is transmitted to the access control unit (340).
[0082] The user identification information receiving module (341) of the access control unit (340) receives user identification information obtained through the user identification unit (310) and transmits it to the user identification module (342).
[0083] The user identification module (342) determines whether the user is a general person, a visually impaired person, or a wheelchair user based on the user identification information, and transmits the determined user identification information to the guidance mode control module (343).
[0084] The above guidance mode control module (343) automatically controls the general guidance mode or voice guidance mode based on the visitor identification information identified by the user identification module (342) to perform guidance for entry authorization control.
[0085] For example, if the identified visitor is a general visitor, the guidance mode control module (343) performs guidance through the general guidance mode. Here, the general guidance mode is a mode that guides a series of processes, such as processing visit approval for a reservation visitor or a general visitor at a standard access authorization kiosk, printing a visitor pass, and controlling the opening and closing of the door.
[0086] In addition, if the aforementioned identified visitor is visually impaired or a wheelchair user, it automatically switches to voice guidance mode and performs voice guidance.
[0087] Here, if the visitor guidance mode is voice guidance mode, voice guidance is performed at a speed lowered by a certain amount compared to the voice speed of the general guidance mode.
[0088] That is, the guidance mode control module (343) outputs the guidance voice slowly by lowering the speed of the guidance voice for visit guidance in voice guidance mode slightly compared to the speed of general voice guidance.
[0089] The visit guidance voice output in voice guidance mode is processed by a normal sound processing method through the guidance voice output unit (350) and then transmitted through the speaker (351).
[0090] Therefore, when a visually impaired person or a wheelchair user approaches the access authorization kiosk (300) to visit the school, the voice guidance mode is automatically activated so that they can receive visit guidance without operating the kiosk separately.
[0091] The voice guidance may include voice guidance to confirm whether the visitor is a reservation visitor or a walk-in visitor when visiting the school, and voice guidance information to state the name of the reservation holder aloud if the visitor is a reservation visitor.
[0092] When such voice guidance is transmitted through the speaker (351), the visually impaired or wheelchair user visiting the site says in voice whether they are a reservation visitor or a walk-in visitor, and if they are a reservation visitor, they say their name.
[0093] When a visitor's voice is generated, the microphone (320) receives it and transmits it to the voice recognition unit (330).
[0094] The voice recognition unit (330) recognizes the visitor's voice using an algorithm such as a Hidden Markov Model (HMM), which is a conventional voice recognition technique, and transmits the recognition result as data to the access control unit (340).
[0095] When the visit information verification module (344) of the access control unit (340) obtains visitor information through voice recognition, it verifies whether the visitor is a reserved visitor or a general visitor by linking with the visit reservation system (200) based on the visitor information.
[0096] That is, the visit information verification unit (360) transmits visitor information by linking with the visit reservation system (200) based on visitor information and requests whether a reservation exists. In response to this request, the visit reservation system (200) searches the database (210) using visitor information as a search term to check whether a visit reservation has been registered. Then, it transmits the verification result to the visit information verification unit (360). The visit information verification unit (360) transmits the transmitted visitor verification information to the access control unit (340).
[0097] The visit information verification module (344) of the access control unit (340) checks the visit verification information and, if it is a reserved visitor, transmits the information that it is a valid reserved visitor to the access control module (345). If it is not a reserved visitor, it checks the information that it is an on-site visitor and notifies the guidance mode control module (343). If it is an on-site visitor, it provides information and performs authentication processing as before, and then prints a visitor pass.
[0098] The access control module (345) outputs the visit in conjunction with the visitor pass output unit when the visitor is a reservation visitor, and also generates an access signal and transmits it to the access control signal output unit (380).
[0099] The above access control signal output unit (380) transmits an access signal to the door control device (400) so that the door opens automatically.
[0100] Visitors should wear their printed visitor pass, and enter the campus once the entrance door opens automatically.
[0101] As a result, if a reservation visitor is visually impaired or a wheelchair user, visit guidance is automatically provided via contactless voice without the need to operate the kiosk, and reservation confirmation, access pass printing, and door opening / closing are performed automatically, thereby enhancing convenience for visitors who have difficulty operating the kiosk.
[0102] Meanwhile, another feature of the present invention is that emergency situations can be handled using an access authorization kiosk (300).
[0103] For example, if a visitor or a user approaching the access / authorization kiosk speaks of an emergency situation in voice, the voice recognition unit (330) recognizes this, and if the emergency situation processing module (3460) of the access / authorization unit (340) recognizes it as an emergency situation, it automatically generates an alarm or calls a manager to enable real-time response to the emergency situation.
[0104] Through this emergency situation handling function, an external user can transmit the emergency situation through the access authorization kiosk (300) in case of an emergency, enabling real-time response to the emergency situation. In the event that an emergency occurs within the school, etc., if a student or teacher speaks the emergency situation in voice, it is recognized through voice recognition, and then an alarm is triggered or an administrator is called to respond to the emergency situation in real time, thereby ensuring safety.
[0105] According to the present invention described above, by automatically identifying visitors based on artificial intelligence (AI) and switching to voice mode when a visually impaired person or wheelchair user is present to process visits and grant access authorization through voice guidance, it is possible to improve management efficiency through contactless access processing and enhance user convenience and accessibility.
[0106] In addition, according to the present invention, by processing automatic visits and access authorizations in a contactless manner, user convenience can be enhanced while simultaneously reducing the workload of the manager.
[0107] Although the invention made by the inventors has been specifically described according to the above embodiments, it is obvious to those skilled in the art that the invention is not limited to the above embodiments and can be modified in various ways without departing from the gist thereof.
