Description

Visiting vehicle access control device and method

[0001] This specification relates to a device for managing the entry and exit of unregistered vehicles, and more specifically, to a technology that facilitates intercom calls between the driver of a visiting vehicle and a parking lot manager or security guard when entering a parking lot.

[0002] When visiting a building with a shared parking lot, such as an apartment or building, drivers press the call button on the intercom installed near the parking lot entrance barrier to speak to a security guard. They then state the purpose of their visit and the destination they're visiting. This allows them to gain entry and enter the parking lot. However, for drivers still in their cars, the call button is quite a distance away, requiring them to exit the car or lean out the window to press it, which can be inconvenient.

[0003] Furthermore, after speaking with the visitor (driver), the security guard inputs the visitor's destination into the parking management system and then issues a command to open the parking lot barrier, allowing the visitor's vehicle to enter the parking lot. This process requires the security guard to input each destination individually, confirm the destination, and then manually input the barrier opening command. This presents a problem in that it hinders smooth vehicle entry when the entry queue is long or when the security guard is absent.

[0004] The above-described content is only intended to help understand the background technology for the technical ideas of the present invention, and therefore cannot be understood as content corresponding to prior art known to those skilled in the art in the technical field of the present invention.

[0005] The present specification is intended to solve the above-mentioned problem, and one embodiment of the present specification aims to detect an attempt to make an intercom call by a driver of a visiting vehicle without the driver getting out of the vehicle or leaning out the window to press the call button of the intercom, and to connect the intercom call to the parking lot manager.

[0006] In addition, one embodiment of the present specification aims to automatically obtain the destination information and open the parking lot entrance barrier to allow entry of the visiting vehicle without the security guard having to input the destination information of the visiting vehicle into the parking management system one by one and directly input an opening command for the parking lot entrance barrier.

[0007] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0008] The present specification proposes a visiting vehicle access control device. The visiting vehicle access control device comprises: a sensor unit for detecting an intercom call attempt by a driver of a vehicle through a visitor intercom based on an image recognition result or a proximity detection result; a communication unit for providing a call session for a call between the visitor intercom and a security office intercom; and a control unit for transmitting a control command for opening a parking lot entry barrier to a parking lot access controller that controls the opening and closing of the parking lot entry barrier when receiving an entry permission signal from the security office intercom or obtaining visit information from the driver's voice obtained through the call session; wherein, when the control unit receives a message from the parking lot access controller that a vehicle not listed on the entry permission list has approached the parking lot entry barrier, the control unit can provide the call session based on a detection result of the sensor unit.

[0009] Meanwhile, the present specification proposes a method for controlling access of visiting vehicles. The method for controlling access of visiting vehicles may include: when a message is received from a parking lot access controller that controls the opening and closing of a parking lot entry barrier, notifying that a vehicle approaching the parking lot entry barrier is not registered in the entry permit list; preparing a call session for a call between a visitor intercom and a security office intercom; when an intercom call attempt by the driver of the vehicle is detected through the visitor intercom based on an image recognition result or a proximity detection result, connecting a call with the security office intercom through the call session; and when an entry permit signal is received from the security office intercom or visit information is obtained from the driver's voice obtained through the call session, transmitting a control command to the parking lot access controller to open the parking lot entry barrier.

[0010] On the other hand, the present specification proposes a visiting vehicle access control device. The visiting vehicle access control device comprises: a sensor unit that detects a vehicle in front of a parking lot entry barrier based on an image recognition result or a proximity detection result; a communication unit that provides a call session for a call between a driver and a security office intercom; and a control unit that, when receiving an entry permission signal from the security office intercom or obtaining visit information from the driver's voice obtained through the call session, transmits a control command to open the parking lot entry barrier to a parking lot access controller that controls the opening and closing of the parking lot entry barrier; wherein, when the control unit receives a message from the parking lot access controller indicating that a vehicle not listed in the entry permission list has stopped in front of the parking lot entry barrier for at least a predetermined period of time, the control unit can provide the call session.

[0011] The embodiment disclosed herein has the effect of detecting an attempt to make an intercom call by a driver of a visiting vehicle and connecting the intercom call to a parking lot manager without the driver of the visiting vehicle getting out of the vehicle or leaning out the window to press the call button on the intercom at the entrance of the parking lot.

[0012] In addition, the disclosed embodiment of the present specification has the effect of automatically obtaining the destination information and then opening the parking lot entry barrier to allow entry of the visiting vehicle without the security guard having to input the destination information of the visiting vehicle into the parking management system one by one and directly inputting an opening command for the parking lot entry barrier.

[0013] Meanwhile, the effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0029]

[0030] Hereinafter, a method for managing access of a visiting vehicle according to an embodiment of the present invention will be described with reference to the attached drawing 1.

[0031] FIG. 1 is a drawing illustrating the concept of a method for managing access to a visiting vehicle by a visiting vehicle access control device according to one embodiment.

[0032] For example, a parking lot entrance / exit control device (100), a parking lot entry barrier (200), and a parking lot exit barrier (300) may be installed at the parking lot entrance / exit.

[0033] The visiting car access control device (100) is equipped with an intercom for visitors, and allows communication between the driver of the car and the security guard through the intercom.

[0034] The parking lot entry barrier (200) opens and closes the gate by the opening and closing control signal of the visiting vehicle entry and exit management device (100).

[0035] The visiting vehicle access control device (100) identifies a vehicle approaching the parking lot entry barrier (200) through an equipped sensor, and if the identified vehicle is listed on the entry permission list, opens the gate to allow the vehicle to enter, and if the vehicle is not listed on the entry permission list, blocks the vehicle from entering.

[0036] When a sensor equipped in a visiting vehicle access control device (100) recognizes that a driver of a vehicle stopped in front of a parking lot entry barrier (200) rolls down the driver's side window of the vehicle or extends an arm toward the visiting vehicle access control device (100) and places a hand (10) thereon, the visiting vehicle access control device (100) determines that the driver wants to talk to a security guard via an intercom, and can connect a call between the security office intercom and the visitor intercom.

[0037] According to an embodiment, the visiting vehicle access control device (100) can connect the visitor intercom and the guard station intercom even if a vehicle whose entry is blocked by the parking lot entry barrier (200) remains in that spot for a certain period of time. That is, the visiting vehicle access control device (100) can automatically connect a call between the visitor intercom and the guard station intercom after a predetermined period of time (e.g., 3 seconds) when a vehicle not listed on the entry permission list approaches the parking lot entry barrier (200) and stops.

[0038] When the visiting vehicle access control device (100) receives an entry approval message from the security office after a conversation with the driver (hereinafter, the terms driver and visitor may be used interchangeably) via the intercom, it transmits a control command to the parking lot entry barrier (200) to open the gate. The parking lot entry barrier (200) opens the gate according to the received control command to allow the visiting vehicle to enter the parking lot.

[0039] When a message indicating that the security guard is absent is received or when a call is attempted but the call is not connected within a certain period of time, the visiting vehicle access control device (100) outputs a guidance message requesting the visitor to input visit information via voice or text through the visitor intercom, and obtains visit information such as the purpose of the visit and the place of visit from the driver's voice response, and then transmits a control command to open the gate. Meanwhile, the visiting vehicle access control device (100) may converse with the driver through an artificial intelligence-based voice chatbot instead of the guidance message, obtain visit information such as the purpose of the visit and the place of visit from the driver's voice response, and then transmit a control command to open the gate.

[0040] The parking lot exit barrier (300) is equipped with a vehicle blocking gate and allows vehicles to exit the parking lot according to the opening / closing control signal of the visiting vehicle entry / exit management device (100).

[0041] Hereinafter, a method for managing the entry and exit of a visiting vehicle according to an embodiment of the present invention will be described in detail with reference to the attached drawings 2 to 9.

[0042] FIG. 2 is a drawing illustrating the configuration of a visiting vehicle access control system including a visiting vehicle access control device according to one embodiment.

[0043] A visiting vehicle access control system (1000) may be configured to include a visiting vehicle access control device (100), a parking lot entry barrier (200), a parking lot exit barrier (300), and a security office intercom (400).

[0044] A parking lot entry barrier (200) may be configured to include a parking lot entry control unit (210), a vehicle detection unit (220), and a vehicle information acquisition unit (230).

[0045] When a car entering a parking lot approaches a parking lot entry barrier (200) and stops in front of it, a car detection unit (220) detects the approach of the car and notifies the parking lot access control unit (210) of the car's approach. The car detection unit (220) can detect whether a car is approaching the parking lot entry barrier (200) or whether a car is present in front of the parking lot entry barrier (200) using an ultrasonic sensor, radar, lidar, ToF sensor, or the like.

[0046] The parking lot access control unit (210) commands the vehicle information acquisition unit (230) to capture the license plate number of a parked vehicle. The parking lot access control unit (210) identifies the license plate number information from the captured license plate image through image recognition and determines whether the vehicle is listed on the access permit list. Depending on the embodiment, the vehicle information acquisition unit (230) may be an RFID reader, in which case the vehicle can be identified by recognizing an RFID card installed in the vehicle. In this case, the license plate number of the vehicle that is permitted to enter is registered in the access permit list.

[0047] In addition, the parking lot access control unit (210) can command the vehicle information acquisition unit (230) to capture the entire exterior of a parked vehicle. The parking lot access control unit (210) identifies the type of vehicle through image recognition in the captured image of the vehicle and determines whether the corresponding type of vehicle is listed on the entry permit list. At this time, the entry permit list includes the types or categories of vehicles permitted to enter. For example, the types / categories of vehicles may include the types and categories of vehicles whose purpose of entry can be identified through exterior recognition, such as delivery vehicles, taxis, and educational institution vehicles such as school buses.

[0048] If a car entering the parking lot is not listed on the entry permit list, the parking lot access control unit (210) notifies the visiting car access control device (100) of this fact.

[0049] The visiting vehicle access control device (100) may include a device configuration of a visitor intercom, and may connect a call between the visitor intercom and the security office intercom (400) when it detects the driver's hand or the vehicle window being lowered. When the visiting vehicle access control device (100) receives an entry approval message from the security office intercom (400), it may transmit a control command to the parking lot access control unit (210) to open the gate to allow the vehicle to pass.

[0050] In addition, according to an embodiment, the visiting vehicle access control device (100) can automatically connect the visitor intercom and the security office intercom (400) when a vehicle whose entry is blocked by the parking lot entry barrier (200), i.e., a vehicle not listed on the entry permit list, stays in front of the parking lot entry barrier (200) for a certain period of time.

[0051] FIG. 3 is a block diagram illustrating a configuration of a visiting vehicle access control device according to one embodiment.

[0052] Referring to FIG. 3, the vehicle access control device (100) may be configured to include a camera (110), a microphone (120), a speaker (130), a display unit (140), a sensor unit (150), a communication unit (160), a storage unit (170), an alarm unit (180), and a control unit (190). The illustrated components are not essential, and the vehicle access control device (100) may be implemented to have more or fewer components. Some of the above components may constitute an intercom for visitors that allows the driver to communicate with the security office. For example, the intercom for visitors may be configured to include a camera (110), a microphone (120), a speaker (130), and a display unit (140).

[0053] Hereinafter, the components of the above-mentioned visiting vehicle access control device (100) will be described.

[0054] The camera (110) can capture images of a driver (visitor). Specifically, the camera (110) is installed so that its shooting direction is directed toward the driver's seat of a vehicle parked in front of the parking lot entry barrier (200) of FIG. 1, and has an angle of view that includes all windows of the driver's seat of the vehicle.

[0055] The microphone (120) can acquire the driver's voice. The microphone (120) can have directionality and can be installed with a configuration that can sufficiently receive the voice of the driver riding in the vehicle.

[0056] The speaker (130) can output a waiting tone when a call is connected to the security room intercom, and can also output a voice received from the security room intercom. In addition, the speaker (130) can also output a pre-stored guidance voice.

[0057] The display unit (140) can display guidance text. In addition, the display unit (140) can output an image received from the guard station intercom, and can also be combined with a touchpad to display an input interface for receiving input from the driver. The guidance text can be text explaining the actions that the driver must take to connect the guard station intercom in front of the visiting vehicle access control device (100), and can also include a graphic image representing the actions. For example, the display unit (140) can display the text "If you wish to make an intercom call, place your palm on the recognition unit." along with an image of a palm.

[0058] The sensor unit (150) may include a proximity detection sensor, an image sensor, and a distance measurement sensor. The sensor unit (150) may detect the driver's attempt to make an intercom call based on the proximity detection result, or may detect the driver's attempt to make an intercom call based on the image recognition result. Any sensor that can detect when a part of the driver's body approaches within a certain distance from the sensor unit (150), such as a ToF (Time of Flight) sensor or an ultrasonic sensor, may be used as the proximity detection sensor. In addition, since the ToF sensor can obtain depth information of an object, it may be used as a part of the image sensor. Meanwhile, the ToF sensor may be used as the distance measurement sensor. Since the ToF sensor can obtain depth information of an object, it can measure the distance to the interior of the vehicle beyond the glass window when the driver's window is opened. Therefore, the ToF sensor can determine whether the driver has lowered the window to make an intercom call.

[0059] FIG. 4 is a diagram showing an example of image recognition and proximity detection according to one embodiment, and an example of proximity detection and image recognition is described with reference to FIGS. 3 and 4.

[0060] For example, the sensor unit (150) can detect when a part of the driver's body, such as the driver's palm, approaches within a certain distance using the proximity detection sensor. In addition, if the proximity detection sensor is a ToF sensor, depth information about the detection target object can be obtained, so the sensor unit (150) can obtain a three-dimensional image of the shape of the detection target object, i.e., the shape of the palm. Accordingly, the sensor unit (150) can also determine that the palm approaches the sensor unit (150). As illustrated in FIG. 4(a), when the driver of the vehicle extends his or her arm out of the window (410) and brings the palm (430) close to the proximity detection sensor (420) of the sensor unit (150) within a certain distance (D), the proximity detection sensor (420) detects the palm (430).

[0061] As another example, the sensor unit (150) can capture a certain area including the driver's seat of a visiting vehicle parked next to the visiting vehicle access control device (100) using the image sensor, and can recognize that the driver's seat window of the vehicle is lowered through image recognition. That is, as illustrated in FIG. 4(b), the image sensor (421) of the sensor unit (150) captures the driver's seat window (410) of the vehicle, and can recognize that the closed window (410) is lowered through image recognition.

[0062] In addition, as another example, the sensor unit (150) can recognize a part of the body, such as the driver's face or hand shape, based on image recognition. For example, the sensor unit (150) can recognize a person's palm or a person's face in an image captured of a certain area including the driver's seat. As illustrated in FIG. 4(c), the image sensor (421) of the sensor unit (150) can capture a picture of a person sitting in the driver's seat and recognize the hand shape (430), or as illustrated in FIG. 4(d), the image sensor (421) of the sensor unit (150) can capture a picture of the driver's seat and recognize the person's face (440). The image sensor (421) can include a ToF sensor as part of its configuration, and can further utilize the 3D depth information about the driver's face or hand acquired from the ToF sensor to acquire more accurate image data about the driver's hand shape (430) or the person's face (440).

[0063] In addition, as a distance measuring sensor of the sensor unit (150), the ToF sensor can recognize that the driver's side window (410) of a closed vehicle is lowered, as illustrated in FIG. 4(b). When the closed driver's side window (410) is lowered, the space blocked by the window glass opens, resulting in a significant change in the distance measurement value of the ToF sensor. Therefore, the ToF sensor can detect that the driver's side window (410) is closed and then opened.

[0064] The communication unit (160) can establish a call session with the security room intercom (400 in FIG. 2), and transmit the driver's video and voice acquired through the camera (110) and microphone (120) to the security room intercom through the call session, and conversely, can receive the call video and voice received from the security room intercom.

[0065] The storage unit (170) can store a program for the operation of the control unit (190) and temporarily store input / output data. In addition, the storage unit (170) can store data generated by the visiting vehicle access control device (100), acquired image / audio data, and data input from the outside.

[0066] The alarm unit (180) can output an alarm message to be delivered to the driver, and can deliver the driver's call as an alarm message to the security office intercom.

[0067] The control unit (190) can control the components of the visiting vehicle access control device (100) to perform the functions of each component.

[0068] When the control unit (190) receives a message from the parking lot entry barrier (200 in FIG. 2) that a vehicle not listed in the entry permission list has approached the parking lot entry barrier, the control unit (190) controls the communication unit (160) based on the detection result of the sensor unit (150) to provide a call session with the security office intercom. For example, when the control unit (190) receives a message that a vehicle not listed in the entry permission list has approached the parking lot entry barrier, if the sensor unit (150) recognizes that the driver's window is lowered, recognizes a part of the driver's body such as the driver's face or hand, or detects that a part of the driver's body such as the driver's palm is approaching within a certain distance, as in the example described above, the control unit determines that the driver wants to talk to the security guard at the security office through the intercom and provides a call session with the security office intercom through the communication unit (160).

[0069] The control unit (190) may transmit a control command to the parking lot access control unit (210 in FIG. 2) to open the gate when receiving an entry permission signal from the security office intercom or obtaining visit information from the driver's voice acquired through the call session. However, when the control unit (190) receives a message indicating that the guard is absent or when attempting to connect a call to the security office intercom through the communication unit (160) but the call is not connected within a certain period of time, the control unit (190) recognizes that the guard is absent and outputs a guidance message requesting the driver to input visit information via voice or text through the visitor intercom, thereby allowing the driver to input visit information via voice. In this case, the control unit (190) may obtain visit information such as the purpose of the visit and the visit location from the driver's voice response and then transmit a control command to open the gate of the parking lot access control unit. Meanwhile, an artificial intelligence-based voice chatbot may be used instead of a voice guidance message. The control unit (190) may converse with the driver via a voice chatbot, obtain visit information such as the purpose of the visit and the location of the visit from the driver's voice responses, and then transmit a control command to open the gate. For example, the voice chatbot may obtain the building number and room number of the desired visit and the purpose of the visit, such as a business meeting, a visit to a facility within the building, or a visit for repairs, through a conversation with the driver, and then, if the obtained information is analyzed and it is determined that the gate needs to be opened, notify the control unit (190) to open the gate. The voice chatbot may be an artificial intelligence-based voice chatbot trained to obtain visit information, including the location and purpose of the visit, from the driver through a conversation. In addition, the voice chatbot may compare the visit information with a pre-registered database to determine whether the purpose of the visit of the visiting vehicle is valid, and based on the determination result, approve the entry of the visiting vehicle.The database may contain information on the tenants of the building where the device is installed, such as the building and unit number, information on the occupied commercial space, and information on the occupied facilities. Furthermore, the database may contain information on business meetings of tenants of the building where the device is installed, and information on visit plans by outsiders. Accordingly, the voice chatbot may compare the visit information obtained from the driver with the pre-registered database to determine whether the driver's visit information is appropriate, and based on the determination result, transmit a signal to the control unit (190) to approve the entry of the visiting vehicle.

[0070] The visiting vehicle access control device (100) may include an AI device as a separate device to process the aforementioned image recognition and voice recognition procedures.

[0071] Figure 5 is a block diagram of an AI device according to one embodiment.

[0072] The AI ​​device (1920) of FIG. 5 may include an electronic device including an AI module capable of performing AI processing, or a server including the AI ​​module. In addition, the AI ​​device (1920) may be included as part of at least a portion of the visiting vehicle access control device (100) illustrated in FIG. 3, and may be configured to perform at least a portion of the AI ​​processing process.

[0073] The AI ​​processing of the AI ​​device (1920) may include all operations related to the control of the control unit (190) illustrated in FIG. 3, all operations for image recognition through artificial intelligence learning, and all operations related to conversations with the driver through a voice chatbot. For example, the visiting car access control device (100) may process collected image data with an AI-based object recognition model to perform operations such as recognizing that a car window is lowered or that a person in the driver's seat is extending an arm and bringing their palm close to themselves. The AI ​​device (1920) may be included as a component of the control unit (190) illustrated in FIG. 3.

[0074] The above AI device (1920) may include an AI processor (1921), a memory (1925) and / or a communication unit (1927).

[0075] The AI ​​device (1920) is a computing device capable of learning a neural network, and may be implemented as various electronic devices such as a server, desktop PC, notebook PC, tablet PC, etc., or may be implemented as a single chip. In the present invention, the AI ​​device (1920) may be a visiting vehicle access control device (100) implemented in the form of any one of the various electronic devices.

[0076] The AI ​​processor (1921) can learn a neural network using a program stored in the memory (1925). In particular, the AI ​​processor (1921) can learn a neural network for recognizing device-related data. Here, the neural network for recognizing device-related data can be designed to simulate the structure of the human brain on a computer and can include a plurality of network nodes having weights that simulate neurons of a human neural network. The plurality of network modes can each exchange data according to a connection relationship so as to simulate the synaptic activity of neurons that exchange signals through synapses. Here, the neural network can include a deep learning model developed from a neural network model. In the deep learning model, the plurality of network nodes can be located in different layers and exchange data according to a convolution connection relationship. Examples of neural network models include various deep learning techniques such as deep neural networks (DNNs), convolutional neural networks (CNNs), recurrent neural networks (RNNs), restricted Boltzmann machines (RBMs), deep belief networks (DBNs), and deep Q-networks, and can be applied to fields such as computer vision (CV), speech recognition, natural language processing, and speech / signal processing.

[0077] Meanwhile, the processor performing the functions described above may be a general-purpose processor (e.g., CPU), but may also be an AI-specific processor for artificial intelligence learning (e.g., GPU).

[0078] The memory (1925) can store various programs and data required for the operation of the AI ​​device (1920). The memory (1925) can be implemented as a non-volatile memory, a volatile memory, a flash memory, a hard disk drive (HDD), a solid state drive (SDD), etc. The memory (1925) is accessed by the AI ​​processor (1921), and data reading / recording / modifying / deleting / updating, etc. can be performed by the AI ​​processor (1921). In addition, the memory (1925) can store a neural network model (e.g., a deep learning model (1926)) generated through a learning algorithm for data classification / recognition according to one embodiment of the present invention. The neural network model can include a large language model (LLM) for driving a voice chatbot.

[0079] Meanwhile, the AI ​​processor (1921) may include a data learning unit (1922) that learns a neural network for data classification / recognition. The data learning unit (1922) may learn criteria regarding which learning data to use to determine data classification / recognition and how to classify and recognize data using the learning data. The data learning unit (1922) may acquire learning data to be used for learning and apply the acquired learning data to the deep learning model, thereby learning the deep learning model.

[0080] The data learning unit (1922) may be manufactured in the form of at least one hardware chip and mounted on the AI ​​device (1920). For example, the data learning unit (1922) may be manufactured in the form of a dedicated hardware chip for artificial intelligence (AI), or may be manufactured as a part of a general-purpose processor (CPU) or a graphics processor (GPU) and mounted on the AI ​​device (1920). In addition, the data learning unit (1922) may be implemented as a software module. When implemented as a software module (or a program module including instructions), the software module may be stored in a non-transitory computer-readable medium that can be read by a computer. In this case, at least one software module may be provided by an operating system (OS) or an application (application program).

[0081] The data learning unit (1922) may include a learning data acquisition unit (1923) and a model learning unit (1924).

[0082] The learning data acquisition unit (1923) can acquire learning data required for a neural network model to classify and recognize data. For example, the learning data acquisition unit (1923) can acquire image data and / or sample data regarding transmitters on road infrastructure for input into the neural network model as learning data.

[0083] The model learning unit (1924) can use the acquired learning data to learn the neural network model to have a judgment criterion on how to classify a given data. At this time, the model learning unit (1924) can train the neural network model through supervised learning that uses at least some of the learning data as a judgment criterion. Alternatively, the model learning unit (1924) can train the neural network model through unsupervised learning that discovers a judgment criterion by learning on its own using the learning data without guidance. In addition, the model learning unit (1924) can train the neural network model through reinforcement learning that uses feedback on whether the results of the situation judgment according to the learning are correct. In addition, the model learning unit (1924) can train the neural network model using a learning algorithm including error back-propagation or gradient descent.

[0084] Once the neural network model is trained, the model training unit (1924) can store the trained neural network model in memory. The model training unit (1924) can also store the trained neural network model in the memory of a server connected to the AI ​​device (1920) via a wired or wireless network.

[0085] The data learning unit (1922) may further include a learning data preprocessing unit (not shown) and a learning data selection unit (not shown) to improve the analysis results of the recognition model or to save resources or time required for generating the recognition model.

[0086] The learning data preprocessing unit can preprocess the acquired data so that it can be used for learning to determine situations. For example, the learning data preprocessing unit can process the acquired data into a preset format so that the model learning unit (1924) can use the acquired learning data for learning to recognize image data for the transmitter.

[0087] Additionally, the learning data selection unit can select data required for learning from among the learning data acquired by the learning data acquisition unit (1923) or the learning data preprocessed by the preprocessing unit. The selected learning data can be provided to the model learning unit (1924). For example, the learning data selection unit can select only data included in a specific field as learning data by recognizing a specific field among the data set collected through the network.

[0088] Additionally, the data learning unit (1922) may further include a model evaluation unit (not shown) to improve the analysis results of the neural network model.

[0089] The model evaluation unit inputs evaluation data into the neural network model, and if the analysis results output from the evaluation data do not satisfy a predetermined standard, it can cause the model learning unit (1922) to relearn. In this case, the evaluation data may be predefined data for evaluating the recognition model. For example, the model evaluation unit can evaluate that the predetermined standard is not satisfied if the number or ratio of evaluation data with inaccurate analysis results among the analysis results of the learned recognition model for the evaluation data exceeds a preset threshold.

[0090] Meanwhile, the AI ​​device (1920) illustrated in FIG. 5 is functionally divided into an AI processor (1921), a memory (1925), a communication unit (1927), etc., but it should be noted that the aforementioned components may be integrated into one module and referred to as an AI module.

[0091] FIG. 6 is a drawing illustrating a method for managing access to a visiting vehicle by a visiting vehicle access control device according to one embodiment.

[0092] Referring to FIGS. 2, 3 and 6, the visiting vehicle access control device (100) first detects a vehicle that has entered in front of the parking lot entry barrier (200) (S610).

[0093] Next, the parking lot access control unit (210) of the visiting vehicle access control device (100) checks whether the entering vehicle is listed in the entry permission list based on the information on the entering vehicle acquired by the vehicle information acquisition unit (230) (S620).

[0094] When the visiting vehicle access control device (100) receives a message from the parking lot access control unit (210) that controls the opening and closing of the parking lot entry barrier (200) notifying that the vehicle approaching the parking lot entry barrier (200) is a vehicle listed on the entry permission list, a control command for controlling the opening of the gate of the parking lot entry barrier (200) is transmitted to the parking lot access control unit (210) to allow the vehicle to enter (S625).

[0095] On the other hand, if the visiting vehicle access control device (100) receives a message from the parking lot access control unit (210) that controls the opening and closing of the parking lot entry barrier (200) notifying that the vehicle approaching the parking lot entry barrier (200) is not listed on the entry permission list, the device detects the driver's intercom call attempt based on the image recognition or proximity detection result through the sensor unit (150), and if the driver's intercom call attempt is detected, prepares a call session for a call with the security office intercom (S630).

[0096] Next, if the visiting vehicle access control device (100) detects an intercom call attempt by the driver of the approaching vehicle based on image recognition or proximity detection, it connects a call with the guard station intercom through the call session (S640). Here, the visiting vehicle access control device (100) can connect a call with the guard station intercom through the call session if it recognizes that the window of the vehicle is lowered as a result of image recognition, if it recognizes a part of the driver's body such as the face or hand as a result of image recognition, if it detects that a part of the body is approaching within a certain distance as a result of proximity detection, or if it detects that the window of the vehicle is lowered as a result of distance measurement.

[0097] The visiting vehicle access control device (100) connects a call between the visitor intercom and the security office intercom to determine whether the driver can talk to the security office (S650), and if the call is received from the security office, connects the call to the security office (S660). Afterwards, upon receiving an entry permission signal from the security office intercom, a signal for controlling the opening of the gate of the parking lot entry barrier (200) is transmitted to the parking lot access control unit (210) to permit the vehicle to enter.

[0098] However, the visiting vehicle access control device (100) determines whether the driver can talk to the security office by connecting a call between the visitor intercom and the security office intercom (S650), and if the call to the security office is not connected, it operates a voice chatbot to conduct a conversation with the driver (S680). Thereafter, based on the conversation with the driver through the voice chatbot, it transmits a signal for controlling the opening and closing of the gate of the parking lot entry barrier (200) to the parking lot access control unit (210) (S690). That is, the visiting vehicle access control device (100) operates the voice chatbot through the call session, and when it obtains visit information such as visit location information or visit purpose information from the driver's voice obtained through the voice chatbot, it transmits a control command to open the gate of the parking lot entry barrier (200) to the parking lot access control unit (210). Specifically, when the visiting vehicle access control device (100) receives a message from the security office intercom indicating that the security guard is absent or when a call is not connected within a certain period of time after an attempt to connect a call, the device outputs a voice guidance message to have the driver input the purpose of the visit by voice or text, or converses with the driver through a voice chatbot, and when the device acquires visit information from the driver's voice input according to the voice guidance message or the conversation with the voice chatbot, the device transmits a control command to open the gate of the parking lot entry barrier (200) to the parking lot access control unit (210).

[0099] FIG. 7 is a drawing illustrating a method for managing access to a visiting vehicle by a visiting vehicle access control device according to another embodiment.

[0100] Referring to FIGS. 2, 3 and 7, when the visiting vehicle access control device (100) receives a message from the parking lot access control unit (210) that controls the opening and closing of the parking lot entry barrier (200) notifying that the vehicle approaching the parking lot entry barrier (200) is not listed on the entry permission list, the device prepares a call session for a call with the security office intercom (S710).

[0101] Next, when the visiting vehicle access control device (100) receives a message from the parking lot access controller that a vehicle not listed in the access permission list has stopped in front of the parking lot entry barrier for a certain period of time (e.g., 3 seconds), it connects a call with the guard room intercom through the call session (S720).

[0102] At this time, when the visiting vehicle access control device (100) receives an entry permission signal from the guardhouse intercom, or acquires visit information such as visit location information or visit purpose information from the driver's voice acquired through the call session, it transmits a control command to open the gate of the parking lot entry barrier (200) to the parking lot access control unit (210) (S730). Specifically, when the visiting vehicle access control device (100) receives a message from the guardhouse intercom indicating that the guard is absent or when the call is not connected within a certain period of time after a call connection attempt, it outputs a voice guidance message to have the driver input the purpose of the visit by voice or text, or converses with the driver through a voice chatbot, and when it acquires visit information from the driver's voice input according to the voice guidance message or the conversation with the voice chatbot, it transmits a control command to open the gate of the parking lot entry barrier (200) to the parking lot access control unit (210).

[0103] Meanwhile, the visiting vehicle access control device (100) can also be used when a vehicle is parked. Hereinafter, with reference to FIG. 8, a method for controlling the visiting vehicle access control device (100) when a vehicle is parked will be described.

[0104] FIG. 8 is a drawing illustrating a method for managing access to a visiting vehicle by a visiting vehicle access control device according to another embodiment.

[0105] Referring to FIGS. 2, 3, and 8, the visiting vehicle access control device (100) detects a vehicle entering the parking lot exit barrier (300) (S810). The vehicle entering the parking lot exit barrier (300) can be detected by the sensor unit (150) of the visiting vehicle access control device (100), a camera installed in the parking lot exit barrier (300), or a camera installed in a separate location around the device. The visiting vehicle access control device (100) can recognize the license plate number of the vehicle exiting the parking lot.

[0106] Next, the visiting vehicle access control device (100) checks whether the parking fee for the exiting vehicle has been paid (S820), and if it is determined that the parking fee has been paid, a control command for opening the gate of the parking lot exit barrier (300) is transmitted to the parking lot access control unit (210) to allow the vehicle to exit (S830).

[0107] On the other hand, the visiting vehicle access control device (100) can check whether the parking fee of the exiting vehicle has been paid (S820), and if it is determined that the parking fee has not been paid, a parking fee unpaid message can be output (S840). The parking fee unpaid message can be displayed on a display separately installed on the path that the vehicle exiting the parking lot takes. In this case, the camera that detects the exiting vehicle also needs to be installed far from the parking lot exit barrier (300) on the path that the vehicle exiting the parking lot takes, rather than being installed adjacent to the parking lot exit barrier (300), so that the driver can check whether the parking fee has been paid before reaching the gate of the parking lot exit barrier (300).

[0108] Next, the visiting vehicle access control device (100) operates a voice chatbot to conduct a conversation with the driver of a vehicle parked in front of the gate of the parking lot exit barrier (300) (S850). If the voice chatbot obtains settlement information through this conversation, it transmits a signal to open the gate of the parking lot exit barrier (300) to the parking lot access control unit (210) to allow the vehicle to exit. The settlement information can be extracted through the purchase or consumption history of the driver (visitor) within the building. For example, the voice chatbot asks the driver about the shopping history of a store within the building and receives a response related to the shopping from the driver. Next, the voice chatbot searches whether the shopping history exists in the store's sales history database, and if it determines that the shopping history exists, it allows the vehicle to exit the parking lot. Meanwhile, the settlement information can be extracted through the driver's (visitor's) movements within the building. The voice chatbot asks the driver about the location and purpose of their visit within the building and receives relevant responses from the driver. The voice chatbot then searches the building's visit schedule database to see if a meeting or visit to the location exists. If it determines that a visit record exists, it allows the vehicle to exit the parking lot. Therefore, the vehicle access control device disclosed herein can manage not only vehicle entry but also vehicle exit.

[0109] In the above description, the steps, processes, or operations may be further divided into additional steps, processes, or operations, or combined into fewer steps, processes, or operations, depending on the implementation of the present invention. Furthermore, some steps, processes, or operations may be omitted as needed, or the order of the steps or operations may be switched. Furthermore, each step or operation included in the aforementioned vehicle access control method may be implemented as a computer program and stored on a computer-readable recording medium, and each step, process, or operation may be executed by a computer device.

[0110]

[0111] The term "unit" as used herein (e.g., control unit, etc.) can mean a unit that includes one or a combination of two or more of hardware, software, or firmware, for example. "Unit" can be used interchangeably with terms such as unit, logic, logical block, component, or circuit, for example. "Unit" can be the smallest unit of an integrally formed component or a part thereof. "Unit" can also be the smallest unit that performs one or more functions or a part thereof. "Unit" can be implemented mechanically or electronically. For example, "unit" can include at least one of an application-specific integrated circuit (ASIC) chip, field-programmable gate array (FPGA), or programmable-logic device that performs certain operations, which are known or will be developed in the future.

[0112] At least a portion of a device (e.g., modules or functions thereof) or a method (e.g., operations) according to various embodiments may be implemented as instructions stored on a computer-readable storage medium, for example, in the form of a program module. When the instructions are executed by a processor, the one or more processors may perform a function corresponding to the instructions. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Computer-readable storage media / computer-readable recording media include hard disks, floppy disks, magnetic media (e.g., magnetic tape), optical media (e.g., compact disc read-only memory (CD-ROM), digital versatile disc (DVD), magneto-optical media (e.g., floptical disks), hardware devices (e.g., read-only memory (ROM), random access memory (RAM), or flash memory), and may also include those implemented in the form of carrier waves (e.g., transmitted via the Internet). In addition, program instructions may include not only machine language codes such as those generated by a compiler, but also high-level language codes that can be executed by a computer using an interpreter, etc. The above-described hardware devices may be configured to operate as one or more software modules to perform operations of various embodiments, and vice versa.

[0113] Modules or program modules according to various embodiments may include at least one or more of the aforementioned components, some of which may be omitted, or may further include other additional components. Operations performed by modules, program modules, or other components according to various embodiments may be executed sequentially, in parallel, iteratively, or heuristically. Additionally, some operations may be executed in a different order, omitted, or other operations may be added.

[0114] The term "a" as used herein is defined as one or more than one. Furthermore, the use of introductory phrases such as "at least one" and "one or more" in the claims, even if the same claim includes introductory phrases such as "at least one" and "one or more" and the ambiguous phrase "a," should not be construed to mean that the introduction of another claim element by the ambiguous phrase "a" limits any particular claim containing the introduced claim element to an invention containing only one such element.

[0115] In this document, expressions such as "A or B" or "at least one of A and / or B" may include all possible combinations of the items listed together.

[0116] Unless otherwise specified, terms such as "first" and "second" are used arbitrarily to distinguish between the elements they describe. Therefore, these terms are not necessarily intended to indicate temporal or other priority of such elements, nor does the mere fact that certain measures are recited in different claims indicate that a combination of such measures cannot be advantageously employed. Therefore, these terms are not necessarily intended to indicate temporal or other priority of such elements. The mere fact that certain actions are recited in different claims does not indicate that a combination of such actions cannot be advantageously employed.

[0117] Additionally, terms such as "front," "back," "top," "upper," "bottom," "bottom," "over," and "below" in the detailed description and claims are used for descriptive purposes and are not necessarily used to describe permanent relative positions. It is to be understood that such terms are interchangeable under appropriate circumstances, such that the embodiments of the invention described herein can operate in orientations other than those illustrated or otherwise described herein.

[0118] For simplicity and clarity, it should be understood that elements depicted in the drawings are not necessarily drawn to scale. For example, the dimensions of some elements may be exaggerated relative to others for clarity. Furthermore, where deemed appropriate, reference numbers may be repeated across the drawings to indicate corresponding or similar elements.

[0119] The arrangement of components to achieve the same function is effectively "related" to achieve the desired function. Therefore, any two components combined to achieve a specific functionality can be considered "related" to achieve the desired function, regardless of the structural or intermediary components. Similarly, two components thus associated can be considered "operably connected" or "operably coupled" to achieve the desired function.

[0120] Furthermore, those skilled in the art will recognize that the functional boundaries between the aforementioned operations are merely exemplary. Multiple operations may be combined into a single operation, a single operation may be divided into additional operations, and operations may be executed with at least partial temporal overlap. Furthermore, alternative embodiments may include multiple instances of a particular operation, and the order of the operations may be altered in various other embodiments. However, other modifications, variations, and alternatives are also possible. Accordingly, the detailed description and drawings should be considered in an illustrative rather than a restrictive sense.

[0121] The phrase "may be X" indicates that condition X may be satisfied. It also indicates that condition X may not be satisfied. For example, a reference to a system that includes a particular component must also include scenarios where the system does not include the particular component. For example, a reference to a method that includes a particular action must also include scenarios where the method does not include the particular component. However, to take another example, a reference to a system that is configured to perform a particular action must also include scenarios where the system is not configured to perform the particular task.

[0122] The terms "comprising," "having," "consisting of," "consisting of," and "consisting essentially of" are used interchangeably. For example, any method may include at least the acts described in the drawings and / or specification, or may include only the acts described in the drawings and / or specification. Furthermore, the word "comprising" does not exclude the presence of elements or acts listed in a claim.

[0123] Those skilled in the art will recognize that the boundaries between logical blocks are merely exemplary, and that alternative embodiments may merge logical blocks or circuit elements or impose alternative decompositions of functionality across various logical blocks or circuit elements. Therefore, it should be understood that the architecture depicted herein is merely exemplary, and that many other architectures that achieve the same functionality may be implemented.

[0124] Furthermore, for example, in one embodiment, the illustrated examples may be implemented as circuits located on a single integrated circuit or within the same device. Alternatively, the examples may be implemented as any number of individual integrated circuits or individual devices interconnected in any suitable manner, and other variations, modifications, variations, and alternatives are also possible. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.

[0125] Additionally, for example, the examples described above or portions thereof may be implemented as software or code representations of physical circuits or logical representations convertible to physical circuits, such as in any suitable type of hardware description language.

[0126] Furthermore, the present invention is not limited to physical devices or units implemented with non-programmable hardware, but may also be applied to programmable devices or units capable of performing desired device functions by operating in accordance with appropriate program code, such as mainframes, minicomputers, servers, workstations, personal computers, notepads, personal digital assistants (PDAs), electronic games, automobiles and other embedded systems, mobile phones and various other wireless devices, generally referred to herein as 'computer systems'.

[0127] The system, apparatus or device referred to in this specification includes at least one hardware component.

[0128] Connections as described herein may be any type of connection suitable for transmitting signals from or to each node, unit, or device, for example, via an intermediate device. Accordingly, unless explicitly stated otherwise, a connection may be, for example, a direct connection or an indirect connection. A connection may be described or illustrated with reference to a single connection, multiple connections, a unidirectional connection, or a bidirectional connection. However, different embodiments may vary the implementation of the connection. For example, separate unidirectional connections may be used instead of a bidirectional connection, or vice versa. Furthermore, multiple connections may be replaced by a single connection that transmits multiple signals sequentially or in a time-multiplexed manner. Similarly, a single connection transmitting multiple signals may be split into multiple connections that transmit subsets of those signals. Thus, numerous options exist for transmitting signals.

[0129] Preferred embodiments of the technology of this specification have been described above with reference to the attached drawings. The terms and words used in this specification and claims should not be construed as limited to their conventional or dictionary meanings, but rather should be interpreted in their meanings and concepts consistent with the technical spirit of the present invention.
