Abstract
Description
Technology Field
[0001] The present invention relates to a device, system, and method for processing the exemption of parking fees for visiting vehicles using a wall pad (100) installed in a household within a multi-unit housing complex. More specifically, the invention relates to a technical field that provides visitor parking convenience directly at the household level without going through the management office by allowing a resident to directly input the vehicle number of a visiting vehicle through the touchscreen interface of the wall pad (100) within the household to query the parking history of the vehicle in real time from a parking management server (200) within the complex, and immediately process the settlement of the parking fee for the vehicle to zero (0) won through the explicit approval of the resident. Background Technology
[0003] In multi-unit housing complexes such as apartments, officetels, and row houses, a license plate recognition device (300) and a vehicle barrier (400) equipped with License Plate Recognition (LPR) technology are typically installed at the entrance of the complex to manage entry and exit by distinguishing between registered resident vehicles and unregistered external vehicles. If external vehicles visiting the complex use the parking lot beyond the allowed free parking time, parking fees are incurred, and methods for processing exemptions for these fees are emerging as a key element of multi-unit housing management services.
[0004] In conventional apartment complex parking management systems, the process for exempting visitor vehicles from parking fees typically follows a method where a resident reports the vehicle's license plate number by visiting the management office in person or by phone, after which a staff member manually enters the information into the system. However, this method is limited to operating hours, making it impossible to process exemptions for vehicles visiting at night, on holidays, or on weekends, or resulting in visitors unfairly incurring parking fees. Furthermore, the system presents issues such as the inconvenience of residents having to contact the management office directly, the potential for errors and processing delays due to manual handling, and security vulnerabilities as resident fee exemption requests are processed verbally without authentication.
[0005] Some apartment complexes are introducing a system where visitor vehicle license plates are pre-registered on the complex's server via smartphone applications. While this method has the advantage of automating the passage of visitor vehicles through barriers, it is subject to the prerequisite that registration must be completed prior to the visit; therefore, it cannot be applied in cases of sudden visits or situations where visitor vehicle information cannot be known in advance. Furthermore, it does not support a function to retroactively exempt parking fees for visitor vehicles that have already entered the complex, nor does it provide a means for residents to check in real-time how much the visitor vehicle is incurring in parking fees.
[0006] Existing wall pad (100) linked parking systems are limited to providing access control-centered functions, such as displaying entry notifications for resident vehicles or pre-registered visitor vehicles on the household screen, or allowing a resident to approve passage through the barrier by entering the visitor vehicle number. These systems are not directly linked to the settlement of parking fees for visitor vehicles and do not provide structural means for a resident to directly exercise the right to exempt from parking fees from the household terminal.
[0007] In the commercial sector, systems are in operation to provide parking fee discounts or waivers to service users based on barcode receipts or QR codes; however, this differs fundamentally from the structure in multi-unit housing, where residents directly exercise the right to exempt visitors on a household basis, in terms of operating entities, scope of authority, and technical architecture. The parking discount system in commercial facilities operates by having service providers apply discounts to an unspecified number of customers in bulk, with a separate discount terminal—rather than a household terminal—acting as the trigger for the fee exemption.
[0008] Therefore, there is an urgent need for a new technology that allows a resident to directly input the license plate number of a visiting vehicle on the wall pad (100) inside the household, check the real-time parking history of the vehicle, and then immediately process the exemption of parking fees according to the resident's explicit intent. The problem to be solved
[0010] The first problem that the present invention aims to solve is to provide visitor parking convenience 24 hours a day, 365 days a year without time constraints by allowing a resident of a multi-unit dwelling to directly process the exemption of parking fees for visiting vehicles from a wall pad (100) installed in the household without going through the management office.
[0011] The second problem that the present invention aims to solve is to provide an environment in which a resident can actively decide whether to grant an exemption based on sufficient information by allowing the resident to check parking history information, such as the time of entry, parking location, and current accumulated parking fee of the vehicle, in real time on the wall pad (100) screen before designating the vehicle eligible for exemption.
[0012] The third problem that the present invention aims to solve is to institutionally prevent the abuse of the parking fee exemption function by setting a monthly limit on the number of exemptions per household and a valid time range for exemption applications, and to ensure the fair operation of the complex's shared parking lot and the reasonable distribution of shared management fees.
[0013] The fourth problem that the present invention aims to solve is to innovate the user experience by linking the processing of parking fee exemptions with household intercom call events or front door opening events, so that residents can exempt parking fees for visiting vehicles with minimal operation without navigating separate menus.
[0014] The fifth problem that the present invention aims to solve is to detect abnormal exemption patterns in real time to issue security alerts, and to flexibly respond to various living situations involving multiple visiting vehicles, such as family events, through the transfer of exemption limits between households and proxy exemption functions for adjacent households. means of solving the problem
[0016] In order to solve the above-mentioned first to fifth problems, the present invention provides the following means.
[0017] A wall pad-based visitor vehicle parking fee exemption device according to the first means of the present invention comprises: an input unit (110) that receives a vehicle number of a visitor vehicle from a resident; a communication unit (130) that transmits the entered vehicle number to a parking management server (200) within the complex and receives parking history information; a display unit (120) that displays the parking history information on a screen and receives an exemption approval input from a resident; and a control unit (140) that requests a zero (0) won settlement from the parking management server (200) when the exemption approval input is received.
[0018] A wall pad-based visitor vehicle parking fee exemption system according to the second means of the present invention comprises: a wall pad (100) that performs functions of entering a visitor vehicle number, checking parking history, and approving exemption; a parking management server (200) that performs zero-won settlement according to a request from the wall pad (100), equipped with a parking history database (210), an exemption history database (220), a list of regular visitors (230), a household exemption limit management unit (240), an abnormal pattern detection module (250), and a fee settlement processing unit (260); a vehicle number recognition unit (300) that extracts the number of an entering vehicle; and a vehicle barrier (400) that automatically opens upon exit in response to a zero-won settlement completion signal.
[0019] A method for exempting a visitor vehicle from parking fees using a wall pad according to the third means of the present invention comprises: receiving a vehicle number through a touchscreen interface of a wall pad (100); searching for and returning the parking history of the vehicle in a parking management server (200); the wall pad (100) displaying the parking history and receiving an exemption approval from a resident; the parking management server (200) updating the settlement fee to zero (0) won; and the vehicle barrier (400) automatically opening when the vehicle exits. Effects of the invention
[0021] According to the present invention, since a resident of a multi-unit dwelling can directly exempt the parking fee for a visiting vehicle from the wall pad (100) within the household without the procedure of visiting or calling the management office, a visitor parking convenience service is provided at all times of the 24 hours, including nights and holidays. This provides the effect of fundamentally resolving the inconvenience of visitors caused by visiting outside the operating hours of the management office.
[0022] According to the present invention, since the resident can check the entry time, parking location, and current accumulated parking fee of a visiting vehicle in real time on the wall pad (100) screen before the exemption approval, the resident can proactively decide whether to grant an exemption based on sufficient information. Unlike a simple number registration method, this provides a structure in which the resident exercises active decision-making while aware of the status of parking fee accrual, thereby increasing the resident's participation in parking lot management.
[0023] According to the present invention, a monthly exemption limit is set per household, thereby structurally preventing specific households from abusing the parking fee exemption function. Furthermore, by operating multi-layered control mechanisms, such as the time range for applying for exemption and the recalculation of excess charges when the allowed free time is exceeded after exemption, a fair order of use for the shared parking lot is maintained and the rational distribution of shared management fees is realized.
[0024] According to the present invention, through a one-touch exemption function linked to a household intercom (900) call event and an automatic pop-up exemption suggestion function linked to a front door lock (800) opening event, a resident can naturally process a parking fee exemption during the process of responding to visitors. This provides the effect of significantly shortening the operation steps compared to the existing menu-based operation method and innovating the user experience. In particular, the configuration in which the household intercom (900) call and the parking fee exemption processing are integrated into a single interaction is an original technical configuration that has not been disclosed or implied in any prior known technology, and corresponds to a non-obvious combination of the call flow and the fee settlement flow.
[0025] According to the present invention, an abnormal pattern detection module (250) detects in real time excessive exemption requests within a unit of time, repeated exemptions for the same vehicle, and concentrated exemptions during late-night hours, and transmits an alarm to an administrator terminal (600), thereby providing a security effect that blocks attempts to abuse organized parking fee exemptions at an early stage. This abnormal pattern detection function is a configuration that fuses a parking fee settlement system with a security audit system, and represents a technological advancement that had not been conceived in the field of conventional simple fee exemption technology.
[0026] According to the present invention, by providing a function for transferring exemption limits between households and a function for proxy exemption by an adjacent household (700), residents can flexibly manage exemption limits even in situations where a large number of visiting vehicles occur simultaneously, such as during celebratory events or parties. In particular, the configuration in which an adjacent household (700) exempts visiting vehicle fees on behalf of an absent household institutionalizes the culture of mutual cooperation within a multi-unit housing community into a technological system, thereby presenting a new paradigm for trust-based services among residents within the complex.
[0027] Regarding the inventive step of the present invention, conventional apartment parking management systems are designed for the purpose of "barrier control" and adopt a structure that opens or maintains barriers by comparing a list of vehicles registered in advance by residents or managers with LPR recognition results. In contrast, the present invention presents a completely new technical objective of "resident-led post-entry fee nullification" and constitutes a unique architecture in which a household terminal, a parking fee settlement system, and a resident approval interface are combined in a trinity. This combination is a non-obvious technical configuration that is difficult to achieve by a technician in the field of access control technology merely by referencing the field of fee settlement technology. Even if a person skilled in the art mechanically combines known technologies, it is not easy to arrive at the comprehensive technical configuration of the present invention, which includes a series of control flows such as "real-time resident inquiry → explicit approval → immediate zero-won settlement → automatic opening of exit," as well as the accompanying limit management, anomaly detection, event linkage, and inter-household cooperation.

Specific details for implementing the invention
[0030] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. In describing the present invention, detailed descriptions of related known technologies are omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the present invention.
[0031] Referring to FIG. 1, a wall pad-based visitor vehicle parking fee exemption system according to one embodiment of the present invention comprises a wall pad (100), a parking management server (200), a vehicle license plate recognition device (300), a vehicle barrier (400), a visitor mobile phone (500), an administrator terminal (600), an adjacent household wall pad (700), a front door lock (800), and an intercom (900). These components are interconnected via a network (N) within the complex and communicate with the visitor mobile phone (500) and a remote mobile app via a connection to an external internet network. The network (N) within the complex may include wired Ethernet, Wi-Fi, or an in-household home network bus (RS-485, etc.), and a mixed configuration thereof is also possible.
[0032] Referring to FIG. 2, the wall pad (100) includes an input unit (110), a display unit (120), a communication unit (130), a control unit (140), a storage unit (150), an intercom linkage module (160), a door lock linkage module (170), and a biometric authentication module (180).
[0033] The input unit (110) is a means for receiving the vehicle number of a visiting vehicle from a resident and can be implemented as a touchscreen type soft keyboard, a physical button, a voice recognition module, or a combination thereof. The input unit (110) selectively supports a full number input mode for receiving the entire vehicle number and a partial number input mode for receiving only a part of the vehicle number (e.g., the last 4 digits) to list multiple candidate vehicles. The partial number input mode is designed to account for situations where it is difficult to accurately convey the entire number when a visitor verbally informs a resident of the vehicle number. When the input unit (110) receives the last 4 digits, the parking management server (200) returns a list of all incoming vehicles containing the corresponding 4 digits, and the flow proceeds to a point where the resident selects a target vehicle from the list displayed on the display unit (120).
[0034] The display unit (120) is implemented as a touchscreen display and outputs various interface screens such as a parking history lookup result, an exemption approval screen, a screen for selecting full exemption options and excess exemption options, an exemption completion notification screen, an anomaly detection alarm screen, and a popup suggesting registration of regular visitors. The parking history information displayed on the display unit (120) includes the vehicle number of the vehicle, a thumbnail image of the vehicle at the time of entry captured by the vehicle number recognition device (300), the time of entry, the parking location (floor, zone, number), the current accumulated parking fee, and the remaining free parking allowance time, thereby allowing the resident to decide whether to grant an exemption based on sufficient information.
[0035] The communication unit (130) is a means for communicating with the parking management server (200), adjacent household wall pad (700), manager terminal (600), and external internet network through the complex network (N), and may include a wired LAN interface and a Wi-Fi module. The communication unit (130) transmits an inquiry request signal, an exemption request signal, an exemption cancellation request signal, a regular visitor registration request signal, a limit transfer request signal, and a proxy exemption request signal to the parking management server (200), and receives parking history information, an exemption completion signal, a limit exceeding notification, an anomaly detection alarm signal, and a regular visitor registration proposal signal from the parking management server (200).
[0036] The control unit (140) is implemented as a processor that integrates and controls the input unit (110), display unit (120), communication unit (130), storage unit (150), intercom linkage module (160), door lock linkage module (170), and biometric authentication module (180). When the control unit (140) receives an exemption approval input from a resident, it may require additional authentication through the biometric authentication module (180) according to a pre-set security level, and transmits an exemption request signal to the parking management server (200) through the communication unit (130) only if the additional authentication is successful. Additionally, the control unit (140) performs a remote delegation approval function that generates an exemption request signal by verifying a delegation approval response received from a remote mobile app.
[0037] The storage unit (150) is implemented as non-volatile memory that stores generation identification information, a list of regular visitors, an exemption history cache, a security level setting value, and a setting value for the time range at which exemption applications can be made. The list of regular visitors stored in the storage unit (150) is periodically synchronized with the list of regular visitors (230) of the parking management server (200).
[0038] The intercom linkage module (160) receives a visitor call signal from the complex entrance lobby phone or the unit entrance intercom (900) and transmits it to the control unit (140). Upon receiving the call signal, the control unit (140) activates the call screen and simultaneously requests a list of external vehicles that have recently entered the area near the entrance of the building within a pre-set time from the parking management server (200), and displays the received list of candidate vehicles as a list of exemption candidates on the display unit (120) within the call screen. When a resident selects the vehicle during the call and inputs the exemption button with a single touch, the control unit (140) immediately generates an exemption request signal and transmits it to the parking management server (200) via the communication unit (130). This implements a one-touch exemption function in which the call and exemption processing are completed within a single interaction.
[0039] The door lock interlock module (170) receives a door opening event from the front door lock (800) and transmits it to the control unit (140). Upon receiving the door opening event, the control unit (140) checks the parking management server (200) for the existence of a new external vehicle that entered within the previous pre-set time, and if the vehicle exists, automatically displays a pop-up screen on the display unit (120) that queries whether to exempt the vehicle along with the vehicle list. When a resident selects the target vehicle and enters confirmation, the control unit (140) generates and transmits an exemption request signal.
[0040] The biometric authentication module (180) may include a fingerprint recognition sensor, a face recognition camera, or an iris recognition sensor, and performs additional authentication according to the instructions of the control unit (140) when a request for a high-security grade exemption is made. The authentication failure history of the biometric authentication module (180) is recorded in the storage unit (150), and if authentication fails more than a preset number of times, the control unit (140) stops the temporary exemption function of the corresponding generation and sends a security alert to the administrator terminal (600).
[0041] Referring to FIG. 3, the parking management server (200) includes a parking history database (210), an exemption history database (220), a list of regular visitors (230), a household exemption limit management unit (240), an abnormal pattern detection module (250), a fee settlement processing unit (260), and a communication interface (270).
[0042] The parking history database (210) stores the entry time, exit time, entry image, vehicle number, parking location, accumulated parking fee, and settlement fee of all vehicles within the complex. The parking history database (210) is equipped with an index that supports high-speed search by vehicle number and also supports Like search by partial number (4 digits). The entry image stored in the parking history database (210) is transmitted to the display unit (120) of the wall pad (100) so that a resident can visually compare the actual vehicle of the visitor with the entry image.
[0043] The exemption history database (220) stores the vehicle number for which exemption processing has been completed, information on the household requesting exemption, the time of exemption processing, the original parking fee exempted, the exemption method (full amount / excess amount), whether the exemption was canceled, and the exemption authentication method (direct approval by resident / remote delegated approval / exemption by proxy of an adjacent household). The exemption history database (220) is used to generate exemption history statistics reports by household and period in response to a request from the administrator terminal (600). Residents can view the exemption history associated with their household through the wall pad (100).
[0044] The regular visitor list (230) stores the vehicle number and registration date of regular visitors registered by household. When a vehicle registered in the regular visitor list (230) enters, the fee settlement processing unit (260) automatically sets the parking fee of the vehicle to zero (0) won, the household exemption limit management unit (240) deducts the remaining exemption count of the household by one, and sends an automatic exemption processing notification to the wall pad (100) of the household.
[0045] The household exemption limit management unit (240) manages the pre-set monthly exemption limit and the remaining exemption limit for each household. The exemption limit is set according to the management regulations and can be adjusted via the administrator terminal (600). The household exemption limit management unit (240) resets the remaining exemption limit to the standard limit at midnight on the 1st of every month, and performs a process of deducting the remaining limit of the transferor household and adding the remaining limit of the recipient household when processing the transfer of limits between households. In addition, both the automatic exemption for regular visitors and the direct exemption for residents are deducted from the same limit pool, ensuring consistent management.
[0046] The abnormal pattern detection module (250) analyzes exemption history data by generation in real time to detect abnormal patterns such as excessive exemption requests within a unit of time, repeated exemptions for the same vehicle number, concentrated exemptions during late-night hours, and exemption requests after authentication failure. When an abnormal pattern is detected, the abnormal pattern detection module (250) sends an abnormal detection notification to the wall pad (100) of the corresponding generation and simultaneously sends a security alarm message to the administrator terminal (600), and temporarily suspends the processing of additional exemptions for that generation on the same day. The abnormal pattern detection module (250) can continuously improve detection accuracy by applying a machine learning-based abnormal detection algorithm.
[0047] When the fee settlement processing unit (260) receives an exemption request signal from the wall pad (100), it checks the remaining number of exemptions in the household exemption limit management unit (240), and only if there are remaining numbers, it updates the settlement fee for the corresponding vehicle in the parking history database (210) to zero (0). In the case of a full exemption request, all accumulated parking fees are updated to zero (0), and in the case of an excess exemption request, only the excess fee excluding the fee within the basic free parking time is updated to zero (0). After the fee settlement processing unit (260) completes the update of the settlement fee, it transmits a free exit permission signal for the corresponding vehicle number to the vehicle barrier (400), transmits an exemption completion notification to the wall pad (100) of the corresponding household, and if the visitor's mobile phone (500) is registered, it transmits an SMS or push notification containing an exemption completion message and exit guidance information.
[0048] The communication interface (270) is a means of communicating with the wall pad (100), vehicle number recognition device (300), vehicle barrier (400), manager terminal (600), and adjacent household wall pad (700) through the network (N) within the complex, and may use TCP / IP-based socket communication, REST API, or MQTT protocol.
[0049] A vehicle number recognition device (300) is installed at the entrance to photograph the license plate area of an incoming vehicle and performs optical character recognition (OCR) processing on the captured image to extract a vehicle number string. To maintain a high recognition rate even in poor environments such as night, rain, or backlight, the vehicle number recognition device (300) may apply infrared lighting, a high-sensitivity image sensor, and a deep learning-based license plate recognition algorithm. The vehicle number recognition device (300) transmits the extracted vehicle number string and the incoming vehicle image to a parking management server (200) so that they are recorded in a parking history database (210).
[0050] The vehicle barrier (400) is installed at the entrance and opens or maintains the barrier bar according to a signal received from the parking management server (200). After the fee settlement processing unit (260) completes the zero (0) won settlement for a specific vehicle and transmits a signal allowing free exit, when the vehicle approaches the exit area, the vehicle number recognition unit (300) recognizes the vehicle number and the vehicle barrier (400) automatically opens the barrier bar. When the barrier bar is opened, the vehicle barrier (400) transmits the exit time of the vehicle to the parking management server (200) to update the exit time field of the parking history database (210).
[0051] Hereinafter, the basic exemption processing flow according to the first embodiment of the present invention will be described in detail with reference to FIGS. 4 and FIGS. 5.
[0052] When a resident selects the visitor vehicle fee exemption menu on the display unit (120) of the wall pad (100), a vehicle number input screen is activated on the input unit (110). When the resident selects the full number input mode to input the vehicle number of the visitor vehicle, or selects the partial number input mode to input the last four digits, the control unit (140) transmits a parking history inquiry request signal containing the corresponding vehicle number to the parking management server (200) via the communication unit (130). When the communication interface (270) of the parking management server (200) receives the inquiry request, the fee settlement processing unit (260) searches the parking history database (210) for the record of the currently parked vehicle that matches the corresponding vehicle number (or partial number). In the case of a full number inquiry, a single result is returned, and in the case of a partial number inquiry, a list of multiple candidate vehicles is returned. The returned parking history information includes the vehicle number, time of entry, parking location, current accumulated parking fee, and an entry image thumbnail.
[0053] The control unit (140) of the wall pad (100) displays the received parking history information on the display unit (120). In the case of partial number lookup, a list of multiple candidate vehicles is displayed, and the resident selects a target vehicle from the list. Subsequently, the display unit (120) displays a screen for selecting an exemption method that includes a full exemption option and an excess exemption option. The full exemption is a method of treating all accumulated parking fees for the vehicle as zero (0), and the excess exemption is a method of treating only the excess amount, excluding the fee corresponding to the basic free parking time, as zero (0). When the resident selects an exemption method, the display unit (120) displays a final confirmation screen, and when the resident presses the confirmation button, the exemption approval is completed. In the case of households with a high security level, additional authentication by a biometric authentication module (180) may be required after pressing the confirmation button.
[0054] When the exemption approval is completed, the control unit (140) transmits an exemption request signal containing the vehicle number, exemption method, and household identification information to the parking management server (200) via the communication unit (130). The fee settlement processing unit (260) of the parking management server (200) checks the remaining number of exemptions for the household in the household exemption limit management unit (240), and if the remaining number is 1 or more, updates the settlement fee for the vehicle in the parking history database (210) to zero (0) won and deducts 1 from the remaining number of exemptions. The fee settlement processing unit (260) records the exemption processing history in the exemption history database (220), transmits a signal allowing the vehicle to exit for free to the vehicle barrier (400), and transmits an exemption completion notification to the wall pad (100). If the visitor's mobile phone (500) is registered in advance, the fee settlement processing unit (260) transmits a parking fee exemption completion message and exit guidance to the number.
[0055] Referring to FIG. 8, the flow of a pre-exemption reservation for a non-entering vehicle according to a second embodiment of the present invention is described. When a resident requests a search by entering the vehicle number of a visiting vehicle, but there is no entry record of the vehicle in the parking history database (210), the parking management server (200) transmits a non-entering status response to the wall pad (100). When the control unit (140) receives the non-entering status response, it displays a pre-exemption reservation inquiry popup on the display unit (120) to inquire with the resident whether to register the vehicle number in the pre-exemption reservation list. If the resident selects pre-registration, the control unit (140) transmits a request for pre-exemption reservation registration of the vehicle number to the parking management server (200) via the communication unit (130). The fee settlement processing unit (260) stores the vehicle number in the pre-exemption reservation list, and when the entry of the vehicle is detected by the vehicle number recognition unit (300), the fee for the vehicle is automatically set to zero (0) in the parking history database (210), and the household exemption limit management unit (240) deducts one time from the remaining exemption count of the household. The pre-exemption reservation validity period can be set by the resident, and if there is no entry of the vehicle for the validity period, the reservation is automatically expired.
[0056] Referring to FIG. 9, the one-touch exemption flow for intercom (900) call linkage according to the third embodiment of the present invention is described. When a visitor call signal is received from the entrance lobby phone or the apartment entrance intercom (900), the intercom linkage module (160) transmits it to the control unit (140). The control unit (140) activates the call screen on the display unit (120) and simultaneously requests a list of external vehicles that newly entered the parking management server (200) within the previous pre-set time (e.g., 10 minutes) near the entrance of the building via the communication unit (130). The fee settlement processing unit (260) of the parking management server (200) extracts and returns a list of vehicles that satisfy the corresponding conditions from the parking history database (210), and the control unit (140) displays this as an exemption candidate list on the display unit (120) within the call screen. When a resident selects a visiting vehicle from a candidate list during a call and presses the exemption button with a single touch, the control unit (140) immediately generates an exemption request signal and transmits it to the parking management server (200), and when the exemption processing is completed, displays an exemption completion icon on the call screen. This allows the resident to obtain a one-touch experience of processing the parking fee exemption while simultaneously talking with a visitor.
[0057] Referring to FIG. 10, the flow of an automatic exemption proposal linked to an opening event of a front door lock (800) according to the fourth embodiment of the present invention is described. When the door lock linkage module (170) receives a door opening event from the front door lock (800), it transmits it to the control unit (140). The control unit (140) inquires with the parking management server (200) via the communication unit (130) whether there is a newly entered external vehicle within a pre-set time (e.g., 15 minutes) prior to the time of receiving the door opening event. If the vehicle exists, the control unit (140) automatically displays a pop-up screen on the display unit (120) that queries whether to exempt the parking fee, along with a list of the newly entered vehicles. When a resident selects the target vehicle on the pop-up screen and enters confirmation, an exemption request signal is generated and processed. If the resident closes the pop-up screen or does not respond within a certain period of time, the pop-up is automatically removed, and the screen returns to the state after normal door lock opening. In this embodiment, the physical event of door opening functions as a natural trigger for parking fee exemption processing, allowing residents to provide parking convenience while simultaneously responding to visitors without navigating a separate menu.
[0058] Referring to FIG. 15, the flow of automatic exemption for regular visitors and automatic suggestion based on visit pattern analysis according to the fifth embodiment of the present invention is described. When a resident performs an input to register a specific vehicle number as a regular visitor through the input unit (110) of the wall pad (100), the control unit (140) requests the registration of the corresponding vehicle number in the regular visitor list (230) of the parking management server (200) through the communication unit (130). Subsequently, when the vehicle enters the complex, the vehicle number recognition unit (300) extracts the vehicle number and transmits it to the parking management server (200), and the fee settlement processing unit (260) searches for the corresponding vehicle number in the regular visitor list (230). If it matches, the fee settlement for the vehicle is automatically set to zero (0) won in the parking history database (210) without any separate operation by the resident, and the household exemption limit management unit (240) deducts the remaining exemption count for the household by one and transmits an automatic exemption processing notification to the wall pad (100) of the household.
[0059] Additionally, the parking management server (200) periodically analyzes the exemption history database (220) and, if an exemption has been performed for the same vehicle number in the same household more than a set number of times (e.g., 3 times) within a set period, identifies the vehicle number as a candidate for a regular visitor and sends a notification proposing registration as a regular visitor to the wall pad (100) of the household. When the resident accepts the registration proposal, the vehicle number is automatically added to the list of regular visitors (230). This function minimizes the burden of operation on the resident by completely automating the processing of exemptions for regularly visiting vehicles, such as caregivers, housekeepers, and family members who visit frequently.
[0060] Referring to FIG. 13, the flow of transferring the exemption limit between households according to the 6th embodiment of the present invention is described. When a resident of a specific household has insufficient remaining exemption counts for the current month due to reasons such as celebratory events or parties, the resident performs a request input to transfer a portion of the remaining exemption counts to another household (receiving household) within the same complex through the input unit (110) of the wall pad (100). The control unit (140) transmits a limit transfer request signal to the parking management server (200) through the communication unit (130), the signal including transferor household identification information, recipient household identification information, and the number of transfers. The communication interface (270) of the parking management server (200) sends a notification to the wall pad (100) of the recipient household asking whether to accept the transfer, and when the resident of the recipient household enters an acceptance response, the household exemption limit management unit (240) subtracts the number of transfers from the remaining number of exemptions of the transferor household, adds the number of transfers to the remaining number of exemptions of the recipient household, and records the transfer history in the exemption history database (220). This allows for a flexible response to situations where a large number of visiting vehicles occur temporarily through mutual cooperation among residents within the complex.
[0061] Referring to FIG. 14, the flow of proxy exemption for an adjacent household (700) according to the 7th embodiment of the present invention is described. When all residents of a specific household go out and the household is absent, the wall pad (700) of the adjacent household (700) designated in advance by the household performs the role of proxy exemption. When a vehicle with a visit reservation for the household enters the parking management server (200), the server determines that the household is absent and sends a proxy exemption request notification to the wall pad (700) of the adjacent household (700) designated in advance. When the resident of the adjacent household (700) approves the proxy exemption request on the notification screen displayed on the display unit (120), the fee settlement processing unit (260) of the parking management server (200) deducts one time from the exemption limit of the original visiting household and processes the parking fee for the vehicle as zero (0) won. The history of proxy exemption processing is recorded in the exemption history database (220), and the resident of the absent household can check the proxy exemption history through the wall pad (100) after returning home.
[0062] Referring to FIG. 12, the abnormal exemption pattern detection and alarm flow according to the eighth embodiment of the present invention is described. An abnormal pattern detection module (250) of a parking management server (200) monitors exemption history recorded in the exemption history database (220) in real time. The abnormal pattern detection module (250) determines an abnormal pattern if exemption requests are made more than a preset number of times (e.g., 5 times) within a unit time (e.g., 1 hour) from the same household, if multiple exemptions are requested within the same day for the same vehicle number from the same household, if exemptions occur intensively during late-night hours (e.g., 23:00 to 06:00), or if exemption requests occur continuously after a biometric authentication failure. When an abnormal pattern is detected, the abnormal pattern detection module (250) transmits an abnormal detection notification message to the wall pad (100) of the household and simultaneously transmits a security alarm message containing household information, the type of abnormal pattern, and the time of occurrence of the abnormal pattern to the administrator terminal (600), and temporarily suspends additional exemption processing for the household on that day. The administrator can review the abnormal event through the administrator terminal (600) and decide whether to release the pause.
[0063] According to another embodiment of the present invention, when a fee settlement processing unit (260) receives a request for cancellation of exemption from the wall pad (100) of the household after the zero (0) won settlement for a specific vehicle has been completed and the vehicle has not yet been discharged, it restores the settlement fee of the vehicle to the original accumulated parking fee prior to the exemption processing, restores the remaining number of exemptions per household that was deducted by one, and records the cancellation history in the exemption history database (220). This function responds to situations where exemption is canceled due to a resident's mistake or change of mind, and ensures the consistency and integrity of the system through the processing of restoring the number of exemptions.
[0064] According to another embodiment of the present invention, the fee settlement processing unit (260) calculates a pre-set free parking allowance time (e.g., 2 hours) based on the time when zero (0) won settlement for a specific vehicle is completed, and if the vehicle's exit is not detected by the vehicle number recognition unit (300) even after the time has elapsed, the parking fee is recalculated by applying a pre-set excess fee unit price to the amount exceeding the allowance time. The recalculated excess fee and the exit guidance message are transmitted to the wall pad (100) of the household and the visitor's mobile phone (500), respectively, to prevent a situation where the visitor occupies the parking indefinitely.
