Resident-Exclusive Billing-Type Storage Management System for Multi-Dwelling Units Linked with Apartment Maintenance Fee Settlement System, and Method Thereof

Abstract

The present invention provides a management server comprising: an access control terminal installed at the entrance or individual storage locker of a warehouse provided within a multi-unit housing complex, which receives building and unit number information or an access authentication key from registered residents; an authentication management module that verifies household membership by comparing with a resident database and blocks access by unregistered non-residents; and a billing processing module that calculates usage fees based on warehouse usage history and links to automatically aggregate and bill the management fee settlement system. The warehouse serves as a long-term storage space exclusively for residents, distinct from parcel lockers, and can be installed in various locations such as underground parking lots, above-ground containers, or spaces adjacent to pilotis or corridors. The billing processing module supports a two-dimensional billing structure using continuous occupancy period, locker grade, and location grade as composite variables, a choice between monthly fixed-rate and pay-as-you-go options, an additional unit price for excess occupancy, and settlement based on deductions for shared rentals among residents. Through this, the effects of blocking unauthorized use by outsiders, eliminating the need for separate payment infrastructure, resolving non-payment risks through sanctions for overdue management fees, and improving the efficiency of integrated management office operations are achieved.

Description

Technology Field

[0001] The present invention relates to a system and method for managing the use of a warehouse provided within a multi-unit housing complex, and more specifically, to a resident-only billing warehouse management system and method for multi-unit housing that controls access so that only registered residents of the multi-unit housing can access the dedicated storage warehouse through a building and unit number-linked authentication procedure, and automatically adds and charges the usage fee based on the residents' warehouse usage history to the monthly management fee bill by directly linking it with the management fee settlement system of the multi-unit housing. Background Technology

[0003] With the increase in the domestic population living in multi-unit housing and the proliferation of single-person households and small-sized units, the problem of an absolute shortage of storage space within individual units is intensifying. Residents are frequently unable to store seasonal items, sports equipment, leftover moving goods, and large appliances within their units, leading them to rely on private self-storage services or leave their belongings abandoned by illegally occupying common hallways or underground parking lots. Such behavior has been pointed out as a factor that degrades the quality of community life, as it leads to violations of fire safety standards in common passageways, damages aesthetics, and causes inter-floor conflicts.

[0004] To address these issues, a business model involving the installation of private storage units for residents in idle underground parking spaces or common areas on the ground level within apartment complexes is gaining attention. However, existing unmanned storage devices (e.g., KR101127900B1) are designed to allow outsiders, including delivery personnel, to access the lockers if they obtain a tracking number or a temporary password, thus harboring inherent security vulnerabilities such as illegal intrusion by individuals posing as delivery personnel. Furthermore, since the system adopts a method of immediate payment via on-site currency readers, it incurs the cost of installing separate payment terminals, and there are issues with user convenience, as residents are unable to use the service if they do not carry cash or a card.

[0005] Meanwhile, the apartment management fee collection processing system (e.g., KR100860392B1) is a system specialized in the automatic calculation of existing items such as electricity, water, and common management fees, as well as the automation of bill issuance and collection, and does not include an interlocking structure that dynamically generates new service items and adds them to the current month's management fee. The waste collection billing system (e.g., KR100936519B1) is a method of immediately billing based on weight on a one-time usage event basis after user identification, and is fundamentally different from the complex billing structure of long-term collection services that are premised on continuous occupancy of space.

[0006] Therefore, there is a technical need for an integrated system that installs storage warehouses exclusively for residents of multi-unit housing within the complex, provides access control exclusively for residents that reuses existing access authentication infrastructure, and calculates charges based on complex variables such as occupancy period, locker grade, and location grade, and automatically aggregates charges by linking with the existing management fee settlement system without a separate payment infrastructure. The problem to be solved

[0008] The present invention was devised to solve the problems of the prior art as described above. First, it aims to structurally block unauthorized use by outsiders by allowing only registered residents of the apartment complex to access storage warehouses within the complex through unit number-linked authentication.

[0009] Second, the purpose is to maximize payment convenience for residents and minimize the burden of separate settlement work for the management office by automatically adding and billing the usage fees for residents' use of the storage facility to the existing management fee settlement system without the need for a separate payment terminal or independent payment application.

[0010] Third, it aims to respond to the storage needs and payment capabilities of various residents by providing a sophisticated billing structure that applies complex variables such as occupancy period, locker grade, installation location, and excess occupancy penalty.

[0011] Fourth, it aims to promote the efficient use of unused storage space by supporting a short-term shared rental function among residents. means of solving the problem

[0013] According to one aspect of the present invention for achieving the above objective, a billing-type warehouse management system for a multi-unit housing complex is provided, comprising: an access control terminal (100) installed at an entrance (420) or individual storage box (410) of a warehouse (400) provided within a multi-unit housing complex, which receives authentication information including building and unit number information or an access authentication key from a registered resident of the multi-unit housing complex; an authentication management module (210) which receives authentication information from the access control terminal (100), compares it with a resident database (211), controls the opening of the warehouse (400) or individual storage box (410) when authentication is completed, and refuses opening for access requests from unregistered non-residents; and a billing processing module (220) which calculates a usage fee based on the usage history of the warehouse (400) of the authenticated resident, transmits the calculated usage fee to a management fee settlement system (300), and links it so that it is automatically added to the current month's management fee bill for the corresponding building and unit number.

[0014] According to another aspect of the present invention, a method for managing a warehouse for a multi-unit dwelling is provided, which is performed by a computing device, and the method comprises the steps of: obtaining building and unit number or access authentication key information from a resident through an access control terminal (100) installed in a warehouse (400); performing authentication by comparing the obtained information with a resident database (211) and authorizing access to the warehouse; generating usage history data based on the user's warehouse (400) usage start and end times or individual storage locker (410) rental information; and calculating a usage fee based on the usage history data and transmitting it to a management fee settlement system (300) to automatically include it in the management fee bill for the corresponding building and unit number. Effects of the invention

[0016] According to the present invention, the following technical and commercial effects occur.

[0017] First, it has the effect of structurally blocking unauthorized use by outsiders. Conventional unmanned storage devices had inherent security vulnerabilities because outsiders, such as couriers, could access the storage lockers if they obtained a temporary authentication method. The present invention allows only those registered in the resident database (211), which is built based on occupancy contract information or household member registration information received from the management office server (600) of the apartment complex, to enter the warehouse (400), thereby fundamentally blocking the possibility of outsiders accessing it at the system design level. Unlike simple password-based authentication, this realizes a qualitatively superior security structure compared to conventional technology in that the apartment complex management administrative database and physical access control are linked in real time.

[0018] Second, it has the effect of reducing payment infrastructure costs and maximizing convenience of use. Conventional billing for the use of warehouses or storage lockers is carried out through on-site currency readers, separate card terminals, or independent payment applications, which entails separate hardware investment and maintenance costs. Since the present invention processes billing solely through data communication linkage with a management fee settlement system (300) already operated by a joint housing management office, additional payment terminal installation costs are unnecessary. Furthermore, residents can pay the warehouse usage fee through a familiar monthly management fee bill without any separate payment action, thereby significantly lowering the barrier to entry for use.

[0019] Third, there is a structural effect of resolving the risk of non-payment. Since warehouse usage fees are included in the management fee items, the existing sanctions structure for management fee arrears under the Multi-Family Housing Management Act—such as the imposition of late fees and legal measures—is automatically applied to non-payment of warehouse usage fees. This provides a powerful deterrent effect against non-payment that is difficult to achieve with independent private payment channels, thereby enhancing the profitability of the business operator. This effect does not originate from any single component, but is an unpredictable synergistic effect that is manifested only through the organic combination of the access control terminal (100), authentication management module (210), billing processing module (220), and management fee settlement system (300).

[0020] Fourth, there is an effect of improving the efficiency of integrated operation of the management office. The warehouse usage status, occupancy period per resident, and usage fee calculation details are managed uniformly within the management server (200) linked to the existing management office server (600), so there is no need to introduce separate settlement software or double accounting. Since the management fee bill generation unit (310) automatically generates an integrated bill including warehouse usage fees at the end of each month, manual intervention by management office staff is minimized.

[0021] Fifth, there is an effect of a complex billing structure that combines occupancy period, grade, and location. Conventional waste collection billing systems adopt a simple billing structure based on a single physical quantity (weight) on a one-time usage event basis. In contrast, the present invention provides a segmented fee system that responds to various collection demands by complexly operating period billing with continuous occupancy period as an independent variable, space billing with storage container volume grade as an independent variable, location billing with distance from households as an independent variable, and additional unit price billing for excess occupancy. This multi-variable complex billing structure is structurally distinct from single-variable billing prior art and creates a new degree of freedom in fee design that is unpredictable to those skilled in the art by simply combining known individual technologies.

[0022] Sixth, there is an effect of space efficiency and cost reduction for residents through shared rental. The shared rental mode (Claim 14), which allows short-term rental to other residents during the period when a resident is temporarily not using the warehouse and automatically deducts the corresponding profit from the management fee of the original occupant, has unique value in that it realizes a space sharing economy through a single channel of the management fee bill without requiring separate registration with a private warehouse sharing platform.

Specific details for implementing the invention

[0025] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. In describing the present invention, specific descriptions of related known functions or configurations are omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the present invention.

[0027] Referring to FIGS. 1 and 2, the billing-type warehouse management system for residents of a multi-unit dwelling according to the present invention comprises an access control terminal (100), a management server (200), a management fee settlement system (300), a warehouse (400), a resident terminal (500), and a management office server (600).

[0029] The access control terminal (100) is a hardware device installed at the entrance (420) of a warehouse (400) provided within a multi-unit housing complex or at the front of each individual storage box (410), and performs the function of receiving authentication information including building and unit number information or an access authentication key from a registered resident of the multi-unit housing complex. The access control terminal (100) is equipped with a plurality of authentication means including an RFID card reader (110), a password input pad (120), a biometric recognition sensor (130), and a wireless communication module (140). The RFID card reader (110) is configured to read an RFID card or key tag of the same specifications as those used for accessing the common entrance or elevator, so that a resident can reuse the existing common entrance card key for accessing the warehouse (400) without having to obtain a separate additional card. The password input pad (120) is implemented as a keypad or touchscreen equipped with number keys from 0 to 9, and authentication information is generated when a resident enters a password linked to a building and unit number that has been pre-registered with the management server (200). The biometric recognition sensor (130) can be implemented as a fingerprint recognition module or an iris recognition module and is activated when a resident registers biometric information with the management server (200). The wireless communication module (140) supports near-field wireless communication using NFC (Near Field Communication) or Bluetooth, so that when a resident touches or brings a smartphone with a dedicated mobile application installed near the terminal, the unique identification information of the smartphone is transmitted as authentication information. The access control terminal (100) can be configured by combining one or more of the above four authentication means, and preferably, the RFID card reader (110) and the password input pad (120) are configured as basic components, and the biometric recognition sensor (130) or the wireless communication module (140) can be optionally added depending on the security level.

[0031] The management server (200) is composed of software function blocks including an authentication management module (210) and a billing processing module (220), and is connected to a management office server (600) within the apartment complex via a network to synchronize data in real time.

[0033] The authentication management module (210) receives authentication information from the access control terminal (100) and compares the information with the resident database (211) to identify and authenticate in real time whether the user is a household member registered in the resident database (211) of the apartment complex. The resident database (211) is built based on occupancy contract information and household member registration information regularly received from the management office server (600), and is stored in a record structure including the building and unit number of each household, the name and biometric information of the registered resident (if consented to), an RFID card identification code, and a unique identification number of the registered smartphone. When authentication is completed, the authentication management module (210) sends an opening signal to the electronic lock of the warehouse (400) and records the resident identification code, the type of authentication method, and the time of authentication in the usage history record book (221). On the other hand, if an authentication attempt is made by a person not registered in the resident database (211), the authentication management module (210) immediately blocks access to the warehouse (400), records an unauthorized access attempt event (time of attempt, type of input authentication information, access control terminal identification number) in the management server (200), and simultaneously sends an alarm notification to the management office server (600). Through this, the history of security incidents, such as illegal intrusions disguised as delivery personnel, is automatically accumulated and managed.

[0035] The billing processing module (220) is subdivided into a usage history record (221), a usage fee calculation unit (222), and a settlement linkage unit (223). The usage history record (221) records in real time the time of entry and exit of the resident's warehouse (400), the time of start and end of occupancy of the individual locker (410), the grade information of the locker in use, and the installation location information, and the data is encrypted and stored in the storage device of the management server (200). The usage fee calculation unit (222) calculates the final usage fee for the corresponding month based on the data accumulated in the usage history record (221). The usage fee calculation unit (222) is automatically executed at the monthly closing time (default setting: midnight on the last day of each month) and transmits the usage fee calculated for each resident to the settlement linkage unit (223) along with the building and unit number code. The settlement linkage unit (223) transmits usage fee data to the management fee settlement system (300) through an API (Application Programming Interface) provided by the management fee settlement system (300) or a predefined message format. The transmitted data includes a household identification code (building and unit number), an item name (e.g., storage fee), a usage period (start date to end date), a usage fee amount, and a transmission timestamp. The management fee bill generation unit (310) of the management fee settlement system (300) automatically adds the received storage fee to the current month's management fee bill along with existing management fee items such as electricity and water charges, and sends it to the residents.

[0037] The management fee settlement system (300) is a management fee calculation, notification, and collection processing system currently operated by a joint housing management office or entrusted management company, and includes a management fee bill generation unit (310) that processes storage usage fee data received from the settlement linkage unit (223) of the present invention. The management fee bill generation unit (310) classifies the received storage usage fee into other usage fee items, adds it to the current month's management fee for each household, and sends it to the household in the form of a postal or electronic bill according to the existing bill sending routine. Since the storage usage fee is added to the management fee, even if the resident does not pay the storage usage fee separately, the management fee arrears processing procedure (imposition of late fees, demand for payment, legal action) under the Joint Housing Management Act is applied in the same way, thereby structurally suppressing the risk of non-payment.

[0039] A warehouse (400) is a storage space exclusively for residents installed by utilizing idle space within a multi-unit housing complex, and includes one or more individual storage boxes (410) and an entrance (420) for the entire warehouse (400). The individual storage boxes (410) are classified into small, medium, and large grades according to their internal volume, and a unit price corresponding to each grade is set on the management server (200). Small grade storage boxes (410) have an internal volume of less than 0.5㎥ and are suitable for storing small household items, medium grade storage boxes (410) have an internal volume of 0.5㎥ or more and are suitable for storing seasonal items or small home appliances, and large grade storage boxes (410) have an internal volume of 1.5㎥ or more and are intended for storing large items such as bicycles, strollers, and sports equipment. The warehouse (400) is a long-term storage space exclusively for residents, distinguished from an unmanned parcel locker primarily intended for the temporary storage of parcels and delivery items, and can be implemented in a plurality of embodiments described below depending on its physical installation location.

[0041] Referring to FIG. 6, in the first embodiment of the warehouse (400), the warehouse (400) is installed in the form of a partition wall, lightweight panel, or modular assembly booth in an idle space outside the parking space lines within the underground parking lot of a multi-unit building. When installed in an underground parking lot, the entrance (420) of the warehouse (400) is equipped with a separate access control terminal (100) that operates independently of the existing vehicle access barrier of the underground parking lot, thereby forming a double security structure so that even if a visitor with vehicle access authority enters the underground parking lot, they cannot enter the warehouse (400) area without resident authentication. Since the idle space of the underground parking lot is an area outside the parking space under the Building Act, it is often possible to install a partition wall without a separate change in the building permit, making this the most realistic embodiment for installing an additional warehouse (400) in an existing complex.

[0043] Referring to FIG. 7, in the second embodiment of the warehouse (400), the warehouse (400) is installed in the form of an independent container or a prefabricated modular structure in a common ground space within a multi-unit housing complex. An access control terminal (100) is embedded or attached to the outer wall of the container-type warehouse (400), so that only those who have completed resident authentication can enter the interior, even if it is located within the complex. The independent container structure has the advantage of being easy to move and expand, allowing for flexible response to seasonal changes in storage demand.

[0045] Referring to FIG. 8, in the third embodiment of the warehouse (400), the warehouse (400) is installed in a common space adjacent to the pilotis floor or the common corridor of each floor of a multi-unit building. In this embodiment, the entrance (420) of the warehouse (400) is directly connected to the common corridor of the floor or building, so that residents can access the warehouse (400) without moving from the floor or building where their household is located. The floor-to-floor proximity installation structure significantly improves the convenience of service use by minimizing the distance residents have to carry heavy items.

[0047] Referring to FIG. 9, in the fourth embodiment of the warehouse (400), the warehouse (400) is installed in a distributed manner at multiple locations within a multi-unit housing complex, and the usage fee calculation unit (222) additionally reflects a location grade calculated based on the distance or difference in floors between the installation location of the warehouse (400) used by the resident and the household of the resident in the usage fee calculation factor. Specifically, the usage fee calculation unit (222) classifies the warehouse (400) with a straight-line distance of 50m or less from the household as location grade 1, the distance exceeding 50m and within 100m as grade 2, and the distance exceeding 100m as grade 3, and calculates a usage fee with a 30% premium added to the standard unit price for the grade 1 warehouse (400), while calculates a usage fee with a 20% discount on the standard unit price for the grade 3 warehouse (400). Through this, a market mechanism is formed in which residents can choose between a high-convenience warehouse (400) close to their generation and a low-cost warehouse (400) far away, according to their budget and convenience.

[0049] Below, multiple embodiments regarding the specific billing calculation method of the usage fee calculation unit (222) are described.

[0051] Referring to FIGS. 4 and FIG. 10, in the first billing embodiment of the usage fee calculation unit (222), the usage fee calculation unit (222) records the time when a resident first opens an individual storage box (410) as the start time of occupancy and records the time when the return process for the storage box (410) is completed as the end time of occupancy, thereby calculating the continuous occupancy period from the start time of occupancy to the end time of occupancy in daily units. The usage fee calculation unit (222) determines the usage fee by multiplying the calculated occupancy period by a pre-set daily unit price, wherein the usage fee is calculated regardless of the number of individual entry and exits that occurred during the occupancy period. This is a structurally distinguished part in that, unlike the prior art for garbage collection billing which performs immediate billing based on weight on a one-time input event basis, the present invention adopts the concept of continuous occupancy of space as a core billing variable. For example, if resident A occupies a medium-grade storage locker (410) on March 5, 2025, and returns it on April 2, 2025, the occupancy period is 28 days, and if the daily unit price of the medium grade is set to 500 won, the usage fee is calculated as 14,000 won. This usage fee is transmitted to the April management fee settlement system (300) through the settlement linkage unit (223) and added to the April management fee bill.

[0053] Referring to FIG. 11, in the second billing embodiment of the usage fee calculation unit (222), the usage fee calculation unit (222) supports a monthly regular subscription rate plan and a daily pay-as-you-go rate plan, and calculates the usage fee by referencing the rate plan selection information stored in the usage history record unit (221) for the rate plan type selected in advance by the resident. For a resident who has selected the monthly regular subscription rate plan, a fixed monthly fee is calculated as the usage fee regardless of the actual number of days of occupancy in the corresponding month. For example, if the monthly fee for a medium-grade locker (410) is set to 12,000 won, the usage fee is calculated as 12,000 won even if the resident uses the locker (410) for only 10 days in the corresponding month. On the other hand, for a resident who has selected the daily pay-as-you-go rate plan, the usage fee is calculated in proportion to the actual number of days of use according to the method of the first billing embodiment. The usage fees calculated according to both rate plans are all transmitted to the management fee settlement system (300) through the settlement linkage unit (223) and added to the current month's management fee.

[0055] Referring to FIG. 10, in the third billing embodiment of the usage fee calculation unit (222), the usage fee calculation unit (222) determines the usage fee according to a two-dimensional composite calculation formula that combines the occupancy period and the storage box grade by referring to storage box grade information classified into small, medium, and large grades based on the internal volume of the individual storage box (410). Specifically, the formula for the usage fee = daily standard unit price × grade coefficient × number of days of occupancy is applied, and the grade coefficient for the small grade can be set to 1.0, the grade coefficient for the medium grade to 1.5, and the grade coefficient for the large grade to 2.5. For example, if the daily standard unit price is set to 400 won, the usage fee for a resident who occupies a large grade storage box (410) for 30 days is calculated as 400 won × 2.5 × 30 days = 30,000 won. Under the same conditions, the usage fee for a resident occupying a small-grade storage box (410) is calculated as 400 won × 1.0 × 30 days = 12,000 won, thereby creating a reasonable differential usage fee proportional to the volume of the storage box (410). In this way, a two-dimensional complex billing structure that simultaneously applies two independent variables, such as the occupancy period and the storage box grade, as billing calculation factors is structurally distinct from conventional waste collection billing systems that use only a single physical quantity as a billing standard, and is a unique fee design structure that is difficult for a person of the art to derive even by simply combining two prior art technologies.

[0057] Referring to FIG. 12, in the fourth billing embodiment of the usage fee calculation unit (222), if the resident's occupancy period exceeds a standard period (e.g., 90 days) pre-set in the management server (200), the usage fee calculation unit (222) calculates an additional usage fee by applying an excess unit price (e.g., 1.5 times the standard unit price) higher than the standard unit price for the excess period. Additionally, the usage fee calculation unit (222) automatically sends a return notification message to the resident terminal (500) a predetermined number of days (e.g., 7 days) before reaching the standard period, and records the sending history and excess billing calculation details in the management server (200) so that management staff can view them through the management office server (600). For example, if a resident occupies a medium-grade storage locker (410) for a total of 120 days by occupying it for a standard period of 90 days or more, the standard unit price (500 won / day) is applied for the 90 days within the standard period to calculate 45,000 won, and the excess unit price (750 won / day) is applied for the 30 days exceeding the standard period to add 22,500 won, so the total usage fee is calculated to be 67,500 won. This structure of adding excess unit prices functions as a means of operational efficiency that suppresses long-term exclusive occupancy of the storage locker (410) and promotes the cyclical use of the space.

[0059] Referring to FIG. 13, in the fifth billing embodiment of the usage fee calculation unit (222), the billing processing module (220) supports a shared rental mode that allows short-term rental to other residents during the period when a resident is not using the warehouse (400). When the shared rental mode is activated, the management server (200) registers the scheduled period of non-use and available rental space of the storage box (410) in a shared rental list exclusively for residents within the complex, and allows other residents to view the list and apply for a short-term rental. When a short-term rental is successful, the usage fee calculation unit (222) calculates the usage fee corresponding to the actual usage period of the short-term rental resident and adds it to the management fee for the unit number of the short-term rental resident, while transmitting the result of subtracting the short-term rental revenue from the usage fee of the original occupant for that period to the management fee settlement system (300) through the settlement linkage unit (223). For example, if a resident of Unit 301 in Building 101 registers a medium-grade storage locker (410) owned by the resident as unused for the month of August 2025 and a resident of Unit 502 in Building 102 rents it for the month of August, the monthly fee of 12,000 won for the medium grade is added to the August management fee of Unit 502 in Building 102 as a storage usage fee, and the corresponding 12,000 won (or the amount after deducting platform fees) is deducted from the storage usage fee of Unit 301 in Building 101 in August. This shared rental mode enables a space sharing economy among residents through a single channel of the management fee bill without the need to separately sign up for a private storage sharing platform.

[0061] Hereinafter, the overall flow of the billing-linked warehouse management method of the present invention is described with reference to FIGS. 3 and FIG. 5. An access control terminal (100) installed in a warehouse (400) receives authentication information from a resident, such as an RFID card, a password, biometric information, or a smartphone NFC signal, and transmits it to an authentication management module (210) of a management server (200). The authentication management module (210) compares the received authentication information with the resident database (211) to determine whether authentication is successful or unsuccessful. If authentication is successful, it sends an opening signal to an electronic locking device, allows entry into the warehouse (400), and records the start time of use in the usage history record (221). If authentication fails, it blocks entry and records an unauthorized access attempt. When a resident finishes using the locker (410) and locks the entrance (420) or completes the return process of the locker (410), the authentication management module (210) records the end time of use and completes the corresponding record in the usage history record (221). At midnight on the last day of each month, the usage fee calculation unit (222) is automatically executed to calculate the usage fee for each resident based on the accumulated usage history of the month, and the settlement linkage unit (223) composes the calculated usage fee into a data packet including a household identification code, item name, usage period, amount, and transmission timestamp, and transmits it to the management fee settlement system (300). The management fee bill generation unit (310) of the management fee settlement system (300) generates an integrated bill by adding the received storage usage fee to the current month's management fee and sends it to each household, and as exemplified in FIG. 14, the storage usage fee item is listed as a separate item on the bill.

Claims

Claim 1 A billing-linked warehouse management system for multi-unit housing, comprising: an access control terminal installed at the entrance or individual storage locker of the warehouse, which receives authentication information including building and unit number information or an access authentication key from a registered resident of the multi-unit housing; an authentication management module that receives the authentication information from the access control terminal, identifies and authenticates whether the user is a household member registered in the resident database of the multi-unit housing, and controls the opening of the warehouse or individual storage locker upon completion of authentication, while refusing opening for access requests from external visitors or unregistered non-residents; and a management server that includes a billing processing module that calculates a usage fee based on the warehouse usage history of an authenticated resident, transmits the calculated usage fee to the management fee settlement system of the multi-unit housing, and links the calculated fee to be added to the current month's management fee bill for the corresponding building and unit number for automatic billing, wherein the warehouse is a dedicated space provided for the long-term storage of a resident's personal belongings and is distinguished from an unmanned parcel locker primarily intended for the temporary storage of parcels or delivery items. Claim 2 A billing-linked warehouse management system for a multi-unit dwelling according to claim 1, wherein the authentication management module performs authentication by referring to a resident database built based on move-in contract information or household member registration information received from the management office server of the multi-unit dwelling, and blocks access to the warehouse for authentication attempts by persons not registered in the resident database and records an unauthorized access attempt event on the management server. Claim 3 A billing-linked warehouse management system for multi-unit housing according to claim 1, characterized in that the access control terminal physically and systematically guarantees exclusive access for residents by reusing the resident's existing access authentication key through at least one of an RFID card reader, a password input pad, a biometric recognition sensor, and a communication module that performs wireless communication with the user's smartphone, which is identical to the one used for accessing a common entrance or elevator. Claim 4 A billing-linked warehouse management system for multi-unit housing according to claim 1, wherein the billing processing module calculates the usage fee differentially based on at least one of the number of times the user enters and exits the warehouse, the time spent inside the warehouse, the period of occupancy of a specific individual storage locker, and the size of the space of the storage locker used. Claim 5 A method for managing a warehouse for a multi-unit dwelling, performed by a computing device, comprising: (a) obtaining building / unit number or access authentication key information from a user through an access control terminal installed in the warehouse; (b) performing authentication by comparing the obtained information with a pre-established resident database and authorizing access to the warehouse; (c) generating usage history data based on the user's warehouse usage start and end times or individual locker rental information; and (d) calculating a usage fee based on the usage history data and transmitting it to a management fee settlement server of the multi-unit dwelling to automatically include it in the management fee bill for the corresponding building / unit number. Claim 6 A billing-linked warehouse management system for a multi-unit dwelling according to claim 1, wherein the warehouse is partitioned and installed in the form of a partition wall, lightweight panel, or modular assembly booth in an idle space outside the parking space line within the underground parking lot of the multi-unit dwelling, and is equipped with an access control terminal independent of the existing vehicle access control system of the underground parking lot, so that entry into the warehouse area is blocked even within the underground parking lot without resident authentication. Claim 7 A billing-linked warehouse management system for multi-unit housing, characterized in that, in claim 1, the warehouse is installed in the form of an independent container or a prefabricated module structure in a common ground space within the multi-unit housing complex, and the access control terminal is embedded or attached to the outer wall of the structure so that only those who have completed the resident authentication can enter the interior even if located inside the complex. Claim 8 A billing-linked warehouse management system for multi-unit housing, characterized in that, in claim 1, the warehouse is installed in a common space adjacent to the pilotis floor or the common corridor of each floor of the multi-unit housing building, and the entrance of the warehouse is directly connected to the common corridor of the floor or building, so that a resident can access the warehouse without moving separately from the floor or building where their household is located. Claim 9 A billing-linked warehouse management system for multi-unit housing, wherein, in claim 1, the warehouse is distributed and installed at multiple locations within the multi-unit housing complex, and the billing processing module additionally reflects a location grade calculated based on the distance or difference in floor level between the installation location of the warehouse used by the resident and the household of the resident into the fee calculation factor, thereby calculating differentially such that a higher fee is charged for warehouses closer to the household. Claim 10 A billing-linked warehouse management system for multi-unit housing according to claim 1, wherein the billing processing module records the time when the resident first opens an individual storage locker as the start time of occupancy and records the time when the said storage locker is returned as the end time of occupancy, calculates the continuous occupancy period from the start time of occupancy to the end time of occupancy in daily units, determines the usage fee by multiplying the calculated occupancy period by a preset daily unit price, and wherein the usage fee is calculated regardless of the number of individual entries and exits that occurred during the occupancy period. Claim 11 A billing-linked warehouse management system for multi-unit housing, characterized in that, in Clause 10, the billing processing module calculates the usage fee by referring to the type of rate plan previously selected by the resident among a monthly regular subscription rate plan and a daily pay-as-you-go rate plan, wherein if the monthly regular subscription rate plan is selected, a fixed monthly fee is calculated regardless of the actual occupancy period of the corresponding month, and if the daily pay-as-you-go rate plan is selected, the usage fee is calculated in proportion to the number of actual days of use, and both rate plans are transmitted to the management fee settlement system and billed together with the management fee for the current month. Claim 12 A billing-linked warehouse management system for multi-unit housing, characterized in that, in claim 10, the billing processing module determines the usage fee according to a composite calculation formula combining the occupancy period and the storage grade by referring to storage grade information classified into small, medium, and large grades based on the internal volume of the individual storage unit, and calculates the usage fee so that it increases proportionally as the storage grade increases even for the same occupancy period, thereby configuring a two-dimensional billing structure in which the size of the usage space and the occupancy period are independent variables. Claim 13 A billing-linked warehouse management system for multi-unit housing according to claim 10, wherein the billing processing module calculates an additional usage fee by applying an excess unit price higher than the standard unit price to the excess period when the occupancy period of the resident exceeds a standard period pre-set on the management server, automatically sends a return notification to the resident's terminal a predetermined number of days before the occupancy period reaches the standard period, and records the notification sending history and excess billing calculation details on the management server so that the management office can view them. Claim 14 A billing-linked warehouse management system for multi-unit housing, characterized in that, in claim 1, the billing processing module supports a shared rental mode that allows short-term rental to other residents during the period when the resident does not use the warehouse or individual storage unit, and for the period during which the shared rental occurs during the occupancy period of the original occupant, the shared rental revenue is deducted from the original occupant's usage fee for settlement, and the deducted settlement result is transmitted to the management fee settlement system to be reflected in the current month's management fee for the corresponding building and unit number, thereby ensuring that the reduction in usage fees through space sharing among residents is processed through a single channel for the management fee bill.
