Description

Technology Field

[0001] The present invention relates to a water quality management system using QR codes. More specifically, it relates to a water quality management system using QR codes that can enhance user confidence in hygiene and effectively prevent safety accidents caused by water quality management failures by providing the user with water quality management history information of the relevant manufacturing device upon scanning a QR code. Furthermore, since it can be operated without the installation of separate auxiliary devices or dedicated apps, it is suitable for small-scale businesses or small franchise stores, thereby improving service interoperability and scalability, and increasing service convenience and efficiency. Background Technology

[0002] Recently, as the quality of life improves and taste preferences become more diverse, manufacturing devices capable of instantly producing water-based coffee, tea, beverages, and food, such as coffee machines, ice makers, and water purifiers, are becoming widely available, and in particular, the number of businesses selling food produced using these products to consumers is also increasing dramatically.

[0003] Since these manufacturing devices produce coffee, tea, beverages, and food based on water, hygiene management, such as water quality and filter maintenance, is essential.

[0004] In particular, since hygiene management in business establishments such as cafes is directly related to the health of consumers, water quality management of manufacturing equipment is required as an essential requirement.

[0005] Conventionally, business managers or rental managers of manufacturing equipment manage water quality by periodically replacing filters or cleaning them. However, this method has a structural limitation in that management history information is shared only with the managers in a limited manner, so consumers cannot receive unilateral and limited information, and consequently, it fails to increase consumers' confidence in hygiene.

[0006] FIG. 1 is a configuration diagram showing a smart coffee vending machine management system disclosed in Korean Patent Publication No. 10-2016-0149662 (Title of invention: IoT-based smart coffee vending machine management system and method).

[0007] The smart coffee vending machine management system of FIG. 1 (hereinafter referred to as the prior art) (100) comprises a user terminal (120) that receives a coffee mixing ratio from a user and transmits coffee production request information including the coffee mixing ratio to a coffee vending machine management device (130); a coffee vending machine (110) that produces coffee and provides it to the user by adjusting the mixing ratio of water, coffee, cream, and sugar according to a coffee production instruction control signal received from the coffee vending machine management device (130); and a coffee vending machine management device (130) that extracts the coffee mixing ratio from the coffee production request information received from the user terminal (120) and transmits a coffee production instruction control signal including the coffee mixing ratio to the coffee vending machine (110).

[0008] Additionally, when the coffee vending machine management device (130) receives a request to check hygiene status from the user terminal (120), it transmits a hygiene status check control signal to the coffee vending machine corresponding to the identification information included in the hygiene status check request, and the coffee vending machine (110) that receives the hygiene status check control signal transmits an image of the inside of the coffee vending machine taken using a camera installed inside or a measurement value of a color sensor installed inside to the coffee vending machine management device, and the coffee vending machine management device (130) provides a hygiene status grade according to the image or the measurement value of the color sensor to the user terminal (120).

[0009] In accordance with the user's request of the conventional technology (100) configured in this way, it has the advantage of increasing the user's confidence in hygiene by providing the user with hygiene information of the coffee vending machine.

[0010] However, the conventional technology (100) has structural limitations that make it practically impossible to apply to manufacturing devices such as coffee machines, ice makers, and water purifiers, as it requires not only to install a separate coffee app on the user terminal (120) but also to install a camera or sensor to detect hygiene conditions, which increases installation and operating costs.

[0011] In addition, the prior art (100) has the disadvantage of poor service accessibility because, in order for a user to check the hygiene status, the service can only be provided if a separate dedicated app (coffee app) is installed on the user terminal (120).

[0012] In addition, since the conventional technology (100) provides a limited information on the current hygiene status of the manufacturing device (coffee machine), a problem arises in that it cannot provide information on the water quality management history of the manufacturing device to the user. The problem to be solved

[0013] The present invention aims to solve these problems. The objective of the present invention is to provide a water quality management system using a QR code that can significantly increase the hygienic reliability of use and effectively prevent safety accidents caused by failure in water quality management, by enabling a user to access a web page displaying historical information on the water quality management of the manufacturing device simply by scanning a QR code attached to the manufacturing device.

[0014] Furthermore, another objective of the present invention is to provide a water quality management system using QR codes that is suitable for small-scale businesses or small franchise stores by enabling operation without the installation of separate auxiliary devices or dedicated apps, thereby improving service interoperability and scalability, reducing installation and operating costs, and enhancing service interoperability and scalability.

[0015] In addition, another objective of the present invention is to provide a water quality management system using QR codes that can enhance service convenience and efficiency by providing advertising information about nearby advertising merchants based on the number of connections (N) of a mobile terminal when a water quality management server connects via QR scan, thereby providing opportunities for merchants to generate revenue and increasing their voluntary participation, while simultaneously providing users with information about nearby merchants receiving water quality management. means of solving the problem

Specific details for implementing the invention

[0027] Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings.

[0028] FIG. 2 is a configuration diagram showing a water quality management system using a QR code, which is an embodiment of the present invention, and FIG. 3 is a conceptual diagram showing FIG. 2.

[0029] Figure 2 shows a water quality management system (1) using a QR code, which is an embodiment of the present invention. When a user scans a QR code, the system provides the user with water quality management history information of the manufacturing device, thereby increasing the user's confidence in hygiene and effectively preventing safety accidents caused by failure in water quality management. Additionally, since it can be operated without installing a separate auxiliary device or a dedicated app, it is suitable for small-scale or small franchise stores, thereby improving service interoperability and scalability, and increasing service convenience and efficiency.

[0030] In addition, the water quality management system (1) using QR codes according to the present invention is composed of QR codes (7-1), ..., (7-N) attached to each manufacturing device installed at each franchise store as shown in FIGS. 2 and 3, mobile terminals (5) that are terminals held by a user visiting the franchise store and support QR code scanning, a franchise terminal (9) that is a terminal of the franchise store, a manager terminal (8) that is a terminal held by a manager in charge of water quality management, a water quality management server (3) that operates water quality management services for each franchise store's manufacturing device, and a communication network (10) that provides a data transfer path between the water quality management server (3), the mobile terminal (5), the manager terminal (8), and the franchise terminal (9).

[0031] In this invention, for convenience of explanation, the QR code (7) is described as being installed (attached) to each manufacturing device, but the QR code (7) can be installed as a single unit at each affiliated store.

[0032] In addition, for convenience of explanation, the present invention is described as an example in which a franchisee requests a water quality management service for a specific manufacturing device from a water quality management server (3) through a franchisee terminal (9), and an administrator terminal (8) inputs water quality management result information and transmits it to the water quality management server (3); however, the input and transmission of water quality management result information may be performed at the franchisee terminal (9).

[0033] The communication network (10) supports data communication between the water quality management server (3), mobile terminal (5), manager terminal (8) and merchant terminal (9), and in detail, can be constructed as a wide area network (WAN), a local area network (LAN), a value added network (VAN), 3G / 4G / LTE / 5G, etc.

[0034] The merchant terminal (9) is a digital device that is placed in each merchant or is owned by the owner of each merchant, and in detail, it may consist of a smartphone, tablet PC, notebook, desktop PC, etc.

[0035] In addition, the merchant terminal (9) can access the homepage of the water quality management server (3) and request a water quality management service.

[0036] In addition, the merchant terminal (9) inputs personal information, membership information, merchant information (location, address, etc.), and manufacturing-device information (manufacturer, model, etc.) to be managed, and requests a water quality management service from the water quality management server (3).

[0037] At this time, when the water quality management server (3) receives a request for water quality management service from the merchant terminal (9), it registers the manufacturing device of the relevant merchant as a water quality management target, has a manager visit the relevant merchant, and then attaches a QR code (7) containing a website address (URL) that provides water quality management history information of the relevant manufacturing device.

[0038] The administrator terminal (8) is a digital device carried by an administrator who visits affiliated stores and manages the water quality of the manufacturing device according to the water quality management schedule information generated by the water quality management server (3), and in detail, it can be composed of a smartphone, tablet PC, notebook, etc.

[0039] Additionally, when the water quality management service of the manufacturing device is completed, the administrator terminal (8) transmits the water quality management result information to the water quality management server (3).

[0040] In this case, the water quality management result information includes franchisee identification information, manufacturing-equipment identification information, water quality management details, date, time, etc.

[0041] QR codes (7-1), ..., (7-N) are attached (installed) to each manufacturing device (11) of each franchise. In this invention, for convenience of explanation, the QR code (7) is described as being produced as a sticker and attached to a location adjacent to the manufacturing device (11), but the QR code (7) may be configured to be displayed on a separate display device.

[0042] For example, the QR code (7) can be attached in a location that does not interfere with the operation of the manufacturing device (11) and is clearly visible to the user (customer).

[0043] Additionally, the QR code (7) includes a homepage address (URL) provided by the water quality management server (3) and identification information of the corresponding manufacturing device.

[0044] This QR code (7) is scanned by the camera of the customer's mobile terminal (5), allowing the mobile terminal (5) to access the URL address provided by the water quality management server (3).

[0045] Figure 4 is a block diagram showing the mobile terminal of Figure 2.

[0046] As illustrated in FIG. 4, the mobile terminal (5) includes a control module (51) that manages and controls the operation of the mobile terminal (5), a communication module (52) that transmits and receives data to and from a water quality management server (3) connected to a communication network (10), a memory (53) in which data is stored, a camera (54) that scans a QR code (7), and an internet access program (55) that accesses a URL address detected by reading the QR code of the camera (54).

[0047] In this invention, for convenience of explanation, the means for scanning the QR code is described as a camera (54), but in detail, it is obvious that a processor is separately installed to read the QR code scanned by the camera (54) and access the URL address.

[0048] The internet access program (54) is a web browser that supports access to an internet homepage with a specific URL address, such as Chrome.

[0049] That is, when the mobile terminal (5) scans the QR code using the camera (54) according to the user's operation, the internet connection program (54) reads the QR code and connects to the homepage of the detected URL address. At this time, the homepage refers to a web page of the URL address provided by the water quality management server (3), and the water quality management server (3) provides a water quality management history interface to the mobile terminal (5) connected to the homepage, and the customer can view the water quality management history information of the corresponding manufacturing device through the water quality management history interface provided by the water quality management server (3).

[0050] Figure 5 is a block diagram showing the water quality management server of Figure 2.

[0051] As shown in FIG. 5, the parking lot management server (3) is composed of a control unit (30), a DB server (31), a data transmission and reception unit (32), a homepage management unit (33), a merchant registration unit (34), a water quality management result registration unit (35), a water quality management history information generation unit (36), a connection request data analysis unit (37), an advertisement-grade setting unit (38), an advertisement merchant extraction unit (39), and a history web-page generation unit (40).

[0052] The control unit (30) is the OS (Operating System) of the water quality management server (3) and manages and controls the operation of the control targets (31), (32), (33), (34), (35), (36), (37), (38), (39), (40).

[0053] Additionally, when the control unit (30) receives water quality management request data from the merchant terminal (9) through the data transmission and reception unit (32), it inputs the received water quality management request data into the merchant registration unit (34).

[0054] Additionally, when the control unit (30) receives water quality management result information from the administrator terminal (8) through the data transmission and reception unit (32), it inputs the received water quality management result information into the water quality management result registration unit (35).

[0055] Additionally, when the control unit (30) receives connection request data from the mobile terminal (5), it inputs the received connection request data into the connection request data analysis unit (37).

[0056] The DB server (31) stores franchise registration information registered by the franchise registration book (34). At this time, the franchise registration information includes personal information, membership registration information, franchise information (location, address, etc.), and manufacturing-device information subject to management (manufacturer, model, etc.).

[0057] In addition, the water quality management history information generated by the water quality management history information generation unit (36) is stored in the DB server (31).

[0058] In addition, the history web-page generated by the history web-page generation unit (40) is temporarily stored in the DB server (31).

[0059] Additionally, the DB server (31) stores connection-log data detected by the connection request data analysis unit (37). At this time, the connection-log data includes mobile terminal identification information, connection time, manufacturing device identification information, etc.

[0060] In addition, the DB server (31) stores a pre-configured standard table.

[0061] In this case, the reference table is data in which the ad grade (L) is matched according to the range of the user's connection count (N), and the ad grade (L) is set to a lower grade as the range of the connection count (N) is smaller, and to a higher grade as the range of the connection count (N) is larger.

[0062] In addition, the DB server (31) stores the previously configured second standard table.

[0063] In this case, the second reference table is data in which the quantity (N') of merchants to be advertised is matched according to the advertising grade (L); the lower the advertising grade (L), the smaller the advertising quantity (N'); the higher the advertising grade (L), the larger the quantity; and if the advertising grade (L) is the lowest, the advertising quantity (N') is set to '0'.

[0064] The data transmission and reception unit (32) transmits and receives data with the mobile terminal (5), the administrator terminal (8), and the merchant terminal (9).

[0065] When the homepage management unit (33) receives connection request data from the mobile terminal (5), it provides the 'history web page', which is a web page generated by the web page generation unit (40), to the connected mobile terminal (5).

[0066] Additionally, when a merchant terminal (9) requests a water quality management service, the website management department (33) provides a ‘registration web page’ to the merchant terminal (9) to receive personal information, membership information, merchant information (location, address, etc.), and information on the manufacturing device subject to management (manufacturer, model, etc.) from the user (merchant owner), and after generating water quality management request data including the information entered through the registration web page, inputs it into the merchant registration department (34).

[0067] FIG. 6 is an example diagram showing the first registration webpage of the registration webpage provided by the homepage management department of FIG. 5, FIG. 7 is an example diagram showing the second registration webpage of the registration webpage provided by the homepage management department of FIG. 5, and FIG. 8 is an example diagram showing the third registration webpage of the registration webpage provided by the homepage management department of FIG. 5.

[0068] For example, the homepage management department (33) can provide the first registration-webpage (911) of FIG. 6 when a request for water quality management is made from a merchant terminal (9).

[0069] At this time, the first registration webpage (911) displays a selection box (9111) that allows selecting the type of manufacturing device (11), and the homepage management unit (33) can provide the second registration webpage (912) of FIG. 7 when a specific type is selected by the user through the selection box (9111).

[0070] The second registration webpage (912) displays a second selection field (9121) for receiving selections from the user regarding capacity, size, etc., which can further subdivide the manufacturing device (11), and the homepage management department (33) can provide the third registration webpage (913) of FIG. 8 when a specific category is selected by the user through the second selection field (9121).

[0071] The third registration webpage (913) displays the contents of the water quality management service for the selected manufacturing device (11) in a schedule display section (9131) and a payment input section (9132) for receiving payment service input from the user due to service subscription.

[0072] At this time, for convenience of explanation, the 'registration-webpage (910)' of the homepage management section (33) of the present invention has been described as an example configured as shown in FIGS. 6 to 8, but the content, design, and configuration of such registration-webpage (910) are not limited to FIGS. 6 to 8, and it is obvious that various content, design, and configuration that can receive water quality management request data from a user can be applied.

[0073] The franchise registration department (34) generates franchise registration information by matching personal information, membership information, franchise information (location, address, etc.), and manufacturing device information (manufacturer, model, etc.) included in the water quality management request data entered from the website management department (33), and then stores this in the DB server (31) and simultaneously registers the franchise and manufacturing device as water quality management targets.

[0074] Additionally, when a water quality management target is registered in the merchant registration book (34), the schedule information for the water quality management service of the corresponding manufacturing device is generated and then stored in the DB server (31). At this time, the schedule information includes manufacturing device identification information, scheduled date and time for water quality management, water quality management details, and a manager to perform water quality management.

[0075] The water quality management result register (35) receives water quality management result information from the administrator terminal (8) under the control of the control unit (30), and determines that the water quality management of the corresponding franchise store and manufacturing device has been completed by referring to the entered water quality management result information.

[0076] The water quality management history information generation unit (36) receives water quality management result information from the administrator terminal (8) under the control of the control unit (30), processes and utilizes the received water quality management result information to generate water quality management history information, and then stores it in the DB server (31).

[0077] In this case, the water quality management history information includes franchisee identification information, manufacturing-equipment identification information, water quality management details, date, time, etc.

[0078] The connection request data analysis unit (37) is executed when receiving connection request data from the mobile terminal (5). At this time, when the mobile terminal (5) scans the QR code (7) and connects to the URL address, the connection request data is transmitted to the water quality management server (3).

[0079] Figure 9 is a block diagram showing the connection request data analysis unit of Figure 5.

[0080] The connection request data analysis unit (37) of Fig. 9 is executed when receiving connection request data from the mobile terminal (5), and analyzes the connection request data received from the mobile terminal (5).

[0081] In addition, the connection request data analysis unit (37) is composed of a connection request data input module (371), an identification information extraction module (372), a data search and reading module (373), a filtering module (374), a connection count (N) calculation module (375), and a connection log data generation module (376), as shown in FIG. 9.

[0082] The connection request data input module (371) receives connection request data received from the mobile terminal (5).

[0083] The identification information extraction module (372) extracts terminal identification information and manufacturing-device identification information included in the connection request data input through the connection request data input module (371).

[0084] The data search and reading module (373) searches for connection-log data stored in the DB server (31) and reads out connection-log data corresponding to terminal identification information extracted by the identification information extraction module (372).

[0085] The filtering module (374) selects, among the connection-log data of the corresponding terminal identification information read from the data search and reading module (373), 1) connection-log data stored for a preset period (T), and 2) among the selected connection-log data, finally selects the connection-log data having the manufacturing-device identification information extracted by the identification information extraction module (372).

[0086] The connection count (N) calculation module (375) calculates the connection count (N), which is the number of connection log data selected by the filtering module (374).

[0087] That is, the connection count (N) calculation module (375) calculates the connection count (N), which represents the number of times the user scans the QR code of the manufacturing device during the period (T).

[0088] The connection-log data generation module (376) generates connection-log data by matching the identification information, connection time, and manufacturing-device identification information of the mobile terminal (5).

[0089] At this time, the connection-log data generated by the connection-log data generation module (376) is stored in the DB server (31) under the control of the control unit (30).

[0090] The ad-grade setting unit (38) sets an ad-grade (L) corresponding to the number of connections (N) calculated by the connection request data analysis unit (37) by referring to a reference table stored in the DB server (31).

[0091] At this time, the reference table is data in which the ad grade (L) is matched according to the range of the number of connections (N), and the ad grade (L) is set to a lower grade as the range of the number of connections (N) is smaller, and to a higher grade as the range of the number of connections (N) is larger. For example, if the number of connections (N) of the user is 'first', the ad grade (L) of the reference table can be set to level 1, if the number of connections (N) of the user is '1 to 5 times', the ad grade (L) can be set to level 2, and if the number of connections (N) of the user is '6 times or more', the ad grade (L) can be set to level 3.

[0092] Generally, customers visiting a franchise store tend to visit frequently if they are satisfied with the store's food, coffee, tea, etc., and customers who are sensitive to water quality management tend to have a high level of interest in other franchise stores that provide the same water quality management services.

[0093] Considering these customer characteristics, the present invention provides advertisements for other franchise stores that are adjacent and provide the same water quality management service based on the number of visits (N) of customers visiting a franchise store that receives water quality management services. This not only provides opportunities for franchise stores to generate revenue but also induces voluntary participation from franchise stores and enables the provision of more diverse information to customers.

[0094] In addition, the advertising-grade (L) information set by the advertising-grade setting unit (38) is input into the advertising merchant extraction unit (39).

[0095] Figure 10 is a block diagram showing the advertising merchant extraction unit of Figure 5.

[0096] The advertising merchant extraction unit (39) of Fig. 10 is executed under the control of the control unit (30) when receiving advertising-grade (L) information from the advertising-grade setting unit (38).

[0097] In addition, the advertising merchant extraction unit (39) is composed of an advertising-grade (L) input module (391), an advertising merchant quantity (N') calculation module (392), a location comparison module (393), an advertising merchant determination module (394), and an advertising information generation module (395), as shown in FIG. 10.

[0098] The ad-grade (L) input module (391) receives ad-grade (L) information from the ad-grade setting unit (38).

[0099] The advertising merchant quantity (N') calculation module (392) refers to the second reference table stored in the DB server (31) and extracts the advertising merchant quantity (N') corresponding to the advertising grade (L) entered through the advertising grade (L) input module (391).

[0100] In this case, the second reference table is data in which the quantity (N') of merchants to be advertised is matched according to the advertising grade (L); the lower the advertising grade (L), the smaller the advertising quantity (N'); the higher the advertising grade (L), the larger the quantity; and if the advertising grade (L) is the lowest, the advertising quantity (N') is set to '0'.

[0101] The location comparison module (393) is executed when the number of advertising merchants (N') calculated by the advertising merchant quantity (N') calculation module (392) is one or more, and compares the location information of the merchant with the location information of the previously registered merchant to extract adjacent merchants.

[0102] The advertising merchant determination module (394) extracts merchants that are close in distance from adjacent merchants extracted through the location comparison module (393), based on the advertising merchant quantity (N') calculated by the advertising merchant quantity (N') calculation module (392), and then determines the extracted merchants as advertising merchants.

[0103] The advertising information generation module (395) generates advertising information including the location, industry, etc. of each advertising merchant by referring to the merchant registration information of the advertising merchants determined by the advertising merchant determination module (394).

[0104] The history web-page generation unit (40) provides a history web-page to the mobile terminal (5) that transmitted the connection request data.

[0105] At this time, the history web page displays the water quality management history information of the corresponding manufacturing device and the advertising information generated from the advertising franchise extraction unit (39).

[0106] For example, if there are no advertising merchants extracted from the advertising merchant extraction unit (39), the history web page may display only the water quality management history information of the corresponding manufacturing device, and if there are two advertising merchants extracted from the advertising merchant extraction unit (39), the history web page may display the water quality management history information of the corresponding manufacturing device and advertising information for the two advertising merchants.

[0107] In other words, the present invention provides advertising services to adjacent franchisees receiving the same water quality management service based on the number of times a customer frequently visits a specific franchisee, thereby enabling a win-win strategy for water quality management companies, franchisees, and customers, which can promote increased sales and increase the participation of franchisees.

[0108] As such, the water quality management system (1) using a QR code, which is an embodiment of the present invention, allows a user to access a web page displaying historical information regarding the water quality management of the manufacturing device simply by scanning a QR code attached to the manufacturing device, thereby significantly increasing the reliability of hygiene in use and effectively preventing safety accidents caused by failure in water quality management.

[0109] In addition, the water quality management system (1) using the QR code of the present invention can be operated without installing a separate auxiliary device or a dedicated app, making it suitable for small-scale businesses or small franchise stores, thereby improving service interoperability and scalability, reducing installation and operating costs, and increasing service interoperability and scalability.

[0110] In addition, the water quality management system (1) using a QR code, which is an embodiment of the present invention, provides advertising information about nearby advertising merchants according to the number of connections (N) of the mobile terminal when the water quality management server connects via QR scan, thereby providing an opportunity for merchants to generate revenue and increasing the voluntary participation of merchants, while simultaneously providing information about nearby merchants receiving water quality management to the user, thereby increasing service convenience and efficiency.
