Description

Door opening and closing control device and system

Technical Field

The present invention relates to an access door opening/closing control apparatus and system, and more particularly, to an access door opening/closing control apparatus and system capable of eliminating psychological anxiety of store customers, particularly female users, by opening an access door only for users of the corresponding sex in a male toilet and a female toilet installed in a commercial building using QR Code (QR Code: quick Response Code) paper output from a two-dimensional Code dispenser installed in the commercial building.

Background

Washrooms which are installed in commercial buildings where shops such as shops and restaurants are located and operated for store managers, store staff and store customers are generally classified into male washrooms and female washrooms.

As shown in fig. 1a, the doorway 10 of such a commercial building is operated in an open state to facilitate use by store personnel, store customers, etc., or as shown in fig. 1b, a door lock 20 is provided at the doorway of the bathroom to allow only store personnel, store customers, etc., who know the password to use the bathroom.

In a toilet room in a commercial building provided with a door lock, a store clerk notifies a customer of a door lock code so that the customer can use the toilet room, wherein the door lock code is very loosely managed, for example, the code is recorded in a specific place in the store, and thus the door lock code is leaked to anyone, or the store clerk orally transmits the code to the store customer, etc., so that a male can easily know the door lock code of a female toilet room.

As described above, even if the door lock is opened as shown in fig. 1a or the door lock is installed as shown in fig. 1b, the possibility of the password being leaked is very high, so that a male is immersed in a female toilet for a period of time of the human being's rare, or crimes such as taking a female as a subject to crime or scattering an illegally photographed image by installing a candid camera or the like continue to increase, and thus the feeling of anxiety of a female using the female toilet in the commercial building is increasing. Recently, with the gradual miniaturization of a candid camera, a hiding technology is gradually developed, and the sense of uneasiness of a female using a female toilet is increasingly large.

If a candid camera is found in a female restroom, a surrounding closed-circuit television monitoring system (CCTV: closed Circuit Television) camera is used to identify a suspect and track and arrest, but this is simply a post-measure and is not sufficient to eliminate the discomfort of the female using the restroom.

Therefore, there is a growing need for a novel door opening and closing control device and control system that can control the opening and closing of the door based on the sex of the user who wants to access the restroom provided in the commercial building, thereby fundamentally preventing the male from accessing the female restroom, and enabling the female customer to use the female restroom in a more comfortable state.

Alternatively, the access door opening and closing control apparatus 100 according to the additional embodiment of the present invention may be provided to be coupled to a sliding device such as a rail and capable of sliding movement in the up-down direction, and may automatically adjust its height by sliding movement in the up-down direction according to the result thereof by sensing whether a user approaching the access door 300 is an adult or a child.

The access door opening/closing control apparatus 100 may be mechanically (hereinafter, refer to fig. 3 a) or wirelessly communicably (for example, bluetooth (hereinafter, refer to fig. 3b and 3 c)) connected to the access door 300, and in the latter case, a wireless communication module such as a Bluetooth chip may be further provided in the access door opening/closing control apparatus 100 in order to perform wireless communication with the access door 300.

In addition, according to an embodiment of the present invention, the QR code used by the access door opening/closing control apparatus 100 to control the opening/closing of the access door 300 is implemented by a QR code paper 240 (hereinafter, see fig. 3 and 4), and the QR code paper 240 may be output through the output modules 220 of the QR code dispenser 200 respectively installed in the store in the commercial building.

Accordingly, the access door opening/closing control apparatus 100 according to an embodiment of the present invention can scan the QR code output on the QR code paper 240 held by the user of the toilet and control the opening/closing of the access door 300 based on the read result thereof. For reference, a specific operation, procedure, etc. of opening or closing the access door 300 according to whether the QR code is authenticated or not will be described in more detail below.

In addition, as shown in fig. 2a, the access door opening and closing control apparatus 100 according to an embodiment of the present invention may be constructed using a host 110, a display 120, a QR code scanner 130, a controller 140, and the like. For reference, the

components

110, 120, 130, 140 of the access door opening and closing control apparatus 100 shown in fig. 2a are merely exemplary components for explaining the functions, operations, etc. of the access door opening and closing control apparatus 100 according to an embodiment of the present invention, and thus it is apparent that additional components (e.g., a power supply section, a communication section, an alarm section, a monitoring section, etc.) may be further provided.

The host 110 constitutes a main body of the access door opening and closing control apparatus 100 and may be adhered to at least a portion of the area of the access door 300 or adjacent to the access door 300. In addition, the host 110 may be made of metal or synthetic resin, and may be implemented such that the exposed surface has a predetermined color, as shown in fig. 2a, the shape of which may be rectangular, but is not limited thereto.

In addition, as shown in fig. 2a, a display 120, a QR code scanner 130, etc. may be embedded or implemented on an exposed surface of the host 110, and a controller 140 may be programmably embedded (e.g., embedded) inside the host 110, and a door driving motor (not shown) may be disposed at an inner space of the entrance/exit door wall or a toilet inner space.

The display 120 may be disposed at an upper region of the access door opening and closing control apparatus 100, and may display information regarding whether the access door 300 determined based on the QR code read from the controller 140 is opened, information regarding QR code identification failure, information regarding valid time timeout of the QR code, status information of the access door opening and closing control apparatus 100, a User Interface (UI) for door lock bluetooth setting, a UI for valid time setting of the QR code, and the like.

For example, according to the result of the controller 140 recognizing the QR code, information such as "permit access" and "reject access" may be displayed on the display 120, information such as "recognize failure" may be displayed on the display 120 in case of abnormality of the apparatus or inability to judge the sex, and information such as "exceed use time" may be displayed on the display 120 in case of exceeding the availability time of the QR code. In which information displayed through the display 120 may be displayed in korean, and in order to facilitate access to a foreigner's restroom user in a store in a commercial building according to an additional embodiment of the present invention, the information displayed through the display 120 may be provided in both korean and english.

Further, the display 120 may be implemented as a touch-sensitive display, whereby a building manager can easily control bluetooth communication settings with the access door 300, valid time settings of QR codes, etc. (e.g., 3 minutes, etc.) by touching the display 120.

In addition, according to the additional embodiment of the present invention, a variety of contents (for example, a building/store advertisement video, etc.) that are interesting to the user or provide information may be played on the display 120, and these contents may be stored in advance in a memory (not shown) further built in the access door opening/closing control device 100, and updated periodically, in addition to the time when the identification result of the QR code is displayed on the display 120.

For reference, the Display 120 may be implemented by a liquid crystal Display (LCD: liquid Crystal Display), a thin film transistor liquid crystal Display (TFT LCD: thin Film Transistor-Liquid Crystal Display), an Organic Light-Emitting Diode (OLED), a Flexible Display (Flexible Display), a three-dimensional Display (3D Display), or the like, but is not limited thereto.

The QR code scanner 130 may be configured to scan a QR code output on a QR code paper 240 held by a user who wants to use the toilet. The present invention is characterized in that the opening and closing of the entrance/exit door of the male restroom or the female restroom is controlled based on the QR code authentication, more specifically, the entrance/exit door 300 of the male restroom can be opened only when the male restroom is authenticated as male by the QR code authentication and the unique code is identical and the valid use time condition is satisfied, and the entrance/exit door 300 of the female restroom can be opened only when the female restroom is authenticated as female by the QR code authentication and the unique code is identical and the valid use time condition is satisfied.

Therefore, when a female customer visiting a store in a commercial building wants to use a female toilet in the commercial building, the female toilet in the commercial building can be used more easily and psychologically by acquiring the QR code paper 240 for female by a store clerk and simply scanning the acquired QR code paper onto the QR code scanner 130 provided in the access door opening/closing control apparatus 100.

For reference, the QR code issued by the QR code issuer 200 disposed at each store may include a plurality of codes, which may be composed of an inherent code, a sex code, and a date/time information code, for enhancing security and preventing malicious use, and a more specific structure of the QR code will be described in more detail in fig. 5 below.

The controller 140 may be programmably embedded (programmed) inside the host 110 of the access door opening/closing control apparatus 100, and may be implemented by a processor (processor), a microprocessor (micro-processor), a microcontroller (micro-controller), or the like, for example. The controller 140 generates an access door opening and closing control signal based on the read result of the QR code scanned by the QR code scanner 130, and controls the opening and closing of the access door 300 based on the generated access door opening and closing control signal.

More specifically, the controller 140 controls in the following manner: (i) The opening and closing of the door lock is controlled by a door driving motor electrically connected to the controller 140 and mechanically connected to the door 300 (for example, in the case of fig. 3 a), (ii) or by transmitting an access door opening and closing control signal to the door 300 by connecting to the door 300 implemented as the door lock using short-range wireless communication (for example, bluetooth) (for example, in the case of fig. 3b and 3 c).

The controller 140 recognizes information included in the QR code of the QR code paper 240 issued by the QR code issuer 200 and provided to the store customer, discriminates whether the QR code is a QR code including a unique code of the access door opening/closing control apparatus 100 related to the store, whether sex information included in the QR code is male or female, whether valid use time (for example, 3 minutes) is satisfied based on date/time information included in the QR code, and the like, and generates the discrimination result as an access door opening/closing control signal to control opening/closing of the access door 300.

For example, in each store in a commercial building, the available restroom may be specified restrictively, and the QR code issued by the QR code issuer 200 disposed in a specific store may include the unique code of the access door opening/closing control apparatus 100 provided in the restroom available for that store (for example, the restroom nearest to the store, or the restroom located on the same floor as the store, etc.). Therefore, when the result of detecting the unique code included in the QR code of the QR code paper 240 does not match the unique code of the access door opening/closing control apparatus 100 (for example, when another toilet is to be used instead of the one designated by the visiting store), the controller 140 generates the access door opening/closing control signal that does not allow the access door 300 to be opened.

Here, a series of operations including an operation of reading the scanned QR code, an operation of controlling the opening and closing of the access door 300 based on the result of the reading, and the like may be programmed as software and loaded in the controller 140, whereby the controller 140 may be implemented to automatically perform the step of controlling the opening and closing of the access door of the male restroom or the female restroom within the commercial building, and thus, there is no need to separately provide a management/operation server for remotely controlling and managing the access door opening and closing control apparatus 100, a smart phone application program for accessing the restroom, and the like, and thus, there is an advantage in that it can be more easily applied to restrooms of general commercial buildings.

In this regard, according to an additional embodiment of the present invention, the controller 140 may be further configured to generate an access door opening/closing control signal for allowing the access door 300 to be opened only once for the QR code.

More specifically, after the female user uses the QR-code paper 240 and uses the female toilet, if the QR-code paper 240 is not properly discarded, the male user may pick up the QR-code paper 240, causing a problem of malicious use for crimes. In order to prevent such a problem in advance, according to an additional embodiment of the present invention, in the case where the scanning has been completed and the QR code capable of causing the access door 300 to be opened is scanned again thereafter, even if all three conditions, that is, the condition of (i) the inherent code, (ii) the sex condition, and (iii) the effective use time are satisfied, the opening of the access door 300 may no longer be allowed for the QR code.

The QR code dispenser 200 may output a QR code paper 240 for use in a restroom within a commercial building. More specifically, as shown in fig. 2a, a QR code dispenser 200 according to an embodiment of the present invention may be constructed using a display 210 and an output module 220. For reference, in the present specification, the QR code dispenser 200 is implemented as a separate stand-alone device and is disposed in each store, but according to an additional embodiment of the present invention, by integrating the QR code dispenser 200 into a Point of sale (POS) device, the cost and space of the device for outputting the QR code paper 240 can be minimized.

In addition, the QR code dispenser 200 according to an embodiment of the present invention may be further provided with a locking function (e.g., password locking, etc.), and only authenticated users (i.e., store manager, store staff, etc.) can output the QR code paper 240 for use in a toilet through a predetermined authentication step. This can prevent, in advance, that a male customer unauthorized uses the QR code dispenser 200 to output and hold a female QR code paper and use the female QR code paper for crimes when the store staff is not present or when the store staff is concentrated on another business.

The QR code dispenser 200 according to an embodiment of the present invention may be respectively disposed in shops in a commercial building, and in case a customer visiting the shops wants to use a washroom, a shop clerk may output a QR code paper 240 printed with a QR code that can open the corresponding washroom access door 300 using the QR code dispenser 200 and provide the same to the customer.

At this time, an interface (for example, a touch type "man" icon or "woman" icon, hereinafter referred to as fig. 4) that can select the sex of the user of the toilet is provided through the display 210, and the shop staff member requests the issuance of the QR code paper 240 by touching the icon corresponding to the sex of the customer, and in response thereto, the QR code paper 240 including the sex code can be outputted through the output module 220 of the QR code dispenser 200.

In addition, a predetermined content (for example, a promotional video of the store) may be displayed in an area other than the sex selection icon on the display 210, and a memory (not shown) may be further provided in the QR code dispenser 200 in order to store such content. For reference, the display 210 may be implemented as a liquid crystal display, a thin film transistor liquid crystal display, an organic light emitting diode, a flexible display, a three-dimensional display, or the like, but is not limited thereto.

Therefore, a customer who obtains the QR-code paper 240 at a store clerk can easily and safely use the restroom in the commercial building by simply scanning the QR-code paper 240 to the QR-code scanner 130 disposed in the access door opening/closing control apparatus 100 for a specified restroom.

In connection with this, according to another embodiment of the present invention, the issued QR code may also be provided to the user terminal 400 of the customer instead of being output as paper from the QR code issuer 200, such a system being exemplarily shown in fig. 2 b.

As shown in fig. 2b, the QR code dispenser 200 of the access door opening and closing control system 1000 according to another embodiment of the present invention may include a transmission module 230 instead of the output module 220. Accordingly, if a store clerk receives a request for generating a QR code by touching an icon corresponding to the sex of a visiting customer among the sex selection icons displayed through the display 210, the QR code issuer 200 may issue a QR code and transmit the issued QR code to the user terminal 400 of the customer through the transmission module 230.

Accordingly, a customer who receives the QR code from the QR code dispenser 200 through the user terminal 400 can easily and safely use the restroom in the commercial building by simply scanning the QR code displayed on the user terminal 400 onto the QR code scanner 130 disposed in the access door opening/closing control apparatus 100 for designating the restroom.

For reference, in order to be able to transmit the issued QR code to the user terminal 400, an interface (e.g., a touch-type keypad, etc.) for inputting a customer phone number may be further provided on the display 210, the issued QR code may be transmitted to the user terminal 400 in the type of a social networking service (SNS: social Network Service) chat software or in the type of a short message service (SMS: short Message Service)/multimedia information service (MMS: multi-media Message Service) information, or a near field wireless communication technology (NFC: near Field Communication) communication device in linkage with the QR code issuer 200 provided in a mall may be further provided, and if the user brings his terminal device close to the NFC communication device, the QR code may be transmitted to the user's terminal device, but is not limited thereto.

For reference, the User terminal 400 may also be referred to as a subscriber unit, subscriber station, mobile terminal, remote station, remote terminal, mobile device, access terminal, wireless communication device, user agent, user device, or User Equipment (UE). An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (SIP: session initialization Protocol) phone, a wireless local loop (WLL: wireless Local Loop) station, a personal digital assistant (PDA: personal Digital Assistant), a handheld device having wireless connection capability, a computing device, or other processing device connected to a wireless modem.

Fig. 3a to 3c are conceptual views for explaining an embodiment of controlling the opening and closing of the access door 300 based on the QR code authentication or not according to an embodiment of the present invention. The user may obtain the QR code paper 240 for opening the restroom in the commercial building through the QR code dispenser 200 disposed at each of the shops in the commercial building, and may request the opening of the access door of the restroom by scanning out the QR code on the issued QR code paper 240 on the QR code scanner 130 of the access door opening/closing control apparatus 100 according to an embodiment of the present invention.

The controller 140 may read the scanned QR code according to the loaded software (program) and generate an access door opening/closing control signal based on the read QR code, as shown in fig. 3a (a), and may not allow the access door 300 to be opened in case of a QR code authentication failure, whereas, as shown in fig. 3a (b), the access door 300 may be allowed to be opened by activating the door driving motor in case of a QR code authentication success.

Alternatively, the controller 140 may read the scanned QR code according to software (program) loaded inside and generate an access door opening/closing control signal based on the read QR code, as shown in fig. 3b (a), and may not allow the access door 300 to be opened in the case where the QR code authentication fails, whereas, as shown in fig. 3b (b), in the case where the QR code authentication is successful, the access door 300 implemented in the manner of a door lock may be allowed to be opened based on bluetooth.

The case where QR code authentication fails has the following various cases. For example, the unique code included in the scanned QR code does not match the unique code of the access door opening/closing control apparatus 100, the sex information of the restroom in which the access door opening/closing control apparatus 100 is provided does not match the sex information of the QR code (for example, when the sex code of the QR code scanned by the QR code scanner 130 provided in the female restroom 100 is male), the valid use time of the QR code is exceeded, the QR code is a QR code that has been scanned.

Here, according to the result information of the reading of the QR code, the user may be displayed on the display 120, (i) when the identification information of the QR code matches the entrance/exit door opening condition, the user may display a statement such as "permit entrance/exit", when the identification information of the QR code does not match the entrance/exit door opening condition, the user may display a statement such as "reject entrance/exit", when the identification information of the QR code is not recognized, (iii) when the identification information of the QR code is not recognized, the user may display a statement such as "recognition failure", etc., on the display 120, (iv) when the identification information of the QR code exceeds the set use time, the user may display a statement such as "exceed the use time", etc., on the display 120, and (v) when the QR code is the QR code that has been scanned, the user may display 120.

That is, the controller 140 according to the present invention can generate the access door opening/closing control signal that allows the access door 300 to be opened only if all of the following conditions are satisfied, that is, (i) the unique code of the QR code matches the unique code of the access door opening/closing control apparatus 100, (ii) the sex code of the QR code matches the sex information of the access door opening/closing control apparatus 100, (iii) the QR code is scanned for the valid use time of the date/time information code of the QR code, and, as described above, the access door opening/closing control signal that allows the access door 300 to be opened only once is generated for each QR code.

As described above, in an embodiment in which the result of the QR code reading is visually displayed to the user as text, additionally or alternatively, according to another embodiment of the present invention, the access door opening/closing control apparatus 100 may be further provided with a speaker (not shown) and may express prompts such as "permit access", "reject access", "recognition failure", "beyond the usable time", "QR code used" in the form of voice through the speaker, or may also realize both text display through the display 120 and voice output through the speaker.

For reference, fig. 3a illustrates a structure in which the access door 300 is opened and closed by a sliding manner, and fig. 3b and 3c illustrate a structure in which the access door 300 is opened and closed by a switching manner, but this is merely for easy understanding of an example of the present invention, and thus it is apparent that embodiments according to the present invention may be applied to the access door 300 having any structure.

As described above, the access door opening/closing control apparatus 100 according to an embodiment of the present invention is capable of not only remarkably saving the cost for constructing a system, but also easily applying the access door opening/closing control service based on the QR code to most commercial buildings as long as the access door opening/closing control apparatus 100, the door lock, etc. disposed in a male or female restroom is newly built or replaced, since a series of operations including an operation of reading the scanned QR code, an operation of controlling the opening/closing of the access door 300 based on the read result, etc. are programmed as software and loaded in the controller 140, and thus a separate additional management/operation server is not required.

In the embodiments of fig. 3a and 3b, the structure of the access door opening and closing control device 100 is exemplarily shown to be provided and operated in the male and female washrooms, respectively, and according to an additional embodiment of the present invention, the single access door opening and closing control device 100 may also realize access door control for both the male and female washrooms, which is exemplarily shown in fig. 3 c.

As shown in fig. 3c, in an environment where a male restroom and a female restroom are disposed adjacent to each other, the access door opening and closing control device 100 may be disposed at a substantially middle position of the access door 300 of the male restroom and the access door 300 of the female restroom, and the access door opening and closing control device 100 and the two access doors 300 implemented as door locks may be simultaneously combined based on bluetooth communication.

For example, if a male user visiting a store in a commercial building receives a issued male QR code sheet 240 from an in-store QR code dispenser 200 and scans the QR code sheet 240 on a QR code scanner 130 of an access door opening/closing control apparatus 100 in order to use a restroom, the controller 140 determines that QR code authentication has failed for a female restroom whose sex codes are inconsistent, transmits an access door opening/closing control signal that does not open the access door 300, and at the same time (left side of fig. 3 c), determines that QR code authentication has succeeded if the sex codes are consistent, the unique codes are consistent, and the condition of valid use time is satisfied, and transmits an access door opening/closing control signal that opens the access door 300 to the male restroom (right side of fig. 3 c).

As described above, according to the additional embodiment of the present invention, by simultaneously controlling the male restroom and the female restroom adjacently disposed in the commercial building using the single access door opening/closing control device 100, it is possible to further save the cost for constructing the restroom access door opening/closing control service based on the QR code authentication.

For reference, in order to enhance security and prevent malicious use, a QR code according to an embodiment of the present invention may contain various code information, and the detailed structure of such a QR code 30 will be described in detail again in fig. 5 below.

Fig. 4 is a schematic diagram for explaining control of entrance and exit of a toilet based on QR code authentication using QR code paper according to an embodiment of the present invention.

First, a customer visiting a store within a commercial building may request use of a washroom from a store clerk, who responds thereto and issues a QR code paper 240 for use of the washroom thereto. For this reason, after judging the sex of the customer from the appearance, sound, or the like of the customer, the store clerk can output the QR code paper 240 through the output module 220 by clicking (or touching) an icon of the corresponding sex among the sex display icons displayed on the display 210 of the QR code dispenser 200.

Here, according to an additional embodiment of the present invention, an interface for inputting the valid use time of the QR code may be further provided on the display 210, and the store clerk may set the valid use time of the QR code at the time of outputting the QR code paper 240, and the QR code dispenser 200 may be implemented such that the set valid use time cannot exceed a predetermined maximum time (for example, 10 minutes).

As shown in fig. 4, assuming that a store customer is a female, a store clerk clicks a female icon on the display 210 to output a QR code sheet 240 for use in a female restroom and provide the same to the customer, and the customer who has received the QR code sheet 240 can easily and safely open the access door 300 and use the female restroom by scanning the QR code sheet 240 on the QR code scanner 130 provided in the access door opening/closing control apparatus 100 of the designated restroom.

If (i) the unique code of the QR code matches the unique code of the access door opening/closing control apparatus 100 (i.e., corresponds to a restroom designated by an visiting store), (ii) the sex code of the QR code is female (F), (iii) the scanning of the QR code is completed within the valid time (e.g., 3 minutes) of the date/time information code of the QR code, and (iv) the QR code is a new QR code that has never been used before, the controller 140 provided in the access door opening/closing control apparatus 100 for female generates and outputs an access door opening/closing control signal that allows the access door 300 to be opened, and opens the access door 300.

As shown in fig. 5, the QR code 30 of an embodiment of the present invention may be constituted of an inherent code 31, a sex code 32, and a date/time information code 33.

Among the plurality of codes included in the QR code 30, the unique code 31 may correspond to the unique code of the access door opening/closing control apparatus 100 disposed in the interior of the commercial building. In the case where a plurality of washrooms are provided in a commercial building, the unique codes assigned to the access door opening/closing control apparatuses 100 of the respective washrooms may be different from each other, and may be associated with, for example, the IP of the access door opening/closing control apparatus 100.

In general, the number of washrooms that can be used by staff or customers in a specific store is limited (for example, 1 for each of a male washroom and a female washroom), and for example, a designated washroom may be a washroom closest to the store, and by including the unique code 31 of the access door opening/closing control device 100 in the QR code 30, it is possible to effectively prevent customers visiting the store from using other washrooms than the designated washroom.

Further, among the plurality of codes included in the QR code 30, the sex code 32 may be a code indicating the sex of the user who obtained the QR code paper 240 (for example, male is "M" and female is "F"). Accordingly, the controller 140 does not have such a sex code in the QR code scanned by the QR code scanner 130, or even if the sex code is provided, if the sex does not coincide with the available sex of the restroom in which the access door opening and closing control apparatus 100 is provided, it may not be allowed to open the access door 300.

Further, among the plurality of codes included in the QR code 30, the date/time information code 33 may be used to recognize the usable valid time of the obtained QR code. For example, as shown in fig. 5, the QR code has "2020.08.01pm 2:34:56", so that it can be indicated that the QR code is 2:34 minutes 56 seconds.

For reference, in the case where the access door opening/closing control apparatus 100 does not have a communication function, the manager may adjust a time error between the access door opening/closing control apparatus 100 and the QR code dispenser 200, or further set a wireless fidelity (Wifi) communication function between the access door opening/closing control apparatus 100 and the QR code dispenser 200, pairing the two

apparatuses

100, 200 with each other, so that time can be synchronized, whereby inconvenience of a user caused by a time difference between the access door opening/closing control apparatus 100 disposed at the restroom and the QR code dispenser 200 disposed in the store can be prevented in advance.

The building manager can set the valid use time of the QR code by the display 120 of the access door opening/closing control apparatus 100, or when the QR code paper 240 is issued, the valid use time of the QR code (in this case, information on the valid use time may be further output on the output QR code paper 240) may be set by the issuer (for example, store clerks or the like), and it may be realized that the valid use time set in both cases cannot exceed a predetermined maximum time (for example, 10 minutes).

The controller 140 can perform control of opening and closing of the entrance/exit door of the washroom in the commercial building only when scanning is attempted within a preset effective time (for example, 3 minutes or the like) based on the issue date and time information of the QR code 30 included in the date/time information code 33.

Here, as shown in fig. 5, the QR code 30 according to an embodiment of the present invention includes only the sex information as the personal information, and thus can minimize the adverse sense of the user's provision and leakage of the personal information, and if the QR code output on the QR code paper 240 is encrypted on the QR code dispenser 200 and decoded by the software loaded on the access door opening/closing control apparatus 100, hacking or the like of the QR code can be prevented, whereby the QR code can be prevented from being stolen in an improper manner, and further the security can be enhanced.

As described above, according to the access door opening/closing control device and system according to an embodiment of the present invention, only the access door of the male restroom or the female restroom is opened/closed for the user of the corresponding sex by the QR code-based authentication method, so that the uncomfortable feeling of the store customer, particularly the female, who uses the restroom in the commercial building can be eliminated.

In addition, according to the access door opening and closing control apparatus and system of an embodiment of the present invention, the access door opening and closing control apparatus provided in a restroom in a commercial building is self-built in and runs software for controlling the opening and closing of the access door according to the reading of the QR code, so that an additional management/operation server is not required, thereby enabling to provide access door opening and closing control services to users in a more economical manner.

In addition, according to the access door opening and closing control apparatus and system of an embodiment of the present invention, the QR code paper for the entrance and exit authentication of the restroom is output by the QR code dispenser disposed at each of the shops in the commercial building, and the restroom is used by the shop customer by using the QR code paper, so that it is unnecessary to additionally use a separate application program and user terminal, and thus it can be more easily applied to the restroom in the commercial building.

Further, according to the access door opening and closing control device and system of an embodiment of the present invention, by including an inherent code of the access door opening and closing control device in the issued QR code or restricting the number of times the issued QR code is used within a valid time, it is possible to prevent the provided QR code from being misused by others or for other purposes.
