The same reference numerals refer to the same components throughout the specification.

Unless otherwise defined, all terms (including technical and scientific terms) used in the present specification may be used as meanings commonly understood by those skilled in the art to which the present invention pertains. In addition, terms defined in the commonly used dictionary are not ideally or excessively interpreted unless specifically defined.

The terminology used herein is for describing the embodiments and is not intended to limit the present invention. In the present specification, the singular form also includes the plural form unless otherwise specified in the phrase. As used herein, “comprises” and/or “comprising” does not exclude the presence or addition of one or more other components other than the components mentioned.

In the present specification,'mobile terminal' or'user client' includes all of various devices capable of providing a result to a user by performing arithmetic processing. For example, the computer is not only a desktop PC and a notebook, but also a smart phone, a tablet PC, a cellular phone, and a personal communication service phone (PCS phone), synchronous/asynchronous.

Hereinafter, with reference to the drawings, an inaudible sound wave based door lock management server, door lock device, door opening and closing authentication method and application according to embodiments of the present invention will be described in detail.

1 is a block diagram of an inaudible sound wave based door lock management system according to an embodiment of the present invention.

2 is an internal configuration diagram of an inaudible sound wave based door lock management server according to an embodiment of the present invention.

1 and 2, an inaudible sound wave based door lock management server according to an embodiment of the present invention includes: an authentication key data receiving unit 110; Authentication performance unit 120; And opening and closing signal transmission unit 130; includes.

The authentication key data receiving unit 110 serves to receive authentication key data included in the inaudible sound wave signal transmitted from the first user client through a specific door lock device. The inaudible sound wave signal is generated and output at the opening and closing request point at the inaudible frequency by the first user client. The authentication key data includes at least one of an authentication code of a first user client, time data of the opening and closing request time, and a command key. The command key is key data that controls to lock or open the door lock.

The authentication code is used to distinguish a user client who wants to open or close the door lock. The authentication code includes phone number authentication information, SNS authentication information, or email authentication information. The phone number authentication information or the email authentication information is obtained or generated in a process in which a user performs authentication in an application.

For example, when the user's mobile terminal is opened, the application for door lock authentication performs a service provider authentication procedure through a phone number according to the user's selection or recognition of opening. Through this, the door lock authentication application uses the phone number itself or a code corresponding to the phone number as the authentication code. In addition, for example, if the user's mobile terminal is not opened (for example, when using Wi-Fi with an existing mobile phone without opening a phone when traveling abroad), the application for door lock authentication uses an email or SNS account. User authentication is performed through and the code corresponding to the email account or the SNS account is obtained according to the authentication result.

In addition, in another embodiment, the authentication code further includes application identification information. For example, the application identification information may be identification information provided for each application type. That is, when a number of services for authenticating a door lock based on a phone number have appeared, and an application is provided for each service, the application for authenticating the door lock authenticates the application identification information to convey to the door lock that the application is a service application capable of opening and closing a specific door lock. It can be included in code.

As another example, the application identification information is identification information given at the time of application installation. When the user changes the mobile terminal (that is, changes from the first mobile terminal to the second mobile terminal), the application identification information provided when the door lock application is installed on the first mobile terminal and the door lock application are newly installed on the second mobile terminal. According to the application identification information provided is different. Through this, as the new door lock application is installed in the new mobile terminal (ie, the second mobile terminal), application identification information given to the user is changed, so that the door lock can be opened and closed with the first mobile terminal where the door lock application was previously installed. It is possible to prevent the other person who has acquired the first mobile terminal (for example, the user has lost the first mobile terminal) from controlling the door lock opening and closing. When the user installs the application on another mobile terminal, the door lock management server may store and store new application identification information in accordance with the user information. The time data is used to determine whether the authentication key data is duplicated by another person. . The authentication procedure execution module 122, which will be described later, serves to distinguish the duplicated authentication key data using time data. That is, since the time data in the duplicated authentication key data differs by more than the current time and the error range, the authentication procedure execution module 122, which will be described later, determines whether the duplicated data is copied through the time data in the authentication key data.

The authentication execution unit 120 determines whether the door is opened or closed based on the authentication key data. The authentication execution unit 120 may determine whether to open or close the door lock device in various ways.

In one embodiment, the authentication unit 120, the authentication relationship storage module 121; And an authentication procedure execution module 122.

The authentication relationship storage module 121 serves to match the authentication codes of the specific door lock device 200 and the specific first user client 300 to store matching data. That is, the authentication relationship storage module 121 stores one or more first user clients 300 in which each door lock device 200 can be opened or closed.

The authentication relationship storage module 121 receives and stores matching data in various ways. For example, the authentication relationship storage module 121 may include an authentication code corresponding to the first user client from a second user client (for example, a phone number assigned to the mobile terminal corresponding to the first user client) and a specific door lock. The device receives identification information and stores matching data. The first user client and the second user client may be the same user client or different user clients.

When the second user client is a device distinguished from the first user client, the second user client requests to grant the first user client the opening and closing authority of one or more door lock devices. For example, the second user client may be a user client of a property owner who has a plurality of rooms. The second user client transmits an authentication code (for example, a phone number) of the first user client provided from a specific room and user desired by the user to the door lock management server to generate matching data for the door lock and the first user client. . Specifically, when a phone number is used as an authentication code, as the phone number is provided to the door lock management server and stored as matching data, the door lock management server may be notified through the phone number that the door lock opening/closing authority has been granted to the first user client. have. In addition, in the case of a first user without a phone number, the first user client is provided at the time of authentication through e-mail or SNS, and provides the code registered in the door lock application to the second user client (for example, the first user client Display the registration code corresponding to the email account or SNS account on the screen, or the first user client sends to the second user client through various wireless communication methods), and the second user client identifies the door lock device to the door lock management server The matching data is transmitted by transmitting the information. In addition, the second user client may be, for example, a client of a courier. As the courier delivers to the door lock management server, he/she obtains the authority to request the user's client's client to open and close the door lock. The second user client puts the specific first user's courier product into the storage space included in the specific door lock device, and inputs a telephone number corresponding to the first user client to identify and identify the door lock device (or a specific space in the door lock device). Match the phone number to store matching data. At this time, as the phone number is provided to the door lock management server and stored as matching data, the door lock management server has been granted the authority to open and close the door lock to the first user client through the phone number (ie, courier goods in the storage space of the door lock device). You can be guided.

In addition, for example, when a first user makes a reservation at an accommodation having multiple rooms, the first user uses an authentication code (for example, a phone number or an email account) on the web page through the first user client. Or the matching code in the SNS account), the door lock management server matches and stores the identification information of the room to be reserved and the authentication code. At this time, the door lock management server may store application identification information of the door lock application installed in the first user.

The authentication procedure execution module 122 serves to determine the opening and closing of a specific door lock device. First, the authentication procedure execution module 122 determines whether an authentication code (for example, a phone number) included in authentication key data and a door lock device providing authentication key data are included in the matching data. For example, the door lock management server determines whether the phone number included in the authentication key data is included in the matching data, and when the phone number is included in the matching data, the door lock device identification information corresponding to the phone number is the authentication key data. It is determined whether it matches the identification information of the door lock device that has transmitted the.

In addition, the authentication procedure execution module 122, if the authentication code includes an application identification code, performs a process of determining whether the authentication key data provided by the service application associated with the door lock. That is, the authentication procedure execution module 122 extracts application identification information included in the authentication key data and determines whether it is application identification information corresponding to the door lock service.

Thereafter, the authentication procedure execution module 122 determines whether the time data and the current time included in the authentication key data fall within an error range. The first user client acquires the authentication key data included in the inaudible sound wave signal itself or the inaudible sound wave signal generated at the first time point by another user client, and opens or closes the door lock at a second time point after the first time point. It is necessary to prevent the use. Therefore, the first user client includes the time data corresponding to the time point at which the request is generated in the authentication key data, and the authentication procedure execution module 122 compares the time data in the authentication key data with the current time. Through this, when the difference between the time data in the authentication key data and the current time point is greatly increased, it is possible to prevent the door lock opening and closing from being approved.

The opening/closing signal transmitting unit 130 serves to transmit an opening/closing signal to the door lock device. That is, the opening/closing signal transmission unit 130 transmits an opening/closing signal that is approved by the authentication key data received from the first user client and controls the door lock device to be opened or closed.

Play a role. That is, the door lock device 200 does not determine whether to open or close the door lock directly, and the authentication code (for example, a phone number) and time included in the authentication key data in the door lock management server 100 through the wireless communication unit 212. Result data determined by the data (that is, door opening/closing information) is received.

The control unit 213 serves to control the door opening and closing based on the door opening and closing information. That is, when the control unit 213 receives the result that the authentication code (for example, a phone number) and the door lock identification information included in the authentication key data from the door lock management server 100 correspond to a matching relationship stored in the matching data, The door may be opened or closed at the request of the first user client 300.

The wireless communication unit 222 receives one or more authentication codes (for example, phone numbers) approved for opening and closing the door lock from the door lock management server. That is, the door lock device 200 is an authentication code corresponding to a first user client that is granted control authority for a specific door lock device or a specific door in the door lock device from the door lock management server 100 to perform door control on its own (eg For example, a telephone number) is received. The wireless communication unit 222 may periodically receive an authentication code (eg, a phone number) of a user client having control authority, and a new user client may have control authority or an existing user client may control authority. If you are deprived, you can receive an authentication code (for example, a phone number) in real time. In addition, when there are a plurality of user clients capable of controlling a specific door lock device or a door in the door lock device, the door lock device 200 authenticates a plurality of user clients having control authority through the wireless communication unit 222 (for example, , Phone number) and store them internally. For example, when the door lock device 200 is a device having a plurality of article storage spaces and has doors that can be opened and closed for each article storage space, the door lock apparatus 200 can control the doors of each article storage space. The authentication codes (eg, phone numbers) of one or more user clients having authority are received and stored through the wireless communication unit 222. That is, the door lock device 200 matches and stores the authentication codes (eg, phone numbers) of each door and one or more user clients having control authority for the doors.

In addition, the wireless communication unit 222 may receive application identification information corresponding to the authentication code while receiving information on a specific door lock device or a door in the door lock device and one or more authentication codes corresponding thereto from the door lock management server. When the mobile terminal is changed while the phone number is maintained through the application identification information, the door lock device 200 prevents another person from controlling a specific door lock device or a specific door through the door lock application installed in the existing mobile terminal.
