The door lock device 100 may refer to a door locking device installed to distinguish one space from another space. In addition, the door lock device 100 described in detail herein may be widely used for access control means in a special facility such as a safe, an office, a guest room, a research institute, as well as a general home door.

The unique number information of the door lock device 100 is one of unique information for distinguishing the door lock device 100 from the other door lock device 100, such as a manufacturing number, serial number, ID assigned to the door lock device 100 Can be. By using the unique number information, the server 300 may manage the plurality of door lock apparatus 100 without confusion about requests and information about the plurality of door lock apparatus 100.

The opening time information and / or the opening frequency information may be used to confirm the validity of the sound wave signal output from the user terminal 200. In particular, when the place where the door lock device 100 is installed is a place where temporary visitors such as lodging facilities or offices are frequently accessed, the temporary visitor is allowed to access the temporary visitor only for a predetermined time unlike the administrator, so that the door lock device is opened by the temporary visitor in addition to the allowed time. 100 can be prevented from opening. In addition, even if it is necessary to open the door lock device only for a limited number of temporary visitors, the administrator can control the number of visits of the temporary visitors.

The sound wave signal may include opening control data of the door lock device 100, and the opening control data includes unique information and opening information. The unique information includes at least one of unique number information of the door lock device 100, code information corresponding thereto or based thereon, random number information, and OTP information, and the opening information includes at least one of opening time information and opening frequency information.

The server 300 may generate a sound wave signal by processing the source data by rearranging bits included in the source data according to a shuffle array used as a security code. The shuffle array may be stored in the server 300 and may be changed using date time information.

The sound wave signal may be generated for various frequency bands.

In one example, server 300 may generate a sound wave signal having a frequency band of 17.4 kHz to 19.8 kHz.

Bits included in the source data may have corresponding frequency posts. The minimum frequency spacing between the frequency posts may be set differently or uniformly for each sound wave signal generated. In addition, the source data may further include a CRC code. By maintaining a minimum frequency interval or by including a CRC code in the source data, it is possible to provide a sound wave communication method that is robust to external noise.

The server 300 may set a predetermined sound wave protocol to the generated sound wave signal. In one example, the sound wave protocol may include a sequence number and a payload.

The server 300 stores the generated sound wave signals on the web. The URL address at which the sound wave signal is to be stored may be determined using at least one of unique number information of the door lock device 100, time, and unique information of a user using the user terminal 200.

In one example, when determining the URL address using time, the Uniform Resource Locator (URL) address where the sound wave signal is to be stored is set to "http://www.000000.co using the date when the user transmits the sound wave signal request. .kr / guest20180109 ".

Embodiment of Providing Acoustic Wave Signal According to Request of Temporary Visitor

In one embodiment, after receiving the URL address information request from the user terminal 200, the server 300 generates and stores the sound wave signal, the URL address information stored in the sound wave signal to the user terminal 200 Can be configured to transmit.

By transmitting the URL address information only to the user terminal 200 that has transmitted the URL address information request as described above, it is possible to reduce the use of communication resources used for transmitting and receiving URL address information.

<Example in which the administrator provides a sound wave signal for the convenience of the temporary visitor>

In another embodiment, the server 300 receives the URL address information request from the terminal connected through the administrator account, generates and stores the sound wave signal, and stores the URL address information in which the sound wave signal is stored. 200).

Administrator account means an account used by an administrator (or a main user). Whether to allow access to the temporary visitor, an access allowance time (or duration), etc. may be determined according to predetermined information. As such, when controlling the sound wave signal to be directly provided to the temporary visitor through the manager, the temporary visitor who is not familiar with the control method of the door lock device 100 using the sound wave signal may be induced to easily use the control method.

In one embodiment, the URL address information request may include user specific information, and the server 300 generates and stores URL address information only when there is information corresponding to the user unique information, and the URL. The address information may be configured to be transmitted to the user terminal 200.

The user unique information may identify the user with other users such as fingerprint information, ID / password information, social security number, unique information of the user terminal 200, unique service code or service company information corresponding to the service being used by the user. It can be one of a variety of information that can be.

As such, the unique user information is included in the URL address information request, and the server 300 may determine to which user terminal 200 the URL address information is transmitted.

In another embodiment, the door lock device 100 may open the door lock device 100 only to a person (for example, a security company) who is allowed to enter by using user unique information.

When the door lock device 100 includes user specific information in the decoding result information of the sound wave signal, the user terminal 200 which transmits the user unique information to the server 300 and transmits the sound wave signal is allowed to enter (ie, Determine whether the terminal is authorized, and determine whether the current time is a time (or access within a threshold number of times) allowed to the user terminal 200 by referring to the opening time information. The door lock device 100 may be controlled to open only for a predetermined time.

In one example, the configuration allows the administrator to control only the security staff can open the door lock device 100 during the weekend.

The URL address information request may be transmitted and received through at least one of a text message, a web, a social network service (SNS) application, and a chatbot. The text message may be any one of a short message (SMS), a long message (LMS), and a multimedia message (MMS). The web is a means of delivering information on the Internet based on URL address information.

As such, when using a text message or the web, in addition to a tablet PC or a smartphone that can install an SNS application, a user who uses a feature phone that does not have an SNS application installed on the server 300 may use the feature phone. ) Can send a URL address information request. Therefore, the feature phone user can also use the door lock providing method of the present invention.

In addition, using the SNS application, the door lock providing method of the present invention can be used even in an environment where text message communication is not possible if only an Internet connection is possible.

Subsequently, referring to FIG. 1, the server 300 transmits URL address information in which a sound wave signal is stored to the user terminal 200 (S110).

2A illustrates that the server 300 transmits URL address information to the user terminal 200.

Referring to FIG. 2A, the door lock device 100 may be mounted on a surface of the both sides of the door facing the inner space. In the case of a button door lock device currently used, there is a possibility that unauthorized persons physically damage the door lock device. When opening and closing the door lock device using a sound wave signal, the door lock device is not exposed to the outside space of the door to prevent the possibility of physical damage and brutal force attack on the door lock device. can do.

2A illustrates the server 300, the user terminal 200, and the door lock device 100. The user terminal 200 is one of various devices capable of using at least one of the Internet, an SNS application, or a text message such as a PDA, a smart phone, a tablet PC, a feature phone, a notebook, a smart watch, and smart goggles. The server 300, the user terminal 200, and the door lock device 100 may transmit and receive information through the wireless Internet.

As such, when the user terminal 200 receives URL address information instead of the sound wave signal from the server 300, the URL address information has a smaller capacity than the sound wave signal, so that the user terminal 200 has insufficient wireless communication infrastructure. Alternatively, even when located in an area where communication signals are difficult to transmit, URL address information may be easily received from the server 300.

Referring to FIG. 2A together with FIG. 1, the server 300 may transmit URL address information “http://www.000000.co.kr/guest20180109” to the user terminal 200. The URL address information may be generated using visit date and time information of the user. For example, the URL address information to be issued to a visitor on January 09, 2018 may be generated as guest20180109 as described above. As shown in FIG. 2A, the user terminal 200 may output URL address information received from the server 300 visually (or audio).

As such, by outputting the received URL address information, the user terminal 200 may intuitively grasp that the URL address information is received from the server 300 as a feedback for the URL address information request.

The URL address information may be transmitted and received through at least one method of a text message, the web, an SNS application, and a chatbot. The text message may be any one of a short message (SMS), a long message (LMS), and a multimedia message (MMS). The web is a means of delivering information on the Internet based on URL address information.

As such, when using a text message or the web, a user using a feature phone in addition to a tablet PC or a smartphone that can install an SNS application may transmit a URL address information request to the server 300. Therefore, the feature phone user can also use the door lock providing method of the present invention.

In addition, if the URL address information is transmitted using the SNS application, the user may have limited access to the text message or the terminal having the terminal without the text message transmission function may use the door lock providing method of the present invention if only the Internet connection is possible. .

Referring back to Figure 1, the user terminal 200 outputs a sound wave signal with reference to the URL address information (S120).

That is, the user terminal 200 does not receive and reproduce the sound wave signal from the server 300, but receives only the URL address information in which the sound wave signal is stored from the server 300, and outputs the sound wave signal stored in the URL address information.

2B illustrates that the user terminal 200 outputs a sound wave signal.

Referring to FIG. 2B together with FIG. 1, the server 300 may output sound wave signals stored in the URL address information with reference to the URL address information “http://www.000000.co.kr/guest20180109”. . That is, the server 300 may output the sound wave signal by accessing the URL according to the URL address information and reproducing the sound wave signal stored in the URL address information.

As such, when the sound wave signal is output with reference to the URL address information, the sound wave signal for performing the door lock control method may be output without receiving a sound wave signal having a relatively large capacity from the server 300 from the URL address information. have.

There may be a case where a plurality of temporary visitors need to enter and exit the area where the door lock device 100 is installed.

In this case, the server 300 may generate different sound wave signals to be transmitted to the plurality of user terminals. Since the plurality of temporary visitors may have different time allowed to access the area in which the door lock device 100 is installed, each temporary visitor transmits different sound wave signals to a user terminal carried by different temporary visitors. You can control access only for the allowed time.

In addition, the server 300 may generate the same sound wave signals to be transmitted to the plurality of user terminals, and may store each sound wave signal to be transmitted to the plurality of user terminals at different URL addresses. With such a configuration, even if the sound wave signals are not generated differently for all the temporary visitors, a plurality of temporary visitors can be controlled according to time.

Referring to FIG. 1, the door lock device 100 receives a sound wave signal from the user terminal 200 (S130).

The present invention controls the door lock device 100 using sound wave communication. In particular, the present invention relates to unidirectional communication, with directionality, directed from a first terminal to a second terminal, among acoustic wave communications. When the bidirectional communication method is used for the control method of the door lock device 100, the door lock device 100 should be provided with both a microphone and a speaker to output and receive the sound wave signal. Since the door lock control method of the present invention uses a one-way communication method, the microphone is provided in the door lock device 100, but the speaker does not need to be provided. Therefore, the door lock device 100 can be produced at a lower manufacturing cost compared to the bidirectional sound wave communication method.

In one embodiment, the sound wave signal may not include user specific information.

In another embodiment, the sound wave signal may further include user specific information. An embodiment of a sound wave signal further including user specific information will be described in detail with step S140 below.

Referring to FIG. 1, the door lock device 100 decodes a sound wave signal (S140).

Subsequently, referring to FIG. 1, the door lock apparatus 100 generates authentication result data for the user terminal 200 based on the decoding result information (S150).

Specifically, the door lock device 100 corresponds to the unique number information included in the decoded sound wave signal corresponds to the unique number information of the door lock device 100 (or at least one of code information, random number information, and OTP information corresponding thereto). The authentication result data for the user terminal 200 may be generated based on whether the current time belongs to the opening time according to the opening time information.

In one example, the unique number information included in the sound wave signal may be "TCK824", and the opening time information may be "2018/01/30, 3:00 pm-8:00pm".

At this time, when the unique number information of the door lock device 100 receiving the sound wave signal from the user terminal 200 is "TCK824" and the current time is 4:30 pm, the unique number information and the sound wave signal of the door lock device 100 Since the unique number information included in the corresponding, and the current time belongs to the time interval according to the open time information, the door lock device 100 to generate authentication result data including information that the authentication for the user terminal 200 was successful. Can be.

At this time, when the unique number information of the door lock device 100 that receives the sound wave signal from the user terminal 200 is "ATECH82", the door lock device 100 does not correspond to the unique number information included in the sound wave signal. Authentication result data including information indicating that authentication for 200 has failed may be generated. That is, when the unique number information of the door lock device 100 does not correspond to the unique number information included in the sound wave signal, regardless of whether the current time belongs to the opening time according to the opening time information (that is, without determining ) May generate authentication result data including information indicating that authentication of the user terminal 200 has failed. In addition, the door lock device 100 may first determine whether the current time belongs to the opening time before determining whether the unique number information corresponds.

At this time, when the unique number information of the door lock device 100 receiving the sound wave signal from the user terminal 200 is "TCK824" and the current time is 9:00 pm, the current time is based on the open time information included in the sound wave signal. Since it does not belong to the opening time according to the door lock device 100 may generate authentication result data including information that the authentication for the user terminal 200 has failed. That is, the door lock device 100 may generate authentication result data including information indicating that authentication for the user terminal 200 is successful only when both requirements such as unique number information and opening time information are satisfied.

<Embodiment of the door lock device 100 operating on the off-line basis>

The sound wave signal may further include user specific information. In this case, the door lock apparatus 100 may record the authentication result data in association with the user specific information. The user unique information may distinguish the user from other users such as fingerprint information, iris information, phone number information, ID / password information, social security number, unique information of the user terminal 200 (eg, serial number, etc.). May be one of a variety of information.

As such, by recording the authentication result data in association with the user's unique information, the administrator can easily grasp the access record of the temporary visitor who is allowed to visit and the access attempt of an unauthorized person.

<Embodiment of door lock device 100 operating on-line basis>

The sound wave signal may further include user specific information. The user specific information is received by the server 300 from the user terminal 200. As such, the door lock apparatus 100 may transmit the decoding result information of the sound wave signal to the server 300 to allow the server 300 to generate authentication result data.

2c shows a door lock device 100 operating on an on-line basis.

In this case, the server 300 may store user unique information included in the URL address information request received from the user terminal 200. When the decoding result information is received from the door lock device 100, the server 300 determines whether the authentication of the user terminal 200 is successful or failed by comparing the stored user unique information with the user unique information included in the decoding result information. In addition, authentication result data including information on success / failure may be generated.

When the server 300 transmits the URL address information to the user terminal 200 without receiving the URL address information request from the user terminal 200, the server 300 does not have user unique information that is held, so that the door lock device 100 may be used. After receiving the decoding result information from the), it may transmit a user specific information request to the user terminal 200. When the user unique information is received from the user terminal 200, the server 300 compares the user unique information with the user unique information included in the decoding result information to determine whether the authentication of the user terminal 200 is successful or failed. In addition, authentication result data including information on success / failure may be generated.

In this way, the server 300 to perform the authentication result data generation for the user terminal 200, the door lock device 100 does not need to store a plurality of user-specific information, so that the recording medium included in the door lock device 100 Even if the storage space is small, it is possible to provide a door lock control method for a plurality of temporary visitors, and reduce the computational load on the door lock device 100.

Referring to Figure 1, the door lock device 100 controls the opening and closing portion of the door lock device 100 in accordance with the authentication result (S160).

2d shows the door lock device 100 in an open state.

Referring to FIG. 2D together with FIG. 1, when the authentication result data for the user terminal 200 includes information of “success,” the door lock device 100 controls the opening and closing unit of the door lock device 100. The door in which the door lock device 100 is installed may be opened. When the door is opened, the door lock apparatus 100 may transmit information related to which user terminal the door has been opened to the terminal or server 300 connected with a predetermined account. Through the above configuration, the administrator can easily grasp whether the temporary visitor succeeded in entering and exiting safely, and the server 300 may record an entry history of the temporary visitor.

On the other hand, if the authentication result data for the user terminal 200 includes the information "failure (failure"), the door lock device 100 by controlling the opening and closing of the door lock device 100 door door device 100 is installed May not open. In this case, the door lock apparatus 100 may visually or audibly output a message indicating a reauthentication request, or allow the server 300 to transmit a reauthentication request (or a new sound wave signal) to the user terminal 200. The signal may be transmitted to the server 300.

As such, by transmitting a new sound wave signal to the user terminal 200 after the authentication failure, the temporary visitor may enter and exit through the new sound wave signal even if the visitor is delayed due to some reason. You can adjust it to
