5 is a flowchart illustrating an operation of the digital door lock apparatus 100 according to an exemplary embodiment of the present invention.

The motion sensor 116 installed on the outdoor body 110 detects the movement of the door front object and generates a detection signal (S510). The motion sensor 116 transmits the generated detection signal to the controller 124 (S520).

The controller 124 photographs the front of the door by operating the camera module provided in the stationary smartphone according to the detection signal received from the motion sensor 116, and the captured image is transmitted through a wired / wireless communication module built in the stationary smartphone. The control signal is generated to be stored in the external storage (S530). The controller 124 transmits the control signal generated in step S530 to the mounted smartphone (S540).

The mounted smartphone photographs the front of the door with the built-in camera module as it receives a control signal from the controller 124 and stores the captured image in an external storage (S550).

The user may access the external storage through the electronic device and check the stored captured image. Accordingly, when an intruder occurs, the user may utilize the captured image like a CCTV image or remotely control the digital door lock device.

Another embodiment will be described with reference to FIG. 6. 6 is a flowchart illustrating an operation of a digital door lock apparatus according to another embodiment of the present invention. Specifically, the operation for the function of recognizing the visitor as a text message is shown. Operations of the mobile terminal (hereinafter, referred to as a mobile terminal) and the digital door lock apparatus 100 used by a user to be described below may be performed by an application mounted on the mobile terminal.

The visitor may transmit a text message to a mobile terminal (hereinafter, referred to as a mobile terminal) used by a user, rather than a smartphone mounted on the digital door lock apparatus 100 according to an exemplary embodiment of the present invention. When the mobile terminal receives a text message from the visitor (S610), the mobile terminal determines whether it is currently connected to the home network (S620).

As a result of the determination, when not connected to the home network, the mobile terminal may request to connect to the home network (S622). For example, a pop-up window may be displayed on the display module of the mobile terminal to allow a user to request a network connection.

On the contrary, if the mobile terminal is connected to the home network, the mobile terminal determines whether a preset character string is included in the received text message of the visitor (S630). The preset string is a string previously set by the user to identify the visitor, and the user may set a specific visitor corresponding to the specific string.

If it is determined that the visitor's message includes a preset character string, the smartphone mounted on the digital door lock device 100 operates the built-in camera module to photograph the front of the door, and externally captures the captured image through the built-in wired / wireless communication module. Store in the storage (S640).

The user may determine the locking / unlocking of the door by checking the captured image stored in the external storage through the mobile terminal. According to the user's decision, the mobile terminal may generate a lock command signal / unlock command signal and transmit the lock command signal to the smartphone mounted on the digital door lock device 100.

The mounted smartphone transmits the lock command signal / unlock command signal received from the mobile terminal to the controller 124 through the connection interface 114 (S660).

The control unit 124 controls the lock driving unit 122 according to the received signal to lock or open the door (S670).

In FIGS. 5 and 6, the processes are sequentially executed, but are not necessarily limited thereto. In other words, since the processes described in FIGS. 5 and 6 may be applied by changing or omitting or executing one or more processes in parallel, FIGS. 5 and 6 are not limited to the time series order.

The control method of the digital door lock apparatus according to the present embodiment described in FIG. 5 and FIG. 6 may be implemented in an application and recorded on a recording medium readable by an electronic device. The recording medium in which an application for implementing the control method of the digital door lock device according to the present embodiment is recorded and the electronic device can read includes all kinds of recording devices storing data that can be read by the computing system.

The above description is merely illustrative of the technical idea of the present embodiment, and those skilled in the art to which the present embodiment belongs may make various modifications and changes without departing from the essential characteristics of the present embodiment. Therefore, the present embodiments are not intended to limit the technical idea of the present embodiment but to describe the present invention, and the scope of the technical idea of the present embodiment is not limited by these embodiments. The scope of protection of the present embodiment should be interpreted by the following claims, and all technical ideas within the scope equivalent thereto should be construed as being included in the scope of the present embodiment.
