In addition, the smart door lock 100, which has received a message that is impossible to enter the household, displays it through the display unit 112. In this way, a person inside the household can determine whether or not the visitor enters, and the safety of the visitor is secured by not unlocking the door regardless of who the visitor is. This function is for safety by preventing unlocking of the door lock when there are only children or women in the household or as a single-person household. Here, the display unit 112 may display a message that is impossible to enter the household using a liquid crystal display, and it is possible to light a red light using a light emitting diode to inform the door not to be unlocked. For example, a message such as "Do not open the door" may be used as an example of a message that cannot enter the household. If the child does not know the writing, by educating the door not to open when the red light is lit through the display unit 112 in advance, it is possible to easily inform the indoor person of the door locking maintenance according to the visitor even if the writing is not known.

On the other hand, as another feature of the present invention, in the abnormal situation of destroying or damaging the smart door lock 100 from the outside, it is possible to notify the user in real time to prevent secondary damage.

For example, when an intruder damages the smart door lock 100 from the outside, the state detection unit 113 detects it in real time, and transmits abnormal state detection information to the main control unit 106.

The main control unit 106 performs an emergency alarm function when abnormal state detection information occurs, and transmits the emergency alarm information to the smartphone 200 through the security server 300 through the wireless communication module 109.

Here, when the emergency alarm function is executed, the main control unit 106 controls the camera 102 to shoot and store an external intruder and transmit it to the smartphone 200 at the same time. This function can be used to recognize and arrest intruders in the future.

In addition, the main control unit 106 that transmits the abnormality detection information immediately drives the alarm 111 to generate a strong alarm sound. The powerful alarm sounds that the people around are aware of the intruder and can quickly follow up (report or arrest), and the intruder is also embarrassed and quickly leaves the site. Accordingly, it is possible to improve the security function.

Although the invention made by the present inventors has been described in detail according to the above embodiments, the present invention is not limited to the above embodiments and can be changed in various ways without departing from the gist thereof. It is obvious to those who have it.
