4 is a flowchart illustrating a method of automatically releasing a lock mode of a digital door lock when a disaster situation occurs according to an embodiment of the present invention.

First, the home server 120 installed in each home for home network service checks whether or not a disaster occurs in the home using various sensors 140 and 150 connected thereto. In this case, fire detection using a temperature sensor and a gas sensor, gas leak detection using a gas sensor, an earthquake detection using a vibration sensor, and an outside intrusion detection using an infrared sensor may be checked. A fire detection case using a sensor will be described as an example (S410).

When the high temperature sensor is sensed by the temperature sensor or the toxic gas is detected by the gas sensor, the temperature sensor transmits the detected data to the home server 120. In this case, the various sensors and the home server 120 may be connected by wire or wirelessly. When the sensor and the home server 120 are connected wirelessly, the home server 120 should receive sensing data using the wireless transceiver 1210 or separately include a module for communication with the sensor (S420). .

When the home server 120 receives the fire detection data from the sensor through a wired or wireless connection, the home server 120 requests the transmission of a disaster occurrence message indicating that a fire has occurred to the mobile communication network through the communication module 1250. In this case, the disaster occurrence message transmission request signal transmitted from the home server 120 to the mobile communication network may include a mobile terminal number of the user who will transmit the message and a disaster occurrence message phrase. The mobile communication network transmits a disaster occurrence message phrase transmitted to a mobile terminal having a mobile terminal number transmitted by using a short message service (SMS) server or a multimedia message service (MMS) server.

At this time, the telephone number of the notification target mobile terminal according to the identification number of the home server 120 and the identification number according to various disaster situations are set in advance in a specific service server of the mobile communication network, and the identification is made from the home server 120.

To send). However, if the digital door lock 110 does not receive the lock mode release command or fails to release the lock mode of the digital door lock 110 due to a malfunction due to a fire, the release completion signal is transmitted to the home server 120. It doesn't work.

Accordingly, the home server 120 should check whether the release completion signal is received from the digital door lock 110 (S460).

At this time, when the release completion signal is not transmitted due to non-reception or malfunction of the lock mode release command of the digital door lock 110, the lock mode release command signal is retransmitted to the digital door lock 110.

Although the step of retransmitting the lock mode release command signal as described above is repeated by a predetermined number, when the release completion signal is not transmitted from the digital door lock 110 (S462), the mobile communication network is communicated through the communication module 1250. Request to send a message indicating that the lock mode of the digital door lock cannot be changed. The lock mode change impossible message of the door lock is transmitted to a previously set notification target mobile terminal or a home server managing server managing the home server 110 through a short message (S464).

The digital door lock 110 in which the lock mode is released according to the lock mode release command continuously maintains the open state (S470) and checks whether a disaster occurrence cancel signal is input. Disaster occurrence termination signal is input by the user who manages the home server management server or the user who received the disaster occurrence message in step S430 when it is confirmed that there is a malfunction when the fire is extinguished. It may be (S480).

When the disaster occurrence termination signal is input, the sensor is reset, and the lock mode setting / release of the digital door lock 110 is changed back to the automatic mode to return to the original state (S490).

Through such a method, when a disaster situation occurs, the home server 120 may automatically release the lock mode of the digital door lock 110.

The embodiments of the present invention described above are not only implemented by the apparatus and method but may be implemented through a program for realizing the function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded, The embodiments can be easily implemented by those skilled in the art from the description of the embodiments described above.
