The present invention relates to an apparatus for automatic opening and closing of a door for sensing an earthquake to minimize injury to human life in an earthquake, and, more specifically, to an apparatus for automatic opening and closing of a door for sensing an earthquake, which is capable of preventing a fixation accident of the door due to changes to a door frame and a door during an earthquake, and effectively preventing injury to human life when an earthquake occurs. The apparatus for the automatic opening and closing of the door for sensing an earthquake has the following effects. First, because the door and an emergency exit can be operationally opened by receiving, by wired and wireless transmission, an earthquake occurrence signal transmitted from a government agency or a seismic trigger installed inside/outside a building, residents in the building can safely take refuge during an earthquake while allowing normal operation of a door in a non-disaster situation. Second, an auxiliary power unit is included in case of an electrical grid interruption that may occur during an earthquake, and therefore, the door is configured to be capable of operation for a period even when the electrical grid is interrupted, thereby ensuring operation of the door even in a disaster situation. As stated above, the present invention can be expected to minimize injury to human life during an earthquake. |
