Returning to the description of FIG. 6, if it is determined in step S740 that the user is a room, the access status and the room status of the building are transmitted to the mobile terminal 800 (S760).
If it is determined in step S740 that the user is not a redundant room, it is determined whether an intruder has occurred. If it is determined in step S750 that an intruder exists, the intrusion detection information is transmitted to the mobile terminal 800 in step S770.
Hereinafter, various methods of notifying a dangerous situation using the dangerous situation notification system of FIG. 5 will be described. Below, it is assumed that a sensing device 500 is installed in a window and a front door of an apartment where a family of four parents, mother, son, and daughter lives, and a relay device 600 is installed in the living room.
1) When mom and dad return
When the father and the mother open the door, the server 700 transmits the opening / closing information collected through the sensing device 500 to the server 700 through the relay device 600. When the opening / closing information is received, Stores the location of the sensing device 500 and transmits the push message to the mobile terminal of the dad, mother, son, and daughter.
The mobile terminal 800 of the father, the mother, the son, and the daughter transmits the AP signal detection result to the server 700 in response to the push message, respectively, and the server 700, , Son, and daughter. At this time, since the dad and the mother enter the front door, they are judged to be a room occupant because they are within the AP signal range of the relay apparatus 600.
If the intrusion is not detected based on the result of judgment of the dad, mother, son and daughter, and the existing ladies' situation, if the intrusion is not detected, And transmits it to the daughter's mobile terminal 800.

2) When my son goes out
When the son opens the front door, the server 700 transmits the opening / closing information collected through the sensing device 500 to the server 700 through the relay device 600. When the opening / closing information is received, (500), and sends a push message (primary) to the mobile terminal of the father, mother, son, and daughter.
Then, based on the detection result of the AP signal transmitted from the mobile terminal 800 of the father, mother, son, and daughter, it is determined whether or not the father, the mother, the son, and the daughter are absent. At this time, if the son's mobile terminal 800 is present within the AP signal range, the result of the re-availability analysis is as shown in Table 5 below.

As shown in Table 5, when the existing occupant is the same as the occupant who is detected, the push message (secondary) is transmitted to the mobile terminal of the father, mother, son, and daughter after a preset time. If the son is out of the front door and is not within the AP signal range, the results of the reacquisition analysis are shown in Table 6 below.

FIG. 8 is an output example of the loudness situation analysis result according to one embodiment of the present invention.
Referring to FIG. 8, the result of the redundancy analysis of Table 2 and Table 4 is transmitted to the mobile terminal of the father, mother, son, and daughter and outputted.
According to the embodiment of the present invention, the wireless communication of the mobile terminal can be started through the push message transmitted from the server, and the signal of the access point can be sensed to judge whether or not the mobile terminal user is re-installed. Also, the risk / invasion situation information and the evacuation information can be provided based on the availability and location of the mobile terminal user. As a result, the danger / invasion situation information provided to the user and the effectiveness of the evacuation information can be improved.
While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It belongs to the scope.
