On the other hand, networks include closed networks such as LAN (Local Area Network) and WAN (Wide Area Network), open networks such as the Internet, as well as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), and GSM ( Global System for Mobile Communication), Long Term Evolution (LTE), Evolved Packet Core (EPC), and other networks, as well as next-generation networks and computing networks to be implemented in the future.

Referring to FIG. 1, the system for detecting a building risk due to an earthquake according to the present embodiment includes a vibration detection device 100 and a building risk analysis server 200.

The vibration sensing device 100 is installed in a building and detects vibration generated. The vibration detection device 100 may be a vibration detection sensor. At this time, the vibration may be a vibration caused by a natural earthquake and/or a vibration caused by an artificial earthquake (eg, blasting). The vibration sensing device 100 may sense vibrations that are installed in a building and occur, and generate and transmit the sensed vibrations as vibration signals. In this case, the vibration signal may include location information of a building in which the vibration detection device 100 is installed, frequency information, depth information of the epicenter, information about generation of sound waves, and the like.

The building risk analysis server 200 may receive a vibration signal from the vibration detection device 100 and analyze it to determine whether the vibration detected by the vibration detection device 100 is a seismic wave. The building risk analysis server 200 receives a vibration signal from the vibration detection device 100 and analyzes the vibration signal to determine whether it is a seismic wave. At this time, the building risk analysis server 200 may determine whether the vibration detected by the vibration detection device 100 is a seismic wave by comprehensively considering and analyzing the vibration signal. Specifically, the building risk analysis server 200 comprehensively considers and analyzes the vibration signal, but when the depth information of the epicenter according to the vibration satisfies a preset condition, and the sound wave according to the vibration does not occur, the vibration detection device 100 It can be determined that the vibration detected by) was caused by an earthquake. In general, when an earthquake occurs, the depth of the epicenter is approximately 10 to 15 km, and sound waves hardly occur. On the other hand, in the case of an artificial earthquake (eg, blasting, etc.), the depth of the epicenter occurs near the earth's surface, and the sound waves generate aerial sound waves. Accordingly, the building risk analysis server 200 may determine whether the vibration is caused by a natural earthquake or an artificial earthquake (eg, blasting) if these conditions are considered.

The building risk analysis server 200 may analyze the risk of collapse of the building and provide information on the analyzed result when it is determined that the generated vibration is a seismic wave. The building risk analysis server 200 may transmit information on the analyzed result to a portable terminal or to the alarm unit 110. At this time, the alarm unit 110 is installed in a place that is good for people to jump on, such as a ceiling and/or a pillar of a building, and emits a warning signal through a light such as an LED, and the result of analysis from the building risk analysis server 200 When the information on is received, when a warning message is included in the received information, light is emitted through the alarm unit 110 so that people in the vicinity may recognize the danger of an earthquake.

Meanwhile, the system for detecting the danger of buildings due to an earthquake according to an embodiment of the present invention may further include a distance measurement sensor 120 and a monitoring target unit 130.

When the vibration signal received from the vibration detection device 100 is determined to be a seismic wave, the distance measurement sensor 120 and the monitoring target unit 130 are used to detect whether a building collapses due to an earthquake. It can be installed at a certain distance apart from each other on a scene or on the wall of a building. More specifically, the distance measurement sensor 120 and the monitoring target unit 130 are installed at a certain distance apart from each other on the ceiling surface of the building or the wall surface of the building, and are installed in pairs to face each other as shown in FIG. It is preferable that, in FIG. 2, it is described that only one pair of the distance measurement sensor 120 and the monitoring target unit 130 is installed, but is not limited thereto, and a plurality of them may be installed. In this case, the distance measurement sensor 120 may measure the distance d1 to the monitored unit 130 before the earthquake occurs and store it in a storage unit (not shown). In more detail, the distance measurement sensor 120 measures the distance d1 to the vertex of the monitored part 130 facing before the earthquake, when the monitored part 130 has a triangular pyramid shape as described later. It can be stored in a storage unit (not shown).

On the other hand, the building risk analysis server 200, when determining that the vibration detected by the vibration detection device 100 is caused by an earthquake, distance information measured from the distance measurement sensor 120 to the monitoring target unit 130 ( d2), and comparing the difference between the distance information (d1) stored in the storage unit (not shown) and the distance information (d2) received at the time of an earthquake to a preset threshold to determine whether the building is at risk of collapse. have.

More specifically, the monitored part 130 may be in the shape of a triangular pyramid. When the monitored part 130 is in the shape of a triangular pyramid, one vertex faces the distance measurement sensor 120 and connects the remaining three vertices. It is preferable that the surface to be installed is parallel to and adjacent to the ceiling surface of the building and/or the wall surface of the building. In this way, when the monitored part 130 is installed in a pair to face the distance measurement sensor 120 in the shape of a triangular pyramid, it is measured when warping or distortion occurs in the ceiling and/or wall of the building due to an earthquake. Depending on the difference in distance information, it is possible to more accurately determine the danger situation of the building (eg, risk of collapse, etc.). That is, when the building is in a stable state, the distance measured to the vertex of the triangular pyramid that is the monitoring target unit 130 that the distance measurement sensor 120 faces (d1 in FIG. 2) is, when an earthquake occurs, the distance measurement sensor 120 of the building ) Is shorter than the distance measured to the monitoring target unit 130 (d2 in FIG. 3). That is, when an earthquake occurs, the ceiling and/or the wall may be deformed according to the warping or warping of the structure of the building. In this case, the distance measurement sensor 120 is a triangular pyramid other than the vertex of the triangular pyramid that is the monitoring target unit 130 The distance to the edge and/or face of is measured (see Fig. 3). At this time, when the difference between d2 and d1 is compared with a preset threshold and the preset condition is not satisfied (for example, when the difference between d2 and d1 is less than the threshold), the warpage and/or warpage of the building is severe. It can be judged that the building is in danger of collapse.

On the other hand, the building collapse risk analysis server, when it is determined that the building is at risk of collapse, may transmit information on the analyzed result, for example, information on the collapse risk analysis of the building. At this time, the building risk analysis server 200, when it is determined that the building is at risk of collapse, based on the location information of the building included in the vibration signal, information on the result of analysis by a user terminal within a preset danger radius Or may be transmitted to the alarm unit 110 in the building. Accordingly, the user who receives the information on the collapse risk analysis of the building due to the earthquake through the user terminal is out of the danger radius of the building that is the target of collapse, or the person located in the building with the risk of collapse recognizes the warning of the alarm unit 110 And evacuate outside the building. In addition, the building collapse risk analysis server transmits information on the analyzed result to the user terminal within a preset danger radius based on the location information of the building included in the vibration signal, but does not stop simply transmitting the information. , It is also possible to sequentially transmit information about the analyzed result to the user terminal according to the priority of a preset danger radius. In this way, when information about the analyzed result is sequentially transmitted to the user terminal according to the priority of a preset danger radius, information related to the risk of collapse is transmitted to users in a close distance to the building in which the risk of collapse exists It has the effect of quickly getting out of a dangerous situation.

Referring to FIG. 4, first, a building collapse risk server receives a vibration signal from the vibration detection device 100 (S410).

Next, the building collapse risk server analyzes the vibration signal to determine whether it is a seismic wave (S420). In this case, the vibration signal may include location information of a building in which the vibration detection device 100 is installed, frequency information, depth information of an epicenter, information about generation of sound waves, and the like. More specifically, the building collapse risk server comprehensively considers and analyzes the vibration signal, but when the depth information of the epicenter according to the vibration satisfies a preset condition, and the sound wave according to the vibration does not occur, the vibration detection device 100 It can be determined that the vibration detected by is caused by an earthquake.

Next, the building collapse risk server, when it is determined that the vibration generated as a result of the analysis is a seismic wave, analyzes the collapse risk of the building and provides information on the analyzed result (S430).
