The main body 101 may include respective components of the block diagram shown on the right side, and the solar panel 102 may be installed on the upper part of the main body 101 to receive sunlight and convert it into electrical energy. The solar panel 102 may have a maximum conversion efficiency of about 22%, but the scope of the present invention is not limited thereto.

The short range communication antenna 103 is an antenna for short range communication with the repeater 200, and the indicator 104 is for displaying various notifications (for example, power shortage, device abnormality, etc.).

The support base 105 supports the main body 101, and at least a portion thereof is directly buried in the ground of the slope to fix the measurement device 100 to any position on the slope.

Assuming movement, the location of each layer apparatus 100 may be temporarily determined. Thereafter, the positioning unit 220 corrects all of the measuring devices by using the distances from the measuring devices 100a to 100e to the adjacent measuring devices (for example, the distance between 100c and 100e in the case of 100d). The three-dimensional coordinates satisfying the distance between the measuring devices 100a to 100e and the distance between the measuring devices 100a to 100e and the distance from the repeater 200 can be determined.

The three-dimensional coordinates of each of the measurement apparatuses 100a to 100e determined as described above may be used to estimate a change of the current slope.

6 is a view illustrating the management server shown in FIG. 1 in more detail.

Referring to FIG. 6, a front view of an implementation of the management server 300 is shown on the left side of FIG. 6, and a block diagram briefly illustrating a configuration of the management server 300 is shown on the right side of FIG. 6.

First, the management server 300 may be implemented as one single server as shown on the left side of FIG. However, the scope of the present invention is not limited thereto, and may be implemented as a plurality of servers that can communicate with each other.

Next, referring to the block diagram of the configuration of the management server 300, the management server 300, the wireless communication unit 310, information collection unit 320, risk determination unit 330, the main control unit 340, The update manager 350 and the notification controller 360 may be included.

The wireless communication unit 310 is a configuration capable of transmitting and receiving data in a mobile communication method so as to transmit and receive data with the repeater 200, as described above, according to the technical standards or communication methods for mobile communication Let's assume.

The information collection unit 320 may store sensing data received from the repeater 200 distributed in various regions, and provide sensing data at the request of the risk determination unit 330 or the main control unit 340.

The risk determination unit 330 may generate landslide state data of a slope on which the repeater 200 is located based on the sensing data stored in the information collection unit 320, and the landslide state data may be transmitted to the main control unit 340. Can be.

Landslide state data may include state information of any one of landslide safety, landslide boundaries, landslide warnings and landslide alerts on slopes. Here, landslide safety means a state where landslides are unlikely to occur, landslide boundary means a state in which landslides have not occurred but are likely to occur, and signs of landslides indicate a state in which an early landslide situation is suspected. A landslide alert may mean a condition in which a landslide has occurred.

According to an embodiment, the risk determination unit 330 may determine landslide state data based on the impact amount data of the sensing data. For example, when the impact amount (digital value) calculated by Equation 1 of FIG. 3 is 1000 or more, the risk determination unit 330 may determine that the slope where the relay 200 is located is a landslide warning state. And, when the impact amount (digital value) is a value between 200 and 600, the risk determination unit 330 may determine that the slope where the repeater 200 is located is a state of landslide signs. The impact amount 1000 corresponds to about 0.5 g in terms of acceleration value, and the impact amount over 0.5 g corresponds to the impact amount equivalent to level 3 or more in the modified mercali progress class announced by the Korea Meteorological Agency. The impact amounts 200 and 600 correspond to about 0.2 g and 0.3 g in terms of acceleration values, and the impact amounts in the above range correspond to the impact amount corresponding to class 2 in the modified mercali progress class announced by the Korea Meteorological Administration.

Here, the amount of impact that is the basis for determining the state of the slope where the repeater 200 is located may be the amount of impact of any one of the plurality of measuring devices 100 connected to the repeater 200, Average impact amount. If the impact amount of any one of the plurality of measuring devices 100 is based, a high impact amount may be generated by an impact by an animal or a person, not by a landslide, so that it is adjacent (for example, located vertically downward). The state determination may be made by additionally referring to the impact amount of the other measurement device 100.

According to an embodiment, the risk determination unit 330 may determine landslide state data based on the slope data of the sensing data. For example, when the average slope of the plurality of measuring devices 100 is in the first range (for example, 10 to 20 degrees), the risk determination unit 330 may cause landslides on the slope where the repeater 200 is located. It can be determined that the state of. For example, when the average slope of the plurality of measuring devices 100 is in the second range (eg, 30 degrees or more), the risk determination unit 330 may determine that the slope where the repeater 200 is located is a landslide alarm. It can be determined that the state.

According to an exemplary embodiment, the risk determiner 330 may consider the change in the area of the polygons, the inclination of the polygons, the degree of deformation of the polygons, etc. from the three-dimensional coordinates of each measurement device of the sensing data. It is possible to determine the state of the slope where) is located.

According to an embodiment, if an abnormality is found in the temperature data, humidity data, and illuminance data of the sensing data, the risk determination unit 330 may determine that the slope where the relay 200 is located is a landslide boundary state. That is, since landslides are more likely to occur in an environment with high temperature and humidity and low illuminance, when the sensing data satisfies these conditions, the risk determination unit 330 determines that the slope where the relay 200 is located is a landslide boundary state. can do. In addition, the risk determination unit 330 may determine that the slope where the relay 200 is located is a state of landslide boundary not only from the sensing data but also from a weather forecast (for example, a predetermined rainfall or more) provided by the Meteorological Agency.

According to an embodiment of the present disclosure, the risk determination unit 330 may determine the state of the slope on which the repeater 200 is located by comprehensively considering the state of the impact data, the slope data, and the polygons formed by the measurement devices. have. For example, only when two or more conditions among impact data, slope data, and polygonal conditions satisfy the conditions of a landslide warning or a landslide warning, the risk determination unit 330 determines that the slope on which the relay 200 is located is a landslide warning or landslide. It can be determined that the state of the alarm.

The main control unit 340 controls the overall operation of the management server 300, and transmits control data to the relay 200 according to the landslide state data of the risk determination unit 330, or to each notification device (400 to 600) Alert data can be delivered.

In detail, when the landslide state data indicates a landslide boundary, the main controller 340 may transmit control data for controlling an operation cycle of each measurement apparatus 100 to the repeater 200.
