The winch 151 winds or loosens the wire supporting the second body 110b to move the second body 110b upward and downward with respect to the first body 110a.

The sensor 180 detects the shaking of the main body 110. The sensor 180 may be, but is not limited to, an acceleration sensor.

The control unit 240 may receive a sensing signal of the shaking of the body from the sensor 180. [ For example, the sensing signal may include information about the direction of the shake or the degree of shake. The control unit 240 may continuously or periodically receive the detection signal from the sensor 180. [

Once the controller 240 receives the sensing signal from the sensor 180, the controller 240 controls the driving unit 150 to vary the sliding length of the second body 110b with respect to the first body 110a. The control unit 240 controls the first body 110a and the second body 110b so that the shake of the main body 110 can be minimized or reduced while receiving the detection signal from the sensor 180 continuously or periodically. The sliding length can be adjusted.

When the main body 110 having the cylindrical shape extending in the up-and-down direction is shaken by an external force such as wind during flight, the flying body 100 'according to the above- The shaking of the main body 110 can be minimized or reduced. Accordingly, the flight body 100 'can maintain a stable posture in the air.

Alternatively, the control unit 350 may transmit the ID information of the user (U) stored in advance to the central control station. The ID information may include the name of the user U, a contact, and the like.

The central station can monitor the risk of the user U through the received image, and if necessary, transmit the location information and ID information of the received terminal 30 to the police station.

The control unit 350 can identify the user U and the user around the user in the received image.

For example, the control unit 350 can identify a person located in the central area of the image by the user U, and can specify a person located in an area other than the central area of the image as a person around the user.

For example, a pattern of an image taken when a person walks or runs in the air can be stored in advance in the storage unit 360 of the terminal 30. [ The control unit 350 can recognize an object having a pattern identical or similar to a pattern stored in advance in the received image as a person.

For example, a ladder pattern photographed by a thermal camera can be stored in the storage unit 360 of the terminal 30 in advance. When the received image is photographed by the camera module 210 of the thermal camera type, the controller 350 can recognize the object having the same or similar pattern as the previously stored thermal image in the received image as a person.

In this manner, the control unit 350 can distinguish a person from an object in the received image.

The control unit 350 can display a warning alarm when the user around the user is identified in a continuous manner for a predetermined time period through the received image. The warning alarm may be displayed through the display module 340 or through a speaker mounted on the terminal 30. [

Meanwhile, an application for implementing the risk monitoring method using the drones 10 may be installed in the terminal 30. The user can execute the application and control the operation of the drones 10 and the operation of the terminal 30 described above.

Alternatively, the drone 10 may be equipped with a separate program for controlling the operation of the drones 10 described above.
