The ice-making observing apparatus according to the present invention includes the unmanned air vehicle (10) and the ice-making observation equipment (20).

The unmanned air vehicle 10 is a device that can be moved by remote operation, and generally means a flying object such as a dragon. The unmanned air vehicle (10) includes an equipment dropping device (11) for mounting the drift ice monitoring device (20) and throwing the drift ice monitoring device (20) on a drift ice at a specific location.

The equipment dropping device 11 includes a hinge 12 for always positioning the drift ice monitoring device 20 in the gravity direction even when the unmanned air vehicle 10 is tilted; And a driving unit 14 for operating the hinge 12 left and right to freely drop the drift ice monitoring equipment 20.

Here, the hinge 12 has a spherical guide surface 13 for guiding the drift ice monitoring device 20 along the surface in the gravity direction even if the unmanned air vehicle 10 is inclined.

The drift ice monitoring device 20 is mounted on the unmanned air vehicle 10 and is dropped into a drift ice of a monitored object or a monitoring area to be freely dropped and fixed to the drift ice, and monitors the drift ice.

The drift ice monitoring apparatus 20 includes a hinge coupling portion 21 coupled to the hinge 12; Fixing means (22) integrally formed with the hinge coupling portion (21) and inserted into the drift ice by free fall; An ice-making monitoring unit (23) mounted on the fixing means (22) and measuring the state of the ice cubes; And a posture guiding portion 24 for maintaining the posture so that the ice-making surveillance equipment 20 maintains the gravity direction when free-fall is installed. Here, the posture guiding portion 24 is preferably composed of a stabilizer fin.

The drift ice monitoring unit 23 includes a satellite navigation device 23a for obtaining current location information and current time information of the drift ice; A solar power generator 23b for converting the heat of the heat collecting plate mounted on the outer surface into electricity and storing the converted electricity in the battery; A wireless communication unit 23c for wirelessly transmitting / receiving data to / from a remote control center; And a control unit 23d for transmitting the location information and / or the drift ice image through the wireless communication unit 23c and receiving a remote control command.

Further, the drift ice monitoring unit 23 may further include a camera 23e for photographing the drift ice and the drift ice.

The operation of the ice-making observing apparatus according to the preferred embodiment of the present invention will now be described in detail.

First, in order to observe the movement of the drift ice, the drift ice monitoring apparatus 20 is mounted on the unmanned air vehicle 10, and the drift ice 1 to which the drift ice monitoring apparatus 20 is mounted through the remote operation of the unmanned air vehicle 10, As shown in FIG. Herein, the unmanned aerial vehicle (10) means a flying object such as a general dragon. Since the actual drone can transport equipment up to 400 kg, it is not difficult to mount various equipment for observing the drift ice 1 to the drift ice to move it to the drift ice 1.

The unmanned air vehicle 10 is equipped with the drift ice monitoring device 20 and the drift ice monitoring device 20 using an equipment dropping device 11 for throwing the drift ice monitoring device 20 into a specific location ).

For example, the equipment dropping device 11 may be configured such that the hinge-engaging portion 21 of the drift ice monitoring device 20 is coupled between the two hinges 12 provided with the spherical guiding surface 13, To the equipment dropping device (11).

Here, the two hinges 12 have a spherical guiding surface 13, and when the two hinges are engaged, the inner surface is hemispherical. The circular hinge engaging portion 21 is engaged with the hemispherical guide surface 13 to mount the drift ice monitoring device 20.

When the unmanned air vehicle 10 moves while the drift ice monitoring device 20 is mounted, the mounted drift ice monitoring device 20 moves on the guide surface 13 of the hinge 12 as well.

At this time, the hinge engaging portion 21 always maintains the posture in the gravity direction regardless of the tilting of the unmanned flying vehicle 10 by the engagement of the circular guiding surface 13 and the circular hinge engaging portion 21.

That is, as shown in FIG. 4A, in the state where the unmanned air vehicle 10 is not inclined, the drift ice monitoring apparatus 20 maintains the gravity direction as it is. When the unmanned aerial vehicle 10 moves while being tilted to one side as shown in FIG. 4B, the hinge coupling part 21 moves along the guide surface 13 to maintain the gravity direction. Therefore, the drift ice monitoring device 20 always maintains the gravity direction irrespective of the inclination of the unmanned air vehicle 10.

Next, when the moving unmanned flying vehicle 10 arrives at the upper portion of the drift ice 1 for mounting the drift ice monitoring device 20, the driving portion 14 of the equipment dropping device 11 operates to rotate the hinge 12 To the left and right to open the hinge 12. That is, the two hinges are moved to the left and right sides, respectively. Here, the driving unit 14 preferably uses a driving device such as a cylinder, a monitor or the like.

When the space is formed by the hinge 12 and the space in which the space is formed is larger than the hinge engaging portion 21, the hinge engaging portion 21 freely falls due to gravity.

The drift ice monitoring device 20 in which the free fall is caused to fall down due to the force of gravity and gravity acceleration.

At this time, in order to guide the drift ice monitoring equipment 20 falling down to the unmanned air vehicle 10 to fall down in the vertical direction (gravity direction) with respect to the drift ice 1, the posture inducing unit 24 ) Maintains the posture of the drift ice monitoring device 20. Here, the posture inducing unit 24 may use a mechanism such as a stabilizer fin. That is, as shown in FIG. 3A, by implementing the four wing shapes, the drift ice monitoring device 20 can be vertically dropped on the drift ice 1. 4C shows a state in which the drift ice monitoring device 20 is free to fall vertically.

The freezing falling ice monitoring device 20 descends due to gravity and speed and the fixing pin 22 as the fixing means 22 mounted on the lower portion penetrates the drift ice 1 and moves the drift ice monitoring device 20 to the drift ice 1. [ . It is also possible to use various fixing means for fixing a specific object to the drift ice 1 in addition to the fixing pin 22 here. 5 is an example in which the drift ice monitoring device 20 is mounted on the drift ice 1 by the fixing means 22. [

In a state where the drift ice monitoring apparatus 20 is normally mounted on the drift ice 1, the drift ice monitoring unit 23 observes the drift ice condition and wirelessly transmits the drift ice observation data to a remote control center.

For example, the control unit 23d of the drifting ice monitoring unit 23 calculates the current location and time information of the drift ice obtained through the GPS 23a in real time, and the drift ice image and the surrounding image generated through the camera 23e as necessary And generates the observed observation data. That is, the shape of the drift ice and the surrounding drift ice image are obtained in real time through the camera 23e, and the drift ice observation data is generated by mapping the position information and the time information acquired through the GPS 23a and the image information. The generated observation data of ice cubes are wirelessly transmitted to a remote control center through the wireless communication unit 23c. Thus, the remote control center can manage the life cycle of the drift ice such as the drift process, the drift process, and the route of the drift ice in real time without directly observing the drift ice. By using the management data of the drift ice to predict the drift of the drift ice and providing the drifting route for drift ice when the drift is performed on the basis of the drift drift route, it is possible to prevent the drift ice from colliding with the ship or colliding with the drift ice will be. In addition, since it is possible to consider the movement of drift ice when installing a fixed offshore structure, it is possible to envisage a practical scenario of drift ice collision, and it is advantageous to design the drift ice considering the drift.

Here, the present invention has been described in connection with the case where the current position information and the time information of the image and the drift ice together with the camera are used to generate the drift ice observation data. However, this is an embodiment, and a camera may not be used in another embodiment. When the camera is not used, only the current position information and the time information of the drift ice through the GPS 23a are generated as the drift-observation data and transmitted to the remote control center through the wireless communication unit.

On the other hand, in order to mount the drift ice monitoring device 20 in the drift ice 1 for a long time and observe the drift ice, a power capable of driving the drift ice monitoring device 20 is required. For this power, the solar photovoltaic device 23b is used in the present invention. The photovoltaic power generator 23b uses a general photovoltaic power generator that converts ordinary solar heat into an electric signal and stores it in an internal battery. It is preferable that the heat collecting plate be mounted on the outer surface of the drift ice monitoring unit 23 or on the outer surface of the posture guiding unit 24. [ By using the photovoltaic power generation device 23b in this manner, it is possible to observe the drift ice for a long time without providing additional power.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to a technique of moving an ice-making ice monitoring device to a position of an ice-making ice by using an unmanned aerial vehicle, and real-time monitoring of the ice-making ice by mounting an ice-making observation device to the ice-making ice unattended.
