Description

MARINE OBSERVATION FLOATING BODY}

The present invention relates to a floating body for ocean observation, and more particularly, to a floating body for ocean observation capable of increasing the efficiency of receiving data between floating bodies for ocean observation while maintaining the balance of floating bodies.

In addition to being difficult to maneuver due to the nature of the installation location of the ocean, the ocean observation system is limited to the collection of observation data and the control of the observation equipment. Therefore, And periodically collecting it, or controlling the observation device by wireless communication and transmitting / receiving the observation data are generally used.

These marine observing devices can be installed to cover a certain range when installed in the ocean, and each of the marine observation devices transmits and receives the collected data to the other marine observation devices by using the RF short range wireless communication.

However, the RF short-range wireless communication method used between each marine observation device is a low-power wireless communication protocol which requires a low cost for the module and equipment, but its use range is limited and the number of marine observation devices must be increased There is a problem that a large cost is incurred.

Therefore, even if the same number of marine observation devices as the existing ones are used by using the low-power long-distance wireless communication method, there is a need to cover a wider range. Therefore, it is essential to improve data reception efficiency when using a low-power long-distance wireless communication method between marine observation devices.

In addition, it is very important for the marine observation device to maintain a balance in the ocean. In general, the balance is maintained by connecting a weight of a metal or ore having a predetermined weight to a connection ring formed at a lower portion of the marine observation device.

However, when the weight is separated due to external impact, defective connection with the connection ring, breakage of the wire, etc., there is a problem that the marine observation device is lost.

Also, when a large number of marine observation devices are used, there is a problem that the cost burden due to the weight of the metal or ore is increased.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a floating body for marine observation, which not only increases data receiving efficiency between marine observation devices but also requires no weight for maintaining balance, do.

In order to achieve the above object, a floating body for ocean observation according to an embodiment of the present invention includes an upper body, a lower body coupled to the upper body and constituting the body of the floating body for observation of the ocean, And a communication device mounted within the lower body for establishing a center of gravity, the communication device comprising: a housing; a signal receiver located in a first space of the housing and receiving and inputting a signal received from a first peripheral body; A cavity filter which is disposed in a second space of the housing and is connected to the cavity filter through an output loop and which receives a signal of a specific frequency band filtered by the cavity filter through the output loop, A receiving circuit board and a circuit board disposed on the circuit board, wherein the seawater information measured from at least one of the internal sensor and the external sensor And a control unit for collecting the seawater information of the first peripherals and the signal contained in the received signal, and controlling the first and second peripherals to be transmitted to the second peripheries, And is divided by the bottom surface of the filter.

According to an embodiment of the present invention, it is possible to transmit and receive a desired signal through a cavity filter suitable for high power in communication between marine observation devices, and to increase data receiving efficiency.

In addition, by increasing the data reception efficiency, it is possible to cover a wider range even when using the same number of marine observation devices as before. That is, it is easy to expand the cover range.

In addition, since the cavity filter mounted in the marine observation device forms the center of gravity, it is not necessary to provide a structure for a separate center of gravity such as the center of gravity.

Further, since the main components such as the circuit board are accommodated in the cavity filter formed in a two-layer structure, the main components can be protected from external shocks, pollution, heat generated by solar cells, and the like.

It should be understood that the effects of the present invention are not limited to the above effects and include all effects that can be deduced from the detailed description of the present invention or the configuration of the invention described in the claims.

[

The tuning bolt (not shown) may be positioned above the resonator (not shown) through the upper surface of the housing 111 and may be fixed to the upper surface of the housing 111 as a metal material by screwing.

Therefore, the distance between the tuning bolt (not shown) and the resonator (not shown) can be adjusted by rotation, and the tuning can be performed by varying the distance between the resonator (not shown) and the tuning bolt (not shown).

On the other hand, the circuit board 113 can be disposed in the second space in the housing 111.

The communication device 110 has been described with reference to FIG. 2. Hereinafter, the communication between the upper and lower bodies 120 and 130 will be described.

The upper body 120 and the lower body 130 may be coupled to each other to form a body of the body 100. [

The upper body 120 may be a dome-shaped cover that can be opened and closed, and a solar cell may be disposed on an outer surface thereof.

Here, the 'outer surface' may be composed of a plurality of surfaces having a polygonal shape (rectangular, pentagonal, hexagonal, etc.), or a curved surface such as a hemispherical shape. 3 shows an embodiment in which the outer surface is formed in an octagonal shape.

Further, the upper body 120 may be formed of a reinforced plastic material (e.g., polycarbonate or the like) that can withstand an external sudden impact.

For reference, the LED blinking light for identifying the position of the floating body 100 and indicating the attention to surrounding operation vessels may be located on the surface of the upper body 120 as shown in FIG. 3, As shown in FIG.

If the upper body 120 is formed of a light-transmitting reinforced plastic material, the blinker may be accommodated in the upper body 120.

Also, the communication device 110 can be received and fixed to the inner surface of the lower body 130.

Since the housing 111 is formed of a metal material and a battery or the like is housed therein, the communication device 110 forms the center of gravity of the lifting body 100 by its weight, It is possible to maintain a balance that affects stability.

Generally, a lower portion of the lower body 130 is formed with a connection ring, and a balance weight, which is a heavy material made of metal or ores having a predetermined weight, is connected by wires to maintain the balance of the body 100.

However, since the floating body 100 according to the embodiment of the present invention maintains the balance of the communication device 110 having the metal housing 111 in the lower body 130 due to its weight, There is an advantage that it is not necessary.

In addition, a through hole (not shown) is formed in the lower body 130 so that external sensors capable of measuring the temperature, salinity, flow rate, turbidity due to microorganisms, red tide, etc. of the seawater are drawn out through the wiring wire And a packing material can be inserted into the through hole (not shown) for watertightness.

In addition, since the main components such as the circuit board are housed in the communication device 110 formed in a two-layer structure, the main components can be protected from external shocks, pollution, heat generated by solar cells, .

For reference, the external sensors may be drawn out through the wiring wire as described above, or may be attached to the outer surface of the lower body 130, depending on the embodiment.

In addition, the lower body 130 may be filled with a filler for watertightness of the communication device 110. [
