It is a diagram schematically showing a configuration for managing phrases based on transmitted data.

The low-power wide area communication-based fishing gear identification smart buoy 100 and the gateway system 200 for a fishing vessel according to an embodiment of the present invention shown in FIGS. 1 and 2 is a smart buoy 100, a fishing vessel 210, and a fishing vessel control. It includes a system 250 , a land base station 220 , a land control system 230 , and a management vessel (not shown).

The smart buoy 100 receives a GPS signal of the current location from the satellite 240 in a state connected to the fishing gear and transmits coordinate information to the fishing vessel 210, or when the connected fishing gear is lost, the fishing gear loss information is transmitted to the fishing vessel 210. send Since the smart buoy 100 is floating on the sea level for a long time, it is necessary to reduce energy consumption. Therefore, coordinate information can be transmitted to the fishing vessel 210 according to a preset period. At this time, the smart buoy 100 may transmit coordinates and loss information to the fishing vessel 210 based on low-power wide area communication.

Low-power wide area communication can improve compatibility with the Internet of Things network in use by using a frequency of 900 MHz. Low-power wide area communication can reduce the power consumption of the smart buoy 100 by using the LoRa protocol, which is characterized by a small bandwidth and a wide communication range.

The fishing vessel 210 includes a gateway 215 for the fishing vessel.

The sensor 310 detects whether the fishing gear connected to the smart buoy 100 is lost. The sensor 310 may be a pressure sensor or a magnetic sensor. The pressure sensor detects whether the gear is lost based on the pressure change of the gear coupling part connected to the smart buoy 100 and the gear. That is, the pressure sensor senses the reduced pressure due to the breakage of the gear when the gear is cut in the gear coupling part. The magnetic sensor detects whether or not the fishing gear is lost based on a change in the magnetic intensity of the smart buoy 100 and the gear coupling part connected to the fishing gear.

The phrase identification unit 320 stores identification information of the smart buoy 100 and the phrase to identify a plurality of smart buoys 100 and the phrase, respectively. That is, when fishing gear is lost from a specific smart buoy 100 among a plurality of smart buoys 100 floating at sea level, the control system can identify the lost smart buoy and the lost fishing gear through the identification information.

The antenna unit 330 includes a GPS antenna 334 and a low-power wide area communication unit antenna 338 connected to the GPS unit 320 and the low-power wide area communication unit 350 .

The low-power wide area communication unit antenna 338 uses a dipole antenna, and the GPS antenna 334 may be located at an upper end of the dipole antenna. Alternatively, the antenna unit 330 may be a dual-band antenna capable of simultaneously performing the roles of the GPS antenna 334 and the low-power wide area communication unit antenna 338 .

The GPS unit 340 receives the GPS signal from the satellite 240 through the GPS antenna 334 and derives the GPS coordinates of the smart buoy 100 .

The low-power wide area communication unit 350 transmits identification information, coordinate information, and fishing gear loss information of the smart buoy 100 to the fishing vessel 210 and the control center through the low-power wide area communication unit antenna 338 .

The control unit 360 receives whether the fishing gear is lost from the sensor 310 and transmits the loss information to the fishing vessel 210 and the control center through the low-power wide area communication unit 350 when the fishing gear is lost.

The power supply unit 370 supplies power necessary for the operation of the smart buoy 100 .

As described above in FIG. 3, the sensor unit 310, the phrase identification unit 320, the GPS unit 340, the low-power wide area communication unit 350, and the control unit 360 reduce the power consumption of the smart buoy 100, A low-power device can be used, and it can be set to operate according to a set cycle.

The first region 510 includes an antenna unit 330 inside, and a handle unit 410 providing a gripping feeling is formed outside. In addition, the phosphor paint 420 is applied to the outer surface of the first region 510 including the handle portion 410 .

Since the description of the antenna unit 330 has been described in detail with reference to FIG. 3, the detailed description will be omitted.

The handle portion 410 provides a sense of grip to the smart buoy 100 , and includes a curved portion 413 , a hook portion 416 , and a support portion 419 .

The curved portion 413 is configured to prevent the handle portion 410 from sliding in the hand, and has a gentle curved surface on the upper surface of the first region 510 of the body portion 500, and the central portion is formed in a convex shape. . The curved portion 413 includes a plurality of grooves 414 or a plurality of protrusions (not shown) that provide frictional force to the convex central portion. That is, when a person grabs the handle portion 410 of the smart buoy 100 by hand and throws it to the sea level, or recovers the smart buoy 100 floating on the sea level, the curved portion 413 is located in the palm of the hand and is in close contact. By being, the handle portion 410 is prevented from sliding in the hand.

The hook 416 is formed to protrude under the first region 510 of the body 500 .

The hook portion 416 is formed to protrude from the lower portion of the first region 510 and is fitted between the index and middle fingers, thereby improving gripping force. Preferably, the protruding thickness of the hook portion 416 may be formed to be about 2/3 of the thickness of a finger.

The support part 419 is formed to protrude above the first region 510 of the body part 400 to support the back part of the palm.

The support part 419 is spaced apart from the hook part 416 by a predetermined length and is formed to protrude on the upper portion of the first region 510 , so that it is in close contact with the back part of the palm. The preset length may be 5 to 7 cm. Preferably, the protruding thickness of the support part 419 may also be formed to be about 2/3 of the thickness of a finger like the hook part 416 .

In addition, the support part 419 is formed to be inclined downward at an angle of 15° to 30° toward the lower side toward the hook part 416 . Since the support part 419 is formed obliquely in this way, when the handle part 410 is gripped by hand, the back part of the palm is seated obliquely on the handle part 410. can be effectively supported.

On the other hand, the hook portion 416 and the support portion 419 are formed to be spaced apart at a certain distance, preferably the distance between the hook portion 416 and the support portion 419 is the handle portion 410 is held by hand. When, it may be formed at an interval that can be seated from the index finger to the small finger of the finger.

The phosphor paint 420 is applied to the surface of the first region 510 on which the handle is formed to improve the night-time discrimination of the smart buoy 100, and includes a phosphor, an activator, and a co-activator.

[Formula 1] Mn·Al ₂ O ₄

The above formula relates to a phosphor, wherein M is one or more cations selected from the group consisting of calcium, strontium and barium, and n is a number from 0.1 to 1.0 in the above formula.

The activator and co-activator added together with the phosphor defined by the above formula are added by 0.001 to 12 parts by weight and 0.001 to 11 parts by weight based on 100 parts by weight of the phosphor, and then pulverized and mixed. To have a light-emitting effect, boric acid and 1 to 9 parts by weight are added based on 100 parts by weight of the phosphor. In addition, the phosphor paint 420 may be manufactured by firing at a temperature of 1300° C. or higher in an atmosphere of an inert gas or a reducing gas to prevent oxidation during firing.

In this case, the activator may be europium oxide, and the co-activator is one selected from strontium, lanthanum, cerium, praseodymium, neodymium, samarium, gadolinium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, tin and bismuth. It may be more than

Hereinafter, the present invention will be described in more detail with reference to the following examples.

Reagent grade alumina (Al ₂ O ₃ ) 50.98 g (0.5 mol), strontium carbonate (SrCO ₃ ) 73.815 g (0.5 mol), europium oxide (Eu ₂ O ₃ ) 0.71 g (0.002 mol) dysprosium oxide (Dy ₂ O ₃ ) 1.194 g (0.0032 mol), yttrium oxide (Y ₂ O ₃ ) 0.5 g (0.0022 mol) of the mixture was added and mixed for 12 hours while finely pulverized using a ball mill.

After filtering the sufficiently mixed mixture, dry the resulting cake, add and mix 2.524 g of boric acid (corresponding to 2% of the total weight) as a solvent, and flow the dry powder with a hydrogen-nitrogen mixed gas containing 2% hydrogen in an electric furnace. While sending, the temperature was raised to 700 °C, 800 °C, 900 °C, 1000 °C, 1140 °C, 1200 °C, 1300 °C, and 1400 °C, respectively, and then fired for 3 hours and then cooled slowly to obtain a phosphor paint (420) compound.

As in the above manufacturing method, the phosphor paint 420 compound fired at 1300° C. was easy to pulverize, and as a result of measurement using a CS-5 chroma sensor, it was confirmed that the highest wavelength was 520 nm, which is the wavelength band of green.

In order to compare the luminescence duration of the phosphor paint compound 420 of the present invention and the conventional phosphor paint compound containing zinc sulfide and copper as main components, each of the 50 mm × 50 mm × 10 mm crystal containers was filled with a phosphorescent compound. Each of these filled samples was stored by blocking the light for more than 20 hours, then projecting the light for 15 minutes at a distance of 20 cm using a 25 Watt lamp, blocking the light, and measuring the afterglow luminance over time (TOPON BM-5) As a result of measuring with a 2° dioptric angle of the lens, the time it takes to fall below 0.3mCd/m2, the intensity of light that can be recognized by the naked eye, is about 180 minutes compared to the conventional phosphor paint compound. It was confirmed that the phosphor paint compound according to the invention takes more than 1000 minutes.

As can be seen from Example 1, the phosphor paint compound prepared by the method of the present invention is a paint compound that emits green light and emits light for a much longer period of time than the existing zinc sulfide-based paint compound. When applied to a smart buoy, the discrimination power can be improved compared to the prior art. In addition, when the phosphor paint 420 is applied to the first region 510 of the body portion, the surface of the first region 510 in which the handle portion 410 is formed has a property of roughening, so that the grip of the handle portion 410 is reduced. can be further improved.

The second region 520 of the body 500 includes a sensor 310, a phrase identification unit 320, a GPS unit 340, a low-power wide area communication unit 350, a control unit 360 and a power supply unit 370 therein. It includes, and the outside includes a phrase coupling part 440 at the lower end, and is coupled to the floating body part 430 .

Since it has been described in detail with reference to 3, a detailed description will be omitted.

The phrase coupling part 440 is located at the lower end of the second area 520 of the body part and is connected to the gear. When the gear connected to the gear coupling unit 440 is lost, the smart buoy 100 location and gear loss information are transmitted to the fishing vessel 210 and the control center through the configuration inside the second area 520 .

The floating body part 430 may be coupled to the second region 520 of the body part, and has an internal space to impart buoyancy to the smart buoy 100 .

Epoxy resins do not require organic solvents including volatile substances (VOCs), amines, and heavy metals, so they can be used as eco-friendly paints. In addition, epoxy resins are flexible and highly reactive, and have excellent alkali resistance and organic solvent resistance, but are weak against mineral oil and organic acids. On the other hand, silica resin is strong, has excellent abrasion resistance, weather resistance and thermal resistance, and is excellent in acids and solvents, but has a disadvantage in that it has weak alkali resistance.

In order to overcome the above disadvantages, when an epoxy resin and a silica resin are synthesized, they share the characteristics of an organic polymer and an inorganic polymer, so they are strong against acids, alkalis and solvents, and have excellent thermal resistance and UV resistance.

The epoxy resin in the present invention has an epoxy equivalent (g/eq) of 184 to 194, a viscosity (cps@ 25 ℃) of 12000 to 15000, a softening point of 60 to 70 ℃, an epoxy resin or an epoxy having a specific gravity (20 ℃) of 1.17 Use an epoxy resin having an equivalent weight (g/eq) of 450 ~ 500, viscosity (cps@ 25℃) of 12000 ~ 15000, softening point of 60 ~ 70℃, and specific gravity (20℃) of 1.16 ~ 1.20.

The epoxy resin may include at least one selected from a bisphenol A-based epoxy resin, a bisphenol F-based epoxy resin, and a plastic epoxy resin.

It has a lower viscosity than that of bisphenol A, has excellent compatibility with other resins, and has mechanical and chemical properties. The resistance is also excellent, and there is no particular limitation on the type, and for example, it may be bisphenol F diglycidyl ether.

The plastic epoxy resin is an epoxy resin modified with at least one selected from rubber and dimer acid, and the dimer acid is not particularly limited, and examples thereof include maleic acid and phthalic acid.

The dispersant may be a polyester-based derivative, and the polyester-based derivative has excellent non-aggregation, fluidity, and storage stability, and thus has excellent advantages for use as the coating agent 450 in the present invention.

The antifoaming agent is useful for removing air bubbles, and may be polysiloxane having excellent defoaming power even in neutral and acid/alkali environments. When polysiloxane is mixed with an acrylic resin (acrylic resin in 45% solution), its defoaming ability can be improved. In the present invention, the polysiloxane may be used as a combination of dimethylpolysiloxane and organopolysiloxane.

The filler may include at least one selected from barium sulfate, titanium dioxide, and color pigments, and increases hiding power and produces vivid colors.

Titanium dioxide is made of anatase-type titanium dioxide having pores with a central pore diameter of 0.01 to 6 nm inside the particles, and has ultraviolet absorption and antibacterial effects as a coating agent 450 and a paint.

Viscosity control agent is used to control viscosity, improves storage stability, and prevents staining by uniform dispersion with a dispersant to form a uniform coating film. The viscosity modifier may be xylene. In the present invention, 4.5 to 8 parts by weight of a viscosity modifier is added with respect to 100 parts by weight of the epoxy resin, and when it is out of the above range, a problem may occur, so that it can be used within the above range.

The rust preventive agent may be zinc orthophosphate, and in the existing method, the zinc primer is first applied, then the epoxy resin is applied secondly, and finally urethane is applied to finish the finishing work, but the present invention contains zinc orthophosphate, so the primer is first applied. After that, it can be finished by applying the coating agent 450 of the present invention.

Acley resin and light stabilizer are added to increase the stability of the resin and prevent discoloration by suppressing changes in physical properties due to photochemical reactions of certain substances or absorption of light.

The curing agent includes at least one selected from polyetheramine and silane compounds. Polyetheramine promotes curing and is a factor that determines the tensile strength and reaction rate of the formed coating film. In the present invention, the molecular weight is 230. If it is less than the above range, the tensile strength of the coating film is lowered, and if it exceeds the above range, tearing of the coating agent 450 is frequent, and cracks occur, so that a problem of lowering adhesion may occur. It is configured based on the above molecular weight. However, the user may change the molecular weight in some cases, and there is no limitation thereto.

The silane compound is used to improve insulation and flame retardancy of the coating agent 450 , and to reduce cracking due to excellent adhesion, and serves to accelerate curing as a curing accelerator. Silane compounds include methoxy silane, γ-glycidoxypropyl trimethoxysilane, γ-glycidoxypropyl triethoxysilane, γ-glycidoxypropylmethyl dimethoxysilane, γ-(3,4-epoxycyclohexyl) ) may include at least one selected from ethyl triethoxysilane, 3-aminopropyl trimethoxysilane, and 3-aminopropyl triethoxysilane.

The bamboo extract consists of at least one selected from bamboo powder and bamboo vinegar, and the bamboo extract can decompose harmful substances such as phenol and heavy metals. In addition to this, since it is possible to prevent the adhesion or penetration of marine organisms, it can act as a coating agent 450 or a paint containing an eco-friendly material.

6 is a flowchart illustrating a method in which a coating agent including an eco-friendly material is applied to a smart buoy to prevent attachment of marine organisms according to an embodiment of the present invention.

The surface is treated by removing contaminants from the adherend (S610).

That is, in the first coating agent application process (S630), one or more epoxy resins selected from a bisphenol A-based epoxy resin, a bisphenol F-based epoxy resin, and a plastic epoxy resin are synthesized and used with a silica resin to improve rust prevention.

The coating agent 450 of the present invention is applied secondarily to the first applied surface (S640).

The coating agent 450 used in the secondary coating process 640 is 100 parts by weight of a silica resin, 0.09 to 0.05 parts by weight of a dispersant, 6.8 to 10 parts by weight of an antifoaming agent, 13.5 to 32 parts by weight of a filler based on 100 parts by weight of a bisphenol F-based epoxy resin. Contains parts by weight, 4.5 to 8 parts by weight of viscosity modifier, 10 to 16 parts by weight of rust inhibitor, 52 to 55 parts by weight of acrylic resin and 4.5 to 8 parts by weight of light stabilizer, 10 to 100 parts by weight of curing agent, and 1 to 10 parts by weight of bamboo extract . That is, in the secondary coating agent application process (S640), the bisphenol F-based epoxy resin is synthesized with a silica resin and used, thereby improving corrosion resistance and preventing adhesion of marine organisms.

The coating agent secondary application process (S640) is a corrosion resistance and marine object adhesion prevention process. After the coating agent primary application process (S630), it may be preferable to perform the secondary coating agent application process (S640) within 12 to 24 hours. At this time, if the time is less than 12 hours, the epoxy does not harden and may melt, which is undesirable. Not desirable.

In the coating agent application method including an eco-friendly material to prevent adhesion of marine organisms according to the present invention, each coating thickness applied in the first and second coating agent application processes may be 100 to 200 μm.

As described above, in the present invention, the coating agent application method including an eco-friendly material to prevent adhesion of marine organisms synthesizes an organic epoxy resin and an inorganic silica resin, so the existing urethane resin coating operation can be excluded. In addition, by applying the coating agent 450 containing the bamboo extract having an effect of preventing the adhesion of marine organisms to the surface of the smart buoy 100, it is possible to prevent corrosion of the smart buoy 100 surface, increase durability, and prevent the adhesion of marine organisms.
