Description

TECHNICAL FIELD [0001] The present invention relates to a real-time spatial image-capturing device, and more particularly,

More particularly, the present invention relates to an image display and synthesis system for displaying an image of a feature in a space image display technology, and more particularly, it is possible to efficiently operate a camera by reducing a space for mounting a digital camera, The user can effectively sense the realism of the digital map, and a plurality of modules and DBs constituting the photographing unit and the output unit can be stably maintained And more particularly, to an image display synthesis system for displaying an image image of a feature including a housing having a cooling function so as to prevent deterioration due to heat generation.

Digital video images are widely used as the background of digital map without any painting work. This is because the digital map based on the due diligence is advantageous for user's map interpretation and location confirmation.

On the other hand, in order to secure the image, the ground is directly photographed from the aircraft. Accordingly, the image of the ground structure installed on the ground according to the photographing position of the aircraft is variously changed as shown in FIG. 1 (an image showing the appearance of the ground structure according to the aerial photographing position). For reference, FIG. 1 shows how the same building (indicated by orange color) is expressed according to the photographing position in nine rows and three columns.

A conventional digital map using a video image as a background applies a video image applied to the background as if the ground structure is as flat as possible.

Therefore, even though the user views the digital map to view the digital map and then moves the output image to check the digital map, the ground structure included in the image is always displayed in the same plane.

That is, even if the ground structure moves to the right side of the monitor by moving the corresponding image image to the right while the specific ground structure is positioned at the center of the monitor, the flat image in the center position of the monitor is outputted.

For reference, when you see the ground directly on the aircraft, you can see the plane as well as the side of the specific ground structure depending on the position of the aircraft.

Of course, applying a flat image image as a background of a digital map minimizes the visual interference between the ground structure and the road, the ground structure and the ground structure, so that the positional relationship between the road and the ground structure can be clearly identified , Which is also advantageous for the user to find a route using the digital map.

However, from the viewpoint of the user who uses the digital map on the ground, it is difficult to match the ground structure which can not normally see the plane (roof) with the digital map, and there are many cases in which the correction This means that it takes a considerable amount of time to understand the numerical map, and an improvement measure is required.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The present invention uses the above-mentioned prior-art patent No. 0947106 as it is. Therefore, the features of the device configuration described below are all described in Patent Registration No. 0947106. [

However, the present invention is characterized in that the improvement in the rotation radius of the digital camera among the configurations disclosed in the above-mentioned Japanese Patent No. 0947106 is the most important constitutional feature.

Therefore, the device structure, characteristic and operation relationship described below will be incorporated by reference in the above-mentioned Japanese Patent No. 0947106, and the structure related to the main features of the present invention will be described in detail at the rear end.

First, as shown in FIG. 1 to FIG. 4, the data processing in the present invention allows a user to feel an image output to a monitor as if he or she is looking directly at an aircraft, The user who uses the digital map can feel the reality and can confirm various aspects of the ground water B so that the user can easily match the ground on which he is located and the digital map.

This is achieved by acquiring a plurality of image images used as the background of the digital map and providing a desired image according to a user's selection. Since the provision of the images is performed on a uniform basis according to a certain condition, You can see the image in realistic way from the desired direction.

In order to secure a video image to be applied to the present invention, a photographing module 110 that rotates in the traveling direction of the aircraft A is required as shown in FIG.

At this time, the photographing module 110 rotates by driving the wide angle rotation module 120 while a plurality of digital cameras 113 are rotatably fixed to the rotation axis 111 via the rotating body 112. Of course, all of the plurality of digital cameras 113 are located at a certain distance about the rotation axis 111.

Subsequently, a plurality of digital cameras 113 are simultaneously photographed.

Therefore, as shown in Figs. 2A to 2C, the digital camera 113, which is facing the ground regardless of where the aircraft A is located with respect to the ground B, continues to shoot the ground .

For reference, since the plurality of digital cameras 113 are arranged in a circular shape along the rotating body 112, a digital camera aimed at the ground as well as a digital camera aiming at the opposite direction of the ground exist at the same time. Therefore, all of the digital cameras 113 constituting the photographing module 110 may simultaneously perform the photographing operation, and in consideration of the efficiency, only the digital camera aiming at the ground may proceed the photographing operation at the same time.

On the other hand, the digital camera 113 determines the shooting time according to the flight information such as the speed and altitude of the aircraft A, and the rotational speed of the rotating body 112 is also determined according to the flight information.

2 and 3, the aircraft A proceeding with the aerial photographing moves in a linear direction over the point of the image image to be photographed. At this time, the operation mode of the photographing module 110 is changed according to the flight information of the aircraft A so that the digital camera 113 can continuously photograph the specific point. This is also described in detail below.

The image processing system according to the present invention includes an image pickup unit 100 mounted on an aircraft A for photographing the ground, an output unit for outputting and utilizing a digital map with a background image of the image picked up by the photographing unit 100 200).

The photographing unit 100 includes the above-described photographing module 110, a wide angle rotation module 120 for determining and rotating the rotation speed of the rotating body 112 according to the operation information, A speed detection module 140 for checking the moving speed of the aircraft A and transmitting the detected speed to the wide angle rotation module 120; A coordinate formation module 160 for confirming GPS coordinate information on a photographing point of a video image and linking to a corresponding file, a file creation module 150 for creating a video image, And a storage module 170 for storing the image information file and coordinate information confirmed by the coordinate confirmation module 160 and linked. Here, the storage module 170 may be a publicly known storage medium such as a hard disk, a floppy disk, a CD, or a USB memory.

The output unit 200 includes a ground structure image confirmation module 210 for classifying only the image of the ground structure by checking the image stored in the storage module 170 and an image editing unit 210 for separating the ground structure image A data storage module 230 for storing the final result of the edited video image through the image editing module 220, and an image editing module 220 for outputting the image image through the monitor, An output module 240 for searching and outputting an image, and a link information DB 250 for storing related link information of the ground structure image among the final images of the image.

FIG. 6 is a view for explaining the operation of the wide angle rotation module according to the present invention, The image which shows the image of the ground structure image is explained with reference to this.

S11; Flight information verification step

The speed sensing module 130 and the altitude checking module 140 configured in the photographing unit 100 of the aircraft A confirm the flight information of the aircraft A. [ Here, the flight information includes the speed and altitude information of the aircraft A, and is connected to the board of the aircraft A in a communicative manner so that the speed and the altitude information can be provided thereto, You can also measure and detect information and collect it. The structure and structure of the speed sensing module 130 for measuring the speed of the aircraft A and the structure and structure of the altitude verifying module 140 for measuring the altitude of the aircraft A are generally well known and common technologies The description of the circuit characteristics and the mechanical structure of the speed sensing module 130 and the altitude checking module 140 will be omitted.

S12; Rotation speed calculation step

The wide angle rotation module 140 checks flight information collected by the speed detection module 130 and the altitude confirmation module 140, and controls the operation of the photographing module 110 based on the information.

More specifically, a plurality of digital cameras 113 radially arranged in a rotating body 112 rotatably fixed about a rotating shaft 111 rotates the rotating speed of the digital camera 113 based on the flying information of the aircraft A, And the photographing period of the digital camera 113 are determined. That is, as described above, in order for the digital camera 113 to take a picture at a specific point on the ground so that continuous shooting can be performed even while the aircraft A is moving, the rotational speed of the rotating body 112 is lower than the rotational speed of the aircraft A Speed and altitude information of the vehicle.

As shown in FIG. 6, for the ground photographing, the altitude and the speed of the aircraft A must be kept constant. In this premise, 'h', which is the altitude of the aircraft A, becomes the radius of the virtual circumference C, and when the aircraft A goes straight at a certain height, the imaginary circumference C is like the wheel of the aircraft A Shape. Therefore, when the arbitrary digital camera 113 photographs the point P1 and the aircraft A moves in the left direction in the state that the aircraft A is positioned in the upper right room of the point "P1" In order to allow another digital camera neighboring the arbitrary digital camera 113 to photograph the point P2 in a state of being located in the room, a straight line distance between the point P1 and the point P2 is set so as to correspond to the point P1 and the point P3 And the linear velocity of the aircraft (A) passing through the points P1 and P2 and the angular velocity with respect to the inner angle of 'θ' of the point P1 and the point P3 should be matched.

Through this condition, the wide angle rotation module 120 calculates the rotation speed of the rotating body 112 and rotates the rotation axis 111 at the calculated rotation speed.

The wide angle rotation module 120 may calculate and process the rotation speed of the rotating body 112 according to the current altitude and the speed of the aircraft A, The altitude and speed of the aircraft (A) may be adjusted accordingly.

S13; Ground shooting steps

A plurality of digital cameras 113 radially arranged along the circumference of the rotating body 112 photographs the ground at regular intervals according to a constant rotation speed of the rotating body 112. Of course, all of the digital cameras 113 installed in the rotating body 112 can simultaneously perform photographing, and only the digital camera 113 aiming at the ground may change the design so that the photographing is performed.

On the other hand, the photographing time point of the digital camera 113 may be when the digital camera 113 correctly targets the P1 or P2 point on the ground in the vertical direction in the room immediately above P1 or P2 as shown in Fig. Therefore, the greater the number of digital cameras 113 arranged at regular intervals around the circumference of the rotating body 112, the shorter the photographing period of the digital camera 113 will be.

For reference, the photographing period of the digital camera 113 is set by the wide angle rotation module 120. That is, the wide angle rotation module 120 calculates and determines the rotation speed of the rotating body 112, and sets the photographing period of the digital camera 113 in accordance with the determined rotation speed.

S14; Steps to check the shooting location

The coordinate confirming module 160 confirms the photographing time point of the digital camera 113 and measures GPS coordinates for the position. That is, when the digital camera 113 operates for photographing, the coordinate confirmation module 160 measures and records the current position.

The coordinate confirmation module 160 for measuring the GPS coordinates may be applied to a conventional GPS measuring device.

S15; Image data storage step

The file forming module 150 links the GPS coordinates measured by the coordinate checking module 160 to the file to store the captured image in a file form in the storage module 170, When searching for a file, the linked GPS coordinates are also searched and confirmed.

S16; Ground Structure Image Identification Step

The ground structure image verification module 210 analyzes the file stored in the storage module 170 and searches for an image of the ground structure included in the image data of the file.

As is well known, a color monitor for outputting an image outputs various types of images that can be identified by assigning colors to pixels arranged densely on the monitor surface. A user viewing the color monitor can select a color Identify images by checking the same specified colors repeatedly and consecutively within the range.

The ground structure image checking module 210 uses this principle. It checks each pixel of a monitor on which a video image is output, searches for pixels arranged in the same or similar color so as to have continuity, Thereby forming a boundary line. Here, the continuity means that pixels designated by the same, similar color are immediately adjacent to each other, and pixels designated by the same, similar color are within a predetermined interval. That is, if pixels designated by the same or similar color are arranged in a line within a certain interval, they are connected to form a boundary line.

On the other hand, if the boundary lines formed in this way are connected in a line to form a closed boundary of one or both ends without forming a closed boundary, the boundary line is regarded as not the boundary of the image of the ground structure.

For reference, since the building is constructed of the same aggregate, the image of the ground structure photographed from the building will be clearly divided into the same color, and the boundary line will be formed along the frame.

S17; Image image editing step

When the image of the ground structure is confirmed by the ground structure image confirmation module 210, the image editing module 220 separately separates the ground structure image as shown in FIG. 7, and synthesizes the image of the ground structure in a separate layer format.

Therefore, the output module 240 can distinguish the ground structure image when outputting a video image, thereby outputting the video image being output to the monitor. The description will be described in detail below.

S18; Edit data storage step

The image image having a plurality of ground structure images independent of the layer format is stored in the data storage module 230.

Meanwhile, the image editing module 220 links the related link information to the image of the ground structure when storing the image image, and stores the link information in the data storage module 230. At this time, the link information is stored in the link information DB 250 and may be data such as the name, location, size, usage, etc. of the corresponding ground structure.

When the link information is linked to the image of the ground structure, the image output means 244 of the output module searches the link information DB 250 for the link information of the image of the ground structure included in the image image, When the user selects the image of the ground structure in the layer format, the image output means 244 recognizes it and outputs the window in which the link information is posted.

For reference, the link information stored in the link information DB 250 may be updated and changed in real time when the content is changed, and the ground structure image independent of the background of the image image may be adjusted and updated after the image change.

FIG. 8 is a flowchart sequentially showing a data processing method according to the present invention. FIG. 9 is a view showing an image of a ground structure photographed by the aerial photographing method according to the present invention, and will be described with reference to FIG.

S21; Digital Map Call Step

In order to use the digital map, the user inputs the keyword for the specific region into the image search means 243 of the output module 240. [ Here, the keyword may be a common word input for searching a map, such as an administrative area name such as an address, a name of a shop or a shopping mall.

For reference, the output module 240 according to the present invention can be manufactured as an independent device together with the data storage module 230, and the manufactured device can be utilized as an apparatus such as a navigation system, And may be used as a server of a map search service.

S22; Image Image Search Step

The image search means 243 searches the data storage module 230 for the associated aerial image based on the keyword.

Meanwhile, the data storage module 230 simultaneously searches for a plurality of image images within a certain range based on a corresponding point of the keyword when searching for a keyword-related image. In other words, in a state in which a point directly related to the keyword is displayed so as to be located at the center 11 of the monitor screen even in a searched image image related to the keyword, 9 (b), it is necessary to search for the neighboring image that is output when it is down. Of course, the neighboring video image at this time should be a ground state viewed from the center 11 of FIG. 9 (a) as viewed from the center 11 of FIG. 9 (b) It should be.

For reference, the retrieved image image may be set with reference points 12, 12 ', 12 "for confirming the output of the image image and its movement. The reference points 12, 12', 12" It may be a separated ground structure image or a setting value different from the ground structure image.

The description will be described below.

S23; Image image output step

The image image retrieved by the image retrieval means 243 is output to the monitor screen as shown in Fig. 9 through the image output means 244. [

S24; Image moving step

The user can move the image image for the purpose of confirming other neighboring points in addition to the image image being output to the monitor. For reference, FIG. 9 is a view sequentially showing a state in which a video image is moved downward. At this time, the movement of the image may be performed by a conventional means through manipulation of a mouse or a keyboard. The movement of the video image according to the present invention is the same as the normal movement method of the image being output to the computer. When moving the image, the reference points 12, 12 ', 12 " We will move together.

S25; Ground Structure Locations Step

The image identification means 241 identifies the image of the ground structure designated in the form of an independent layer and the image tracking means 242 identifies the position of the ground structure image or reference point 12, 12 ', 12 " ≪ / RTI >

Generally, since the output position is determined by the OS that controls the operation of the computer, the image outputted to the monitor is checked for information about the image output controlled by the OS, so that the image of the ground structure in the layer format is output It will be able to confirm whether it is.

S26; Output image replacement output step

The image output means 244 divides the monitor into a plurality of spaces to set the boundaries 20 and the tracking of the image tracking means 242 causes the boundaries 20 to be moved, And outputs the linked neighboring image.

As described above, the image retrieval unit 243 searches the data storage module 230 for a plurality of image images including neighboring image images, and each of the image images is linked to the boundary unit 20 partitioning the monitors, When the image of the ground structure is moved to another boundary, the neighboring image image linked to the boundary is immediately output. That is, the image search means 243 associates the ground structure image or reference points 12, 12 ', 12 "and the center 11 of a plurality of video images searched by the image search means 243, And outputs the image image in which the image of the ground structure is located.

For example, when the identification of the image is proceeded to the set reference points 12, 12 ', 12' ', the image retrieving unit 243 retrieves the corresponding image data from the data storage module 230 (12, 12 ', 12 ") in an image or a point of a ground structure (hereinafter referred to as a " ground structure image ") positioned at the center of the searched image image, 9 (a), the monitor outputting the image image is divided into two boundary portions (12, 12 ', 12' ') 20).

9 (b), if the reference point 12 of the image image output in FIG. 9 (a) moves away from the region where the center 11 is located, And outputs a neighboring image image having a reference point 12 'located in a region in which the center 11 of the monitor is neighboring in a line in the moving direction among the connected neighboring images.

9 (c), the reference point 12 'of FIG. 9 (b) is out of the center 11 of the monitor and, as described above, And a reference point 12 "located in the center 11 of the image.

For reference, in the embodiment shown in FIG. 9, the monitor is divided into three sections by the upper and lower rows. However, it is preferable to divide the monitor into a plurality of sections in order to output real image images. Alternatively, the range of the area where the center 11 is located may be narrowed to delicately track the inflow and outflow of the ground structure image or reference point 12, 12 ', 12 "within the above range.

Since the ground structure images in the independent layer format can be discriminated from each other, it is possible to replace the reference points 12, 12 ', 12 "with ground structure images without setting separate reference points 12, 12' Of course.

As a result, the user can see the image displayed on the monitor as if he / she is looking at the ground on the aircraft, so that the user can enjoy the fun of using the digital map and also can view the side view. It is possible to match figure and numerical map efficiently.

10 and 11, a plurality of modules including the DB configuring the photographing unit 100 and the output unit 200 are mounted on one housing 2130, and these DBs and modules A cooling function is included in the housing 2130 to prevent the lifetime of the housing 2130 from being shortened due to deterioration due to a heating problem and to shorten the maintenance period.

Particularly, there is a need for a special structure of the housing 2130 that can effectively suppress noise due to heat generation in addition to the heat generated by driving the modules.

In addition, since the modules mounted inside the housing 2130 are weak against heat, it is necessary to cool them in terms of prevention of deterioration. However, when the module is cooled by a simple direct air blowing type, dust inside the housing 2130 is scattered, Is high.

However, since the housing 2130 is provided inside the aircraft, it is better if it has a vibration damping structure, and the size can be sufficiently adjusted. At this time, the vibration damping structure will be described later.

Therefore, indirect cooling needs to be carried out effectively and effectively.

To this end, the present invention has the structure of the housing 2130 as shown in FIG.

10, the housing 2130 includes a rectangular frame 2132 and a front door 2134 is hinged to one side of the fixing frame 2132 so that the front door 2134 can be opened and closed. A rear plate 2136 is fixed to the rear surface of the front frame 2134 opposite to the front door 2134 and a side plate 2138 is fixed to both sides of the fixing frame 2132, And an upper plate 2142 is fixed to a ceiling facing the bottom plate 2140. [

In addition, air suction holes 2138a in the form of a rectangular slit are formed in both side plates 2138, and a filter 2138b is incorporated in the air suction holes 2138a.

Therefore, the outside air is introduced into the housing 2130 in a filtered state.

Meanwhile, an indirect cooling unit 2150 is installed on the upper surface of the upper plate 2142.

11, the indirect cooling unit 2150 includes a rectangular box-shaped suction chamber 2152 opened to communicate with the housing 2130 through the upper plate 2142, A blowing pipe 2154 penetrating through the center of the top surface of the suction chamber 2152 and having a hooked lower end inserted and fixed therein, a blowing fan 2156 installed at the upper end of the blowing pipe 2154, An exhaust hole 2160 formed in the horizontal portion 2158 and a plurality of exhaust ports 2162 formed in the upper surface of the rear chamber 2152 on a position equivalent to the exhaust hole 2160.

Therefore, when the blowing fan 2156 is operated, the outside air is introduced and discharged into the blowing pipe 2154, and then discharged through the discharge hole 2160 and the discharge port 2162.

That is, the introduced outside air is not supplied into the housing 2130 but is diverted and then discharged to the outside.

In the process, negative pressure is generated in the interior of the suction chamber 2152, particularly around the discharge port 2162, and the internal air distributed in the lower space of the suction chamber 2152 due to a kind of venturi effect due to the suction pressure by the negative pressure So that the heated air inside the housing 2130 is sucked to the outside.

As a result, the inside of the housing 2130 is entirely formed with negative pressure, fresh cool external air is introduced into the housing 2130 through the suction hole 2138a via the filter 2138b, dust is generated in the housing 2130 It is naturally cooled to a non-scattered state.

That is, since the general cooling structure is a structure in which outside air is introduced through the air blowing fan 2156 and is directly injected into the housing 2130 to be cooled directly, severe dust is generated inside the housing 2130 due to wind pressure , The dust is attached to the main terminals of each module, and in some cases, a spark due to static electricity is generated and a short circuit is caused.

However, since the present invention has an indirect blowing mode in which such a situation is completely dispensed, that is, an indirect cooling structure, cooling can be performed without generating dust inside the housing 2130.

The inner surface of the front door 2134, the side plate 2138, the bottom plate 2140 and the thick plate 2136 constituting the housing 2130 is formed with a heat-resistant coating layer and a latent heat-resistant coating layer. If the latent heat function, that is, the heat retaining function, which expels the heat in the cold state, is provided, it is possible to operate more stably and thus deterioration of the board can be suppressed as much as possible. In addition, it is more preferable to provide an antistatic function, a moisture resistance, an antifouling property, and a fire resistance so as to contribute to stabilization to prevent a short circuit.

The coating layer for this purpose was a polystyrene resin and 3.5 parts by weight of pozzolan, 2.5 parts by weight of urushiol, 10 parts by weight of low toxicity flame retardant, 3.5 parts by weight of hydroxypropylcellulose, 2 parts by weight of alkyltrialkoxysilane 1.5 parts by weight of 1,4-butylene glycol, 8 parts by weight of sodium silicate, 2.5 parts by weight of oxycarboxylate, 1.5 parts by weight of citronella oil, 3 parts by weight of microencapsulated polypropylene yarn , 5 parts by weight of paraffin wax, 4 parts by weight of polyoxyethylene, 3 parts by weight of propylene glycol, 2.5 parts by weight of N-ethylgavazol methacrylate, 3 parts by weight of sepiolite, 2.5 parts by weight of melamine cyanate, 2.5 parts by weight of nate and 1.5 parts by weight of mica, and spray-coating the mixture at 50-60 캜.

Here, the reason why the mixture is heated to the above-mentioned temperature range is to maintain uniform dispersibility and stability while increasing fluidity, and the polystyrene resin is a typical refractory resin, and is a base resin for impact resistance, heat resistance, weather resistance, Pozzolan is mainly used as concrete admixture, but it is an artificial pozzolan. In the present invention, in order to increase acid resistance, corrosion resistance, durability and waterproof property, natural pozzolan collected from volcanic ash and volcanic rocks And the particle size is preferably 0.1-0.2 mm. However, if it is encountered with water, it will cure quickly and easily.

In addition, the above urushiol (Urushiol) is a phenol derivative, a natural moisture-proofing agent, and is a representative lipophilic compound structurally similar to tocopherol, which is a natural antioxidant. In the present invention, a mixed solution of 40% by weight of urushiol and 60% by weight of rubber is used to increase the corrosion resistance. At this time, the rubber contributes to increase the flexibility.

In order to meet the requirements of ROHS and IEC 61249-2-21 for the use of non-halogen flame retardants, the low toxic flame retardant is excluded from the halogen-based flame retardant, and the content of phosphorus is maintained in the range of 400-1500 ppm while maintaining the bromine content below 900 ppm Based flame retardant.

In addition, the hydroxypropyl cellulose is added in order to enhance the durability by enhancing the adhesion strength by increasing the adhesive strength. The alkyltrialkoxysilane improves not only the water repellency but also the oil repellency to increase the surface slip property, And the 1,4-butylene glycol is added in order to enhance adhesion and maximize adhesion.

In addition, the sodium silicates are added to enhance the heat stability by inducing gelation to form a film.

In addition, the oxycarboxylate is added to reduce moisture content of the material to reduce voids and thereby increase strength.

The citronella oil is generally added to improve the insect repellency, but in the present invention, it is added in order to promote the viscosity control and the coordination of the inorganic powders.

In addition, a polypropylene yarn having a length of 0.1 mu m and microencapsulated by a Wurster Method can be further added so that heat resistance can be realized in the urethane resin.

The paraffin wax is a phase change material having a phase change temperature range of 20 to 50 ° C. The paraffin wax is a phase change material which accumulates latent heat during heating to prevent the temperature from being deprived, thereby performing a heat holding function for a long time, So that it is added in the present invention for latent heat utilization.

Polyoxyethylene is a kind of polyether which is obtained by polymerization of ethylene oxide with a cationic catalyst. In the present invention, it is added in order to inhibit the generation of static electricity by forming a film in a state of being dissolved in water in a fabric and paper.

In addition, propylene glycol is hygroscopic but has no volatility and is stable to heat and light, so it is used as a solvent to dissolve resin and mix with water, and is added to prevent fungal growth on the surface.

In addition, N-ethyl-carbazole methacrylate is added to prevent cracking by inducing stabilization of the coating layer while enhancing transparency.

Furthermore, sepiolite is referred to as meerschaum, a round tubular variant, and is added to induce dispersion stability and uniform dispersion of the resin composition.

In addition, melamine cyanate is added to reinforce heat resistance. Tetraisopropyltitanate is a coupling agent having an organic titanate structure, which enhances the interfacial adhesion between the polymer resin and the inorganic substance to increase both durability and heat resistance And mica is a kind of silicate minerals which are crushed to a size of 0.1-0.2 μm and sieved and added to enhance surface hardness and heat resistance due to hardness characteristics.

The structure of the coating layer contributes to prevention of deterioration of the module using heat resistance and latent heat characteristics.

In order to confirm whether or not the coating layer has latent heat characteristics, that is, heat retainability, a steel plate sample having no coating layer and a steel plate sample having a coating layer were prepared, and heat radiation side was confirmed according to JIS C 6802-1997.

As a result of the measurement, it was confirmed that there was a latent heat characteristic (heat absorption power) when the coating layer was present at 46 W / m.k when there was a coating layer and 58 W / m.k when there was no coating layer.

Further, as shown in FIG. 12, a plurality of radiating fins 2170 are further formed to pass through the inner coating surface of the front door 2134 and the side plate 2138 to further enhance the heat radiation characteristic.

That is, the radiating fin 2170 is first formed, and the coating liquid is sprayed to form a coating layer.

At this time, the radiating fins 2170 should protrude more than the surface of the coating layer, thereby increasing the heat radiating effect.

The front door 2134 and the side plate 2138 are formed to have a hollow portion 2172 therein and on the outer surfaces of the front door 2134 and the side plate 2138, It is further preferable that an opening 2174 communicating with the hollow portion 2172 is further formed so that the heat transferred to the hollow portion 2172 can be quickly discharged to the atmosphere.

In this case, it is preferable that the outside of the hollow portion 2172 is entirely opened to reduce the thickness thereof, but this is particularly preferable because it is related to the appearance quality.

In addition, the housing 2130 may be attached to the sound absorbing sheet 2180 along the inner surface of the side plate 2138, as shown in FIG. 13, to reduce noise generated during operation of the devices mounted therein.

The sound absorbing sheet 2180 is in the form of a gasket and is mounted on the coating layer and along the circumference of the side where the heat radiation fins 2170 are not formed so as not to interfere with the heat radiation fins 2170.

Particularly, the sound absorbing sheet 2180 is not a known non-woven fabric but uses a circular knitted fabric to significantly increase sound absorption and sound insulation effects.

That is, when the yarn is circularly wound through the circular knitting machine, a substantially cylindrical fabric is formed. The material of the fabric is polypropylene yarn, and at least a, b, c, , and c two knitting yarns are knitted into a general fabric, and b and d two knitting yarns are knitted into a denser elastic structure so that the circularly formed polypropylene knitted fabric 2182 is repeatedly formed in a longitudinal direction and compacted, So that the sound absorbing characteristic is improved by making the sound absorbed, i.e., sounding, completely obstructed.

In addition, in order to improve sound absorption characteristics and adhesion properties, the cylindrical polypropylene knitted fabric 2182 is flattened in a radial direction to form a double layer, and the outer surface, that is, the periphery of the double- So that the sound absorbing sheet 2180 according to the present invention can be realized.

In this case, since the cylindrical polypropylene knitted fabric 2182 can not be inflated in a pressed state, it is possible to safely hold the sheet image. In particular, the PET film 2184 is needle-punched for forming voids, Structure.

Then, the generated noise is introduced into the polypropylene knitted fabric 2182 through the needle hole of the PET film 2184, is completely confined, is refracted and reflected inside, loses energy, and is completely cased, and the sound is lost. .

In addition, as shown in FIG. 14, a thin box-shaped explosive housing 3000 may be further provided on the inner surfaces of both sides of the side plate 130 to scatter the built-in refractory material when the temperature condition is reached.

The explosion housing 3000 is formed in a box shape in a state where 80% by weight of polyurethane resin and 20% by weight of silica are mixed and one side is opened to a predetermined size to form an opening 3100. The opening 3100 A mesh network 3300 is attached.

Accordingly, since the plastic bag 3200 with the refractory material embedded therein is enclosed by the net 3300 in a state of being loaded in the explosion housing 3000, the plastic bag 3200 is kept in a fixed state without being detached, The plastic bag 3200 and the net 3300 are torn and the refractory liquid is scattered to extinguish the fire.

Particularly, since the explosion housing 3000 has no explosive force of its own, an explosion sheet 3400 may be installed in front of the net 3300 in order to facilitate the explosion.

The explosion sheet 3400 is a state in which a first sheet to which potassium chlorate is attached and a second sheet to which the (red) is attached is attached with a thin paper therebetween. When heat is generated during a fire, So that the plastic bag 3200 containing the refractory material reacts to the explosion and scattered.

At this time, since potassium chlorate is water-soluble, it is preferably coated in a form of being sprayed on the first sheet by dissolving in water, and since the silver is insoluble, the powder is sprayed and solidified before the second sheet is solidified And the first and second sheets are all preferably made of a polyurethane resin in a sheet form.

The refractory material is a refractory foamed material that is installed in a granular pipe of an apartment or the like, and is a known material that explodes when it is heated to 300-400 times its size.

However, it may further include clay powder to enhance fire resistance.

11, the positive electrode E1 and the negative electrode E2 are arranged at regular intervals below the blowing fan 2156 to generate plasma due to discharge while power is being supplied when the blowing fan 2156 is driven The air cleaning effect can be obtained.

At this time, the positive electrode E1 and the negative electrode E2 are preferably laminated in a plurality of layers with a small spacing in a lattice form in order to increase the discharge efficiency.

11, a guide rod GR is further provided at the lower end apex of the blowing tube 2154, that is, a pointed portion, and a cylindrical guide flap WIG, which is opened downwardly, is inserted into the guide rod GR When the cap is closed by the cap (CAP), a space below the blowing pipe 2154 is partially occupied to reduce the space, thereby reducing the flow area of the sucked air and sucking it easily.

In this case, the guide flap WIG moves up and down on the guide rod GR when air is caused to flow by the suction pressure.

In particular, the housing 2130 according to the present invention is preferable to include a structure that minimizes flow or vibration due to its being installed in an aircraft.

To this end, the present invention further includes support legs 4100 on the bottom surface of the lower plate 2140 as shown in FIG.

At this time, the support leg 4100 is fixed to the upper end of the fixing table 4200 with a spring groove 4300 formed therein, a spring 4400 is embedded in the spring groove 4300, A lower end of the leg rod 4500 is seated on the upper end of the spring 4400. A lower end portion of the leg rod 4500 is passed through the upper end of the fixing rod 4200 in a state of being hooked on the spring groove 4300, And screwed to the lower end of the lower plate 2140.

That is, the spring groove 4300 and the upper end surface of the fixing table 4200 are communicated with each other. The diameter of the communicating path PA communicating therewith is smaller than the diameter of the spring groove 4300, Is formed with a diameter corresponding to the spring groove 4300 larger than the diameter of the communication path PA.

Therefore, the lower end of the leg rod 4500 is caught by the lower end of the communication path PA, so that it can not escape any more.

At this time, the assembling process is such that the upper end of the leg rod 4500 is first inserted through the lower side of the spring groove 4300 before the fixing table 4200 is assembled to the supporting leg 4100, the communication passage PA is passed therethrough, The upper end of the rod 4500 is screwed to the lower end of the fixed unit 200.

Then, when the support leg 4100 is fastened to the lower end of the fixing table 4200 after inserting the spring 4400, it can be easily installed.

When the spring 4400 is fixed in this manner, the elastic force of the spring 4400 absorbs the fluid force to enable stable installation.
