Description

3D high precision digital mapping system{3D high precision digital mapping system}

The present invention relates to a three-dimensional high-precision digital map production system in the field of digital map technology, and more specifically, a point inconsistent by precisely comparing the ground image represented by the polygon object type in the digital map with the actual topographic image located at the corresponding point. Improved to efficiently and indirectly cool the enclosure in which the modules are mounted so as to control the numerical coordinates of the corresponding point or to adjust the image of the ground to the numerical coordinate position while suppressing the deterioration of the modules necessary for the digital map processing. Dimensional high-precision digital map production system.

In general, in order to express the groundwater image expressed on the digital map as a geometric element, the drawing elements of points, lines, and faces are used.

Specifically, looking at the case of expressing as a face on a digital map, various topographic features such as a road boundary surface, a building, a silpok river, and a water surface boundary surface are expressed as a surface and displayed in colors and patterns.

That is, in most cases, one terrain object is represented by one plane object, but two or more plane objects are formed to express one terrain object.

Currently, most systems that edit or manage digital maps express faces as polygon objects. If another face exists inside the face, the inner face object is called a hole.

In addition, multiple polygons are formed to form an object, which is called a multipolygon.

At this time, in the case of expressing the color of the polygon, the hole does not display the color. That is, it shows a perforated surface shape.

When performing input and editing operations for the creation of a digital map (DWG file) using the above-described method, polygons and multi-polygons can be expressed only with closed-polylines connected at both ends.

At this time, the polygon object and the multi-polygon object do not exist. For example, in the case of expressing a polygon having one hole, another closed polyline is displayed in the area inside the closed polyline, and the multi-polygon having two faces can be expressed by separating into individual closed polylines.

However, since a single terrain feature can be represented by multiple objects, it requires a lot of attention by the operator by entering and editing a digital map or by considering other related objects together when searching for a certain geographical feature in a digital map. And the efficiency of the work decreases.

In addition, in the case of a hole polygon, the entire hole should not be filled when displaying the color, but the inside hole should be displayed so that a hole is formed.

However, in the conventional hole display method, two closed polylines, that is, the outer polyline and the inner polyline overlap, so that the inner polyline (hole) is covered, or the two polylines are respectively selected, so that one hole is perforated. It cannot be expressed as an object.

Also, when importing or exporting data formats of other systems that support polygons or multiple polygons, additional work is required to maintain the object type.

That is, there is a problem in that the information of the separated object must be separately managed when importing, and the separated object in the system of the stored file must be edited again as one object when performing export.

On the other hand, the digital map can be checked using the Autocad system. Polygon and multi-polygon objects exist when using the higher version of the CAD system. However, in the case of using the Autocad system, files created in the higher version are saved in the lower version. There is a problem in compatibility because it cannot be checked.

In addition, although an object type can be newly created and used by developing another application, if an object created through another application is stored as a file, there is a problem that editing and modification are impossible without an application program accordingly.

Accordingly, a patented technology for a multi-polygon generation system and method using the attribute information of a numerical map object that allows identification of polygons based on this by inputting unique attribute information such as numerical coordinates for each polygon has been disclosed. have.

However, this technique has a trouble and difficulty in the work because the operator must input the corresponding attribute information for each polygon according to the established rule.

To explain this in more detail, conventionally, in a numerical map in which areas or objects are divided in units of polygons, an operator may use multiple polygons in which a plurality of polygons constitute one object, and polygons in which one polygon constitutes one object. It is to directly classify and input the numerical coordinates of the corresponding point as attribute information to each of the divided polygons, or to input the unique code of which the numerical coordinates are linked as attribute information.

However, in this method of inputting attribute information, the burden of work was high because the operator had to manually input the attribute information for numerous polygons. Moreover, the burden of time was also high because the attribute information had to be checked and input for each polygon individually. There is a problem in that incorrect attribute information may be input to an arbitrary polygon due to a mistake or mistake.

Moreover, this manual method has a problem that it is difficult to produce a precise digital map by causing a positional mismatch between the actual topographic image of the aerial photographed point (the aerial photographic image) and the corresponding ground image in the digital map.

In addition, the prior art, which is performed manually, has a problem in that the object structure of polygons has to be limitedly used in a simple numerical map.

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

As illustrated in FIG. 1, the system according to the present invention performs a function of giving certain attribute information to a polyline belonging to a polygon, and receives a digital map produced using a digital map production software (A) from an operator. The receiving data input module unit 10, and a generating module unit 20 for generating an MP polygon object by analyzing a geometrical relationship of a polyline constructed in the polygon by selecting an operator from a numerical map of the polygon object, The attribute information setting module unit 30 for setting the value of the attribute information linked to the polyline, the attribute information attachment module unit 40 for linking the set attribute information to the polyline, and the empolygon existing in the digital map ( The search extraction module unit 50 for searching MPolygon), the change module unit 60 for removing attribute information linked to a polyline in a numeric map or maintaining the link state, and an MPolygon object as a list A database module unit 70 that registers and manages, and a display module unit that displays the extracted polygon through the search extraction module unit 50 using a screen or an output device provided separately so that an operator can check the extracted polygon. (80), the object comparison module unit 100 that compares the completed digital map and the targeted terrain image with each other, such as an object type, such as an MPolygon object, a polygon object, and a polyline object. The object modification module unit 110 for correcting an object having a difference in accordance with the terrain image, and the components 10, 20, and 30 according to the procedure of the operating program to search, create, and edit polygons on the digital map , 40, 50, 60, 70, 80, 100, 110).

In this embodiment, the process of processing the digital map is performed by the digital map production software (A), and the description will be omitted below, but the series of production methods disclosed in the present invention is a part of the digital map production software (A). It is desirable to understand that features are included.

That is, it can be confirmed by receiving the digital map stored in the DWG file and using Autocad.

Here, although the digital map production software (A) is set to autocad, the present invention is not limited thereto.

When the generation module unit 20 selects a polyline on the numerical map using the object selection module 21, the confirmation analysis module 22 determines whether the polyline is closed or not and whether a shared polyline exists between polygons. After analyzing the geometric relationship in consideration of the intersection of the polylines or the existence of an independent polyline in the polyline, one polygon or multiple polygons as shown in FIG. 2A through the object creation module 23. (MultiPolygon) is created as an MPolygon object.

Here, when it is confirmed that two or more polygons share one polyline, the two or more polygons are regarded as forming a multi-polygon, and are managed as one MPolygon object.

On the other hand, if the polylines are not closed or crossing each other, the confirmation and analysis module 22 ignores them because the polylines cannot form polygons, and if there are independent polylines inside the polylines, it is determined as the corresponding HOLE. do.

For reference, multiple polygons consist of a plurality of polygons as one object.

In other words, if the number of polygons in the MPolygon object is 1, it becomes a Polygon object, and if it is more than 1, it becomes a MultiPolygon object.

As a result, the MPolygon object is a single polygon or multiple polygons treated as one object, and more efficient management of the polygon is possible.

The generation module unit 20 according to the present invention will be described in more detail.

The object selection module 21 of the generation module unit 20 checks the polyline shown in the numerical map, and the confirmation analysis module 22 checks whether the corresponding polyline is closed, or two or more polygons share one polygon, 4, the block diagram showing the configuration of the property information module unit according to the present invention, and FIG. 5 (in the present invention) The control module part scans the digital map, and the property information setting module part sets the property information, and the property module with the property information link creates the MPolygon object shown in the figure). , It is stored in the database module unit 70 as object data of an MPolygon object.

The scan module 31 of the attribute information setting module unit 30 scans the digital map recognized by the generation module unit 20, and the polygon location confirmation module 32 embodies the MPolygon objects 101, 102, and 103 , 104, 105).

In addition, the attribute information setting module 33 of the attribute information setting module unit 30 configures an attribute information table including MID, PID, and HOLE to set attribute information linked to each polyline.

Here, MID represents a eigenvalue for distinguishing an MPolygon from a digital map, PID represents a serial number of polygons belonging to the multipolygon, and HOLE is a hole for individual polylines belonging to the polygon. As a value indicating whether or not, if the value of the hole is 1, it means that it is a Hole object, and if the value is 0, it means that it is a Boundary object.

If the process of automatically setting the attribute information on the digital map by the attribute information setting module unit 30 according to the present invention is described in more detail, the scan module 31 of the attribute information setting module unit 30 is displayed on the digital map. One or more of the longitudinal scanning 111 and the transverse scanning 112 is performed.

In the embodiment according to the present invention, automatic setting of attribute information by the longitudinal scanning 111 will be described as an example.

As shown in FIG. 4, the scan module 31 of the attribute information setting module unit 30 longitudinally scans the numeric map output to the display module unit 70 to 111 to detect the polyline preferentially detected. Check in order.

Subsequently, the polygon positioning module 32 firstly checks the position of the detected polyline's MPolygon object and the construction polygon, and the attribute information setting module 33 determines the polygon's location based on the identified location information. Set attribute information in order.

In more detail, the scan module 31 of the attribute information setting module unit 30 sequentially detects the polyline while performing the longitudinal scanning 111, and the polygon positioning module 32 detects the poly The object polygon to which the line belongs is identified and recognized from the object data, and the attribute information setting module 33 sets the MID of the object to which the polyline belongs to the MPolygon object to '1'.

Subsequently, since the polyline was first detected in the MPolygon object, the target polygon identification code of the polyline is set to '1', and it is determined whether the polygon is a hole and HOLE if it is a hole.' Set to 1', and set to '0' if it is not HOLE.

Consequently, the attribute information setting module 33 automatically sets the attribute information of the polygon to (1,1,0).

Subsequently, the polyline positioning module 32 considers the next newly detected polyline as the next polygon, and the attribute information setting module 33 receives the polygon attribute information according to the above-described procedure. It is automatically set to (1,2,0), and the next polygon is automatically set to (1,3,0).

Through this process, the attribute information is continuously set automatically until all polylines are detected, and the first empolygon object 101 detects six polylines and automatically sets the attribute information in the polygon.

Next, when all the property information for each polygon of the first MPolygon object 101 is set, the second MPolygon object 102 is checked and the MID is set to '2'.

For reference, since the second MPolygon object 102 is composed of one polygon, the property information of the second MPolygon object 102 is automatically set to (2, 1, 0).

Next, the third (103), fourth (104), and fifth (Folygon) objects 105 are located on a similar height line.

However, even when a plurality of MPolygon objects 103, 104, and 105 are superimposed on a similar height line, the attribute information setting module unit 30 regards the polylines connected to each other as one MPolygon object First, it detects, belongs to the same MID, and also sets the PID by considering the polygon formed by the connected polylines as a single MPolygon object.

Accordingly, even if the polylines configured in the fourth MPolygon object 104 are first detected in the longitudinal scanning 111 process, rather than the polylines configured in the third MPolygon object 103, the third line is connected to each other. The compositional polylines of the MPolygon object 103 are combined into one MPolygon object to set property information, and the fourth polygonal object (104) constructional polyline parallel to this Independently set new attribute information.

Eventually, the property information of the third Empolygon object 103 is automatically set to (3,n,n) regardless of the position of the fourth Empolygon object 104, and the fourth Empolygon ( MPolygon) object 104 automatically sets attribute information to (4,n,n).

On the other hand, the fourth Empolygon (MPolygon) object 104 has a hole-type polygon, and thus the automatically set attribute information is (4,1,0) and (4,1,1).

Of course, the fifth Empolygon (MPolygon) object 105 is between the polygons having (4,1,0) and (4,1,1) as property information in the fourth Empolygon object (104). One location, but as described above, the attribute information is automatically set to (5,1,0) regardless of the fourth MPoligon object 104.

As described above, the attribute information setting module unit 30 scans the digital map to check the location order of the MPolygon objects, and the identified location order and the MPolygon confirmed by the generation module unit 20. ) After combining object information, property information for each polygon is automatically set and stored in the database module unit 70.

Meanwhile, as in the above-described embodiment, when two or more MPolygon objects on the same position line in the longitudinal scanning 111 are detected, the MPolygon objects are transversely scanned (112). The attribute information is automatically set in the order of detection.

The attribute information attachment module unit 40 links the set attribute information to the polyline as shown in FIG. 2B. Specifically, the poly forming the respective polygons by configuring the attribute information (MID, PID, HOLE) described above Link attribute information to a line.

This, when the polyline selected by the user on the digital map forms a multi-polygon, constructs attribute information accordingly and links the attribute information to each polyline.

On the other hand, when the polyline selected by the user in the digital map forms a polygon, the property information (MID, PID, HOLE) is configured as described above to link the property information to each polyline. At this time, the polyline may include a hole.

In addition, the search extraction module unit 50 searches the polyline on the digital map, generates the multi-poly accordingly, extracts the polyline within the multi-polygon, and registers the processing object as a boundary object when HOLE is 0. , When the HOLE is 1, the processing object is registered as a HOLE object, thereby storing and managing the property information of the MPolygon object.

Here, the MPolygon object stored in the database module unit 70 may be edited or modified and stored in another format for management.

The change module unit 60 converts the polygon into a closed polyline by adding, removing, or removing all property information of the mpoligon.

Specifically, the change module unit 60 considers and sets the geometrical relationship using the verification analysis module 22 together with the polylines belonging to the pre-registered MPolygon and the polylines selected by the user. As shown in FIG. 2C by reconfiguring the attribute information by the module unit 30 and attaching it to the polyline, a partial addition module 51 for adding polygons to the MPolygon and as shown in FIG. 2D Partial removal module 52 for partially deleting the polygon selected by the operator from the pre-registered MPolygon, and attribute information attached to all polylines belonging to the pre-registered MPolygon as shown in FIG. 2E. It includes a release module 53 for removing.

At this time, it is preferable that the release module 53 removes the pre-registered MPolygon object from the database module unit 70.

The object comparison module unit 100 compares the ground image of the object type, such as the MPolygon object, the polygon object, and the polyline object, completed according to the above-described process, and the terrain image that is the object of the polygon object. do.

To this end, the object comparison module unit 100 searches the database module unit 70 for the target terrain image of the digital map completed by polygon technology, and displays the terrain image and the ground image of the digital map based on the numerical coordinates. As shown in (the image showing the object comparison module according to the present invention comparing the ground image and the ground image of an object type such as an MPolygon object, a polygon object, and a polyline object), they are compared with each other.

As a result of comparison, it is confirmed that the position of the second ground image is out of position based on the second topography image.

The object correction module unit 110 confirms this, and FIGS. 7 (image showing the object modification module unit according to the present invention preparing to modify the position of the ground water image based on the terrain image) and FIG. 8 (object according to the present invention) As shown in the image of the correction module unit correcting the ground water image to match the terrain image), the target object is moved by moving the second ground image in line with the second terrain image, and the target object is a polygon object, a polygon object, and a polygon object. , Update the ground image of the object type such as a polyline object.

Eventually, after the operator completes the draft of the digital map of the object type, the image combination of the object comparison module unit 100 and the modification of the object modification module unit 110 can be corrected without having to check whether the position of the ground image is correct. Through the automatic processing, there is an effect that enables efficient and accurate error checking and processing.

Control module unit 90, as shown in Figure 2f, data input module unit 10, generation module unit 20, attribute information setting module unit 30, attribute information attachment module unit 40, search extraction By controlling the module unit 50, the change module unit 60, the database module unit 70, the display module unit 80, the object comparison module unit 100, and the object modification module unit 110, It performs the function of creating multiple polygons using attribute information.

Hereinafter, a method of generating attribute information of a digital map object through a system configured as described above will be described with reference to FIGS. 3A and 3B.

First, as shown in FIG. 3A, the control module unit 90 receives a digital map produced in a different file format (SHP, NGI, etc.) from an operator (S2). Although set, the present invention is not limited to this, and the operation is possible even in a state where only the execution screen (DWG surface) is executed.

Next, the control module unit 90 gives attribute information to the polyline (S4). That is, referring to FIG. 3B, the step S4 of assigning attribute information to the polyline, the control module unit 90 generates a new unique id value (S4a). Here, it can be understood that id represents a unique value for identifying a polygon or a multi-polygon.

Next, the control module unit 90 initializes to'count= 0'of PID to process the polygon object or the multi-polygon object constituting the digital map (S4b). Here, count can be understood as indicating the number of polygonal objects or multi-polygonal objects constituting a numerical map.

First, the control module unit 90 links the attribute information to the boundary polyline in the MPolygon object (S4c). Specifically, the control module unit 90 displays the polygon in the MPolygon object on the numerical map. After searching (S4c1), attribute information (MID, PID, HOLE) according to the polygon is generated (S4c2). At this time, it is preferable that the count is automatically set to'count+1', and the counting order of polygons is sequentially set according to the scanning order of the attribute information setting module 30 as described above.

The control module unit 90 sets the property information value of the extracted polygon to'MID = id, PID = count, HOLE = 0'(S4c3), and then sets the set property information to a boundary poly in MPoligon. Link to the line.

The control module unit 90 searches the HOLE polyline in the MPolygon on the digital map (S4d1), and then generates attribute information (MID, PID, HOLE) according to the polyline (S4d2).

The control module unit 90 sets the attribute information value of the extracted hole polyline to'MID = id, PID = count, HOLE = 1'(S4d3), and then sets the set attribute information to the hole polyline in the polygon. Link.

Next, the control module unit 90 searches for an MPolygon object with attribute information linked to the numeric map, and then selects the processed object (S6). At this time, the control module unit 90 checks the attribute information (MID, PID, HOLE) linked to the processed object (S8).

The control module unit 90 determines whether an MPolygon is searched among objects stored in the database module unit 70 using'MID' among the attribute information (S10).

In step S10, when the MP polygon is searched, the control module unit 90 determines whether the polygon is searched in the MP polygon using'PID' (S12).

In step S12, when the polygon is searched, the control module unit 90 determines whether'HOLE=1' (S14). That is, when the determination result of the step S14 is'HOLE=1', the control module unit 90 registers the processing object as a hole object in the searched polygon (S16).

Next, the control module unit 90 registers the polygon in the MP polygon (S18). That is, in the case of a newly created new polygon, a polygon is registered in the MP polygon. At this time, the control module unit 90 sets the unique key of the MPolygon as'MID' (S20).

Next, the control module unit 90 registers the MP polygon in the database module unit 70 (S22). This is registered in the database module unit 70 in the case of a newly created MPolygon.

Finally, the control module unit 90 registers and manages a new polygon and a new polygon that includes the new polygon in the database module unit 70.

On the other hand, when the determination result of step S14 is'HOLE=0', the control module unit 90 registers the processing object as a boundary object in the searched polygon (S24). If, in step S12, the polygon is not searched, the control module unit 90 generates a new polygon (S26).

In addition, in the step S10, when the MP polygon is not searched, the control module unit 90 generates a new MP polygon (S28).

In addition, the data input module unit 10, generation module unit 20, attribute information setting module unit 30, attribute information attachment module unit 40, search extraction module unit 50 constituting the system according to the present invention ), the change module unit 60, the database module unit 70, the display module unit 80, the control module unit 90, the object comparison module unit 100 and the object modification module unit 110 are configured in a board form And, it is mounted in the form of a server rack inside the case 200 as illustrated in FIG. 9.

At this time, the case 200 is a housing having a size of a human key as installed in a data center or the like.

In addition, a door 210 through which an operator can enter and exit for maintenance is installed on the front surface of the case 200, and cooling units 300 are installed on both sides.

In addition, a temperature detection sensor 220 is installed on the inner ceiling of the case 200, and a controller 230 is installed on the front upper side of the case 200 to detect the temperature value of the temperature detection sensor 220. Accordingly, the controller 230 controls the driving of the cooling unit 300.

Here, the reason for the need for the cooling unit 300 is that a plurality of modules mounted inside the case 200 in the form of a server rack has a high-speed processing speed, so a lot of heat is generated, so it is easy to deteriorate when cooling is poor. Therefore, it must be sufficiently cooled to prevent deterioration, and the door 210 should not be opened except for the repair period, which causes static electricity due to dust and the like, which may lead to short circuit, which may cause a signal processing error or a driving stoppage. Because.

For this reason, the case 200 needs to be cooled by an indirect cooling method.

To implement this, the cooling unit 300 includes a plurality of air-cooled pipes 310 fixed through each side surface of the case 200, as illustrated in FIGS. 9 to 11.

At this time, one end of the air-cooled pipe 310 is stepped so that a smaller diameter fitting part 312 is further formed.

In addition, the other end of the air-cooled pipe 310 is formed as an open end with an empty hollow portion 314 inside and fixed through the side plate of the case 200 so that the open end is exposed inside the case 200 do.

Therefore, the heat inside the case 200 enters into the hollow portion 314 through the open end of the air-cooled pipe 310, and is indirectly cooled while repeating the process of returning after being exchanged therein.

In addition, a cooling cylinder 320 is fitted to the fitting fixing portion 312, and a rubber ring 316 is fitted to an end of the fitting fixing portion 312 penetrating the cooling cylinder 320, so that the cooling cylinder 320 is detached. It will not be fixed.

In this case, since the rubber ring 316 does not provide a solid fixing force, the cooling cylinder 320 is formed by being woven in a grid shape, so it is not easily removed even if it is just a locking function. do.

In addition, the cooling cylinder 320 is assembled to correspond to the number of the air-cooled pipe 310, is connected to each other in communication by the link tube 330, the interior is kept empty so that air can flow.

In addition, the cooling cylinder 320 is connected by a link tube 330 to have a substantially lattice shape, and among them, an inlet 322 is formed in the cooling cylinder 320 corresponding to one side of the corner, and diagonally therewith. An outlet 324 is formed in the cooling cylinder 320 located at, and an air pump 340 is connected to the inlet 322.

Therefore, since the air pumped by the air pump 340 is outdoor air and has a lower temperature than the air inside the case 200, the hollow portion of the air-cooled pipe 310 during the process of circulating this air and escaping to the outlet 324 Indirect heat exchange with the internal air located at (314) cools the internal air.

Therefore, the air-cooled pipe 310 and the cooling cylinder 320 are preferably made of a material having excellent thermal conductivity, preferably copper and aluminum.

In addition, since a part of the air cooling pipe 300 is exposed to the outside air, cooling is also performed by indirect heat exchange through this part.

That is, according to the present invention, a cooling action by double interference heat exchange occurs.

In order to further strengthen this, in the present invention, a crossflow fan 350 may be further installed on the upper side of the cooling unit 300 as illustrated in FIG. 9.

The cross-flow fan 350 is a cross-flow fan, and the cooling cylinder 320 constituting the cooling unit 300 is blown by blowing wind as if forming an air curtain toward the cooling unit 300 installed directly below. It is possible to further increase the cooling efficiency by air cooling by air from the outside.

In addition, as shown in FIGS. 11A and 11B, since the case 200 is not well-opened, communication between the outside air and the bet may be necessary, and thus a ventilation unit 400 may be further installed on the upper surface of the case 200.

The ventilation unit 400 is fixed to the upper surface of the case 200 and the ventilation box 410 with an open top, a bottom surface of the ventilation box 410 and the case 200 penetrating the case 200 ) At least two or more ventilation passages 420 formed to communicate with the inside, and at least two of the rising check valves 430a and the falling check valves 430b, which are installed in opposite directions to the ventilation passages 420, and The upper portion of the ventilation box 410 is sealed to make a space there, but it is formed longer than the ventilation box 410 and assembled on the roof 440 having an awning and through the air passing through the side surface of the ventilation box 410. It includes a filter 450.

Thus, when the temperature of the inside of the case 200 rises due to heat, an airflow rising by convection is generated, so that the rising check valve 430a is opened by the airflow to be ventilated into the ventilation box 410, and the ventilation box 410 ) Inside, the cold air filtered by the filter 450 is waiting, and when the bet rises, the inside of the case 200 is then subject to internal pressure fluctuations, resulting in suction pressure, which causes the lower check valve 430b to open and the ventilation box Fresh and cold air inside 410 is introduced into the case 200 to be ventilated.

At this time, the rising check valve 430a and the falling check valve 430b have the same structure. Therefore, the structural description will be described with one reference numeral.

That is, the rising check valve 430a and the falling check valve 430b include a fitting fastener 432 fixed to the ventilation channel 420, a flange 434 formed at one end of the fitting fastener 432, and the The center plate 438 provided at the inner center of the end face of the fitting fastener 432 on which the flange 434 is formed and fixed by a plurality of fixing pieces 436 protruding from the inner circumferential surface of the fitting fastener 432 and the flange ( 434) formed on the inner peripheral surface of the end portion of the fitting fastener 432, the inclined machining in (IN), the flange 434 is in close contact with the opening (H) shielding piece (TR), and the shielding piece (TR) ) And a fastener (R) that penetrates through the center of the center plate (438) and is screwed onto the center plate (438), a head piece (HD) integrally fixed to the end of the fastener (R), and the fastener (R) is fitted between the shield piece (TR) and the head piece (HD) and the elastic piece (TO) for elastically pressing the shield piece (TR), and fitted to the fixture (R) and the shield piece It includes a spring (SP) disposed between the (TR) and the head piece (HD).

At this time, the inclined portion IN allows the internal air to rise and escape smoothly.

In addition, since the shielding piece TR is elastically pressurized while one spring SP and also one elastic piece TO complement each other, even if it is used for a long time, it is possible to prevent a decrease in airtightness due to a decrease in the elastic force of the spring. have. That is, even if the function of the spring SP is slightly deteriorated, the backflow prevention function is always accurately maintained because the elastic piece TO reinforces instead.

Due to the check valve 430, it is possible to implement an automatic ventilation function.

However, the ventilation unit 400 performs a cooling function in addition to the ventilation function, but the cooling efficiency is poor, so the above-described cooling unit is necessary.

In addition, in the present invention, as shown in FIGS. 12 and 13, the cooling plate 500 is further included to enhance the cooling efficiency and the cooling stabilization inside the case 200.

The cooling plate 500 includes a cooling frame 510 in the form of a frame, a cooling channel 520 in which each pipe welded and fixed around the inside of the cooling frame 510 is formed in a square frame shape, and the cooling channel 520. It includes a cooling piece 530 is fixed around the inner surface of the plurality of holes 532 are perforated.

Thus, one side of the cooling piece 530 is fixed to the open end of the air-cooled pipe 310.

In this case, it is preferable that the openings of the air-cooled pipe 310 are fixed with the holes 532 coincidentally but not closed.

To this end, the hole 532 may be configured such that the opening and the opening of the air-cooled pipe 310 correspond to each other, or may be formed only in a number corresponding thereto.

Therefore, the case of FIG. 12 is an exemplary drawing and is not necessarily limited thereto.

In addition, the cooling piece 530 is made of metal or copper or aluminum with excellent thermal conductivity, and also performs a self-cooling function according to heat absorption during internal heating.

In particular, the cooling channel 520 is a kind of buffering chamber space, and is configured to increase a cooling function by being filled with a cooling material therein.

Such a cooling material may consist of 5% by weight of benzene, 15% by weight of gadolinium sulfate, 5% by weight of terbium sulfate, 40% by weight of glacial acetic acide, and the rest of liquid paraffin to increase cooling characteristics, and injection is illustrated. Although not, it is preferable to maintain the form of sealing with a stopper after injecting through the inlet.

At this time, benzene is 5.5°C at a certain point, contributing to increase the cooling function, and gadolinium sulfate is a sulfur oxide of gadolinium (Gd), which is a rare earth element, and has a self-cooling property, thereby enhancing the storage effect. In addition, terbium sulfate also contains a rare earth element and has a cooling effect according to the self-cooling characteristics.

In addition, glacial acetic acid (Glacial Acetic Acide) has a freezing point at room temperature of 14.5°C or higher, which enhances the storage capacity.

In addition, the liquid paraffin is a typical PCM (phase change material) to enhance the cooling.

In addition, in the present invention, as illustrated in FIG. 14, the noise unit 700 may be further provided inside the case 200.

The noise unit 700 is intended to block vibration and noise generated when the plurality of modular boards mounted inside the case 200 are operated.

The noise unit 700 has a form in which a pair of meshes 720 are attached to both sides of the sound insulation plate 710 in which a plurality of sound insulation holes 712 are formed.

At this time, each of the sound insulation holes 712 has a tapered shape gradually narrowing in a funnel shape toward the lower portion.

That is, the noise unit 700 is installed on the inner bottom surface of the case 200, so that the narrowest side of the sound insulation hole 712 faces the bottom surface, and the wide side is disposed upward.

The reason for doing this is to maximize the noise attenuation effect by allowing the generated noise to collide and form a vortex, and to be diffused instantaneously through a relatively small diameter.

In particular, since the mesh 720 is attached to both sides of the sound insulation hole 712 to make a little space, the sound insulation effect described above can be obtained.
