Description

Numerical map system that changes numerical map data for each reference point

The present invention relates to a numerical map system that changes numerical map data for each reference point in the field of numerical map technology. More specifically, a ground object image expressed as a polygon object type in a numerical map is precisely compared with an actual terrain image located at the corresponding point. Thus, it is possible to check the discrepancy point and adjust the numerical coordinates of the point or adjust the ground object image with the numerical coordinate position, while conveniently mounting the modules required for numerical map processing and preventing deterioration from heat to achieve longer lifespan And it relates to a numerical map system that changes numerical map data for each reference point improved to prevent processing errors in advance.

In general, in order to express the image of a ground object expressed on a numerical map as a geometric element, point, line, and plane drawing elements are used.

Specifically, if we look at the case of expressing the surface in the numerical map, various topographic features such as road boundary surfaces, buildings, actual width rivers, and water-buoy terrain boundary surfaces are expressed in surface form and displayed in color and pattern.

That is, in most cases, one surface-shaped object is used to express one feature, but there are cases where two or more surface-shaped objects are formed to express one feature.

Currently, most of the systems that edit or manage the numerical map express the surface shape as a polygon object. If another surface type exists inside the surface shape, the inner surface type object is called a hole.

In addition, a plurality of polygons to form one object is called a multipolygon (MultiPolygon).

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

In the case of performing input and editing operations for producing a numerical map (DWG file) using the above-described method, polygons and multi-polygons can be expressed only as a closed polyline with both endpoints connected.

At this time, polygon objects and multi-polygon objects do not exist. For example, when expressing a polygon with one hole, another closed polyline is displayed in the area inside the closed polyline, and multipolygons with two faces can be expressed separately as closed polylines.

However, since a single feature can be expressed as multiple objects, it requires a lot of attention from the operator by considering other related objects when inputting and editing a numerical map or searching for a feature on a numerical map. and work efficiency decreases.

In addition, in the case of a hole polygon, when displaying a color, it should be expressed so that the hole is not displayed, rather than the entire area is filled.

However, in the conventional hole display method, two closed polylines, that is, an outer polyline and an inner polyline are overlapped to cover the inner polyline (hole), or two polylines are selected respectively, so that one hole with a hole is formed. It cannot be expressed as an object.

In addition, additional work is required to maintain the object type when importing or exporting data formats of other systems that support polygons or multi-polygons.

That is, there is a problem in that the information of the separated object must be managed separately when importing, and the separated object must be edited into one object again in the system of the saved file when exporting.

On the other hand, numerical maps can be checked using the AutoCAD system. If the higher version of the CAD system is used, polygon and multi-polygon objects exist. However, when using the AutoCAD system, the files created in the higher version are in the lower version. It cannot be verified, causing compatibility problems.

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

Accordingly, a patent technology for a multi-polygon generation system using attribute information of a numerical map object and a method therefor, in which unique attribute information such as numerical coordinates are input for each polygon and the identification of polygons can be made automatically based on this, is disclosed. there is.

However, in this technique, since the operator must directly input the corresponding attribute information for each polygon according to the set rule, there is trouble and difficulty in the operation.

To explain this in more detail, in the prior art, in a numerical map in which regions or objects are divided by polygon units, the operator divides a plurality of polygons into one object and multi-polygons in which a plurality of polygons constitute one object, and one polygon constitutes one object. It is to directly classify and input the numerical coordinates of the corresponding point as attribute information to each polygon divided in this way, or input its own unique code linked to the numerical coordinates as attribute information.

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

Moreover, this manual method causes a positional discrepancy between the actual topographic image (aerial photographed image) of the aerial photographed point and the corresponding ground object image in the numerical map, thereby making it difficult to produce a precise numerical map.

In addition, the prior art, which proceeds manually, has a problem in that the object structure of polygons is limitedly utilized in a simple numerical map.

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 numerical map produced by using the numerical map production software (A) from an operator. A receiving data input module unit 10, a creation module unit 20 for generating an MPolygon object by selecting a polygon object from a numerical map by an operator and analyzing the geometrical relationship of the polyline composed of the polygon; An attribute information setting module unit 30 for setting the value of attribute information linked to a polyline, an attribute information attaching module unit 40 for linking the set attribute information to a polyline, and an empolygon ( The search extraction module unit 50 for searching MPolygon), the change module unit 60 for removing or maintaining the link state of attribute information linked to the polyline in the numerical map, and the MPolygon object as a list The database module unit 70 that registers and manages, and the display module unit that displays the MPolygon extracted through the search extraction module unit 50 using a screen or a separately provided output device so that the operator can check it. (80) and the object comparison module unit 100 for comparing the target topographic image with the numerical map on which the numerical map production of object types such as MPolygon object, polygon object, and polyline object has been completed, and the position of the comparison result The object correction module unit 110 that corrects the object having a difference in the terrain image according to the topographic image, and the components 10, 20, 30 according to the procedure of the operation program so as to search, create, and edit polygons on the numerical map. , 40, 50, 60, 70, 80, 100, 110 is composed of a control module unit 90 for controlling.

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

That is, it is possible to check the numerical map stored as the DWG file by using AutoCAD as an input.

Here, although the numerical mapping software (A) was 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 and analysis module 22 determines whether polylines are closed, whether there is a shared polyline between polygons. , after analyzing the geometric relationship in consideration of whether polylines intersect or whether there is an independent polyline inside the polyline, as shown in Fig. 2a through the object creation module 23, one polygon or multiple polygons (MultiPolygon) is created as an MPolygon object.

Here, if it is confirmed that two or more polygons share one polyline, the two or more polygons are considered to form a multipolygon and managed as one MPolygon object.

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

For reference, a multi-polygon is a plurality of polygons forming one object.

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

After all, the MPolygon object is one polygon or multi-polygon processed as one object, and more efficient management of polygons 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 20 checks the polyline shown in the numerical map, and the confirmation and analysis module 22 determines whether the corresponding polyline is closed, two or more polygons share one polygon, and 4 (a block diagram showing the configuration of the attribute information module unit according to the present invention) and 5 (in the present invention) The control module unit scans the numerical map, the attribute information setting module unit sets the attribute information, and the attribute information attachment module unit creates the MPolygon object shown in the drawing) , and 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 numerical map recognized by the generation module unit 20, and the polygon positioning module 32 is an MPolygon object 101, 102, 103. , 104, 105) are checked.

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 unique value for distinguishing MPolygons in a numerical map, PID represents a serial number of polygons belonging to a multi-polygon, and HOLE represents a hole for each polyline belonging to a polygon. As a value indicating whether or not the hole value is 1, it means a Hole object, and when the value is 0, it means a Boundary (boundary line as a strict meaning specified on a map or drawing) object.

When the process of automatically setting attribute information in the numerical map by the attribute information setting module unit 30 according to the present invention will be described in more detail, the scan module 31 of the attribute information setting module unit 30 is At least one of longitudinal scanning 111 and 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 performs longitudinal scanning 111 of the numerical map output to the display module unit 70 to select a polyline that is preferentially detected. Check in order.

Subsequently, the polygon positioning module 32 first confirms the position of an MPolygon object and a constituent polygon of the detected polyline, and the attribute information setting module 33 determines the position of the polygon based on the identified position information. Set the attribute information in order.

To explain this in more detail, the scan module 31 of the attribute information setting module unit 30 sequentially detects polylines while performing the longitudinal scanning 111, and the polygon positioning module 32 detects the corresponding polyline. The MPolygon object 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 MPolygon object to which the polyline belongs to '1'.

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

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

Subsequently, the polygon positioning module 32 regards the polyline newly detected by the scan module 31 as the next polygon, and the attribute information setting module 33 sets the attribute information of the polygon 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, attribute information is continuously and automatically set until all polylines are detected, and six polylines are detected in the first MPolygon object 101 and attribute information is automatically set to the corresponding polygon.

Next, when all polygon-specific attribute information 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 attribute information of the second MPolygon object 102 is automatically set to (2,1,0).

Next, the third 103 , the fourth 104 , and the fifth MPolygon object 105 are located on similar height lines.

However, even when a plurality of MPolygon objects 103, 104, and 105 are overlapped on similar height lines, the attribute information setting module 30 regards the polylines connected to each other as one MPolygon object. After detection, it belongs to the same MID, and at the same time, a polygon formed by polylines connected to each other is regarded as an MPolygon object and PID is set.

Therefore, even if the polyline configured in the fourth MPolygon object 104 is detected first in the process of the longitudinal scanning 111 rather than the polyline configured in the third MPolygon object 103, the third connected Property information is set by combining the constituent polylines of the MPolygon object 103 into one MPolygon object, and the constituent polylines of the fourth MPolygon object 104 are set in parallel with this. Independently set new attribute information.

As a result, the attribute information of the third MPolygon object 103 is automatically set to (3, n, n) regardless of the location of the fourth MPolygon object 104, and the fourth MPolygon object 104 is automatically set to (3, n, n). In the MPolygon) object 104, attribute information is automatically set to (4, n, n).

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

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

As described above, the attribute information setting module unit 30 scans the numerical map to confirm the position order of the MPolygon objects, and the MPolygon object identified by the identified position order and the generation module unit 20 by the MPolygon unit 20 as described above. ) by combining object information to automatically set attribute information for each polygon, and then store it in the database module unit 70 .

On the other hand, when two or more MPolygon objects on the same position line are detected during the longitudinal scanning 111 as in the above-described embodiment, the MPolygon objects are horizontally scanned 112 to correspond Attribute information is automatically set in the detection order.

The attribution information attachment module unit 40 links the set attribution information to the polyline as shown in FIG. 2B. Specifically, the above-described attribution information (MID, PID, HOLE) constitutes the polyline constituting each polygon. Links attribute information to a line.

In this case, when the polyline selected by the user on the numerical map forms a multipolygon, the attribute information is configured accordingly and the attribute information is linked to each polyline.

On the other hand, when the polyline selected by the user in the numerical map forms a polygon, the attribute information (MID, PID, HOLE) is configured as described above and the attribute information is linked to each polyline. In this case, the polyline may include a hole.

In addition, the search extraction module unit 50 searches for a polyline on the numerical map, generates a multi-polygon according to it, extracts a polyline within the multi-polygon, and registers the processing object as a Boundary object when the HOLE is 0. , by registering the processing object as a HOLE object when HOLE is 1, it stores and manages the attribute information of the MPolygon object.

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

The change module unit 60 converts the polyline to a closed polyline by adding or removing polygons to the MPolygon, or removing all attribute information of the MPolygon.

Specifically, the change module unit 60 considers and sets the geometric relationship using the analysis module 22 to check the polylines belonging to the pre-registered MPolygon and the polylines selected by the user to add them together. As shown in FIG. 2c by reconstructing attribute information by the module unit 30 and attaching it to a polyline, a partial addition module 51 for adding a polygon to an MPolygon, as shown in FIG. 2D A partial removal module 52 for partially deleting polygons 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 Includes a release module 53 for removing the.

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 surface image of an object type such as an MPolygon object, a polygon object, and a polyline object completed according to the above-described process and a terrain image that is a target of the polygon object with each other. do.

To this end, the object comparison module unit 100 searches the database module unit 70 for the target terrain image of the numerical map completed by polygon technology, and compares the terrain image and the ground object image of the numerical map based on the numerical coordinates in FIG. 6 As shown in (image showing how the object comparison module unit according to the present invention compares the ground image and the terrain image of object types such as MPolygon object, polygon object, and polyline object), they are compared with each other.

As a result of the comparison, it is confirmed that the position of the second ground object image is out of position with respect to the second terrain image.

The object correction module unit 110 confirms this, and FIG. 7 (an image showing the object correction module unit according to the present invention preparing to correct the position of the ground image based on the terrain image) and FIG. 8 (object according to the present invention) As shown in the image in which the correction module modifies the ground object image to match the terrain image), the second surface image is moved according to the second terrain image to become a target MPolygon object, a polygon object , update the ground object image of object type such as polyline object.

In the end, after the operator completes the draft of the numerical map of the object type, the image combination of the object comparison module unit 100 and the correction of the object correction module unit 110 are performed without the need to check whether the position of the ground image is correct. Since it is automatically processed through the system, there is an effect of enabling efficient and accurate error confirmation and processing.

As shown in FIG. 2F, the control module unit 90 includes a data input module unit 10, a generation module unit 20, an attribute information setting module unit 30, an attribute information attachment module unit 40, and a search and extraction unit. 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 correction module unit 110, It performs the function of creating multi-polygon using attribute information.

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

First, the control module unit 90 receives, from the operator, a numerical map produced in another file format (SHP, NGI, etc.) as shown in FIG. 3A (S2) In this embodiment, the resin map is received from the outside. However, the present invention is not limited thereto, and work is possible even in a state where only the execution screen (DWG side) is executed.

Next, the control module unit 90 gives attribute information to the polyline (S4). That is, referring to the step S4 of giving attribute information to the polyline with reference to FIG. 3B , the control module unit 90 newly generates a unique id value (S4a). Here, id can be understood as representing a unique value for identifying a polygon or multi-polygon.

Next, the control module unit 90 initializes the PID to 'count=0' in order to process the polygon object or the multi-polygon object constituting the numerical map (S4b). Here, count can be understood as indicating the number of polygon objects or multi-polygon objects constituting the 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 links the polygon within the MPolygon object on the numerical map. After searching (S4c1), attribute information (MID, PID, HOLE) according to the polygon is generated (S4c2). In this case, the count is preferably 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 attribute information value of the extracted polygon to 'MID = id, PID = count, HOLE = 0' (S4c3), and then converts the set attribute information to the Boundary poly in MPolygon. link to the line

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

After setting the attribute information value of the extracted Hole polyline to 'MID = id, PID = count, HOLE = 1' (S4d3), the control module unit 90 applies the set attribute information to the Hole polyline in the polygon. link

Next, the control module unit 90 searches for an MPolygon object to which attribute information is linked in the numerical 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 among the objects stored in the database module unit 70 is searched by using 'MID' among the attribute information (S10).

In the step S10, when an MPolygon is searched, the control module unit 90 determines whether a polygon is searched from the MPolygon by using the 'PID' (S12).

In the step S12, when a polygon is searched, the control module unit 90 determines whether 'HOLE=1' (S14). That is, when the determination result of 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 a polygon in MPolygon (S18). That is, in the case of a newly created polygon, the polygon is registered in MPolygon. At this time, the control module unit 90 sets the unique key of MPolygon to 'MID' (S20).

Next, the control module unit 90 registers MPolygon 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 MPolygon including the new polygon in the database module unit 70 .

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

Also, in the S10th step, if the MPolygon is not found, the control module 90 creates a new MPolygon (S28).

In addition, as illustrated in FIGS. 9 and 10 , the data input module unit 10 , the generation module unit 20 , the attribute information setting module unit 30 , and the attribute information attachment module unit constituting the system according to the present invention (40), search extraction module unit 50, change module unit 60, database module unit 70, display module unit 80, control module unit 90, object comparison module unit 100 and object modification A plurality of processing modules (MOD) including the module unit 110 are mounted on the block-type board 500, and a plurality of block-type boards 500 are installed inside the server room (ROM) at regular intervals.

At this time, the server room (ROM) performs data processing, storage, update, and redundant backup work for drawing within a space of a certain size like a kind of data center.

Here, the server room (ROM) always needs to be cooled with dry air because of the high heat generated in the data processing process, and dust or dust should not be generated. This is because, if a short circuit causes a power outage or power supply accident, not only the processing cannot be performed, but also the cost of data recovery is significantly high.

Therefore, a ventilation means capable of supplying dry air and exhausting the bet while excluding the cooling air containing moisture is required, and in the present invention, the ventilation unit 600 is connected to the front ceiling of the server room (ROM) by such ventilation means. They are installed symmetrically on the rear ceiling.

And, the block-type board 500 is mounted and detachably assembled on the base plate 400, which is the bottom surface of the server room (ROM), so that maintenance is easy. However, since it is sufficient to use any one of a plurality of known structures for such a mounting and detaching structure, there is no need to limit the present invention, so the illustrated description is omitted.

In addition, the block-type board 500 includes a plurality of slots 510 formed at regular intervals on one side thereof, and the processing modules (MODs) are mounted in the slots 510 .

In this case, the processing modules (MODs) are screwed and configured to maintain a stable connection relationship, and although not shown, the block-type board 500 is designed to receive commercial power supply, which is a general board mounting structure. You can think of it as an extension of the block form.

In addition, the ventilation unit 600 includes a unit housing 610, as illustrated in FIGS. 11 to 13 .

The unit housing 610 has a rectangular box shape, and a ventilation chamber 620 is formed in the center, with the ventilation chamber 620 interposed therebetween on both sides, respectively, an outdoor air inlet 630 and a bet outlet 642, a bet inlet (640) and the outside air supply outlet 632 are formed, the outside air intake 630 and the outside air outlet 642, respectively, and the inside suction port 640 and the outside air supply outlet 632, respectively, the first and second dividing walls (D1, D2) separated from each other.

In addition, the ventilation chamber 620 is provided with a hexagonal ventilation heat exchange tube 700, the upper and lower surfaces of the ventilation heat exchange tube 700 are partitioned to have a space divided to the left and right by the partition walls W1 and W2, respectively. .

In addition, first and second horizontal walls H1 and H2 are respectively fixed to the vertices of both sides of the ventilation heat exchange tube 700 in the longitudinal direction to partition the ventilation chamber 620 up and down to create an upper space and a lower space.

In this state, the first upper wall (R1) extending vertically from the first dividing wall (D1) to partition the upper space of the internal exhaust port 642, and the second dividing wall (D2) extending vertically from the outside air supply A second upper wall R2 that partitions the upper space of the outlet 632 is formed.

Due to this, the space between the outdoor air intake 630 and the ventilation chamber 620 becomes an external air intake room (S1), and the space between the bet suction port 640 and the ventilation chamber 620 is an internal air intake room (S2). The space between the bet discharge port 642 and the ventilation chamber 620 becomes the bet discharge room (S3), and the space between the outside air supply outlet 632 and the ventilation chamber 620 is the outside air supply discharge room (S4). ) becomes

Because of this, the outside air introduced into the outside air intake room (S1) can flow only to the upper side in communication with the ventilation chamber 620, so that it can be naturally sucked into the outside air intake part of the ventilation heat exchange cylinder 700. That is, as shown in the explanatory diagram of FIG. 12 , after being introduced into the second side of the ventilation heat exchange tube 700 and discharged through the fifth side, the outside air is introduced into the outside air supply outlet S4 and then the outside air supply outlet 632 through the server room (ROM).

On the other hand, the bet of the server room (ROM) is introduced into the bet suction port 640 and then flows into the sixth side of the ventilation heat exchange tube 700 through the inside introduction room S2, and after heat exchange with the outside air flowing from the inside After being discharged through three sides, it flows into the bet discharge room (S3) and then is discharged to the outside through the bet discharge port 642.

In addition, the exhaust ventilation fan (FN1) is installed in the bet discharge room (S3), the outside air sudden discharge (S4) is provided with a rapid blowing fan (FN2).

In addition, a replaceable outside air pre-filter (FT1) is built in the outside air intake room (S1), and the replaceable outside air pre-filter (FT2) is built in the inside air intake room (S2).

At this time, the outdoor air pre-filter (FT1) and the indoor pre-filter (FT2) are not shown, but when the cover (not shown) sealing the upper part of the unit housing 610 is removed, it is a sliding insertion type that can be easily lifted and replaced. It is assembled for easy replacement and use.

On the other hand, as shown in detail in FIG. 12 , the ventilation heat exchange tube 700 includes the first tube 710 constituting both ends of the ventilation heat exchange tube 700 and the first tube 710 to be in surface contact. The second cylinder 720, the third cylinder 730 arranged to be in surface contact with the second cylinder 720, and the second cylinder 720 and the third cylinder 730 are alternately a plurality of It includes a long bolt 740 that binds them in the arranged state.

In addition, the first cylinder 710 and the third cylinder 730 are first surface, second surface, third surface, and fourth surface in a counterclockwise direction based on the upper surface of the hexagonal ventilation heat exchange tube 700 , respectively. , the fifth surface, and the sixth surface, the first hole GO1 is formed on the second surface and the fifth surface, respectively.

In addition, the first cylinder 710 is molded in a closed state on one side, and has a cylindrical shape with the other side open.

In addition, the third cylinder 730 is molded in a state in which both sides are perforated.

In addition, the second tube 720 also has the same shape as the third tube 730 , except that the second hole GO2 is formed on the third surface and the sixth surface, respectively.

Furthermore, a long bolt hole 742 is perforated near the edge of the first, second, and third cylinders 710, 720, and 730, so that the long bolt 740 is easily inserted and fixed.

Therefore, there is an advantage that the capacity of the ventilation heat exchange tube 700 can be freely expanded or reduced.

In addition, the open surface of the first tube 710 and both sides of the second and third tubes 720 and 730 are each attached with Korean paper 750 .

The Korean paper 750 is not a simple Korean paper, but has durability while having humidity control properties so that when the outside air is indirectly heat exchanged with the outside air, moisture contained in the outside air is absorbed into the Korean paper 750 and dry air can be supplied, As the temperature-raised bet is discharged, the humidified Korean paper is dried to not completely block the bet and the outside air, but to also microscopically direct heat exchange through the Korean paper 750 to prevent dew condensation caused by the temperature difference. It also blocks mold growth, and only dry air can be supplied into the server room (ROM), increasing stability.

For this purpose, the base paper for making Korean paper is allophane powder 15.0% by weight, phosphorus pentoxide 5.0% by weight, abiestic acid 3.5% by weight, ethylene vinyl acetate 6.5% by weight, phosphite 5.5% by weight, petrolatum 4.0 and The remaining aluminum hydroxide-melamine mixture is immersed in an immersion solution for 1 hour and then dried before use.

At this time, the Allophane powder porous allophene clay mineral is pulverized to have a particle size of 0.01 mm or less and pulverized. Allophane is made of porous fine particles and has an excellent humidity control function.

As is known, it is reported to have 15 times the moisture absorption and moisture resistance of the moisture control wallpaper, so this characteristic is actively utilized in the present invention. Here, humidity control is a characteristic of being both dry and moist, and is representative of hanji. That is, when the humidity rises, it absorbs moisture to prevent dew condensation, and when the humidity goes down, it releases the retained moisture to control the humidity.

In addition, the phosphorus pentoxide is added to suppress hardening of paper to maintain flexibility and to prevent easy tearing.

In addition, the abiestic acid reacts with water to induce saponification of insoluble calcium, and through this, it strengthens water tightness by forming a strong oil film, but maintains micropores by the allopen powder, so it has antifouling properties without impairing the humidity control function. strengthen

In addition, the ethylene vinyl acetate is added to prevent scratching and tearing by enhancing the depositability of the liquid and strengthening the flexural modulus of the base paper.

In addition, the phosphites are added to suppress thermal deformation at high temperatures due to excellent chemical resistance and heat resistance.

In addition, Petrolatum is a petroleum product in the form of a gel mixed with soft and heavy oil, and it contributes to block thermal deformation by suppressing contraction and expansion according to temperature change.

In addition, the aluminum hydroxide-melamine mixed solution is to enhance heat resistance and flame retardancy, and a mixed solution obtained by mixing aluminum hydroxide and melamine in a volume ratio of 1:1 is used.

By configuring in this way, excellent ventilation is possible without a separate moisture removal and moisture removal facility, thereby effectively contributing to stabilization by dropping the temperature inside the server room (ROM).

In other words, in the case of supplying cold air using a cooler, a separate facility that can supply only dry air while removing moisture is required. Therefore, in addition to the cooler, the cost of installing moisture or moisture removal equipment and the space required to install them, etc. Considering that, the ventilation unit according to the present invention is very reasonable in terms of volume and space efficiency as well as cost.

In addition, in the present invention, as shown in the example of FIG. 14 , and an air flow path 570 is further formed inside the block-type board 500 , and the lower end of the air flow path 570 is the upper end of the fan box 520 . is disposed in communication with a slit-shaped air outlet 580 formed long in the longitudinal direction, a crossflow fan 592 is built in the fan box 520, and the crossflow fan 592 is a fan motor 590 It is configured to be rotationally driven by

In addition, a suction hole 522 is formed on one side of the fan box 520 , and a plurality of discharges communicating with the air flow path 570 is formed on a wall surface between the slots 510 of the block-type board 500 . A ball 524 is formed.

Therefore, when the cross-flow fan 592 is operated, dry indoor air is sucked into the suction hole 522 and then flows through the air outlet 580 through the air flow path 570 and the discharge hole 524 sequentially and is discharged into the slot ( The processing modules (MODs) mounted on the 510 are cooled.

In particular, since a temperature drop occurs when passing through a small hole with a strong pressure, the slightly cooled air may be discharged more effectively by increasing the pressure.
