Spatial image drawing system that improves the precision of drawing

The present invention relates to a spatial image drawing system that improves the precision of drawing in the field of spatial image drawing technology. Reliable drawing image by quickly reflecting frequently changing topographical image images by using inexpensive and periodic drones instead of aerial photography using airplanes, which have a long and expensive aerial photography period and are expensive. In particular, it is a spatial image drawing system that improves the precision of drawing by preventing deterioration from heat while making it convenient to mount the modules constituting the management server, achieving longer lifespan and blocking processing errors in advance. it's about

In general, the drawing image used for making a numerical map is produced as a simple image as possible to help the understanding of the user using the map and to minimize the visual rejection.

In particular, in the case of devices, such as a navigation device, in which the user can quickly and easily check and understand the drawing image being output on the monitor, the background of the drawing image is clearly different from the actual appearance.

1 (a diagram schematically showing an illustrated image), (a) is a drawing image in which topographic information is simplified as much as possible, and (b) is a drawing image showing an actual topography.

As can be seen from FIG. 1 , in the case of (a), the road condition of the corresponding terrain and the arrangement of the feature image (B) can be easily and quickly understood by the user, but in the actual field, the corresponding drawing image and topography When comparing , users will feel confused about whether the actual site and the drawing image are identical due to the different features images (B, B') and the appearance between them.

In order to solve this problem, a system that can correct and update the drawing image has been developed.

This system checks the image of the feature by installing a position finder on the actual feature on the site, and collects the coordinate values and location information of the locator separately from the GPS, and the videographer measures separately from the image of the feature identified in this way. It is to update the existing drawing image stored in the numerical map DB by combining the coordinate values and location information.

However, since the position finder used in this system works in a state in which it is combined with GPS in the field, it was produced exclusively for the wilderness or relatively secluded outlying areas that are not obscured by various landforms.

Therefore, it is difficult to communicate with GPS satellites in the city center where high-rise buildings are concentrated, and it is impossible to accurately measure the location of the terrain in the city center where numerous jammers are flooded and malfunctions of various sensors are frequent.

In addition, there is a limit to installing a position measuring device in each building.

In addition, since aerial photography is expensive, it cannot be photographed periodically and repeatedly, so it is difficult to quickly reflect the shape characteristics of a feature that changes frequently.

In addition, in aerial photography, since the aircraft passes the filming point at high speed, it is impossible to stay in the filming area, so if necessary, the aircraft must be turned and re-photographed every time, resulting in a very large waste of time and money. Have.

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

As shown in Figure 2, the spatial imaging system according to the present invention is equipped with RF transmitters (R1, R2, R3) and GPS receivers (G1, G2, G3) to perform a coordinate reference point function. vehicles 100,102,104; Each RF transmitter (R1, R2, R3) is identified through the RF signal received from the RF transmitter (R1, R2, R3), and the coordinate information received from the GPS receiver (G1, G2, G3) is adjusted to the RF signal in accordance with the shooting zone. a drone 200 for generating coded photographed images for each transmitter (R1, R2, R3); and a management server 300 having a drawing module 330 for performing drawing by receiving the captured image generated by the drone 200 .

At this time, the vehicles 100 , 102 , and 104 include a vehicle controller 110 in which a memory is mounted as shown in the example of FIG. 3 , and RF transmitters R1 , R2 that transmit RF according to a control signal of the vehicle controller 110 , R2) is installed one for each vehicle.

In addition, each of the vehicles 100 , 102 , and 104 is provided with GPS receivers G1 , G2 , and G3 that communicate with a satellite under a control signal of the vehicle controller 110 to check location information, that is, coordinate information.

In addition, the vehicle stereo camera 120 is further installed on the roof of each of the vehicles 100, 102, and 104 to take a three-dimensional image image, which in the case of a tall building is taken by the drone 200 directly above it. Since the side image may not appear properly, the overall exterior image can be converted into a 3D stereoscopic image by acquiring the side image as a stereoscopic image and synthesizing it with a flat image.

In addition, the RF transmitters R1, R2, and R3 oscillate the RF so that the drone 200 can receive it, and the oscillated signal has a unique frequency band different for each RF transmitter R1, R2, and R3. Since one RF is included, the drone 200 can identify the RF transmitters R1, R2, and R3 that have oscillated the RF through the received RF.

In addition, the RF transmitters R1, R2, and R3 are controlled by the vehicle controller 110 installed in each vehicle 100, 102, 104 when the drone 200 enters the photographing target ground (ie, the photographing zone). It can be controlled to send continuously in bursts at intervals.

On the other hand, the drone 200 is equipped with a drone controller 210 for the control necessary to implement a function, including wireless communication with the management server 300 and the vehicle (100, 102, 104).

At this time, the drone controller 210 includes a camera 211 for photographing the shooting zone, an RF receiver 212 for receiving signals transmitted from the RF transmitters R1, R2, and R3, and the drone 200 is located The altimeter 213 for measuring the altitude, the coordinate system 214 for checking the GPS coordinates of the point where the drone 200 is currently located through communication with the satellite, and the position information and the coordinate system 214 received by the RF receiver 212 ) using the position information and the altitude information confirmed by the altimeter 213 to calculate the distance on the ground to each RF transmitter (R1, R2, R3), the calculator 215, and the calculator 215 The location information synthesizer 216 for synthesizing the location information on the photographed image of the shooting zone by checking the distance information and the location information received by the RF receiver 212, and the drone memory 217 for storing the synthesized video image. include

In this case, the camera 211 is a general camera for photographing the photographing zone, and an analog method or a digital method may be applied, but particularly preferably, a stereo camera for a drone is used to secure a stereoscopic image.

In addition, the RF receiver 212 identifies and distinguishes the RF included in the oscillation signal corresponding to the different frequency bands transmitted by the RF transmitters R1, R2, R3, and the distinction information is recognized by the drone controller 210 do.

In addition, the calculator 215 is, as in the example of FIG. 4, the RF transmitters (R1, R2, R3) and the GPS receivers (G1, G2, G3) disposed in at least three of the circumference of the shooting zone are mounted vehicles 100, 102, 104. ) and the information provided by the drone 200 hovering at a certain height above the shooting zone, that is, the image of the size of the unit space that the camera 211 mounted on the drone 200 can shoot at once. By inserting coordinate values, that is, location information into the image, the drawing module 330 calculates how far away from the drone 200 to accurately determine the location information of the vehicles 100, 102, and 104 so that accurate drawing is possible. it is to do

At this time, the position of the drone 200 is known through the coordinate system 214, and the ground point directly below the drone 200 in the shooting zone is known through the altimeter 213, and each RF transmitter (R1, R2, R3) Since the distance can be known through the speed of the RF and the time received by the RF receiver 212, the distance from the ground point directly below the drone 200 in the shooting zone to each RF transmitter (R1, R2, R3) is a right triangle. Therefore, it is calculated by the Pythagorean theorem.

In this way, based on the ground point directly below the drone 200 in the shooting zone, the coordinate values obtained by each GPS receiver (G1, G2, G3) and the distance information from the reference point to the RF transmitters (R1, R2, R3) are known. Therefore, it is possible to display the location information of the RF transmitters (R1, R2, R3) on the video image of the shooting zone that is eventually taken, and through this, when drawing the video image of the shooting zone based on each location information, accurate drawing becomes possible

Then, the drone memory 217 records the photographed image in which the location information is synthesized in the form of a storage, and then transmits it to the drawing module 330 according to the control signal of the drone controller 210 .

The drone memory 217 may be, for example, an external disk having a temporary storage function such as RAM (a recording medium detachable by USB method, or a recording medium in the form of an SD card), or a general disk, or a removable hard drive. It could be a drive.

Meanwhile, the management server 300 is installed in a remote server room (ROM, see FIG. 5), and includes a server controller 310 that is a main control unit, and the server controller 310 includes the drone 200 and wireless A server communication unit 320 for communicating and receiving a video image required for drawing, a drawing module 330 for drawing using the video image received through the server communication unit 320, and the server controller 310 are connected and A server memory 340 for storing transmitted and received information is mounted.

In addition, although not shown, the management server 300 has a plurality of processing modules (MOD, see FIG. 6 ) necessary for calculation and a database (Data Base) for storing information in addition to the drawing module 330. Therefore, a detailed description will be omitted.

At this time, as in the examples of FIGS. 5 and 6 , a plurality of processing modules (MOD) including the drawing module 330 are mounted on the block-type board 500, and a plurality of block-type boards 500 are spaced apart from each other. It is installed inside the server room (ROM).

That is, the server room (ROM) performs data processing, storage, update, and redundant backup operations for drawing in 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 management server 300 is mounted and detachably assembled on the base plate 400, which is the bottom surface, 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, and the slot 510 has a DB or drawing module 330 constituting the management server 300 described above. Modules including, that is, the processing module (MOD) is mounted.

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. 5 and 7 to 9 .

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 in the explanatory diagram of FIG. 8 , 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 ) is closed. 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. 8 , 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 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 in the example of FIG. 10 , step motors M1 and M2 are respectively installed on both longitudinal sides of the ventilation heat exchange tube 700 , and a dehumidification filter (RF) is installed on the rotation shaft of the step motors M1 and M2. ) to be fixed to one end of the inlet of the ventilation heat exchange tube 700 through which outside air is introduced according to the rotational direction of the step motors M1 and M2, that is, the first hole GO1 formed on the second and fifth surfaces, respectively. may be configured to selectively open and close.

For example, on rainy or high humidity days, the outside air introduced through the dehumidification filter (RF) is filtered once more to strengthen the dehumidification function based on the information detected by the humidity sensor, so that the moisture is transferred into the server room (ROM). It is more preferable to block the inflow.

At this time, the dehumidifying filter (RF) is filled with a plurality of silica gels 774 having a ball shape inside the filter housing 770 having a plurality of through holes 772, and the outside of the filter housing 770 is a nonwoven fabric 776. has a structure overlaid with

In addition, the dehumidifying filter RF is disassembled and screw-assembled on the fixed shaft 780 vertically fixed to the rotation shaft ROT.

Therefore, the dehumidifying filter (RF) is easy to replace and use, and it is also easy to replace the silica gel (774).

In addition to this, in the present invention, as shown in the example of FIG. 11 , and inside the block-type board 500 , an air flow path 570 is further formed, and the lower end of the air flow path 570 is the fan box 520 . The crossflow fan 592 is built in the fan box 520 and is disposed in communication with the slit-shaped air outlet 580 formed long in the longitudinal direction at the upper end, and the crossflow fan 592 is the fan motor 590 ) to be rotated 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.

In addition, in the present invention, as shown in FIG. 12 , the base plate 400 , which is the bottom surface on which the block-type board 500 constituting the management server 300 is installed, has a rectangular groove in the form of irregularities at regular intervals in the width direction. A 410 may be further formed, and the square groove 410 may have a structure in which the desiccant 420 is filled.

In this case, the desiccant 420 is in the form of a layer, a charcoal layer 422 laid on the bottom surface, an activated carbon layer 424 laid on the charcoal layer 422, and the activated carbon layer 424 spread on the It is composed of a silica gel layer 426 and a nonwoven fabric layer 428 covered on the silica gel layer 426 .

Here, the charcoal constituting the charcoal layer 422 performs dehumidification and moisture absorption functions and purifies the air, and the activated carbon constituting the activated carbon layer 424 performs odor and odor purification and moisture absorption functions, and the silica gel layer The silica gel constituting (426) is responsible for the main moisture absorption and moisture removal functions.

With this configuration, moisture is kept close to zero inside the server room (ROM), thereby stabilizing the internal environment.
