It consists of a numerical synthesis module 170 for synthesizing the GPS coordinate information to the image to produce a digital map. Here, when the drawing module 120 completes the drawing of the ground structure (B) and the intersection (C) individually, sets the code so that the ground structure (B) and the intersection (C) can be individually identified, and the camera ( When the photographed image is generated by the 160, the photographed image is linked by the corresponding code, and the photographed image is shown in FIG. 9 (the figure showing the photographed image output on the numerical map produced by the survey data processing system according to the present invention). If one of the ground structure (B) or the intersection (C) is displayed on the digital map, the photographed image (I) linked to the ground structure (B) or intersection (C) is retrieved from the memory 150 To be printed. As a result, the numerical writing device 100 according to the present invention collects the horizontal position information and the altitude position information of the ground structure in real time and can perform the 3D geodetic survey on the terrain quickly and accurately, and the numerical synthesis module 170 ) Can use the collected information to complete more accurate digital map production.

On the other hand, the numerical value generating apparatus 100 is mounted on the collecting vehicle (V) for traveling on the road to receive the output signals transmitted from the transmitting node (200, 300), respectively, during driving, in particular a plurality of ground structures (B) All output signals transmitted by the ground structure transmitting node 200 should be received by the numerical writing device 100. However, the output signal of the ground structure transmitting node 200 has a limitation that the numerical writing apparatus 100 receives completely by the interference of the ground structure B, and through this, the numerical writing apparatus 100 receives the corresponding ground structure B. It is difficult to fully understand the shape of).

In order to solve this problem, in the editing system according to the present invention, any ground structure originating node 200 installed in the ground structure B may transmit all length information about the distance to the neighboring ground structure originating node at once. To help. As a result, when the numerical writing device 100 receives an output signal from any one of a plurality of ground structure originating nodes 200, 200 ', and 200 "(see FIG. 14) installed on the same ground structure B, the output signal is output. The length information, which is information on the distance between the plurality of ground structure originating nodes (200, 200 ', 200 ") includes all, the drawing module 120 of the numerical writing device 100 is the ground structure according to the length information We can draw (B) immediately and can complete.

A more detailed description thereof will be described in detail while explaining the configuration of the ground structure transmitting node 200.

Subsequently, by using the ground structure originating node 200 configured in the survey data processing system according to the present invention, the three-dimensional numerical coordinates can be accurately measured through GPS horizontal coordinates and level surveying of a specific ground structure. Since the structure can be used as a reference point, the user can visually recognize and utilize the reference point accurately.

The numerical synthesis module 170 has advertisement information layers 11 and 12 linked with the identification code of the ground structure B when the digital map is produced, as shown in FIG. 9, in the vicinity of the image of the ground structure B of the digital map. When the user utilizes the digital map, the corresponding advertisement information layers 11 and 12 are output to the ground structure image so as to be provided.

The advertisement information is continuously advertised until the digital map is updated, and if the digital map is planned to be updated, new advertisement information can be output from the updated digital map by updating the advertising information stored in the ground structure originating node 200. do.

The sending nodes 200 and 300 provide a communication module 210 that transmits its own identification code and a constant output signal in response to an operation signal of the calling module 130, and provides power for the operation of the communication module 210. It consists of a battery 220. On the other hand, the ground structure transmission node 200, in addition to the communication module 210 and the battery 220, the housing 230 (see Fig. 3) and the ground structure (B) mounted with the communication module 210 and the battery 220 The first and second cushions 240 and 240 'formed according to the outer wall shape while being closely attached to the outer wall of the) and the elastic frame frames 250 and 250' that support the folding housing 230. And first and second supports 260 disposed on both ends of the housing 230 and closely attached to the outer wall of the ground structure B to support the ground structure transmitting node 200 to be in close contact with the corner of the ground structure B. 260 ', the altimeter 280 for measuring the current altitude, the distance meter 280' for measuring the distance between the neighboring ground structure originating nodes 200, 200 ', and 200 "(see FIG. 14), and neighboring each other. All length information measured by the rangefinder 280 'of each ground structure originating node 200, 200', 200 "while communicating with the ground structure originating node 200, 200 ', 200" The storage module (M) and stores the received advertisement information by linking with the identification code of the ground structure source node (200, 200 ', 200 "), and the altimeter 280 to check the height spaced from the ground The altimeter 280 is configured with a correction meter 290 that corrects the altitude measured. The apparatus may further include an input module 210 ′ that receives the advertisement information and stores the advertisement information in the storage module M.

Numerical writing device 100 is installed in the movable collection vehicle (V) to receive and collect the corresponding identification code and output signal sent by the originating node (200, 300). GS 110 for this purpose confirms the absolute current position of the numerical writing device 100 while communicating with the satellite (A). The current position identification technology by the communication between the satellite (A) and the GPS 110 is a publicly known and public technology, and detailed descriptions of the apparatus, the application technology and the verification method necessary for the current position confirmation will be omitted.

The originating module 130 outputs a corresponding operation signal to transmit the identification code and the output signal by turning on the originating nodes 200 and 300 which are normally kept in an OFF state, and the communication of the originating nodes 200 and 300. RF signals of a frequency band that can be received and recognized by the modules 210 and 310 may be applied. The operation signal has a unique frequency band promised with the originating node (200, 300), the transmission may be made by the originating module 130 in a certain period. Since the operation signal should be effectively transmitted at a long distance with minimal interference in a complicated downtown area, the transmission frequency band should be low.

Receiving module 140 receives the identification code and the output signal transmitted from the sending node (200, 300) to check the identification code and the output signal, and transmits the identification code and the output signal to the drawing module 120 do. In more detail, the identification code and the output signal are identified by analyzing radio signals transmitted from the originating nodes 200 and 300, and in particular, the output signal detects the strength of the RSSI and the level information, respectively. Since the intensity of the first output signal originating from the originating node (200, 300) is constant, it is possible to calculate the distance between the originating node (200, 300) and the numerical writing device 100 by checking the RSSI of the received output signal. have. The distance calculation and the location check for this is performed by the drawing module 120, the description thereof will be described in detail while explaining the drawing module 120.

For reference, RSSI (Received Signal Strength Indication) refers to the average signal strength index at the receiver input generated by the measurement circuit of the receiver, and is typically used to check the distance between the receiver and the transmitter. .

On the other hand, the level information as described above includes information on the altitude of the point where the originating node (200, 300) is located, in the embodiment according to the present invention altimeter 280 installed in the ground structure originating node 200 And it is assumed that it is transmitted from the calibrator 290.

The drawing module 120 illustrates the surrounding terrain on which the collecting vehicle V is currently traveling according to the identification code and the output signal transmitted from the receiving module 140, and will be described with reference to the drawings.

3 is a view schematically illustrating a drawing module drawing a drawing image according to the present invention, which will be described with reference to the drawing module.

Collecting vehicle (V) according to the present invention moves along the road of downtown, the GPS 110 of the numerical writing device 100 confirms the current absolute position in real time while communicating with the satellite (A). On the other hand, the transmission module 130 transmits the operation signal at a predetermined cycle.

The communication module 210 of the calling node 200 or 300 adjacent to the collecting vehicle V receives the operation signal and transmits its own identification code and output signal in response thereto. In this case, as described above, the output signal has a predetermined intensity promised by all originating nodes 200 and 300.

On the other hand, the identification code has a unique code for each originating node (200, 300), in the case of a set of installed on the same ground structure (B) and the intersection (C) has a code structure to distinguish it.

In more detail, the identification code may have a format such as "B-012042-1" or "C-002457-3". Here, "B" or "C" is an identification number for identifying whether the identification code of the ground structure originating node 200, the intersection of the originating node 300, "012042" or "002457" is the ground. Designation number of the structure (B) or intersection (C), "1" or "3" is a division for distinguishing which number of outgoing nodes (200, 300) installed in the ground structure (B) or intersection (C) Number.

On the other hand, there are a plurality of outgoing nodes (200, 300) installed in the ground structure (B) or intersection (C), the outgoing nodes (200, 300) are to be arranged in a unified position according to the identification number. In other words, if the identification number is the same, all outgoing nodes 200 and 300 are arranged in the same position.

For example, the four ground structure sending nodes 200, 200a, 200b, 200c, and 200d, are arranged sequentially from left to right and top to bottom, and the ground structure sending node at this time. The identification number in the corresponding identification code that 200 has is '1', '2', '3', '4' in order of '200a', '200b', '200c', '200d'. Since this arrangement order of the ground structure originating node 200 is applied to the arrangement order of the other ground structure originating nodes, the drawing module 120 receiving the identification code is analyzed together with the RSSI signal of the corresponding output signal and all the grounds are analyzed. The location of the structure originating node 200 may be tracked. In more detail, since the division numbers are collectively applied to the ground structure originating node 200 at the same position, the first to fourth calling node 200a to received by the numerical writing device 100 of FIG. If the second outgoing node 200b and the fourth outgoing node 200d are larger than the first outgoing node 200a and the third outgoing node 200c, the ground structure ( It can be seen that B) is located on the left side with respect to the road, and through this, it is possible to estimate the appearance of the ground structure (B) by tracking all positions of the first to fourth calling nodes (200a to 200d).

In addition, in the survey data processing system according to the present invention, since the length information is transmitted between the neighboring ground structures first to fourth calling nodes 200a to 200d by linking the length code with the identification code, the ground structure system The position of the ground structure first to fourth originating nodes 200a to 200d can be traced and illustrated without receiving an output signal from all of the first to fourth originating nodes 200a to 200d. Of course, only the output signal and length information of only one of the plurality of ground structure transmitting nodes may limit the shape of the ground structure B, but some of the ground structure transmitting nodes may not receive the output signal. In this case, the shape of the ground structure B may be completely traced by supplementing the output signal of the ground structure originating node that has not been received through the length information.

On the other hand, it is possible to track the location of the intersection originating node 300 in the same manner, through which it can also determine the shape of the intersection.

For example, in the case of the first intersection, all the intersection identification codes and the intersection output signal of the first to fourth calling nodes 300a to 300d are received, and the first intersection is a cross-shaped intersection. However, in the case of the second intersection, only the intersection identification code and the intersection output signal of the second calling node 300b 'and the fourth calling node 300d' are received, confirming that the second intersection is a T-shaped intersection, In addition, it can be seen that the shape of the intersection is opened up and down and to the right.

According to the above description, the collecting vehicle V moves along the road, and the numerical generator 100 of the collecting vehicle V is a ground structure transmitting node 200b 'and 200c' installed in the second ground structure B '. 200d ') receives the ground structure identification code and the ground structure output signal.

Meanwhile, the drawing module 120 has not received the ground structure identification code and the ground structure output signal, but is confirmed by the ground structure identification code and the ground structure output signal of the other ground structure originating nodes 200b ', 200c', and 200d '. Based on the positions of the corresponding ground structure originating nodes 200b ', 200c', and 200d ', the position of the ground structure originating node 200a' that has not been received can be estimated. Can be. In addition, even if the collected vehicle V has not yet reached, the intersection identification code and the intersection output signal of the originating node of the next intersection have not been received, the estimated dotted line for the road can be shown. Of course, the lines temporarily shown as dotted lines may be shown as a solid line or modified in another direction when the intersection identification code and the intersection output signal of the corresponding non-received outgoing node are received and confirmed.

When the ground structure (B) and the intersection (C) are determined by receiving all the identification codes and the output signals of the calling node (200, 300), the code for identification of the corresponding ground structure (B) and the intersection (C) is set. You can specify this. As a result, the user can select a specific ground structure (B) or intersection (C) while viewing the numerical map as shown in FIG. Typically the selection can be made in a known, common touch screen method.

The drawing module 120 calculates the link quality indicator (LQI) through RSSI to compensate for the interference of the output signal by various obstacles in the downtown area, and through this, the accurate accuracy between the collecting vehicle (V) and the originating node (200, 300) is achieved. Track and verify distance.

The drawing module 120 combines the location information collected by the GPS 110 with the completed drawing image to complete the background of the numerical map. For reference, the reference point of the GPS location information as the intersection (C), when the collected vehicle (C) passes through the intersection (C) to check the corresponding location information through the GS 110, and the location information thus confirmed as a reference point To the drawing image. Typically, the location information is manufactured in a net shape around the reference point and then coupled to the drawing image. The combining process and the coupling device of the drawing image and the GPS position information are well-known and common techniques, and thus detailed descriptions thereof will be omitted.

The drawing module 120 may compare the drawing image, such as a digital map completed previously, with the currently confirmed information, and update and update the existing drawing image with the currently confirmed information. In addition, when the new drawing image is completed, the changed part may be partially post-modified compared with the existing drawing image.

The camera 160 directly photographs the ground structure B and / or the intersection C and links the photographed image I (see FIG. 9) to the corresponding code of the ground structure B and / or the intersection C. The memory 150 stores the same.

The memory 150 stores an existing drawing image, stores a new drawing image at the same time as the production, and stores a photographed image taken by the camera 160. The memory 150 is detachably attached to the numerical writing device 100 such as a USB memory. It would be desirable to apply.

The numerical synthesis module 170 completes the numerical map by synthesizing the GPS coordinate information to the drawing image completed by the drawing module 120. The GPS coordinates are synthesized based on a specific position in the drawing image. Proceed with information synthesis. The final technique for finalizing digital map by combining GPS coordinates with the background of the drawing image is a well-known and common technique in the field of digital map production. Therefore, here, the program source, technical principle, etc. applied to combine the drawing image and GPS coordinate with each other Detailed description will be omitted.

The originating nodes 200 and 300 may be divided into a ground structure originating node 200 and an intersection originating node 300. In the case of the intersection originating node 300, it will be sufficient if it is disposed at the corner of the intersection C, so that the communication module 310 and the battery 320 may be mounted in the enclosure for smooth communication with the numerical writing device 100.

The ground structure sending node 200 has a structure that can be fixed in close contact with the outer structure of the ground structure (B), since the ground structure sending node 200 has to transfer the external structure of the ground structure (B) to the numerical writing device (100). To this end, the following structure is formed, which will be described with reference to the drawings.

Figure 4 is an exploded perspective view showing the appearance of the outgoing node according to the present invention, Figure 5 is a plan view showing a state in which the bullet frame is installed in the outgoing node according to the present invention, will be described with reference to this.

Ground structure outgoing node 200 according to the present invention is a housing 230 for receiving and mounting the communication module 210 and the battery 220, and is in close contact with the outer wall of the ground structure (B) is fixed to the surface of the housing 230 The first and second cushions 240 and 240 ′, the ball frame frames 250 and 250 ′ supporting the folded housing 230 to be folded, and the housing 230 are disposed at both ends of the housing 230, respectively. ) Further includes a first and second supports 260 and 260 ′ that apply a physical force to support the ground structure B in a wrapped state. In addition, the ground structure originating node 200 according to the present invention communicates with the altimeter 280 installed at the bottom of the housing 230, and the ground structure originating nodes 200, 200 ', 200 "adjacent to each other Storage module for linking and storing all length information measured by the distance meter 280 'of the ground structure sending node 200, 200', 200 "with the identification code of the corresponding ground structure sending node 200, 200 ', 200". (M) and a calibrator 290 having a weight 293 arranged on the bottom of the altimeter 280 and fixed to fall toward the ground, The ground structure originating node 200 further includes information. It further includes an input module 210 'for receiving advertisement information from the input terminal 600 and storing it in the storage module (M).

The housing 230 is a pair of first and second panels 231 and 232 having a hollow plate shape for accommodating the communication module 210 and the battery 220, and the first and second panels 231 and 231. A hinge 233 for rotatably connecting the 232 and a pair of piezoelectric elements 234 and 234 ′ disposed on one surface of the hinge 233 in the first and second panels 231 and 232, respectively. Since the housing 230 forms a structure in which the first and second panels 231 and 232 are folded around the hinge 233, the left and right weights are preferably balanced. Therefore, it is preferable that the communication module 210 and the battery 220 are uniformly distributed in the hollows of the first and second panels 231 and 232, and it is advantageous to lower the center of gravity for stable coupling with the ground structure B. Therefore, the communication module 210 and the battery 220 are disposed to be positioned below the first and second panels 231 and 232. Meanwhile, magnetization bodies 231b and 232b are formed on the outer surfaces of the first and second panels 231 and 232. As the magnetizers 231b and 232b are attached to the laser 400 and the light receiver 500 by magnetic force, a plurality of ground structure transmitting nodes 200 and 200 'installed in the ground structure B are provided. Allow to be placed on the same height line. Description of this will be described below in detail with reference to FIG. 13. The magnetizers 231b and 232b may be any materials capable of reacting to the magnetic forces of the magnetic bodies 402 and 502 formed in the laser 400 and the light receiver 500, and a material such as iron may be generally applied. There will be. Of course, the permanent magnets may be applied to the magnetic bodies 402 and 502. The laser 400 and the light receiver 500 are configured with fixed panels 401 and 501 for mediating connection with the first and second panels 231 and 232, respectively. It is disposed on one surface of the fixed panel (401, 501) in contact with the two panels (231, 232).

Since the laser 400 or the light receiver 500 is temporarily required when the ground structure transmitting nodes 200 and 200 'are installed in the ground structure B, the laser 400 or the light receiver 500 is detachable from the first and second panels 231 and 232. It is desirable to achieve the structure possible. Therefore, the structure for allowing the laser 400 or the light receiver 500 to be detachable from the ground structure transmitting node 200 and 200 ′ without being limited to the presented embodiments is variously modified without departing from the scope of the following rights. Could be.

On the other hand, the hinge 233 is composed of a hinge axis 233a which is a central axis for rotation, the hinge axis 233a is a tubular shape having a hollow. This is to allow the antenna 211 for receiving and receiving the communication module 210 to be accommodated in the hinge shaft 233a. Subsequently, a rotary tube 233b is formed at the lower end of the hinge shaft 233. A line L is wound around the rotary tube 233b to be fixed, and the end of the line L is connected to a neighboring ground structure originating node 200, 200 ′, 200 ″ (see FIG. 14). When the end of (L) is released from the rotary tube 233b to be fixed to the neighboring ground structure transmission node 200, 200 ', 200 ", the rotary tube 233b starts to rotate and is connected to the rotary tube 233b. The rangefinder 280 'generates the length information by checking the rotation speed of the rotary tube 233b to measure the distance between neighboring ground structure transmitting nodes 200, 200', and 200 ".

The length information thus generated is stored in the storage module M (see FIG. 12).

On the other hand, the rotary tube 233b is wound in one direction by a spring spring so that the line L wound on the rotary tube 233b can connect neighboring ground structure transmission nodes 200, 200 ', and 200 "with sufficient tension. It would be desirable to be rotatably fixed.

For reference, the antenna 211 is a method in which a plurality of pipes are connected in a line to extend and contract, so that the ground structure transmitting node 200 is installed on the ground structure B, and then the antenna 211 is removed from the hinge 233. By making the withdrawal so that the sending module 130 and the receiving module 140 of the numerical writing device 100 can communicate smoothly.

Unexplained reference numerals “231a” and “232a” refer to “covers” for closing the opened hollows of the first and second panels 231 and 232, and refer to the first and second panels 231 and 232. The inserted communication module 210 and the battery 220 are prevented from being exposed to the outside.

The piezoelectric elements 234 and 234 ′ are disposed at positions where the first and second panels 231 and 232 are pressed against each other when the first and second panels 231 and 232 are folded to the maximum about the hinge 233, and thus, the first and second panels 231, The sensor 232 detects whether it is folded or unfolded.

The piezoelectric elements 234 and 234 'are electrically connected to the gas cylinders 271 of the impact protector 270, so that the opening / closing valve 271a of the gas cylinders 271 is opened in accordance with the electricity generation of the piezoelectric elements 234 and 234'. Gas will be released. Description of this will be described in more detail while describing the shock protector 270.

The first and second cushions 240 and 240 'are attached to one surface of the first and second panels 231 and 232 in contact with the ground structure B, so as to be closely fixed to the surface of the ground structure B. The surface is provided with a plurality of grooves 241, the surface is a smooth surface with excellent flatness, the material is a flexible material having elasticity. Therefore, when the first and second cushions 240 and 240 'are in close contact with the smooth surface of the ground structure B at a high pressure, the grooves 241 may be restored to a circular shape by elasticity after the air is discharged into the grooves 241. As air is not re-introduced, the air pressure in the groove 241 is lowered, and thus the first and second cushions 240 and 240 'are adsorbed onto the surface of the ground structure B.

Subsequently, as shown in Fig. 16 (a perspective view showing the appearance of the first and second cushions according to the present invention) and Fig. 17 (the front view schematically showing the operation of the first and second cushions), The first and second cushions 240 and 240 'are reinforced with an intake structure for the groove 241 so that the ground structure transmitting node 200 can be more firmly fixed to the ground structure B. Here, the intake structure means that the first and second cushions 240 and 240 ′ are in close contact with the wall surface of the ground structure B by forcibly lowering the air pressure in the groove 241. Installation grooves 240a are formed on the upper surfaces of the 240 and 240 ', and the cylinder 242 and the piston 243 are mounted to the installation grooves 240a, and the first and second cushions 240 and 240' The air passage 240b connected to the cylinder 242 while communicating with the grooves 241 is formed. Of course, an exhaust port 241a for opening the air passage 240b is formed in the groove 241 so that the air pressure of the groove 241 also changes according to the change in the air pressure in the cylinder 242.

As a result, the user pulls the piston 243 located on the upper surface of the first and second cushions 240 and 240 'from the cylinder 242 after closely contacting the ground structure transmitting node 200 to the ground structure B. 242 intakes air from the exhaust port 241a of the groove 241 while forcibly taking in the air in the air passage 240b. Therefore, as the air pressure in the groove 241 is finally lowered, the first and second cushions 240 and 240 'are closely adhered to the wall surface of the ground structure B.

Meanwhile, as shown in FIG. 17B, when the piston 243 is sufficiently pulled, the piston 243 should be held in place so that the air pressure in the groove 241 is kept constant. Thus, it further includes an anchor 244 to allow the piston 243 to hold in place.

In the embodiment according to the present invention, the anchor 244 is bolted, so that when the piston 243 is sufficiently pulled, the anchor 244 is tightened to fix the piston 243 at the corresponding position, through which the piston 243 is a cylinder. Return to 242 is prevented. The shape of the anchor 244 may be applied in various ways in addition to the bolt type.

The bullet frame 250, 250 'is to tighten the housing 230 so that the housing 230 covering the outer surface of the ground structure (B) exerts a grip on the ground structure (B), the ground structure outgoing node 200 is ground When installed in the structure (B), the first and second panels (231, 232) are forced to be in close contact with the outer surface of the ground structure (B) by the tightening force of the bullet frame (250, 250 ').

As shown in the figure, the bullet frames 250 and 250 'may be configured to enclose a plurality of housings 230 in a' U 'shape, and an installation position thereof may be formed on an inner surface or the inner surface that is in contact with the ground structure B. It may be one or more selected of opposing exterior surfaces. Since the bullet frame 250, 250 'should have elasticity, a metal material will be applied.

The first and second supports 260 and 260 'are rotatably fixed to the brackets 261 and 261' installed on the first and second panels 231 and 232, respectively, and to the brackets 261 and 261 '. The rollers 262 and 262 'and the springs 263 and 263' which rotate the rollers 262 and 262 'to one direction are comprised.

The brackets 261 and 261 'rotatably fix the upper and lower ends of the rollers 262 and 262', respectively, and are fixed to the first and second panels 231 and 232.

The rollers 262 and 262 'form a polygonal column shape and the circumferential surface is made of a highly viscous material to secure sufficient frictional force upon contact with the ground structure B. In general, a sticky resin may be applied to the surfaces of the rollers 262 and 262 ′ before the ground structure transmission node 200 is installed. As a result, when the rollers 262 and 262 'contact the outer surface of the ground structure B, the ground structure B and the rollers 262 and 262' are closely bonded to each other and fixed, and the first and second cushions 240 and 240 are fixed. ') Increases the contact force between the ground structure sending node 200 and the ground structure (B) while rotating in the direction to pull the ground structure sending node 200 toward the ground structure (B).

For reference, the springs 263 and 263 'are forced to rotate the rollers 262 and 262' by rotating the rollers 262 and 262 'before fixing the ground structure transmitting node 200 to the ground structure B. After preparing so that one side of the rollers (262, 262 ') is in close contact with the ground structure (B) as shown in Figure 6 (plan view showing the installation of the sending node according to the present invention) ground structure transmission The node 200 may be fixed to the edge of the ground structure (B).

To this end, the springs 263 and 263 'may form a coil connected to the rotation axes (not shown) of the rollers 262 and 262'.

The storage module M not only stores its length information generated by the distance meter 80 'but also stores length information of other ground structure originating nodes 200, 200', and 200 "installed in the same ground structure B. For this purpose, the ground structure sending nodes 200, 200 ', 200 "installed on the same ground structure B are connected to each other via a cable, and through this, the ground structure sending nodes 200, installed on the same ground structure B, The storage module M of 200 ', 200 "transmits all the information stored in the storage module M when the output signal is transmitted while sharing information with each other. For reference, the connection terminal C1 is configured at the end of the cable. In addition, the storage module M is configured with a socket S to which the connection terminal C1 is electrically detachably connected.

As a result, as shown in Figure 14, the ground structure outgoing nodes (200, 200 ', 200 ") installed in the same ground structure (B) share their length information while being connected to each other via a cable, and thus When transmitting the output signal, all of the length information of the neighboring ground structure transmission node (200, 200 ', 200 ") including its length information.

For reference, in order to clearly promise with the numerical apparatus 100 whether the length information of the ground structure originating nodes 200, 200 ', and 200 "is the distance from which ground structure originating nodes 200, 200', 200", The object of the ground structure originating nodes 200, 200 ', 200 "connecting the line L of the rotary tube 223b can be unified to the ground structure originating node located counterclockwise or clockwise. The length information linked to the ground structure originating nodes 200, 200 ′ and 200 ″ may be recognized by the numerical apparatus 100 in which direction the ground structure originating node is located.

10 is a perspective view showing the appearance of the altimeter and the correction system according to the present invention, Figure 11 is a calculation module schematically showing the impact of the first and second pressure sensors hitting the rotation axis of the correction system Figure 12 is a side cross-sectional view, Figure 12 is a block diagram showing the configuration of the altimeter and correction system configured in the ground structure transmitting node according to the present invention, will be described with reference to this.

The altimeter 280 is fixedly disposed at the lower end of the hinge 233, and a plurality of through holes 281 may be formed in the case so as to allow smooth aeration to measure air pressure and air density. On the other hand, a projection 282 for engaging the hinge 233 is formed on the upper surface of the altimeter 280, it may be to be firmly formed with the hinge 233. If the altimeter 280 is disposed at the bottom of the housing 230 closest to the ground, the fixing method and the fixing form may be applied in various ways, and may be variously modified without departing from the scope of the following rights.

The altimeter 280 can be divided into a barometric altimeter, which is measured by atmospheric pressure, and a radio altimeter, which is measured by the time taken for the pulse of radio waves emitted from an object in the air to reach the ground. The principle applies. For reference, the barometric altimeter applies the principle that the bellows made of thin metal material in a vacuum state expands and contracts according to the change in pressure, and the adjustment is necessary because a difference in the expansion and contraction ratio of the bellows occurs due to climate change. . The altimeter 280 using this principle is widely used as a portable electronic clock, and the structure thereof is also known and common technology, so a detailed description of the internal structure of the altimeter 280 is omitted here.

The calibrator 290 is disposed on the bottom of the altimeter 280 to calculate the ground altitude directly below the height of the altimeter 280 installed, and rotates on the altimeter 280 via the shaft 291a. Rotational wheel 291 which is fixedly possible, the string 292 wound by the rotational wheel 291, the weight 229 fixed to the end of the string 292 to generate a load, and the rotor 229 The first and second pressure sensors 294 and 295 for sensing the pressure by hitting the striking piece 291c protruding from the rotary shaft 291b of the rotating shaft 291b, and counting the number of times of pressure sensing of the first and second pressure sensors 294 and 295. And a calculation module 296 for checking the unwinding length of the string 292 and deducting the unwinding length from the altitude measured by the altimeter 280 to derive final level information. It may further include an output module 297 for displaying the number of revolutions and the rotation time of the rotary shaft 291b to adjust the drawing degree.

The rotary car 291 is rotatably fixed to the bottom of the altimeter 280 via the shaft 291a, and is wound in one direction by a spring spring so that the wound wire 292 is always wound up when the coil 292 loses tension. Make sure

The string 292 is wound around the rotor wheel 291 and fixed.

The weight 293 is fixed to the end of the string 292, so that the string 292 is tensioned so that the rotation difference 291 can rotate. Eventually, when the weight 293 free fall, the string 292 is subjected to tension, and the tension rotates the rotary wheel 291 while overcoming the elasticity of the spring spring supporting the rotary wheel 291. Therefore, it will be apparent that the weight of the weight 293 should exceed the elasticity of the spring.

The first pressure sensor 294 detects a strike of the striking piece 291c of the rotating wheel 291 that is rotated when the string 292 is unwound, and transmits a detection signal to the calculation module 296 every detection. do.

As shown in FIG. 10, the rotor wheel 291 is fixed to the bottom of the altimeter 280 by a pair of shafts 291a. At this time, the rotary car 291 is fixed to the shaft 291a around the rotating shaft 291b as shown in FIG. Accordingly, the rotation shaft 291b protrudes from the calculation module 296 which is disposed to face the rotation difference 291 around the shaft 291a, and the impact piece 291c protrudes from an end of the protruding rotation shaft 291b. . On the other hand, if the striking piece 291c rotates once along the rotation of the rotational shaft 291b, the first and second pressure sensors 294 and 295 may be hit, but the striking is performed via the presser 291d. Can be done. The presser 291d has a rod shape in which the center part is rotatably fixed. When one end is hit by the striking piece 291c, the other end hits the first and second pressure sensors 294 and 295 to pressurize it. However, unlike the present exemplary embodiment, the striking piece 291c may directly strike the first and second pressure sensors 294 and 295.

The second pressure sensor 295 detects a hit of the hit piece 291c of the rotating wheel 291 that rotates when the string 292 is wound, and transmits a detection signal to the calculation module 296 at each detection. do.

The output module 297 allows the user to check the number of strikes of the first and second pressure sensors 294 and 295 so that the unwinding degree of the string 292 can be adjusted to an initial position. Accordingly, the user may artificially adjust the unwinding degree of the row 292 and initialize the display state of the output module 297 to '0' so that the count starts from that time when the row 292 is unwinded. In more detail, the output module 297 may apply an output method such as seven segments, and may display '0' by pressing an initialization button. On the other hand, the output module 297 is set to add by '1' when receiving the detection signal of the first pressure sensor 294, and output by subtracting by '1' when receiving the detection signal of the second pressure sensor 295. Can be set to. As a result, the user may check the number of rotations of the rotation difference 291 through the number output from the output module 297, and may estimate the installation height of the ground structure transmission node 200 through this.

When the user installs the ground structure sending node 200 according to the present invention on the ground structure, the altimeter 280 installed on the ground structure sending node 200 may check the ground structure sending node 200 so that the current ground altitude can be accurately identified. Ideally, it would be ideal to install on the ground, but if the ground structure transmitting node 200 is located on the ground, the identification code and output signal transmitted from the communication module 210 may not be effectively transmitted to the numerical writing device 100.

Therefore, it is preferable that the ground structure transmitting node 200 is installed at a position as high as possible in the ground structure. In this case, since the ground altitude cannot be accurately measured, the calibrator 290 to correct the level information measured by the altimeter 280 is provided. Required.

Correction system 290 according to the present invention operates as follows.

First, the ground structure transmission node 200 is installed on the ground structure, and the wire 292 provided in the calibrator 290 is completely wound on the rotation wheel 291, and then the output module 297 is initialized.

When the output module 297 is initialized, the weight 293 of the compensator 290 is dropped freely, and the rotation speed of the rotation difference 291 counted by the output module 297 is checked.

The weight 293 may bounce by the repulsive force when it collides with the ground, and the inertia 291 may further rotate by the inertia. In this case, the striking piece 291c alternately strikes the first and second pressure sensors 294 and 295, and the first and second pressure sensors 294 and 295 detect or count the strike and count or decrease the number of times. The count is continued until the weight 293 is stably seated on the ground.

When the weight 293 is seated on the ground, the output module 297 finally outputs the count number, and the calculation module 296 calculates a height value having a length corresponding to the count number.

On the other hand, the altimeter 280 transmits the level information measuring the current altitude to the calculation module 296, the calculation module 296 calculates the corrected level information of the ground by subtracting the height value from the level information. . Of course, the corrected level information is transmitted to the communication module 210 and transmitted.

7 is a perspective view showing the appearance of the outgoing node according to the present invention, Figure 8 is a plan view showing the operation of the shock protector according to the present invention, will be described with reference to this.

The shock protector 270 is an electronic device such as the communication module 210 and the battery 220 from the impact due to the ground, when the ground structure transmitting node 200 is separated from the ground structure (B) for an unexpected reason. To communicate with the gas cylinder 271, the pipe 272 communicating with the gas cylinder 271, the shutoff valve 273 forcibly closing the pipe 272, and the end of the pipe 272. It is composed of a balloon 274 fixed to the arrangement.

The gas cylinder 271 is filled with a gas such as helium or carbon dioxide, which is a non-combustible gas, is compressed at a high pressure, and the discharge of the gas can be controlled by the opening / closing valve 271a. Here, the on-off valve 271a forms a conventional valve structure that is automatically opened and closed by an electric motor (not shown), and the operation of the electric motor is performed by the generated electricity of the piezoelectric elements 234 and 234 'under pressure. .

As a result, when the ground structure transmitting node 200 is separated from the ground structure B, the first and second panels 231 and 232 are folded around the hinge 233 by the shot frames 250 and 250 '. The piezoelectric elements 234 and 234 'generate electricity under pressure by folding the first and second panels 231 and 232, and the generated electricity is transferred to the on / off valve 271a so that the on / off valve 271a is Open the gas cylinder 271 to allow the gas to be discharged.

The pipe 272 is installed in the first and second panels 231 and 232 so as to communicate with the gas cylinder 271, and as shown, a plurality of ends are positioned at each corner of the first and second panels 231 and 232. do. Therefore, the gas discharged from the gas cylinder 271 moves along the pipe 272.

The shutoff valve 273 closes the pipe 272 so that the gas discharged from the gas cylinder 271 does not move through the pipe 272 even when the open / close valve 271a is opened, and the ground structure transmission node 200 is grounded. In the state in which it is not installed in the structure B, the gas discharged through the open / close valve 271a opens the pipe 272 even though electricity is generated instantaneously from the piezoelectric elements 234 and 234 'by closing the shutoff valve 273. Do not allow riding. On the other hand, when the ground structure outgoing node 200 is installed in the ground structure B, the shutoff valve 273 is opened so that the gas discharged from the gas cylinder 271 may move along the pipe 272 in case of emergency. Shut-off valve 273 for this purpose forms a conventional valve structure that can open and close the cross section of the pipe (272).

The balloon 274 is fixed to communicate with the end of the pipe 272, so that the balloon 274 can be expanded by the gas moved along the pipe 272. That is, when the ground structure originating node 200 is separated from the ground structure B, the balloon 274 swells rapidly while being inflated by gas, even if the balloon is inflated so that the ground structure originating node 200 collides with the ground. The shock is mitigated to minimize the damage caused by the shock.

Figure 13 is a plan view showing the installation of the ground structure outgoing node according to the present invention, will be described with reference to this.

Ground structure outgoing nodes (200, 200 ') according to the present invention is provided with a plurality of ground structure (B). At this time, since the output signal transmitted from the ground structure transmitting node (200, 200 ') includes the level information corresponding to the height value, in order to increase the reliability of the level information, the ground structure transmitting node (200) installed in the same ground structure (B) 200 ') would be preferably installed on the same height line as possible. To this end, the laser 400 is installed on the first and second panels 231 and 232 of the ground structure transmitting node 200, and the first and second panels 231 and 232 of the other ground structure transmitting node 200 'are adjacent to each other. ), A light receiver 500 is installed, so that the ground structure transmitting node 200 ′ can be disposed at a point where the light receiver 500 receives the laser light emitted from the laser 400.

In more detail, the laser 400 is fixed to the magnetization bodies 231b and 232b formed on the first and second panels 231 and 232 of the ground structure transmitting node 200 and the laser 400 is fixed from the corresponding laser 400. The irradiated laser light is irradiated horizontally. Here, a groove is formed at a point where the magnetizers 231b and 232b are disposed so that the position where the laser 400 contacts the first and second panels 231 and 232 is always constant.
