Description

`` APPARATUS FOR OPERATING MANAGEMENT SYSTEM OF MEASURING POSITION OF CONSTRUCTION IN WATER AND SEWAGE UNDERGROUND FACILITY USING GPS}

The present invention relates to the operating device of the underground sewer pipe observing system using GPS, more specifically, the coordinates of the survey point immediately using the GPS to check the coordinates of the point immediately and in parallel with the field survey the origin of the underground facilities for future monitoring The present invention relates to an operation device of underground sewer pipe observing system using the improved GPS to improve the position recognition accuracy.

Water and sewage lines, various communication lines, and various infrastructures (hereinafter referred to as 'underground facilities') for constructing urban areas are buried underground and stored and protected.

Therefore, since the underground facilities are not exposed to the outside after being buried, the location of the underground facilities buried and the type of the underground facilities cannot be known.

However, in order to repair and manage the underground facilities in case of emergency, the location of underground facilities should be accurately identified, and the identified locations should be recorded so that the management of the relevant underground facilities, which is the target of the search, can be effectively performed.

Conventionally, a large number of measurement workers have been required to identify and record the location of underground installations.

To explain this in more detail, conventionally, when underground facilities are buried, one of the measurement workers stands with the target supported, and the other measurement workers use public survey equipment such as a total station on the ground before refilling the soil. After confirming the location of the target, the location of the underground facility was measured and calculated.

At this time, the conventional target is a well-known and common tool having a concave hemispherical shape called a prism, and the self-measuring work supporting the target adjusts the concave portion of the target toward the surveying equipment so that the surveying equipment transmits light waves toward the target. And the target specularly reflects the light waves to the origin position, and the surveying equipment is configured to receive the light waves again. In other words, to measure and record the location of underground facilities, at least two self-measurement tasks, such as self-calibration work that adjusts the targets to the surveying equipment and self-measurement workmen who operate the surveying equipment, must be put on site.

However, as the unit cost for measuring the location of underground facilities was lowered and the labor cost increased, the evasion of the service request for measuring the location of underground facilities occurred. However, the location measurement results of underground facilities are used as data for smooth protection and management of underground facilities as well as important foundation data for civil engineering and construction construction of adjacent areas. It is an indispensable task in the process of collecting information.

In addition, since the location measurement results of underground facilities are utilized as important foundation data for civil engineering and construction construction of neighboring areas as well as the protection and management of the relevant underground facilities, the reliability and accuracy of the location measurement results are very high. It is important.

Therefore, a method of economically performing the location measurement of underground facilities and ensuring the accuracy and reliability of the measurement results was required.

As one of the related arts to improve this, Korean Patent Registration No. 10-0973591 (2010.07.27.) "One-person surveying target for real-time location measurement of underground facilities" has been disclosed.

However, although the registered patent disclosed in the prior art has improved economics and efficiency through realization of a target of 1 when surveying, structural improvements that can stably support surveying equipment without flow are required.

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

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

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

The present invention uses the previously registered Patent No. 0973591 described later as it is. Therefore, all of the features of the device configuration described below are those described in the registered Patent No. 0973591.

However, the present invention has a main feature that is configured to prevent the shaking while being able to stably support the tripod among the components disclosed in the Patent No. 0973591.

Therefore, the device configuration, features and operation relations described below will be referred to the contents of the Patent No. 0973591 as it is, and will be described in detail with respect to the configuration associated with the main features of the present invention at the rear end.

As shown in Figures 1 to 3, the measurement target (100a) according to the present invention as a tool to accurately measure the location and depth of the embedding of various underground facilities, such as buried underground in the field to leave it in the record Attached to the underground facility, and is subject to the survey of public, public survey equipment 200, such as a total station.

Surveying target 100a according to the present invention is configured to be adjustable in length so that it can be detected by the surveying equipment 200 located on the ground regardless of the depth of the underground installation. More specifically, as illustrated in FIGS. 1A and 1B, the measurement target 100a includes a stator 110 connected to an underground facility, and a hinge 120 fixed to the stator 110. ) And a rod 130 that is rotatably fixed to the hinge 120.

The rod 130 may be composed of a tubular matrix 131 having a lower end connected to the hinge 120, and itself 132 for adjusting the length of the rod 130 while being inserted in the longitudinal direction of the matrix 131. Can be. For reference, two or more itself 132 may be connected in a row with the parent 131 so that the longest length of the rod 130 may be several times the shortest length. That is, by applying a conventional rod antenna connection structure to the rod 130 according to the present invention, it is possible to adjust the length of the rod 130 in a way to pull out itself 132 from the parent 131.

A vertical weight 131a may protrude from the lower end of the mother body 131 rotatably connected to the hinge 120. The vertical weight 131a is a protrusion protruding downward in a horn shape as shown in the figure, and indicates where the lower end of the rod 130 faces in the process of rotating the rod 130 based on the hinge 120. Allow self-measurement to be visually assessed.

At this time, since the distance between the vertical weight (131a) and the ground (or one point of the underground facility) is not relatively far, the self-measurement operation can recognize the direction of the vertical weight (131a) relatively precisely, and through this measurement The location of the survey target 100a identified in the equipment 200 may be tracked to which point of the underground facility.

Subsequently, a scale (not shown) may be formed on the outer surface of the rod 130. The scale allows the self-measurement operation to determine where the aiming point of the surveying equipment 200 is. Based on this, it is possible to calculate where the location of the underground facility indicated by the survey target 100a is.

The stator 110 is fixed to one point of the underground facility and is preferably made of a magnetic material while having a certain self weight. In general, underground facilities are mainly made of metal, especially magnetizable steel. In consideration of the characteristics of the underground facilities, if the stator 110 is made of a magnetic material, the self-measurement work on the site is a survey target (100a) by the stator 110 only by adjoining the survey target (100a) to the steel underground facilities; The stable positioning can be realized, and the measurement target 100a attached to the underground facility can maintain the current position stably against various natural forces such as wind even if no other self-measurement work is held. Self-measurement operation to operate the exact positioning can be done by yourself. In addition, the stator 110 may be manufactured to have a predetermined weight or more, so that the weight of the stator 110 may perform an anchor function even in an underground facility of a non-conductor material.

The hinge 120 is a means for fastening the stator 110 and the rod 130 to be rotatable with each other. The hinge 120 is fixed to the stator 110 via the rotation shaft 122, and the rod 130 and the fixing means 121 are fixed to each other. Is fixed by mediation. The rotating shaft 122 is rotatably engaged with the stator 110, so that the hinge 120 can rotate in the stator 110 about the rotating shaft 122, and the fixing means 121 rotates with the stator 110. A bolt 121a rotatably penetrating the 'c'-shaped frame 123 and the rod 130, which is fixedly possible, and a nut pressurizing the frame 123 to wrap and tighten the rod 130 to maintain the current state. It consists of 121b.

Therefore, the self-measuring operation adjusts the position of the rod 130 according to the site situation, and then tightens or loosens the nut 121b to move the nut 121b along the bolt 121a, thereby adjusting the position of the rod 130. The current position of the can be maintained.

As described above, the hinge 120 allows the self-measuring operation to move the rod 130 relative to the stator 110 to align the rod 130 in the field, as well as the fitted rod 130. It includes a function of fixing so that the vertical state of the. That is, the self-measurement operation is to rotate the rod 130 in the state of releasing the tightening of the nut (121b) to adjust the vertical state and then tighten the nut (121b) so that the hinge 120 wraps around the rod (130). It can be. On the other hand, the vertical state check of the rod 130 can be achieved through a known, common bubble tube (not shown). For reference, the bubble tube is a mechanism that checks the movement of the bubble, so that the self-measurement operation can visually check the horizontal state of the object in which the bubble tube is installed, it can be detachably fixed to the top of the rod 130, The measurement operation can adjust the rod 130 to the vertical state by rotating the rod 130 while visually confirming the bubble position of the bubble tube disposed on the top of the rod 130 on the ground (see FIG. 4).

The total station is a well-known and common surveying equipment 200 that can measure angles and distances together. Electronic theodolite and electro-optical instruments (EDM) are integrated into a single instrument. It is an electronic ranging and measuring device that can process the measured data quickly and output the result. The main types include the conventional wave filter, which adds the angle measuring function to the conventional wave filter, the optical type of theodolite which attaches the wave filter to the optical theodolite, and the main type of electronic theodolite which has the wave measuring filter attached to the electronic theodolite. Etc.

The general structure of the total station is composed of a trivet 210 for stable support, and a main body 220 that is fixed to the trivet 210. On the other hand, the main body 220 is a horizontal angle measuring unit 221, a vertical angle detector (not drawn out) for measuring the vertical angle generated by the vertical movement of the conventional wave measuring unit 221, and the horizontal angle measuring the horizontal angle generated by the left and right rotation of the main body 220 Four detection structures (not drawn out) and tilting sensors (not drawn out) for measuring and correcting the horizontality of the main body 220 are provided. Initially, the horizontal distance and the height difference were calculated separately later, but due to the development of electronic technology, a calculation function is built in the optical wave measuring device 221, and the detection part for measuring the vertical and horizontal angles is gradually miniaturized and lightweight. Has become. The total station type includes a conventional wave main body type having a side angle function added to the conventional wave side filter 221, an optical theodolite main body type in which an optical wave side filter 221 is attached to an optical theodolite, and an electronic theodolite. Electronic theodolite main body type with a wave side filter.

Subsequently, on the surface of the survey target 100a according to the present invention, a retroreflective body 130a in the form of a film for retroreflective packaging is packaged. Retroreflective refers to a phenomenon in which light from a light source is reflected from the surface of an object and returned to the light source. The retroreflective body 130a reflects the light in the direction of the light source regardless of the angle of light emitted from the light source. Has the nature.

As is widely known, the retroreflective body 130a forms irregularities formed in a concave shape in the form of a curved surface or a triangular curved surface, and has a shape as shown in the circle of FIG. Have

4 is a view showing an embodiment of the first embodiment, which will be described with reference to the drawing.

After installing the underground facilities 10 to be buried in the incision 30 to bury the underground facilities 10, and before refilling the incision 30, the self-measurement operation checks the location of the underground facilities 10. For example, the surveying target 100a according to the present invention may be installed in the underground facility 10. At this time, when the underground facility 10 is a magnetizable metallic material, the stator 110 having the magnetism configured in the measurement target 100a connects and fixes the measurement target 100a and the underground facility 10 by magnetic force. The survey target 100a is stably placed in the underground facility 10 without falling down.

On the other hand, in addition to the underground facilities 10, other underground facilities 20 may be buried together in the cutout 30, and as the buried position of the other underground facilities 20 is shown, immediately above the corresponding underground facilities 10. It may also be a location covering.

Therefore, when the arrangement of the underground facilities 10 and 20 is as shown, it is difficult to measure the position of the underground facility 10 located at the bottom with a straight rod-shaped measurement target.

However, since the surveying target 100a according to the present invention forms a pivotable structure through the hinge 120, the rod 130 of the surveying target 100a is straightly avoided by avoiding the underground facility 20 located above. In the ground, the self-measurement operation detects the rod 130 of the surveying target 100a straight out of the incision 30 by using the surveying equipment 200, and the actual burial position of the corresponding underground facility 10 located below. Can be measured.

In addition, since the rod 130 is rotatable with the stator 110 via the hinge 120, the outer surface of the underground facility 10 on which the stator 110 of the survey target 100a is seated is not inclined or flat. Even if the curved surface, the rod 130, which is entered on the basis of the stator 110 may be positioned so that it is always straight. For reference, the underground facilities 10 and 20 of the downtown area are buried adjacent to each other as well as the water and sewage pipes, various communication lines and underground wire lines, so it is difficult to check the location of the underground facilities 10 and 20 adjacent to each other. Can be. However, since the survey target 100a according to the present invention can avoid the interference of neighboring other underground facilities 10 and 20 so as to accurately identify the corresponding underground facilities, the location information data for the underground facilities in the downtown area. There is an advantage that the construction work can be performed accurately and relatively easily.

5 is a view showing a second embodiment of a survey target according to the present invention, will be described with reference to this.

The survey target 100b according to the second embodiment of the present invention further includes a support means 140. As shown in Figure 5 (a), the support means 140 is a clip 141 having a shape corresponding to the appearance of the underground facility 10, and is installed at one point of the clip 141, the survey target 100b It consists of a linker 142 detachably connected to the stator 110 of the).

Clip 141 is made of a material having a certain elasticity, as shown in Figure 5 (b) may be fixed to the underground facilities 10 while forcibly wrapping the periphery of the underground facilities 10 by the elasticity. It is made of a flexible material such as a belt, and the end is provided with a binding means such as a public buckle (not shown) or a Velcro tape (not shown). It may be fixed detachably as if wrapped. For reference, when an embodiment in which both ends of the clip 141 are fixed to each other through the binding means is applied, the length of the clip 141 may be manufactured to a sufficient length to wrap the circumference of the underground facility 10, or a rubber band. Of course, it must be made of a flexible material such as.

The linker 142 is fixedly disposed at one point of the clip 141, and is attached to and detached from the stator 110 positioned at the lower end of the rod 130. Since the stator 110 exerts magnetic force, a linker ( 142 is made of a material that is attached in response to the magnetic force.

As a result, the self-measurement work is to first wrap the support means 140 separated from the rod 130 in the underground facility 10 and then fix it, and then attach the stator 110 to the linker 142 of the support means 140, thereby providing a rod ( 130 is entered based on the linker 142 and the stator 110.

6 is a view showing a third embodiment of a survey target according to the present invention.

Surveying target (100c) according to the present invention is a structure of the shape of a cube, the outer reflector is packaged on the outer surface as well as the aiming point 101 for the aiming of the surveying equipment 200 is displayed. On the other hand, as shown in Fig. 6 (b) which is a cross-sectional view taken along the line AA 'of Fig. 6 (a), a stator 110' having a magnetism is built in the measurement target 100c to mediate the stator 110 '. Furnace is fixed stably to the underground facility (10). That is, when the measurement target 100c according to the third embodiment of the present invention is placed on the corresponding location of the underground facility 10 for which the self-measurement work is to be surveyed, the stator 110 'built in the survey target 100c is It is attached to the underground facility 10 by magnetic force and is fixed. Of course, the self-measurement operation is to move to the ground to aim the light wave measuring instrument 221 of the surveying equipment 200 at the aiming point 101 of the survey target 100c and then to emit light waves, the light waves of the survey target 100c After hitting the aiming point 101 is reflected by the retroreflective body is received by the surveying equipment 200. For reference, the surveying equipment 200 collects and processes information on the transmission and reception of light waves, and confirms the location information of the corresponding underground facility 10.

If the survey target 100c according to the present invention is a surface that can be fixed and fixed on the underground facility 10, the shape will not be limited, preferably as shown in Figure 6 it is good to form a tetrahedral shape will be.

The tetrahedron is a triangular surface having a triangular side surface, and thus forms a horn shape, so that the surveying equipment 200 located relatively upward can effectively sense and aim the aiming point 101 indicated on the side from the top, and faces the same direction. Since the area of the side surface is the largest among the cube having the same volume, it is possible to increase the reliability of the survey results when surveying through the survey equipment 200.

7 is a view showing a fourth embodiment of a survey target according to the present invention.

The fourth embodiment of the survey target 100d according to the present invention is a three-dimensional object having a hemispherical shape, and the survey target shown in the third embodiment includes a stator 110 'for binding with the underground facility 10. Same as 100c).

Since the hemispherical shape measurement target 100d faces the front in any direction from above, the surveying equipment 200 can receive the light waves that are specularly reflected in various directions, through which the surveying equipment 200 surveys the target 100d. Accurately collect and record information about these locations.

On the basis of such a configuration, the present invention eliminates the distance measurement error during geodetic survey by further combining the duplication technology of the distance measurement function as shown in FIG. 8 and the GPS measurement technology, and immediately confirm and store the coordinates of the underground facilities from the GS. It is configured to increase the accuracy by maximizing the convenience and to maximize the convenience and accuracy of the checking operation in the future monitoring.

For example, as shown in FIG. 8, the present invention is further provided with a laser range finder 230 in addition to the conventional wave measuring device 221 provided in the main body 220.

The laser range finder 230 is a laser oscillator, which is known as a unit for measuring a distance through a time difference of the laser beam that is returned through the reflector 130b after irradiating the laser beam.

To this end, in the present invention, a reflector 130b is further provided as a means for reflecting the beam emitted from the laser range finder 230 and reflecting it. The reflector 130b is a kind of a mirror, and the rod 130 Installed at a specific point on

Therefore, in the present invention, the primary distance measurement value obtained through the combination of the light wave measurer 221 and the retroreflective body 130a and the secondary distance measurement value obtained through the combination of the laser rangefinder 230 and the reflector 130b are obtained together. After that, by checking the difference of these values to eliminate the distance error, the distance measurement is implemented to enable more accurate distance measurement through duplication of surveying technology.

The reason for the reduction of the distance error is that even a slight angle error in the survey generates a significant distance error in practice, and this is even more so when displayed on a map.

For the duplication of such a distance measuring technique, the surveying equipment control unit 240 configured in the main body 220 is further provided with a comparison operation unit 242 and a memory 244.

The comparison operation unit 243 compares and reads the distance value measured by the laser range finder 230 and the distance value measured by the conventional wave measuring device 221 to check whether there is an error and to determine whether the measured values match. do.

At this time, the error range of the measured value is preferably ± 1 / 10000mm.

In addition, the comparison operation unit 243 stores each measured value in the memory 244 and then utilizes it in the comparison operation when the comparison operation, the calculated value is stored in the memory 244 again, input, output It is output through the unit 250 is displayed on the display provided in the main body 220 of the measurement equipment 200.

To this end, the input and output unit 250 is further connected to the surveying equipment control unit 240, the input and output unit 250 when the input for setting, or when outputting measurement data, arithmetic operation value, etc. Used.

In addition, the surveying equipment control unit 240 has a survey check unit 260 for confirming the field survey is assigned separately from the input and output unit 250 in the form of a separate button, when the surveyed calculated values and position check When the surveyor inputs a completion signal through the survey check unit 260 after the completion, the survey equipment control unit 240 completes the measurement operation, and the final measurement value along with the coordinate values by the GPS to be described later wireless communication unit By transmitting to a remote server (not shown) through the (270) is configured to terminate the field survey confirmation.

In this case, the remote server is a main survey server, and may be a server established by a management company, a national agency, or a local government agency.

In addition, the wireless communication unit 270 is provided with an antenna for communication, and configured to wirelessly communicate with the remote server, and is connected and controlled to the surveying equipment control unit 240.

In addition, the survey equipment control unit 240 is further connected to the GPS receiver 246 and the coordinate calculation unit 248.

The GPS receiver 246 receives GPS information through a satellite, and the received information is surveying equipment 200 through a combination of the surveying equipment control unit 240, the coordinate calculation unit 248, and the memory 244. From the coordinates of the main body 220, the position where the target is installed, that is, the position of the underground facility is accurately calculated as the coordinate value.

At this time, the previously measured distance measurement value is utilized.

As such, the wireless communication-based underground facility survey and field survey system according to the present invention can accurately measure the location of the underground facility by eliminating the distance measurement error, and stored and managed in a remote server with the location directly confirmed at the site. As a result, it will be possible to have accuracy in future monitoring.

In addition, the present invention, while maintaining the above-described structure as shown in the additional embodiment of Figure 9, to further improve the lower support structure of the trivet 210 to expand the contact area with respect to the ground when the point support, preventing structure against flow By having a stable and accurate survey can be configured.

To this end, a further embodiment according to the present invention further includes a support plate 300 rotatably configured on the side of the trivet 210.

The support plate 300 is configured so that the trivet 210 is attached to and fixed in a fixed state, and can be used to expand when necessary.

In particular, since the support plate 300 is composed of a wide plate shape when compared to the bed provided at the lower end of the trivet 210, the contact area with the ground is wider to provide a stable support force, not easily slipped the measuring point The effect of suppressing the defect can be obtained.

In addition, by providing a plurality of fine needles on the bottom surface of the support plate 300 can further increase the effect.

In addition, the support plate 300 is formed to be bent a part of the length in order to increase the operating efficiency, one end is rotatably fixed around the hinge axis 310 on one side of the trivet (210).

In this case, a lower torsion spring 320 is inserted into the hinge shaft 310, one end of the lower torsion spring 320 is fixed to the support plate 300, and the other end is fixed to the tricycle 210 to support the support plate. If the 300 is configured to have a property that is always to be rotated relative to the trivet 210 can make the operation easier and more convenient.

In addition, one end of the fixing guide 330 is hinged to one side of the length of the support plate 300.

When the fixing guide 330 is unfolded, the unfolding angle of the support plate 300 may be limited according to the inclination of the ground, in which case the support plate 300 may be folded without providing sufficient support force. Can be.

Therefore, the fixing guide 330 is provided in order to prevent this, the guide hole 340 is formed in a long rectangular shape in a part of the length of the fixing guide 330, the bolt groove 350 on the corresponding side of the trivet 210 ) Is formed, and the fixing bolt 360 is fastened to the bolt groove 350 by passing through the guide hole 340.

Then, when the bolt groove 350 and the guide hole 340 is fastened to the bolt groove 350 by the fixing bolt 360 at the point where the support plate 300 overlaps, the fixing guide 330 is fixed in position. Since the support plate 300 can also be fixed to a specific position.

On the other hand, the hook groove (370) is hinged to one side of the trivet 210 at intervals up and down the bolt groove 350.

The hook type fastener 370 is fixed to the front end of the support plate 300 by hook type, and the upper torsion spring 380 is provided on the axis that is the hinge point to enable the hook type fastener 370 to be elastically operated. By doing so, the support plate 300 is configured to be easily gripped.

At this time, the upper torsion spring 380 is fixed to the hook-type fastener 370 in one end in the state fitted on the shaft 390, the other end is fixed to the tricycle (210).

Accordingly, when the support plate 300 is normally rotated upward to be fixed by the hook-type fastener 370, storage and storage may be easily minimized while minimizing interference with surrounding objects.

Then, when it is necessary to use the hook-type fastener 370 slightly lifted the support plate 300 is unfolded while rotating automatically by the elastic force of the lower torsion spring 320 provided on the hinge shaft (310).

Thereafter, by stably supporting the interview on the ground by adjusting the spreading angle, the fixing guide 330 is fixed to the trivet 210 by fixing the bolts 360 to provide stable support.

On the other hand, in the case of unfolding and folding, it is possible to simply fold simply by performing in the opposite operation described above.

In addition, the lower end surface of the support plate 300 is further formed with a buffer operation groove 302, the fixing groove 304 is further formed at both ends of the buffer operation groove 302.

In addition, a plurality of coil springs CP are inserted into the buffer operation groove 302, and the coil springs CP are pressed by the buffer plate 306.

In addition, the buffer plate 306 has a fixed projection (FD) protruding at both ends, the fixed projection (FD) is inserted into the fixing groove (304).

In this case, the lower end of the buffer plate 306 is configured to protrude further downward than the support plate 300 in a state where the fixed protrusion (FD) is inserted into the fixing groove 304 is configured to perform a buffer function.

In addition, the fixing of the buffer plate 306 is made by the protrusion fixing piece 308, the protrusion fixing piece 308 is bolted to the bottom surface of the support plate 300 through the fixing piece bolt (FB) Is done.

In this case, the fixed groove 304 should be formed larger than the thickness of the fixed protrusion (FD) so that the fixed protrusion (FD) can flow in the interior even after the charge.

Therefore, when vibration occurs in the lower part, the vibration is first transmitted to the buffer plate 306, and the vibration is absorbed by the trituration 210 because the buffer plate 306 absorbs and absorbs through elastic absorption with the coil spring CP. It will not be delivered to the side, providing a more stable support.
