Description

A geodetic surveying system that can create maps of geographical features based on GNSS {GEODETIC SURVEY SYSTEM FOR CREATING MAP BASED ON GNSS}

The present invention relates to a geodetic surveying system, and more specifically, to a geodetic surveying system that can produce maps of geographical features based on GNSS.

In general, for public surveys and underground facility surveys ordered by public institutions such as the government, geodetic surveys must be conducted first. Geodetic surveying refers to various activities such as measuring horizontal distance, elevation difference and direction, determining the location of each measurement point, displaying this in drawings or figures, and staking out on site.

Among geodetic surveys, level surveying is a survey that determines the height difference between two points using measuring devices such as a marker, level, and total station. The accuracy is 5mm * S/2 for level 2 surveying (here, S is a one-way distance (unit is km), so detailed measurement is required.

To briefly explain this Total Station, the Electronic Theodolite and Electro-Optical Instruments are integrated into one device.

The structure of the TotalStation is largely divided into four parts: a vertical angle detector that measures the vertical angle created by the vertical movement of the telescope, a horizontal angle detector that measures the horizontal angle created by the left and right rotation of the main body, and a horizontal angle detector that measures the distance from the center of the main body to the prism. It is an electronic rangefinder and goniometer that consists of a distance measuring unit that measures the distance and a tilting sensor that measures and corrects the horizontality of the main body. It processes the measured data in a short period of time and outputs the results.

When conducting a geodetic survey through a total station, it is confirmed through standard surveying whether the coordinates of the reference point set through a certain standard are accurate, and the distance between terrains or the elevation of the ground surface is measured based on these reference points to confirm the exact coordinates.

However, the conventional geodetic survey method has the problem of significantly impairing the efficiency of geodetic survey work due to the inconvenience of having to repeatedly install and dismantle the total station and the time disadvantage due to the limitation of surveying the measurement target area one time.

In addition, in the conventional geodetic survey method, detailed elevation measurements using a total station are virtually impossible, so elevations are measured in units of certain areas, and there is a problem in that the reliability of the information obtained is low.

It is a diagram showing the curvature of the ground surface as a graph, and Figure 5 is an image showing the output of ground images collected by the geodetic surveying system according to an embodiment of the present invention.

The geodetic surveying system according to the present invention includes an information collector 100 that is installed on a vehicle (V) driving in the field and collects information for producing a map, and an information collector 100 that is installed on a ground surface with a slope of 0 degrees to determine the initial level of the slope detector 130. It includes a reference coordinate transmitter 30 that sets the location as a reference point while allowing confirmation of whether the location is accurately determined.

Here, the reference coordinate transmitter 30 records the GNSS (Global Navigation Satellite System) coordinates of the installation location to perform the function of the reference point, and the record is provided to the worker, so that the coordinates are used when collecting spatial information using the vehicle (V). In addition to confirmation, it is used as a standard for checking whether there is an error in the tilt detector 130.

The information collector 100 includes a GNSS receiver 110 to check the current location of the vehicle V while driving, a detachable fastening part 300 mounted on the upper surface of the vehicle V, and a detachable fastening part 300. A magnetic lift unit 400 installed at the top, a camera 120 that is coupled to the top of the magnetic lift unit 400 and collects real-time images by photographing the surroundings of the vehicle (V), and a bird installed on one side of the vehicle (V). An extermination unit 500, a slope sensor 130 that detects the curvature of the ground surface, a storage device 140 that links the actual image and a graph reflecting the curvature of the ground surface with GNSS coordinates and stores it, and a vehicle (V) An altimeter 160 that measures the current altitude of the vehicle, a mileage confirmation device 180 that checks the mileage of the vehicle V while linking with the mileage device 20 of the vehicle V, and a slope detector 130. The curvature state of the ground surface is calculated and processed through the curvature state (slope) of the ground surface detected by the altimeter 160, the altitude detected by the altimeter 160, and the driving distance of the vehicle (V) confirmed by the mileage confirmation device 180, and this is converted into two-dimensional terrain. A control device (170) that applies it to the image to complete it into a three-dimensional terrain image, while receiving a reference signal transmitted from the reference coordinate transmitter (30) and comparing it with the current detection signal transmitted by the slope detector (130) to determine whether there is an error; , the operator inputs a manipulation signal to operate the information collector 100, the input/output device 150 receives and outputs the output signal of the information collector 100, and the reference coordinate transmitter 30 is driven to transmit the reference signal. It includes a signal transmitter 190 that transmits a signal.

The GNSS receiver 110 is a known and shared device that communicates with one or more artificial satellites 10, etc., and displays the actual image, which is information collected by checking the current GNSS coordinates of the vehicle V, and a graph showing the curvature of the ground surface. Link this. Since the GNSS receiver 110 is a known and shared device that can track the GNSS coordinates where it is currently located, here, a method for communicating with the satellite 10, a method for tracking GNSS coordinates, and electrical, electronic and Detailed description of the mechanical configuration is omitted.

One or more cameras 120 are installed in the vehicle V to simultaneously photograph various directions on the ground while driving. Figure 5(a) is an image taken of the front right side of the vehicle, Figure 5(b) is an image taken of the rear right side of the vehicle, and Figure 5(c) is an image taken of the front front of the vehicle.

The real-life images captured in this way are composed of map information and can be used for various purposes.

For reference, since the GNSS coordinates received by the GNSS receiver 110 are recorded in the real-time image, it is linked and stored at the corresponding location on the map, and through this, the user selects the corresponding point on the map and simultaneously outputs the real-time image. You will be able to check it.

The tilt detector 130 detects tilt while the vehicle (V) is running and confirms the slope of the ground surface. The specific structure of the tilt detector 130 according to the present invention will be described in more detail below.

The altimeter 160 measures the altitude at which the vehicle V is currently located and allows comparison of whether the slope of the ground surface detected by the slope detector 130 matches the actual slope. Although the altitude does not change, the slope detector 130 It will be possible to identify ground structures such as speed bumps or entering a sidewalk from a roadway that recognize the slope.

The mileage confirmation device 180 checks the distance traveled by the vehicle (V) while interlocking with the mileage device 20 of the vehicle (V), and checks the mileage of the vehicle (V) while interlocking with the GNSS receiver 110. You may also be able to collect information about . Here, the mileage device 20 is a known and common device that is connected to the axle of the vehicle (V) and counts the number of rotations of the axle to estimate the moving distance of the vehicle (V). The accuracy of the measurement is not very high. Therefore, in order to collect more accurate information about the traveling distance, the driving distance confirmation device 180 may collect information about the moving distance from the GNSS receiver 110, as described above.

The signal transmitter 190 transmits a driving signal so that the reference coordinate transmitter 30 can transmit a reference signal toward the nearby vehicle V. The signal transmitter 190 and the reference coordinate transmitter 30 are applications of RFID (Radio-Frequency Identification) technology. The signal transmitter 190 and the control device 170 perform the function of an RFID reader and the reference coordinate transmitter ( 30) performs the function of an RFID tag. In addition, the present invention applies passive RFID technology that uses only the power of the reader part to operate the reference coordinate transmitter 30 that is always installed on the ground surface. Therefore, when a driving signal including a power source is transmitted from the signal transmitter 190, the reference coordinate transmitter 30 transmits a reference signal indicating that the slope of the relevant ground surface is 0 degrees, so that the control device 170 of the vehicle V Make sure you can receive it. For reference, it is preferable that the effective transmission radius of the reference signal is limited so that the vehicle V can accurately receive and recognize the reference signal at its location. In other words, if the vehicle (V) receives a reference signal and corrects it on a surface with a slope other than 0 degrees, errors will continue to occur in slope measurement on other surfaces, so the vehicle (V) and the reference coordinate transmitter 30 Effective communication must occur at a very close distance.

The control device 170 calculates the curvature state (slope) of the ground surface by combining the information confirmed by the slope detector 130, the altimeter 160, and the mileage confirmation device 180, and draws the final figure. The ground surface of Figure 1 may be expressed in the form of a graph such as Figure 4.

To explain this in more detail, the slope detector 130 measures the tilt angle (hereinafter 'slope') of the vehicle V in real time and transmits it as a detection signal to the control device 170, and the mileage confirmation device 180 ) checks the current driving distance of the vehicle (V) in real time and transmits it to the control device 170. The control device 170 displays the driving distance transmitted by the driving distance confirmation device 180 in real time and shows it as a slope transmitted by the slope detector 130 to complete a graph as shown in FIG. 4. At this time, even though there is a change in the slope transmitted by the slope sensor 130, if there is no change in the altitude information transmitted by the altimeter 160, it is a temporary change in slope due to an artificial structure formed on the ground surface, and the control device 170 determines the slope direction. You will be able to proceed to the aforementioned city without changing .

Ultimately, the control device 170 can precisely depict the curvature of the ground surface in relation to height (H) compared to distance (D), and accurately reflect this on the map to provide highly useful information to users.

Meanwhile, when the control device 170 receives a reference signal from the reference coordinate transmitter 30, it checks the inclination of the detection signal received from the inclination detector 130 to determine whether it is 0 degrees, and if not, detects the inclination detector ( An abnormal signal is output through the input/output device 150 so that the brake 134 of 130 can be released. Of course, when the operator confirms the abnormal signal output through the input/output device 150, he will release the brake 134 and reset the initialization of the tilt detector 130 at the corresponding position where the tilt is 0 degrees.

Figure 6 is a perspective view showing the tilt sensor according to an embodiment of the present invention, Figure 7 is an exploded perspective view of the tilt sensor according to an embodiment of the present invention, and Figure 8 is an embodiment of the present invention. This is a cross-sectional view showing the operation of the tilt sensor.

The slope sensor 130 according to the present invention is installed on the vehicle (V) to detect the slope of the ground surface on which the vehicle (V) passes, and includes a supporter (131) fixed to the body of the vehicle (V), and a supporter (131). ), a shaft 132 rotatably fixed to the shaft 132, a rotator 133 rotatably fixed to the supporter 131 via the shaft 132, and a brake ( 134).

The supporter 131 is not limited to the shape shown as long as it has a structure that can be fixed to the vehicle body while rotatably fixing the axle 132 in the shape of a circular bar, within the scope of the following claims. It may be implemented in various modifications.

As described above, the shaft 132 has a circular bar shape and is rotatably fixed to the supporter 131. The axle 132 may be configured with a bearing (not shown) for smooth rotation with the supporter 131, and a friction-lowering member may be applied to the circumferential surface to minimize friction with the supporter 131.

The rotator 133 includes a housing 133a having an arc-shaped hollow, a ring 133b for fixing the housing 133a to the shaft 132, and a plurality of pressure sensors disposed along the bottom surface of the hollow. (133c), a roller (133d) that presses the pressure sensor (133c) while moving along the hollow, and a pulley (133e) that is disposed along the ceiling surface of the hollow and facilitates the movement and rotation of the roller (133d) Includes.

The housing 133a has an arc-shaped hollow and is formed with a constant width so that the roller 133d can move. Here, the cylindrical roller 133d moves while rotating along the hollow, which causes a change in the lowest point of the hollow as the housing 133a tilts along the inclination of the vehicle V, and the roller ( This is because 133d) moves along the longitudinal direction of the hollow toward the lowest point.

The ring 133b fixes the housing 133a to the axle 132 and allows the housing 133a to rotate along the axle 132 that rotates with respect to the supporter 131. For reference, the housing 133a and the axle 132 are not limited to the fixing method using the ring 133b, but a method of forming the axle 132 and the housing 133a as one piece, or a separate method such as bolting or pins. Various methods may be applied, such as fixing using a fastening means.

A plurality of pressure sensors 133c are arranged in a row along the bottom surface of the hollow, detect the load of the roller 133d, and transmit the corresponding detection signal along with its ID to the control device 170. The pressure sensor 133c confirms the current position of the roller 133d so that the control device 170 can track the current posture of the housing 133a, and further determines the posture of the pivoter 133 and the vehicle V. By tracking the attitude of the vehicle (V), it is possible to track the slope of the ground surface where the vehicle (V) is located. For this purpose, the pressure sensors 133c are preferably arranged at a constant angle or at regular intervals along the bottom surface, and it is preferable that a large number of pressure sensors 133c are arranged closely for detailed measurement.

For reference, if the pressure sensors 133c are arranged in a row at 1-degree intervals, the control device 170, which sequentially receives detection signals from the pressure sensors 133c, recognizes that the rotator 133 is currently tilted by 1 degree. You will be able to do this, and through this, you will be able to track the exact inclination of the vehicle (V).

The roller 133d is rotatably fixed to the hollow while forming a cylindrical shape with a diameter corresponding to the width of the hollow, and is made of a material having sufficient weight to continuously apply a load to the pressure sensor 133c. Therefore, the roller 133d rolls toward the lowest point of the hollow along the inclination of the housing 133a and applies a load to the pressure sensor 133c located at the lowest point so that the pressure sensor 133c can detect it. do.

The pulley 133e is rotatably arranged in a row along the ceiling surface of the hollow, so that the roller 133d moving along the hollow can rotate and move smoothly without friction with the ceiling surface, and at the same time, the roller 133d While moving along the hollow, pressure is applied to accurately adhere to and pressurize the pressure sensor (133c). At this time, neighboring pulleys 133e are arranged to be spaced apart from each other to prevent mutual interference. Subsequently, the sheave 133e according to the present invention can be moved up and down on the ceiling surface of the housing 133a via a rotation axis (a; see Figure 9) in order to efficiently achieve close contact with the roller 133d. It is fixed. Therefore, the sheave 133e in direct contact with the roller 133d moves upward regardless of the posture of the housing 133a, as shown in FIG. 8, and the other sheaves 133e move downward by their own weight to reach the lowest point. It is located in

The brake 134 is fixed to the supporter 131 so as to be in close contact with the outer surface of the axle 132 and is operated by the input/output device 150. To explain this in more detail, the supporter 131 changes its inclination depending on the current posture of the vehicle V, while the pivoter 133 has an axle 132 rotatably fixed to the supporter 131. Maintain a horizontal posture at all times. That is, the position of the pivoter 133 is always fixed in the direction of gravity due to its own weight, regardless of the inclination of the supporter 131. However, when the vehicle V starts driving for geodetic survey work, the pivoter 133 must also be tilted according to the change in inclination of the supporter 131. To this end, during survey preparation, the brake 134 is released so that the rotator 133 can rotate smoothly independently from the supporter 131. When survey preparation is completed and a fixed signal for start is input from the input/output device 150, The brake 134 fixes the axle 132 so that the rotator 133 is restrained by the supporter 131.

The brake 134 according to the present invention may be applied by various means as long as it has a structure that can prevent the rotation of the axle 132. However, in the embodiment according to the present invention, the brake 134 is in close contact with the peripheral surface of the axle 132 and the axle 132 ) is installed on the supporter 131 while rotatably fixing the pad (134b) and a pad (134b) made of a material with a high friction coefficient that rotates according to the rotation of the It consists of a grabper 134a.

In the end, the field survey begins with the initial position of the roller 133d as shown in FIG. 8(a), and the vehicle V passes a road with the ground surface inclined at 'θ' as shown in FIG. 8(b). In this case, the rotator 133 will also be tilted by 'θ' and the roller 133d will be able to move by its own weight. Of course, the pressure sensor 133c detects the pressure caused by the movement of the roller 133d, and the detected signal is transmitted to the control device 170 in real time.

Meanwhile, the slope of the ground surface at the location where the vehicle V first starts may not be horizontal at 0 degrees. However, since the rotator 133 starts from a horizontal state regardless of the slope of the ground surface, the worker first measures the initial slope of the starting position and inputs it to the control device 170, and the control device 170 uses a pressure sensor. The detection signal transmitted from (133c) is corrected and processed based on the initial slope.

As described above, the vehicle V is tilted along the slope of the ground surface and the rotor 133 is also tilted, so the roller 133d sequentially presses the pressure sensor 133c while moving along the hollow, and the pressure sensor ( 133c) detects the pressure of the roller 133d and transmits the corresponding detection signal along with its ID to the control device 170, so that the control device 170 accurately calculates whether the vehicle V is tilted and the degree of tilt, Make it traceable. Of course, as described above, the control device 170 receives the mileage of the vehicle V confirmed by the mileage confirmation device 180 and displays a graph as shown in FIG. 4, through which the vehicle V The curvature of the ground surface traveled on can be shown.

Figure 9 is a cross-sectional view showing another operation of the tilt sensor according to an embodiment of the present invention.

Since the method of measuring the curvature of the ground surface according to the present invention is performed through a running vehicle (V), inertia can act on the roller (133d) while the vehicle (V) repeats stopping and driving, and through this, the curvature of the ground surface Regardless of the state, the roller 133d can move along the hollow of the housing 133a. Of course, this movement of the roller 133d pressurizes the pressure sensor 133c, and the pressure sensor 133c detects this and transmits it to the control device 170, so the control device 170 provides incorrect information about the ground surface. can be collected.

In order to solve this problem, the rotation shaft (a) that rotatably fixes the pulley (133e) is movably inserted into the moving groove (b) formed in the housing (133a), and the lower end of the moving groove (b) adjacent to the hollow Locking grooves (c) protruding opposite to each other are formed. Ultimately, the rotating shaft (a) moves along the moving groove (b) so that the pulley (133e) is pulled in and out of the hollow, and when receiving a lateral force from the roller (133d), the rotating shaft (a) moves into the locking groove (c). As it flows in, the sheave 133e is kept protruding into the hollow as shown in FIG. 8(a).

To explain this in more detail, the moving groove (b) is formed long along the circular diameter direction of the arc-shaped hollow. At this time, the rotating shaft (a) movably fixed to the moving groove (b) is spaced furthest from the hollow and maintains close engagement with the roller (133d) even when the sheave (133e) enters the hollow. Of course, on the contrary, if the rotation axis (a) is closest to the hollow and the sheave (133e) is pulled out into the hollow, the roller (133d) will be caught on the pulled sheave (133e) and its movement will be hindered.

Subsequently, a locking groove (c) protruding opposite to each other is formed at the bottom of the moving groove (b) adjacent to the hollow. As described above, the remaining sheaves, excluding the sheave 133e in contact with the roller 133d, move downward by their own weight and protrude into the hollow, and eventually the rotation axis (a) of the sheave is in the corresponding moving groove (b). It is located at the bottom. However, when the roller 133d, which has received inertia, moves along the hollow as the vehicle V stops or starts, the sheave receives a lateral force as shown in FIG. 9(a) by the roller 133d, and the lateral force The rotation axis (a) of the pulley that receives the flow flows into the locking groove (c). If the movement of the roller 133d continues in this state, the rotation of the roller 133d is transmitted to the sheave, and the sheave rotates in engagement with the rotation and further digs into the locking groove c, thereby moving the roller 133d. to stop Ultimately, the roller 133d is prevented from moving due to inertia and cannot leave its current position, and the control device 170 can always receive a constant detection signal.

On the other hand, in the case of normal movement of the roller 133d due to the inclination of the housing 133a, the roller 133d pushes up the sheave 133e from directly below, and the rotation axis a of the sheave 133e is connected to the locking groove c ), the roller 133d moves smoothly without interference as shown in FIG. 9(b) while moving upward to the moving groove (b) along the side of the roller (133d).
