Description

A level geodetic survey device capable of accurate surveying by checking whether an error has occurred in survey information {GEODETIC SURVEYING DEVICE TO MINIMIZIE ERROR}

The present invention relates to a geodetic survey device, and more particularly, by comparing the elevation information of a measurement point using a GPS and the elevation information of a measurement point measured using a surface and a level device to check whether an error has occurred, and to accurately measure It relates to a measuring device.

In general, geodetic surveying should be performed first for various civil engineering or architectural design. Geodetic survey refers to all activities in which horizontal distances, elevation differences, and directions are measured to determine the location of each measurement point, display them as drawings or figures, and stake out in the field.

Among these geodetic surveys, level surveying is a survey that calculates the height difference between two points using a surface scale and a leveler, and its accuracy is 5mm * S/2 for level 2 surveying (where S is a one-way distance and the unit is km. It is required to measure detailed enough to be specified within.

1 is a diagram illustrating a method of measuring a level using a conventional surface scale and a level device.

In the first step, the surface surface number (1) is set at the ground reference point (a0) where the altitude (altitude) is known, and the machine number is leveled from the first observation point (b1) a certain distance away. Read the scale of the surface scale (1) with a measuring device (2) such as a machine.

In the second step, the surface water moves to the first point (a1) to establish the surface scale (1), and the machine man changes the direction of the measuring device (2) such as a level at the observation point (b1) to measure a level, etc. Read the scale of the first point through the device (2). Here, the altitude of the first point is obtained from the difference between the scale read from the ground reference point (a0) and the first point (a1) and the altitude of the ground reference point.

In the third step, the number of machines moves to the second observation point (b2) behind the first point (a1), and the surface scale (1) changes its direction from its original position (point 1) so that the surface scale (1) is leveled. If you look at the measuring device (2) such as a machine, the machine man reads the surface scale of the first point (a1) with a level from the second observation point (b2).

In the fourth step, the surface water moves to the second point (a2) to establish the surface scale (1), and the mechanical number reads the surface scale of the second point (a2) from the second observation point (b2). Here, the altitude of the second point is obtained from the difference in scale between the first point (a1) and the second point (a2) read from the second observation point (b2).

In this way, while continuing to move the measuring instrument (2) such as the surface scale (1) and the level gauge (2), change the surface level of each point and the direction of the level device at each observation point, read the scale, and increase the altitude of each point to the target point. Seek.

At this time, according to the difference in elevation between the reference point (a0) at which the surface is built, or the first and second observation points (b1, b2) on which the first and second points (a1, a2) and the measuring device (2) such as a level gauge are mounted. It is necessary to adjust the height of the surface, and the conventional surface combines the upper and lower two chucks to be able to adjust the length in a slide type.

However, in the conventional geodetic surveying apparatus, when the scale is not accurately visible due to foreign substances such as dust on the surface of the surface, there is a problem in that it is inconvenient to clean the surface with a long surface water, and it is very difficult to wipe while holding the surface.

In addition, there is a problem in that efficient management is very difficult because it is not possible to comprehensively check the elevation (altitude) information measured through the geodetic survey device and the plane coordinates according to the elevation information.

Furthermore, in the conventional geodetic surveying device, when the surrounding vibration or impact is received during the geodetic survey, the level gauge or the surface scale is shaken in the process of reading the scale of the surface by a level device at a certain distance, making it impossible to accurately read the surface scale. Accordingly, there is a problem in that a measurement error occurs.

2 is an exemplary diagram of a level geodetic survey device capable of accurate surveying by checking whether an error occurs in survey information according to an embodiment of the present invention, and FIG. 3 is a view showing a part of a measuring device according to an embodiment of the present invention. 4 is a view showing the state of the lifting motor according to an embodiment of the present invention, Figure 5 is a view showing the state of the angle adjusting motor according to an embodiment of the present invention.

As shown, the geodetic survey device according to the present invention includes a measuring device 100 for oscillating a laser, a target 400 for the laser oscillated by the measuring device 100, and the measuring device 100 and the target It includes a main server 500 for transmitting and receiving and controlling data related to the measurement and measurement of 400.

At this time, the measuring device 100 includes a water tank 110, a fixing column 120 fixed to the center of the water tank 110, a flow column 130 assembled to the fixing column 120, and the flow column The rotating pillar 140 assembled on the upper end of the 130, the laser fixing box 150 fixed to the rotating pillar 140, and the laser fixing box 150 are installed so that the angle can be adjusted in the vertical direction. It includes a laser oscillator 160.

Here, the water tank 110 is a cylindrical shape with an open top, as in the example of FIGS. 2 and 3, a cylindrical boss 112 is formed in the inner center, the outer peripheral surface of the boss 112 and the water tank A storage space 114 is formed between the inner circumferential surfaces of (110). The storage space 114 is used while being filled with water to a certain level.

In addition, the fixing column 120 is formed in a cylindrical shape with open upper and lower ends, and the lower end is screwed to the boss 112.

In addition, an elevating motor 200 as shown in FIG. 4 is built into the fixed pillar 120, and the motor shaft 210 of the elevating motor 200 protrudes up and down of the elevating motor 200, and the motor shaft The inside of the 210 is hollow, and the ball screw BS is screwed through it.

In particular, motor fixing devices 220 are further provided on both sides of the elevation motor 200 to be configured to fix the elevation motor 200 in the fixing column 120, and both sides of the elevation motor 200 are not provided. Guide bars (GB) are arranged in the space.

In addition, a stopper 122 is assembled at the open top of the fixing column 120, and a central through hole 122a through which the ball screw BS passes is formed in the center of the stopper 122, and the central through hole A pair of guide holes 122b are formed to be symmetrical in the radial direction at intervals from 122a, so that the guide bar GB can pass therethrough.

In addition, the upper end of the ball screw BS is rotatably connected to the center of the lower surface of the flow column 130, and the guide bar GB is also fixed to the lower surface of the flow column 130.

And a first controller (RC1) including a remote control receiver is provided on the outer surface of the fixed pillar 120, and a remote control (CON) for wirelessly controlling the driving of the lifting motor 200 through the first controller (RC1) Is prepared.

Accordingly, by controlling the rotation direction of the lifting motor 200 through the first controller RC1, the height can be adjusted while lifting the floating column 130 with respect to the fixed column 120.

On the other hand, as shown in FIG. 2, a shaft groove (not shown) is formed on the upper surface of the flow column 130, and a lower shaft 142 protruding from the lower surface of the rotary column 140 is inserted into the shaft groove. (BA) By being combined, the rotating pillar 140 is configured to rotate smoothly.

At this time, a tooth shape is formed on the circumferential surface of the lower end of the rotating column 140 to constitute a driven gear 144, and a driving gear 146 is tooth-coupled to the driven gear 144, and the driving gear 146 is It is connected to the rotation motor 148, and the rotation motor 148 is fixed to the outer peripheral surface of the flow column 130.

Therefore, by controlling the rotation motor 148, the rotation angle of the rotation column 140 in the horizontal direction can be adjusted.

In this case, the control of the rotating motor 148 is performed by the first controller RC1, and the flow column 130 is raised and lowered, but it is not rotated. A battery can be used, but it is not shown as it is a general matter.

In addition, a laser fixing box 150 is fixed to an upper end of the rotating pillar 140, and a laser installation groove 152 open to a predetermined size is formed on one side of the laser fixing box 150, and the laser installation groove A laser 160 that can be angled up and down is installed at 152, a laser communication antenna 154 is installed on an outer surface of one side of the laser fixing box 150, and a second controller RC2 is installed at the lower side thereof. .

In addition, a marker (MK) is installed on a part of the outer surface of the laser 160, and a marker detection sensor (SN) is located in the center of the laser installation groove 152, precisely at a point where the laser 160 is kept horizontally. Is installed and configured to transmit a detection signal to the second controller RC2.

At this time, when the marker detection sensor SN detects, the second controller RC2 reads that the laser 160 is located in the home position and uses it as a reference point when measuring the angle.

Therefore, if the angle of the laser 160 changes, the second controller RC2 can calculate what angle has changed from the reference point, which is rotated by the encoder provided in the angle adjusting motor 300 (see FIG. 5) to be described later. By reading the number, the arithmetic unit mounted on the second controller RC2 is calculated through the changed distance from the reference point to calculate the angle.

In addition, the calculated angle information is wirelessly communicated through the laser communication antenna 154 and transmitted to the main server 500.

Here, the angle control motor 300 includes a reducer 310 coupled to a rotation shaft protruding to both sides, and the output shaft 320 of the reducer 310 is fixed to the shaft fixing tool 330, and the shaft fixing tool 330 penetrates through both side surfaces of the laser fixing box 150 and is firmly fixed.

Therefore, when the angle adjusting motor 300 is driven, since the output shaft 320 is fixed to the shaft fixing tool 330, the angle adjusting motor 300 rotates to adjust the angle of the laser 160.

Accordingly, the laser 160 is fixedly installed on the outer surface of the angle adjusting motor 300, and the angle adjusting motor 300 includes a motor battery BT and the second controller RC2 so that their own power can be used. ) And a wireless communication module (NFC) capable of short-range wireless communication is provided.

In addition, an ultrasonic receiver WS capable of oscillating and receiving ultrasonic waves is further installed at a lower vertex of the outer peripheral surface of the laser 160, which is connected to and controlled by the second controller RC2.

At this time, the ultrasonic wave receiver (WS) is to double the horizontality of the laser 160, i.e., the origin control, to check the correct horizontality to enable precise measurement without errors. This is a very small error due to the nature of the straight laser beam. This is because Rado changes into a large error when measuring a long distance.

To this end, by filling the storage space 114 of the water tank 110 with water at a certain level and checking whether there is a height difference using an ultrasonic wave receiver (WS), rotate the rotating pillar 140 at least at three points. The purpose is to measure the height through time difference according to the reception after the ultrasonic oscillation, so that the horizontality of the laser 160, that is, the zero point, can be adjusted according to whether or not they match at three points. Of course, the correct zero point adjustment is completed by the marker (MK) and the marker detection sensor (SN), but since it may be distorted during use, a zero point adjustment function using ultrasonic oscillation is included to correct this.

Since this is always the same in the case of sleep, even if the position of the ultrasonic receiver (WS) is measured at least three points differently using this principle, if the same value comes out, the zero point is adjusted, that is, the horizontality is completely aligned. If a different value appears, the horizontality is bad and needs to be corrected.

In this way, more accurate measurement is possible by making the leveling adjustment itself redundant.

On the other hand, the surface flag 400 is made of a surface pillar 410 that is embedded in the ground and a surface plate 420 in the shape of a square plate fixed to an upper end of the surface pillar 410.

At this time, since a scale is displayed on the surface column 410, care should be taken to be embedded at the same depth when measuring the elevation of the reference point and the elevation of the measuring point.

Of course, if the depth correction function is provided, it can be mounted freely, but the depth correction function is omitted in the present invention.

In addition, a surface hole 422 is formed in a predetermined size at the center of the surface plate 420 so that the laser beam oscillated from the laser 160 can be received, and a photodiode on the rear surface of the surface hole 422 A 424 is provided in the form of being embedded in the surface plate 420, and the photodiode 424 is connected to the control board 430 embedded in the surface plate 420 and controlled.

Here, the control board 430 is a PCB board on which a main control unit (MCU) is mounted, and when a laser beam is received through the photodiode 424, it is detected to confirm that the laser beam has been accurately received, and the laser 160 ), the distance from the laser 160 to the surface plate 420 is calculated by using the time taken to receive light and the speed of the laser beam.

To this end, the moment the laser beam is oscillated from the laser 160, the time information is transmitted to the main server 500 through the second controller (RC2), and the main server 500 transmits the time information to the surface plate 420 It transmits to the control board 430 of, and the control board 430 calculates the time taken by comparing the received time information with the time information at the time of receiving light.

At this time, various types of information may be stored and utilized in a memory mounted on the control board 430.

Accordingly, the target plate 420 includes a target communication antenna 440 capable of wireless communication with the main server 500, and also includes a GPS antenna 450 to communicate with GPS.

In addition, a display 460 may be further provided on the front surface of the surface plate 420 to display distance information, coordinate information, and elevation information corresponding to coordinates.

In particular, since the control board 430 is equipped with a GPS module, coordinate information is received through GPS communication and transmitted to the main server 500, and the main server 500 is preset corresponding to the received coordinate information. The elevation information is transmitted to the surface plate 420.

Therefore, it is possible to check the error by comparing the elevation information measured using the surface indicator 400 and the measuring device 100 with the elevation information checked through GPS, and finally confirm whether the error is due to a change in the terrain, and stored information Value can be corrected.

This invention can be geodetic surveyed through the following process.

First, the surface surface plate 420 is set up at the ground reference point where the surface surface water is known at the altitude, and the machine man oscillates a laser beam from the laser 160 of the measuring device 100 at the first observation point at a certain distance to the surface surface hole 422 Matches with

At this time, since it is a centering operation that matches the surface hole 422, distance calculation is not required.

In this way, when the laser beam is accurately incident on the surface hole 422, the laser 160 stops oscillation and starts a surveying operation.

Then, the time value at the moment when the laser beam is oscillated is transmitted to the main server 500, and when the laser beam is oscillated and reaches the surface hole 422, the arrival time is calculated and the control board provided on the surface plate 420 At 430, the distance between the surface plate 420 and the laser 160 can be known. Of course, the elevation of the ground reference point is known at this time.

Subsequently, the surface water moves to the first point and the surface plate 420 is re-established, but the same depth as the planted at the ground reference point is maintained, and the laser 160 is centered again.

At this time, since the angle change occurs, the vertical and horizontal rotation of the laser 160 is performed.

Since the angle change generated in this process is calculated by the second controller RC2, this angle information is also transmitted to the control board 430 of the front plate 420 through the main server 500.

Therefore, since the MCU of the control board 430 knows the distance information for the ground reference point and has received the angle information, it is possible to know the height information for the first point, that is, the relative elevation of the ground reference point by trigonometry.

In addition, the coordinate information for the first point and the previously stored elevation information for that point are received from the main server 500 through GPS communication and compared with the measured elevation information, and the difference is checked to accurately diagnose the error. If there is no error, accurate surveying has been made, and if there is an error, it can be managed by checking whether it is a mechanical defect or a change in terrain, and correcting the previously stored elevation information.

When configured in this way, it is not necessary to read the surface scale scale individually, reducing the possibility of error, and accurate measurement is possible.

Meanwhile, as shown in FIG. 3 and the like, the buffer unit 700 is coupled to the lower surface of the water tank 110 of the measuring instrument 100 to prevent the measuring instrument 100 from shaking due to external shock or vibration.

The buffer unit 700 includes a buffer top plate 710 disposed under the water tank 110, a buffer bottom plate 730 disposed at a predetermined distance below the buffer top plate, and between the buffer top plate and the buffer bottom plate. It is mounted on and includes a buffer elastic portion 720 for providing an elastic restoring force in the vertical direction.

In the illustrated embodiment, the buffer upper plate 710 and the buffer lower plate 730 are formed in the shape of a square panel, but are not limited thereto, and may be formed in various shapes, and the buffer elastic part 720 is also a coil spring. It is formed in a shape, but is not limited thereto.

The cushioning elastic part 720 attenuates the shock or vibration applied to the measuring device 100 from the ground by providing an elastic restoring force in the vertical direction, thereby improving the accuracy of the geodetic survey operation.

In addition, four upper plate extensions 711 forming a'U'-shaped groove are protruded toward the bottom at four corners of the buffer upper plate 710, and a'U'-shaped groove is provided at the four corners of the buffer lower plate 730. Four lower plate extensions 731 forming a protrude extend toward the top.

That is, the upper plate extension part 711 and the lower plate extension part 731 are formed to protrude to face each other like a tooth, and the upper plate extension part 711 is disposed relatively inside the lower plate extension part 731, so that the upper plate extension part ( A predetermined space is formed in a portion where 711 and the lower plate extension 731 face each other.

The left and right elastic parts 740 are inserted in a predetermined space formed by the upper plate extension part 711 and the lower plate extension part 731. The left and right elastic parts 740 have one side in contact with the'U'-shaped groove of the upper plate extension 711 and the other side with the'U'-shaped groove of the lower plate extension 731 to buffer the buffer upper plate 710 Elastic restoring force is provided to the lower plate 730 in the front and rear, left and right directions.

In other words, the buffer top plate 710 and the leveler 200 or the support member 400 coupled thereto is attenuated in the vertical direction by the buffer elastic portion 720, and the left and right elastic portions 740 Vibration in the front and rear directions is attenuated.

On the other hand, as shown in FIG. 7, of the four upper plate extensions 711, the two upper plate extensions 711, which are disposed on one side of the buffer top plate 710, and the four upper plate extensions 711, the buffer top plate 710 ) Between the remaining two upper plate extension portions 711 disposed on the other side of the upper plate are connected through the upper plate support portions 712, respectively.

The upper plate support part 712 and the lower buffer plate 730 are connected through a height fixing part 750, and as the height fixing part 750 is adjusted, the separation distance between the buffer upper plate 710 and the buffer lower plate 730 is variable. Can be.

That is, the user can tighten or loosen the height fixing unit 750 in consideration of the condition of the road surface to perform geodetic surveying, the weight of each measuring device, etc., and accordingly, between the buffer upper plate 710 and the buffer lower plate 730 Since the separation distance is varied, the rigidity of the buffer elastic part 720 may be adjusted.

In this case, it is preferable that the distance between the lower surface of the buffer upper plate 710 and the uppermost end of the lower plate extension part 731 be adjusted to be relatively narrower than the length of the left and right elastic parts 740.
