In this case, the distance sensor 232 may be provided as an infrared or ultrasonic sensor, but it is preferable that the distance sensor 232 is provided as a laser sensor so as to visually confirm that the movable tool 230 is located on an extension line of the measurement target position. .

Hereinafter, the operation method for the pole 200 of the surveying device having an automatic control function according to the present invention configured as described above will be described in more detail.

First, the operator places the reference pole 210 on a flat surface adjacent to the measurement target position, and operates the control switch provided in the fixture 220 to move the movable tool 230 on the upper extension line of the measurement target position.

In other words, when the motor is operated by the operation of the control switch, while the pinion (P) is rotated, the slide bar 242 slides to move the moving port 230 (left side in FIG. 2).

At this time, the movable tool 230 is moved away from the ground of the measurement target position by a certain height, it is difficult to determine whether the movable tool 230 is accurately positioned on the upper extension line of the measurement target position.

Therefore, before moving the movable tool 230, the distance sensor 232, preferably a laser sensor installed in the lower portion of the movable tool 230 is operated.

The laser sensor is composed of an output module for outputting a laser and a receiving module that receives the output laser is reflected, when operating the laser sensor as described above, the laser point is displayed on the ground of the measurement target position, Visually confirm this to operate the control switch so that the movable port 230 is accurately positioned on the upper extension line of the measurement target position.

When the movable tool 230 is located on the upper extension line of the measurement target position as described above, the operator observes the measuring pole 231 provided on the upper portion of the movable tool 230 by using the measuring tool 100. The measurement target position is calculated.

On the other hand, in order to measure the height such as the altitude above sea level, it is necessary to measure the height from the measurement target position to the moving tool 230.

To this end, the fixture 220 according to the present invention, as shown in Figure 4, the input unit 221, the data processing unit 222, the measurement request unit 223, the result receiving unit 224 and the display 225 is configured .

The input unit 221 is provided with a height measurement button (not shown) including the above-described control switch, when the operator selects the height measurement button, the input unit 221 outputs a distance sensing request signal to the data processor 222. Is sent to.

When the distance sensor request signal is input, the data processor 222 transmits a measurement request signal to the measurement signal transmitter 232a of the distance sensor 232 through the measurement request unit 223, and the distance sensor 232. The detection signal received by the measurement signal receiver 232b of through the result receiving unit 224 is received.

Here, the measurement request unit 223 and the measurement signal transmitter 232a, the result receiver 224 and the measurement signal receiver 232b are electrically connected to each other, preferably the horizontal port 240 shown in FIG. ) Is wired to the inside.

When the detection signal is received as described above, the data processor 222 calculates the time until the time point at which the laser transmitted from the measurement signal transmitter 232a is received by the measurement signal receiver 232b, and half of the value multiplied by the luminous flux. It is calculated as the distance from the moving port 230 to the measurement target position.

Here, the distance calculation method may be variously modified according to the needs of those skilled in the art according to the reference and the type and function of the distance sensor 232 to be measured.

In addition, the distance from the movable tool 230 calculated as described above to the measurement target position is output through the display 225 installed in the fixture 220, so that the operator can easily check.

On the other hand, in using the pole 200 according to the present invention as described above, for more accurate measurement, it is preferable to control so that the measurement sphere 100 is not inclined.

To this end, as shown in FIG. 3, a horizontal control tool 130 for correcting the inclination of the surveying mirror 110 is provided between the surveying mirror 110 and the tripod 120 of the measuring tool 100. do.

Here, reference numeral '111' is an eyepiece, '112' is an objective lens, and '113' is a body.

The horizontal control unit 130, the lower plate 131 is fixed to the upper portion of the tripod 120, the upper plate 132 and the lower plate 131 is fixed to the lower side of the surveying mirror 110. Is fixedly configured to include a horizontal control module 133 to control the horizontal of the upper plate 132.

In addition, the horizontal control module 133 is installed on one side of the upper plate 132, a horizontal sensor (not shown) for detecting the inclination of the upper plate 132 and the detection signal of the horizontal sensor And a horizontal control unit (not shown) for outputting a control signal for controlling the horizontality of the upper plate 132 and a six-axis driving unit for receiving and operating the control signal.

In other words, when the horizontal sensor detects the inclination of the upper plate 132, the horizontal control unit analyzes this, and then outputs a control signal for the upper plate 132 to be horizontal, and the output control signal is a six-axis drive unit 6, the six-axis driving unit is operated in response to the control signal, the horizontal of the upper plate 132 is corrected.

Here, the horizontal sensor and the six-axis drive unit can be modified and replaced with various ones according to the needs of those skilled in the art.

For example, the six-axis drive unit is to move and rotate about the X-axis, Y-axis and Z-axis, and according to the needs of those skilled in the art Of course it is possible.

5 and 6 show another example of a pole of a surveying apparatus having an automatic control function according to the present invention. In describing FIGS. 5 and 6, the detailed description of the overlapping configuration described above will be repeated. Not surprisingly.

Looking at this in detail, first, the distance calculation to calculate the distance (height) between the mobile device 230 and the ground through the distance sensor 232 inside the mobile device provided with the distance sensor 232. The unit 233 is mounted, and the height calculated by the distance calculating unit 233 is output to the outside through the output unit 234 provided on one side of the moving port 230.

When the height of the movable port 230 is output through the output unit 234 as described above, the operator using the measuring instrument 100 only through the surveying mirror 110 to check the position of the measurement target position. The relative height will be known.

At this time, the data processing unit 222 of the fixture 220 shown in Figure 6, does not perform a separate height calculation operation, the height information transmitted from the distance calculation unit 233 of the mobile device 230 (of the calculated height Value) is transmitted to the display 225 to be output to the outside.

On the other hand, in surveying the measurement target position by using a surveying device having an automatic control function according to the present invention as described above, when the reference pole 210 is inclined due to a mistake of the operator, the distance detection of the movable tool 230 The case where the point where the sensor 232 is reflected (point indicated) is deviated from the measurement target position occurs.

If the measurement target position is hidden from the operator who positions the reference pole 210, the operator can not check the error according to the inclination of the reference pole 210, it is not possible to adjust the inclination of the reference pole 210 In this state, if the measurement proceeds, the measurement target position cannot be measured accurately.

Therefore, it is necessary for the operator who positions the reference pole 210 to more easily check whether the distance sensor 232 correctly indicates the measurement target position.

To this end, in the present invention, as shown in Figures 5 and 6, the camera 235 is installed on one side of the moving port 230, the image photographed through the camera 235 is the distance calculation unit 233 and By transmitting the result receiver 224 to the data processor 222 and outputting the captured image to the display 225 by the data processor 222, an operator who positions the reference pole 210 displays the display 225. By correcting the position and the tilt of the reference pole 210, the distance sensor 232 can be adjusted to accurately indicate the measurement target position.

Here, in order to facilitate the correction of the operator to position the reference pole 210, in the present invention, as shown in Figure 5, the moving sphere 230 is two orthogonal to each other by the two-axis hinge (250) It is preferable to be installed in the horizontal transfer port 240 so as to be hinged about the axis.

Since the detailed configuration of the biaxial hinge 250 as described above can be variously changed according to the needs of those skilled in the art, it is obvious that the present invention is not limited to a specific one. In the present invention, referring to FIG. Let's look at an example.

The biaxial hinge 250 includes a first hinge connector 251 to which the movable tool 230 is hinged, and a second hinge connector 252 to which the first hinge connector 251 is hinged. The second hinge connector 252 is fixedly installed on the slide bar 242 of the horizontal port (240).

Meanwhile, when the first hinge connector 251 and the second hinge connector 252 are hinged, excessive rotation in one direction may occur due to the weight of the movable tool 230.

Therefore, the first hinge connector 251 is provided with a weight 251a corresponding to the weight of the movable tool 230 on the opposite side of the movable tool 230, so that the distance sensor 232 of the movable tool 230 is always Direct the Earth's gravity direction.

Therefore, by the above process, by adding a function that can move in the horizontal direction with respect to the pole 200, by allowing the automatic correction for the horizontal tilt with respect to the surveying instrument 100, It is easy to measure even points that are difficult to measure, such as not secured or sloped.

The surveying apparatus having an automatic control function according to the present invention has been described above. Such a technical configuration of the present invention will be understood by those skilled in the art that the present invention may be implemented in other specific forms without changing the technical spirit or essential features of the present invention.
