DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

For reference, leveling is a measurement to measure the difference between the high and low points and the elevation of sea level. Generally, the level of the telescope and the level are combined and the height of the point is determined using the scale. Leveling is used for designing and construction of roads, rivers and canals, calculation of excavation volume, topographic map showing the shape of the terrain, and national level point surveying. Leveling can be divided into direct leveling, indirect leveling, reciprocal leveling, and approximate leveling according to the survey method.

For accurate leveling, direct leveling methods are used, where the digital staff for leveling, indicated by bar codes, is used.

1 is a perspective view showing a digital staff height adjustment device for surface level measurement for measuring the distance between the terrain according to the present invention, Figure 2 is a digital staff height control for ground level measurement for measuring the distance between the terrain according to the present invention. As a separate perspective view of the device, the staff of the present invention comprises a staff body and a staff cover.

The staff body is engraved (engraved) or printed with a reference scale barcode arranged at regular intervals in the vertical direction and a detailed scale barcode arranged at regular intervals smaller than the reference scale barcode. Or attached. As the method of attaching, a transparent or translucent label can be used.

In the attached drawings, a detailed scale barcode is marked with a scale in order not to complicate the drawing, but it is very natural that the barcode is displayed.

On both sides of the star main body, recesses are formed at the same height as the reference scale bar code, and a handle is provided on the front side to allow the user to carry it.

In the star cover, convex portions convex inward to correspond to the concave portions are formed at the same height as the reference scale bar code. The height of the stiff body is adjusted by inserting the stiff body into the convex portion of the stiff cover at a desired height.

Referring to the attached drawings, the staff 11 includes a reference scale barcode 14 arranged or arranged at regular intervals and a detailed scale barcode 15 arranged or arranged at a smaller interval than the reference scale barcode 14 ) Are displayed. These graduations are preferably formed by dicing a conventional star scale into grooves, and may be directly printed or printed with a transparent or semi-transparent material.

In this case, the reference scale barcode 14 is a scale set for height adjustment and leveling of geodetic surveying, and it may be an arbitrary interval for adjusting the height of a staff member. Cm < / RTI > and so on.

On both side surfaces of the star main body 11 are formed concave recesses 132 formed at intervals of the reference graduation bar codes 14 and on both sides of the star cover 12 so as to correspond to the recess portions 132, And convex convex portions 131 formed at intervals of the bar codes 14.

A handle 16 is provided on the front surface of the star main body 11 to allow the user to hold the concave and convex portions 13 formed by the convex portion 131 and the concave portion 132 with the hand.

At this time, the convex portion 131 is preferably made of a material having a sticky (viscous or viscous) or frictional material such as rubber or synthetic resin so as not to be easily detached when the concave portion 132 is engaged with the concave portion 132.

Therefore, the user can pull the handle 16 to release the engagement of the concave and convex portions 13, and hold the concave and convex portions 13 with the handle 16, thereby joining the concave and convex portions 13 together.

3 and 4 are front views showing the use of the digital staff height adjustment device for ground level measurement for measuring the distance between the terrain according to the present invention, by moving the staff combined in the state of FIG. The height can be adjusted, and the corresponding reference scale barcode is 2 spaces, so it is necessary to add the height corresponding to the two reference scale barcodes to the measured scale to measure the final value.

That is, even if 150 centimeters are measured by the staff body 11, since the reference scale barcode is increased by two spaces in the state of FIG. 4, for example, if the reference scale barcode is 1 centimeter, two centimeters are added to 150 centimeters to measure the final measured value (measurement value). Is determined by

FIG. 5 is a side view illustrating a case in which the height is adjusted using a digital staff height adjusting device for ground level measurement, which measures the distance between the terrain according to the present invention. The numerical values corresponding to 1, 2, 3, etc. can be used for convenience of measurement (measurement).

LED staff, battery and switch inside the staff body 11 so that the digital staff height control device for surface level measurement, which measures the distance between the terrains as described above, can accurately measure the scale even when it is dark to identify at night or in rainy weather. Can be installed, which is illustrated in more detail.

As shown in FIG. 6, the material of the staff body 11 is formed of a transparent or translucent material, and light emitting means is installed therein. Using a translucent material can more clearly identify the level indicated by the diffuse reflection of light.

That is, a space for accommodating the light emitting means is provided in the transparent or translucent staff main body 11, and is installed to be detachably attached to the cover 24, and a battery 23 is provided on the inner surface of the cover 24. In addition, the substrate 26 on which the plurality of LEDs 27 are mounted is fixed to the space. Since it is not always surveyed or always dark, the staff main body 11 is provided with a switch 21 for turning on and off the power supplied from the battery 23 to the LED 27. For electrical connection, an electrode 22 having contact with the battery 23 and having elasticity is fixed to an inner wall of the space to be accommodated, and one end of the switch 21 is connected to the electrode 22 by a cable 25. The other end of the switch 21 is connected to the LED 27 and the cable 25.

That is, while the battery 23 is mounted, one electrode is electrically connected to one electrode of the substrate 26, and the other electrode of the battery 23 is connected to one end of the switch 21 through the electrode 22 and the cable 25. The other end of the switch 21 is connected to the other electrode of the substrate 26 through the cable 25.

At this time, the LED 26 is installed on the substrate 26, one electrode of the LED (27) is electrically connected to one electrode of the substrate 26 and the other electrode of the LED (27) is a substrate ( 26) is connected to the other electrode.

Therefore, when the switch 21 is pressed or set to an on state, the battery 23 is electrically connected to the LED 27 through the electrode 22, the cable 25, and the switch 21. Is supplied to the power source, and the LED 27 is turned on, and the staff body 11 is transparent or translucent as described above, so that the light shines brightly until the scale, and the level measurement worker Graduation can be easily measured even in dark or invisible situations.

On the other hand, when the staff 10 is not used or in a place where the environment is bright, the switch 21 is set to an off state, so that the battery power is blocked from being supplied to the LED 27.
