Description

DETAILED DESCRIPTION OF THE INVENTION Conventional alidators for flat surveying use a method of creating a drawing by sighting the target direction and plotting distance measurements with a tape measure on the drawing according to the scale.

However, at this time, it was extremely difficult to plot the correct measurement points on the map due to misreading of the scale or unfamiliarity with the plotting technique, and a highly skilled surveyor was required.

In order to eliminate such defects, the present invention Aridart slides the moving plot needle linearly in a groove in the base, which plots measurement points on the target direction line on the diagram, and converts the amount of movement of the moving plot needle into a digital electrical signal using an encoder. The purpose of the present invention is to provide an arid dart which is characterized by converting the data into a digital image and displaying it, as well as giving a scale using a switch and directly displaying the amount of movement digitally.

The Alidart of the present invention will be explained with reference to the drawings as follows.

1, 2, and 3, a straight groove 3 is provided on one side of the upper surface of the base 2 of the main body 1, and a linear groove 3 is provided in this groove at both ends of the lower part of the sliding platform 4 of the moving proto needle 6. The two pins 5, 5' are slidably connected to each other so that they can move linearly along the linear groove.

At the inner end of the slide 4, there is a belt 8 that is hung around two pulleys 7, 7' provided inside the base.
The sliding base of the moving prot needle is connected to the slide plate of the moving prot needle via the mounting bracket 9, and the pulley 7
The rotary encoder 14 directly connected to the rotary encoder 14 is rotated, and the encoder output is sent to the digital display board 1 by means of a printed circuit board 10 having a counter and a scale calculation circuit.
Display it on 1. The moving plot needle 6 first moves to zero point A.
The reset switch 12 is pressed to set the display to zero, the given scale value is selected by the scale switch 13, and the distance is measured by the optical distance meter 30 on the pole ₂₉ set at the target point P2 shown in FIG. .
The measured distance value is received by transceivers 33, 33', etc.
The moving plot needle 6 is moved and plotted until this distance value matches the numerical value displayed on the display window 11.

There is a zero point plot needle 15 at the zero point A, and the zero point is plotted in advance, but as mentioned above, when aligning the moving plot needle 6 to the zero point, the rotation axis 1
6 as an axis and avoid the zero point plot needle in the direction of the arrow.

The collimating telescope 18 has a ruler 17 at one end of the horizontal axis 19.
It is mounted directly above the machine so that it can rotate freely in the vertical direction.

As shown in FIG. 4, a rotary arm 20 is fixed to the other end of the horizontal shaft 19, and the altitude angle can be successively read using an indicator 22 on the scale of an altitude scale plate 21 provided at the bottom. Also, there is a fixing device 23 on the outside of the rotating arm, and a fixing screw 26 and fine movement devices 24, 25.
The collimating telescope 18 can be fixed and slightly moved in any altitude angle direction.

Furthermore, 27 on the main body 1 in Fig. 1 is a circular bubble tube;
8 is a battery for driving all the electric circuits of this device.

As shown in FIG.
When used in conjunction with the measurement point _p1 , place a flat plate on the measurement base point p1, place the main body 1 on it, and place the pole 29 with the optical distance meter 30 attached on the top on the target point _p2 .
This optical distance meter can be used to sight the corner prism 31, which is removably attached to the collimating telescope of the main body 1 by means of a support fitting 32, and measure the distance L between two points.

As explained above, when using the inventive Alidart, when the observer moves the moving plot needle without using the conventional scale on the ruler pointing in the collimation direction, the plot position is automatically adjusted according to the selected scale. This completely eliminates plot errors and misidentification of scales, allowing even inexperienced users to perform accurate measurements, and eliminating the need to prepare or replace a replacement scale that was previously selected depending on the scale used. All you need to do is just flip a switch. It goes without saying that there will be no problem even if the Aridart of the present invention is used in conjunction with a light wave distance meter and a conventional tape measure is used for distance measurement.

Furthermore, conventional flat plate surveying requires a highly skilled engineer on the flat plate side and an assistant on the pole side, but when using the present invention ARIDATO, there is no need for an engineer on the flat plate side, and an engineer is required on the target point side. Since the survey work can be carried out while making comprehensive judgments on the survey, it is possible to not only perform high-quality surveys, but also prevent re-measurements and increase survey efficiency, which is an innovative method that greatly reduces survey costs. This is what we provide.
