Description

[Detailed description of the invention] (Technical field of invention) The present invention relates to a surveying instrument having distance measurement and angle measurement functions.

(Background of the Invention) This type of surveying instrument includes a distance measuring device that outputs a distance measurement signal and a horizontal angle measuring device that outputs a horizontal angle signal.

Conventionally, in order to conduct a traverse survey using this type of surveying instrument, a measuring point P is required. Set the surveying instrument to measurement point P. Input the coordinate value XO+YOLZO using a key switch, etc., and preset the horizontal angle measuring device so that the reference direction of the reference telescope matches the magnetic north NK and the horizontal angle signal becomes zero. After presetting the altitude angle measuring device so that the direction coincides with the zenith and the zenith angle signal becomes zero, the target point P1 is referenced. At this time, the distance value SD to the target point P1 based on the ranging signal obtained from the ranging device, the horizontal angle αD based on the horizontal angle signal obtained from the horizontal angle measuring device, and the altitude angle signal obtained from the altitude angle measuring device The relative coordinate XI of the target point P1 is determined by the altitude angle βD and the above-mentioned coordinate value X0IYO+ZO.

After presetting the altitude angle measuring device so that the direction coincides with the zenith and the altitude angle signal becomes zero, the measurement point P is determined (the horizontal angle measurement direction is always set clockwise). The horizontal angle according to the horizontal angle signal of this next horizontal angle measuring device is α+
Confirm that it is 180 degrees and standardize the new target point counterclockwise. The horizontal angle signal of the horizontal angle measuring device at this time indicates the horizontal angle αxk of the new target point. Then, this horizontal angle α2, the altitude angle β1 based on the altitude angle signal obtained from the altitude angle measuring device, the distance measurement value S1s based on the distance measurement signal obtained from the distance measuring device, and the coordinates X1 of the new measurement point P1.

By the way, in such a conventional surveying instrument, the distance Sns to the target point at the measurement point is the horizontal angle αn.

The altitude angle βn is measured to find the coordinates of the target point, a surveying instrument is installed at the target point, and this is used as a new measurement point to standardize other target points, but the horizontal position of the surveying instrument is Since it generally changes, it was necessary to preset the horizontal angle measuring device so that the reference direction coincides with the magnetic constant N again so that the horizontal angle signal indicates a horizontal angle of zero. Then, the survey instrument was rotated clockwise to standardize the old measurement point, and the horizontal angle signal was (α+180 degrees).

Alternatively, after setting the target point, fix the scale disk of the horizontal angle measuring device and move it to the target point, then release the fixation of the scale disk and rotate it 180 degrees clockwise so that the old measurement point can be referenced. is doing.

The above explanation was based on the clockwise rotation standard, but the same applies to the counterclockwise rotation standard.

(Object of the Invention) The object of the present invention is to provide a surveying instrument that solves the above-mentioned drawbacks and improves operability in polygonal surveying.

(Example) The present invention will be described below based on the example shown in the drawings.

The surveying instrument includes a distance measuring device 1 that outputs a distance measurement signal, a horizontal angle measuring device (for example, a photoelectric rotary encoder) 2 that outputs a horizontal angle signal, and an altitude angle measuring device (for example, a photoelectric rotary encoder) that outputs an altitude angle signal. Rotary encoder) 3, distance measurement value acquisition key 4, horizontal angle acquisition key 5, altitude angle acquisition key 6, coordinate value introduction key 7, and the corresponding distance measurement signal by turning on keys 4, 5, and 6.7, A microcomputer 9 and a backup power supply 10 take in the horizontal angle signal, altitude angle signal, and coordinate value signal and store them in the first storage device 8, so that even if the main power supply (not shown) is turned off, the memory of the computer 9 is easily erased. '1f, the second storage device 11 stores the coordinate value and horizontal angle of the target point, adds 180 degrees to the horizontal angle stored in the second storage device 11, and calculates the horizontal angle signal t of the horizontal angle measuring device 2. The computer controls the horizontal angle movement key 12 so that this value is reached, and the display 13 displays the stored content of the second storage device 11, y! l-Display command key 14 to display
and has.

Next, the operation of the above-mentioned surveying instrument will be explained with reference to the flowchart of FIG. 2 and the diagram for explaining the surveying procedure of FIG. 3.

First, set the surveying instrument at the reference point Pa, operate the zero reset key (not shown) so that the horizontal angle signal of the horizontal angle measuring device 2 becomes zero with the magnetic north N as a reference, and also set the altitude angle with the zenith as a reference. Operate the zero reset key (not shown) so that the altitude angle signal of the measuring device 3 becomes zero (note that the altitude angle measuring device 3 automatically resets to zero when the standard telescope (not shown) comes to a position with the zenith as standard. A rotary encoder that generates a so-called origin signal is usually used).

Next, by pressing the coordinate value introduction key 7, the coordinate value (
Xo +Yo, Zo) is introduced into the computer 9,
Coordinate values (Xo, Yo, Zo) are stored in the first storage device 8.
'I memorize (step 20), then the target point P11
1t standard. During this time, the microcomputer 9 sets n=0Y in step 21. When the distance measurement value capture key 4 is operated with the target point P1 as a reference, the distance measurement signal from the distance measuring device 1 is captured into the computer 9, and the distance So from the reference point PG to the target point P1 is stored in the first memory. It is stored in the device 8, and when the horizontal angle capture key 5 is operated, the horizontal angle signal of the target point P1 is captured into the computer 9, and the horizontal angle α0 becomes the first
It is stored in the storage device 9, and when the altitude angle capture key 6 is operated, the altitude angle signal of the target point P1 is captured into the computer 9, and the altitude angle β0 is stored in the first memory device 8.

The computer 9 calculates the coordinate values (Xo + YOeZo) of the reference point Po stored in the first storage device 8, the distance 80% and the horizontal angle α0. The coordinate value of the target point P1 from the altitude angle β0 (XI IYI 1z1) is calculated as follows.

z1=S6ecosβo+Z.

Then, the computer 9 calculates the calculated coordinate value Ps of the target point PI = (XIIYIIZI) (!: horizontal angle α0
is stored in the second storage device 11 (step 22).

If you want to end the survey at this point, you can turn on the end switch (not shown) (step 23), but if you want to further measure the coordinate values of other points, move the surveying instrument to the target point Pi. After setting this point as a new measurement point, use the previous measurement point as the standard. Then, when the horizontal angle movement key 12 is operated (step 24), the horizontal angle α0 stored in the second storage device 11 is read out, and the horizontal angle measuring device 2 (step 25). Here, the computer adds 1 to n set in step 21, sets n=1, and returns to step 22 (step 26) 6. The operator rotates the reference telescope to the left and sets it to a new target point P2. , step 2
2, the new measurement point Pl stored in the second storage device
Coordinates P2 of target point Pz = (X21Y21Z2) fi are calculated based on coordinates (Xi + Y11z1), horizontal angle α1 measured by new 7tJC, altitude angle β1, and distance S1, and coordinates P2 of target point P2 and horizontal angle α! is stored in the second storage device 11 (step 22).

The same applies below.

In the above embodiment, since the second storage device 11 is backed up by the backup power supply 10, even if the main power is turned off to move the measurement point, the coordinate value Pn of the target point necessary for surveying and the horizontal Angle α. Since the information remains in memory, the inconvenience of transporting the surveying instrument with the main power turned on can be eliminated.

Furthermore, since the survey data (such as the coordinate value Pn of the target point) can be displayed on the display 13 by using the display command key 14, it is possible to check each survey at the site, which has a great effect.

The above explanation has been made on the clockwise basis, but in the case of the counterclockwise basis, the calculation (αθ+180) in step 25 becomes the calculation (αo 180). Of course, α0 in this case is also the horizontal angle of the target point measured counterclockwise. If it is possible to select between the clockwise reference and the counterclockwise reference in one device, a selection switch may be provided so that the computer can switch calculations based on a signal from the switch.

(Effects of the Invention) As described above, according to the present invention, when the surveying instrument is moved to the Yamaguchi gauge point and set as a new measurement point, and the old measurement point is defined as a new target point, the operation is performed. An actuating means for outputting an actuating signal is provided, and when the actuating signal from the actuating means is input, the horizontal angle signal of the horizontal angle measuring device is changed to the output of the horizontal angle measuring device based on the horizontal angle stored in the storage device. Since a preset device is provided to set the horizontal angle signal as the angle value of a new target point at a new measurement point, there is no need to refer to the magnetic north when moving from one measurement point to another, and the magnetic north always refers to the reference point. can be used as the measurement reference, so correction calculations etc. are not required, and furthermore, the angle value of the old measurement point at the new measurement point is automatically preset to the horizontal angle signal output by the horizontal angle measurement device by actuation of the actuation means. Therefore, a surveying instrument with good operability can be obtained.
