Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention is a distance measuring method used for locating each point represented on a map at a site. The present invention relates to a surveying device having a function and an angle measurement function.

(Prior art) Conventionally, when performing side installation work to install each point on the site as each point represented on a map, before going to the site, the distance between each point is calculated from the coordinate values of each point on the map. Calculate the distance of each point and the angle of each point with respect to the reference direction, and write point data such as the distance between each point of the coordinate values of each point and the angle of each point with respect to the reference direction on the map, or After compiling the data into a table, they went to the site and installed the data at each point based on the data.

In addition, surveying instruments or surveying equipment used on site include:
Recently, devices have been used that perform distance and angle measurements by switching between a distance measurement mode and an angle measurement mode.

(Problems to be Solved by the Invention) By the way, in a surveying device used for surveying, which can perform distance measurement and angle measurement by appropriately switching between angle measurement mode and distance measurement mode, it is difficult to measure long distances. In order to receive the light from the light emitting part through the reflecting mirror placed at the point,
Considering the attenuation of reflected light, the amount of light emitted by the light emitting element must be made larger than the amount of light emitted by the light emitting device used in the angle measurement mode, and for this reason, the power consumption in the distance measurement mode is lower than that in the angle measurement mode. This is much larger than the power consumption.

Therefore, if the distance measurement mode is set unnecessarily during surveying work, the battery function will quickly deteriorate and the life of the '6R distance light emitting element will be shortened.

(Means for Solving the Problems) The present invention was made in view of the above-mentioned problems, and its feature is that light from a light emitting section is received through a reflecting mirror placed at a measuring point. , a distance measuring section that measures the distance to the measuring point, and an angle measuring section that measures the angle of the reference direction of the telescope.
a memory section that stores data for each point; a calculation section that calculates survey data necessary for surveying in a predetermined order based on the data stored in the memory section; the distance measurement section; and the angle measurement section. a display unit that displays a display according to the measurement results of the unit and the survey data obtained by the calculation unit;

Set the distance measurement mode when the above display section displays a display according to survey data related to distance, and set a mode other than distance measurement mode when the above display section does not display a display according to the survey data related to distance. It consists of a mode setting section that allows you to

(Function) According to the present invention, the calculation unit calculates the survey data in a predetermined order based on the data stored in the memory unit.
The display device displays information according to this survey data, but when the mode setting section displays information on the display device according to survey data related to distance, the distance measurement mode is set and the display device displays information according to survey data related to distance. A mode other than the ranging mode is set except when displaying.

(Example) An example of a surveying device according to the present invention will be described below with reference to the drawings.

The main body 1 includes a base plate 4 attached to a tripod 3, a telescope part 7 having a holder part 5 rotatable around a vertical axis with respect to the base plate 4, and a telescope 6 rotatable around a horizontal axis with respect to the holder part 5. It consists of

is located.

When the data collector 100 is not connected to the main body 1, the surveyor can use the first operation section 83 as shown in the configuration described below.
By operating the main body 1 alone, distance measurement or angle measurement to the reflecting mirror can be performed.

FIG. 3 shows a block diagram of a circuit built into the main body 1, and this circuit mainly consists of a distance measuring section 20, a horizontal distance measuring section 4, and a horizontal distance measuring section 4.

The first display 82 and the first operating section 83 are connected to the first control calculation section 80 .

The distance measuring section 20 receives light from a light emitting element 21, which is a light source, by a light receiving element 24 via a reflecting mirror 9 arranged at a measuring point, and determines the distance to the measuring point.

Light from the light emitting element 21 is selected by a chopper 22, and is emitted through a reflection prism 23 and an objective lens 6a. The light emitted from the objective lens 6a is reflected by the reflecting mirror 9, returns to the main body 1, passes through the objective lens 6a, is reflected by the reflecting prism 23, and is received by the light receiving element 24.

The light path described above constitutes an external ranging optical path.

On the other hand, in the distance measuring section 20, an internal reference optical path is formed from the light emitting element 21 to the light receiving element 24 via the reflecting mirror 25. The distance measuring section 20 has one oscillator 26, which generates a 15 MHz signal, and this signal is sent to the first switch 27.
1 frequency divider 28, combiner 30. and is supplied to the gate circuit 35.

Frequency divider 28 divides the 15 MHz signal from oscillator 26 to generate a 75 KHz signal and a 3 KHz signal.

The first switch 27 outputs a signal of either 15 MHz or 75 KHz to the light emitting element 21 via the amplifier 29 depending on the signal from the first control calculation section 80 . As a result, the light emitting element 21 emits modulated light of 15 MHz or 75 Hz.

The synthesizer 30 forms a 14°977 MHz signal, which is 3 KHz lower than the 15 MHz signal, and a 72 KHz signal, which is 3 KHz lower than the 75 Kl(z signal, and outputs them to the second switch 31.

When the first switch 27 is outputting a signal of 15 Hz to the light emitting element 21 in accordance with the signal from the first control calculation unit 80, the second switch 31 outputs a signal of 14.977 MHz to 75 MHz. 72K when outputting a Hz signal to
A Hz signal is output to the mixer 32. The signal from the light receiving element 24 is output to the mixer 32 via the amplifier 33.

The mixer 32 mixes the signal from the light receiving element 24 with the second switch 3.
By combining the signals from 1 to 3, a 3 kHz signal is output to the waveform shaper 34 regardless of whether the signal is from the first switching device or the second switching device.

The waveform shaper 34 converts the 3 KHz signal from the mixer 32 into a rectangular wave and outputs it to the gate circuit 35.

The gate circuit 35 uses the rise (or fall) of the 3 KHz signal from the frequency divider 28 as a start signal, and uses the rise (or fall) of the 3 KHz signal from the waveform shaper 28 as a stop signal. Oscillator 26 present within the period
A 15 MHz signal is output to the first counter 36.

This first counter 36 counts the signal from the gate circuit 35, and here, the 15M signal in the external distance measuring optical path is counted.
Two types of count values D related to Hz signal and 75KIIz signal
1. D, and two types of count values (Its (Is
The count value is reset by a signal from the first control calculation unit 80 so as to obtain the following.

The first control calculation unit 80 calculates the upper digit of the distance to the measurement point from the difference between the count value D1 and the count value d of the first counter, and calculates the distance to the measurement point from the difference between the count value D1 and the count value d. In coarse ranging mode, the lower digit of the distance is determined by averaging 64 times, and in precision ranging mode, the lower digit of the distance is determined by averaging 256 times.
It is displayed on the display 82. In addition, the first control calculation unit 80 selects coarse distance measurement mode, precision distance measurement mode, horizontal angle measurement mode, and altitude angle measurement mode using a signal from the first operation unit 83 or the second control calculation unit 101 of the data collector 100. select.

In the distance measuring section 20, the operation of each circuit section including the light emission of one light emitting element 21 is performed only when the distance measuring mode is selected by the first control calculation section 80, and when the distance measuring mode is not selected. (When the horizontal angle measurement mode or the like is selected), the light emitting element does not emit light or the like, contributing to power saving.

The horizontal angle measuring section 40 measures the rotation angle of the holder S with respect to the substrate 4 using an incremental encoder.

The rotating lattice plate 41 is composed of a disk-shaped glass plate in which a rotating lattice 41a having a transparent part and an opaque part at each predetermined angle (pitch) is provided circumferentially.

The first pulse generating circuit 48 generates pulses at the rising and falling timings of the output signals of the first Schmitt trigger circuit 46 and the second Schmitt trigger circuit 47, respectively, and outputs them to the second counter.

The first direction discrimination circuit 49 includes the first Schmitt trigger circuit 4
6. Based on the way the second Schmitt trigger circuit 47 comes out,
The rotation direction of the rotating grid plate 41 is discriminated, and the second counter 50

The second counter 50 counts the output pulses of the first pulse generation circuit 48 based on the output of the first direction discrimination circuit 49, and outputs the counted value to the first control calculation section 80.

This second counter 50 is configured so that its count value is reset by a zero set signal output from the first control calculation section 8o. Here, the zero set signal is generated when the telescope is aimed at the reference direction.
It is output based on the surveyor's operations.

The first control calculation unit 80 calculates the count “1” of the second counter 5o.
is converted into a 1/4 pitch rotation of the rotating grating, and this is displayed on the first display 82 as a horizontal angle.

The altitude angle measuring section 60 measures the rotation angle of the telescope section 7 with respect to the cradle section 5 using an incremental encoder.

Attach the other items to the rack section 5.
I am planning to install it on.

It is sufficient to know the relative amount of rotation, and there is no problem in mounting even if the objects are reversed.

The horizontal angle measuring section 40 and the altitude angle measuring section 60 described above operate as an angle measuring section, and the first calculation control section 80 operates as a mode setting section when the data collector 100 is connected. .

In this embodiment, the horizontal angle measuring section 40. Altitude angle measuring section 60
Since it is constituted by an incremental encoder, the measuring operation is continued no matter which mode the main body 1 is in. However, if the horizontal angle measuring section 40 and the altitude angle measuring section 60 are configured with absolute encoders or the like, they can be configured to operate only when the angle measurement mode is set, similar to the distance measuring section 20. Note that even when the data collector 100 is not connected to the main body 1, the distance to the survey point, horizontal angle, and altitude angle can be determined by the surveyor by selecting an appropriate mode using the first operation section 83. Measurement is performed, and the necessary data is stored in the first memory 81.

The second control calculation section 101 controls the main body 1 through the first control calculation section 80 according to a surveyor's command from the second operation section or a survey program stored in the program memory 103.
It performs various operations such as switching modes, displaying measurement results, etc., and calculating survey data necessary for surveying from various data stored in the second memory according to the survey program.

FIG. 5 shows a flowchart when the main body 1 and the data collector 100 are connected and a side program as one of the surveying programs is executed.

Here, the explanation of the flowchart will be explained later.
First, the side installation work will be briefly described with reference to the drawing in FIG.

Points A and B are known points that are already located on the site and are marked on a map or whose coordinates are given, and on the line connecting point A and point B. direction of
The side installation point (measurement point) indicated by the horizontal angles H1 and H7, which are defined as the reference direction, and the horizontal distance, HD, which is defined with point B as the reference, is defined as point C1.

Here, after installing the surveying device at point B, setting point A as a standard, and setting the horizontal angle to zero, standardize the horizontal angle 11□ direction, find the point at the distance of the horizontal distance HD, and set this on the side. Point C will be selected, and the side installation work will proceed in the same manner from now on.

When the side installation program is started, as shown in Figure 5,
Moving to step S, via the first control calculation section 80,
The mode of the main body 1 is switched to the horizontal angle measurement mode, and the process moves to step S. The horizontal angle setting mode consumes less power than the ranging mode, and this switching helps save power.

In STETUBUSHI, the surveyor inputs point names as point data of known points and side points and coordinate data as point data corresponding to the point names using the second operation unit 105. Enter the point names of this known point and side points, and the coordinate data corresponding to this point name.

This can also be done by sending data stored in an external storage device via an interface.

This input point data is stored in the second memory 102. When the input of this data is completed, the second operation section 1

On-site wintering is a name indicating the area where lateral installation work will be performed, and is used to extract coordinate data necessary for lateral installation in this on-site wintering area from among the input point data.

In step S4, the machine point number NO is input, and when the machine point number NO is inputted,

to move to.

The machine point number No. is the point where the surveying equipment is installed (hereinafter referred to as
This is the number NO of the machine point (called a machine point), and for convenience of input, it is designed so that the number can be typed in.

In step S, the back viewpoint number NO is input, and when the input of the back viewpoint number NO is completed, (EN

Back viewpoint number NO is a point used in combination with mechanical points to form a reference direction for surveying (hereinafter referred to as back viewpoint).
This is the number. In the example of FIG. 6, the rear viewpoint point for forming the reference direction for this survey is point A, and the one mechanical point is point B.

In step S6, the backsight of the backsight number No. inputted in step S is referenced with the telescope 6, and when the reference is completed, the process moves to step S7.

In step S7, the first operating section 83 or the second operating section 105 (

Proceed to step S. In this step S, the opening point number NO is input, and this opening point number N
When the input of o is completed, the process moves to step S9 by operating the (ENT) key.

This opening point number No. is the number of the opening point established at the site, and in the example of FIG. 6, it corresponds to point C1D.

In step Sg, the horizontal angle H and the horizontal distance 110 to the opening point based on the mechanical point and the reference direction formed by the mechanical point and the back point are calculated from the data stored in the second memory, and this calculation is performed. Upon completion, the process moves to step Sta.

In step S1°, the horizontal angle H determined in step Sg is displayed on the first display 82, and together with this display, the process moves to step S1□.

In step S1□, the surveyor rotates and sets the telescope unit 7 to the horizontal angle H displayed in step S8°.

When this horizontal angle setting is completed, the (ENT) key is operated and the process moves to step St+.

In this step St+, since the horizontal angle measurement mode has already been set in step S0, there is no need to change the mode here.

First, in step S1+, the mode of the main body 1 is switched to distance measurement mode via the first control calculation section 80, and in step S1
The horizontal distance HD obtained in , is sent as an offset value to the first control calculation unit 80, and the first control calculation unit 80
The distance to the reflector measured by main unit 1 is displayed in distance measurement mode.

In step SZa, the pole provided with one reflecting mirror 9 is moved in the direction in which the difference displayed on the first display 83 becomes rOJ, approximately aligned, and a survey stake is driven in. When this is completed, the (ENT) key is operated and the process moves to step S14.

This rough positioning is performed in a coarse measurement ratio mode in which the number of averaging is small, so that distance measurement time is short and rapid positioning work is possible.

In step S14, (ENT
> Precision ranging mode is set by key operation.

Then, the difference between the distance measurement result and the offset value is displayed in the same way as when the rough measurement ratio mode is set.

Here, the value is displayed in rrmtmJ, and the surveyor visually checks the displayed value in this precision distance measurement mode and performs operations such as driving a nail into the head of the pile that was driven in step SXS to locate the opening point. The fine positioning is completed with the mark 72 indicating . When this precise positioning is completed, the process moves to step S6. Step SL
In &, it is determined whether all the points (measurement points) to be opened for the machine points input in step S4 have been opened.

Here, if there are still points that have not been opened, the process moves to step S07. Then, the main body 1 is set to the horizontal angle setting mode, and the process returns to step S6 to input a new opening point number NO and continue opening.

In addition, if all the establishments for the input machine point have been completed, in step SXS that moves to step SXa,
It is determined whether the establishment of all machine points has been completed.

If there are any machine points that have not been opened, proceed to step S, set the main body 1 to horizontal angle measurement mode, return to step S4, and enter a new machine point number. , the opening is continued, and once the opening of all machine points is completed, the opening work is completed.

As described above, the second control calculation section 101 plays the role of a calculation section.

It should be noted that establishment is also performed for the altitude angle according to a similar flowchart.

(Effects of the Invention) As described above, according to the present invention, the distance measuring section, which consumes a large amount of power, obtains measurement data regarding distance in the calculation section and performs the measurement when displaying the corresponding data on the display section. When the distance mode is set and the display section displays data according to survey data other than distance-related survey data, the mode is set so that the parts other than the distance measuring tool, which consumes a large amount of power, are operated, resulting in a power saving effect.
