Abstract

PURPOSE: To easily make an operator looking at through a telescope of a total station give a signal to an operator on the reflection target side so as to facilitate a piling work by providing a voice generation means on a light wave range finder, and generating a voice when a measured distance is conformed to a programmed data. CONSTITUTION: Previously input data is read from a memory 40, and angle measuring of a horizontal plane is executed by an angle measuring part 20. When the measured angle value is in a prescribed range, a CPU 30 oscillates an oscillator 70 so as to output a buzzer sound through a piezoelectric buzzer sounding body 80. When it is not in the prescribed range, a light wave range finder is horizontally finely rotationally moved until buzzing. Further by consituting it so as to generate a voice, the work is made easier. Next, a distance is measured, and measured distance data is compared with data previously input by the CPU 30. When the measured distance data is smaller than a prescribed value, to the f1 side of the oscillator, and when larger, to the f2 side, a switch 60 is made ON so as to buzz, and this operation is repeated until it is conformed to the prescribed value.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical distance meter which displays a measured value on a display unit and generates a sound when the measured value matches the program data.

[0002]

2. Description of the Related Art Generally, stakeout work is performed by inputting a designed distance value as program data in three-dimensional coordinates (distance, horizontal angle, altitude angle) to a total station (ranging and measuring device). Every time, an operator with a reflection target moves so as to face the total station with the telescope facing the predetermined point and the distance measuring direction, and sets the reflection prism to the distance measurement value, thereby designing the pile. Distance values are sequentially specified by a reflecting prism, and a peg is struck at the specified position.

That is, as shown in FIG. 4, the total station includes measurement data measured by the angle measuring unit 110 and distance measuring unit 120 and data (program data) stored in advance in the memory (internal or external) 130. To the calculation unit (C
(PU) 140, and the difference between the measurement data and the program data is displayed on the display unit 150.

Therefore, the operator sends a signal to the operator having the target so that this numerical value becomes 0 while observing the numerical display on the display unit 150 of the total station.

FIG. 5 is a flow chart showing a measuring procedure for stakeout work by a total station. Stakeout data is read from the memory 130 in step S1, and horizontal angle is measured by the angle measuring unit 110 in step S2. , This angle measurement data is transferred to the CPU 140. The CPU 140 compares the data stored in the memory 130 in advance and displays the angle difference.

Here, the display unit 15 is arranged so that the angle difference becomes zero.
Check with 0. Next, in step S3, the distance measuring unit 1
Distance measurement is performed by 20. In step S3, the distance measurement data is compared with the data stored in advance in the memory 130, and the distance difference is displayed. Here, the display unit 150 confirms that the distance difference becomes zero. Then, the stakeout location is specified, the stakeout operation is performed, the next stakeout operation is sequentially performed, and the work is continued until the final stakeout operation is completed.

As described above, when the distance is measured, the distance measurement data is displayed, and the measurement result is displayed on the display unit in a state of being compared with the preset data. The operator could not recognize the position of the reflective target unless he moved his eyes from the telescope to the display.

As described above, in order to eliminate the inconvenience of constantly gazing at the display section, when the calculation section 140 outputs the measurement result to the display section 150, a technique of outputting an urging signal to the signal sound generating device for a short time. Is known (Japanese Patent Laid-Open No. 54-913).
(See No. 64, page 7, column 1, lines 13 to 16).

However, also in this case, only a signal sound is generated when the measurement result is displayed, and the operator cannot recognize the position of the reflection target unless the eyes are moved from the telescope to the display section. That inconvenience remained.

[0010]

As described above, in the stakeout work, an operator looking through the telescope of the total station always looks at the display unit and then gives a signal to the operator on the target side. I have to
For workers looking into the telescope of the total station, there was the inconvenience that they could not work quickly because they were very troublesome.

It is an object of the present invention to provide an optical distance meter that facilitates a pile driving operation by facilitating an operator looking through a telescope of a total station to signal an operator on the reflection target side.

[0012]

According to a first aspect of the present invention, there is provided a lightwave distance meter for performing distance measurement according to a preprogrammed process and displaying the distance measurement data on a display unit. Is provided with a voice generation means, and generates a voice when the measured distance value substantially matches the programmed data.

Further, it is preferable that the voice is configured so as to be different depending on whether the distance is smaller than the programmed data or larger than the programmed data.

Further, according to a third aspect of the present invention, the lightwave distance meter is a distance measuring and angle measuring device for performing distance measuring and angle measuring according to a preprogrammed process and displaying the distance measuring and angle measuring data on the display unit. The voice is preferably configured to be either loud or soft in proportion to the distance measurement value or the angle measurement value moving away from the preprogrammed data value.

According to a fourth aspect of the present invention, the lightwave rangefinder is a rangefinder and rangefinder that performs rangefinding and angle measurement according to a preprogrammed process and displays the rangefinding and angle measurement data on the display unit. It is preferable to generate a sound when the measured angle value matches the programmed data.

[0016]

[Operation] When the measured value agrees with the preset program data, the sound generating means generates a sound, which allows the operator on the side of the optical rangefinder to stake out the reflection target while looking through the collimation telescope. It is possible to detect that the distance value has become the upper value and signal the operator of the reflection target side without looking at the display unit.

Therefore, the operator on the total station side can easily give a signal to the operator on the reflection target side, and the pile driving work can be carried out quickly and easily. In addition, it can be judged by voice whether the reflection target is closer or farther than the distance value in the piling design.

Then, when the total station is horizontally rotated and the angle measurement data matches the programmed angle measurement data, a sound is generated, which makes it possible to know the direction in which the total station is roughly oriented without looking at the display section, and then fine movement horizontal. The target may be collimated by rotating it.

An embodiment of the present invention will be described below with reference to the drawings. The members, arrangements, and the like described below do not limit the present invention and can be variously modified within the scope of the gist of the present invention.

FIG. 1 is a block diagram of a lightwave rangefinder.
3 is a flowchart showing a processing procedure of the device of the present invention.

The optical distance meter in this example has the same basic structure as that of the prior art, except that the buzzer is operated by the oscillator when the measured data reaches a predetermined value. That is, as shown in FIG.
Angle measuring unit 20, calculation unit (CPU unit) 30, memory 4
0, a display unit 50, a switch 60, an oscillator 70 forming a buzzer, a piezoelectric buzzer sounding body 80, and a volume control 90 are main components.

The distance measuring unit 10 and the angle measuring unit 20 are the CPU unit 30.
The angle-measuring data and distance-measuring data measured by the distance-measuring unit 10 and the angle-measuring unit 20 are sent to the CPU unit 30. Further, the CPU unit 30 is connected to the memory 40, and the previously input data stored in the memory 40 is compared with the angle measurement data and the distance measurement data measured by the distance measuring unit 10 and the angle measuring unit 20. Is configured to.
The memory 40 in this example includes both an internal memory and an external memory.

A display unit 50 such as a CRT or a liquid crystal is connected to the CPU unit 30. The display unit 50 has the distance measurement data and the distance measurement data measured by the distance measurement unit 10 and the angle measurement unit 20. Is directly displayed, and the comparison data with the previously input data is also displayed. Further, in the CPU section 30 of this example,
Two oscillators f70 (f1, f
2) is connected, and the oscillator 70 (f1, f2) is
Each is connected to a piezoelectric buzzer sounding body 80.

The oscillators 70 (f1, f2) of this example have different amplitudes, so that the sounds output from the voice generator 80 are heard as different sounds. The volume of these voices can be arbitrarily changed by the voice control 90 connected between the CPU section 30 and the piezoelectric buzzer sounding body 80.

Here, the horizontal angle of the stakeout data is H
₁ , the distance is D ₁ , the angle measurement value is h ₁ , and the distance measurement value is d ₁ , the angle measurement range is, for example, H ₁ = h ₁ or H ₁ −Δh
When ≦ h ₁ ≦ H ₁ + Δh (Δh is empirically determined), the vibration of the oscillator f1 is transmitted to the piezoelectric buzzer sounding body 80 and a buzzer sound is emitted.

Next, regarding the distance, D ₁ −Δd ≧ d ₁ and D
Two cases of ₁ + Δd <d ₁ (Δd is empirically determined) are calculated, and buzzer sounds with different pitches are notified by intermittent sounds.

Then, the distance measurement data measured by the distance measurement unit 10 and the data in the memory 40 are stored in the CPU unit 30.
In contrast, if the measured data value is smaller than the data value read from the memory 40, the switch 60
Is input to the oscillator f1 side, the vibration of the oscillator f1 is transmitted to the piezoelectric buzzer sounding body 80, and a buzzer sound is emitted.

When the data value measured in this way is smaller than the data value read from the memory 40, it means that the target is located closer to the lightwave rangefinder than the stakeout point.

When the measured distance data is larger than the data value read from the memory 40, the switch 60 is turned on to the oscillator f2 side, the vibration of the oscillator f2 is transmitted to the piezoelectric buzzer sounding body 80, and the buzzer sounds. in this way,
If the measured distance data is larger than the data value read from the memory 40, then the distance from the stakeout point,
Means the target is located.

Next, the stakeout work (stakeout work) by the lightwave distance meter according to the present invention will be described with reference to the flowchart shown in FIG. 2 as an example. The stakeout data is stored in advance in the memory card or the memory 40 of the lightwave distance meter, and the next data is read sequentially each time the stakeout operation is performed.

In FIG. 2, data input in advance is read from the memory 40 in step S1. In step S2, the angle measuring unit 20 measures the angle of the horizontal plane.
That is, the horizontal angle is measured by horizontally rotating the optical distance meter, and the measured angle value is displayed on the display unit 50. In step S3, the CPU section 30 determines whether or not the angle measurement value measured by the angle measurement section 20 is within a predetermined range. If it is within the predetermined range, the oscillator f1 is vibrated in step S4 to generate a piezoelectric buzzer sound. A buzzer sounds through the body 80.

If it is not within the predetermined range, the buzzer does not sound, and therefore the operator horizontally finely rotates the lightwave rangefinder until the buzzer sounds. It should be noted that if the sound is generated when the measured angle value matches the programmed data, the work becomes easier. When the buzzer sounds when the data match, the angle measurement display of the display unit 50, that is, the position where the difference between the measured value and the specified value becomes 0 can be known without visually recognizing the display unit 50.

Next, in step S5, distance measurement is performed. Then, in step S6, the CPU 30 compares the distance measurement data d ₁ with the previously input program data. When the distance measurement data is smaller than the specified value, the switch 60 is turned on to the oscillator f1 to make the buzzer sound at step S8. Then, the process loops to step S6. If the distance measurement data is larger than the specified value, the switch 60 is turned on to the oscillator f2 to make the buzzer sound at step S7. Then, the process loops to step S6.

The loop to step S6 is performed until the distance measurement value and the specified value become the same. In this example, the worker on the side of the optical rangefinder uses the buzzer sound (bass, treble) so that the position of the reflection target (side worker) is too close to the distance value on the pile driving design (too close to the side of the optical rangefinder). ) Is too far, and it is possible to send a signal for instructing the operator on the target side in which direction to move without looking at the numerical display D ₁ -d ₁ on the display unit as in the conventional case. .

Then, when the target is moved as instructed and the target is positioned at the distance value in the pile driving design (D ₁ −
It can be seen that the buzzer stopped blowing (when d ₁ = 0) and the target was located at the distance value in the pile driving design.

When the measured distance value and the designed distance value are the same, in step S9, stakeout is performed.
Do the work. After the stakeout work, step S
At 10, it is determined whether or not all the stakeout work is completed, and when all the stakeout work is completed, the work is completed at step S11. When all the stakeout work has not been completed, it returns to the measurement state.

It should be noted that the magnitude of the difference Δd at which the buzzer should be sounded (the difference between the stakeout scheduled point (known data) and the distance measurement data) can be arbitrarily set, and the user is not accustomed to the measurement method using this voice. For example, the length is set relatively large, for example, about 50 cm, and the time required for movements and cues of the operators on the target side and the optical distance meter side is shortened, while at the familiar stage, it is set as small as 20 cm for collimation. Therefore, it is possible to make adjustments such as reducing the time taken for ease and improving work efficiency.

FIG. 3 is a flow chart showing another processing procedure. In step S1, the previously input data is read from the memory 40. In step S2, the angle measuring unit 20 measures the angle of the horizontal plane. That is, the horizontal angle is measured by horizontally rotating the optical distance meter, and the measured angle value is displayed on the display unit 50. In step S3, the CPU section 30 determines whether or not the angle measurement value measured by the angle measurement section 20 is within a predetermined range, and if it is within the predetermined range, the angle difference is calculated in step S4. Then, in step 5, the volume control oscillator f is adjusted so that the volume becomes proportional to the angle difference.
1 is activated and a buzzer sounds.

If it is not within the predetermined range in step S3, the buzzer does not sound, and therefore the operator horizontally finely rotates the optical distance meter until the buzzer sounds. Then, in step S5, the buzzer sounds to recognize that the angle is within the predetermined range, and in this state, the angle measurement value is equal to the preset angle value until step S5.
A loop is formed between 4 and step S6.

When the angles match in step S6, the buzzer is stopped in step S7. Thereby, the angle measurement display of the display unit 50, that is, the position where the difference between the measured value and the specified value becomes 0 can be known without visually recognizing the display unit 50.

Next, in step S8, distance measurement is performed. The distance measurement data d ₁ measured in step S8 and the program data D ₁ input in advance are compared in step S9. If the distance measurement data d ₁ is smaller than the specified value D ₁ , the distance is calculated in step S10, and the switch is turned on to the oscillator f1 in step S11 to make the buzzer sound. At this time, the buzzer sounds with the volume control proportional to the distance. Then, the process loops to step S9.

If the distance measurement data d ₁ is larger than the specified value D ₁ , the distance is calculated in step S12, and step S13 is performed.
Then, the switch is turned on to the oscillator f2 to make the buzzer f2 sound. At this time, the buzzer sounds at a volume proportional to the distance. Then, the process loops to step S9. Each loop from step S9 to step S11 and from step S9 to step S13 is performed by the distance measurement value d ₁ and the specified value D ₁
Until they are the same.

Then, when the measured distance value d ₁ and the specified value D ₁ become the same in step S9, the buzzer is stopped in step S14. At this position, it is recognized that it is at the stakeout point, and stakeout work is performed in step S15.

Next, in step S16, it is determined whether or not all the stakeout work is completed. If all the stakeout work is completed, the work is completed in step S17, and all the stakeout work is completed. If not, the process loops to step S1.

As described above, the operator on the side of the lightwave rangefinder can know the stakeout point while collimating the telescope without looking at the data displayed on the display unit 50. It is easy to give a signal to a person, and quick work can be performed.

[0046]

According to the present invention, the optical distance meter is provided with the sound generating means and generates the sound when the distance measurement value substantially matches the programmed data. Since the position can be discriminated and the operator of the optical distance meter side can easily signal to the operator of the reflection target side, the pile driving work can be carried out quickly and easily. In this way, since the collimation work is conventionally performed while comparing the measured values, the pile driving work, which is performed while alternately viewing the telescope and the display, can be performed while looking through the telescope.

Further, according to the present invention, when the voice is configured to be different when the distance measurement is smaller than the programmed data and when the distance measurement is large, the distance of the reflection target in the piling design can be achieved without visually recognizing the display unit. It is possible to judge by the voice whether it is closer to the target than the value or far, and the position of the target can be judged by the kind of voice uttered like this,
Since it becomes easier for the operator of the light-wave rangefinder side to signal the operator of the reflection target side, the pile driving work can be carried out quickly and easily.

Further, according to a third aspect of the present invention, the lightwave rangefinder is a rangefinder and anglefinder that performs rangefinding and angle measurement according to a preprogrammed process and displays the rangefinding and angle measurement data on the display unit. If the voice is configured to be loud or soft in proportion to the distance measurement value or the angle measurement value deviating from the preprogrammed data value, the light wave distance can be set without looking at the display unit. You can see the direction to roughly aim the meter,
After that, the target is collimated by finely rotating horizontally, and the direction of separation from the stakeout point can be determined and the operator can be instructed to the reflective target side without visually recognizing the display unit during distance measurement.
