る。[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a point setting device that allows the target side to know the line of sight direction of a surveying instrument.

準線方向を知るためのポイント設定用コリメータ
装置が提案されている。(Background of the idea) Conventionally, there has been work to set points for piling using a surveying machine. In that case, the direction of the point is sighted using a surveying instrument capable of distance measurement and angle measurement, and the point is set by moving the target for distance measurement back and forth in the direction of the line of sight. At this time, it is a time-consuming and complicated task for the target side to receive movement direction instructions from the operator of the surveying instrument using a transceiver or the like and to align the target with the line of sight. Therefore, a point setting collimator device has been proposed for determining the line of sight direction of a surveying instrument on the target side.

平行でかつ又同一鉛直面内にあるように測量機に
取り付ける。 This device consists of diffusing plates of different colors, for example, green and red, placed on the left and right sides of the focal plane of the collimator lens across the optical axis, and a light source is installed behind them.This collimator device is used for surveying. Attach it to the surveying instrument so that the instrument and the optical axis are parallel and in the same vertical plane.

分が測量機の視準線付近にいることがわかるので
ある。 Then, when you look at the surveying instrument near the target, the light from the collimator device enters your eyes, and you can tell by its color whether you should move to the left or right. In other words, you know in advance what color will be on either side of the sight line of the surveying instrument, so for example, if you are currently looking at green, you should know that if you move to the right, you should see red. For example, if you move to the right side while holding the target and stand at the exact border point where you can see the green and red colors, you will know that you are almost in the line of sight of the surveying instrument.
ところが従来のコリメータ装置では、上述の如

る、という欠点があつた。 However, with conventional collimator devices, as mentioned above, the person setting the target side has to adjust the position while looking at the color of the light, which makes it difficult to see in a bright place or at a large distance, making it difficult to set the position.

The light emitting device 1 holding the objective lens 5 is attached to the surveying instrument 100 so that the angles 2 and 2 substantially coincide with each other. A right-angle prism 4 having a ridgeline on the optical axis of an objective lens 5 and in the vertical direction (perpendicular to the plane of the paper) is disposed within the light-emitting device 1, and a light source 2 is provided on one reflective surface side of the right-angle prism 4. However, a light source 3 is provided on the other reflective surface side. The light sources 2 and 3 blink at different frequencies, as will be described later. Note that the light sources 2 and 3 are arranged approximately on the optical axis of an objective lens 5 bent at a right angle by the ridge line of the right-angle prism 4, as shown in the figure.

る。 A target (not shown) installed at a predetermined point includes a light receiving element 7 that receives the emitted light from the light sources 2 and 3 and converts it into an electrical signal, and a light receiving element 7 that performs frequency discrimination on the output signal of the light receiving element 7. A display device 6 having an arithmetic display circuit 8 for displaying which light source is receiving light emitted from the light source is attached.

In case of trouble, display 13,
14 are both turned on.

る。 The drive device for the light sources 2 and 3 is constructed as shown in FIG. 3, and modulates the light source 3 via a drive circuit 31 with a signal of a predetermined frequency f 1 from an oscillator 30, thereby controlling the light source 3 at a frequency f 1 . The signal of frequency f 1 from the oscillator 30 is converted to frequency f 2 by the frequency dividing circuit 32, and then the light source 2 is modulated through the drive circuit 33, thereby causing the light source 2 to blink at the frequency f 2 . .

ら、発光器１３，１４が共に点滅する。 Further, the calculation display circuit is constructed as shown in FIG. That is, the photoelectric conversion signal from the light-receiving element 7 is amplified by the amplifier 60, and then passed through the first bandpass filter 61, which passes only the frequency f2 .
The signal is input to the second band pass filter 62 through which only the signal is passed. The first bandpass filter 61 has a frequency f 2
Therefore, if the output signal of the amplifier 60 has a frequency f 2 , the light emitter 13 blinks at the frequency f 2 via the drive circuit 63. Similarly, when a signal with the frequency f 1 is output from the amplifier 60, the light emitter 14 blinks at the frequency f 1 via the drive circuit 64. Further, the light receiving element 7 is connected to the optical axis 12 of the objective lens 5.
When substantially within a vertical plane containing the amplifier 60
Since the signals of frequency f 1 and frequency f 2 are outputted from , the light emitters 13 and 14 both blink.

受光し、発光素子１３が周波数f2で点滅する。 With such a configuration, for example, the display device 6
When the light beam deviates from the optical axis 12 and moves to the region 9 as shown by 6', the light receiving element 7 receives the light beam blinking at the frequency f1 , and the light emitting element 14 blinks at the frequency f1 . Further, when the display device 6 is moved to the area 10, the light receiving element 7 receives the light beam blinking at the frequency f2 , and the light emitting element 13 blinks at the frequency f2 .
従つて、受光素子７を光軸１２に一致させるた
めには、点滅している発光素子１３又は１４の矢
印の方向に表示装置６を移動し、発光素子１３と
１４とが共に点滅するようになせばよい。 Therefore, in order to align the light receiving element 7 with the optical axis 12, move the display device 6 in the direction of the arrow of the blinking light emitting element 13 or 14 so that both the light emitting elements 13 and 14 blink. Just do it.

なお、以上の説明は、水平方向での位置合わせ
を行なう例であるが、発光装置１を光軸１２のま
わりに90度回転できる構造とすれば、鉛直方向で
の位置合せを行なうこともできる。 Although the above explanation is an example of alignment in the horizontal direction, alignment in the vertical direction is also possible if the light emitting device 1 is structured to be able to rotate 90 degrees around the optical axis 12. .

とができる。 Furthermore, a device is configured that automatically aligns the target with a vertical plane passing through the optical axis 12 based on the signal output from the light receiving element, and the device is mounted on a device that can be freely moved using a communication means. Once placed, the operator on the survey instrument side can use communication to move the moving device approximately to the vicinity of the desired point and automatically place the target on the optical axis 12 with high precision.

遠隔操作により設定可能となる。 That is, if a data transmission device is used, which includes a modulation device that modulates the light source of the light emitting device 1 in accordance with transmitted data, and a light receiving device that receives and demodulates the modulated light emitted from the light source on the target side, light emission is possible. Since the point to be set on the optical axis is defined by the signal from the device 1, the target automatically stands on the set point, and the point can be set on the floor, ground, etc. by remote control.
