Abstract

PURPOSE:To facilitate the positive facing of a reflecting member with a surveying machine without troublesome labor, by driving reflecting members set at a plurality of known coordinate points through a remote operation. CONSTITUTION:A control member 100 issues commands for depression/elevation- wise and horizontal rotations. A transmitter 1 receives a command from the member 100 to emit radio waves of varied frequency. A receiver 2 receives this radio wave to identify a horizontal rotation command signal and a depression/elevation-wise rotation command signal to be inputted into a corresponding horizontal drive section 3 and depression/elevation-wise rotation drive section 4. The drive section 3 (4) is connected to a motor 6 (5) for horizontal (depression/elevation-wise) rotation, which 6 (5) is fixed to a pedestal (support member 13) to rotate the member 13 with respect to the pedestal horizontally (the reflecting member 12 rotates in depression and elevation). The receiver 2, the drive section 3 and the like are placed a two known coordinate points together with the member 12 and when the member 100 is operated, the member 12 rotates horizontally and in depression and elevation to optimize the direction thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a direction adjustment device for a reflecting member for light wave ranging used in surveying work.

(Background of the Invention) Conventionally, all distance and angle measurements have been carried out using a light wave i111 distance reflecting member installed at two known coordinate points, installed at all measurement points of survey +fA having distance measurement and angle measurement functions. Surveying is carried out using the so-called backward intersection method, in which the coordinates of a measurement point are determined by calculation.

There are few places to conduct such surveys using the back intersection method, and it is necessary to directly face the surveying machine with all reflective members installed at known coordinate points, but since the measurement point moves, the orientation of the reflective member must be fully adjusted. It won't happen. Therefore, conventionally, the orientation of the reflecting mirror has to be changed manually as the measurement point moves, that is, the position of the measuring device is moved, which has the disadvantage of being time-consuming.

(Object of the Invention) The present invention relates to a direction adjustment device for a reflecting member for distance measurement, which solves the above-mentioned drawbacks and completely reduces the labor and effort of surveying work.

(Summary of the Invention) The present invention includes at least one reflecting member 12 and a holding device 1 that holds the reflecting member 12 such that the reflecting member 12 can be freely rotated in the entire elevation and horizontal direction.
3, in a direction adjustment device for a distance measuring reflective member used with a σ1 surveying instrument, there is an operating member 100 placed on the surveying instrument side to issue an elevation rotation command and a horizontal rotation command.
Based on this operation member 1000 command, a transmission device 1.2.3.4 for transmitting and outputting an elevation rotation command signal and a horizontal rotation command signal to the reflective member side is provided, and the holding device 13 is , a first electric drive device 5 that rotates the reflecting member 12 in its entire elevation and elevation by the human input of the elevation rotation command signal; and a second electric drive device 5 that rotates the reflection member 12 horizontally in response to the horizontal rotation instruction signal; This is a direction adjusting device for a reflecting member for distance measurement, which is characterized by being provided with a drive device 6, and since the direction of the reflecting member is adjusted by remote control, it is possible to reduce the labor involved in surveying work.

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

FIG. 1 is a block diagram of one embodiment of the present invention. The operating member 100 is used to issue an elevation rotation command and a horizontal rotation command, and the operator can input the commands using a joystick, buttons, or the like. The transmitter 1 determines which command from the operating member 100 is transmitted manually, and emits, for example, radio waves of different frequencies.

The receiver 2 receives all the radio waves emitted from the transmitter 1, distinguishes the horizontal rotation command signal and the elevation rotation command signal, and inputs them into the corresponding sales I drive range 3.4. The horizontal rotation circuit 3 is connected to the horizontal rotation motor 6, and the elevation rotation and drive circuit 4 is connected to the elevation rotation motor 5.

The horizontal rotation motor 6 is fixed to a base (not shown) and is used to horizontally rotate the support member 13 with respect to the base.

The vertical rotation motor 5 is fixed to the support member 13 and is used to rotate the reflecting member 12 vertically.

The solar cell 7 receives sunlight and generates a current, and this current is stored in a storage battery 8.

The storage battery 8 is input to the power supply circuit 9 via a switch 81.
1 power supply circuit 9 serves as a power source for the receiver 2, and also serves as a power source for the 17'c drive circuit 3.4 and the motor 5.6. A light receiving element 10 such as a CDS monitors outdoor brightness, and a control circuit 11 turns off the switch S+t'' when the signal level from the light receiving element 10 becomes less than a predetermined value.

With such a configuration, together with the reflecting member 12, the receiver 2, the driving member 3.4, the solar cell 7, the storage battery 8, the power supply circuit 9, the light receiving element 10, the control circuit 11, the switch S, (i
- If placed in two known coordinate boilers, 4111 on the surveying machine side
The operator can rotate the reflecting member 12 horizontally and vertically by simply operating the operating member 100, thereby optimizing the direction of the reflecting member 12.

According to the above embodiment, not only can the direction of the reflective member located far from the surveying instrument be adjusted by remote control, but also the direction of the reflective member located far away from the surveying instrument can be adjusted by remote control. I (reflective member side) has a combination of solar cells 7 and storage batteries 8 all around it as a power source, so it can be used even in places where there is no power source, and because of the storage batteries 8, it can be used without problems even in rainy weather. can.

Furthermore, the light receiving element 101 control circuit 11, the switch S+k
Since the switch SI is used, when the surroundings are dark, that is, at night, the switch SI is turned off and power can be saved.

In the above embodiment, the transmitter 1 and the receiver 2 on the side of the reflective member 12 located at a remote location from the transmitter 1 are coupled wirelessly using open sound radio waves, but it is also possible to couple the transmitter 1 by optical communication or by wire. Of course, signal transmission may also be carried out by

Further, the operation member 100 may also be used as an operation panel of a surveying instrument, and may be used for full light wave communication for distance measurement. In this case, since the orientation is not constant on the reflective member 12 side, it would be a problem if the receiver is located in a position where the light waves cannot enter, so multiple receivers are provided and any one of the receivers is set regardless of the orientation of the reflective member. It must be arranged so that light waves can enter.

FIG. 2 shows a specific example of the arrangement of the reflecting members 12, and when a plurality of reflecting members 12 are used, by arranging them horizontally, compared to polygonal or vertical arrangement, the supporting parts of the reflecting members 12 can be arranged more easily. 13 can be lowered, and stability against wind and the like can be achieved. Further, in a case where the number of reflecting members 12 is changed (for example, a case in which only the central reflecting member 12 is used for short-range distance measurement), there is an advantage that the height of the side elevation does not change.

Note that a display member 14 is fixed to the support of the reflective member 12, and the member 14 has its a side, a' side, b side, and b' side painted in different colors, respectively. For example, if the reflective member 12 is shifted to the left or right with respect to the surveying instrument, only one color of the a-plane or the a'-plane can be seen. Similarly, if it is shifted vertically, only plane b or b' can be seen. In other words, the color boundary between the a side and the a' side, and the color boundary between the b side and b' side are when the reflective member 12 is directly facing the surveying instrument. In this way, the member 14 (total reflection part)
There are four side plates that can be added to the support part 13 to easily determine whether or not they are facing each other by color identification.
It can be a different color, for example, A-side, B-side golden yellow.
However, the a/b' side may be made black.

As described above, according to the present invention, by driving the reflective members installed at a plurality of known coordinate points by remote control, it is possible to easily make them directly face a surveying instrument without bothering human hands. I can do it.
