Description

[Detailed Description of the Invention] This invention relates to a detection mechanism for detecting the installation position and orientation of a large antenna or the like during installation work.

Conventionally, there was no dedicated mechanism for this type of mechanism, but each targeter was installed at the base of multiple antennas to be installed.It was measured and detected using a surveying instrument such as a theodolite or autocollimator installed at the center of the antenna. Was.

In this method, the installation accuracy of the installation device, such as the position accuracy,
In order to detect azimuth accuracy, it is necessary to perform calculation processing on survey data based on target position, azimuth, or target-to-target dimension conditions to detect the positional accuracy and azimuth accuracy.

The conventional method using a surveying instrument as described above has the drawback that it is not only difficult to obtain data by surveying, but also requires a large amount of time to process the data, resulting in poor efficiency.

This idea was devised to eliminate these drawbacks.The image of the target provided at the base of the antenna to be installed is focused using an optical system, and by comparing this image with a reference image, it is possible to directly see the target. The object of the present invention is to provide a detection mechanism that can detect the position and orientation based on the above.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of this invention. FIG. 2 is an explanatory diagram showing the principle of an embodiment of this invention. In FIG. 1, 1 is a base part provided radially with respect to the center of the installation position of an antenna (not shown), 2a 32b 52
3 is a triangular pyramid mirror, 4a, 4b, and 4c are objective lenses, 5 is a hairline, and 6 is an eyepiece.

12b and 12c are each of the above-mentioned Targera) 2a.

A triangular pyramid mirror 30 reflecting surface faces 2b and 2c via objective lenses 4a, 4b, and 4c; 13 is objective lens 4a

12c Target images of targets 11a, 11b, and 11c formed to have a rotationally symmetrical shape from K; 14 is a theoretical reference when targets 11a and 1ib tllc are arranged at the reference position and reference direction; The statue is located at hairline 5.

The hairline 5 is a transparent body, and the target image 13
is installed at the imaging position.

The target image 13 and the reference image 14 are arranged near the inner focal point of the eyepiece 6, and an enlarged target image 15 and an enlarged reference image 1 are formed.
It is configured to make 6.

In the above configuration, the target 11a provided on the inner surface of the positioning block 2a as shown in FIG. Target (11b, 1
A target image 13 is formed together with the image 1c (not shown in FIG. 2).

This target image 13 and the reference image 14 of the hairline 5 are simultaneously optically enlarged by the eyepiece 6 into the target image 1.
5 and an enlarged reference image 16 are formed.

The enlarged target image 15 and the enlarged reference image 16 formed in the above state are visually observed through the eyepiece lens 6.

Detects the installation position and orientation of the antenna.

Direction detection can be detected as a misalignment between the enlarged target image 15 and enlarged reference image 16, and one position detection can be detected as a misalignment between the enlarged target image 15 and enlarged reference image 16.

In addition, in the above embodiment, the target image 13 and the reference image 14
Although we have shown an example in which the image is optically magnified using the Kepler method and detected visually, it is of course possible to magnify and detect using the Galilean method, as well as using a magnifying glass method, an electronic display mechanism using pattern recognition, etc. Of course it is possible.

Further, in the above embodiment, the case of detecting the installation of an antenna device has been described, but it goes without saying that this invention can also be applied to a detection mechanism for detecting the installation position and installation direction when installing a jig or the like.

With this invention, even if the distance from the center to the target differs, it is easy to focus the target image on the same position by adjusting the objective lens.

As explained above, this invention has the effect that the installation position and installation direction of the antenna etc. can be easily detected by visual inspection or the like.
