Of course, the alignment apparatus may implement another embodiment by simultaneously installing the same equipment on both the transmitting side and the receiving side as necessary.

Referring to the operation of the present invention configured as described above and the effects according to it in detail as follows.

The following M / W antenna alignment operation according to the present invention will be described taking the case of a microwave relay (M / W) antenna for inter-stations that are installed facing each other at two relay stations of several to several tens of kilometers.

First, in the transmitting relay station A and the receiving relay station B, a laser beam firing means 20 for emitting an infrared laser beam and a laser beam checking means 40 for measuring an infrared laser beam are respectively fixed means. The laser beam firing means 20 is directed to the receiving relay station B by fixing it perpendicularly to the rear surface thereof at the center position of the inter-station M / W antennas 10A and 10B using the 30A and 30B. Thus, the laser beam checking means 40 is directed toward the transmitting side relay station (A).

Then, when the laser beam firing means 20 is driven by the transmitting relay station A, the infrared laser beam emitted from the transmitting relay station A is transmitted to the station relay M / W antenna 10B of the receiving relay station B. ), And the receiving side relay station (B) can receive and measure the laser beam by the laser beam checking means (40).

By transmitting the reception and measurement results to the antenna equipment team of the transmitting relay station at the receiving side, the transmitting relay station (A) is based on the measurement result, and the M / W antenna for the station relay installed in the transmitting relay station ( The latitude and longitude of 10A) or up, down, left and right directions can be adjusted.

For example, if the M / W antenna 10A of the transmitting side relay station A is not in a correct position, the laser beam emitted from the transmitting side may be connected to the receiving relay station B as shown in FIG. It will not be aimed exactly at the laser beam identification means 40 but will be projected toward the up (a) or down (b) direction. On the other hand, if the M / W antenna 10A of the transmitting side relay station A is in the correct position, the laser beam emitted from the transmitting side checks the laser beam of the receiving relay station B as shown in FIG. The means 40 will be aimed to coincide with the laser beam projection direction of the central portion.

Therefore, when the laser beam is not projected on the laser beam checking means 40 at the receiving side, the result is notified to the transmitting side so that the transmitting side can adjust the M / W antenna in the up, down, left and right directions, or adjust latitude and longitude again. Thereafter, by repeatedly adjusting the laser beam until it is accurately aimed at the laser beam checking means 40, the transmitting side M / W antenna can be positioned.

In addition, when the laser beam is projected on the laser beam checking means 40, the transmitting side M / W antenna is fixed by fixing the M / W antenna position of the inter-station relay station of the transmitting side relay station along the laser beam projection position. It can be placed.

This sorting process may be performed by simultaneously installing the same sorting device on both the transmitting side and the receiving side as necessary. In this case, if the M / W antenna 10B of the receiving relay station B is not properly positioned, The laser beam emitted from the receiving side will be projected toward the upper (c) or lower (d) direction of the laser beam checking means of the transmitting relay station A, as shown in FIG. . On the other hand, if the M / W antenna 10B of the receiving relay station B is in the correct position, the laser beam emitted from the receiving side checks the laser beam of the transmitting relay station A as shown in FIG. It will be aimed at the means to coincide with the laser beam projection direction of the center part, in which case the antenna can be aligned much more effectively.

On the contrary, since the same applies to the case of adjusting the M / W antenna of the counterpart RS, the process is omitted.

Thereafter, by analyzing the M / W signal through the M / W reception acknowledgment means, the strength of the pilot signal is detected, and the result is converted into a predetermined unit, character or picture, and presented. It is possible to confirm whether the M / W signal transmitted from the M / W antenna 10A is normally received by the receiving side M / W antenna 10B.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

According to the present invention, since the laser having coherent and visibility can be directly identified by the eye, whether the directions of the transmitting and receiving antennas are well aimed at each other in a far position, vertical, horizontal, vertical, horizontal (latitude, longitude) ), And it is possible to improve the work efficiency by quick and easy positioning and alignment of two M / W antennas for inter-station relays ranging from several to several tens of kilometers. There is this.
