However, both alignment detection approaches have limitations. The former uses a manual mode to collect and observe the state of the equipment, and the alignment difficulty is higher, the precision is lower and the time consumption is longer; the latter, though having a high degree of automation, is complex in mechanism, not portable, limited in application scenarios and high in cost.
In particular, the invention patent application with the patent application number of 200810188022.X discloses an antenna alignment method, system and device. The method comprises the following steps: acquiring coarse tuning information of antenna alignment according to a scanning result between a first scanning antenna on a local communication antenna and a second scanning antenna on a target communication antenna; according to the coarse tuning information, coarse tuning is carried out on the local communication antenna and the target communication antenna through the control device on the ground; and according to the indication of the alignment indicating device, finely adjusting the local communication antenna and the target communication antenna after the coarse adjustment through an operating device on the ground so as to align the local communication antenna and the target communication antenna. In the embodiment of the invention, the control on the direction of the antenna at the tower top can be realized on the ground through the ground control device and the alignment indicating device, so that the antenna alignment is completed, the time of high-altitude operation of an installer is reduced, the danger of the antenna alignment operation is reduced, the antenna alignment efficiency can be effectively improved, and the time and the labor are saved.

The invention has the advantages that the whole alignment process can be completed fully automatically without human interference, and the alignment precision is high. The technical scheme adopted by the method is free of a gyroscope, a compass and the like are used for angle sensing, and the accuracy of system signal alignment angle is slightly poor due to large angle errors measured by geographical and surrounding magnetic field environment changes; in addition, the method needs to use a holder, and is large in size and not easy to install.

In this manner, when the laser receiver mounted on the first microwave antenna 120 receives the laser light emitted from the laser emitting device 130 mounted on the first microwave antenna 120 and emitted via the reflecting prism 140 mounted on the second microwave antenna, it indicates that the first microwave antenna 120 and the second microwave antenna are in an aligned state in the current rotational direction, and at this time, the rotation of the adjustment mechanism 110 is stopped, and the first microwave antenna 120 can be fixed at the aligned position with respect to the second microwave antenna.
Fig. 2 illustrates an alignment apparatus 200 for microwave antennas according to a second embodiment of the present invention, and as can be seen from the figure, the alignment apparatus 200 for microwave antennas includes an adjustment mechanism 110, the adjustment mechanism 110 is configured to be capable of rotating a first microwave antenna 120 coupled to the adjustment mechanism to adjust an angle of the first microwave antenna 120 coupled to the adjustment mechanism in a first direction and/or a second direction; in addition, the alignment apparatus 200 for microwave antenna further includes a laser emitting device 130, the laser emitting device 130 being configured to be mounted on the first microwave antenna 120 and to emit laser light. Furthermore, the alignment apparatus 200 for microwave antenna further comprises a microwave antenna alignment determination apparatus, which is at least partially installed on a second microwave antenna (not shown in the figure) and configured to determine the alignment status of the first microwave antenna 120 and the second microwave antenna according to the laser emitted by the laser emitting apparatus 130, wherein the direction of the laser received by the portion of the microwave antenna alignment determination apparatus coupled with the second microwave antenna corresponds to the direction of the microwave signal received by the second microwave antenna from the first microwave antenna 120. In the aligning apparatus 200 for a microwave antenna according to the second embodiment of the present invention shown in fig. 2, the microwave antenna alignment determining apparatus includes a laser receiver (not shown in the drawings) which is disposed on the second microwave antenna and whose laser receiving direction corresponds to the receiving direction of the second microwave antenna. In this way, when the laser receiver mounted on the second microwave antenna receives the laser light emitted from the laser emitting device 130 mounted on the first microwave antenna 120, it indicates that the first microwave antenna 120 and the second microwave antenna are in an aligned state in the current rotation direction, and at this time, the rotation of the adjustment mechanism 110 is stopped, and the first microwave antenna 120 can be fixed at the aligned position with respect to the second microwave antenna.

In this embodiment, if the pitch angle of the first microwave antenna 120 needs to be adjusted, i.e., the angle of the first microwave antenna 120 is adjusted in the second direction, then the laser transmitter of the laser transmitter needs to be rotated by 90 degrees, such that when the adjustment mechanism 110 of figure 1 swings the first microwave antenna 120 in the second direction, the laser emission can generate a laser plane perpendicular to the second direction, i.e., the first direction, and when the laser receiver mounted on the first microwave antenna 120 receives the laser light emitted from the laser emitting device 130 mounted on the first microwave antenna 120 and emitted via the reflecting prism 140 mounted on the second microwave antenna, indicating that the first microwave antenna 120 and the second microwave antenna are aligned in the current rotational direction, at which time the rotation of the adjustment mechanism 110 in the second direction is stopped, the first microwave antenna 120 can be fixed in an aligned position relative to the second microwave antenna.
