Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 Shown is a fully automatic alignment device for directional antennas, including a sensing module, a reliable communication module, an automatic alignment device, a directional antenna and an automatic control module; each part will be described in detail below.

[0030] The sensing module is used to obtain the azimuth information and height information of the directional antenna on the own side; specifically, it includes a GPS unit and an altimeter, and the obtained information includes latitude and longitude, altitude, antenna height and the like.

[0031] The reliable communication module is used for exchanging azimuth information, height information, transmit power, receive gain, fine-tuned actual maximum receive power and alignment state information of the own-side directional antenna and the opposite-side directional antenna; specifically, ...

Abstract

The invention discloses a full-automatic directional antenna alignment device and method. The method includes the steps of according to azimuth information and height information of a self-side directional antenna and an opposite-side directional antenna, inquiring for a topographic database, obtaining communication link topographic section information between the self-side directional antenna and the opposite-side directional antenna, and calculating communication link attenuation according to the communication link topographic section information; then calculating initial adjusting angles and initial pitch angles of the self-side directional antenna and the opposite-side directional antenna, and initially adjusting the self-side directional antenna and the opposite-side directional antenna; in cooperation with the communication link attenuation, setting initial transmitting power and initial receiving gains of the self-side directional antenna and the opposite-side directional antenna, and calculating the receiving power scope; respectively and finely adjusting the self-side directional antenna and the opposite-side directional antenna within the directional antenna finely-adjusting scope until the positions, with the maximum actual receiving power, of the self-side directional antenna and the opposite-side directional antenna are respectively found, and completing antenna alignment. By means of the full-automatic directional antenna alignment device and method, human interference is not needed, the whole alignment process can be completed in a full-automatic mode, and the alignment accuracy is high.

Description

technical field [0001] The invention relates to a fully automatic alignment device and method for a directional antenna, which belongs to the wireless communication technology. Background technique [0002] The existing directional antenna alignment methods are as follows: calculate the azimuth and elevation angle and then align according to the compass pointing, adjust the antenna angle and elevation angle according to the received power for alignment, and use the omnidirectional antenna to assist alignment. Several existing methods can be used alone or in combination to achieve manual or semi-automatic alignment of directional antennas, but currently there is no method for fully automatic alignment based on the position of the directional antenna to be aligned. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a fully automatic alignment device and method for directional ant...
