Apparatus, method and system for antenna alignment

Abstract

The invention relates to the field of communication and transmission, and particularly discloses a device, a method and a system for antenna alignment. The method comprises the following steps: receiving an input signal and outputting a received signal strength indicator (RSSI) according to the input signal; receiving the RSSI and acquiring the actual received power value relative to the input signal by searching the RSSI and the power correspondence table; and comparing the actual received power value relative with the theoretic received power threshold value, and when the actual received power value is less than the theoretic received power threshold value, outputting an antenna rotation signal; when the actual received power value is more than or equal to the theoretic received power threshold value, outputting an alignment indication signal; adjusting an antenna to change the receiving angle of the antenna according to the antenna rotation signal; and aligning the antenna according to the alignment indication signal. The method reduces the artificial operation error and effectively ensures the network quality.

Description

technical field [0001] The present invention relates to the field of communication transmission, in particular to an antenna alignment device, method and system. Background technique [0002] In a microwave system, the structure schematic diagram of the antenna alignment device in the prior art is shown as figure 1 As shown in the figure, it is divided into indoor unit, outdoor unit and antenna. The indoor unit and outdoor unit are installed separately and connected by an intermediate frequency cable. For normal communication between two microwave sites, the antennas must be aligned, so as to ensure normal transmission and reception of signals between microwave sites. For antenna alignment, the prior art method is to design a received power level indication interface on the outdoor unit, and the interface outputs a voltage signal proportional to the received power. Such as figure 1 Shown: The outdoor unit of the microwave system outputs RSSI (Receiver Signal Strength Indi...

AI Technical Summary

Problems solved by technology

[0003] During the research process, the inventor found that the antenna adjustment method in the prior art is cumbersome, and the voltage signal needs to be tested while adjusting the antenna. Usually, two people are required to cooperate to complete it. One person is responsible for keying the instrument and checking data, and the other is responsible for Adjusting the antenna requires a lot of manpower

If it is done by one person, it is necessary to repeatedly test the data and adjust the antenna repeatedly, and the debugging efficiency is lower, which requires relatively high labor costs
