Description

Antenna attitude detection device

technical field

The utility model relates to the technical field of communication equipment detection, in particular to an antenna posture detection device.

Background technique

In wireless communication equipment, the base station antenna is used as the last link, directly transmitting electromagnetic waves to the mobile phone and receiving the electromagnetic wave signal emitted by the mobile phone at the same time. There are multiple vibrators inside the directional antenna of the mobile macro base station, which together form an electromagnetic beam and cover a certain area. Mobile phones in this area can communicate with the base station through the antenna.

The directional antenna of the macro base station is generally installed at a higher position such as the roof of a building or on a tower to ensure coverage. For the installation of the antenna, there are two important parameters, one is the horizontal azimuth angle of the antenna, and the other is the downtilt angle.

Please refer to FIG. 1 , which is a schematic structural diagram of a base station antenna arrangement in the prior art.

In Figure 1, α represents the physical downtilt angle when the antenna is installed. Its function keeps the coverage of the beam on the ground in a certain area (certain distance), and an important aspect is to avoid overlapping with the beam of the opposite base station. If the overlap is large, the mutual In addition, there is a phase shifter inside the general antenna, which can adjust the phase between the oscillators through the RCU to challenge the downtilt angle of the beam. This method is the electric downtilt angle, which works together with the physical downtilt angle α when the antenna is installed. Form the desired downtilt beam.

As shown in the figure below, β represents the horizontal position of the antenna installation, and its accuracy is directly related to the target area that the antenna wants to cover.

In general, the downtilt angle and horizontal angle of the antenna are directly related to the target coverage area of the antenna. If there is a deviation from the target, the performance of the wireless network will be degraded, such as mobile phone users cannot communicate, the signal is weak, or the interference is too large.

As mentioned above, base station antennas are installed in high, open and unobstructed locations, so they are easily affected by storms and typhoons. The device for fixing the antenna, such as the antenna pole, including the physical information of the antenna itself (azimuth angle, downtilt angle) will change under these circumstances. For example, after a typhoon in a coastal area, the coverage and quality of the wireless network deteriorate due to changes in the orientation information of the antenna.

At present, to correct these effects, maintenance personnel need to go to each site to check whether there is any antenna abnormality, such as going up the tower or going to the roof to measure with instruments. If abnormalities are found, they must be corrected at the site, and then record the antenna downtilt and horizontal azimuth angle information. These processes require a lot of cost, including human and material costs.
