Problems solved by technology

However, the downtilt adjustment method of this multi-frequency multi-port antenna requires multiple downtilt adjustment devices, which leads to a large overall size of the antenna downtilt adjustment device, which cannot meet the development trend of miniaturization, and the reliability is also greatly reduced.

Abstract

The invention provides a two-driving-many transmission device and an antenna inclination angle control system. The transmission device comprises two driving shafts, that is, a first driving shaft anda second driving shaft; two gear assemblies, that is, a first gear assembly and a second gear assembly; and a driving device and output mechanisms. During use, the driving device drives the first driving shaft and the second driving shaft to rotate; the first gear assembly can engage one or more output mechanisms; the driving device drives the second gear assembly to rotate through the second driving shaft, and the second gear assembly can drive the output mechanisms engaged with the first gear assembly; and the output mechanisms are connected with phase shifters to drive the corresponding phase shifters to adjust the downward inclination angle of an antenna. The two-driving-many transmission device and the antenna inclination angle control system can realize inclination angle control of two or more than two beam antennas, and meanwhile, realize modular installation, maintenance and replacement, reduce size and cost, and improve reliability of the antenna control system.

Description

technical field [0001] The invention relates to the technical field of mobile communication equipment, in particular to a two-drive multi-transmission device and an antenna inclination control system. Background technique [0002] With the continuous increase of mobile communication terminal users, the demand for mobile communication network capacity is increasing. At the same time, the interference between sites and sectors is required to be minimized to maximize network capacity and minimize interference. It is realized by adjusting the downtilt angle of the beam of the site antenna. [0003] In mobile communication systems, there are currently two commonly used methods for adjusting the downtilt angle of the antenna: manual adjustment and electric adjustment. Compared with manual adjustment, electric adjustment has the advantage that it does not need to manually climb the tower, and does not need to operate at the antenna end, which is very convenient and easy to impleme...
