Antenna adjustment system and base station

Abstract

The invention discloses an antenna adjustment system, which comprises a casing, an auxiliary board, an antenna fixed to the auxiliary board, an inertial feedback unit fixed to the auxiliary board, a controller, an actuator and an elastic element. The auxiliary plate is rotatably connected to the housing, forming a center of rotation at the rotatably connected place of the two. Both the actuator and the elastic element are connected between the shell and the auxiliary board. The inertial feedback unit is used for detecting the swing angle of the antenna and sending an angle signal to the controller when the antenna swings with the housing. The actuator and the elastic element are used to control the rotation of the auxiliary board in the opposite direction to the swing of the housing, so that the antenna fixed on the auxiliary board can counteract the deflection produced by the swing of the housing, and the actuator is driven by the controller according to the angle signal . The invention also discloses a base station. The invention can adjust the position of the antenna along with the swing of the antenna, and can ensure the stability of the signal transmission of the antenna.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a base station installed on a street light pole and an antenna adjustment system in the base station. Background technique [0002] With the popularization of smart terminals and the enrichment of mobile broadband services, the traffic of mobile networks in the future will continue to increase rapidly. To solve this problem, operators need to obtain more spectrum resources, improve spectrum efficiency, and increase cell density. network capacity. Base stations with small size, low power, and flexible deployment are the mainstream choice for increasing cell density in the future, and some small base stations are mainly installed on the exterior walls of buildings and street light poles, so as to better meet the mobile needs of users in hotspot areas. Broadband data service requirements. [0003] At the same time, considering that the main deployment scenario of the base s...

Problems solved by technology

[0003] At the same time, considering that the main deployment scenario of the base station is on the street light pole, the light pole on the street will be subjected to loads such as vibration, impact, and wind load fluctuation caused by heavy vehicles passing by, and these loads will inevitably cause the light pole to swing. The size of the swing angle is currently due to the different materials, processes and installations of the existing light poles. There is currently no unified standard and requirement in the industry. For example, the maximum deflection displacement of the street light poles in the UK is 5%, and the common domestic manufacturers are 2.5-5% (mainly based on the material yield strength. Considering the non-linearity of the light pole), through the measurement of the existing light pole, its maximum swing angle is much larger than the half-power angle of the microwave, which will cause the interruption of the return signal of the antenna adjustment system in the base station and seriously affect the signal transmission quality. Therefore, , the swing of the light pole caused by vehicles and wind loads will seriously affect the deployment of the base station equipped with microwave backhaul. There is an urgent need for an antenna adjustment system that can adjust the antenna emission direction with the swing of the light pole to ensure signal stability.
