风振会造成基站天线安装位置产生相对位移,影响无线信号传播的多径相位,进而导致信号的传输损耗波动,出现网络覆盖盲区,针对基站天线风振响应数据采集需求,设计一种风振数据采集系统.系统使用ARM作为核心控制器,采用传感器模块获得天线所受的风振,通过采集板卡数据采集和无线数据传输模块以及云端服务器第1次实现基站天线风振数据的采集、传输与储存.经实际安装测试与数据分析,得到不同风速下基站天线的风振谱,为实验室环境下模拟天线受风振影响辐射性能指标动态变化打下基础,同时为挂塔天线安装可靠性风险控制、未来5G阵列天线(MIMO massive)结构设计、5G网络覆盖与优化提供重要原始风振数据.

Wind-induced vibration will cause relative displacement of base station antenna installation position, which can affect the multipath phase of the propagation and transmission loss of wireless signals. It can be causing blind area of radio networks coverage. For the date acquisition of wind-induced vibration,A data acquisition system for wind-induced vibration is designed. The system uses ARM as the core controller,the wind speed and vibration acceleration of the tower antenna are obtained by using sensors. The acquisition, transmission and storage of the wind-induced vibration data of the base station antenna are realized by using the data acquisition module, the wireless data transmission module and the cloud server. The wind spectrum of base station antenna under different wind speeds is obtained by data analysis. It lays a foundation for the dynamic change of the radiation performance of simulated antenna under the influence of wind vibration in laboratory environment. The system is used for reliability risk control of tower antenna installation and structure design of future 5G array antenna (MIMO massive) and it provides very important original wind vibration data for coverage and optimization of 5G network.
