横摇倾角对浮标通信强度的作用机理研究

Research on effect mechanism of rolling tilt angle on buoy communication intensity

海上浮标受海浪影响,通信天线会产生横摇倾角,严重威胁着通信成功率。为提高浮标无线通信的成功率,保证数据传输的可靠性,通过分析浮标结构特性与我国海区波浪特性,建立浮标在海浪中的横摇模型,得出浮标在不同海况下的横摇倾角。通过结合浮标的横摇模型和电磁通信模型,在Unity3D平台中仿真获得了接收点场强随横摇倾角与通信距离的变化机理关系,仿真结果验证了分析的正确性,该研究可为浮标结构或通信协议优化提供具体参考指导,具有一定的实际应用价值。

The rolling tilt angle will occur to the communication antenna when buoys on the sea are affected by waves,which seriously threatens the success rate of communication.In order to increase the success rate of buoy wireless communication and ensure the reliability of data transmission,the buoy structure characteristics and the wave characteristics of the sea area in China are analyzed to establish a rolling model of buoy in the ocean waves,so as to obtain the rolling tilt angle of the buoy under different sea conditions.By combining the buoy′s rolling model and electromagnetic communication model,the relationship of changing mechanism that the field strength of the receiving point changes with the rolling tilt angle and the communication distance is simulated on the Unity3D platform.The simulation results have verified the correctness of the analysis,so this research can provide a specific reference for buoy structure or communication protocol optimization,and has a certain practical application value.
