Design and Case Analysis of Transmission Nodes in Offshore Observation Network

近海观测网的传输节点由浮标系统、系泊系统和水声通讯系统组成,其中系泊系统对设备的水声通讯能力影响显著。本文考虑北部湾具体海域情况,将系泊系统进行简化,建立锚链的垂直高度相对误差最小为目标的优化匹配的数学模型。通过求解非线性方程组,进行分层变量优化计算。

The transmission nodes of offshore observation network are composed of buoy system, mooring system and underwater acoustic communication system. The mooring system has a significant impact on the underwater acoustic communication capability of the equipment. Considering the specific sea area of Beibu Gulf, this paper simplifies the mooring system and establishes the mathematical model of optimal matching with the objective of minimizing the relative error of the vertical height of the anchor chain. By solving the nonlinear equations, the optimal calculation of stratified variables is carried out.
