智能船舶中环境对WSN影响分析与优化对策

Analysis of the influence of intelligent ship environment on WSN and optimization countermeasures

根据CCS《智能船舶规范》,分析了智能船舶WSN的应用特征及现状。根据电磁波传输理论,建立了"白盒"、"黑盒"、"窗口"、"反射"、"衍射"、"地面"6种静态组网模型;根据WSN应用,建立了"微微网"、"散射网"和"混合网"3种动态组网模型,系统地将整个船舶归纳为8种典型环境,并对此环境下智能船舶WSN节点的布局给予了优化方案。

According to China Classification Society Rules for Intelligent Ships, in this paper we first analyzed the cur- rent application characters of Wireless Sensor Network （WSN） for intelligent ship. Then we established six types of static network model based on the theory of electromagnetic wave transmission, which are no-box model, closed-box model, open- box model, reflection-interference model, diffraction-interference model and ground-interference model. Furthermore, we de- signed three types of dynamic network model based on the application of WSN, which are piconet, scattemet and hybrid net- work. Finally we showed that a whole ship can be systematically classified into 8 typical environments and suggestions for the optimization layout of intelligent ship WSN nodes were given.
