Abstract  

Neyman Pearson criterion was adopted to fuse the detection information from observation nodes. Specific conditions of grid sides were calculated when different unit grids met with full coverage. The structure of square and triangle unit grids under different circumstances was analyzed, based on the traditional method and detection information fusion, respectively. Then a node deployment strategy of cabled seafloor observatory network that based on the combination of square and triangle unit grids was proposed. The quantity and deployment location of primary and secondary nodes were ascertained, thus the specific structure of  network was determined. The specific deployment modes and requirements in different monitoring field were simulated. The results indicate that the scheme based on detection information fusion has  high covering efficiency,reducing the cost of network construction and the difficulty of installation and maintenance.

基于检测信息融合的缆系海底观测网络节点部署策略

采用Neyman Pearson准则融合观测节点的检测信息,计算当不同单元网格达到全覆盖时,网格边长应满足的具体条件.分析基于传统方式与基于检测信息融合的正方形和正三角形网格在不同情况下的具体结构,提出正方形和正三角形网格单元相结合的缆系海底观测网络节点部署策略,确定水下主、次节点的数量及部署位置,以及网络的整体结构.对不同监测范围内网络的具体部署方式与需求进行仿真计算.结果表明:与传统网络结构的节点策略相比,基于检测信息融合的部署覆盖比率高,部署节点数量少,盖效率较高,优势明显.
