月面灵巧探测网络系统设计探讨

Discussion on Design of Lunar Dexterity Detection Network System

针对月球广覆盖、长时连续探测的需求,提出了一种基于无线传感网络的月面灵巧探测网络系统。该系统以低功耗探测器作为感知节点,基于LoRa技术构建月面分布式探测网络,通过容器技术封装上层信息处理流程,实现月面探测数据实时处理。仿真选取了月球南半球一块面积为23350 m×58300 m的典型区域,搭建了月面灵巧探测网络的地面演示系统,模拟了环境检测数据的采集与实时处理过程。仿真结果表明:当移动接入点M-AP节点数超过46时,其覆盖率能够达到100%,且总趋势大致呈线性上升,验证了月面分布式通信组网、数据实时收集处理方案的可行性。

To satisfy the needs of wide coverage and continuous long-term exploration of the moon,a lunar surface dexterous detection network system based on wireless sensor network was proposed.The low-power detectors were used as the sensing nodes in the system.Then a lunar surface distributed detection network based on LoRa was built and the upper-level information processing process was encapsulated through the container technology.Thus,the real-time processing of lunar surface detection data was realized.A typical area of 23350 m×58300 m in the southern hemisphere of the lunar surface was selected for simulation and a ground demonstration system for the lunar surface dexterity detection was built.The collection and real-time processing of environmental detection data was simulated and the results showed that the coverage rate reached 100%when the number of Mobile-AP nodes exceeded 46,and the general trend showed a roughly linear increase.The experiment verified the feasibility of the lunar surface distributed communication network and the real-time data collection and processing scheme.
