【摘要】：本文以国家863主题项目“深海滑翔机研制及海上试验研究”中声学滑翔机系统研制和深海滑翔机海上实验研究为研究背景。该滑翔机系统包括三个分系统：声学探测分系统、水下滑翔机分系统和岸站分系统，他们通过一体化设计构成有机整体，，完成海洋观测和声学探测的任务。本文着重对水下滑翔机和岸站分系统中铱星通讯部分进行深入研究和设计，主要包括铱星通讯系统结构设计、通讯协议制定、通讯模块与天线一体化装配设计、铱星通讯信号强度分析、远程控制基站构建等内容进行深入研究，最终完成科学的设计方案。在硬件设计方面：对铱星通信核心部件ISU（通讯模块）的性能进行深入的对比分析并选择恰当模块；按ISU电源和工作频率等参数要求，选定STM32-107作为主控芯片，设计远程控制板，配合水下滑翔机主控板完成远程控制和数据传输等任务；在岸站控制平台的通讯系统设计上，将由ISU引出的数据线采用RS485转接延长的设计方案，从而延长了平台和通讯部分的距离，便于平台建设。在软件设计方面：设计了远程控制指令体系，并参照美国无人机路线图对自主水平等级的评估方法，对该体系设计不同的优先级别；为保证远程控制稳定、通畅、灵活，设计了本课题水下滑翔机铱星通讯系统通讯协议；同时为便于岸站控制人员方便操作，设计了“中国海洋大学声学滑翔机操控平台人机界面”。经过多次湖试和海上实验以及对海量数据的处理分析，这些设计方案得到了充分检验和肯定。同时使水下滑翔机的工作稳定性、控制灵活性和准确性、信息采集系统和姿态调节系统的协调性、探测工作的长期性和周期性等性能得以显著提高，也为岸站操控的工作带来了极大的方便。
[Abstract]:The research background of this paper is the development of acoustic glider system and the offshore experimental research of deep-sea glider in the national 863 project "Deep-sea Glider Development and Offshore Test Research". The glider system consists of three subsystems: acoustic detection subsystem, underwater glider subsystem and shore station subsystem. This paper focuses on the research and design of Iridium satellite communication system in the subsystem of underwater glider and shore station, mainly including the structure design of Iridium satellite communication system, the design of communication protocol, the integrated assembly design of communication module and antenna, Iridium communication signal intensity analysis, remote control base station construction and other content in-depth research, the final scientific design. In the aspect of hardware design, the performance of Iridium communication core component ISU (communication module) is compared and analyzed deeply and the appropriate module is selected. According to the requirements of ISU power supply and working frequency, STM32-107 is selected as the main control chip to design the remote control board. Cooperating with the main control board of underwater glider to complete the tasks of remote control and data transmission, in the design of communication system of onshore station control platform, the data line derived from ISU is extended by RS485. Thus prolonging the distance between the platform and the communication part, facilitating the platform construction. In the aspect of software design, the remote control instruction system is designed, and different priority levels are designed according to the evaluation method of USA UAV roadmap to autonomous level level, in order to ensure the stability, smooth and flexibility of remote control, The communication protocol of Iridium satellite communication system of underwater glider is designed, and the man-machine interface of acoustic glider control platform of Ocean University of China is designed for convenient operation of onshore station control personnel. After many lake tests and sea experiments, as well as massive data processing and analysis, these design schemes have been fully tested and confirmed. At the same time, the performance of underwater glider, such as stability, control flexibility and accuracy, coordination of information acquisition system and attitude adjustment system, long term and periodicity of detection work, are improved significantly. It also brings great convenience to the operation of onshore station.
