【摘要】 近年来,随着人类对海洋探索和研究的不断深入,人们对海洋数据采集传输技术提出了更高的要求。各种海洋环境参数传感器不断涌现,海洋数据传输则朝着全球性、全天候的实时数据收集方向发展。本文首先分析了海洋数据采集传输技术的现有技术和存在问题,从提高海洋数据采集传输系统通用性和实用性的角度出发,提出了基于铱星通信的海洋数据采集与实时传输通用平台的理念,该平台只需要通过软件参数的改变,就可以配合不同的海洋环境监测仪器,在不同工作模式之间灵活切换工作,从而满足用户对数据采集传输工作的不同需求。此外,通用的理念还体现在海洋浮标的单片机控制器,在加载uIP协议栈的基础上,能实现与提供不同应用服务的数据收集工作站进行实时数据通信。本文论述了基于铱星通信的海洋数据采集与实时传输通用平台的工作原理和技术要点,重点阐述了系统控制器的硬件和软件设计。设计中始终贯穿通用性和低功耗性的两大理念。硬件部分包括:电源管理电路设计、控制器与铱星终端及控制器与传感器的接口设计等;软件部分设计了一套不依赖于具体传感器和工作站服务类型的命令控制体系。本文设计的平台已应用于实现海洋数据的采集与远程实时传输,且在海试中取得了良好的效果,具有很好的应用前景。更多还原

【Abstract】 Recently, the development of ocean explorations and researches brings higher requirement to the technology of ocean data collection and transmission. Various kinds of marine sensors have come forth, and ocean data transmission is developing towards global coverage, all-weather capability and real-time transmission.By analyzing the present situation and existing problems of the technology of ocean data collection and transmission, a new concept of universal platform of ocean data collection and real-time transmission based on Iridium is raised. This concept aims to improve the universality and practicality of the system of ocean data collection and real-time transmission. The universal platform of ocean data collection and real-time transmission is compatible with different marine sensors, and flexibly shifts among different working mode of the marine sensor, so that different users’ demands on data collection and transmission can be fulfilled. Moreover, the concept of universality also lies in the compatibleness with work station of different application services for the MCU controller.In this thesis, the working principle and technical points of the platform is introduced, then the hardware and software design of system controller is emphasized discussing. The design follows two main principles: universality and low power consumption. The part of hardware design includes design for power management circuit, the interface design for MCU controller and marine sensor and the interface design for MCU controller and Iridium modem, etc. As for the software part, a command system which is independent of marine sensor and application services of remote work station is designed.Our design has been applied to the realization of ocean data collection and transmission. The platform performed well on the sea trial and has promising applications.更多还原
