摘　　要：为克服目前海洋环境在线监测仪器设备在应用北斗卫星通信系统的区域限制和Argos卫星通信系统的实时性限制,设计了基于铱星通信系统,并应用于海洋环境在线监测的漂流浮标。浮标采用C8051F单片机作为控制核心,利用HD—2005型便携式χ-γ剂量率仪和海水温盐深测量仪等作为传感器,测量数据经铱星突发短数据终端模块9602上传至铱星通信系统指定邮箱,或反向传送控制命令。浮标通过海上模拟实验获得了较好的效果,初步证明了该设计方案满足低功耗实时传输海洋环境监测数据的要求。In order to overcome the area restrictions of beidou satellite communication system and the real- time constraints of Argos satellite communication system which are used in marine environment online monitoring instruments and equipment, a drifting buoy based on iridium satellite communication system is designed to conduct daily online marine environmental monitoring. A C8051 F MCU is used as control core in the buoy. The HD- 2005 portable χ- γ rays dose rate instrument and Conductivity- Temperature-Depth（ CTD） are used as sensors to monitor marine environment in real- time. The measured data is temporarily cached in the iridi-um Short Burst Data（ SBD） terminal block 9602 through the serial port and then the cached data in the terminal block is passed to the specified mailbox of iridium satellite communication system. What ′ s more, the instructions could be sent to the buoy through the terminal block by the monitoring center. Better result is achieved by the marine simulation experiment. The preliminary results demonstrate the initial design meets the requirements of low power consumption and real- time marine environmental data transmis-sion, with high reading success rate and good communication effect.
