基于北斗卫星系统的深远海GPS波浪浮标数据传输研究

Research on data transmission of deep and remote sea GPS wave buoy based on BeiDou satellites system

国家海洋技术中心研制的GPS波浪浮标仅需一个GPS接收机,无需其他辅助传感器,其功耗低、尺寸小、布放方便、测量精度高、适用于大范围的对波浪进行精细化观测。为了解决GPS波浪浮标在深远海应用中的数据传输问题,通过对比Argos、铱星、北斗三种卫星系统的特点,该设备优先选用了基于北斗卫星系统的数据传输方式。对系统构成、硬件电路设计、测量原理及数据传输流程分别进行了详细阐述。通过实验室实验和现场海上试验,特别是GPS波浪浮标在遭遇台风等恶劣环境下仍能正常通信,验证了北斗卫星系统在深远海数据传输上的可行与可靠性。

GPS wave buoy designed by National Ocean Technology Center just requires a GPS receiver without any extra sensors, it has characteristics of low power consumption, small size, easy to deploy, high measurement precision and suitable for wave measurement in large-scale and meticulous ways. In order to solve problem of deep and remote sea GPS wave buoy data transmission, by comparing characteristics of three kinds of satellites system of Argos, Iridium and BeiDou, this device gives priority to adopt BeiDou satellites system to transmit data. System constitution,hardware circuit design, measurement datas and data transmission flow are separately described in detail. Through laboratory and field test, specifically when GPS wave buoy is under the situation of harsh environment,such as typhoon,it is proved that the BeiDou satellites system can be used in deep and remote sea data transmission and its reliability is verifies.
