摘要:
潜标是海洋环境监测中最可靠、最准确的手段之一,潜标工作于水下,测量水下参数,可以与海面浮标形成互补,实现对海洋环境的立体观测。深海海洋动力环境预报与海洋军事环境的保障需要实时资料的支撑,大力发展准实时定点连续观测系统是必要和急迫的。基于此,开展国产深海准实时传输潜标系统的设计,重点进行锚泊系统水动力分析、观测设备工作同步性、准实时通讯系统安全可靠和系统低功耗等整体设计技术优化;开展轻型感应耦合传输缆制作、大深度感应耦合传输和智能收放通讯等数据实时通讯技术的研究;进行适用于准实时传输潜标系统的多种类国产设备的稳定性和可靠性优化、规模化集成和系统化的应用示范。研制相关国产部件和设备,进行系统集成测试和海上布放应用,形成半潜升降式准实时通讯潜标与浮子式准实时通讯潜标各1套。设计的准实时传输潜标系统集成1台抗污染CTD、19台感应耦合CTD、8台感应耦合T、4台感应耦合传输的ADCP、2台单点海流计和6台感应耦合数据传输仪,并配有2套声学释放器;潜标系统本体设计含有3个水下流线型浮体、1套通讯浮子、准实时卫星通讯装置(半潜式水下绞车或海面浮子)、10套以上深水浮球和1套锚泊缆系,可实现深达2000米的剖面温盐深和海流等海洋要素的高频率、多要素、多层次的长期连续观测和数据准实时传输,以便对科学问题解决和海洋环境安全保障等提供及时的数据支撑。

Abstract:
One of the most reliable and accurate methods to monitor the marine environment is ocean submerged buoy. The submerged buoys work underwater and measure underwater parameters, complementary with sea surface buoys to achieve stereoscopic observation of the marine environment. Deep-sea dynamic environment forecast and marine military environment safeguard need real-time data, which makes it necessary and urgent to develop a kind of quasi-real-time fixed-point continuous observation system. For this reason, we decided to design the domestic deep-sea quasi-real-time transmission submerged buoy system. We focus on the hydrodynamic analysis of anchoring system, the work synchronization of observation equipment, the optimization of overall design technologies such as safety and reliability of quasi-real-time communication systems and low system power consumption. We will carry out the research data real-time transfer technologies such as light inductively coupled transmission cable manufacture, large depth inductive coupling transmission, intelligently receiving and releasing communication, and we will also carry out their applications in deep sea to test their stability and reliability. Through this we can develop the related domestic components and equipment, carry out system integration testing and marine deployment applications, manufacture a set of semi-submersible lifting quasi-real-time communication submerged buoys and a set of float quasi-real-time communication buoys. The quasi-real-time communication submerged buoy system integrates 1 anti-pollution CTD, 19 inductively coupled CTDs, 8 inductively coupled Ts, 4 inductively coupled transmission ADCPs, 2 single-point ocean current meter, 6 inductively couple data transmission instruments, and 2 sets of acoustic release transponders; the body of submerged buoy system contains 3 underwater streamlined buoys, 1 set of communication floats, quasi-real-time satellite communication device (semi-submersible underwater winch or sea surface float), 10 or more sets of deep-water floats and a set of mooring system. The deep-sea quasi-real-time communication submerged buoy system can achieve high-frequency, multi-element, multi-level long-term continuous observation data such as temperature and salt depth and ocean currents at a depth of 2000 meters which will be transferred to shore based lab in quasi-real-time, which can solve scientific problems and provide timely data supported for the marine environment safety guarantee.
