摘要: |
海洋温度的变化会显著影响水下声传播、生物活动、气象和洋流等现象,温深是反映海洋变化运动规律的基本参数。投弃式温深剖面仪(Expendable Bathythermograph,XBT)、温盐深测量仪(Conductivity Temperature Depth,CTD)、全球海洋实时观测网(Array for Real-time Geostrophic Oceanography,Argo)等是目前进行海水温深测量的主要仪器。其中XBT因其现场测量简便、效率高、硬件成本低等特点,正在被大规模使用。本文主要介绍有关海洋温度测量的背景及演化历史,分析对比了国内外相关仪器设备的发展现状,总结了国产化产品还存在的差距和不足,另外对传感器、结构设计、数据通讯传输、数据后处理、可靠性研究等关键技术和研究热点进行了详细介绍,最后对未来无人平台的技术发展路线给出了思路和见解,开展投弃式温深剖面仪的相关技术研究和产品研制对实现国产化有积极的推动意义。 |

Abstract: |
The changes in ocean temperature will significantly affect underwater acoustic propagation, biological activities, meteorology, and ocean currents. Temperature and depth are the basic parameters reflecting the changes in ocean movement. Expendable bathythermographs (XBT), conductivity-temperature-depth profilers, and Argo floats are the main instruments for seawater temperature and depth measurements. Among them, XBT is used for large-scale measurements because of its simplicity, high efficiency, and low hardware cost. This paper mainly introduces the background and evolution history of ocean temperature measurement, analyzes and compares the development status of related instruments and equipment at home and abroad, identifies the gaps and shortcomings of domestic products, and introduces in detail the key technologies and research hotspots of sensors, structure design, data communication transmission, data post-processing, and reliability. Finally, the ideas and opinions on the future technology development route of unmanned platforms are presented. Technical research and product development of XBT need to be conducted to achieve localization. |
