Description

一体式温盐深流检测装置、系统及方法 技术领域
本发明涉及海洋环境监测领域，具体涉及一种一体式温盐深流检测装置、系统及方法。
背景技术
海洋海水温度、盐度、深度和流速流向观测参数，是海洋观测中最基本的重要参数之一，对于海洋环境观测预报、防灾减灾、海洋开发、海洋科学研究等具有重要意义，随着国家海洋强国战略的实施，除了单点的海水温度、盐度、深度和流速流向观测之外，大深度海洋剖面的温度、盐度、深度和流速流向观测越来越受到国内外海洋学者的重视。
目前，海洋剖面观测中，温盐深剖面和海流剖面观测是完全独立的两套设备，温盐深剖面采用不同深度上布设一系列温盐深(CTD)传感器组成温盐深链进行，海流剖面观测采用多普勒声学海流计(ADCP)进行几百米深度范围的海流剖面观测，由于两者是完全独立的，时间上，两者难以同时，空间上，两者观测很难在同一深度层面上，这是因为ADCP利用的是声学多普勒原理，装在浮标上向下发出声波，根据回波多普勒原理，进行不同深度如2米、4米、6米等的流速流向观测，用一台设备即可进行剖面观测；而温盐链，是需要不同层上都安装一台CTD进行观测，所以难以在同一层面、同一时刻进行温盐流的观测。虽然ADCP利用声学多普勒原理，具有一台设备就可以进行海流剖面观测的优势，不过，受声波能量和观测精度限制，目前实际应用中，ADCP观测深度大约只有5～6百米，观测层数30～40层左右；而且ADCP基本都依靠进口，供货周期长，价格也非常昂贵，每台数十万，国外进口CTD价格在十几万左右。通过以上分析可知，目前的方式难以实现对海洋水体的同一层面、同一时刻的温度、盐度、深度、流速、流向的精细化观测，难以满足现代海洋高时空分辨率、高精度海洋环境观测的需求。
发明内容
本发明目的是提供一种一体式温盐深流检测装置、系统及方法，能够同时获取同一水团的海水温度、盐度、深度和流速流向参数，便于精细化观测，以克服现有技术的不足，而且体积小、功耗低。
一种同步、原位观测温盐深流剖面的方法，其特征是利用CTD链作为搭载平台，在该CTD链的指定CTD上安装单点海流计，形成一体式温盐深流检测装置，将所得到的安装有单点海流计的CTD链按照常规的布放CTD链的方式布放到所需海域，启动CTD链与其上的单点海流计进行观测，从而在得到温盐深参数的同时，得到单点海流计所在位置的海流剖面参数。
一种同步、原位全剖面观测温盐深流的方法，其特征是利用CTD链作为搭载平台，在该CTD链的每一个CTD上安装单点海流计，所形成的装置称为CTDC链，将该CTDC链按照常规的布放CTD链的方式布放到所需海域，启动CTD链与所有单点海流计进行观测，从而在得到温盐深参数的同时，得到海流全剖面参数。
一体海水式温盐深流检测装置(CTDC)，包括CTD，其特征在于还包括单点海流计，所述的单点海流计设置在所述的CTD上。
一种一体式海水温盐深流检测装置，包括带有上、下端盖的、内含电路板和电池仓的密封舱，
其特征在于还有温度传感器、电导率传感器、压力传感器和单点海流计，所述三种传感器的采集处理电路集成于所述电路板上，所述单点海流计的采集处理电路也集成于所述电路板上，温度探头、电导率探头、压力探头和单点海流计探头均安装在所述下端盖上；所述上端盖的外端面上还设有用于进行数据耦合传输的磁环。
所述的单点海流计1可以是电磁感应海流计也可以是单点声学海流计。
所述下端盖的外端面上还设有水密插头。
在温度探头和电导率探头外部设置保护罩，所述保护罩固定在所述密封舱上。
所述上端盖的一侧还设有包塑钢缆孔，且单点海流计探头1的轴线与包塑钢缆孔的轴线、密封舱的轴线不在同一个平面。
一种温盐深流检测链(CTDC链)，其特征在于包括多个以上所述的一体式温盐深流检测装置，和包塑钢缆，所述的一体式温盐深流检测装置通过包塑钢缆孔而依次安装在所述包塑钢缆上。
基于一体式温盐深流观测装置的海洋剖面观测浮标系统，包括通信卫星、岸基接收站、浮标，其特征在于还包括一体式温盐深流检测链(CTDC链)，所述包塑钢缆上端连接于浮标底部，下端则连接有缆绳，所述缆绳下端为锚链，所述包塑钢缆底部或缆绳上还设有浮球。
发明优点
目前，海流观测方法大致可分为机械海流计、电磁海流计、声学多普勒海流计及声学时差海流计4类，其中电磁海流计以其结构原理简单、检测精度高、使用方便、价格便宜、体积小等优点成为单点海流检测中的主力。
因此，提出一种温盐深流一体化的测量方法和仪器装置，利用电磁法海流测量精度高、体积小的特点，结合高精度CTD，将其两者高度集成融合为一体，实现单点的高精度温盐深流的“同时同地”(同一时间，同一层深)观测， 再将一体式温盐深流传感器按照不同深度布设成链，实现海洋温盐深流剖面观测，不仅有效克服传统方法温盐深和海流不能“同时同地”的难题，而且层与层之间间隔也可以很小，克服传统ADCP层数受限的不足。
本发明使用的温盐深流剖面观测链可根据实际需要来设置，长度可达上千米，远超传统的ADCP所能观测到的深度。
本申请具有以下显著优点：
1、创新性的提出温盐深流一体化设计思路，可以同时测量同一小水体的温度、盐度、深度、流速、流向参数，为精细化检测提供了一条可行路径。
本申请首次提出了CTDC的概念，正如CTD已成为行业内的标准化产品一样，在本申请的技术构思下，CTDC也有望成为行业标准化术语。
海洋剖面一般是指温盐深流，而CTD只能测量其中三种，只有本发明的CTDC能够实现对于温盐深流的同步检测，因此CTDC在一定程度上取代CTD也是未来的趋势。
2、将温度、电导率、压力和海流探头集成一体，可以实现供电和部分电路的复用，便于控制和降低功耗。
3、利用电磁法海流测量精度高、体积小的特点，结合高精度CTD，将其两者高度集成融合为一体，实现单点的高精度温盐深流的“同时同地”(同一时间，同一层深)观测，再将一体式温盐深流传感器按照不同深度布设成链，实现海洋温盐深流剖面观测，不仅有效克服传统方法温盐深和海流不能“同时同地”的难题，而且层与层之间间隔也可以很小，克服传统ADCP层数受限的不足。
4、本发明可采用国产化温盐深流传感器，因此价格更加低廉，更重要是实现温盐深和海流同时同地原位高精度观测，即不但降低了生产成本，还显著提高了检测效果。
