摘要随着科学技术的发展，以及陆地资源的逐渐匮乏，人们不避免的将视线转向了海洋。要想利用，就必须先要探测海洋。想要探测海洋，就必须先测量其最基本的参数情况。

本次设计根据实际需求出发，设计海水的温盐深传感器。分析了国内外关于海洋探测的发展现状以及该项技术在未来的发展设想，并在原本的实际运用的情况下加入自己的创新。本次设计测量的是海水的温度盐度以及深度，分析论证了各个传感器的选择与之间的优缺点，设计调理电路，使得原本微弱的信号能够检测并且被放大测量出来。并且通过数据采集、A/D转换、JTAG接口电路等模块的设计使得数据被采集。选用功能强大的MSP430F169芯片对所测参数进行处理。为了更加清晰观测到海水的参数变化，提供及时的数据，采用PC机作为上位机，应用LabVIEW虚拟技术开发平台，LabVIEW具有操作方便，功能强大，设计简单等优点，适合作为本设计的上位机检测。69235

The Design of CTD Sensor

Abstract

With the development of science and technology, as well as the gradual lack of land resources, people do not avoid the sight to the ocean. If you want to use, you must first detect the ocean. If you want to detect the ocean, you must first measure the most basic parameters.

This design according to the actual demand, the design of the sea water temperature salt depth sensor. The development status of ocean exploration at home and abroad, as well as the development of the technology in the future are analyzed, and in the actual use of the original to add their own innovation. The paper design through the main parameters of temperature, salinity, depth sensor probe measure sea. Analysis proves that the selection of each sensor and between the advantages and disadvantages, conditioning circuit design, making originally weak signal capable of detecting and is amplified and measured out. And through the data acquisition, A/D conversion, JTAG interface circuit and other modules of the design so that the data is collected. MSP430F169 chip with powerful function is used to deal with the measured parameters. In order to more clearly observed change of parameters of the seawater, providing timely data, using PC as the host computer, using LabVIEW development platform, the collected data storage, display, convenient for human-machine interaction. The utility model has the advantages of high reliability, low cost, multiple functions, convenient installation, strong practicability, etc..
