摘要
为满足水下滑翔器连续获取海洋剖面水文动力高质量数据的应用需求,利用自主研制的电磁感应式电导率传感器,集成快速响应的热敏电阻与压力传感器,以PIC 18F2520单片机为电路系统的核心控制器,设计出一种适用于水下滑翔器搭载的微型化、低功耗、重量轻的SZQ1-1新型CTD传感器.该CTD测量仪经实验室多次标定,数据质量达到海试要求.2016年10月,该CTD传感器与海鸟SBE19 Plus在青岛胶州湾进行了海试比测.海试结果证明,该CTD传感器与SBE19 Plus测量结果相近,实时获取的温、盐、深剖面数据精度满足水下滑翔器的搭载要求.
In order to meet the continuous measurement application demand of underwater gliders,and to obtain marine hydro-power high-quality cross-sectional data,a new miniaturization,low-power-consumption,lightweight SZQ1-1 CTD sensor has been designed in this paper for underwater gliders.The CTD has used the electromagnetic induction type principle to measure conductivity,integrated fast-responsed thermistor and pressure sensor,and is controlled by PIC18F2520 microcontroller in the circuit.The CTD measuring instrument has been calibrated many times in the laboratory,and the data quality is proved to meet the requirements of sea test.In October 2016,the CTD sensor was compared with SBE19 Plus of Seabird in the Jiaozhou Bay,Qingdao.Sea test results show that the the measurement results of CTD sensor are similar to those from the SBE19 Plus,and the accuracy of temperature,salt and depth profile data obtained in a real-time manner meets the requirements of the underwater gliders.
