摘要
现有常规CTD采水器测控系统自动化程度低、操作复杂。为此,基于LabVIEW软件开发了深海气密采水器测控系统,研究温度、盐度和深度测量原理,进行测控系统的硬、软件设计。2009年该测控系统在我国"海洋四号"科考船"HY4-2009-2"航次中成功应用,在中国海南试验中实现对深海气密采水器的快速、精确控制,并实时进行温度、盐度和深度等参数的采集、处理、显示和存储。海上试验表明,该测控系统具有测量与控制精度高、运行稳定可靠、自动化程度高、操作简便等特点,获得科研人员较好评价。该方法可推广到其他海洋仪器、设备的测控系统中应用。
The measurement and control system of exiting conventional CTD sampler suffers from low automation level and complicated operation.In order to solve this problem,a measurement and control system based on LabVIEW for gas-tight deep-sea water sampler was developed.The measurement principle of temperature,salinity and depth was studied.The hardware and software of the system were designed.In the year of 2009,the measurement and control system worked well during the HY4-2009-2 cruise of ＂Hai Yang Si Hao＂ research vessel in South China Sea.Quick and precise control of the gas-tight deep-sea water sampler was achieved.The acquisition,processing,display and storage of temperature,salinity and depth parameters were implemented conveniently in real-time.The results of sea trials show that the system features high measurement and control precision,good stability and reliability,high automation level and easy operation.The system is appreciated by researchers.Furthermore,the proposed method can also be used widely in the measurement and control systems of various oceanic instruments and equipment.
