船载水样自动采集系统
|
摘要
为了适应我国近海海洋环境监测快速、多要素的现场监测需求,研制了一套船载水样自动采集系统,系统控制方式简单灵活,具有全自动、半自动和手动三种控制模式。该系统由采水泵、复合采水缆、电动绞车、电控柜、储水罐等硬件和控制软件组成。在软件的控制下,绞车、采水泵等执行元件可自动开启和关闭,自动完成同一地点不同深度的多层水样采集。与传统人工采水方式相比,可大大减轻实验人员的劳动强度,减小水样采集的深度误差。渤海和东海大量的海上试验证明该系统性能稳定,能够适用于营养盐分析仪对水样的要求。
In order to meet the requirements of fast and multi-factors monitoring of the marine environment,a kind of shipborne automatic sampling system(SASS)was developed.SASS has a simple and flexible operation system,and has three control modes:automatic,semi-automatic and manual mode.The hardware of SASS mainly consists of pump,composite cable,electric winch,electric control cabinet and storage tank.With the control of the software,the devices such as winch and collecting pump can open and close automatically,to complete the collection of multi-level seawater samples in same site.Compared with the traditional method,this system can greatly reduce the labor intensity of the experimenters,and improve the precision of sampling depth.After a large number of sea trials in the Bohai Sea and in the East China Sea,SASS has been proved to be stable.
