摘要
为建立赤潮监测机制,设计一种集海水采样、试剂抽取、化学反应、吸光度测量、管路清洗的全自动海水营养盐分析系统。该工控系统基于PROFIBUS—DP现场总线进行网络通信,上位机采用嵌入式WinCE操作系统和MCGS嵌入式组态软件,下位机采用PLC控制,利用模糊控制的方式,大大提高海水营养盐自动分析仪的测量精度和可靠性,满足海上分布系统现场监测的要求。
For prediction of red tide, an auto analysis system of seawater nutrients was designed, which simultaneously combined the functions of sampling seawater and reagent, chemical reactions, measuring absorbance of samples, and cleaning pipes. Based on PROFIBUS - DP, embedded WINCE OS and MCGS, and PLC controlling system with fuzzy logic technology, the accuracy and reliability of the auto analysis system were greatly improved. The requirements for in -situ monitor were fully satisfied.
