文章总结了国内外水厂加矾控制系统的现状,针对其不足设计了一套基于图像处理的水厂加矾量自动决策系统。该系统硬件部分以PC为主控制器,外接视频监控系统及投药控制电路,系统软件部分以C++编程语言为基础,OPEnCV为图像处理和机器视觉库,开发出了基于MfC的软件系统界面。该系统可自动抓拍水质图像,对其进行相关图像处理后得到关键的水质参数,并根据水质变化适当自动地控制絮凝剂的投加量。The status of the auto flocculating agent adding system in waterworks at home and abroad is summarized.Aiming at its defects,a set of flocculating agent adding automatic decision system based on image processing is designed.The hardware part of the system uses PC as its main controller,circumscribed by video surveillance system and flocculating agent adding control circuit,while the software part of the system uses C++as its basis,OpenCV as the image processing and machine vision library,and the software system interface based on MFC is developed.This system can snapshot water quality pictures automatically,process the water quality pictures to get some critical water quality parameters,and control the flocculating agent adding properly and automatically according to water quality changes.国家自然科学基金资助项目(61001142); 厦门大学基础创新科研基金资助项目(中央高校基本科研业务费专项资金资助项目2011121050
