工厂化水产养殖智能监控系统

采用PC工业控制计算机为上位监控机,以多个PLC可编程控制器和多个单片机系统为下位机,构成计算机集散监控系统.采用图像处理的方法对鱼病进行自动诊断和早期预报,采用移动GPRS无线通讯技术和互联网技术进行远程数据采集和监控.试验结果表明,该系统能对养殖水体的温度、氨氮含量、溶解氧含量等重要环境因子进行自动监测和控制,系统操作方便,人机界面友好,能在线进行鱼病诊断,使水产品能处在最适宜生长的环境下,达到增产、节能、减轻工人劳动强度的效果.

Research on intelligent supervising and control system of aquiculture

The distributed control system is presented which uses personal industrial computers as host computers and many S7-224 programmable logic controllers together with many single chip processors as subordinate computers.Image processing is introduced to automatically diagnose and predict the illness of fish.Remote sampling and control of data are realized by mobile general packet radio service(GPRS) telecommunication technology and Internet technology.The test results prove that this system can automatically supervise and control multi environmental factors such as the value of temperature,quantity of ammonia and nitrogen,dissolvent oxygen in pond and so on.Furthermore,this system can be operated simply and has a good interface.It can diagnose the fish's illness on line,which makes fish grow in the optimum environment.The whole system can improve production remarkably,save power energy and alleviate labor intensity.
