摘　　要：针对目前我国工厂化海水养殖场现场控制设备技术落后,可靠性差的现状,本文提出了一种高性价比的集散控制系统。该系统以集散控制系统为设计思想,各个功能单元均以单片机为主控制器,针对各模块不同功能辅以不同硬件设计来实现相应功能,模块之间采用RS-485总线进行通信,并配有液晶显示,实时显示各种水质参数,方便操作员读取数据。试验表明集散控制系统稳定可靠,可以有效提高养殖池溶解氧含量达1mg/L以上,并有效减小溶解氧含量波动幅度。According to the conditions of poor control equipment and low reliability in China's aquaculture,the paper presented a distributed control system with high cost-effective.The each functional unit has a microcontroller.Each module was designed with different hardware to achieve the corresponding functions and RS-485 bus module was used for communication.The system can display in real-time with LCD for various water quality parameters and let operator real data easily.The experiment show that the distributed control system(DCS) is reliable and obviously to reduce the fluctuation of dissolved oxygen.The dissolved oxygen content of pond can be inereased by 1mg/L with the DCS.
