摘　　要：为促进中国淡水珍珠养殖业由传统粗放模式向高效生态智能化改造升级,该研究针对珍珠蚌工厂化循环水养殖模式下的水质监控需求,开发了基于无线传感网络的分布式水质监控系统。系统采用感知层、传输层和应用层相结合的体系架构,由水质监测节点、气象监测节点、设备控制节点和监控中心组成。现场采用多参数传感器、ZigBee无线模块、可编程逻辑控制器(Programmable Logic Controller,PLC)和MCGS触控屏组合的方式,实现对多地点监测数据的实时采集、图形化显示和报警功能,对循环水处理设备的启停控制及藻类供饵自动控制功能;上位机采用MCGS网络版和SQL Server数据库构建监控数据中心。系统采用无线组网分布式架构,组网灵活且操作简单,简化了设备的安装和维护工作。经实际使用测试,系统工作稳定性和检测准确性均在98%以上,能够满足淡水珍珠蚌循环水养殖的监控需求,可以为珍珠蚌传统养殖模式的转变和产业生产方式的转型升级提供有利保障。In China,the freshwater pearl mussel aquaculture plays an important role in agricultural production.The freshwater pearl mussel’s growth process does not harm the environment,but the traditional aquaculture model has caused problems such as serious water pollution,eutrophication,and ecological environment destruction.Facing such a situation,it’s necessary to develop a new model for freshwater pearl aquaculture.This study showed a new industrialized circulating water aquaculture model(using multi-layer dimensional cages and feed pearl mussel with high-quality microalgae).Due to the high density of aquaculture,this model had very high requirements for water quality,so it was particularly important to monitor the circulating water quality.This study developed a distributed monitoring system for the water quality monitoring based on ZigBee wireless sensor network.The system used the three-layer architecture of the field sensing layer,transmission layer and application layer,and mainly included the following 4 parts:water quality monitoring subsystem,meteorological monitoring subsystem,equipment control subsystem,and monitoring data center.The system used the ZigBee module to set up the wireless transmission network,the advantage of this method was flexible networking and easy operation,and it simplified the installation and maintenance work.In the field scene,we set up multiple monitoring points in different places,multi-parameter water quality sensors were used to monitor key circulating water quality parameters(including temperature,pH value,dissolved oxygen,ammonia nitrogen,calcium concentration,and algae concentration),and meteorological parameters(such as temperature,humidity,barometric pressure,illumination,wind direction,and wind speed)were collected at meteorological station.All the sensors sent real-time detection data to their related ZigBee routers by RS485 protocol,and through the ZigBee wireless communication network,the data(including water quality and meteorological parameters)would be gathered in
