摘　　要：为了解决常规水产养殖过程中人工成本高、数据采集误差偏大的问题,并实现及时了解关键参数空间分布情况,达到为水产养殖提供决策信息的目的,设计了基于无线传感器网络的水产养殖水质参数监测系统,该系统采用ZigBee无线通信技术构建传感器网络,主要监测水温、pH值、DO三种水质参数指标,并利用MATLAB平台,将卡尔曼滤波算法与线性内插值法相结合,实现水质参数的优化与空间分布四维模型的构建;通过选取分布空间中不同点的参数数据与实际测量的数据比较,温度、pH值和DO平均相对偏差分别为3.18%、2.89%、1.59%;研究结果表明通过卡尔曼滤波优化与线性内插值法构建空间分布模型,能准确掌握养殖池整体水质参数动态变化的信息,对养殖池的水环境管理有一定的参考价值。In order to eliminate the disadvantages of high costs on labor,the deviation of data measurement,and to achieve timely the spatial distribution of key parameters and achieve the purpose of providing the decision-making information for aquaculture,based on a wireless sensor network,the aquaculture water quality parameter monitoring system is designed,the ZigBee wireless communication technology is used to build a sensor network,mainly monitoring water temperature,pH and DO three water quality parameters indicators,by the use of MATLAB platform,the Kalman filtering algorithm and the linear interpolation method are combined to achieve the optimization of water quality parameters and the construction of a four-dimensional spatial distribution model.By comparing the parameter data of different points in the selected distribution space with the actual measured data,the average relative deviations of temperature,pH and DO are 3.18%,2.89% and 1.59% respectively.The results show that the construction of spatial distribution model by Kalman filtering optimization and linear interpolation method can accurately grasp the information of the dynamic changes of the overall water quality parameters of aquaculture pond,and can have a reference value for the aquatic environmental management of the breeding pond.
