基于无线传感器网络的水产养殖水环境监测系统设计与试验

Design and test of aquaculture water environment monitoring system based on wireless sensor network

为满足水产养殖水环境实时监测的需求,研究设计了基于无线传感器网络的水环境监测系统,传感器采用Modbus RS485协议,使系统具有很强扩展性;软件设计采用休眠和数据融合技术,降低了系统功耗。在太平池水库选取两个区域内针对无线传感器网络监测的水环境的pH值和DO值与常规方法监测的参数进行对比,pH值的相对误差分别为2.03%和1.84%;DO值相对误差为0.6294%和0.63%,测量精度可以满足湿地水环境的应用要求;系统运行期间数据正确传输率为98.89%。

In order to meet the demand of aquaculture water environment real-time monitoring, the water environment monitoring system based on wireless sensor network was studied and designed. By using Modbus Rs485 protocol, this system has strong scalability. The software design used the dormancy and data fusion technology to reduce the power consumption. According to water environment of wireless sensor network monitoring, two regions＇ pH and DO in Taiping Chi reservoir were selected to compare with the parameters of conventional methods monitoring, the relative error of pH was 2.03% and 1.84% respectively, and the relative error of DO value was 0.6294% and 0.63%. The measurement accuracy can meet the application requirements of aquaculture water environment. During system operation, the data transmission correct rate was 98.89%.
