无线传感网技术在水产养殖环境参数监测中的应用

针对国内水产养殖存在的在线监测系统受到现场条件限制,检测点不易更改和扩充,在恶劣和危险环境难以推广等问题,基于低功耗ZigBee CC2430无线通信技术设计一个水产养殖环境参数监测系统。对传感器节点进行设计,对养殖环境信号的采集、处理方法进行研究,为ZigBee网络降低了数据流量,在此基础上组建Zig-Bee网络,用于数据传输。该系统采用星型拓扑结构组网,通过在监测区域部署网络节点,以ZigBee CC2430芯片为核心控制单元的传感器网络节点实时采集水体温度、溶氧量浓度和pH值等环境数据,将监测数据汇集到监测中心,实现统一的数据管理和网络路由监测功能。试验证明,该系统稳定性好,数据传输可靠性高,通过增加数据采集频率,减少了数据丢包率,适用于不便直接连线的水产养殖环境监测场合应用。

Application of Wireless Sensor Network Technology in Environmental Information Monitoring System of Aquiculture

Focused on the limit of field condition,change test points more easily,and popularize on-line condition monitor system in dangerous area in aquiculture of our country,in this paper,the environmental factors monitoring system of low-powerwireless communication technology based on ZigBee CC2430 was designed.First,sensor nodes design,aquiculture environmental factors signal acquisition and processing is researched to reduce the quantity of data.On the basis of that,ZigBee wireless sensor network(WSN)is constructed for data transmission.By placing network nodes in monitoring area,the collection part based on ZigBee CC2430 digitalizes the signal from the sensor of temperature,dissolved oxygen and pH,and sends it out using wireless digital transmission technology.The system uses a star topology structure and the monitored data is converged to the monitoring center to achieve a unified data management and network routing monitoring.The test results have shown that this system has the properties of high stability,high reliability of data transmission,and reducing the packet loss rate by increasing the frequency of data collection,which are suitable for the aquiculture environmental monitoring occasions inconvenience to the direct connection.
