摘要
目前规模化水产养殖场地域范围广,为了解决其带来的监控系统复杂、设备以及线路安装不便、数据传输误码率高等不利情况,将无线传感网络引入到系统中,采用了簇状网络拓扑结构,通过修改LEACH路由协议,实现固定路由节点设置,实现了节能目的。通过对池塘水体的检测分析得出水体空间上环境因子的分布情况,并根据分布情况确定了传感器节点的数量与位置,从而完成了无线传感网络的构建。试验表明,数据在无线传感网络内传输误差安全可靠,能够满足规模化水产养殖大量数据传输的需要。
A wireless sensor network for aquaculture on a large scale was constructed, aiming to avoid the negative effects brought by the large scale; and improve the accuracy of the transmission of the environmental factors of aquaculture in network. The topology of cluster was set and a fixed cluster head was also set in every cluster by properly modifying rou- ting protocol of LEACH to achieve saving energy. The distribution of water quality in horizon and in vertical was studied and the number of sensor node and the location of sensor node were decided according to the distribution of water quality. Further experimental tests showed that communications among the system ware realized reliably. The application of the system can well meet the demands of transmission of large number of data in aquaculture on a large scale.
