水产养殖系统采用通用分组无线业务（ GPRS）和无线传感器网络（ WSNs）混合通信，利用各水质采集节点组成Zig Bee网络，让唯一具有GPRS功能的节点作为 Zig Bee网络簇头，并负责收集参数。当增氧机在时间间隔内没有收到控制命令时，簇头节点给终端控制中心发送一个触发信息，控制中心调用离线数据和养殖周期数据对增氧机进行控制判断，实现闭环控制，除簇头外，其余节点不直接和终端控制中心通信。通过对养殖池塘水质参数的实际监测表明：该混合通信模式提高了增氧机控制效率，减少了系统能耗。

Using general packet radio service( GPRS )and wireless sensor networks( WSNs )hybrid communication,use water quality collecting nodes composed of Zig Bee network,the only nodes with GPRS function as Zig Bee network cluster head,which responsible for collecting water parameters. When aerator does not receive control commands within time interval,cluster head node sends a calls information,control center calls offline datas and breeding cycle data to control aerator,which realize the closed-loop control. Except cluster head, the other nodes is not directly communicate with terminal control center. By actual monitoring on pond water quality parameters,the hybrid mode of communication increases oxygen machine control efficiency and reduces energy consumption of the system.
