本文设计了基于无线传感器网络的鱼塘实时在线智能监控系统，有效解决了传统的鱼塘观测手段存在的问题，例如：费时费力、步骤复杂、成本高等。该系统在鱼塘的监测区域中利用无线传感器节点，测得该区域中的温度和溶氧量，并通过Zigbee网络将数据传输到终端控制系统，控制系统作出判断并发出报警信号和控制增氧机的状态。系统中以MSP430和XBEE模块为核心芯片，能够实时在线监测鱼塘中的一些参数，例如温度、溶氧量等。同时该系统还可以进一步扩展使用GPRS或3G网络实现远程监控。

In this paper, a real-time online monitoring system for fish ponds was designed based on wireless sensor networks to overcome the disadvantage of the observed of traditional means in fish ponds, such as time-consuming and laborious, step complexity and high cost. The system is integrated sensor modules and communication modules. In the monitoring area of fish ponds ,we could get temperature and dissolved oxygen by wireless sensor nodes, and used zigbee network data to transmit to the terminal control system.The terminal control system made judgments and sent alarm signal,at the same time controlled working condition of the oxygen machine. The system,which has MSP430 and XBEE moudle as the core chips,can real-time online and intelligently monitor parameters in fish ponds, such as temperature,dissolved oxygen and so on. Further that the system can be further expanded to use the GPRS or 3G networks to achieve remote monitoring and control.
