基于无线传感器的海水重金属监测系统

Sea Water heavy metal Monitor System Based on Wireless Sensor Network

针对海水重金属污染检测恶劣环境提出了基于无线传感器网络的实时在线监测方案;通过密集地部署多个传感器共同监测局部海域重金属污染物,数据经过微控制器处理,由nRF2401射频模块经过监测节点、网关发送到监测中心作为观测海水污染程度第一手资料;介绍了无线监测系统的设计方法,对它的整体方案设计、无线采集器硬件电路、无线WEB服务器的电路结构、系统软件编程设计给出了详细论述,该系统实现了监测节点无线网络化,客户端浏览实时,数据方便实用;模拟实验结果表明了系统的稳定性与合理性。

For the vile environment of sea water heavy metal index detecting raised a monitoring system based on the wireless sensor networks on-line real-time. Many sensors were deploied intensively in order to monitoring heavy metal pollutions, the monitioring data were processed by MCU and transmited to monitoring center by nRF2401 module from monitoring nodes. It is regarded as first information of observing sea water pollution level.Introduces a design method of wireless monitoring system.It elaborates the overall plan,the hardware circuit of wireless acquiring,the circuit structure wireless WEB server, the design of system software.This system realizes the energy-saving wireless network of monitoring nodes,and it is convenient for browsing real-time data by cliant.The simulation results show its validity and stability.
