海洋信息综合采集系统设计

Design of Marine Integrated Information Collection System

系统由数据采集节点、路由器节点和协调器节点构成,数据采集节点采用分布式自组织网络结构,实现对水体温度、pH值、溶解氧、电导率等水质参数的检测;路由器节点完成对水质参数无线传输平台的搭建,实现数据和命令的上传下达,并对系统的异常状态进行报警;协调器节点通过人机交互界面对数据进行处理、存储和分析,实现水质的远程监控。利用时间同步算法,实现全网节点的同步体眠和唤醒,大大降低了系统功耗。

The system mainly consisted of coordinator nodes,router nodes and data acquisition node.The Data acquisition node used distributed self-organizing network structure,it accomplished the detection of water temperature,pH value,dissolved oxygen,conductivity and other water quality parameters;the router nodes accomplished the wireless transmission of water quality parameters and the command data,it can alarm with the abnormal state;the coordination nodes accomplished the data processing,storage and analysis through the human-computer interaction community face,and realized remote monitoring and control of aquaculture water quality.The synchronization of the whole network node to sleep and wake up was realized using the time synchronization algorithm,it greatly reduced the system power consumption.
