摘要
为满足无人值守地区气象数据观测的业务需求,通过研究无线传感器网络和TinyOS,设计一种基于无线传感器网络的气象数据观测系统。该系统主要由数据采集层、数据传输层、数据处理层和信息发布层组成,其中采集层使用气象传感器完成对各气象要素的采集,传输层负责系统各节点间的数据传递,数据处理层和信息发布层是由嵌入式平台构成实现数据的解析、存储和信息发布功能。系统以无线方式部署并通过Web方式远程提供数据,有利于野外实施和维护,具有使用便捷、成本低廉、功耗低、数据通信稳定等特点。
In order to meet business needs of meteorological data observation in unattended areas, a system of meteorological data observation based on wireless sensog rletworks was designed through studying wireless sensor networks and TinyOS. The system consists of data acquisition layer, transport layer, data processing layer and layers of/etoased information. Acquisition layer uses meteorological sensors to complete the ac- quisition of various meteorological elements. The transport layer is responsible for transmission data between various nodes. Data processing layer and the information release layer composition is achieved by the ~dded display platform for data analysis, storage, and information dissemina- tion. System is deployed with wirelessly and provides data by web, It is conducive to the implementation and maintenance in the field and has ad- vantages in ease of use, low＇~cost, data communication, stability.
