一种WSN网关节点的设计与实现

无线传感器网络WSN是由分布在给定区域内大量无线传感器节点构成的一种新型信息获取系统,而无线传感器硬件节点的设计与实现是其应用的关键和基础工作.针对将无线传感器网络应用在青藏铁路沿线多年冻土区典型段进行地温、变形监测方面的特殊要求,设计了一种无线传感器网络系统,该网络由大量普通传感器节点、若干网关节点及一台计算机构成.无线传感器节点布撒在需要监测的区域内.将所探测到的有用信息通过初步的数据处理和信息融合之后,通过相邻节点接力的方式传送给网关节点.网关节点通过无线方式接收各传感器节点的数据并以有线的方式将数据传送给最终用户计算机.本文详细介绍了一种基于CC2431的网关节点以及基于C8051F320的USB接口的软硬件设计与实现.

Design and Implementation of Sink Node for WSN

WSN is one of novel information acquisition system,which consists a large number of distributed tiny sensor nodes. The design and realization of WSN node are the key and foundation work for its application. In view of the special request which WSN is applied in the safety supervision of Gulmud-Lasa line in Qinghai-Tibet railway, we have designed one wireless sensor network system,which consists of many ordinary sensor nodes and sink nodes and one computer. The WSN node is scattered in the region which needs to monitor. It will collect useful information and take data processing and fusion and then transmit to the sink node through the neighboring node. The sink node receives various data acquired by sensor nodes through the wireless communication and transmits the data to the end-user computer by the wired way. This article proposes the design of sink node in WSN based on cc2431 and the USB inter face based on C8051F320 in detail.
