Design and Implementation of Temperature and Humidity Acquisition System of Wireless Sensor Network

一直以来,低功耗以及远距离传输是无线传感器网络多点测量的两大不足,成为阻碍其进一步普及的瓶颈;利用无线传感网络分布式多点测量的特点,设计了基于IRIS节点无线传感网络的温湿度采集系统,介绍了系统整体框架和软件体系的设计及实现过程,并进行了温湿度采集实验;实验结果表明,节点可通过无线通信方式形成一个多跳的自组织网络系统,网络具有自愈功能,节点能够精确地采集和处理温湿度数据,节点间可以成功地进行通信,具有低功耗和远距离传输的优点。

Maintaining low power consumption and far transmission distance have been wireless sensor network multi--point measurements＇ two major weaknesses, and also become an obstacle for its further popularity. With the feature of distributed multi--point measurement, an acquisition system based on IRIS sense node which can measure temperature and humidity is proposed. The architecture of the system and the design of the software are introduced, and the acquisition test of temperature and humidity are done. Experimental results have shown that the nodes make up of a multi--hop self--organizing network through wireless communication, the network has a self--healing capabilities , the node can gather and process data effectively , communicate successfully between nodes, the system have the advantages of low power consumption and far distance transmission.
