Author(s): 
Pages: 61-67
Year: Issue:  5
Journal: Journal of Hechi University

Keyword:  无线传感器网络MSP430无线传输数据采集;
Abstract: 针对传统环境监测系统的不足,提出了一种基于无线网络技术的数据采集系统设计方案,并详细阐述了其硬件系统和软件系统的设计方法.节点以MSP430单片机为控制核心,发射电路采用具有开关状态的丙类放大电路,接收电路采用具有间歇工作状态的超再生检波电路;监测终端节点和传感器探测节点通信采用27.145 MHz载波、ASK调制方式,数据编码采用双相码,波特率为1 kbps,通信协议采用时间片分层的方式,实现了各节点双向高效通信.经测试,能够满足工农业现场环境检测及远程监控的要求,具有广阔的应用前景.
