摘要
该文设计了一种基于SimpliciTI协议的无线传感网络系统,传感器节点以MSP430单片机和射频芯片CC1101为核心,并辅以温湿度、光照、红外等传感器。节点使用随机物理地址,网关采用基于ARM9的嵌入式处理器AT91SAM9261。运行在网关上的上位机可以实时观察节点采集的数据并加以控制。实验结果显示,基于协议的该系统稳定性高。外部数据也可通过串口接收,系统具有良好的可移植性。
This paper designed a wireless sensor networks based on SimpliciTI protocols.The sensor node mainly uses MSP430 and CC1101 RF chip,supplemented by temperature and humidity,light,infrared and other sensors.Nodes use random physical address while the gateway uses ARM9 based embedded processor AT91SAM9261.Within PC running on WinCE OS,it could watch real-time data collected from nodes and do controls.Results show that the stability of the system based on the protocols is high.External data can also be received via the serial port,thus,the system has good portability.
