摘　　要：SimpliciTI协议是美国TI公司推出的针对简单小型RF网络的专有低功耗协议.在Keil MDK 3.8开发环境下移植SimpliciTI网络协议,设计一种无线传感器网络系统,系统包括中心节点和终端节点.该系统以单片机STM32F103C8作为微处理器,通过控制射频收发芯片ADF7021进行数据的收发.通过对SimpliciTI网络协议及其拓扑结构进行了分析,并在此基础上设计低功耗和载波侦听退避算法,最终实现了基于SimpliciTI协议的无线传感网系统,可用于单数据采集中心和多个传感器节点的场合.SimpliciTI network protocol, the low power RF protocol aimed at simple and small-scaled RF network is issued by America TI company. It is transplanted to design a wireless sensor network system in Keil MDK 3.8 software development enviroment。 The network system includes acess point and end device. In this system, STM32F103C8 is adopted as the microprocessor, coordinating with its ADF7021 wireless transceiver; the node hardware system is composed. SimpliciTI network protocol and its topological structure are analyzed and the software is designed based on the low power consumption design and carrier sense backoff algorithm. Thus, the network communication system based on SimpliciTI network protocol is implemented, which can be applied in single data collection center where the multiple sensor nodes.
