摘要
运用低功耗Cortex-M3微控制器STM32L152和低功耗集成无线收发芯片SI4432设计了一种无线网络系统。介绍了系统的体系结构、硬件电路、数据的接收和发送流程,以及网络管理机制。系统运用了链路质量估计算法和硬件冗余技术,采用TinyOS系统的LEPS路由协议实现无线网络的构建和管理。
A wireless network system is designed based on the ultra low-power and Cortex M3 core STM32IA 52 and the low power intc grated wireless transceiver 814432. The system structure, hardware circuit and the software flow diagram of sending and receiving data are introduced. In the system, the link quality estimation algorithm and hardware redundancy is used. The system realizes the manage ment and the structure of the wireless network with the routing protocol LEPS in TinyOS.
