摘要
TinyOS具有代码开放、使用简单、可靠性高、实时性好等优点,是专门针对无线传感器网络节点设计的操作系统。设计了一种基于ZigBee协议的无线电力抄表系统,详细论述了基于MSP430F149内核的抄表采集器的硬件设计总体方案,TinyOS操作系统在该内核上的移植,以及ZigBee协议在该系统上的实现。针对主控芯片的硬件资源,提出了静态任务调度机制,提高了TinyOS的实时性能。本设计在实现了采集器各项功能要求的同时,降低了开发成本,保证了系统的安全性和可靠性。
TinyOS,which is a special operating system for WSN nodes,has a lot of advantages such as code source opening,using simply,high reliability,good real-time and so on.This paper proposes a new solution of power energy meter reading system based on ZigBee protocol.It particularly describes the hardware design based on MSP430F149,kernel transplantation of TinyOS operating system,and the realization of ZigBee protocol on this system.This paper suggests a static mechanism for task scheduling toward the hardware resources of master chip,which enhances the real-time performance of TinyOS.This design achieves the functional requirements of the collector as well as reduces developing costs and ensures security and reliability of the system.
