摘要
论述了Z igBee协议的原理及其帧结构,阐述了Z igBee协议的特点及其应用空间,论述了CC2420的组成、结构及控制方法,阐述了单片机MC68HC908W32的SPI通信模块的工作原理及控制方式,设计了数据采集系统的星型网结构及其软件流程。Z igBee协议作为无线电通信技术的一种方式,以其“三低一高”的特点,越来越受到通信行业的推崇,有着非常广阔的市场前景。
The principle, frame structure, features and applicable fields of ZigBee protocol are expounded. The composition, structure and control method of CC2420 are described and the operational principle and control mode of SPI communication module of single chip computer MC68HCg08w32 are discussed. The star network structure of data acquisition system and its software flowchart are designed. As one of the wireless communication technologies, ZigBee protocol has been highly praised in communication industry, with the feature of three-low and onehigh. It will have a broad prospect.
