【摘要】 ZigBee遵循IEEE802.15.4新型无线通信网络协议。在简单介绍ZigBee技术的基础上,重点论述了基于星型网络结构的ZigBee基本通信单元的软件、硬件设计。ZigBee基本通信单元由FFD模块和若干个RFD模块组成,实现了FFD和RFD之间的一对多和多对一通信,以及RFD之间的一对一通信。若干基本通信单元可进一步组成复杂通信网络。更多还原

【Abstract】 ZigBee abides by the new wireless communication network protocol stack of IEEE 802.15.4. Based on the introduction of ZigBee protocol,the hardware design and software design of ZigBee basic communication unit which were based on star network structure were discussed emphatically. ZigBee basic communication unit was composed by one FFD and many RFDs. It realized one-to-many and many-to-one communication among FFD and RFDs, the one-to-one communication between RFDs. Many basic communication units could further compose the complex communication network.更多还原
