摘要
ZigBee无线传感器网络应用最为广泛的技术,在设计开发ZigBee协议之前必须要有相应硬件平台的支撑。硬件平台是整个通信网络的基础,主要负责ZigBee协议所规定频率的射频信道的物理发送与接收、数据采集、控制部分的相关物理接口。在深入研究IEEE 802.15.4和ZigBee协议规范的基础上,给出MT-ZigBee硬件平台的整体框架,同时阐述芯片选型、电源电路、MC9S08GB60与MC13192接口电路和MC13192射频模块的详细设计,通过自主研发,设计了ZigBee硬件平台,并对平台各个硬件模块进行了测试。此平台有所简化地实现了物理层、MAC层和网络层协议栈,在硬件设计上为实现低功耗提供了电路基础。
ZigBee technology is the most widely applied technique in wireless sensor network,which needs the corresponding hardware platform to support its protocols before designing,researching and developing.Hardware platform is basis of the whole communication network system and it is mainly responsible for the phyical transmit and receiving of radio-frequency channel,data acquisition and control partial interrelated physical interface.Based on intensive studying the protocol specification of IEEE 802.15.4 and ZigBee,the MT- ZigBee hardware platform holistic framework,the detailed design about how to select the chips＇ unit type,power cireuit,MCgS08GB60,MC13192 interface circuit and MC13192 radio frequency modules are proposed. Through independent research and development, ZigBee hardware platform is designed, and various hardware modules of the platform are tested. This platform has achieved the protocal stack among physical interface layer, MAC layer and network layer,and provided fundamentals of circuit for the low consumed power control in hardware design.
