基于ZigBee的无线通信网络节点设计与组网实现

摘要

针对在恶劣环境中ZigBee网络节点繁多、网络复杂和成本高的弊端,提出一种基于超低功耗单片机MSP430和射频芯片CC2430的无线传感器网络节点设计.应用射频前端芯片CC2591提高发射功率和接收灵敏度,从而延长传输距离.测试结果表明,网络节点上增加单片机和射频前端使得网络工作更稳定,并使网络覆盖范围扩大.%In order to overcome the weakness of large ZigBee node, complex network and high cost in the harsh environment, a design of wireless sensor network node based on super low power consumption MCU MSP430 and RF chip CC2430 is proposed, and RF front-end CC2591 is used to improve the transmission power and receive sensitivity , thus extending the transmission distance. The test results show that the stability of the system is improved and network coverage is increased because of the MCU and the RF front-end.
