摘要
无线传感器网络集成了传感、无线通信、嵌入式计算、微机电系统(Micro-Electro-MechanismSystem,简称MEMS)以及微电子(如SOC)等各项技术,在国防军事、环境科学以及智能家居等领域有着广泛的应用,由于其通常运行在人不能或不便接近的环境,能源无法替代,因此,设计合理的网络节点成为无线传感器网络的核心问题。文中提出了以射频芯片CC2420为核心,配合微处理器的ZigBee无线通信节点设计方案,论述了系统的构成和工作原理,对系统硬件电路和软件设计作了说明。
Wireless Sensor Networks is an convergence of sensor technology, wireless communication technology, embedded computing technology, MEMS technology and System On Chip technology.It has a wide range of applications, such as military, environmental science and smart home environment.Because of running at a remote area where people can＇t or can＇t conveniently reach and might being impossible in substitution of power resources ,the wireless sensor network has a key problem on designing a rational network node. The design of ZigBee wireless solution is presented mainly adopting RF chip CC2420 with MCU. The system＇s structure and working principle, and hardware circuits and software are given too.
