摘要
介绍了基于ARM微控制器的移动传感节点的设计方案,给出了以LPC2214为核心的硬件设计的原理框图。详细阐述了红外传感器电路、射频通讯电路、电机驱动电路及外围接口电路的设计和数据传输流程。该传感器节点具有配置简单、扩展方便、可靠性高的特点。测试结果显示,该移动节点运行稳定,适合应用于无线传感器网络中的数据传输。
A design scheme of a mobile node based on ARM micro-processor is introduced in this paper, The principle graphic of hardware based on LPC2214 is presented. The infrared-sensor circuits,the radio communication circuit,the motor drive circuit and the peripheral interface are expatiated in detail,the data transference flow chat is also described. The node is simple in configure,convenient to extend and outstandingly reliable. The experimental resuits show that the node worked steadily and was appropriate to be applied in the wireless sensor networks.
