摘要
设计合理的网络节点是无限传感器网络的核心问题。根据无线传感器网络的工作原理和节点体系结构,设计了以32位ARM7处理器LPC2103为核心,结合2.4GHz无线收发器CC2420、存储器AT45DB041以及外围数字温度传感器构建的无线传感器节点。并给出了节点软件部分的设计流程。
How to design a rational network node is the key problem of WSN. Based on analysis of architecture and working principle of WSN,a node design which adopts 32bits LPC2103 as the MCU, with RF chip CC2420, memorizer AT45DB401 and digital temperature sensor as peripheral equipments is introduced. The system＇s structure, hardware circuits and software flow chart are given too.
