基于 eZ430-RF2500 的无线温度传感器的设计 【摘 要】 随着科学技术的飞速发展,人类目前已经置身于信息时代,信息的获取是实 现信息他的前提,获取信息的一种重要工具就是传感器。综合了传感器技术、嵌 入式计算机技术、现代网络及无线通信技术、分布式信号处理技术等的无线传感 器网络是多学科高度交叉的新兴前沿研究热点领域。在作战人员通信、环境 和气象监测、灾害预警、智能家具、辐射监测等众多领域都发挥着重要作用。低 成本、低功耗、应用简单的 IEEE802.15.4 和 ZigBee 协议的诞生为无线传感器 网络提供了互联互通酶规范。 ZigBee 协议是由 IEEE802.15 4 标准的 PHY 和 MAC 层再加上 ZigBee 的网终 层和应用层组成的,由于网络节点具有成本低、体积小、能量和通信能力有限等 特点,所以此种网络的突出特点是两络系统支持低成本、易实现、低功 耗等。本课题综合运用无线传感器网络技术、现场总线技术和以太网技术,用网络 化思想构建了温度传感器系统。 关键词:MSP430F2274 ZIGBEE CC2500 基于 eZ430-RF2500 的无线温度传感器的设计 【Abstract】 With the rapid development of technology ,human has been in informationera. Obtaining information is the precondition of realizing informationization while one of the most important tools which were used toacquire information is the sensors .The wireless sensor network which combinessens or technology ,wireless communication technology, embedded computertechnology, modern network and distributed information disposal technology together is a multi—study , highly crossed new research fields . It plays an important part in campaign people communication,invironmental and weather control,disaster detection,intelligent building , radiation inspection and so on . The IEEE802 . 15 . 4 and ZigBee protocol offer the criterion for wireless sensor netwok. ZigBee protocol is constituted of IEEE802.15.4 PHY and MAC layer.ZigBee network layer and application layer.because the node has some characteristics such as low.cost...
