【摘要】 本文介绍了当前世界上非常流行的一种低速无线网络——无线传感网,以及一种基于嵌入式系统而设计的无线传感器网络平台。通过对周遭环境数据的探测和信息的感知途经的分析与实践,借鉴了国内外流行的无线传感器网络协议及技术,搭建了无线传感器信息感知与数据汇聚网络平台。并完成了一种基于嵌入式处理器的低功耗无线传感器网络的设计与实现。本文首先介绍了国内外无线传感器网络的研究现状、无线传感器网络的主要研究内容及关键技术。通过介绍无线传感器网络相关的组网技术,传感器技术,嵌入式系统等关键技术,分析了实现无线传感器网络的技术途径。通过上述的结果比较,结合无线传感器网络的特点,介绍了一种无线传感器网络系统平台的实现方法,并分析了低功耗技术对无线传感器网络的重要性,从而提出了一种基于89S52嵌入式处理器的超低功耗无线传感器网络的设计与实现。基于IEEE 802.15.4协议,对媒体接入技术(MAC层技术)进行了分析,并结合实际的硬件资源,自行设计了一套无线传感器网络系统软件。ARM微处理器具有体积小,低功耗,低成本和高性能等特点,广泛应用于工业控制,无线通讯,网络应用,消费类电子,以及成像和安全产品等领域。本文介绍了基于RISC的ARM微处理器S3C44B0X,设计的无线传感器网络网关的设计与实现。最后对此系统进行了分析和总结,介绍了ARM嵌入式处理器结合嵌入式linux嵌入式系统介绍了码分时分多址接入的分布式拓扑结构条件下的另一种接入方案,并对后续工作作了分析。更多还原

【Abstract】 This thesis introduced in the current world the extremely popular low speed wireless sensor network., as well as one kind of wireless sensor network platform based on embedded system. Through invesgating the environment data to the survey and the information sensation way analysis and practicing, has profited from the domestic and foreign popular wireless sensors network agreement and the technology, has built the wireless sensor information sensation and the data gathering network platform.And completed one kind to embedded processor based on MSP430 the low power wireless sensor network design and the realization.This thesis first introduced the domestic and foreign wirelesssensors network research present situation, the wireless sensor network main research content and the essential technology, accumulate based on protection environment consideration our country carries out the wireless sensor network research and the necessity. Through the introduction of wireless sensor network related network technology, the sensor technology, inserts the type system and so on the essential technology, has analyzed the realization wireless sensor network feasibility. Then through above result comparison and the wireless sensor network characteristic, introduced one kind of wireless sensor network.The microprocessor is small, low power, low cost and high performance, widely applies to the industry control, wireless communication, network application,expense class electron, as well as domain and so on imagery andsecurity product. This thesis introduced based on AT89S52 microprocessor, the design wireless sensor network gatewaydesign and the sensor nodes.Finally the system has carried on the analysis and the summary regarding this, introduced powerpc embedded processor and embedded linux to transplant the embedded system. And introduced another plan based on the time sharing multiple address turned on under the distributional topology condition and continued work which had to do to make the analysis.更多还原
