【摘要】 随着通信技术的不断发展,短距离无线通信技术已成为无线通信技术新的研究热点。基于IEEE802.15.4标准的ZigBee协议是一种近距离、低复杂度、低成本、微功耗、数据传输速率适中、自组织双向无线通信技术。ZigBee技术已广泛用于工业控制、家庭网络和自动化、楼宇自动化、消费电子、无线传感器网络等多个领域,其有望成为今后无线通信的主流技术之一。本文以ZigBee协议为主要研究对象,主要研究内容及创新点包括以下方面:1、从楼宇/家庭自动化标准切入,以802.11系列标准和BACnet、ZigBee、DLNA、IGRS等协议标准为研究对象,探讨标准制定中出现的两种新动向:在原有标准的基础上,引入新的科研成果,制定派生的技术标准,即构成一个系列标准;采用已得到广泛应用和认同的协议作为底层协议,针对某一领域的特定需求制定相关的上层协议,两者融合制定该领域的新技术标准。2、以Freescale公司第一代ZigBee开发平台MC9S08GT60单片机和MC13192射频芯片为基础,借鉴信息编码技术,提出海明距离为1的水表绝对编码方案,开发了一种基于ZigBee的单环编码直读式无线远传水表,并详细介绍了系统的硬件构成、电子发讯装置的构成及工作原理、低功耗无线远传模块的工作原理以及无线远处水表的软件实现。3、以Freescale公司第二代ZigBee开发平台MC13213芯片为基础,提出了小区业主自有泊车位智能无线管理系统,详细介绍了小区业主自有泊车位智能无线管理系统的组成和软、硬件设计,并验证了此方案的可行性和有效性。4、对Zigaee网络及其路由进行预研:详细论述了新的ZigBee网络建立流程和新设备加入ZigBee网络流程;对zigBee网络路由的基本算法、路由方式、路由发现过程、路由成本算法进行了研究;以S-MAC协议为基础,构建六节点星型网络,并进行了路由仿真。更多还原

【Abstract】 Short-haul wireless communication technology is a new research direction in wireless communication field at present. ZigBee protocol based on IEEE 802.15.4 standard is a short-haul, low complexity, very low-cost, very low power consumption, low data transmission speed, two-way wireless communication standard. ZigBee has been widely used in fields of industrial control, home network and automation, building automation, consumption electron, WSN etc. ZigBee will become one of main technologies in wireless communication field.The dissertation focuses on the research of ZigBee. The main achievements and contents include the follows.1. Based on the analysis of 802.11 series standard and BACnet, ZigBee, DLNA, IGRS protocols in the field of building/home automation, the paper summarizes two ways on standard establishment: use the new research achievements to establish a derivative standard base on the primary standard, then form series standards; based on present rock-bottom protocol, and establish relative topper protocol to meet special requirement to form a new standard.2. Based on the 1st platform MC9S08GT60 and MC13192 of Freescale and codeing technology, the paper proposes a new absolute coding solution and creatively provides a single encoding direct reading wireless remote meter. The dissertation introduces the hardware structure, the structure and principle of electronic sender, the principle of low power wireless remote module and the software realization of wireless water meter in detail.3. Based on the 2nd platform MC13213 of Freescale, the paper provides intelligent wireless management system of owner’s private parking space detailedly describes the structure of the system, hardware and software design and then proves the feasibility and validity of the scheme.4. The paper research the ZigBee network layer and routing algorithm primarily including the flow of building a new ZigBee network and the process of how a device joins a ZigBee network; the basic algorithm of ZigBee network routing, routing ways, routing discovery process, routing cost algorithm. At last, based on the S-MAC protocol, the paper constructs a six nodes star network and simulates its routing.更多还原
