摘 要 从20世纪90年代开始，无线网络已经开始进入我们的生活，从全球移动通信系统（GSM ）到蓝牙技术（Blue-tooth）,从无线ATM到无线局域网，这些技术实现了通过无线信道来传递信息，使我们摆脱了有线线路的束缚。ZigBee 作为一种短距离、低速率、低功耗的无线网络技术，已经广泛用于智能大楼、智能家居、自动控制、无线传感器网络等领域。本文就 ZigBee 技术用于无线抄表系统进行研究。 根据楼层内 、小区内各单元之间距离短的特点，又考虑到终端耗能问题等因素，本文采用 ZigBee 技术组建小区内无线网络。再将采集的数据通过 GPRS网络或其它远距离无线传输网络传送到供电局管理中心，通过供电局管理中心的软硬件设备对数据进行采集、处理、分析、管理。 本文设计方案由硬件和软件两大部分组成。在硬件部分中，采用 ZigBee无线通信模块CC2430 芯片为核心构建下层无线网络， 把SIM900A 作为上层GPRS网络的核心模块。本文重点分析了网络工作原理并结合硬件电路进一步分析。软件部分根据不同硬件模块进行设计。本文对下层无线网络中的电表数据采集模块、中继路由模块，以及下层网络与上层网络连接的集中管理模块软件进行了设计。 37440

Abstract From the beginning of the 1990s, wireless networks have begun to enter our lives, to Bluetooth (Blue-tooth), from wireless ATM to wireless LAN technology enables these to pass through the channel information from the Global System for Mobile Communications (GSM) so that we get rid of the shackles of cable lines. ZigBee as a short-range, low-speed, low-power wireless network technology, already widely used in intelligent building, smart home, automation, and wireless sensor networks. This paper studies on ZigBee technology for wireless meter reading system. According to internal floor, a short distance between each unit cell characteristics, but also taking into account factors such as the terminal energy problem, we use technology to build a ZigBee wireless network within a cell. The data is then collected and then transmitted through the GPRS network or telephone network to supply bureau management center, complete data collection by Power Supply Bureau Manager PC software, processing, analysis and management. This paper program implemented by hardware and software parts. In the hardware section, using ZigBee wireless communication module CC2430 chip to build the underlying wireless network as the core, the core module upper SIM900A GPRS network. This paper focuses on the networking works in conjunction with the hardware circuit . According to the software part of the design of hardware module, the main meter terminal module software design, software design and repeater modules concentrator module software design.
